[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3 In the embodiment of the present invention, a filtering structure of a flow meter includes a tube body 1 and a flow meter body 2 arranged on the top of the tube body 1. Both ends of the tube body 1 are fixedly connected to a first flange 3. A filter tube 4 is provided on one side of the tube body 1. Both ends of the filter tube 4 are fixedly connected to a second flange 5, and one of the second flanges 5 is connected to the first flange 3 by a component that is easy to install and disassemble. The disassembly component includes a connecting plate 11 welded to one side of the second flange 5. A rotating groove 12 is opened on one side of the first flange 3 near the connecting plate 11. The end of the connecting plate 11 It extends into the interior of the rotating groove 12 and is rotatably connected to the rotating groove 12. Circular grooves 13 are symmetrically provided on the top and bottom of the connecting disk 11. A spring 14 is welded to the inner wall of the circular groove 13. The other end of the spring 14 is fixedly connected to a limiting rod 15. A through hole 16 connected to the circular groove 13 is provided on the top and bottom surfaces of the first flange 3. One end of the limiting rod 15 away from the spring 14 passes through the circular groove 13 and the through hole 16 and extends to the outside of the first flange 3. The limiting rod 15 is slidably connected to the circular groove 13 and the through hole 16. The circular groove 13 and the through hole 16 are set to the same aperture size.

[0019] When in use, the operator presses the limit rod 15 to move it into the circular groove 13, and the spring 14 is compressed and deformed. Then, the operator picks up the filter tube 4 and slides the connecting disk 11 into the rotating groove 12. When the connecting disk 11 is inserted into the rotating groove 12, the inner wall of the rotating groove 12 continues to exert an extrusion force on the limit rod 15, so that it is always in the corresponding circular groove 13. Then, the filter tube 4 is rotated to make the connecting disk 11 rotate in the rotating groove 12. When the limit rod 15 reaches the through hole 16 under the rotation of the connecting disk 11, the spring 14 is elastically reset and deformed, thereby driving the limit rod 1 5 slides out of the circular groove 13 and passes through the through hole 16 to reach the outside of the first flange 3, thereby fixing the first flange 3 and the second flange 5 together. Then, the mounting holes on both sides of the first flange 3 and the second flange 5 are fixed by external nuts and screws, thereby strengthening the installation and fixation between the pipe body 1 and the filter tube 4. Conversely, the limiting rod 15 is pressed from the outside of the first flange 3 through the through hole 16 into the circular groove 13 where it is located. Then, holding the filter tube 4, the connecting plate 11 can be pulled out of the rotating groove 12. The operation is simple and convenient, and it is convenient for quickly disassembling the pipe body 1 and the filter tube 4.

[0020] The interior of the filter tube 4 is provided with a filter assembly for filtering impurities, and the filter assembly includes a filter cartridge 21 and fan blades 22. A fixed disk 6 is welded to the inner wall of the filter tube 4 close to the tube body 1. One end of the filter cartridge 21 is rotatably connected to the interior of the fixed disk 6, and the fan blades 22 are fixedly installed on the side wall of the other end of the filter cartridge 21. The filter cartridge 21 is configured to be a hollow cone, which can improve the filtering efficiency. When in use, the fan blades 22 rotate under the impact of the water flow, thereby driving the filter cartridge 21 to rotate and filter. The fixed disk 6 is set so that the filter cartridge 21 can only rotate in a circumferential direction without moving in position.

[0021] A cleaning brush 7 is provided on the side wall of the filter cartridge 21, and the brush surface of the cleaning brush 7 is in contact with the surface of the filter cartridge 21. A fixing rod 8 is symmetrically welded to the side of the cleaning brush 7 away from the filter cartridge 21, and the other end of the fixing rod 8 is welded to the inner wall of the filter tube 4. When in use, when the filter cartridge 21 is rotating for filtering, since the cleaning brush 7 is fixed, it can continuously clean and brush off impurities attached to the surface of the filter cartridge 21, thereby further improving the filtering effect of the filter cartridge 21, eliminating the need for manual cleaning, and improving practicality.

[0022] Working principle: When in use, the operator first presses the limit rod 15 to place it in the circular groove 13, and the spring 14 is compressed at the same time. Then, the operator picks up the filter tube 4 and slides the connecting disk 11 into the rotating groove 12. At this time, the inner wall of the rotating groove 12 continues to exert an extrusion force on the limit rod 15, so that it is always in the circular groove 13. Then, the filter tube 4 is rotated to make the connecting disk 11 rotate accordingly. When the limit rod 15 reaches the through hole 16 under the rotation of the connecting disk 11, the spring 14 is elastically reset, thereby driving the limit rod 15 to penetrate the circular groove 13 and the through hole 16 and move to the outside of the first flange 3, so that the tube body 1 and the filter tube 4 can pass through the first flange 3 is fixed together with the second flange 5, and then the external nut screw is threadedly rotated into the mounting holes on both sides of the first flange 3 and the second flange 5, thereby strengthening the installation and fixation between the pipe body 1 and the filter tube 4, and then the pipe body 1 and the filter tube 4 are installed on the conveying pipeline through the first flange 3 and the second flange 5 on the other side. When water flows into the filter tube 4, the fan blades 22 drive the filter cartridge 21 to rotate and filter under the impact of the water flow. At this time, since the cleaning brush 7 is fixed, the cleaning brush 7 can clean and brush off the impurities attached to the surface of the filter cartridge 21 as it rotates, thereby improving the filtering effect of the filter cartridge 21.

[0023] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
