[0033] Furthermore: The staff can control the connection relationship between the clamping rods 1305 on the front and rear sides and the clamping seat 1201 and the water return device 3 by pulling the pulling rod 1402, so that the staff can quickly complete the disassembly and assembly of the filter plate 1103. At the same time, multiple filter plates 1103 can be independently disassembled and assembled. When the staff replaces a single filter plate 1103, it will not affect the overall use of the device, which is convenient for the staff to use.

[0034] Embodiment 2

[0035] Refer to Figures 1 to 6 and, on the basis of Embodiment 1, it is further obtained that the positioning mechanism 2 includes a positioning component 21, a reset component 22 and a stabilizing component 23. The positioning component 21 is arranged on the top of the lifting component 12. The reset component 22 is arranged inside the positioning component 21. The stabilizing component 23 is arranged inside the reset component 22.

[0036] The positioning component 21 includes a convex plate 2101, the convex plate 2101 is fixedly connected to the top of the card seat 1201, a limiting plate 2102 is arranged on the outer side of the convex plate 2101, a pull ring 2103 is fixedly connected to the outer side of the limiting plate 2102, a positioning rod 2104 is fixedly connected to the inner side of the limiting plate 2102, the positioning rod 2104 is clamped inside the left and right sides of the pull rod 1402, the reset component 22 includes a telescopic tube 2201, the telescopic tube 2201 is fixedly connected to the inner side of the limiting plate 2102, the telescopic tube 2201 is slidably connected inside the convex plate 2101, a fixing piece 2202 is fixedly connected to the inner side of the outer ring of the telescopic tube 2201, a reset spring 2203 is fixedly connected to the outer side of the fixing piece 2202, the reset spring 2203 is fixedly connected to the inner side of the convex plate 2101, the stabilizing component 23 includes a telescopic rod 2301, the telescopic rod 2301 is slidably connected inside the telescopic tube 2201, a fixing frame 2302 is fixedly connected to the middle of the outer ring of the telescopic rod 2301, and the fixing frame 2302 is fixedly connected to the top of the card seat 1201.

[0037] Furthermore: After the pull rod 1402 is pulled inward, the positioning rod 2104 can be clamped inside the left and right sides of the pull rod 1402 to complete the positioning of the pull rod 1402, so that when the staff disassembles the filter plate 1103, there is no need to always apply force to the front and rear pull rods 1402, which is convenient for the staff to use.

[0038] During the actual operation process, when this device is in use and the filter plate 1103 needs to be disassembled, the staff first pulls the pull rings 2103 on the left and right sides to move outward. The outward movement of the pull rings 2103 drives the positioning rod 2104 to move outward through the limiting plate 2102. Then the staff pulls the pull rod 1402 on the front or rear side of the card seat 1201 to move inward. The inward movement of the pull rod 1402 drives the clamping rod 1305 to retract into the card seat 1201 through the moving slide rod 1401 and the sliding cylinder 1301 until the pull rod 1402 aligns with the positioning rod 2104. Then the staff releases the pulling of the pull ring 2103. At this time, the fixing pieces 2202 on the left and right sides will drive the limiting plate 2102 to move inward through the telescopic tube 2201 under the action of the reset spring 2203. The inward movement of the limiting plate 2102 drives the positioning rod 2104 to move inward, and the inward movement of the positioning rod 2104 is clamped inside the left and right sides of the pull rod 1402 to complete the positioning of the pull rod 1402. After that, repeat the above operation to adjust and position the clamping rod 1305 on the other side of the card seat 1201. Then the staff only needs to pull the sliding frame 1302 upward to drive the card frame 1102 and the filter plate 1103 upward to complete the disassembly of the filter plate 1103.

[0039] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent in such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.
