MOBILE UNIT FOR EXTRACTION FROM BOTTOM OF RESERVOIR AND DEHYDRATION OF SAPROPEL Russian patent published in 2024 - IPC E21C50/00 C02F11/13 F26B3/06 E02F3/88 

FIELD: displacement of soil.

SUBSTANCE: invention relates to hydromechanized treatment of water bodies from silt deposits, as well as to extraction of sapropel of natural moisture using air-cushion vehicles of high cross-country capacity. Mobile unit for extraction from the bottom of a water reservoir and for dehydration of sapropel includes a high-flotation vehicle installed on the water surface of the water reservoir. Plant comprises a submersible soil pump, a water separator, a fluidised bed drying unit, a winch with a rope wound on its drum for lifting and lowering the soil pump to the bottom of the reservoir, a loading tank, flexible hose for supply of compressed air, chute of wet sapropel, air ducts for supply of compressed air to drying unit, pipelines, pulp line, pipe and nozzle with burner. Complex of equipment consisting of a water separator, a drying unit, a loading tank, a winch and a submersible soil pump, is placed on a mobile vehicle with the possibility of switching on this complex of equipment to operation of a compressed air source after the process of movement of the vehicle on the water surface of the reservoir is switched off. Air ducts from the compressed air source of the vehicle are supplied to the ground pump and, after heating by the burner, to the drier and the wet sapropel chute equipped with a pipe made of a filtering net for supply of compressed air through its holes.

EFFECT: higher efficiency of extraction and dehydration of sapropel.
