[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panels (modules), controllers and inverters. The main components are composed of electronic components. After the solar cells are connected in series and packaged for protection, they can form large-area solar cell modules. Combined with power controllers and other components, photovoltaic power generation devices are formed. Using the photovoltaic effect, sunlight is irradiated on silicon materials to generate current and directly generate electricity. The industrial chain formed by the application and development of silicon materials is called "photovoltaic industry", including the production of high-purity polysilicon raw materials, solar cell production, and solar cell module production. Photovoltaic wastewater mainly comes from the cleaning and drainage of polysilicon production lines and diffusion furnaces, the drainage of acid-base waste gas washing devices, and the drainage of silane combustion tower-ammonia absorption devices.

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The above structure enables the fluorine-containing wastewater to enter the interior of the containing tank body 110 from the liquid inlet pipe 120, and the containing tank body 110 begins to store liquid. When the liquid level inside the containing tank body 110 is flush with the top of the stirring mechanism 200, the power switch of the power mechanism 300 is started, and the power mechanism 300 drives the stirring mechanism 200 to stir the fluorine-containing wastewater, so that the fluorine-containing wastewater and the reagent are fully and evenly mixed, thereby causing the solid impurities inside the containing tank body 110 to sink. The power mechanism 300 drives the stirring mechanism 200 to operate while driving the transmission mechanism 400 to operate. The operation of the transmission mechanism 400 drives the pipeline mechanism 500 to operate, thereby discharging the solid impurities and floating impurities to the designated area. The above structural design enables the overall footprint of the device to be greatly reduced. At the same time, the entire sedimentation and filtration process is fast and convenient. The preliminary precipitation of solid impurities, the salvage of floating impurities, and the preliminary filtration of the fluorine-containing wastewater are completed through one device.

[0045] The first connecting ring 220 is driven to rotate by the connecting column 210, thereby driving the first worm wheel blade 230, so that a vortex is formed at the bottom of the container body 110, so that the settled solid impurities are moved closer to the center, which is convenient for the subsequent absorption by the pipeline mechanism 500. The connecting column 210 drives the first connecting ring 220 to rotate while driving the stirring blade 240 to rotate, so that the fluorine-containing wastewater and the reagent are fully stirred. The connecting column 210 drives the stirring blade 240 to rotate while driving the second worm wheel blade 260 to rotate through the second connecting ring 250, so as to drive the liquid surface at the top of the container body 110 to form a vortex, thereby bringing the floating impurities inside the container body 110 closer to the center, so as to facilitate the subsequent absorption by the pipeline mechanism 500.

[0047] After the driving motor 310 is started, its output end drives the first gear plate 320 to rotate, and the rotation of the first gear plate 320 drives the second gear plate 330 to rotate, thereby driving the third gear plate 360 ​​to rotate, and the rotation of the second gear plate 330 drives the third gear plate 360 ​​to rotate while driving the fixing bolt 340 to rotate, and the rotation of the fixing bolt 340 drives the connecting column 210 to rotate, and the rotation of the third gear plate 360 ​​drives the rotating plate 410 to rotate.

[0048] Please refer to Figure 7 and Figure 8The transmission mechanism 400 includes a rotating disk 410 connected to the bottom end of the third gear disk 360, a driving rod 420 is installed at the bottom end of the rotating disk 410, a swinging disk 430 is provided on the outer wall of the driving rod 420, a guide groove matching the driving rod 420 is provided inside the swinging disk 430, a moving frame 440 is assembled at one end of the swinging disk 430, a limiting block 450 is installed on the outer wall of the moving frame 440, the top of the limiting block 450 is fixedly assembled on the bottom end of the sealing disk 140, the moving frame 440 is U-shaped as a whole, another set of limiting blocks 450 are assembled at the end of the moving frame 440, a limiting hole matching the moving frame 440 is provided inside the limiting block 450, a driving rod 460 is provided at the bottom end of the moving frame 440, and a piston disk 470 is installed at the bottom end of the driving rod 460;

The horizontal movement of the swing disk 430 drives the moving frame 440 to move, thereby driving the driving rod 460 to move. The movement of the driving rod 460 drives the piston disk 470 to move.

[0050] Please refer to Figures 1 to 9 The pipeline mechanism 500 includes a first suction pipe part 510 that matches the mud discharge port at the bottom end of the sealing disk 140. A worm wheel disk 520 is installed at the input end of the first suction pipe part 510. A clearance groove is opened on the outer wall of the first suction pipe part 510. A sealing corrugated strip 540 is installed inside the clearance groove. A solid discharge pipe 530 is connected to one side of the first suction pipe part 510. A conductive pipe part 550 is connected to one end of the first suction pipe part 510. The top of the conductive pipe part 550 is connected to one end of a return spring 560.

[0052] When the piston disc 470 moves toward the conductive tube portion 550, the piston disc 470 squeezes the liquid inside the conductive tube portion 550, so that the liquid inside the conductive tube portion 550 squeezes the piston member, thereby stretching the sealing bellows and driving the piston cylinder to move forward to block the entrance of the suction float tube 590. When the piston disc 470 is reset, that is, when the piston disc 470 moves in the opposite direction of the conductive tube portion, the piston cylinder moves backward to compress the sealing bellows, and at the same time, the floating impurities on the upper liquid surface of the container tank body 110 are sucked into the second suction tube portion 580 together with the water, and then enter the suction float tube 590 and are discharged to the designated position.

[0057] Step 4: precipitation, stirring to make the medicine and the fluorine-containing wastewater evenly mixed, so that the impurities in the fluorine-containing wastewater are precipitated and reduced;

[0058] Step 5: solid removal. When the power mechanism 300 drives the stirring mechanism 200 to operate, it also drives the transmission mechanism 400 to operate.
