Abstract
Disclosed is a filter assembly for use in a baghouse having a cell plate provided with openings. The filter assembly includes a molded collar, filter bag, tubular supporting cage and locking ring. The filter bag filters particulate material and extends from below the cell plate. The collar supports the filter bag and has a longitudinally extended portion and a flange portion. The longitudinally extended portion is affixed to the filter bag below the cell plate, while the flange portion extends along the cell plate as a rim above a respective opening. The collar acts as a gasket to seal a respective opening in the cell plate. The tubular supporting cage structurally supports the filter bag and has a longitudinally extended portion and a collar portion. The longitudinally extended portion supports the filter bag, while the collar portion partially overlaps the flange portion of the collar. The locking ring locks the filter bag, collar and cage in place. The locking ring can include a venturi affixed thereto to assist in filtering and cleaning operations.
