Bag filter rim system |
摘要 |
A filter assembly (10) with a filter housing (12) and a bag-type filter element (14). A collar (36) is disposed inside the housing below an opening (42) through which a process stream is introduced into the filter assembly. The filter element includes a filter bag (70) to which a sealing ring (72) is attached. The sealing ring is formed to define a channel (84) in which the collar is seated. The sealing ring also has a lip (86) that snap secures against a complementary stepped surface (60) formed around the collar. A gasket (85) attached to the sealing ring forms a liquid-tight barrier between the collar and the sealing ring. The collar is also formed with a boss (62). The sealing ring defines a alignment notch (88). In order to seal the filter element in place, boss (62) must seat in alignment notch (88); this ensures that when the filter element is secured in place, it is properly aligned with the other components of the filter assembly.
