An expressing plate assembly for an expression type filter press, wherein openings in the four corners of elastic expressing sheets placed on the opposite surfaces of a core plate are aligned with openings in the four corners of the core plate and in such condition the expressing sheets are secured to the core plate. Seating recesses in the form of circles concentric with the above-mentioned openings are formed in the opposite surfaces of the core plate, while raised portions adapted to tightly fit in the recesses are formed on the expressing sheets. Clamping seating rings are fitted in recesses on the outer side of the recesses. Each clamping seating ring is formed with grooves for filtrate.

Expressing plate assembly for filter press

An apparatus comprising a pair of reciprocally movable carriers each provided with a drive dog and a stop dog tiltably pivoted to the carrier and biased toward a tilted position in the direction opposite to a direction of transport of filter plates, a stopper for preventing the drive dog positioned toward the opposite direction from tilting toward that direction and releasing the drive dog from its prevented position, another stopper for preventing the stop dog from tilting toward the transport direction, and a freely movable member pushable by the drive dog to raise the stop dog when the drive dog tilts toward the transport direction. After all the filter plates have been transported, the stopper for the drive dog is manually or automatically operated to release the drive dog toward its tilted position, and the direction of the travel of the carrier is reversed, causing the carrier to return free of interference with the group of transported filter plates toward a standby position, where the carrier is stopped with the drive dog held in its raised position by the stopper.
