Homemade flamethrower for melting snow. Experience in operating snow melting plants. Technological process of snow recycling

IN winter period Any owner of a summer house or private house is faced with the need to clear snow from the yard, paths, driveway to the house, as well as the roof. Using special equipment, which many companies produce, this can be done easier and faster. But there is another option: a DIY snowblower. Anyone who is familiar with the operating principle of snow blowers and has certain technical skills can assemble the device themselves.

Snow plows are designed for mechanical removal snow cover in the required area. Their functions include collecting snow mass and throwing it back to the collection point. The engine that powers the car can be electric or gasoline. And the snow removal equipment itself is divided into (with tracked or wheel drive), manually controlled, single-stage and two-stage.

For self-assembly garden equipment you can use a chainsaw engine, an electric motor or, as well as various improvised materials that everyone probably has on the farm. Before you make a snow blower with your own hands, you should familiarize yourself with the types of such equipment and choose an acceptable option for yourself.

Electric snow blowers can clear small areas near the house, for example, a porch or narrow paths. Such a unit is not suitable for clearing large areas of snow cover. In addition, its operation is not effective if there is ice or significant snowdrifts. On the other hand, such equipment is quite compact, easy to operate and convenient to store.

Gasoline-powered self-propelled snowblowers do an excellent job of removing large amounts of snow from large areas. Moving independently, these vehicles have excellent maneuverability and a long ejection range. The technology has enough big sizes, however, during operation there is absolutely no need for the use of physical effort.

Before making a manual snow blower with your own hands, you need to keep in mind that non-self-propelled models designed for cleaning small areas of freshly fallen snow up to 25-30 cm thick. They are mainly used for daily cleaning sidewalks, garden paths and flat roofs. Such devices are quite maneuverable, however, when removing a dense layer, it will be difficult to control the equipment, since you will have to push not only the device, but also the thickness of the snow in front of it.

Helpful advice! When assembling a non-self-propelled snow blower for your home with your own hands, you should use the lightest possible parts, since the equipment will work due to human efforts.

How to make a snow blower with your own hands

Making a homemade snow blower for your home with your own hands is an excellent opportunity not to spend money on purchasing expensive models from leading manufacturers and at the same time avoid labor-intensive clearing of snow from an area with a shovel. In addition, technology self-made will be a source of pride for any owner country house or dachas.

Assemble homemade snow blower It will not be difficult if you have an idea of the operating principle of such equipment and its structure. For clearing snow from paths and yard surfaces own home It will be enough to assemble a screw or rotary model. These are simple machines and anyone can make them. Manufacturing of combined homemade snow blower It’s a little more difficult to do it yourself, but you can do it if you want.

Before you make a snowblower with your own hands, you need to decide on the type of engine. When equipping equipment with an internal combustion engine, you should take into account that it will be a fairly powerful unit that can function on any surface of your site. However, the components and fuel for it are quite expensive. In addition, the disadvantages include the complex technical content of such equipment.

As for a do-it-yourself snowblower with an electric motor, in this case you can use any motor from relatively powerful electrical equipment. A motor from a trimmer or electric saw will do. The advantages of such technology include the availability of electricity, and the disadvantages are the short range of action. To cover the entire area, you will need an extension cord or street wiring with several outlets.

Helpful advice! When assembling an electric snow blower with your own hands, you should take into account that the electric motor requires good waterproofing, because he is afraid of moisture.

You can find it online a large number of videos of homemade snow blowers, viewing of which will help you visually familiarize yourself with the manufacturing technology of various types of snow blowers.

Making a DIY snow blower from a chainsaw

The main advantages of a homemade chainsaw snow blower are:

low cost of components (in addition, you can purchase a used chainsaw at a low price);
high performance of the unit;
the ability to manufacture basic components from available materials.

The disadvantage is that it is impossible to provide the device with self-propelled movement.

