[0029] See also Figure 1-4 The utility model provides a technical solution: a municipal sewage sedimentation tank, comprising a municipal sewage sedimentation tank 1, a sludge cleaning component, the sludge cleaning component is arranged inside the municipal sewage sedimentation tank 1, the sludge cleaning component comprises a driving motor 2, the driving motor 2 is fixedly connected to the surface of the municipal sewage sedimentation tank 1, the output end of the driving motor 2 is fixedly connected with a threaded rod 5, the interior of the municipal sewage sedimentation tank 1 is fixedly connected with a fixed bracket 3, the two ends of the threaded rod 5 are respectively rotatably connected to the inner wall of the municipal sewage sedimentation tank 1 and the fixed bracket 3, the interior of the municipal sewage sedimentation tank 1 is fixedly connected with two fixed rods 4, the two fixed rods 4 are fixedly connected to the fixed bracket 3, the surface of the threaded rod 5 is threadedly sleeved with a movable plate 6, the movable plate 6 is slidably connected to the two fixed rods 4, the lower end of the movable plate 6 is rotatably connected with a sludge scraper 7, and the surface of the movable plate 6 is fixedly connected with a scraper limit plate 8.

[0030] The sludge cleaning component also includes a drive motor 29, which is fixedly connected to the surface of the municipal sewage sedimentation tank 1. The output end of the drive motor 29 is fixedly connected to a rotating shaft 10, and the rotating shaft 10 is rotatably connected to the municipal sewage sedimentation tank 1. Two connecting rods 11 are fixedly connected to the surface of the rotating shaft 10, and the opposite surfaces of the two connecting rods 11 are fixedly connected to sludge scrapers 2 12.

[0031] The fixed rod 4 and the threaded rod 5 are tiltedly arranged inside the municipal sewage sedimentation tank 1. The bottom surface of the municipal sewage sedimentation tank 1 is tilted, and the fixed rod 4 and the threaded rod 5 are consistent with the tilt angle of the bottom surface of the municipal sewage sedimentation tank 1. The sludge scraper 1 7 is in contact with the scraper limit plate 8. The sludge scraper 2 12 is in an arc shape. The lowest part of the municipal sewage sedimentation tank 1 is a circular arc surface. The sludge scraper 2 12 is in contact with the circular arc surface of the municipal sewage sedimentation tank 1.

[0032] One end of the municipal sewage sedimentation tank 1 away from the driving motor 2 is fixedly connected to a fixed bracket 2, a telescopic rod 15 is fixedly connected inside the fixed bracket 14, and a sludge baffle 16 is fixedly connected to the output end of the telescopic rod 15. A sludge channel 13 is provided on the inner wall of the municipal sewage sedimentation tank 1, and a slide groove 17 is provided on the surface of the municipal sewage sedimentation tank 1, and the sludge baffle 16 is slidably connected to the slide groove 17.

[0033] When using the sewage sedimentation tank, sewage is injected into the municipal sewage sedimentation tank 1. After a period of sedimentation, the sludge will sink to the bottom of the municipal sewage sedimentation tank 1. First, the sewage in the upper layer of the municipal sewage sedimentation tank 1 is pumped out by the sewage pump, and the driving motor 2 is started to drive the threaded rod 5 to rotate. The threaded rod 5 drives the movable plate 6 to slide on the surface of the fixed rod 4. The movable plate 6 drives the sludge scraper 7 and the scraper limit plate 8 to move, so that the sludge scraper 7 scrapes the bottom of the municipal sewage sedimentation tank 1 and scrapes the sludge to the arc bottom surface at the bottom of the municipal sewage sedimentation tank 1.

[0034] Since the scraper limit plate 8 limits the sludge scraper 7, the sludge scraper 7 can scrape the sludge when it is away from the drive motor 2. When the sludge scraper 7 is close to the drive motor 2, the sludge scraper 7 is resisted by the sludge, and the sludge scraper 7 is separated from the scraper limit plate 8. The sludge scraper 7 and the movable plate 6 rotate, which can prevent the sludge from accumulating on the inner wall of the municipal sewage sedimentation tank 1 close to the drive motor 2.

