[0027] Among them, the top and bottom ends of the limiting frame 5 are fixedly connected to the limiting slide bar, and the two positioning arc plates 7 are slidably connected to the outside of the limiting slide bar. Through the setting of the limiting slide bar, the displacement of the positioning arc plate 7 can be guided to prevent the positioning arc plate 7 from uncontrollable rotation;

[0028] Embodiment 2:

[0029] See also Figure 1-5, this embodiment provides a technical solution based on the first embodiment: the liquid stirring mechanism 8 includes a hollow shaft 9, a spoiler shaft 10, a spoiler frame 11, an extension frame 12 and a transmission shaft 13, the middle part of the sedimentation tank 1 is vertically rotatably connected with the hollow shaft 9, the inside of the hollow shaft 9 is vertically rotatably connected with the spoiler shaft 10, the bottom end of the spoiler shaft 10 is fixedly connected with the spoiler frame 11, the top of the outer side of the sedimentation tank 1 is fixedly connected with the extension frame 12, the top of the extension frame 12 is vertically rotatably connected with the transmission shaft 13, the middle part of one end of the extension frame 12 is fixedly connected with a transmission motor 14, the output end of the transmission motor 14 and the outer side of the transmission shaft 13 are fixedly connected with a transmission bevel gear 15, and the two transmission bevel gears 15 are meshingly connected;

[0030] The hollow shaft 9 is a hollow structure, and the spoiler shaft 10 is connected inside the hollow shaft 9 through a ball bearing;

[0031] In detail, both ends of the spoiler frame 11 are fixedly connected with a carrying shaft, and the outer sides of the spoiler shaft rod 10 and the carrying shaft are fixedly connected with a liquid stirring piece. By setting the liquid stirring piece, the contact range between the spoiler shaft rod 10 and the spoiler frame 11 and the domestic sewage can be greatly improved, thereby ensuring the liquid stirring effect of the spoiler shaft rod 10 and the spoiler frame 11;
