[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 5 This utility model provides a technical solution: a disinfectant distribution structure for sewage treatment, a disinfection tank 1, an inlet pipe 4 fixedly connected to the left side of the disinfection tank 1, an outlet pipe 5 fixedly connected to the right side of the disinfection tank 1, an inner cylinder 15 fixedly connected to the inner bottom wall of the disinfection tank 1, the inlet pipe 4 passing through the side wall of the disinfection tank 1 and communicating with the inner cylinder 15, a top cover 6 detachably installed on the top of the disinfection tank 1, a rotating shaft 18 inserted into the inner cylinder 15 is installed in the middle of the top cover 6 through a bearing, and stirring plates 19 are evenly distributed on the outer side of the rotating shaft 18;

[0025] A dispersing hole 20 is provided in the middle of the stirring plate 19. A high-pressure pipe 11 is movably connected to the top of the rotating shaft 18 through a sealed bearing. A support frame 12 for fixing the high-pressure pipe 11 is provided in the middle of the top of the top cover 6. A liquid channel 25 connecting the dispersing hole 20 and the high-pressure pipe 11 is provided inside the rotating shaft 18 and the dispersing hole 20. A sterilization box 7 is provided on one side of the top of the top cover 6. A high-pressure pump 24 of the high-pressure pipe 11, which is connected to the high-pressure pipe 11, is provided on one side of the top of the sterilization box 7.

[0026] A motor 3 is fixedly connected to the bottom center of the disinfection tank 1. The output shaft of the motor 3 passes through the bottom wall of the disinfection tank 1 and is inserted into the inner cylinder 15. The output shaft of the motor 3 is fixedly connected to a spline shaft 23. A spline hole is opened at the bottom of the rotating shaft 18. Both the spline hole and the end of the spline shaft 23 are provided with chamfers to facilitate docking.

[0027] In this embodiment, the power cord is plugged into the power socket, and the motor 3 and high-pressure pump 24 start working after being powered on. The output shaft of the motor 3 drives the spline shaft 23 to rotate. The sewage enters the inner cylinder 15 through the inlet pipe 4 after being pressurized. The high-pressure pump 24 is turned on through the switch panel 9. As the liquid level of the sewage inside the inner cylinder 15 continues to rise, the stirring plate 19 also rotates inside the inner cylinder 15 to stir the sewage. At the same time as stirring, the high-pressure pump 24 pumps out the disinfectant, which is then dispersed into the sewage through the high-pressure pipe 11 and the medicine channel 25 and then through the dispersing hole 20. This allows the stirring of sewage and the dispersing of disinfectant to be carried out simultaneously, thereby improving the efficiency of disinfectant dispersing.

[0028] As the sewage level rises further, the sewage overflows from the top of the inner cylinder 15 to the surrounding areas, further mixing the sewage and accelerating the mixing of disinfectant and sewage. Finally, the mixed sewage is discharged from the outlet pipe 5.

[0029] Specifically, a filling pipe is provided on one side of the top of the disinfection box 7, and a filling cap 8 is threadedly connected to the top of the filling pipe. A switch panel 9 is provided in the middle of the top of the disinfection box 7, and a pump box 10 is provided outside the high pressure pump 24.

[0030] In this embodiment, the motor 3 is connected to the socket using a separate power cord to control the start and stop of the motor 3. The switch panel 9 is connected to the socket using another power cord to control the start and stop of the high-pressure pump 24. The switch panel 9 can control the high-pressure pump 24 to start working and pump the disinfectant into the high-pressure pipe 11. When the disinfectant in the disinfection box 7 is insufficient, disinfectant can be added into the disinfection box 7 by unscrewing the filling cap 8.

[0031] Specifically, the top of the top cover 6 has three hanging rings 13 arranged in a ring array. The top cover 6 and the sterilization tank 1 are connected by bolts 14. The bottom circumference of the sterilization tank 1 is provided with support legs 2.

[0032] Specifically, a sludge tray 21 is placed on the inner bottom wall of the inner cylinder 15. A round hole is opened in the center of the sludge tray 21. Two material picking plates 22 are symmetrically arranged at the top center of the sludge tray 21. A drain valve 17 is provided on the side wall of the inner cylinder 15 near the water outlet pipe 5.

[0033] In this embodiment, the top cover 6 and the disinfection tank 1 can be separated by unscrewing the bolt 14. The top cover 6 can be lifted by hanging it on the lifting ring 13 with a hook, and the stirring plate 19 can be taken out from the inner cylinder 15. Then, the sewage in the inner cylinder 15 can be drained by manually opening the drain valve 17, and the sludge tray 21 can be taken out by manually grasping the material picking plate 22 to clean the sediment.

[0034] Specifically, the height of the inner cylinder 15 is less than the height of the inner wall of the disinfection tank 1, and the upper side wall of the inner cylinder 15 is provided with overflow holes 16 in a ring array.

[0035] In this embodiment, since the height of the inner cylinder 15 is less than the height of the inner wall of the disinfection tank 1, the sewage inside the inner cylinder 15 can overflow smoothly from the top of the inner cylinder 15. By setting the overflow hole 16, the overflowing sewage can be made to spray outward in the form of a water column, so as to further mix the sewage and spread the disinfectant.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