When making your own snow blower from a chainsaw as driving force use its motor. To adapt the engine from such equipment to a snow blower, it is necessary to disconnect it from the frame and slightly modernize it. The power of the motor will affect the main indicators of the snow blower: quality of clearing, ejection range and other parameters.

In addition to the engine, the design of the snow blower includes:

auger body (bucket) - you can make it from roofing sheet metal;
auger shaft - a pipe with a diameter of 20 mm (¾ inch) is suitable;
screw surface of the auger - made of sheet iron, some use a conveyor belt;

side parts - for their manufacture use 10 mm plywood or sheet steel;
supporting structure (frame) - it is welded from a profile pipe (angle 50 x 50 mm);
handle - made of pipe with a diameter of 15 mm (½ inch);
shovel for feeding snow into the outlet chute - metal plate 120 x 270 mm.

In your work, you can use the drawings of a snow blower made from a chainsaw with your own hands, posted by users on the Internet.

Forming an auger for a snow blower with your own hands: video of step-by-step production

The main working element of a snow blower is the auger. It consists of cutting rings-blades attached to the drive shaft. A pipe about 80 cm long is used as a shaft. In the center of the pipe you need to cut through hole, into which a shovel will subsequently be inserted to supply snow. When the shaft (pipe) rotates, the blade will throw away the snow.

Before you make an auger for a snow blower with your own hands, you need to develop a diagram or use ready-made drawings according to which the rings will be cut. The auger blades are made of sheet steel. To do this, 4 disks are cut out of metal, cut and pulled out in the shape of a coil. After this, the finished parts of the spiral are welded to the pipe: equally on each side.

Next, having determined the center of the shaft, two blades are welded parallel to each other, which will throw out snow. Metal spacers are welded along the edges of the pipe to fix the screw structure. The spiral blades are attached to the spacers on one side and to the central blades on the other.

Helpful advice! When making an auger for a snowblower from a chainsaw with your own hands, it is very important that the turns of the metal spiral are located at the same distance from the center and towards it. Otherwise, the equipment will vibrate strongly.

When manufacturing the auger body, its length is left equal to the length of the shaft, taking into account the segment for the drive. Trunnions are welded to the edges of the shaft, with the help of which it is mounted on bearings. They are used in a closed design to avoid the ingress of snow and water. You can get a visual idea of how to make an auger by watching a video of a homemade snow blower: in this case, assembling a snow blower with your own hands will be much easier.

DIY snowplow assembly using a chainsaw

The manufacture of the auger body begins with the sidewalls. To do this, two circles are cut out of metal, the diameter of which exceeds the diameter of the screw assembly by 6-7 cm. A sheet of metal of the appropriate size bent into a semicircle is welded to the sidewalls. In the center of the side parts there are holes into which the screw mechanism is inserted. The bearings are welded to the sidewalls with outside. In the section of the pipe under the drive, a driven sprocket is fixed by welding (a sprocket, for example, from a motorcycle will do).

Next, proceed to the installation of snow removal. It can be made from a pipe with a diameter of 100 mm and a length of about 1 m. In order to install the pipe, a hole of the appropriate diameter is made in the auger body. It should be on back wall housings. The snow thrower pipe is inserted into this hole, secured with bolts, and a box is installed on top.

The frame for a snow blower is made by welding into a frame profile pipes. Planks for mounting the engine are attached to the transverse corners of the frame. It should be noted that power point must move freely along the frame and be able to be locked in the desired position. A handle with a homemade engine throttle control attached to it is welded to the frame. snow removal equipment.

Homemade with a longitudinal engine

Depending on the type of terrain, the snow blower frame is equipped with wheels or skids. For flat areas you can use wheels, for bumpy and uneven surface- runners. The base for the runners is made of bars, to which plastic linings are attached for good gliding.

Do-it-yourself snow blower: advantages of an electric model

Electric snow blowers have some advantages over models equipped with internal combustion engines. These include:

relatively quiet operation;
due to the absence of filters, fuel, and spark plugs in the engine, such units are easy to maintain and maintain;
no need to refuel;
light weight of the equipment;
do not emit smoke during operation;
low costs and excellent efficiency.

