[0020] like Figure 1-4 As shown, the utility model provides a sewage treatment plant sewage pipe filtering device, including a filtering device main body 1, the filtering device main body 1 includes a connecting pipe 2, a bottom connecting pipe 3 connected to the bottom of the connecting pipe 2 and a filter pipe 6 connected to the end of the connecting pipe 2, a filter screen cartridge 4 is installed in the bottom connecting pipe 3, a filtering structure is provided in the filter pipe 6, the connecting pipe 2, the bottom connecting pipe 3 and the movable ends of the filter pipe 6 are all connected with a threaded gland 5, a threaded gland 5 is connected between the connecting pipe 2 and the filter pipe 6, and the movable end of the filter pipe 6 is provided with an inner wall brushing component driven by water flow.

[0021] The movable ends of the connecting pipe 2, the bottom connecting pipe 3 and the filter pipe 6 are all installed with threaded glands 5, and the external pipes are connected through the threaded glands 5. The movable ends of the connecting pipe 2 and the bottom connecting pipe 3 are connected to the water supply pipe, and the movable end of the filter pipe 6 is connected to the drainage pipe. The sewage entering the connecting pipe 2 is preliminarily filtered by the filtering structure. After the filtration is completed, the sewage passes through the inner wall brushing component and drives the inner wall brushing component to rotate to brush the inner wall of the pipe connected to the filter pipe 6; the sewage entering the bottom connecting pipe 3 first passes through the filter mesh cylinder 4, and the sewage is preliminarily filtered by the filter mesh cylinder 4, and then filtered again by the filtering structure. The double filtration form is used to enhance the filtration effect to achieve the treatment of sewage with more impurities.

[0022] like Figure 2 and Figure 4 As shown. The inner wall scrubbing assembly includes a water flow wheel 14 that is rotatably arranged within the filter tube 6, a scrubbing rack that is coaxially mounted within the filter tube 6, and a transmission gear set 15 between the water flow wheel 14 and the scrubbing rack. A guide plate is provided upstream of the inner wall scrubbing assembly, and the transmission gear set 15 includes two intermeshing bevel gears. The guide plate is mounted on the inner top of the filter tube 6. The inclined arrangement of the guide plate allows sewage to flow from the bottom of the filter tube 6 and flush the bottom of the water flow wheel 14, causing the water flow wheel 14 to rotate in a certain direction. During the rotation of the water flow wheel 14, the scrubbing rack is driven by the transmission gear set 15 to rotate, and the scrubbing rack cleans the inner wall of the pipe connected to the movable end of the filter tube 6.

[0023] like Figure 3 As shown, a fixed connecting rod 12 is fixedly installed within the filter tube 6. A connecting sleeve shaft 13 is rotatably connected to the movable end of the fixed connecting rod 12. The water flow power wheel 14 is coaxially fixedly connected to the connecting sleeve shaft 13. The fixed connecting rod 12 is fixedly connected within the filter tube 6. The water flow drives the water flow power wheel 14 to rotate. The rotation of the water flow power wheel 14 drives the connecting sleeve shaft 13, which in turn drives the active bevel gear in the transmission gear set 15. The active bevel gear drives the meshing driven bevel gear, which in turn drives the scrubbing frame.

[0024] like Figure 2 The scrubbing frame includes a coupling 16 coaxially connected to the filter tube 6, a cleaning rod 17 radially fixedly connected to the coupling 16, and a cleaning block 18 fixedly connected to the movable end of the cleaning rod 17. A transmission gear set 15 rotates the coupling 16, which in turn rotates the cleaning block 18 via the cleaning rod 17. The rotation of the cleaning block 18 cleans the inner wall of the pipe.

[0025] As a preferred embodiment of the present invention, the cleaning block 18 is a rubber block. The cleaning block 18 can be compressed and can fully fit the inner wall of the pipeline.

The three-layer circular filter 8 is filled with an activated carbon filter layer 9 and a ceramsite filter layer 10 along the water flow direction. A conical filter cartridge 11 is fixedly installed downstream of the three-layer circular filter 8. The activated carbon filter layer 9 is made of activated carbon, the ceramsite filter layer 10 is made of ceramsite, and the conical filter cartridge 11 is made of stainless steel. Activated carbon has the advantages of strong adsorption and filtration; ceramsite has the advantage of good filtration; and stainless steel has the advantages of being resistant to rust and having high hardness.

[0027] like Figure 2 As shown, in order to enhance the sealing performance of the pipeline connection position, a sealing ring 7 is coaxially fixedly provided on the inner side of the threaded gland 5.
