ABSTRACT:
An attachment structure for attaching a small-diameter dust-collecting filter cartridge to the underside of a baghouse tube sheet comprises two bag cups are coaxially aligned but inverted with respect to each other. The upper bag cup has an internal flange at its upper end. The lower bag cup has an internal flange at its lower end. The other ends of the two bag cups face each other in spaced-apart relation. An external circumferential groove is provided near each of the other ends.
The internal flange of the upper bag cup is riveted to the underside of the tube sheet. The internal flange of the lower bag cup is bonded to an upper collar of the filter cartridge. A single sleeve of heavy rigid rubber material embraces the spaced-apart grooved other ends of the bag cups. The sleeve has a pair of spaced-apart annular internal beads which are received within the circumferential grooves of the two bag cups. A pair of band clamps lock the annular beads in the circumferential grooves, thereby locking the two bag cups together.
