Abstract: Cyclonic separator apparatus for extracting entrained lint particles from an effluent air stream prior to discharge into the atmosphere. A rotary filter is combined with a cyclonic separator of the type having a vertical settling chamber for separating relatively dense fiber product from airborne lint entrained in a product stream. The separator apparatus includes a housing forming an air stream inlet, a lint discharge outlet and a clean air outlet. A rotatable screen is interposed between the air stream inlet and the clean air outlet whereby the entrained lint is accumulated on the screen as the effluent air stream flows through the screen for discharge into the atmosphere. The accumulated lint deposit is presented to the lint discharge outlet as the screen turns. A first fan blower is coupled to the separator for inducing an upwardly moving inner vortex for entraining the airborne lint, and coupled to the filter inlet for discharging the entrained lint onto the rotatable screen.

Abstract: A filter system and method for extracting entrained lint particles from an effluent air stream prior to discharge into the atmosphere. The system and method are intended for use in combination with a cyclonic separator of the type having a vertical settling chamber for separating relatively dense fiber product from airborne lint entrained in a product stream. The filter system includes a housing forming an air stream inlet, a lint discharge outlet and a clean air outlet. A rotatable screen is interposed between the air stream inlet and the clean air outlet whereby the entrained lint is accumulated on the screen as the effluent air stream flows through the screen for discharge into the atmosphere.
