Abstract
A filter bag support member for fastening a filter bag to an apertured bag header plate member disposed between the dirty gas inlet and the clean gas outlet of a filter bag housing comprising a flow-through venturi-like tube having one end releasably fastened to the plate member and a clamp at the other end receiving the filter bag in supporting sealed relation.
Claims10
A filter arrangement adapted to be secured to an apertured header plate disposed across a dirty gas stream between the dirty gas inlet and the clean gas outlet of a filter bag housing, comprising:
- a tubular filter;
- a filter bag support member integrally formed of a relatively rigid resilient material including a venturi-like tube section forming a venturi extending through the member;
- said member having a flexible collar portion at one end of the tube section for releasably securing the member to the apertured plate and an annular shoulder portion formed at the other end of the tube section extending into one end of the filter;
- and
- clamping means surrounding said one end of the filter and securing it to said shoulder portion in supporting sealing relation proximate the throat of the venturi extending through the member to provide a relatively unobstructed opening at said one end of the filter, thereby essentially minimizing pressure losses in the gas stream flowing through the filter.
