[0041] Second Embodiment

[0042] Please refer to Figures 4 - 5 , Figure 4 which is a schematic structural diagram of the second embodiment of the high-sealing metal wound gasket with a filter net provided by the present utility model; Figure 5 which is a schematic structural diagram of the bolt provided by the present utility model. Based on the high-sealing metal wound gasket with a filter net provided in the first embodiment of the present application, the second embodiment of the present application proposes another high-sealing metal wound gasket with a filter net. The second embodiment is only a preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0043] Specifically, the difference of the high-sealing metal wound gasket with a filter net provided in the second embodiment of the present application is that a rotating bolt 14 is fixedly connected to the top of the filter disc 10, and a flow fan 16 is rotatably connected to the top end of the rotating bolt 14;

[0044] The flow fan 16 can be driven to rotate by the flow of the fluid, and the rotating bolt 14 and the flow fan 16 are connected by a bearing.

[0045] A mounting bracket 15 is fixedly connected to the bottom of the flow fan near the middle, and the mounting bracket 15 is L-shaped;

[0046] The mounting bracket 15 is provided with an opening for the mounting bolt 18 to pass through.

[0047] A cleaning brush 17 is arranged at the bottom of the mounting bracket 15, and a mounting bolt 18 is installed at the top of the mounting bracket 15;

[0048] The mounting bolt 18 mounts the cleaning brush 17 at the bottom of the mounting bracket 15, and the cleaning brush 17 contacts the top end of the filter disc 10.

[0049] Compared with the related art, the high-sealing metal wound gasket with a filter net provided by the present utility model has the following beneficial effects:

[0050] To prevent the filter disc 10 from being blocked during use, a circulation fan 16 is installed at the top of the filter disc 10 through a rotating bolt 14. An L-shaped mounting bracket 15 is installed at the bottom of the circulation fan 16, with the mounting bracket 15 close to the inlet end of the filter disc 10. A cleaning brush 17 is installed between the mounting bracket 15 and the filter disc 10 through a plurality of mounting bolts 18. During actual use, the flow rate of the fluid drives the circulation fan 16 to rotate, which in turn drives the mounting bracket 15 to rotate. During this process, the cleaning brush 17 in contact with the filter disc 10 rotates synchronously. As the cleaning brush 17 rotates, it drives the debris on the outer surface of the filter disc 10 towards the outer surface, preventing the debris from entering the liquid flow of the filter disc 10. With this structure, when the filter disc 10 filters the liquid, the cleaning brush 17 can clean its surface to reduce the probability of blockage, which is beneficial to liquid transportation.
