A JET-TYPE CONICAL HYDROCYCLONE Russian patent published in 2005 - IPC

FIELD: separation of suspensions, emulsions and purification of sewage.

SUBSTANCE: the invention is intended for separation of suspensions, emulsions and for purification of sewage in the field of the centrifugal forces. The jet conical hydrocyclone for separation of suspensions, emulsions and for purification of sewage from finely dispersed impurities of solid and liquid phases contains a cage with an inlet branch-pipe tangentially inclined in respect to the axis of the jet conical hydrocyclone, an upper draining branch-pipe, a chamber - collector of a thickened fraction with an outlet branch-pipe and a displacer. Inside the body there is an insert with a screw-type rectangular channel passing from the upper inlet branch-pipe up to the chamber - collector of a thickened fraction. The displacer is made cylindrical. The outlet cross-section of the chamber - collector thickened fraction channel is adjusted by a screw-type motion of the displacer, on the cylindrical part of which there is a screw-type conical element, which is meshing with crew-type channel of the insert. The body is conical cage is executed taper, the angle of inclination of the inlet branch-pipe makes 95-97° in respect to the axis of the jet conical hydrocyclone. In the upper draining branch-pipe there is a cartridge with the internal conical element forming an external conical ring-type drain channel and an internal conical axial draining channel. The technical result of the invention is expansion of the range of use of the jet conical hydrocyclone in the field of on technological and physico-chemical initial parameters of the separated and purified sewage.

EFFECT: the invention ensures expansion of the range of the jet conical hydrocyclone technological and physico-chemical initial parameters.
