Pressure filter

Abstract

The invention relates to a pressure filter machine, which is an improvement on the filter press. The invention provides a filter press which not only works continuously and automatically, but also can increase the filtration pressure and is convenient for vehicle-mounted movement. The present invention has a cylinder (1), has shaft (24) in its center, and rotating plate (14) is arranged on the shaft and rotates clockwise and anticlockwise alternately with the shaft at the same angle, left dividing plate (9), right dividing plate ( 7) It can move up and down, and the filtered filter cake can be moved from the partition to be emptied into fan-shaped holes, and discharged from the cylinder (1), and the filtrate passes through the rotating plate filter (36) and the rotating plate (14). The clapboard filter screen (37) on the clapboard, the sump (35), the left drain pipe (8), and the right drain pipe (6) are discharged; the filtrate is discharged by the pump (44) through the feed left valve ( 39), the feed right valve (40), the feed left pipe (11) feed right pipe (5), and the pressure limiting valve (38) enters the filter chamber. The present invention can continuously and automatically perform pressure filtration. In addition to the pump pressure of the original technology, the filtration pressure also increases due to the rotation of the rotating plate (14) to reduce the volume of the filter chamber, thereby saving labor, reducing labor intensity and improving automation. In addition, it also improves the filtration efficiency and filtration quality.

Description

technical field [0001] The invention relates to a pressure filter machine, which is an improvement on the filter press Background technique [0002] The existing filter presses are divided into plate type and belt type. The plate filter press has a set of filter plates with grooves, and filter cloth is sandwiched between the filter plates. The stacked filter plates are pressed tightly by a hydraulic mechanism. Each filter plate is respectively opened for inputting the mixed liquid to be filtered And the holes for discharging the filtrate. After filtering, the filter plate must be loosened in order to remove the filter cake and clean the filter cloth. Therefore, the work is carried out intermittently and discontinuously, requiring manual operation, and the labor intensity is high. The belt filter press uses the pressure between the filter belt and the roller or pressure belt to filter the solid-liquid mixture on the filter belt. Although the filtration is continuous, since...

AI Technical Summary

Problems solved by technology

Although the filtration is continuous, since both sides of the filter belt are open, the filtration pressure should not be too high, lest the material to be filtered be extruded from both sides of the filter belt, so that a very dry filter cake cannot be obtained, and the filtering effect is not ideal
