Plate filter press

Abstract

The invention discloses a plate filter press which comprises a thrust plate, a filter pressing plate (04), a plate taking trolley (03) and a filter cloth which is deformed after being filled with fluid with pressure, when the plate filter press enters an unloading state, a fluid temporary storage cavity (06) is expanded, so that the filter cloth is deformed, and the contact area of the filter cloth and a solid material subjected to filter pressing is gradually reduced, falling and separation of solid matters from the filter cloth under the action of gravity after filter pressing is finished are facilitated, fluid with certain pressure escapes from pores of the filter cloth, an external force is applied to the filter-pressed materials, and falling and separation of the solid materials and the filter cloth after filter pressing are better facilitated. Fluid with pressure escapes from pores of the filter cloth, so that small particles remained in the pores can be separated. After the discharging state is finished, the filter pressing plates (04) are overlapped, so that the effect of cleaning the pores of the filter cloth is achieved. According to the scheme provided by the invention,the labor consumption of the plate filter press in an unloading state is reduced, the filter cloth can be kept in a relatively good working state, and the frequency of disassembly, cleaning and replacement is reduced.

Description

technical field [0001] The present application relates to the technical field of filter presses, in particular to a plate filter press. Background technique [0002] Plate filter press is used in the field of solid-liquid separation, and has a wide range of applications. In actual use, when the filter press process is over, the filter press plate (04) is released to start the unloading process. There are cases where the solid matter adheres to the filter cloth after the press filter, which requires manual cleaning and consumes more human resources. The fine solid particles in the material to be filtered are easy to invade the pores of the filter cloth, reducing the permeability of the filter cloth, reducing the working efficiency of the plate filter press, shortening the service life of the filter cloth, increasing the frequency of disassembly and cleaning, and shortening the the service life of the filter cloth. Contents of the invention [0003] The present applicati...
