WATER TREAMENT DEVICE Russian patent published in 2015 - IPC B04C9/00 B01D36/00 

FIELD: machine building.

SUBSTANCE: water treatment device comprises a hydrocyclone with feeding and drain branch pipes, an input, output and washing pipelines with appropriate branch pipes and gate valves, treatment wastes gathering tank with quick-detachable lid and pipeline valve, pipes filter installed in the inner part of the hydrocyclone, its lower end is dead and a corrosion-resistant flanged drain branch pipe is threaded to the upper end, and is flange-mounted to the outlet branch pipe of the hydrocyclone. The device is additionally equipped with tank connecting the output and washing pipelines. The washing pipeline is equipped with washing pump, thus permitting periodic change of the operation mode. The outlet hole of the feeding branch pipe in the hydrocyclone is made as a segment with the arc length l ≈ 1.55d, where d is diameter of the inlet hole of the feeding branch pipe in the hydrocyclone and is set at the angle of φ = arctg0.32(0.12÷0.4) to the perpendicular of the hycrocyclone axis. Flooding of the pipe filter and installed on it drainage branch pipe is performed to interface plane of the cylindrical and cone parts of the hydrocyclone.

EFFECT: intensification of the water treatment process, increased time between washings of the pipe filter, increased quality of the pipe filter washing.
