SU1495409A1 - Arrangement for moistening snow in snow removing machine - Google Patents

Abstract

The invention relates to snow removal machines and the construction of snow-ice roads. The purpose of the invention is to increase efficiency by moistening the entire mass of snow. The snow wetting device in the snowplow contains a blade rotor 1, the body 2 of which communicates with the evaporation chamber 8 and the discharge nozzle 3. When the snow accelerates by the rotor, 1 part of the snow enters chamber 8, where it is melted and mineralized with salt from the bunker 12. Generated steam through a superheater 6 is fed to the nozzle 3 and moistens the snow supplied by the rotor 1. The mineralized water is injected into the nozzle 3 by the nozzle 16. The microwave inductor 17 promotes the heating of the injected water, creating a condition for uniform wetting her mass of snow. 2 Il.

The invention relates to snow removal machines and the construction of snow-ice roads.

The purpose of the invention is to increase efficiency by moistening the entire mass of snow.

Figure 1 shows the device, side view; figure 2 - exhaust pipe, axonometrics.

The snow wetting device in the snowplow consists of a blade rotor 1 located inside the housing 2 that is connected to the discharge port 3. In the discharge pipe 3 a channel 4 for supplying superheated steam is attached, connected by pipe 5 to the steam superheater 6, which is connected by pipe 7 with the evaporation chamber 8, the latter communicates with the housing 2, through the through window 9, in which the damper 10 is installed. In the evaporation chamber 8, a dividing partition 11 is mounted and a hopper 12 is connected to the chamber 8, the mineral is dispensed salts. The evaporation chamber 8 is connected by a pipe 13 to a pump 14, which is connected by a pipe 15 to a nozzle 16 fixed in the discharge port 3.

On the discharge port 3 there is a spiral radiator 17 of electromagnetic microwave oscillations of rectangular cross section, in the walls of which, facing the discharge port 3, slots 18 are made, which coincide in place with gaps (not shown) anapogic in size and shape, filled in two adjacent mutually perpendicular walls of the outlet nozzle 3. At the beginning of the emitter 17 there is a grating 19, on both sides of which the inputs 20 of the microwave power from the generator (not shown) are located in mutually perpendicular directions,

The device works as follows.

As the snow moistening unit moves forward, the blade rotor 1 rotates from the drive shaft (not shown) and the snow enters the inside of the casing 2 in the axial direction, is captured by the blade rotor 1 and accelerates along the shell surface of the casing 2 within the acceleration sector, after which ejected by centrifugal forces through the discharge nozzle 3 onto the roadway. When the flap is open, W is part of the snow,

being driven by a blade rotor 1 hour through the through window 9, it enters the evaporation chamber 8. Due to the heat supplied to the bottom of the evaporation chamber 8, the snow melts. The water formed as a result of snow melting intensively evaporates, and the water level in the evaporation chamber exceeds the gap between the partition wall 11 and the bottom to form a water seal. Due to the obliquely installed control valve 11, most of the steam enters through pipe 7 to the superheater 6, where the additional heat supply provides for an increase in temperature and vapor pressure, and the superheated steam through pipeline 5 then enters channel 4, from where it is fed into the discharge port 3 in the direction of scatter snow lobed rotor -1, providing heating and partial melting of the snow on the mantle surface and adhesion between a snow fragments. A smaller part of low-pressure water vapor flows countercurrent through the through window 9 into the fixed housing 2, providing partial melting of the snow when the blade rotor 1 accelerates and thereby reducing snow adhesion to the surface of the fixed casing 2. From 5 bunker 12 to the evaporation chamber 8 continuously enters the salt component. C. Using pump 14, the saline water from chamber 8 through pipelines 13 and 15 under pressure from pump 14 is supplied to nozzle 16 and sprayed in the cross section of the discharge port 3. The presence of water in the snow dramatically increases the dielectric loss coefficient of the latter. Water mineralization contributes to an additional increase in dielectric loss efficiency.

During the passage of snow particles moistened with mineralized water in an electromagnetic microwave field generated by the radiator 17, the entire mass of snow selected on the snow-ice road under construction is additionally moistened in the exhaust pipe 3.