However, electric snow blowers also have disadvantages, including:

low engine power (up to 2 kW);
constant monitoring of the condition of the electrical cable for damage;
small radius of action (as far as the carrying length allows);
the need to apply effort to move the device.

Helpful advice! Before making a snow blower with an electric motor, select wires whose insulation will withstand the load and will not crack when exposed to frost.

Assembling an electric snow blower with your own hands

The technology for making electric snow removal equipment with your own hands is in many ways similar to the device gasoline models, however, the driving force of such equipment is an electric motor. It could be simplest engine from a power saw, grinder or other power tool. When assembling it yourself, use the drawings of an electric snow blower as a guide. Videos on the topic will help you avoid mistakes during installation.

The designs of the auger assembly and housing can be assembled, as in the example of a snow blower based on a chainsaw. All that remains is to connect the electric motor. It can be done different methods: via gearbox or belt drive. In the first option, the axis of rotation of the motor is located perpendicular to the pipe (shaft). The auger rotates thanks to a gearbox that connects the shaft and the axis of the electric motor.

The second option assumes that the axis of the engine and the auger shaft are placed parallel and connected by a belt. This scheme allows you to quickly remove and mount the electric motor by adjusting the tension of the belt drive. For work, you can use ready-made drawings that can be adjusted to your dimensions.

When starting self-assembly, you should follow some recommendations:

To avoid engine failure as a result of stones and other objects getting into the auger, it is necessary to use safety bushings and bolts. Thanks to this, if the load is exceeded, the bolts will fail, and the engine will not jam;
the width of the auger body is selected taking into account the size of the surface requiring cleaning;
When installing a single-stage snow blower, the outlet chute should be located on the top and side of the body, which will allow the thrown snow to travel a shorter distance.

DIY snow blower layout from a trimmer

Not all models of electric scythes are suitable for assembling a homemade snow blower from a trimmer. If the trimmer has a curved rod with rotation transmitted by a steel cable, then such a tool is low-power and is not suitable for making a snow blower. One of the requirements is that the trimmer has a straight rod and transmits rotation from the motor to the reel through a gearbox and a rigid shaft. Such devices are more powerful and can be used for snow blowers.

Before you make your own snowblower from a trimmer, you need to check that you have everything the necessary tool. You will need welding machine, grinder, drill. The sequence of work is as follows:

the body can be made from small metal barrel, which must be cut approximately 15 cm from the bottom. A hole is made in the center of the bottom of the barrel into which the protruding element of the gearbox will be placed. Holes are drilled along the edges - at a distance coinciding with the fastenings of the shield on the gearbox itself;
a hole is made on the side of the barrel square shape 10 x 10 cm in size for throwing away the snow mass;

the third part of the open body must be covered with a sheet of tin so that the hole for the snow to come out is strictly in the center;
To make a rotor you will need four blades. It is necessary to cut four rectangular plates measuring 25 x 10 cm from sheet metal. These blanks must be cut so that the shape of the blade is obtained. After this, they are welded to the trimmer disc;
a snow drain can be made from the remaining parts from a metal barrel. To do this, a rectangular strip of 15 x 30 cm is cut out. This blank must be bent and side parts 10 cm high must be welded to it. Thanks to them, the snow will be directed in a certain direction when thrown;
making a spatula. It is made from sheet metal 30 x 40 cm. The edges of the plate are folded so that the sides are about 2 cm high;
the snow drain is welded to the body in the place where the ejection hole is located. The blade is fixed from below. The gearbox is secured with bolts. The rotor is installed like a trimmer blade.

A video of a snow blower made from a trimmer with your own hands will help you get acquainted with the assembly process in more detail.

DIY rotary snow blower

The main components of a homemade do-it-yourself rotary snow blower are:

internal combustion engine equipped with a muffler;
fuel tank;
throttle control cable.

