ABSTRACT:
Apparatus for filtering air discharged from a cotton gin, so as to minimize the likelihood of contamination of the ambient atmosphere by airborne particulate waste from the gin. The exhaust air from the gin is fed to a housing containing, as initial filtering means, an inertial classifier in which relatively large particulate matter is screened from the air and dropped by gravity to the bottom of the housing below the inertial classifier screen, where it is collected and discharged, preferably by a compacting screw conveyor. A major part of the air along with entrained relatively smaller particles of foreign matter is passed through the inertial classifier screen. The filtered air passing through the inertial classifier screen, with the relatively smaller particles of foreign matter entrained therein and the particulate matter thrown up by the dropping of the initially screened relatively large particulate matter, is passed through a secondary filter, a rotary drum filter serving to remove the relatively smaller particulate matter, leaving relatively clean air for discharge from the housing to the atmosphere.
