HOSE FILTER Russian patent published in 1995 - IPC

FIELD: recuperation of powder paints. SUBSTANCE: dust separator is constructed as an arc interposed between hopper and filtering members, coupled with the inlet passage through inertial radius, and inclined in the direction opposite to the direction towards the inlet passage. The side walls of the arc are provided with openings. The area of the openings increases in the direction opposite to the direction towards the inlet passage. The deflectors are mounted above the openings. Deflecting plates are inclined to the arc surface. A portion of powder is extracted from air suspension flow by the inertial radius. The dust separator also removes a portion of the powder and distributes the flow over the filter cross-section. EFFECT: enhanced quality of cleaning. 4 cl, 2 dwg