To manufacture all elements of the snow blower, you will need to have lathe. It is used to adjust all the parts of the mechanism to the right size. If such equipment is not available, the manufacture of a rotor can be ordered in a workshop according to the sketches you have.

Activities for constructing a rotary snow blower can be divided into several stages:

assembly of the screw mechanism;
rotor manufacturing;
housing installation;
frame device.

Having made each unit separately, they are assembled into one structure. To ensure that the snow blower has a presentable appearance, it is painted after assembly.

Manufacturing of components for a rotary snow blower

The manufacturing technology of the auger mechanism is similar to the design of an auger for a snow blower made from a chainsaw. A dense (10 mm thick) conveyor belt can be used as screw blades. The dimensions of the screw assembly must correspond to the dimensions in the drawings.

The rotor is made of sheet metal 2.5-3 mm thick. Using a compass, you need to draw a circle of the required diameter on a sheet of paper and cut it out with a grinder. To make the blades, a blank part from an electric motor is taken as a basis. Blades are formed from sheet metal. They are welded at equidistant distances from each other to a steel disk connected to the hub. The number of blades must be at least four.

The frame for the snow blower is assembled by welding sections of metal corner into the frame according to the existing diagram. All components of the frame are attached using bolted connections.

Helpful advice! Rotary snow blowers should use more powerful bearings that can withstand the beating of the rotor mechanism.

When all the components of the snow blower are ready, they begin to assemble them into a single unit. On rotary mechanism install the auger shaft. Then this entire mechanism is fixed to the frame using bolts and a pressure ring. The rotor is attached to the frame using a special bracket. A plastic pipe with a diameter of 100 mm is used as a snow thrower for a homemade rotary snow blower.

Advantages of combined models of snow blowers

Compared to auger units, combined snow removal machines are more efficient in operation, since the load is distributed between both the auger and the rotor. They have sufficient power and can cope with clearing an area of impressive volumes of snow. Among the advantages of homemade rotary snow blowers are:

excellent maneuverability and high performance of equipment;
depending on the engine used, the snow throw range can reach 12 m;
the ability to adjust the width of the snow cover;
The light weight of the machine (up to 20 kg) allows you to cope with cleaning adjoining plot(including women);

the ability to repair a snow blower yourself;
low cost of materials for the manufacture of all components of the unit.

Making your own rotary snow blower is quite a complex and painstaking task. If you are poorly versed in technology, do not have certain skills, or do not have the necessary tools, then buy factory model While finances do not allow, you can make your own snow shovel.

Making a snow blower with your own hands: videos about self-assembly

For many it may seem self-assembly Snow plows are a very challenging task. Justifying the saying “it’s better to see once than to hear a hundred times,” many craftsmen post thematic videos on the Internet. The videos contain the main points of assembling homemade snow blowers, as well as information about the components used to construct them.

On the Internet you can find a huge number of video instructions, which present various options homemade snow removal equipment: based on a chainsaw engine, as well as an electric motor. The stories describe the method of manufacturing a screw mechanism and provide possible materials for their manufacture.

On the Internet you can find many ready-made drawings and assembly diagrams for snow blowers of various models. You can use them to make your own model, and all dimensions in the drawings can be adjusted to apply to an individual snow blower.

Getting acquainted with the video materials will give useful information about how to properly prepare for work and set up a snow blower. The DIY snow blower repair video contains visual information about common faults and breakdowns, how to fix them, as well as the correct Maintenance devices.

Having studied in detail the proposed drawings, diagrams, step by step instructions and video materials, everyone can try their hand at making a homemade snow blower. After all, in everyone’s garage or workshop there is old lawn mower, chainsaw or other tool that is suitable for adapting it to a snowblower. And for those who doubt their capabilities, it is better to purchase a factory model.

On roofs with sufficient load-bearing capacity, all standard snow melters can be used. network water and power supply.

And were developed especially for roofs with limited load-bearing capacity. Their difference from each other is in the heat source. In other areas, roofing snow melters can also be used, but it should be taken into account that due to small sizes water circuits, they are sensitive to the presence of debris in the snow mass.

