Abstract: A horizontally mounted filter cartridge dust collector includes a housing and a plurality of filter cartridges horizontally mounted in rows on a cartridge cradle disposed inside the housing for supporting the cartridges. The cartridge cradle includes a plurality of vertical risers and horizontal tubes attached between the risers and an inner wall of the housing separating the dirty and clean air plenums. A single access door facilitates inspection and servicing of all of the filter cartridges and the entire dirty air plenum. Pairs of studs attached to the inner wall mate with corresponding grooves in the cartridge end caps to precisely locate the horizontal and vertical positions of the cartridges. Clamping mechanisms are provided to compress and seal each row of cartridges to isolate the clean and dirty air plenums. Each clamping mechanism includes a rotatable shoe for isolating the cartridges and gasket seals from torque being applied to operate the clamping mechanism.

Abstract: A reverse blow-back dust collector utilizes a simplified top removal support arrangement for suspending bag, cage and nozzle assemblies from a tube sheet having plain mounting openings therein. The top removal support includes a collar spot welded to the cage and disposed in force fit engagement with a top fold region of the bag which contains an expansion clamping ring assembly having spaced beads which interlock the bag in sealed relation in its corresponding tube sheet opening. The support also includes a flange which overlies and seats on the upper bead for transmitting cage loads thru the support to the top side of the tube sheet. Ease of assembly and removal affords improved installation and servicing operations.
