Rotary filter for fiber product

A rotary filter for use in a processing system for fiber product or the like for removing airborne lint from an air stream, agglomerating the lint and delivering it to a discharge outlet for further processing, comprising, in combination:

• settling means having a housing enclosing a settling chamber and having an air stream inlet, a lint discharge outlet and a clean air outlet;
• a rotor shaft mounted for rotation within said chamber;
• a rotatable screen drum mounted on said rotor shaft for rotation within the settling chamber and interposed between the air stream inlet and the clean air outlet whereby the entrained lint is accumulated on the screen as the air stream flows through the screen and out of the clean air outlet, and whereby the accumulated lint deposit is presented to the lint discharge outlet as the screen turns;
• means coupled to said settling chamber for inducing the flow of air through the air stream inlet and out of the clean air outlet;
• means forming a rotatable seal between said drum and said settling chamber housing;
• means coupled to said drum for removing accumulated lint from said screen, said lint removing means including an air distribution bar disposed within said drum, said distribution bar having a plurality of air jet nozzles for directing pressurized air through said screen;
• means coupled in fluid communication with said distribution bar for conveying pressurized air to said bar from an external source, said pressurized air means including a tube defining an air supply plenum disposed about said rotor shaft;
• means defining a rotary fluid seal between said shaft and said plenum tube;
• and,
• a stand-off conduit mechanically supporting said distribution bar adjacent said screen drum and connecting said distribution bar in fluid communication with said air supply plenum.