OSA-7.01

OSA-7.01 snow melting plants operate on network water. If it is possible to connect to heat on the roof, a snow melter using water from the heating network is the most optimal choice. It is advisable to use an intermediate circuit with antifreeze between the IHP and the unit.


Rice. 4. Scheme of operation of OSA-6.10

Features of operation

Before starting work, it is necessary to fill the snow melting hopper cold water.

All OCA snow melters are equipped with mechanical filters to prevent floating debris from entering the sewer system. The solid sediment contained in the snow mass is almost completely retained in the snow-melting bunker due to its own constructive solutions our design bureau.

The snow melting bunker is cleaned as solid sediment accumulates. To do this, you need to stop the pumps, turn off the power supply, drain melt water into the sewer. Solid sediment is removed manually.

The frequency of cleaning a roofing snow melter depends on the degree of snow contamination and the compliance of the installation’s performance with the size of the serviced area.

During operation, it is necessary to monitor the condition of the circulation pump filter. The need to clean it can be judged by the decrease in pressure in the irrigation circuit - the water jets become weak. To clean the pump filter, you need to stop it, turn off the power supply, remove the pump from the water, and remove accumulated deposits.

Pumps must be maintained in accordance with their operating instructions - check the oil level in a timely manner and, if necessary, top up.

These are simple and reliable domestic snow melters for progressive companies, which can significantly reduce the cost of cleaning areas in winter using Newest technologies melting snow instead of its outdated and expensive removal.

The lineup

The lineup snow melting plants OSA covers the widest range possible options: by design – transportable, mobile, roofing, stationary; by heat sources - from network water, from steam, from hot water boilers at any type of fuel, from electric heating elements. Snow melting performance is limited only by the imagination of customers. The loading method, autonomy, and degree of automation can be anything. It is possible to equip the units with a compact complex for purifying melt water from mechanical impurities and petroleum products. We can integrate a snow melting plant into the existing facilities of our partners. We can make any non-serial unit that the customer needs.

On network water

Liquid fuel

OSA liquid fuel snow melting machines are used where it is not possible to connect to the heating system of buildings or where mobile snow melting plants are required.

As a rule, diesel fuel is used in such snow melting machines, but it is possible to use waste motor oil, fuel oil, heating oil.

The design options for snow melting machines running on liquid fuel can be very different:

on the frame - installed in in the right place, moving requires a truck of sufficient carrying capacity and a truck crane (if the vehicle is not equipped with an appropriate hydraulic manipulator);
on a transport trolley - for moving around a closed area (installations with a capacity of up to 60 m3/hour); such units are transported around the city in the same way as installations on a frame;
on a low-bed trailer - for moving on public roads (installations with a capacity of over 80 m3/hour);
on a KAMAZ chassis - for prompt arrival on site and immediate start-up.

All mobile snow-melting installations can be equipped with autonomous diesel generators (mandatory on KAMAZ). We recommend installing SDMO generators, but the customer's wishes are primary.

Operating principle of liquid fuel units:

snow melting machines of this type use heat obtained during the operation of liquid fuel burners installed on special hot water boilers;
the entire system is placed in a snow-melting bunker and immersed in melt water;
heat from hot gases produced by fuel combustion, is transferred to melt water through the walls of the combustion device and fire-tube heat exchangers combined with the furnace through the gas path;
heated melt water from the snow-melting hopper is supplied by a circulation pump through special channels to the melting zone, where it transfers its heat to the snow mass;
To intensify the melting process, hydraulic mixing of melt water and snow mass is provided;

Gas fueled

OSA snow melting plants at gas fuel are used where it is possible to connect to the gas main.

Melting snow with snow melting plants running on gas fuel is the most economical.

Appearance and the principle of operation of gas snow melters is similar to liquid fuel ones. They differ only in the burners.

For roofs

OSA snow-melting installations for roofs can operate on electricity and hot water from the building’s heating system (network water).

