AIR SEPARATOR Russian patent published in 2003 - IPC

FIELD: agricultural engineering, in particular, cleaning equipment for grain and grain processing product. SUBSTANCE: grain comprising light contaminants is fed into separating channel equipped with movable wall. Grain is discharged under gravity through lower part of separating channel. Light contaminants are sped up together with air in speeding up channel and separated by means of centrifugal air and light product separator equipped with settling chamber. Light product is delivered from settling chamber via discharge device. Air is returned through fan and air return channel for recirculation. Centrifugal air and light product separator is turned for angle of 90 deg with respect to separating channel provided with movable wall. Speeding up channel and air returning channel are made in the form of single branch pipe. Such construction allows separator dimensions to be reduced. EFFECT: increased efficiency and enhanced reliability in operation. 3 dwg
