[0017] See also Figure 1 , Figure 3 In one embodiment, a new type of sedimentation tank includes a rotating column 1, which is cylindrical and is arranged on the bottom surface of the sedimentation tank body 2 in a vertical direction. A mounting groove 3 is recessed downward on the bottom surface of the sedimentation tank body 2. The lower end of the rotating column 1 is rotatably connected to the mounting groove 3, and its rotating shaft is in the vertical direction. A first motor 4 is provided to drive the rotating column 1 to rotate.

[0018] See also Figure 3 The lower end of the rotating column 1 is provided with a scraper 8 extending radially therefrom, and the other end of the scraper 8 extends to the side wall of the sedimentation tank body 2, and the bottom surface of the scraper 8 is in contact with the bottom surface of the sedimentation tank body 2. As the rotating column 1 rotates, the scraper 8 can scrape the sediment on the bottom surface of the sedimentation tank body 2. Furthermore, one end of the scraper 8 away from the rotating column 1 is set as an arc surface, and contacts the side wall of the sedimentation tank body 2 through the arc surface. In this way, the contact effect is relatively stable.

[0019] See also Figure 3 The bottom surface of the sedimentation tank body 2 is recessed downward and provided with a sewage guide trough 9. In the direction of top view, the sewage guide trough 9 is arranged straight outward along the radial direction of the rotating column 1. One end of the sewage guide trough 9 extends to the rotating column 1, and the other end is connected to the outside of the sedimentation tank body 2. The connection is set to be openable and closable, and the bottom of the sewage guide trough 9 is inclined toward the outside of the sedimentation tank body 2 along the horizontal plane. In this way, when cleaning, the connection of the sewage guide trough 9 is first opened, and then the scraper 8 is driven to rotate by the rotating column 1 to scrape the sediment on the bottom surface of the sedimentation tank body 2 into the sewage guide trough 9, and discharged along the sewage guide trough 9.

[0020] See also Figure 1 In one embodiment, it further comprises a mounting frame 5, one end of which is fixedly connected to the side of the sedimentation tank body 2, the housing of the first motor 4 is fixedly mounted on the mounting frame 5, a pinion 6 is fixedly mounted on the output shaft of the first motor 4, a large gear 7 is fixedly mounted on the upper end of the rotating column 1, the central axis of the large gear 7 coincides with the rotating shaft of the rotating column 1, and the pinion 6 meshes with the large gear 7. In this arrangement, the first motor 4 drives the rotating column 1 to rotate by driving the large gear 7 through the pinion 6, the structure is relatively reasonable and can play a role in deceleration (slow-speed rotation can better ensure the scraping effect of the scraper 8 on the sediment).

[0021] See also Figure 2In one embodiment, an opening and closing plate 10 is rotatably arranged at the connection point between the sewage guide chute 9 and the sedimentation tank body 2, and is driven by a second motor 11. The housing of the second motor 11 is fixed on the outer wall of the sedimentation tank body 2, and the end of its output shaft is fixedly connected to the rotating shaft of the opening and closing plate 10 by welding. This arrangement is structurally reasonable and easy to implement.

[0022] See also Figure 3 In one embodiment, there are two scrapers 8, which are respectively arranged on two opposite sides of the rotating column 1. This arrangement can improve the scraping efficiency.

[0023] See also Figure 3 In one embodiment, preferably, the angle between the bottom of the sewage trough 9 and the horizontal plane is 6°. This arrangement has a reasonable structure, which can allow the sediment entering the sewage trough 9 to slide out along the sewage trough 9 without occupying a large space due to the high slope.
