[0025] Embodiment

[0026] As Figures 1 - 6As shown, a purification and disinfection mechanism for urban sewage includes a disinfection barrel 1. An ultraviolet lamp 8 is fixedly connected to the inner wall of the disinfection barrel 1. It also includes: a cleaning rack 16 arranged in a corrugated shape and attached to the ultraviolet lamp 8, and the cleaning rack 16 is adapted to the ultraviolet lamp 8; a fixed rack 7 fixedly connected to the top of the disinfection barrel 1. A motor 13 is installed on the top of the fixed rack 7. The output end of the motor 13 is fixedly connected to a rotating shaft 14. A stirring rack 15 is fixedly connected to the rotating shaft 14. Among them, the cleaning rack 16 is fixedly connected to the end of the stirring rack 15. A liquid spraying disc 22 is fixedly connected to the top of the stirring rack 15. Liquid spraying holes 23 are formed in the liquid spraying disc 22. A liquid inlet pipe 17 is fixedly connected to the side wall of the disinfection barrel 1, and the liquid inlet pipe 17 is communicated with an external disinfectant storage device. A rotating ring 18 is rotatably connected to the rotating shaft 14. A liquid inlet hole 19 is formed in the position of the rotating shaft 14 opposite to the rotating ring 18. A liquid delivery pipe 20 is fixedly connected inside the rotating shaft 14, and the liquid delivery pipe 20 is communicated with the liquid inlet hole 19. A liquid delivery groove 21 is formed in the stirring rack 15, and the liquid delivery pipe 20 is communicated with the liquid delivery groove 21. The liquid delivery groove 21 is communicated with the liquid spraying disc 22. First collection rings 3 and second collection rings 4 are fixedly connected to the side wall of the disinfection barrel 1 from top to bottom. First sewage discharge doors 5 and second sewage discharge doors 6 are installed on the first collection rings 3 and the second collection rings 4. A coarse filter screen 9 and a fine filter screen 10 are fixedly connected to the disinfection barrel 1 from top to bottom in sequence. The coarse filter screen 9 is arranged inside the first collection ring 3, and the fine filter screen 10 is arranged inside the second collection ring 4. The stirring rack 15 is arranged below the fine filter screen 10. A drain pipe 2 is fixedly connected to the bottom of the disinfection barrel 1. A first cleaning rod 11 is attached to the top of the coarse filter screen 9, and a second cleaning rod 12 is attached to the top of the fine filter screen 10. Both the first cleaning rod 11 and the second cleaning rod 12 are fixedly connected to the rotating shaft 14. The rotating shaft 14 penetrates through the coarse filter screen 9 and the fine filter screen 10 and is rotatably connected to the coarse filter screen 9 and the fine filter screen 10.

[0027] During use, start the motor 13 and simultaneously add the urban sewage to be purified and disinfected into the disinfection barrel 1. When the urban sewage enters the disinfection barrel 1, it first passes through the coarse filter screen 9 to filter out larger impurities in the urban sewage, and then passes through the fine filter screen 10 for secondary filtration of the urban sewage. The filtered urban sewage will enter the space where the ultraviolet lamp 8 is located until the urban sewage completely submerges the ultraviolet lamp 8. During this process, due to the operation of the motor 13, the rotating shaft 14 will be driven to operate, thereby causing the first cleaning rod 11 and the second cleaning rod 12 to rotate, and cleaning the impurities remaining after filtering the urban sewage at the top of the coarse filter screen 9 and the impurities remaining after filtering the urban sewage at the top of the fine filter screen 10 into the first collection ring 3 and the second collection ring 4;

[0028] After the urban sewage completely submerges the ultraviolet lamp 8, start the ultraviolet lamp 8 and make the liquid inlet pipe 17 start to introduce the disinfectant. The disinfectant enters the infusion pipe 20 through the liquid inlet hole 19, then enters the liquid spraying tray 22 through the liquid infusion tank 21, and is sprayed into the urban sewage through the liquid spraying holes 23. During this process, the rotation of the rotating shaft 14 will drive the stirring frame 15 to rotate, thereby causing the liquid spraying tray 22 and the cleaning frame 16 to rotate, so that the liquid spraying holes 23 evenly spray the disinfectant into the urban sewage. The rotation of the cleaning frame 16 will clean the ultraviolet lamp 8. At the same time, the rotation of the stirring frame 15 will mix the urban sewage and the disinfectant, improving the disinfection efficiency of the disinfectant for the urban sewage;

[0029] The cleaning of the ultraviolet lamp 8 is realized, preventing pollutants in the urban sewage from adhering to the ultraviolet lamp 8, affecting the disinfection quality and efficiency of the ultraviolet lamp 8's light on the urban sewage, thereby ensuring the cleanliness of the ultraviolet lamp 8, ensuring the disinfection quality and efficiency of the ultraviolet lamp 8's light on the urban sewage, preventing the ultraviolet lamp 8 from being corroded, and ensuring the service life of the ultraviolet lamp 8.

[0030] As Figures 2 - 4 and Figure 7 As shown, a piston cylinder 25 is fixedly connected to the bottom of the disinfection barrel 1. A piston plate 26 is slidably connected in the piston cylinder 25. An air inlet hole 28 is opened at the top of the side wall of the piston cylinder 25. A one-way valve is installed in the air inlet hole 28, so that the piston cylinder 25 can only draw external air through the air inlet hole 28. The bottom of the rotating shaft 14 is fixedly connected to a reciprocating lead screw 27. The reciprocating lead screw 27 passes through the piston plate 26 and is threadedly connected to the piston plate 26. A rotating chamber 24 is rotatably connected to the inner bottom of the disinfection barrel 1. A gas spraying pipe 29 is fixedly connected to the side wall of the rotating chamber 24. A one-way valve is installed in the gas spraying pipe 29, so that the air in the piston cylinder 25 can only be discharged outward through the gas spraying pipe 29. A gas spraying hole 30 is opened at the bottom of the gas spraying pipe 29. The gas spraying hole 30 is arranged directly opposite to the inner bottom of the disinfection barrel 1. The rotating chamber 24 is fixedly connected to the rotating shaft 14, and the rotating chamber 24 is communicated with the piston cylinder 25.

[0031] During use, the rotation of the rotating shaft 14 will drive the rotation of the rotating bin 24, and further cause the jet pipe 29 to rotate. During this process, the rotation of the rotating shaft 14 will cause the piston plate 26 to move up and down along the inner wall of the piston cylinder 25. When the piston plate 26 moves downward, the piston cylinder 25 will draw in outside air through the air inlet hole 28 into the piston cylinder 25. When the piston plate 26 moves upward, the air in the piston cylinder 25 will enter the jet pipe 29 through the rotating bin 24 and be sprayed through the jet holes 30 onto the inner bottom of the disinfection tank 1, increasing the dissolved oxygen content in the sewage, providing necessary oxidants for microorganisms, thus accelerating the biodegradation process of organic matter in the sewage. At the same time, when air enters the sewage, it can increase the agitation and shear force of the water body through the formation of bubbles, promoting the contact and aggregation between suspended particles and flocculants, forming larger flocs. These flocs are easier to float in the water due to the reduced density, thereby realizing solid-liquid separation, and thus improving the quality and efficiency of sewage purification and disinfection;

[0032] After reaching the treatment time, open the drain pipe 2 to discharge the purified and disinfected sewage in the disinfection tank 1 through the drain pipe 2.

[0033] The above embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model.
