DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model.

[0022] Please refer to Figures 1 to 6, provide a kind of filter cloth automatic transmission device of filter machine, provide a kind of embodiment below: including multiple filter plates 31 and multiple plate frames 32, the multiple filter plates 31 and the multiple plate frames 32 are arranged in a row in the way of alternation, the filter plate 31 is equipped with plate body 311, two opposite arrangement extrusion membrane 312 and plate guide roller 315, plate guide roller 315 is located at the directly below of plate body 311, two extrusion membranes 312 are located in the middle part of plate body 311 and form extrusion cavity, plate body 311 is equipped with extrusion water gap 313 and water outlet passage 314, extrusion water gap 313 is communicated with extrusion cavity, plate frame 32 is equipped with frame body 321 and frame guide roller 325, frame guide roller 325 is located at the directly above of frame body 321, frame body 321 is equipped with filter cavity 322 corresponding with extrusion cavity and feed water gap 323, feed water gap 323 is communicated with filter cavity 322.In use, filter cloth is hung in order in the surface of plate guide roller 315 and frame guide roller 325, filter cloth moves forward by plate guide roller 315 and frame guide roller 325, when filtering, filter cloth stops moving, filter plate 31 and frame plate will filter cloth be clamped in the middle, material water flows into filter cavity from feed water gap 323 in the upper end of plate frame 32 and penetrates filter cloth, filter cloth is extruded by two sides of extrusion membrane 312, and clean water flows out from the lower end of water outlet passage 314 of filter plate 31, the advantage of such is that it can guarantee that filter cake is only deposited on filter cloth, saves the time of subsequent replacement of filter cloth, and the filter cavity space is larger, and the filtering efficiency is higher.

[0023] Specifically, the extrusion membrane 312 is a rubber mold. The rubber mold has good deformability and can closely fit the filter cloth. The extrusion mold 312 is square-shaped and consistent in size with the filter cavity 322. When the extrusion mold 312 is pushed to the limit position, the two extrusion molds 312 clamp the filter cloth, and the extrusion membranes 312 on both sides extrude into the filter cavity 322, thereby extruding the water absorbed by the filter cloth.

[0024] Specifically, the extrusion water gap 313 is four, and the four extrusion water gaps 313 are respectively located at the four corner portions of the plate body 311. In use, extrusion water enters the extrusion cavity from the four extrusion water gaps 313, the extrusion cavity expands to both sides, and the extrusion membrane 312 is pushed outwards. When extruding, extrusion water is injected into the extrusion cavity. When the extrusion is completed, the extrusion water is discharged from the extrusion water gap 313. The extrusion cavity is a closed space. Because the pressure in the extrusion cavity becomes smaller, the external air pressure is greater than the internal air pressure, and the extrusion membrane 312 absorbs into the extrusion cavity.

[0025] Specifically, the plate frame 32 is provided with a scratch plate 324 between the frame body 321 and the frame guide roller 325. While the filter cloth moves through the plate guide roller 315 and the frame guide roller 325, one side of the filter cloth passes through the scratch plate 324, which can remove part of the filter cake on the surface of the filter cloth, thereby cleaning the filter cloth.

[0026] Specifically, the input end of the water outlet channel 314 is provided with a plurality of uniformly arranged water holes. Since the material water is injected from the material water inlet 323 at the upper end of the plate frame 32, flows into the filter cavity after passing through the filter cloth, the filter cloth changes the original flow path of the material water and randomly falls at the lower end of the filter plate 31. Therefore, a plurality of uniformly arranged water holes are arranged at the lower end of the filter plate 31, which can accelerate the discharge speed of the material water. The water holes can also prevent impurities from falling into the water outlet channel 314 through the filter cloth under special circumstances, thereby affecting the overall filtering effect.

[0027] Specifically, each filter plate 31 is connected in sequence through a connecting chain, and each plate frame 32 is connected in sequence through a connecting chain. By connecting each filter plate 31 and each plate frame 32 through a connecting chain, the maximum distance between each filter plate 31 and each plate frame 32 can be limited, and the synchronous movement of each filter plate 31 and each plate frame 32 can be ensured.

[0028] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can make equivalent replacements or changes to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
