CENTRIFUGAL SEPARATOR Russian patent published in 2017 - IPC B07B1/06 B07B1/46 B07B7/08 

FIELD: machine engineering.

SUBSTANCE: centrifugal separator comprises a frame, on which the drum is installed by the shaft, in the form of a truncated cone facing with its smaller base downward to the frustoconical, the working surface of which is provided with holes, a drum rotation drive and a vibrator for transferring fluctuations to the drum. The drum with the holes is formed as replaceable sieves. The vibrator, creating circular fluctuations, is made in the form of several, at least, three cylinders with sliding rods extending through their central hole and fixed in the elastic toroids filled with fluid and pneumo-controlling the reciprocating movement in the cylinders. The separator is provided with an additional perforated conical sieve. A conic grain distributor with impeller is inslalled at the drum bottom. The cyclone is connected with the reflector. Fluctuations are set at the frequency of 1-3 Hz.

EFFECT: increasing the efficiency of sieving, as well as the performance and quality of separation.
