Abstract

See full text

An apparatus and method for cleaning a drum filter medium are disclosed. Air with entrained particulate matter, e.g., from a papermaking process, flows through a filter medium positioned along the perforated circumferential surface of a rotating drum. At least some of the particulate matter is caught on or in the filter medium. A set of suction nozzles provided proximate to the surface of the filter medium is provided to draw the particulate matter off of the filter medium. A complementary set of compressed air nozzles simultaneously delivers compressed air to drive particulate matter off of the filter medium and into the suction nozzles. This cleans the filter medium in situ and extends its useful life.
