[0002] Industrial wastewater treatment refers to the proper treatment of water used in industrial production processes for reuse in production or proper discharge from the factory. This includes the management of production water and measures taken to facilitate wastewater treatment.

[0003] Existing sedimentation tanks typically place the suction head of the sludge suction pipe at the bottom of the tank for extended periods. However, the accumulation of sludge can easily clog the suction head, reducing work efficiency. Furthermore, over time, sludge can adhere to the bottom and sides of the sedimentation tank, also affecting sedimentation efficiency. Utility Model Content

[0006] Furthermore, the lower end of the sedimentation tank shell is fixed to the ground by four sets of support legs.

[0007] Furthermore, a motor is fixedly installed on the inner side of the support leg, a first gear is fixedly connected to the power output shaft of the motor, a second gear is installed on the right side of the first gear, and a rotating shaft is fixedly installed on the upper end of the second gear.

[0008] Furthermore, an installation ring is fixedly installed inside the sedimentation tank shell, and an annular groove is provided on the lower side of the installation ring. A sliding part is slidably installed in the annular groove, and the sliding part is located at the upper end of the scraper.

[0009] Furthermore, a sludge discharge pipe is provided at the upper end of the rotating disk, and a sludge outlet pipe is provided on the right side of the sludge discharge pipe. The sludge outlet pipe is fixedly installed on the side wall of the sedimentation tank shell.

[0010] Furthermore, a central pipe is provided in the middle of the sedimentation tank shell, and an inlet pipe is fixedly installed on the left side wall of the central pipe, with the outlet of the inlet pipe located inside the central pipe.

[0012] Furthermore, a baffle is fixedly installed at the upper end of the sedimentation tank shell, and an overflow channel is formed between the baffle and the inner wall of the sedimentation tank shell. A drain pipe is fixedly connected to the upper side wall of the sedimentation tank shell.

[0013] The beneficial effects of this utility model are: by starting the motor to drive the rotating disk to rotate, the column rotates accordingly, which breaks up the sludge and prevents the sludge at the bottom of the sludge discharge pipe from becoming blocked. At the same time as the column rotates, the scraper also rotates synchronously, so that the rubber scraper on the scraper makes close contact with the inner wall of the sedimentation tank shell, scraping off the sludge adhering to the inner wall of the sedimentation tank shell and preventing it from affecting the sedimentation efficiency.

[0018] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.

[0019] like Figure 1As shown, this utility model includes a sedimentation tank shell 1, a central pipe 11 is provided in the middle of the sedimentation tank shell 1, an inlet pipe 12 is fixedly installed on the left side wall of the central pipe 11, the outlet of the inlet pipe 12 is located inside the central pipe 11, a reflector plate 10 is connected to the lower opening of the central pipe 11, a baffle 15 is fixedly installed at the upper end of the sedimentation tank shell 1, and an overflow channel 14 is formed between the baffle 15 and the inner wall of the sedimentation tank shell 1, and a drain pipe 13 is fixedly connected to the upper side wall of the sedimentation tank shell 1. Wastewater enters the central pipe 11 from the inlet pipe 12, and then flows into the sedimentation tank shell 1 for sedimentation through the reflector plate 10. The treated water at the top overflows into the overflow channel 14 and the drain pipe 13 and is discharged outside the device.

[0020] like Figure 1 As shown, the lower end of the sedimentation tank shell 1 is fixedly installed on the ground by four sets of support legs 2. A motor 3 is fixedly installed on the inner side of the support legs 2 by bolts. A first gear 4 is fixedly connected to the power output shaft of the motor 3. A second gear 5 is meshed on the right side of the first gear 4. A rotating shaft 6 is fixedly installed on the upper end of the second gear 5. The rotating shaft 6 is movably installed on the bottom of the sedimentation tank shell 1 through a sealed bearing 8. A rotating disk 7 is fixedly installed on the upper end of the rotating shaft 6. Several sets of columns 21 are fixedly installed on the upper end of the rotating disk 7. A sludge discharge pipe 9 is provided on the upper end of the rotating disk 7. A sludge outlet pipe 16 is provided on the right side of the sludge discharge pipe 9. The sludge outlet pipe 16 is fixedly installed on the side wall of the sedimentation tank shell 1. An external sludge pump is used to pump sludge from the outlet pipe 16. The rotating disk 7 is driven to rotate by starting the motor 3, which causes the columns 21 to rotate accordingly, breaking up the sludge and preventing the sludge at the bottom of the sludge discharge pipe 9 from clogging.
