MOBILE SNOW MELTING PLANT Russian patent published in 2019 - IPC E01H5/10 

FIELD: machine building.

SUBSTANCE: invention relates to equipment for cleaning streets and roads from snow mass and can be used in municipal engineering, transport and industrial enterprises and other territories. Mobile snow melting plant includes two-stage hydrocyclone-oxidiser 12 with cylinder-conic housing, tangential branch pipe for supply 29 of contaminated liquid, branch pipes for removal of slurry 31, 32 and foam 34, purified water 33, oxidizer supply branch pipe 30 and bubbling device, secondary swirling housing with blade swirlers and filter. Proposed plant comprises snow melting chamber 1 with thermo-panel 2 and thermal insulation layer 3 along outer casing, in lower part of which there are lines without cleaning and with cleaning with fluid discharge valves 6 and 9 connected to drain openings of melting chamber 27 and 28. Pipeline with cleaning comprises hydraulic pump 10 with electric drive 11 for supply of contaminated liquid into two-stage hydrocyclone-oxidiser through tangential branch pipe 29 of liquid supply. Sludge removal pipes 31, 32 and foam 34 of two-stage hydrocyclone oxidizer have outlet to reservoir for collection of contaminant 13, and thermo-panel 2 and electric drive 11 of hydraulic pump 10 are connected to control unit 21 operating on signals from control panel 22.

EFFECT: technical result of disclosed invention consists in improvement of efficiency of cleaning snow mass due to melting and mechanical and chemical cleaning, improving ecology, as well as increasing process efficiency and economy.