With sufficient bearing capacity Not only special roofing snow melters can be used on the roof, but also conventional snow melting installations.

Operating principle of OSA electric snow melting plants:

electric heating elements heat the non-freezing liquid in a special container of the roofing snow melter;
circulation pump supplies heated non-freezing liquid to the heat exchanger;
through metal constructions heat exchanger transfers heat from the non-freezing liquid to melt water;
melt water is taken from the snow-melting hopper by a circulation pump and is supplied through special channels to the melting zone, where it transfers its heat to the snow mass;
the non-freezing liquid, which has partially given off heat, is returned through the return pipeline for heating;
Excess melt water formed when snow melts is drained by gravity into the sewer system through overflow edges.

Stationary snow melting stations - turnkey - from 25 million rubles.

Stationary snow melting stations OSA can operate on any type of fuel, on hot water from the building heating system (network water), on return water CHP, on sewage, on technical water enterprises.

Stationary snow melting points are usually built according to individual projects. They are buried reinforced concrete structures with snow-melting and sand-catching chambers, built-in technological equipment.

When designing stationary snow melting plants, it is necessary to take into account the possibility of discharging melt water to treatment facilities.

Features of operation

To connect the gas main, a permit for the use of a snow-melting installation using gas fuel is required!

Design, laying of gas mains, connection to them gas burners authorized organizations are involved!

The uninterrupted operation of liquid fuel snow melting machines largely depends on the quality of the fuel used.

At stationary snow-melting stations, in order to avoid accidents, when the sliding covers are open, you should not approach the edge of the snow-melting chamber.

Before starting work, it is necessary to fill the snow melting hopper with cold water. In OSA snow-melting machines operating on liquid and gas fuel, a “dry” start is provided, however, to speed up the process, it is recommended to fill the snow-melting hopper with cold water to the minimum level before starting work.

All OSA snow-melting installations are equipped with mechanical filters to prevent floating debris from entering the sewer system. The solid sediment contained in the snow mass is almost completely retained in the snow-melting bunker thanks to KBEM Metallist-OSA’s own design solutions.

The snow melting bunker is cleaned as solid sediment accumulates. To do this, you need to stop the pumps, turn off the power supply, and drain the melt water into the sewer. Removal of solid sediment is carried out manually (at stationary snow-melting stations - with the help of special equipment).

The frequency of cleaning snow-melting installations depends on the degree of snow contamination and the compliance of the installation’s productivity with the size of the serviced area. Stationary snow melting points are cleaned no more than once a year - during the off-season.

During operation, it is necessary to monitor the condition of the circulation pump filters. The need to clean it can be judged by the decrease in pressure in the irrigation circuit - the water jets become weak. To clean the pump filter, you need to stop it, turn off the power supply, remove the pump from the water, and remove accumulated deposits. To remove heavy pumps, OSA snow melting installations are equipped with winches.

Pumps must be maintained in accordance with their operating instructions - check the oil level in a timely manner and, if necessary, top up.

Important!

The customer, on his own, prepares a flat area for placing the snow melting plant, taking into account its dimensions, and supplies the communications necessary for its operation to the connection point of the snow melting machine: pressure and return hot water pipelines from the heating system, pressure pipeline (or flexible hose) cold water With shut-off valves, drain pipeline for melt water, power cable with grounding.

The customer provides the hot water parameters specified in the installation passport; With other hot water parameters, the performance of snow melting plants for melting snow may differ from the declared one.

Advantages of OSA snow melting plants

automatically supported optimal temperature in a snow melting chamber;
intensive two-level heat and mass exchange between the coolant and the snow mass is ensured;
the snow-melting zone is maximally freed from any structures that impair, firstly, heat and mass transfer, and, secondly, the possibility of cleaning the snow-melting zone from accumulated debris;
the snow melting system does not change its performance within sufficiently large limits when any possible debris gets into it;
accumulation of debris in the snow melting system does not lead to its breakdown;
the required reliability of OSA snow-melting installations is ensured by deep redundancy of the main mechanisms and systems, as well as the ability to control them manually;
our installations are several times cheaper than imported ones;
the cost of repair and maintenance of OSA snow melters is an order of magnitude lower than foreign ones;
our snow melters are simpler and more reliable, they do not require maintenance special training personnel;
they are not afraid of domestic snow;
in case of automation failures, they can work in manual mode until the fault is eliminated;
any components are always at hand.

