CROSS-FLOW-THROUGH ROTARY DUST-CATCHER Russian patent published in 2007 - IPC B01D45/14 

FIELD: agriculture; gas-producing industry; medical equipment industry; other branches of industry; devices for dry purification of the air and the gases from the dust particles.

SUBSTANCE: the invention is pertaining to the devices for dry purification of the air and the gases from the dust particles as well as to purification of the waste air in the systems of aspiration of grain-purification machines, devices of an aspiration of the grain-purification machines, aggregates as well as the complexes of the post-harvesting treatment of the grain. The cross-flow-through rotary dust-catcher contains the body, the installed in it revolving rotor, the inlet and outlet fitting pipes, the dust container. The rotor is made in the form of the wheel with the plane blades curved along their length and mounted on the internal diameter at the angle of β_i=9O±5°, the outer ends of which are bent back by the angle of 20...30° to the radius-vector of the rotor. The plane blades form the channels for relocation of the air in the transversal direction. On the lateral sides the rotor is covered by the solid disks. The inlet and outlet fitting pipes are mounted on the body facing each other and are communicating among themselves by means of the channels of the rotor. The internal diameter of the rotor is equal to 0.6...0.7 of its external diameter, the angle of the arc of the air inlet into the rotor - 170°...190°, the angle of the arc of the air outlet of the rotor - 90°...110°. The gaps between the rotor and the inlet edge of an outlet fitting pipe and the inlet and the outlet edges of the body - 0.01...0.02 of the external diameter of the rotor. The depth of the dust container is no less than 3 external diameters of the rotor. The technical result of the invention is the increased efficiency of the purification.

EFFECT: the invention ensures the increased efficiency of the purification.
