Abstract
A clamping device for removably clamping a unit filter cell in position in a gas flow-through housing against a stationary gas flow-through frame structure includes a filter cell support tray selectively movable toward and away from the gas flow-through frame structure, thus, moving a unit filter cell supported on the tray into and out of contact, respectively, with the flow-through frame structure. The tray is moved through a plurality of pivotable levers which are each pivotably attached at one end to a stationary support and connected between its ends to the filter cell support tray. The levers are caused to pivot by means of bars which are connected to the other ends of the lever and are themselves mounted for selective linear movement along their longitudinal axes. Biasing means structurally associated with the pivotable levers cause a uniform clamping force to be applied by the filter support tray forcing the unit filter cell against the stationary support frame.
