ABSTRACT:
Disclosed is a clamping means for securing filter bags in a bag filter device. The bag filter device has a filter chamber separated from a plenum chamber by means of a partition having openings therein through which the filter bags extend from the plenum chamber into the filter chamber. Gas to be filtered is passed into the filter chamber and flows through the walls of the filter bags from the outside to the inside thereof and thence into the plenum chamber prior to being discharged from the filter device as cleaned gas. The partition has a stationary shoulder surrounding each opening on the plenum chamber side. The open end or cuff of each filter bag is clamped between the shoulder and a clamping ring so as to secure the filter bag in the partition and to effect a seal which prevents leakage of unfiltered gas into the plenum chamber from the filter chamber. The seal is maintained by the influence of gravity or by a seating or force-applying means. Each clamping ring also serves as a support for a bag supporting frame disposed in each filter bag.
