Method and apparatus for producing fiber product

摘要

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. 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. A second fan blower is coupled to the lint discharge port for creating a suction force which cleans the accumulated lint deposit from the rotating screen, and connected to the separator for returning the lint deposit to the settling chamber of the separator for recycling. In a preferred embodiment, the rotating screen comprises a drum having a cylindrical screen surface for accumulating a lint deposit, with one end of the drum being covered by a screen, and the other end being open for discharge of the effluent air stream into the atmosphere.
