HYDROCYCLON AND METHOD OF CONTROL OF HYDROCYCLON OPERATION Russian patent published in 2009 - IPC B04C5/00 B03B5/62 

FIELD: mechanics.

SUBSTANCE: invention is meant for separation of suspensions. Hydrocyclon includes cylinder-conic body structure with tangential intake and drain tubes, sand hole, cyclone chamber leakproofly connected to hydrocyclon and including cylinder-conic body structure with cone angle β₂=120°, containing tangential feeding tube located in cylindrical section and connected to water supply device and also containing sand tube located in conical section. Conical section of hydrocyclone is put down in cyclone chamber at depth equal to 3/4 of its cylinder part, ratio of area of sections of cyclone chamber and hydrocyclon is 1:(4÷5), ratio of area of sections of sand and feeding tubes of cyclone chamber and area of section of sand hole of hydrocyclon is 1:1.5:5.5 accordingly. Method of control of hydrocyclon operation by means of change of discharging in hydrocyclon body is characterised by the following: in core zone throughout the height of hydraulic cyclone rising flow of hydraulic fluid is formed due to supply to hydrocyclon sand hole of rising water flow which is formed by tangential supply of water to cylinder part of cyclone chamber.

EFFECT: enhancement of control efficiency, increase in productivity.
