摘要： A stack of flat plates consisting of rectangular frames spanned by filter cloth, normally held together under pressure, is overlain by a rail extending lengthwise of the stack and carrying a transverse beam on which a carriage supports a cleaning unit introduceable from the side into the space between two separated filter plates. The unit comprises a pair of horizontal or vertical spray tubes, each extending over the full width or height of the filter cloth, which are vertically or horizontally movable with the aid of a pair of guide rollers riding on opposide edge portions of the frame when driven apart by a fluidoperated expander. The correct positioning of the beam with reference to the separated filter plates can be ascertained by a centering device adapted to be lowered into the intervening space, this device including two spreadable arms terminating in respective sensing rollers.
