GAS DISTRIBUTING GRID OF AERODYNAMIC CHUTE FOR DRYING BULK MATERIALS Russian patent published in 2001 - IPC

FIELD: bulk granular material drying equipment. SUBSTANCE: gas distributing grid has chute with sides and bottom composed of plates which are arranged so as to define slitlike gaps. Each plate defining bottom is bent down so as to form curved surface, and is made in the form of side built-up edge at side opposed to curved surface. Each plate defining sides is bent inward of chute at one edge for forming arced part and at other edge for forming built-up portion, respectively. Planks and sides are connected to bottom for forming air supply channel. Drying agent (air) is supplied via air supplying channel via arced slitlike channels to material to be dried so as to form uniformly fluidized layer movable at predetermined direction. Gas distributing grid may be used for intensified drying of fluidized grain layer in grain driers in the process of conveying grain by creating channels in grid preventing falling of grain under grid and imparting direction to drying agent (air) at bottom portion at acute angle to movable material, and in lengthwise direction at side portions. EFFECT: increased efficiency, wider operational capabilities and improved quality of dried bulk material. 3 dwg
