Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 6 The wastewater treatment filtration device shown includes:

[0027] A filter frame 1 is provided with a collection frame 2 at the bottom of the filter frame 1. A sealing gasket 16 is fixedly provided at the bottom of the filter frame 1. The bottom of the sealing gasket 16 contacts the top of the collection frame 2. A fixed cylinder 3 is fixedly provided at the bottom of the collection frame 2. A filter screen cylinder 4 is provided at the top of the fixed cylinder 3. An annular slip ring 14 is fixedly provided at the bottom of the filter screen cylinder 4. An annular groove 15 is opened at the top of the fixed cylinder 3. The annular slip ring 14 is located inside the annular groove 15. A rotating tube 5 is fixedly provided at the top of the filter screen cylinder 4 and communicates with its interior. The top of the rotating tube 5 passes through the top of the filter frame 1 and is rotatably connected to the filter frame 1 through a bearing. A power component is connected to the rotating tube 5.

[0028] Multiple telescopic rods 6 are provided. One end of each telescopic rod 6 is fixedly connected to the inner rear wall of the filter frame 1. A cleaning plate 7 is fixedly provided at the other end of each telescopic rod 6. A cleaning brush 8 is fixedly provided at the front end of the cleaning plate 7. The cleaning brush 8 is in contact with the outer end of the filter screen cylinder 4. A spring 9 is sleeved on the outer end of each telescopic rod 6. The two ends of the spring 9 are fixedly connected to the inner rear wall of the filter frame 1 and the rear end of the cleaning plate 7, respectively.

[0029] The power assembly includes a motor 10 fixedly mounted on the top of the filter frame 1. The output shaft of the motor 10 is fixedly mounted with a rotating rod 11. The bottom end of the rotating rod 11 is rotatably connected to the top of the filter frame 1. The outer end of the rotating rod 11 is fixedly mounted with a drive gear 12. The outer end of the rotating tube 5 is fixedly mounted with a driven gear 13. The drive gear 12 and the driven gear 13 mesh with each other.

[0030] A liquid inlet pipe 17 is fixedly provided on one side of the filter frame 1 and communicates with the inside of the filter frame 1. A liquid outlet pipe 18 is provided at the top of the rotating tube 5. One end of the liquid outlet pipe 18 passes through the top of the rotating tube 5 and is rotatably connected to the top of the rotating tube 5 through a sealed bearing. One end of the liquid outlet pipe 18 is connected to the inside of the rotating tube 5. A connecting frame 19 is fixedly provided on the bottom outside of the filter frame 1 and the top outside of the collection frame 2.