Not only mayors have to think about what to do with mountains of snow.

Owners face a similar problem dacha and owners private houses.

It happens that there is simply nowhere to throw the snow away from the entrance, and the accumulated snowdrift needs to be disposed of somehow.

Exit The current situation could become a mini snow-melting installation.

There are different models on sale, but they all have high cost. To process snow near your home or cottage, it is often easier to make a compact and inexpensive snow melting machine with your own hands.

Factory models have the following advantages:

reliability;
ability to recycle large volumes of snow;
the ability to select the unit required power;
high Efficiency;
large selection of systems used different types of fuel;
work in automatic and manual control mode;
affordable price domestic snow-melting installations (if compared with foreign systems);
availability of a system garbage collection;
availability of special filters(makes it possible to pour water obtained by melting snow into the sewer);
repair and warranty service installations by the manufacturing company.

Disadvantages of factory models:

for a private person price apparatus heavy;
for loading snow into a snow melting device it is necessary special equipment;
required for installation to work staff;
when using stationary systems you need communications.

It’s easier for a private person to do small do-it-yourself snow melting plant for your home. This approach has several advantages:

You can create an installation from scrap materials;
will be required small financial investments;
don't have to take it permission for operation;
such a device - ideal option for a summer house and a private house when you need to melt down A little snow.

But there is homemade snow melters and flaws:

average level of efficiency;
it is impossible to process a large volume of snow;
processing speed is lower than factory systems;
If installed incorrectly or on an uneven surface, the system may be damaged. unsafe.

Preliminary calculations of volume and power

Before you start making a snow melting machine for a private home, you need to calculate volume, and also determine the required power.

First you need to understand how big territory It is planned to clear the snow. Then you need to find out the average thickness snow cover in the region, this number should be divided by 24 hours. This way you can determine the required performance installations.

For example, plot area 5 acres(500 m²), average snowfall – 5 cm(0.05 m).

Then required system performance = (500 x 0.05)/24 = 1.04 m³/h.

If there is space on the site to temporarily store snow, this value can be divided by 2. That is. it is enough to make a car that would 1 hour melted 0.5 cubic meters snow.

And one more very important point in the calculations. As a rule, on the site itself there is somewhere to throw away the snow, the most problem areas:

entry group,
area in front of the garage,
porch.

Paths and blind areas are usually small in width and do not have time to accumulate large snowdrifts throughout the winter.

Therefore, in the case where the snow on the site can mostly melt on its own, you can consider only the most complex places.

You should not greatly underestimate the power of the snow melter, because then the device will have low performance.

As energy source can be used different types fuel. It is very good if a private house has its own gas boiler room. In this case, melting 1 cubic meter of snow will be leaving 0.02 Gcal/h. In this case, it is important to provide for draining the coolant from the pipes supplying heat from the boiler room after using the installation.

Good, but Expensive option - use a separate one for the snow melter gas boiler with outline filled antifreeze. In this case, you can fill the coolant once and not drain it again.

Snow melters can also work on diesel fuel. On 1 m³ snow will cost about 3 liters of winter diesel fuel. But this option is considered not the most successful for a homemade snow melter.

On 1 cubic meter will leave 25 kW/h. There will be a snow melter low-productivity, because in private homes it is usually not possible to connect to a power of about 100 kW/h.

