PNEUMATIC SCREEN RADIAL SEPARATOR Russian patent published in 2009 - IPC B07B9/02 

FIELD: mechanics.

SUBSTANCE: invention relates to engineering means of separation for bulk materials. The invention is aimed at separation of bulk materials to fractions based on their external physical and mechanical features. The invention may be used for post-harvest handling of grain seeds in order to separate main grain seeds from weed and other foreign weeds and to separate multi-componential bulk materials in other industries. The radial separator with pneumatic screen is provided with silo fixed to the separator frame. The silo is with circular feeder installed on the top of conical dispenser. The inverse cone is under the above-mentioned dispenser and rests upon the central vertical channel. Conical screen is provided with shell and co-axially and hinged connected with the frame so that it can make vibratory movements around vertical axis. Collecting inverse cone is located under the screen and tightly connected with the upper edge of external wall of circular pneumo-separating vertical channel. Elastic cylindrical strips are fixed to the upper part of the circular pneumo-separating channel on its inner and outer walls. The upper and lower ends of the said strips are tightly connected with walls. Pipelines are inserted in the space between walls and strips. The pipelines are intended for gas and liquid supply. Conical dispenser is provided with screen-like section, which covers 20 to 80% of the whole length of cone dispenser surface.

EFFECT: improved effectiveness of particles separation by size, aerodynamic properties, density, surface state, ratio of dimensions and other features; improved quality of multi-component bulk materials cleaning.
