A filter press that is easy for mud cake to drop and the upper end is not easy to leak

Abstract

The invention discloses a press filter plate having convenience in falling out of sludge cake and being not liable to cause water leakage on the upper end. The press filter plate includes an air cylinder fixing board, a movable push plate, a plurality of filter plate bodies, a central shaft, and a position limiting stopping plate. The central shaft is welded to the middle part of the left end of the air cylinder fixing board. The left end of the central shaft is sleeved fixedly with the position limiting stopping plate. When an air cylinder arranged between adjacent filter plate bodies is opened, an elastic reset plate can drive a rubber push plate connection rod to move down, then a rubber push plate drives a sludge cake, between the filter plate bodies, to fall off, so that the press filter plate can assists the sludge cake to fall off and avoid adhesion of the sludge cake onto the filter plate bodies; in the invention, when the adjacent filter plate bodies are pressed on each other,the rubber push plate can seal the gap between the top ends of the adjacent filter plate bodies, so that leakage of sludge water from the upper ends of the adjacent filter plate bodies is prevented,and the peripheries of the filter plate bodies are not liable to be polluted. The press filter plate is easy to clean.

Description

technical field [0001] The invention relates to the technical field of filter plates of filter presses, in particular to a filter press which is convenient for mud cake to drop and whose upper end is not easy to leak water. Background technique [0002] The filter press uses a special filter medium to apply a certain pressure on the object to make the liquid dialysis out. It is a kind of mechanical equipment commonly used for solid-liquid separation. It was used in chemical production at the beginning of the 18th century, and is still widely used in chemical, pharmaceutical, metallurgy, dyestuff, food, brewing, ceramics and environmental protection industries. The filter plate has stable performance, convenient operation, safety and labor saving; Seamless steel pipe processing, precision casting of plastic-steel filter plates, high temperature resistance, high pressure, and durability, but the existing filter plates for filter presses still have the following disadvantages i...

AI Technical Summary

Problems solved by technology

[0003] 1. In the existing filter plates for filter presses, the mud cake between adjacent filter plates sometimes adheres to the filter plates when it falls, and is not easy to fall off, which reduces the corresponding working efficiency of the filter press;

[0004] 2. In the existing filter plate for filter press, when the filter plate is actually pressed, the mud water will also flow out from the upper end of the filter plate, and then the upper end of the filter plate will also be contaminated with mud, which is often cleaned directly On both sides of the filter plate, the mud on the top of the filter plate is not easy to clean, inconvenient to use, and reduces the efficiency of solid-liquid separation
