For an inside to outside dust collector, a self tensioning device for bag filters for connecting the upper end of a fabric sleeve filter to an overhead support. The device includes a modified double draw bar spring assembly interposed between the overhead support of the baghouse and the upper end of the bag filter. Prior to installation, the spring is compressed and captured by a retainer member. After installation, the retainer member may be removed and the spring flexed to appropriately tension the filter sleeve and to permit controlled flexure during cycling from a filtering to a cleaning operation.

Tensioning device for bag filters

For an inside to outside dust collector, a tensioning device for bag filters for connecting the upper end of a fabric sleeve filter to an overhead support. The device includes a modified double draw bar spring assembly having a conical spring therein interposed between the overhead support of the baghouse and the upper end of the bag filter. A retainer member engaging the large end of the conical spring receives therethrough the first and second draw bars to prevent binding of the spring assembly and to translate the conical spring force to uniform linear forces acting through the first and second draw bars to appropriately tension the filter sleeve and to permit controlled flexure during cycling from a filtering to a cleaning operation.

Filter bag tensioning spacer

Installation and maintenance equipment to tension a fabric sleeve filter supported from a bag support frame in a baghouse by a retainer rod and a tensioning spring. A tensioning tool is configured to be removably coupled to the retainer rod while compressing the tensioning spring to pull taut the fabric sleeve. A speed control regulates the speed at which the spring is compressed and a regulator determines the force applied to the spring. A pneumatic, hydraulic or electromechanical power source supplies the tensioning force.

Method and apparatus for tensioning bag filters

Installation and maintenance equipment to tension a fabric sleeve filter supported from a bag support frame in a baghouse by a retainer rod and a tensioning spring. A pneumatic tool is configured to be removably coupled to the retainer rod while compressing the tensioning spring to pull taut the fabric sleeve. A flow control valve regulates the speed at which the spring is compressed and a pressure regulator determines the force applied to the spring.

For an inside to outside dust collector, a self tensioning bag retainer for connecting the upper end of a fabric sleeve filter to an overhead support. For preinstallation of the filter assembly, a compressed tensioning spring is retained from movement by a pin member to facilitate ease of installation. With the pin member removed, however, the spring acts upwardly against a retainer cap to appropriately tension the sleeve filter and to permit controlled flexure during cycling from a filtering to a cleaning operation.
