ELECTRIC SEPARATOR WITH ROTATING ELECTRIC FIELD Russian patent published in 1995 - IPC

FIELD: agricultural engineering; seeds separation. SUBSTANCE: device has feeding bin with particle flow generation unit located below the feeding bin, particle flow generator, grounded cylindric casing filled with dielectric liquid and rotor mounted coaxially with respect to the cylindric casing on dielectric shaft having electrodes distributed along its generatrices, metal screen mounted between the casing and electrodes and electrically insulated from them, separation product receiving containers. The rotor and protection screen are made in form of truncated cones. The electrodes are conic and are distributed along the generatrices in checkered order. The protection screen is corrugated. Dry material from the feeding bin enters the space between the casing and protection screen through the flow generation unit. Nonhomogeneous electric field is formed due to electromotor rotating. Particle drawn with the field, move towards the grounded casing and enter into the receiving container. EFFECT: enhanced effectiveness in separating seeds. 2 dwg
