我院于1982年研制了XAZ40—810/30型自动厢式压滤机,在此基础上,又发展了XM AGZ(20～60)/800型隔膜自动厢式压滤机和XM A(20～60)/800型厢式压滤机。现将它们的设计特点和应用情况介绍如下。一、聚丙烯厢式压滤机的设计特点 1.滤室结构压滤机按滤室的结构分为板框式和厢式。板框式的滤饼厚度均匀、洗涤效果好,但滤饼的排出困难。厢式的滤饼容易脱落,且因无滤框,构件单一,结构紧凑,尺寸小。另外,厢式耐压可高达1.5MPa,而板框式过滤压力仅0.6MPa;厢式进料口多在中间,进料孔较大,因而进料和过滤速度都较快。因此本设计采用厢式滤板,其结构见图1。

In 1982, our institute developed the XAZ40-810 / 30 automatic box filter press. On the basis of this, XM AGZ (20 ~ 60) / 800 automatic membrane filter press and XM A (20 ~ 60) / 800 type box filter press. Now their design features and applications are described below. First, the design features of polypropylene box filter press 1. Filter chamber structure Filter press chamber structure is divided into plate frame and van. Plate-type filter cake thickness uniform, good washing effect, but difficult to discharge the filter cake. Van cake easy to fall off, and because of no filter box, a single component, compact structure, small size. In addition, the van pressure can be as high as 1.5MPa, while the plate and frame filter pressure is only 0.6MPa; van feed more in the middle, the feed hole is larger, so feed and filter speed are faster. Therefore, the design uses box filter plate, the structure shown in Figure 1.
