GRAVITY LINE CLEANER Russian patent published in 2015 - IPC B08B9/49 

FIELD: process engineering.

SUBSTANCE: device for cleaning of gravity lines comprises combined spill way at pull cable. Spill way with thin wall is arranged at top section while bottom part of combined spill way is a float-type design to accommodate the reverse slitted spill way while fastening cable is fed in pulsating mode. Note here that precipitate is efficiently displaced at collector bottom by powerful jet developed by reverse slitted spill way at bottom part. Device does not touch the entire surface of said collector since it is fitted in collector with circular clearance of 3-5 mm. Hydraulic jump is created at top part with thin wall at combined spill way tail-water that carries the precipitate at notable distance from combined spill way. Pulsating mode of fastening cable creates the pulsating mode of combined spill way to displace precipitate with stream without whatever extra power outlays.

EFFECT: ruled out extra expenditures, reliable operation of gravity lines.
