ABSTRACT:
A pneumatic dust collecting system for a fiber processing machine which includes a tank having a chamber therein within which separate streams of dust and reusable fibrous material are received and collected. The tank contains an air expansion compartment adjacent the receiving and collecting chamber and shares a common wall which functions as a filter. A blower assembly is positioned within the tank and is adapted to apply suction to the air expansion compartment so as to draw air from the chamber via the compartment and to force a stream of pressurized air from the tank to an air pressure stabilizing chamber located adjacent one end of the fiber processing machine. An air manifold having a plurality of spaced discharge nozzles is connected to the air pressure stabilizing chamber and is adapted to discharge a blanket of air beneath the machine. A waste material receiving receptacle is positioned adjacent the other end of the fiber processing machine and has an inlet adapted to receive a stream of air, dust and some fibrous material blown into same by the plurality of nozzles. The thus received stream of air, dust and fibrous particles is sucked into the receiving and collecting chamber of the tank. A separate conduit system draws reusable fibers from the fiber processing machine into a separate section of the receiving and collecting chamber of the tank. The various elements constitute an effectively closed recirculating system.
