WATER TREATMENT 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, a filtering element 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, inlet, outlet and washing pipelines with relevant branch pipes and gate valves allowing for periodical change of operating mode: filtration of water suspension by the hydrocyclone and the filtering element, washing of the filtering element and treatment waste collector by return flow of the water suspension to the discharge system, the treatment waste collector with a quick-detachable cover and a tap. The filtering element consists of the cylindrical and conical parts conjugated in the plane of co-location of the hydrocyclone's cylindrical and conical parts. The sides of the filtering element's conical part are parallel to the sides of the hycrocyclone's conical part. The outlet hole of the feeding branch pipe in the hydrocyclone is made as a segment with the arc length l ≈ 3.1r, where r stands for the radius 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 hydrocyclone axis.

EFFECT: increased reliability and high quality of water treatment process.
