CENTRIFUGE WITH UPPER LOCATION OF VORTEX HYDRAULIC DRIVE AND OPEN CASE Russian patent published in 2022 - IPC B04B9/14 B04B1/02 B04B3/00 

FIELD: separation.

SUBSTANCE: invention relates to device intended for separation of liquid non-homogenous systems, using centrifugal forces. The centrifuge consists of a support disc with an axis fixed under it and a rotor installed on the axis in bearings, including a column and a coil fixed with a nut. A liquid supply fitting is attached to the support disc from above, and a vortex chamber of a guiding device of a hydraulic drive turbine with several tangential input channels is attached from below. Liquid passage from the fitting to the vortex chamber is performed through holes in the support disc, from top to bottom. A working wheel of the turbine of a conical shape with radial channels, fixed with a conical flange, is installed outside the rotor column, under the guiding device. Holes for liquid input from a turbine stage to a separating cavity of the rotor are made opposite each channel of the wheel, in the bottom of the column. Output of purified liquid from the rotor is carried out through radial and central channels in a lower part of the column, directly to a tank. Liquid leakages through a cylindrical seal of the turbine stage are removed to sides down, as well as to a free space of the tank. Due to the absence of a centrifuge case, they do not enter the rotor, do not create an air-drop medium in a near-rotor space, and, consequently, do not exert additional resistance to its rotation.

EFFECT: increase in the efficiency of liquid purification due to an increase in a rotational frequency of the rotor, provided by reduction in a rotation resistance moment, as well as simplification of a centrifuge structure.
