DETAILED DESCRIPTION

[0024] In order to facilitate understanding by those skilled in the art, the present invention is further described below in conjunction with the accompanying drawings.

[0025] like Figure 1-3 The ozone mixing device for sewage treatment shown in the figure comprises a tank body 1, water pipe interfaces 3 are provided at both the upper and lower ends of the tank body 1, a normally closed solenoid valve is installed on the water pipe interface 3, a stirring assembly is installed inside the tank body 1, and a gas mixing mechanism is installed on the stirring assembly. When the stirring assembly rotates, the gas mixing device will rotate together with it, so that the sewage and the ozone sprayed from the gas mixing device are more fully integrated. The tank body 1, the stirring assembly and the gas mixing mechanism are all made of corrosion-resistant materials to avoid being corroded by ozone water and affecting the service life of the device;

[0026] The utility model tank body 1 is provided with a ventilation chamber 4 at the upper end, and a gas pipeline 7 is provided on the ventilation chamber 4, and the gas pipeline 7 can transport ozone into the ventilation chamber 4, and the gas mixing mechanism is rotatably connected with the ventilation chamber 4, and the gas mixing mechanism includes a gas distribution plate 9, and the lower end surface of the gas distribution plate 9 is fixedly connected with the stirring assembly, and the gas distribution plate 9 is provided with a plurality of water through holes 17, and the sewage flowing out from the water pipe interface 3 at the upper end of the tank body 1 can flow downward from the water through holes 17, so as to avoid the sewage being intercepted by the gas distribution plate 9 and affecting the mixing of the sewage and the ozone;

[0027] Specifically, a connecting pipe 8 is installed at the upper end of the gas distribution plate 9, and the upper end of the connecting pipe 8 is rotatably installed in the ventilation chamber 4. An air distribution path 10 is provided inside the gas distribution plate 9. The connecting pipe 8 connects the ventilation chamber 4 and the air distribution path 10 to each other. A plurality of air outlet pipes 12 are provided at the lower end of the gas distribution plate 9.

[0028] Specifically, the lower end of the air outlet pipe 12 is closed, and the upper end of the air outlet pipe 12 is connected to the gas distribution path 10. The air outlet pipe 12 is provided with a plurality of air outlet holes 11 which are vertically equidistantly arranged on the air outlet pipe 12 and close to one side of the tank body 1. The mixing mechanism is installed on the stirring assembly. When the stirring assembly rotates, a vortex is formed in the tank body 1. The sewage is thrown onto the inner wall of the tank body 1 due to the centrifugal force and fully contacts the air outlet holes 11 on the mixing mechanism. The ozone emerging from the air outlet holes 11 can fully contact the sewage, thereby improving the fusion degree of ozone and sewage, thereby improving the sewage treatment effect.

[0029] A vertical scraper 2 is installed on the inner wall of the tank body 1 of the utility model. The vertical scraper 2 can contact the outlet pipe 12.
