Abstract

FIELD: removal of snow. SUBSTANCE: heated bunker 4 enters mud collector 9 and passes through water collector 13 and heat exchanger 18. The latter is connected at its input with feeding tank 15 by water trunk and with pump 20 and shower collector 21 at its output. Shower collector 21 by gas pipeline is at input connected with exhaust branch pipe of engine 23 and with heated cavity of bunker 4 at output. Exhaust gasses, passing through heat exchanger give it part of warm to heat water and passing through bunker are heating it and go out into atmosphere. Heated water is fed in shower collector 21 by pump 20 and is sprayed in bunker on snow, melting it. Water and road mud get into mud collector and water through hole 10 pours into water collector 13, from which it is through mouth 14 step by step removed. Road mud is left in mud collector and is removed through mouth 11, as required. Water from feeding tank 15 is fed into heat exchanger. Feeding tank 15 has inlet pipe 16 and outlet mouth 17. EFFECT: snow melter is used to remove snow from road covers. 2 dwg

Description

 The invention relates to devices for removing snow and ice from road surfaces, and specifically to snow melting machines.

 Known snow melter containing a container for melting snow with a loading hopper and a protective grill. A burner, intensifiers and partitions are mounted in the tank, forming a labyrinth for the direction of water movement.

 A disadvantage of the known device is the presence in it of a special burner device for melting snow and the need for additional fuel consumption for the operation of the burner device.

 A snow melter is also known, containing a self-propelled chassis, a screw feeder, a conveyor, a heat generator.

 A disadvantage of the known device is that the process of melting of fragmented snow occurs in an increasing volume of water due to snow. The water temperature decreases and the water needs to be heated, consuming electricity and additional fuel to ensure the operation of electric intensifiers and a heat generator.

 The aim of the invention is to reduce the energy intensity of the snow melter.

 This goal is achieved through the use of heat from the exhaust gases of the snow melting engine and the elimination of additional heat sources that provide snow melting.

 The snow melter is equipped with a heated hopper that exits into the hopper with a dirt collector, also passing through the water collector, heat exchangers connected via a water line at the inlet to the supply tank, at the outlet with a pump and a shower manifold, through a gas line connected at the inlet to the engine exhaust pipe, at the outlet heated hopper cavity. Water enters the heat exchanger from the supply tank, equipped with an intake pipe and a drain neck. The process of snow melting is carried out in the receiving hopper due to the heated walls of the hopper and the water heated in the heat exchanger, which is sprayed from the shower manifold onto the snow above the grating of the dirt collector, causing it to melt. Preliminary crushing of ice and snow and additional heat sources are not required. An increase in the volume of water in the catchment does not affect the snow melting process.

 Conducted patent studies have shown that the set of distinctive features characterizing this technical solution is unknown, which allows us to conclude that its criterion of "significant differences".

 Figure 1 shows a snow melter, section; figure 2 is the same, a top view.

 The snow melter contains a self-propelled chassis 1, on which a screw feeder 2 and a conveyor 3 are installed. Under the unloading part of the conveyor 3 there is a heated hopper 4, consisting of an inner wall 5 and an outer wall 6, which form a heated cavity 7 that communicates with the outlet pipe 8. Into the hopper 4, the dirt collector 9 exits. There are openings 10 in the side walls of the dirt collector, at the bottom there is a mouth 11 for removing dirt, and in the upper part there is a grill 12. The dirt collector 9 passes through a water collector 13 having a drain neck 14. Inside and a sump 13, there is a supply tank 15 with a suction pipe 16, the end of which is located below the level of the supply tank 15, and a drain neck 17. The supply heat exchanger 18 is connected via a water line at the inlet through the pipe 19 to the supply tank 15, and at the outlet to the pump 20 and shower manifold 21, through the gas line is connected at the inlet through the pipe 22 with the exhaust pipe of the snow melting engine 23, at the output it is connected through the pipe 24 with a heated cavity 7 of the hopper 4.

 Snow melter works as follows.

 The exhaust gases of the running engine 23 through the pipe 22 fall into the heat exchanger 18, in which they give part of the heat to heat the water. After passing the heat exchanger 18 and the pipe 24, the exhaust gases enter the heated cavity 7 of the hopper 4. Passing through the cavity 7, the exhaust gases heat the inner wall 5 of the hopper 4 and through the pipe 8 into the atmosphere. At the same time, the pump 20 pumps water through the heat exchanger 18, where it is heated from the exhaust gases of the snow melting engine, and delivers it to the shower manifold 21. Flowing down the inner wall 5 of the hopper 4, the water enters the dirt collector 9 and enters the water collector 13 through the holes 10 in the side surface 13. , where it accumulates in its lower part at the drain neck 14. Through the intake pipe 16, water is sucked into the supply tank 15 and from it through the pipe 19 enters the heat exchanger 18.

 When the snow melter moves, a mass of snow or ice is fed by the feeder 2 and the conveyor 3 into the hopper 4. Since the wall 5 of the hopper is heated by the exhaust gases of the engine, the snow begins to thaw and slide along the inclined walls 5 of the hopper 4 to the grate 12 under the shower manifold 21, from which to the snow the mass is heated water. Intensive melting of snow mass occurs in water jets.

 Road dirt, passing through the cells of the grill 12, accumulates in the dirt collector 9 and then is removed through the mouth 11. Large fractions of road dirt remain in the hopper 4. Melt water flows into the dirt collector 9 and through holes 10 into the water collector 13. From the water collector 13, water is drained through the golovin 14. When draining the water from the reservoir 13, the water from the supply tank 15 does not drain, because the intake pipe 16 is located above the water level in the tank 15. When the snow melter stops working for a long time, the water from the tank 15 is drained through the neck 17.

 The design of the proposed snow melter in comparison with the design of the prototype is much simpler. The reduction in the number of used mobile mechanisms and service units increases the reliability of its work and reduces operating costs. The absence of a heat generator in the snow melter, which is used in the prototype for heating water, allows you to save fuel to ensure its operation, thereby reducing the cost of removing snow from road surfaces.

 The melting of snow is not in the water reservoir, as in the prototype, but in the bunker under the shower collector allows you to abandon the preliminary crushing of snow by a crusher and the final crushing of snow by intensifiers during an electric pulse discharge, i.e. refuse to use electric energy.