[0035] Then, the driving motor 29 is started to drive the rotating shaft 10 and the connecting rod 11 to rotate, and the connecting rod 11 drives the sludge scraper 2 12 to rotate. The sludge scraper 2 12 scrapes the sludge, and at the same time, the telescopic rod 15 is started to drive the sludge baffle 16 to rise, so that the sludge channel 13 is opened, so that the sludge is discharged from the sludge channel 13 to the outside of the municipal sewage sedimentation tank 1, so as to collect and treat the sludge. When the sludge inside the municipal sewage sedimentation tank 1 is cleared, the telescopic rod 15 is started to drive the sludge baffle 16 to descend, so that the sludge baffle 16 closes the sludge channel 13 to prevent sewage from flowing out of the sludge channel 13.

[0036] Furthermore, the sludge scraper 1 7 and the sludge scraper 2 12 facilitate scraping of the sludge, which can improve the effect of cleaning the sludge inside the municipal sewage sedimentation tank 1 without manual cleaning. Due to the rotation of the sludge scraper 1 7 and the movable plate 6 and the limitation of the sludge scraper 1 7 by the scraper limit plate 8, the sludge scraper 1 7 can scrape the sludge back and forth, further improving the cleaning effect of the sedimentation tank and improving the practicability of the sedimentation tank.

[0037] The sludge channel 13 is closed by the sludge baffle 16, which facilitates the closing and opening of the sludge channel 13 and the discharge of sludge from the sludge channel 13. This can avoid sewage leakage when the sludge channel 13 is not in use, thereby improving the practicality and convenience of the sedimentation tank.

[0038] Working principle: When using the sewage sedimentation tank, sewage is injected into the municipal sewage sedimentation tank 1. After a period of sedimentation, the sludge will sink to the bottom of the municipal sewage sedimentation tank 1. First, the sewage on the upper layer of the municipal sewage sedimentation tank 1 is pumped out by the sewage pump, and the driving motor 2 is started to drive the threaded rod 5 to rotate. The threaded rod 5 drives the movable plate 6 to slide on the surface of the fixed rod 4. The movable plate 6 drives the sludge scraper 7 and the scraper limit plate 8 to move, so that the sludge scraper 7 scrapes the bottom of the municipal sewage sedimentation tank 1 and scrapes the sludge to the arc bottom surface at the bottom of the municipal sewage sedimentation tank 1.

[0039] Since the scraper limit plate 8 limits the sludge scraper 7, the sludge scraper 7 can scrape the sludge when it is away from the drive motor 2. When the sludge scraper 7 is close to the drive motor 2, the sludge scraper 7 is resisted by the sludge, and the sludge scraper 7 is separated from the scraper limit plate 8. The sludge scraper 7 and the movable plate 6 rotate, which can prevent the sludge from accumulating on the inner wall of the municipal sewage sedimentation tank 1 close to the drive motor 2.

[0040] Then, the driving motor 29 is started to drive the rotating shaft 10 and the connecting rod 11 to rotate, and the connecting rod 11 drives the sludge scraper 2 12 to rotate. The sludge scraper 2 12 scrapes the sludge, and at the same time, the telescopic rod 15 is started to drive the sludge baffle 16 to rise, so that the sludge channel 13 is opened, so that the sludge is discharged from the sludge channel 13 to the outside of the municipal sewage sedimentation tank 1, so as to collect and treat the sludge. When the sludge inside the municipal sewage sedimentation tank 1 is cleared, the telescopic rod 15 is started to drive the sludge baffle 16 to descend, so that the sludge baffle 16 closes the sludge channel 13 to prevent sewage from flowing out of the sludge channel 13.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
