ADJUSTABLE VACUUM PAN ASSEMBLIES FOR BELT FILTERS

摘要

An adjustable vacuum pan assembly for a belt filter is disclosed. The adjustable vacuum pan assembly comprises an arm configured to be attached to a frame portion of the filter, a vacuum pan adjustably connected to the arm, and a cam operatively coupled to the arm. The cam is rotatable with respect to the arm and has a peripheral surface which contacts a portion of the vacuum pan. The assembly further comprises a locking member which serves to hold the cam against rotation with respect to the arm. Varying an angular rotational position of the cam effectively varies a spacing between the vacuum pan and the arm, thereby providing an amount of misalignment compensation therebetween. Retrofit kits for a preexisting conventional filter and methods of providing increased adjustability to a filter are also disclosed.
