CENTRIFUGE WITH VORTEX DRIVE AND ADJUSTABLE FLOW OF CLEANED LIQUID Russian patent published in 2021 - IPC B04B1/00 B04B1/06 B04B9/06 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to devices designed for the separation of liquid inhomogeneous systems using centrifugal forces. The centrifuge consists of a housing and a rotor, including a column and a drum. At the base of the housing there is a vortex chamber of the guide device of the hydraulic drive turbine with tangential channels. The lower spike of the column is located in its central non-flowing zone. A conical impeller of a radial-axial centrifugal turbine with radial channels is attached to the bottom of the column by a flange. At the periphery of the impeller, an annular cavity is formed at the exit from its channels. It is connected to the separating cavity of the rotor by a number of holes in the bottom of the column, as well as to the central channel in the lower spike of the column by sector cavities made at the end of the impeller. Due to this, the liquid at the outlet of the turbine stage is divided into two streams. One stream is cleaned in the rotor and removed from the centrifuge through its upper support. Its flow rate is regulated by a throttle. The other stream is drained back into the tank through the central channel in the lower spike of the column and the lower support.

EFFECT: invention makes it possible to increase the efficiency of separation by providing the possibility of regulating the flow of the cleaned liquid with a constant operating mode of the vortex hydraulic drive.
