DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3A sewage treatment device comprises a filter box 1, a sedimentation box 13 and a treatment cylinder 19. A water inlet 2 is arranged on the top of the filter box 1. A solid collecting box 3 is slidably inserted on one side of the filter box 1. A plurality of filter holes 9 are arranged on the bottom of the solid collecting box 3. A rotating shaft 6 is rotatably inserted between the inner walls on both sides of the filter box 1. A filter plate 5 is clamped on the outer wall of the rotating shaft 6. The filter plate 5 is used to filter large particles of solid impurities in the sewage. One end of the filter plate 5 is located above the solid collecting box 3. An inclined plate 8 is fixed between the inner wall of the top and one side of the inner wall of the filter box 1 by bolts. An electric push rod 7 is rotatably connected to one side of the inclined plate 8. One end of the electric push rod 7 is rotatably connected to the filter plate 5. The filter plate 5 rotates under the drive of the electric push rod 7, so as to prevent large particles of solid impurities from accumulating on the filter plate 5. A first connecting pipe 11 is inserted, and a filter screen 10 is clamped at one end of the first connecting pipe 11 close to the filter box 1. The filter screen 10 is used to filter small particles of solid impurities in the sewage. A collecting tank 15 is slidably inserted at the bottom of one side of the sedimentation box 13, and the sediment falls into the collecting tank 15 for collection. A second connecting pipe 18 is inserted between the sedimentation box 13 and the treatment cylinder 19. A motor 20 is fixed to the top outer wall of the treatment cylinder 19 by bolts. The output end of the motor 20 is keyed to a stirring shaft 21. A plurality of stirring blades 22 are fixed to the outer wall of the stirring shaft 21 by bolts. The stirring blades 22 are arranged in the treatment cylinder 19. The stirring shaft 21 rotates under the drive of the motor 20, thereby driving the stirring blades 22 to rotate, thereby stirring the disinfectant and the sewage, so as to disinfect the sewage. A water outlet pipe 23 is inserted at one side of the treatment cylinder 19.

[0023] The first connecting pipe 11 and the second connecting pipe 18 are both provided with a regulating valve 12, and a dosing port 14 is provided on the top of the sedimentation tank 13. Flocculant is put into the sedimentation tank 13 through the dosing port 14 to accelerate the sedimentation of sewage. A handle 16 is fixed to the outer wall of one side of the collecting tank 15 by bolts, so as to facilitate the operation of the collecting tank 15. A plurality of footings 17 are fixed to the bottom outer wall of the sedimentation tank 13 by bolts, and the sedimentation tank 13 is supported by the footings 17. A drug inlet 24 is provided on the top of the treatment cylinder 19 so that the disinfectant can be put into the treatment cylinder 19. A plurality of support columns 4 are fixed to the bottom outer wall of the filter box 1 by bolts, so as to support the filter box 1.

[0024] The working principle of this embodiment is as follows: when in use, first, the sewage is injected into the filter box 1 from the water inlet 2, and then the sewage falls on the filter plate 5, so that the large particles of solid impurities in the sewage are filtered by the filter plate 5, and then the large particles of solid impurities roll along the filter plate 5 into the solid collection box 3. At the same time, the filter plate 5 rotates under the drive of the electric push rod 7, so as to prevent the large particles of solid impurities from accumulating on the filter plate 5, and then the sewage falls on the bottom of the filter box 1, and then the regulating valve 12 of the first connecting pipe 11 is opened, and the sewage in the filter box 1 is input into the solid collection box 3 through the first connecting pipe 11. The sewage is precipitated in the sedimentation tank 13 and the precipitate falls into the collecting tank 15. Then, a flocculant is put into the sedimentation tank 13 from the dosing port 14 to accelerate the sedimentation of the sewage. Next, the regulating valve 12 of the second connecting pipe 18 is opened, and the sewage in the sedimentation tank 13 is input into the treatment cylinder 19 through the second connecting pipe 18. Then, a disinfectant is put into the treatment cylinder 19 from the drug inlet 24. Then, the stirring shaft 21 is rotated under the drive of the motor 20, thereby driving the stirring blade 22 to rotate, and then the disinfectant and the sewage are stirred to disinfect the sewage. Finally, the sewage is discharged from the outlet pipe 23.
