[0026] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0027] like Figures 1 to 5 As shown in the figure, a wastewater treatment device for photovoltaic cell production in one embodiment of the present invention includes a neutralization tank 1. An inlet pipe 11 and an overflow pipe 12 are welded on the neutralization tank 1. The height of the overflow pipe 12 is lower than that of the inlet pipe 11. Wastewater flows into the neutralization tank 1 from the inlet pipe 11 and flows out from the overflow pipe 12 after neutralization.

[0028] A reagent tank 2 is installed on the top cover of the neutralization tank 1. The reagent tank 2 contains neutralizing agent. A reagent tube 21 is welded to the reagent tank 2. The reagent tube 21 passes through the top cover of the neutralization tank 1 and is inserted into the water inlet pipe 11. An opening and closing component is sealed on the end of the reagent tube 21 away from the reagent tank 2.

[0029] Specifically, when wastewater flows into neutralization tank 1 from inlet pipe 11, the opening and closing components on the reagent pipe 21 are opened, and the neutralizing agent in reagent tank 2 and the wastewater in inlet pipe 11 are mixed and then flow into neutralization tank 1 together.

[0030] like Figure 2 , Figure 4 and Figure 5 As shown, the inlet pipe 11 is L-shaped, and the opening of the inlet pipe 11 inside the neutralization tank 1 is perpendicular to the ground. The opening of the reagent pipe 21 is located inside the vertically downward pipe of the inlet pipe 11. The opening and closing assembly includes a blocking plate 22, which blocks the opening of the reagent pipe 21 at the end away from the reagent tank 2. A sliding post 23 is integrally formed on the blocking plate 22, and a groove 211 matching the sliding post 23 is provided on the reagent pipe 21.

[0031] Specifically, the blocking plate 22 blocks the opening of the medicine tube 21, preventing the medicine in the medicine tank 2 from flowing out of the medicine tube 21. When the wastewater flows through the inlet pipe 11, the wastewater impacts the blocking plate 22 under the action of gravity, pulling the spring 231 to slide downward in the slide groove 211. The blocking plate 22 moves away from the medicine tube 21, and the neutralizing agent flows out of the medicine tube 21 to neutralize the wastewater in the inlet pipe 11.

[0032] When wastewater is no longer being supplied to the neutralization tank 1 through the inlet pipe 11, in order to re-seal the agent pipe 21 through the blockage plate 22, a spring 231 is welded onto the sliding column 23. The end of the spring 231 away from the sliding column 23 is welded to the bottom wall of the trough 211.

[0033] Specifically, when the wastewater no longer impacts the blockage plate 22, the retraction force of the spring 231 pulls the blockage plate 22, causing it to block the opening of the reagent tube 21.

[0034] Because the blocking plate 22 is plate-shaped, in order to better seal the medicine tube 21, a sealing block 221 is integrally formed on the blocking plate 22, and the inner diameter of the sealing block 221 matches the inner diameter of the medicine tube 21.

[0035] Specifically, when the blocking plate 22 is attached to the opening of the medicine tube 21, the sealing block 221 is inserted into the medicine tube 21 to enhance the sealing effect of the medicine tube 21 and prevent the neutralizing agent in the medicine container 2 from leaking out.

[0036] Furthermore, a first through hole 222 is provided on the plug plate 22, which penetrates both the plug plate 22 and the sealing block 221. A connecting frame 25 is welded to the inner wall of the reagent tube 21, and a sealing plug 251 matching the first through hole 222 is welded to the connecting frame 25. When the plug plate 22 is attached to the opening of the reagent tube 21, the sealing plug 251 is inserted into the first through hole 222. When the water inlet pipe 11 conveys wastewater into the neutralization tank 1, the plug plate 22 moves away from the reagent tube 21, and the sealing plug 251 also separates from the first through hole 222. The neutralizing agent in the reagent tank 2 flows out from the first through hole 222 after passing through the reagent tube 21.

