[0039] Embodiment 2

[0040] The present embodiment provides a plate and frame filter press, comprising a thrust plate 1, a filter plate 2, a beam 17, a pressure plate 15, a hydraulic cylinder 16 and a cleaning device as in the first embodiment, wherein the filter cloth cleaning device 3 in the first embodiment is integrated into the plate and frame filter press, so that the plate and frame filter press can conveniently clean the filter cloth while performing filtering work, thereby improving the overall performance and working efficiency of the equipment and reducing the problem of decreased filtering efficiency due to filter cloth contamination.

[0041] Embodiment 3

[0042] The present invention also provides a method for using the filter cloth cleaning device 3 as in the first embodiment, comprising the following steps:

[0043] 1. Preparation

[0044] Move the sliding seat upward to a height higher than the filter cloth. This can prevent the roller brush and the water spraying part from colliding with the filter cloth or other parts during the movement of the walking trolley 12, ensuring the safe operation of the equipment. At the same time, it is also prepared for subsequent positioning and cleaning operations.

[0045] 2. Positioning Phase

[0046] The walking trolley 12 moves on the beam 17 of the plate-frame filter press to the position of the filter cloth that needs to be cleaned. The movement of the walking trolley 12 can cover the entire length range of the plate-frame filter press, so that the cleaning device can accurately reach the position of the filter cloth that needs to be cleaned. Through the precise movement of the walking trolley 12, the filter cloth at different positions can be cleaned in a targeted manner, improving the cleaning efficiency and coverage.

[0047] 3. Cleaning stage

[0048] The sliding seat moves downward along the guide rail 6, and drives the first roller brush, the first water spraying member, the second roller brush 20 and the second water spraying member to move downward. In this process, pressurized water enters the first water spraying member and the second water spraying member through the water source 7 pipe and sprays out, and the pressurized water cooperates with the rotation of the first roller brush and the second roller brush 20 to flush and clean the filter cloth.

[0049] The vertical movement of the sliding seat ensures that the roller brush and the water spraying member can accurately reach the cleaning position of the filter cloth, and can be accurately adjusted according to the thickness of the filter cloth and the cleaning requirements.

[0050] The first water spraying member and the second water spraying member spray water to both sides of the filter cloth respectively, and combined with the rotation of the first roller brush and the second roller brush 20, a strong flushing force is formed, which can effectively remove dirt and impurities on the filter cloth.

[0051] The rotation of the roller brush can increase the contact area and friction with the filter cloth, improving the cleaning effect. At the same time, the jet of pressurized water can wash away the dirt and impurities washed off, keeping the filter cloth clean.

[0052] Through the above three steps, the filter cloth of the plate and frame filter press can be cleaned efficiently and comprehensively, the filtering effect and service life of the filter cloth can be improved, and the maintenance cost and downtime of the equipment can be reduced.

[0053] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
