[0028] Specifically, photovoltaic wastewater is first poured into filter box 2. The wastewater is initially filtered by the cooperation of the first filter plate 3 and the second filter plate 4. After filtration, the pre-filtered wastewater is injected into reaction tank 1 by opening solenoid valve 5. The wastewater is then defluorinated a second time by the defluorinating agent in reaction tank 1. At this time, motor 7 is turned on to drive turntable 8 to rotate. The first fixed column 9 is rotated by the fixing action of turntable 8 and the first fixed column 9. When the first fixed column 9 rotates, it drives swing block 10 to swing back and forth on the outer wall of second fixed column 11. The swing block 10 is fixed by the toothed block 12 and drives the toothed block 12 to swing. When the toothed block 12 swings, it drives toothed column 13 to move back and forth. The toothed column 13 is fixed by the connecting plate 14 and drives the connecting plate 14 to move back and forth. This stirs the wastewater and defluorinating agent, allowing them to react fully and improving the defluorination efficiency.

[0030] Specifically, the swing block 10 is used to drive the tooth block 12 to swing, and the slide groove 15 is used to limit the running trajectory of the tooth column 13.

[0031] Reference Figures 5-7An outer shell 16 is fixedly connected to the outer wall of the reaction tank 1. A first spring 17 is provided on the inner bottom wall of the outer shell 16. A rotating assembly is provided on the outer wall of the first spring 17. A third fixed post 23 is rotatably connected to the inner wall of the rotating assembly. The outer wall of the third fixed post 23 is fixedly connected to the inner wall of the outer shell 16. A limit block 20 is fixedly connected to the upper surface of the rotating assembly. The outer wall of the limit block 20 is located on the inner wall of the connecting post 21. A second spring 22 is provided on the lower surface of the connecting post 21. The outer wall of the second spring 22 is located on the inner bottom wall of the outer shell 16. A cover plate 25 is fixedly connected to the upper surface of the connecting post 21. A support assembly is provided on the inner wall of the cover plate 25. The lower surface of the support assembly is fixedly connected to the inner wall of the reaction tank 16. The upper surface of the reaction tank 1; the rotating assembly includes a transmission block 18, the outer wall of the first spring 17 is disposed on the lower surface of the transmission block 18, a button 19 is fixedly connected to the upper surface of the transmission block 18, the upper surface of the transmission block 18 is fixedly connected to the lower surface of the limit block 20, and the inner wall of the transmission block 18 is rotatably connected to the outer wall of the third fixed column 23; the support assembly includes a support column 26, the inner wall of the cover plate 25 is rotatably connected to the outer wall of the support column 26, a fixed plate 27 is fixedly connected to the outer wall of the support column 26, and the lower surface of the fixed plate 27 is fixedly connected to the upper surface of the reaction tank 1; the inner wall of the outer shell 16 is fixedly connected to the limit column 24; the outer wall of the second fixed column 11 is fixedly connected to the outer wall of the turntable 8;

[0032] Specifically, pressing button 19, through the fixing action of button 19 and transmission block 18, will drive transmission block 18 to rotate. The first spring 17 is used to reset transmission block 18. When transmission block 18 rotates, through the fixing action of transmission block 18 and limit block 20, it will drive limit block 20 to rotate. When limit block 20 rotates, it is used to fix or release connecting column 21. When connecting column 21 is released, second spring 22 will pop out connecting column 21. Through the fixing action of connecting column 21 and cover plate 25, it will drive cover plate 25 to rotate. Support column 26 and fixing plate 27 cooperate to support the rotation of cover plate 25, thereby realizing the effect of quickly opening cover plate 25 by pressing button 19, which facilitates the operator to monitor the status of wastewater and defluorinating agent in real time.

[0033] Working principle: First, the wastewater is passed through the first filter plate 3 and the second filter plate 4 for preliminary defluorination. After the preliminary defluorination is completed, the solenoid valve 5 is opened to inject the wastewater into the reaction tank 1, so that the wastewater reacts with the defluorinating agent inside the reaction tank 1 for secondary defluorination. After the injection is completed, the motor 7 is turned on to drive the turntable 8 to rotate. When the turntable 8 rotates, it will drive the first fixed column 9 to rotate on the inner wall of the swing block 10, which in turn will drive the swing block 10 to swing back and forth. When the swing block 10 swings, it will drive the toothed block 12 to swing back and forth. Through the meshing relationship between the toothed block 12 and the toothed column 13, when the toothed block 12 swings, it will drive the toothed column 13 to move left and right. When the toothed column 13 moves left and right, it will drive the connecting plate 14 to move left and right back and forth. Through the movement of the connecting plate 14, the wastewater and the defluorinating agent are stirred and mixed, so that the wastewater and the defluorinating agent can react fully, thereby improving the defluorination efficiency.

[0034] Pressing button 19 causes the transmission block 18 to rotate on the outer wall of the third fixed column 23. At this time, the transmission block 18 will compress the first spring 17 and unlock the connecting column 21. After the transmission block 18 unlocks the connecting column 21, the second spring 22 will pop out the connecting column 21, thereby causing the cover plate 25 to rotate on the outer wall of the support column 26. This achieves the effect of quickly opening the cover plate 25 with one click by pressing button 19, which makes it easy for operators to accurately control the defluorination status of wastewater.