[0037] It is worth noting that when the wastewater flow rate in the inlet pipe 11 is small, the small water flow impact on the plug plate 22 may not be able to separate the sealing plug 251 and the first through hole 222. In order to ensure that the neutralizing agent in the agent tube 21 can flow out, an annular plate 24 is welded on the plug plate 22. A water storage tank is formed between the plug plate 22, the annular plate 24 and the agent tube 21. A second through hole 223 matching the water storage tank is opened on the plug plate 22.

[0038] Specifically, the wastewater in the inlet pipe 11 falls into the storage tank. The accumulation of water in the storage tank makes the blockage plate 22 heavier, causing the spring 231 to stretch and move the blockage plate 22 away from the reagent tube 21, ensuring the reagent can flow out through the first through hole 222. When the inlet pipe 11 stops supplying wastewater to the neutralization tank 1, the wastewater in the storage tank gradually leaks into the neutralization tank 1 through the second through hole 223. The spring 231 elastically contracts, the blockage plate 22 moves upward, and the first through hole 222 is sealed by the sealing plug 251.

[0039] like Figure 2 and Figure 3 As shown, a fixed box 3 is welded to the inner wall of the neutralization tank 1, and the water inlet pipe 11 is inserted into the fixed box 3. Multiple mixing plates 31 are welded to the inner wall of the fixed box 3, and the mixing plates 31 are symmetrically welded to the inner wall of the fixed box 3.

[0040] Specifically, the wastewater flowing out from the inlet of the inlet pipe 11 already contains a neutralizing agent. This wastewater containing the neutralizing agent hits multiple mixing plates 31, which makes the neutralizing agent more uniform in the wastewater and enhances the mixing efficiency of the wastewater.

[0041] Because a large amount of foam is generated during the neutralization of acidic and alkaline wastewater, this foam can clog subsequent water treatment pipes and equipment, affecting the normal operation of wastewater treatment. To ensure the normal operation of subsequent equipment, the outlet of the fixed box 3 is lower than the overflow pipe 12. Specifically, since the wastewater levels in the neutralization tank 1 and the fixed box 3 are the same, and the foam floats on the surface, the foam is confined within the fixed box 3 and will not overflow from the overflow pipe 12, thus ensuring the normal operation of subsequent equipment.

[0042] To eliminate foam inside the fixing box 3, the wastewater treatment device for photovoltaic cell production also includes a water tank 4. A water pump 41 is installed on the water tank 4, and a water supply pipe 42 is connected to the water pump 41. The end of the water supply pipe 42 away from the water pump 41 is inserted into the neutralization tank 1. The end of the water supply pipe 42 inserted into the neutralization tank 1 is threadedly connected to a water distribution box 43, and a spray nozzle 431 is opened on the water distribution box 43.

[0043] Specifically, the water in the water tank 4 contains defoamer, and the water distribution box 43 is at a higher level than the overflow pipe 12. The water containing defoamer in the water tank 4 is pumped by the water pump 41 into the water distribution box 43, and then sprayed out through the spray nozzle 431 to eliminate the foam in the fixed box 3.

[0044] Furthermore, the water distribution box 43 is located below the mixing plate 31 on the left side. Water falling from the inlet pipe 11 will not be blocked by the mixing plate 31 and will not hit the water distribution box 43, thus protecting the water distribution box 43.

[0045] During operation, wastewater flows from the inlet pipe 11 into the neutralization tank 1, impacting the blockage plate 22. The impact pulls the sliding column 23 downwards, moving the blockage plate 22 away from the reagent pipe 21. This allows the neutralizing agent in the reagent tank 2 to flow out from the reagent pipe 21 and mix evenly with the wastewater in the inlet pipe 11. After being mixed with the neutralizing agent, the wastewater falls from the inlet pipe 11, striking the mixing plate 31 and enhancing the mixing effect before falling into the neutralization tank 1. The wastewater in the neutralization tank 1 overflows from the overflow pipe 12 and flows to the next wastewater treatment process, thus enabling continuous wastewater treatment.

[0046] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
