  • Patent number: 8857626
    Abstract: An adjustable vacuum pan assembly [190] for a belt filter [900] is disclosed. The adjustable vacuum pan assembly [190] comprises an arm [140] configured to be attached to a frame portion [930] of the filter [900], a vacuum pan [150] adjustably connected to the arm [140], and a cam [170] operatively coupled to the arm [140]. The cam [170] is rotatable with respect to the arm [140] and has a peripheral surface which contacts a portion [157] of the vacuum pan [150]. The assembly [190] further comprises a locking member [169] which serves to hold the cam [170] against rotation with respect to the arm [140]. Varying an angular rotational position of the cam [170] effectively varies a spacing between the vacuum pan [150] and the arm [140], thereby providing an amount of misalignment compensation therebetween. Retrofit kits for a preexisting conventional filter [900] and methods of providing increased adjustability to a filter [900] are also disclosed.
