Abstract
Disclosed is a filter assembly for use in a baghouse having a cell plate provided with openings. The filter assembly includes a 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 has a longitudinally extended portion that structurally supports the filter bag. The locking ring is integrally fixed to the supporting cage and locks an arrangement of the filter bag, collar and cage in place. The locking ring also can include a venturi affixed thereto to assist in filtering and cleaning operations.
