  • Snap-in filter bag assembly for bottom loading in dust collector
    Patent number: 5308369
    Abstract: A cylindrical filter bag including a wire mesh cage is provided with an access opening in the cage proximate to the open end of the filter bag. A resilient snap band is provided around the outer circumference of the cylindrical filter bag. The snap band includes a pair of felt rings formed around the band and an annular groove between the rings. The snap band thus provided can be depressed into the access opening in the wire mesh cage to allow the filter bag to be readily positioned in an airtight manner within a circular hole provided in the tube sheet of a dust collector. The hole in the tube sheet is provided with a collar having a radially extended flange portion that is attached to the top surface of the tube sheet to center the collar above the hole. The wire mesh cage of the filter bag is further provided with a reinforcing sleeve that mates with the tube sheet collar, and a venturi that is positioned concentrically within the sleeve.
