For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] like Figures 1 to 6 As shown, this embodiment provides a vertical plate filter module, including a filter tank 100, and a water inlet pipe 1 for the liquid to be treated to enter the filter tank 100, and the liquid to be treated enters the filter tank 100 through the water inlet pipe 1; the filter tank 100 is provided with a filter plate frame 15, and a support frame 3 is installed on the filter plate frame 15 near the position of the water inlet pipe 1 through a connecting flange 2, and at least one group of independently arranged filter systems 8 are arranged on the support frame 3;

[0031] The filtering system 8 includes at least one group of independently arranged filtering skeletons 7, and the filtering skeleton 7 is made of C-shaped steel with a length of 1m, a width of 100mm, a height of 70mm, and a thickness of 3mm; at least one group of connecting plates 4 is welded on the filtering skeleton 7 near the position of the water inlet pipe 1, and a positioning hole is opened on the connecting plate 4 at one end away from the filtering skeleton 7, and a fixed connecting member 13 for connecting the filtering skeleton 7 and the supporting frame 3 is arranged in the positioning hole. The filtering skeleton 7 and the supporting frame 3 are detachably connected. The fixed connecting member 13 is preferably a fastening screw connection assembly, and when in use, the connection between the filtering skeleton 7 and the supporting frame 3 is realized by the fixed connecting member 13.

[0032] In actual application, since the filter cloth in the existing vertical plate filter tank is of integral design, it is troublesome to install and replace the filter cloth in the subsequent maintenance, and special lifting tools are required to lift it out, which has the disadvantages of inconvenient operation and high maintenance cost.

[0033] In this embodiment, the filter system 8 includes at least one set of independently arranged filter skeletons 7 to replace the traditional integrated design. When one set of filter cloths arranged on the filter skeleton is damaged, only the damaged filter cloth needs to be replaced.

[0034] In actual installation, the filter cloth is put on the filter cloth frame, and then the four corners of the filter cloth are tied together by ropes. In actual use, the operation is relatively cumbersome. When the filter cloth is damaged, it is necessary to take out the integrated filter cloth frame and untie all the ropes of the filter cloth before the filter cloth can be replaced. In order to solve the above technical problems, please refer to Figures 1 to 6 As shown, the filtering system 8 further comprises a filter cloth frame 9, and filter cloth is installed on the outside of the filter cloth frame 9, and the filter cloth frame equipped with the filter cloth is installed on the filtering skeleton 7 through a fixed connection assembly.

[0035] Furthermore, the fixed connection assembly includes two sets of detachable first filter base 11 and second filter base 6; and the first filter base 11 is fixedly mounted on the filter cloth frame 9 by means of a fixed connection such as fastening screws and welding.

[0036] Furthermore, threaded holes 19 are provided on the filter cloth frame 9 and the first filter base 11 , and fastening screws are provided in the threaded holes 19 .

[0037] During installation, the filter cloth only needs to be placed on the filter cloth frame, and then the fastening screws are sequentially passed through the threaded holes on the filter cloth and the threaded holes on the first filter base, and then extended into the threaded holes 19 on the filter cloth frame 9 and tightened to achieve the installation of the filter cloth.

[0038] Furthermore, the first filter base 11 is 70 mm long and 100 mm wide; the first filter base 11 is provided with an inclined end portion, the first filter base 11 continuously extends along its longitudinal direction and intersects with the inclined end portion to form an angle α, and α is 15°.

[0039] Furthermore, the second filter base 6 is fixedly mounted on the filter frame 7 by means of a fixing connection such as fastening screws or welding. The first filter base 11 is provided with a slot for the second filter base 6 to extend into, and when the filter cloth frame equipped with the filter cloth is mounted on the filter frame, the inclined end of the cross section of the second filter base 6 conflicts with the inclined end of the cross section of the first filter base 11.

[0040] Furthermore, a counterbore 21 is provided on both the fixed connection assembly 1 and the filter frame 7, and a limit connection member 21 is provided in the counterbore 21, the limit connection member 21 comprises a screw end 201 and a limit end, and the limit end is provided at one end of the screw end 201, and the limit end is integrated with the screw end 201. The limit end provided on the screw end 201 passes through the counterbore on the fixed connection assembly and extends into the counterbore of the filter frame 7.

[0041] Furthermore, the screw end 201 passes through the threaded hole of the filter cloth, and the screw end extending out of the positioning hole is threadedly connected to the fastening connector 202 .

[0042] Furthermore, screw holes for accommodating the limiting ends are provided in the first filter base 11 and the second filter base 6, so that the limiting ends of the limiting connector are just located in the screw holes; the limiting nut of the limiting connector arranged in the countersunk hole 21 and the force generated between the two groups of filter bases (the first filter base and the second filter base) can effectively prevent the limiting connector from loosening, thereby improving the stability of the filter cloth installation.

[0043] Furthermore, the countersunk hole 21 is 18 mm wide and 4 mm deep.

[0044] Furthermore, in order to avoid loosening during installation, a limiting screw can be installed longitudinally (in the direction extending from the first filter base toward the second filter base) at the limiting end position of the fixed connection assembly to prevent the limiting connection piece from loosening.

[0045] See also Figure 1 As shown, the filter plate frame 15 at a position far away from the water inlet pipe 1 is connected to the water outlet pipe 5 through the filter plate water outlet connecting flange 14 .

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not restrictive. Although the utility model is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solution of the utility model does not deviate from the spirit and scope of the technical solution of the utility model, and should be included in the scope of the claims of the utility model.
