ABSTRACT:
A plate filter comprises a plurality of shiftable filter plates and first and second deflecting rolls carried on opposite sides of each filter plate. The axes of consecutive first deflecting rolls lie alternatingly in a first plane and in a second plane spaced from one another. A filter cloth is guided in a zigzag course between consecutive filter plates by the first and second deflecting rolls. A first sprocket is affixed to each first deflecting roll and a second sprocket is mounted on each first deflecting roll for free idling rotation. First and second spaced, elongated, oppositely driven chains are respectively trained in a zigzag course in an alternating sequence about first and second sprockets of first deflecting rolls belonging to consecutive filter plates. The first and second chains are in meshing relationship with the first and second sprockets about which the chains are consecutively trained. The diameter of the first and second sprockets and the distance between the first and second planes are dimensioned for varying the magnitude of a loop angle represented by an arc along which the first and second chains are in engagement with respective first and second sprockets to compensate for length variations of the first and second chains upon shifting motion of the filter plates relative to one another.
