Example Embodiment

[0009]Specific implementation

[0010]The fluid (01) mentioned in the embodiments of this application refers to a substance that can be filled into the fluid storage cavity (06) and can deform the fluid storage cavity (06), including but not limited to air, water And oily substances, usually compressed air.

[0011]After the filter press state of the plate filter press described in the examples of this application ends, the unloading process starts, the filter press plate (04) is loosened, and the sampling cart pulls the filter press plate (04) one by one, adjacent When the filter press plate (04) is pulled a certain distance, the device for controlling the fluid (01) to enter the fluid storage cavity (06) is turned on.

[0012]The device for controlling the fluid (01) to enter the fluid storage chamber (06) includes but is not limited to the following two types: 1. A mechanical device with a part that controls opening and closing. When two adjacent filter plates ( 04) When fitting, it direc...

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...
