The filter chamber of the automatic pressure maintaining filter press is composed of two similar concave filter plates. When the filter cloth is on each filter plate, the advantages of the box filter press are high efficiency and the filter plate is relatively durable. The surface of the filter plate has a flat and rugged ball to support the filter cloth. There are through holes in the middle and corner of the filter plate. After assembly, a complete channel is formed, which can pass into the suspension, washing water and lead out the filtrate. Handle on both sides of the filter plate is supported on the cross beam, and the filter plate is compressed by the pressing device. Under the automatic compression of the oil cylinder, each filter plate is tightly closed, and a filter chamber is formed in the middle of the filter plate. Under the pressure of the feed pump, the automatic pressure maintaining filter will send the necessary filtered material and liquid to each filter chamber, filter the medium, and evacuate the solid and liquid. The filter residue is formed on the filter cloth until the filter cake is formed in the diffuse filter chamber. The filtrate passes through the filter cloth and flows along the filter plate groove to the lower outlet channel for joint drainage. After filtration, the filter residue can be washed with washing water. After washing, compressed air is also introduced to withdraw the remaining washing liquid. After the filtration, open the filter press to remove the filter cake, wash the filter cloth, and press the plate filter again to start the next filtration.
