DEVICE FOR TREATMENT OF WATER RESERVOIRS Russian patent published in 2012 - IPC E02F5/28 E02F3/88 

FIELD: construction.

SUBSTANCE: device for cleaning of water reservoirs from bottom deposits includes two tight loading-unloading reservoirs, every of which is equipped with a nozzle for air supply installed in its upper part, a nozzle for suction of bottom deposits installed in its lower part, and a nozzle for displacement of a hydraulic mixture into a common lifting pipeline installed in the bottom part of the reservoir. The device is equipped with a soil intake assembly of a bucket type, which is common for both reservoirs and where suction nozzles are connected for bottom deposits from both reservoirs, and an additional nozzle of air supply is installed. At the same time nozzles of air supply installed in each reservoir have a branch for air supply to a near-bottom part of the tight reservoir.

EFFECT: increased efficiency of suction process as the suction organ is submerged into dense grain bottom deposits, provision of even soil intake process.
