[0003] After retrieval, the publication number is CN221071164U, which discloses a sewage disinfection and sterilization device. The sewage in the disinfection tank can be disinfected by spraying through a nozzle. By setting an electric slide rail, the nozzle can be driven to move so that the nozzle can evenly spray disinfectant in the disinfection tank. By setting a water inlet pipe, sewage can be added to the disinfection tank. By setting a filter basket, impurities in the sewage can be filtered to prevent the impurities from adhering to the inner wall of the disinfection tank.

[0004] In the process of realizing the present utility model, the inventor found that at least the following problems in the prior art have not been solved. In the above case, the disinfection water is used to disinfect by spraying, and the disinfection water cannot be effectively and evenly mixed with the sewage at the bottom end of the disinfection tank. Moreover, after the filter basket filters the impurities in the sewage, it needs to be manually cleaned by the staff, and the operation is cumbersome.

[0020] In this technical solution, the liquid suction end of the liquid pump 17 is communicated with the corresponding sodium hypochlorite storage tank. Since the liquid guiding pipe 18 is communicated with the connecting pipe 12 through the rotating joint 16, by controlling the liquid pump 17 to work through the corresponding controller, the sodium hypochlorite liquid can be introduced into the connecting pipe 12, and then uniformly discharged into the sterilization chamber 11 through the spraying holes 14 on the outer side of the spraying pipe 13.

[0021] In this embodiment, the filtering mechanism is used for filtering sewage. The filtering mechanism includes a filter plate 21, which is horizontally and fixedly installed on one side inside the filtering chamber 2. The upper end of the connecting pipe 12 is fixedly installed with a strip-shaped cleaning brush 23. The cleaning end of the cleaning brush 23 is attached to the surface of the filter plate 21. A rotating groove 22 is formed through the middle of the filter plate 21. The connecting pipe 12 is rotatably connected to the rotating groove 22.

By controlling the driving motor 15 to work through the corresponding controller, the connecting pipe 12 can be driven to rotate. On the one hand, the connecting pipe 12 can drive the spray pipe 13 to rotate, so as to evenly mix and stir the sewage and the sodium hypochlorite liquid in the sterilization chamber 11, further improving the sterilization efficiency of the sewage. On the other hand, the connecting pipe 12 can drive the cleaning brush 23 to rotate, further automatically cleaning the solid impurities on the surface of the filter plate 21.