Types and options

There are several ways to do it yourself make a snow melter. The following are possible options:

With connection to heating point building. Ice and snow are placed in a melting hopper with water heated to 30ºC. Mass goes down to the bottom, happens mixing. The water level rises, draining through the drainage hole. At the outlet, the water has a temperature of about +10ºС, i.e. no thermal pollution occurs. Due to the fact that water is removed from the installation, and not a mixture of liquid and ice, melt water can be drained into sewer well . Debris and sand will remain at the bottom.
Electrical installation. It consists of a receiving hopper in which heating elements used to heat the liquid are located. Before starting the installation, it is filled with warm water. Snow begins to melt after being placed in water. The water level rises and it drains through the drainage.

Sheets are suitable for making the structure stainless steel thick 2-3 mm, from them you can make snow storage bin.

When making, consider hopper height so that it is convenient for you to throw snow shovel.

Some craftsmen make a ramp near the installation so that when using a wheelbarrow, they can unload snow from it directly into the bunker, rather than throwing it with a shovel.

At the bottom of the bunker there are heating elements(For electrical installation) or coil for a water circuit with coolant. In this case, the circuit must be closed and transfer heat by contacting the lower layer of water in the bunker. The circuit is connected to a heat source and usually contains a circulation pump. A gravitational circulation option is also possible, but in this case there must be a difference in height.

Heat source May be:

electric heater,
solid or diesel fuel burner,
a conventional wood-burning stove or similar device.

Drawings and diagrams

The easiest way to make a snow-melting installation consists of one section. It is in it that the snow mass will be heated. Owner country house, having decided to make a snow-melting installation, can take the following as a basis: scheme.

Device based on drawings of a snow melting plant "WASP"

System based on a snow melting plant "Gorynych"

Step by step guide

Simple snow melting plant option for private use can be done like this:

Prepare capacity. This can be a barrel with a volume of 100 liters. There is another option for constructing a bunker - it can be made by welding several sheets of stainless steel.
Do it in boot bunker holes for drain pipes. Buy hoses and install them.
If you plan to use water from the heating system of a private home to heat snow, buy pipes. Connect the installation to the system.

Those home owners who wish fast melt the snow, they can make a structure out of barrels 100 l. In its lower part you need to make a hole to drain the melt water, the snow will be heated blowtorches. Instead of a barrel you can use bitumen cooker large volume.

It is important to install the structure on flat ground, taking into account the regulations fire safety. Such an installation must not be left unattended.

Exploitation

When operating snow melting stations, it is important to pay attention to the following issues: ecology.

It is forbidden to reset dirty melt water into bodies of water, you shouldn’t pour it onto the site either. When melting dirty snow, melt water should be discharged to the sewer.

A snow melting machine used in a private home consists of:

containers for melting snow,
heater,
pipes for draining melt water.

Heating of the snow mass can be carried out through work gas-water heat exchanger. Many homeowners choose the option of installing a system with electric heating element. If it is not possible to connect the snow melter to a gas boiler room or electrical networks, you can use diesel generator.

Devices with burners are common; they are required to burn fuel. Combustion products enter the heat exchanger, it is usually installed at the bottom of the bunker. Metal surface heats up the snow is melting. Water gradually accumulates in the container. When she reaches height, on which are located drain pipes, That flows out of installation.

In order for the snow to heat up faster, the bunker is filled 1/3 with warm water. For additional irrigation of the snow mass it is possible to install pump. Hot water, falling on dense snow, breaks it. This increases the contact area between ice and water, promoting acceleration melting process.

In systems that operate from a heating network, the snow mass is heated by hot water supply.

A homemade snow melting installation requires regular service. Need to cleanse hopper and heat exchanger surface from:

mechanical debris;
sand;
scale;
raid.

Conclusion

You can make a snow melter with your own hands fast and inexpensive. The easiest way (but more expensive to use) is to melt snow in containers big size watering it hot water taken from the heating system.

Making snow melters that are cheaper to operate will require:

resources,
time,
knowledge.

But perhaps in your case it will be completely justified.

For enterprises who need to regularly process snow, it is better to give preference powerful factory systems. In the long term, it will be cheaper than using a self-made snow melter.
