Description
Technical Field
[0001] This utility model relates to the field of photovoltaic glass technology, specifically to a multi-stage purification and treatment equipment for wastewater from photovoltaic glass production. Background Technology
[0002] Photovoltaic glass consists of glass, solar cells, film, back glass, and special metal wires, and has a wide range of applications, such as solar smart windows, solar pavilions, photovoltaic glass building roofs, and photovoltaic glass curtain walls. It is broadly classified into crystalline silicon photovoltaic glass and thin-film photovoltaic glass. The former is further divided into monocrystalline silicon and polycrystalline silicon, and is commonly used as a curtain wall material. During the production of photovoltaic glass, the wastewater generated contains suspended solids, colloidal particles, and trace chemical impurities. However, current multi-stage purification equipment for photovoltaic glass production wastewater relies on manual addition of flocculants, which has large dosage control errors and easily leads to insufficient flocculation or waste of agents. Therefore, we propose a multi-stage purification equipment for photovoltaic glass production wastewater. Utility Model Content

[0022] This technical solution uses a short pipe 13 to deliver flocculant from the flocculant storage tank 8 into the tank 7. The second solenoid valve 12 controls the opening and closing of the short pipe 13. The first liquid level sensor 16 detects the amount of flocculant in the flocculant storage tank 8, facilitating precise feeding.

[0023] Example 2:
[0024] Based on Embodiment 1, this utility model is as follows: Figure 1-3 As shown, a box 10 is fixedly connected to the right end of the top of the placement platform 6. A first filter tank 18 is provided at the left end of the inner cavity of the box 10, and a second filter tank 19 is provided at the right end of the inner cavity of the box 10. Filter screens 20 are provided in the inner cavities of both the first filter tank 18 and the second filter tank 19. A pump 11 is fixedly connected to the left side of the box 10. The suction port of the pump 11 is fixedly connected to the bottom of the right side of the inner cavity of the tank 7 through a pipe. The outlet of the pump 11 is fixedly connected to the top of the inner cavities of the first filter tank 18 and the second filter tank 19 through pipes. A first solenoid valve 9 is provided in the pipe of the outlet of the pump 11. A water quality detector 21 is fixedly connected to the bottom of the inner cavities of the first filter tank 18 and the second filter tank 19. A drain pipe 14 is fixedly connected to the lower part of the back of the filter tank 19. The other end of the drain pipe 14 is fixedly connected to an external drain tank. A battery box 4 is fixedly connected to the top left end of the base plate 1. A storage battery 22 is fixedly connected to the inner cavity of the battery box 4. A toolbox 2 is fixedly connected to the top right end of the base plate 1. A partition is fixedly connected to the inner cavity of the toolbox 2. A display 5 is fixedly connected to the left end of the front of the placement platform 6. The input end of the display 5 is electrically connected to the output end of the first liquid level sensor 16, the second liquid level sensor 17 and the water quality detector 21. A PLC controller 3 is fixedly connected to the middle of the front of the placement platform 6. The output end of the PLC controller 3 is electrically connected to the input end of the first solenoid valve 9, the pump 11, the second solenoid valve 12 and the motor 15.
[0025] This technical solution uses a pump 11 to send flocculated wastewater into the first filter tank 18 and the second filter tank 19. The first solenoid valve 9 controls the opening and closing of the outlet pipe of the pump 11. During operation, the first solenoid valve 9 at the second filter tank 19 is closed. The water quality detector 21 can detect the water quality in the first filter tank 18 and the second filter tank 19. When the water quality deteriorates, it indicates that the filter screen 20 needs to be replaced. In this case, the first solenoid valve 9 at the first filter tank 18 is closed and the first solenoid valve 9 at the second filter tank 19 is opened, allowing wastewater to enter the second filter tank 19. This allows the filter screen 20 to be replaced without shutting down the system.
[0026] The working principle of this utility model is as follows: Flocculant in the flocculant storage tank 8 can be fed into the tank 7 via the short pipe 13. The second solenoid valve 12 controls the opening and closing of the short pipe 13. The first liquid level sensor 16 detects the amount of flocculant in the flocculant storage tank 8, facilitating precise feeding. The motor 15 drives the stirring rod 23 to rotate, ensuring thorough mixing of the flocculant and wastewater. The pump 11 sends the flocculated wastewater into the first filter tank 18 and the second filter tank 19. Solenoid valve 9 can control the opening and closing of the outlet pipe of pump 11. When in use, the first solenoid valve 9 at the second filter tank 19 is closed. When the water quality detector 21 is used, the water quality in the first filter tank 18 and the second filter tank 19 can be detected. When the water quality deteriorates, it means that the filter screen 20 needs to be replaced. Then, the first solenoid valve 9 at the first filter tank 18 is closed and the first solenoid valve 9 at the second filter tank 19 is opened, so that sewage can enter the second filter tank 19, and the filter screen 20 can be replaced without stopping the machine.
