[0037] Embodiment two

[0038] The embodiment provides a plate-and-frame filter press, which comprises a thrust plate 1, a filter plate 2, a girder 17, a pressing plate 15, a hydraulic cylinder 16 and a cleaning device as in the embodiment one, the filter cloth cleaning device 3 in the embodiment one 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 the filtering work, the overall performance and working efficiency of the equipment are improved, and the problem of filtering efficiency reduction caused by filter cloth pollution is reduced.

[0039] Embodiment three

[0040] The utility model further provides a kind of use method of the filter cloth cleaning device 3 as in the embodiment one, comprising the following steps:

[0041] I, preparation stage

[0042] The sliding seat is moved upwards to the height higher than filter cloth. This can avoid collision between rolling brush and water spraying part and filter cloth or other components during the movement of walking trolley 12, and ensure the safe operation of the equipment. At the same time, it also prepares for subsequent positioning and cleaning operation.

[0043] II, positioning stage

[0044] Walking trolley 12 moves to the position of filter cloth to be cleaned on the girder 17 of plate-and-frame filter press. The movement of walking trolley 12 can cover the length range of plate-and-frame filter press, so that the cleaning device can accurately reach the position of filter cloth to be cleaned. Through the accurate movement of walking trolley 12, the filter cloth at different positions can be cleaned targetedly, improving the cleaning efficiency and coverage range.

[0045] III, cleaning stage

[0046] The sliding seat moves downward along the guide rail 6, and drives the first rolling brush, the first water spraying part, the second rolling brush 20 and the second water spraying part to move downward. In this process, the pressure water enters the first water spraying part and the second water spraying part through the water source 7 pipe and sprays out, and the pressure water cooperates with the self-rotation of the first rolling brush and the second rolling brush 20 to wash the filter cloth.

[0047] The vertical movement of the sliding seat ensures that the rolling brush and the water spraying part can accurately reach the cleaning position of the filter cloth, and can be accurately adjusted in position according to the thickness of the filter cloth and the cleaning requirement.

[0048] The first water spraying part and the second water spraying part spray water to the two sides of the filter cloth respectively, which, combined with the self-rotation of the first rolling brush and the second rolling brush 20, forms a strong washing force, which can effectively remove dirt and impurities on the filter cloth.

[0049] The self-rotation of the rolling brush can increase the contact area and friction force with the filter cloth, and improve the cleaning effect. At the same time, the injection of pressure water can flush away the dirt and impurities cleaned, and keep the filter cloth clean.

[0050] Through the operation of the above three steps, the filter cloth of the plate-and-frame filter press can be efficiently and comprehensively cleaned, the filtering effect and service life of the filter cloth are improved, and the maintenance cost and downtime of the equipment are reduced.

[0051] The principle and implementation mode of the utility model are described by applying specific examples in the utility model, and the above embodiment is only used for helping to understand the method and core idea of the utility model; meanwhile, for the general technical personnel in the field, the specific implementation mode and application range will be changed according to the idea of the utility model. In conclusion, the content of the specification should not be understood as the limitation of the utility model.
