板框压滤机由交替排列的滤板和滤框构成一组滤室。滤板的表面有沟槽，其bai凸出部位用以支撑滤布。滤框和滤板的边角上有通孔du，组装后构成完整的通道，能通入 悬浮液、洗涤水和引出滤液。板、框两侧各有把手支托在横梁上，由压紧装置压紧板、框。板、框之间的zhi滤布起密封垫片的作用。由供料 泵 将悬浮液压入滤室，在滤 布上dao形成滤渣，直至充满滤室。滤液穿过滤布并沿滤板沟槽流至板框边角通道回，集中排出。过滤完毕，可通入清洗涤水洗涤滤渣。洗涤后，有时还通入压缩空气，除 去剩余的洗涤液。随后打开压滤机卸除滤渣，清洗滤布，重新压紧板、框，开始下一工作答循环。

　　The plate and frame filter press is composed of filter plates and filter frames arranged alternately to form a group of filter chambers. A groove is arranged on the surface of the filter plate, and the protruding part of the Bai is used to support the filter cloth. There is a through-hole DU on the corner of the filter frame and the filter plate. After assembly, it forms a complete channel, which can pass into the suspension, the washing water and the filtrate. The handle on both sides of the plate and frame is supported on the beam, and the plate and frame are compressed by the pressing device. The ZH filter cloth between the plate and the frame acts as a sealing gasket. The suspension hydraulic pressure is put into the filter chamber by the feed pump, and the Dao on the filter cloth forms the filter residue until the filter chamber is filled. The filtrate passes through the filter cloth and flows along the filter plate groove to the edge and corner channel of the plate frame for return and centralized discharge. After filtration, the filter residue can be washed with washing water. After washing, compressed air is sometimes introduced to remove the remaining washing liquid. Then open the filter press to remove the filter residue, clean the filter cloth, press the plate and frame again, and start the next work cycle.
