Abstract: A filter press includes a frame, a power component and a plurality of filter plates driven by the power component to move to and fro along the frame to be at a pressure filtration position and an unloading position; a vibration cake unloading device includes a driving component and a vibration shaft longitudinally arranged; and protrusions are provided on an outer circumferential wall of the vibration shaft, when the filter plates are located at the unloading position, in the process that the driving component drives the vibration shaft to rotate around its own axis, the protrusions on the vibration shaft collide with the filter plate to assist in unloading. The vibration shaft has a simple structure, which can greatly reduce the cost, and the vibration cake unloading device is flexible in use. A filter press of spiral vibration cake unloading by pulling apart the filter plate twice is further provided.

Abstract: A high-efficiency filter press includes a filter plate for solid-liquid separation, a material pool for storing materials and transporting the materials to the filter plate, and a filtrate pool for storing filtrate flowing out of the filter plate, wherein the filter plate is provided with a feed hole, a first drain hole and a second drain hole, the material pool is in communication with the feed hole through a feed pipe, the first drain hole is in communication with the filtrate pool through a first drain pipe, the second drain hole is in communication with the filtrate pool through a second drain pipe. The filter press further includes a washing device which is configured to inject washing water into the first drain hole to allow the washing water to flow out from the second drain hole into the filtrate pool after flowing through the filter plate.

Abstract: A shaking device for filter plates of a filter press including a fixed support, a movable frame, a sleeve spring device, and a shaking rod. The fixed support includes a main beam and a support crossbeam. The movable frame includes a frame crossbeam and a vertical beam. The movable frame is disposed on the support crossbeam. One end of the sleeve spring device is attached to the frame crossbeam and the other end is attached to the shaking rod. The movable frame is driven by a gear motor. The shaking device further includes a cylinder assembly. The cylinder assembly is coaxially connected with the sleeve spring device and the shaking rod in a straight line. When the cylinder assembly acts on the shaking rod, the shaking rod shakes to separate and shakes a plurality of filter cloth rods of the filter plates to remove the filter cakes.
