LINEAR ASYNCHRONOUS ELECTRIC DRIVE FOR A VIBRATION CENTRIFUGAL SEPARATOR Russian patent published in 2021 - IPC B07B1/42 B07B1/26 B07B9/00 

FIELD: separation.

SUBSTANCE: invention relates to separators intended for separating primarily grain materials, and can be used in milling, chemical, and other branches of industry. A linear asynchronous electric drive for a vibration centrifugal separator consisting of a body, a working element, a rotary motion drive of the working element from a rotation engine and a vibration drive of the working element in the vertical plane from a flat linear asynchronous electric engine, the inductors whereof are rigidly fixed on the base, and the rotor thereof in the form of a ring with symmetrical through holes is movable and spring-loaded in the vertical plane, made of metal with high electrical conductivity, and rigidly connected with the working element. Arc-shaped symmetrical plates are located in the through symmetrical holes of the ring, interconnected by guides spring-loaded relative to the axial shaft of the ring, configured to move in the vertical plane. The arc-shaped plates are made of the same material as the ring.

EFFECT: increase in the power characteristics of the drive for increasing the efficiency of separation.
