ABSTRACT:
A compact, self-cleaning, cabinet, dust collector is provided. The collector housing is a single-piece, molded unit having recessed areas and a molded air inlet. Entering dust-laden air is directed into two flows in a passageway surrounding a suspended, flexible, pleated filter element. An inner wall of the passageway contains a precleaner upstream from the filter element. A collector ramp, at the bottom of the passageway, directs pre-cleaned matter to a removable hopper. A fan, supported above the open upper end of the filter element draws air through the collector. A fan motor is isolated from the housing interior in one of the recessed areas of the housing. To gain access to the filter element the fan is rotated upwardly and away from the filter element. To prevent the pleats of the element from collapsing, hot-melt spacers are provided on the pleat surfaces. The element is flex-cleaned by a rotatable mechanism located beneath and adjacent the bottom closed end of the element. The mechanism causes a lifting and twisting of the element and includes an isolated motor, a rotatable arm with wiper blades, and ramp lugs on the bottom end of the filter element. The released dust is swept into the hopper by the wiper blades. A removable double-walled cover is secured over the fan. Filtered air is released from the collector through louvered openings in the cover. Transistor logic and various sensors are used to control the operation of the collector.
