Variable length bag cage

A filter for use within a baghouse for filtering particulate material from fluid flowing through the filter, the filter to be supported by a tubesheet of the baghouse, the filter including:

• an elongate bag having an open end adapted to be disposed adjacent to the tubesheet and an encircling sidewall extending from the open end to a distal end of the bag, the sidewall permitting passage of fluid there through so that the fluid may pass through the bag and blocking passage of particulate material;
• an elongate cage located within and supporting the bag and having a variable effective length, the cage including structure inhibiting movement of the cage relative to the tubesheet;
• and
• cage-associated structure for increasing the effective length of the cage to maintain the sidewall to be taut adjacent the cage.

A baghouse assembly including:

• a housing including a dirty fluid chamber and a clean fluid chamber separated by a tubesheet, the tubesheet having at least one aperture there through;
• and
• a filter for filtering particulate material from fluid flowing through the filter, the filter to be supported by the tubesheet, the filter including:
• an elongate bag having an open end adapted to be disposed adjacent to the tubesheet and an encircling sidewall extending from the open end to a distal end of the bag, the sidewall permitting passage of fluid there through so that the fluid may pass through the bag and blocking passage of particulate material;
• an elongate cage located within and supporting the bag and having a variable effective length;
