Larox Finland PF32/32 M12 2 60

This filter press was used for proteins in chicken feed. The filtration elements (i.e. plates) of the PF filter are placed horizontally between two pressure plates. During filtration, the plate pack is pressed together, and the pack is opened to discharge the cake. The plate pack is opened and closed by means of hydraulic cylinders. The endless filter cloth zigzags between the filter plates, resulting in the filtered cake being formed on either side of the cloth. The filter cloth is thus automatically back flushed, and any particles adhering to it or lodged in the filter cloth from the previous filtration cycle are washed out when filtering on the reverse side of the cloth. The cloth transports the cakes from the filter, and simultaneously, the cloth is cleaned on both sides by high-pressure water sprays. The cloth moving device is driven by the hydraulic motor, which actuates the cloth drive roller. When opening and closing the filter plates, the tension of the filter cloth is maintained at a constant level by a simple cloth tensioning device. The cloth tensioning device does not operate when the plate pack is closed. Slurry is fed into sealed filter chambers through distribution piping. Wash water and compressed air are fed through the same pipe. The feed pipe is emptied through a drain valve upon completion of the feed pumping cycle. The operation of the filter is automatically controlled by the operating unit containing programmable logics and indicator lamps for all operations. The actuators of the automatically controlled valves are hydraulic and electromagnetic.
