Technical Field

[0001] This utility model relates to the technical field of wastewater treatment in lithium niobate wafer processing, specifically to an electrolytic purification device for lithium niobate wafer processing wastewater. Background Technology

[0002] The processing of lithium niobate wafers generates wastewater containing various pollutants. If it is directly discharged or reused, it will easily pollute the environment and affect the quality of wafer processing. Therefore, this type of wastewater needs to be purified.

The device includes a treatment tank and a filter tank. Support frames are installed on both sides of the treatment tank. The stirring mechanism includes a motor and a stirring paddle. The motor is installed on the right side of the treatment tank, and its output is connected to the stirring paddle. Conductive rods are installed at both the top and bottom of the treatment tank. A baffle is installed at the bottom of the treatment tank. An activated carbon adsorption plate is installed below the filter screen. A circulation mechanism is installed at the rear of the filter tank. The pusher mechanism scrapes the surface of the filter screen to prevent residual lithium niobate wafers in the wastewater from clogging it. The circulation mechanism allows for multiple cycles of wastewater filtration, improving the purification effect. The addition of a feed port and valve facilitates control of the flocculant feed rate to prevent affecting the flocculation effect and to prevent waste. However, existing technologies have the problem that simply pushing out the filtered impurities with a push plate is not enough to clean them.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6 The present invention provides the following technical solution: To address the shortcomings of existing technologies that rely solely on push plates to remove filtered impurities, resulting in insufficient cleaning, clogging of the filter screen over long-term use, inconvenience in filter screen replacement, and difficulty in adjusting the pH value of the wastewater as needed, this solution provides an electrolytic purification device for lithium niobate wafer processing wastewater. The device comprises a purification cylinder 1, a purification tank 2, and an inlet pipe 3. The purification tank 2 contains a filtration and purification assembly, including a mounting plate 4 at the front of the purification tank 2, a filter screen 6 fixed to the rear of the mounting plate 4, and an activated carbon purification plate 7. A fixing assembly for limiting positioning is located above the purification tank 2. The filtration and purification assembly is detachable within the purification tank 2 via the fixing assembly. like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the device is powered on, and then an appropriate amount of lithium niobate wafer processing wastewater is added to the purification tank 2 and purification cylinder 1 through the inlet pipe 3. The wastewater is filtered through the filter screen 6 and then adsorbed and purified by the activated carbon in the activated carbon purification plate 7. After filtration and adsorption purification, it enters the purification cylinder 1. The purification cylinder 1 also includes a stirring assembly, which consists of a stirring motor 15 installed at the right end of the purification cylinder 1 and a stirring rod 16 fixedly installed at the output end of the stirring motor 15. An electrode plate 17 is set inside the purification cylinder 1. The electrode plate 17 includes several sets of alternately arranged anode plates and cathode plates. The anode plates are titanium-based lead dioxide coated electrodes, and the cathode plates are stainless steel electrodes. At the same time, the stirring motor 15 and the electrode plate 17 are started by an external controller and power module. The stirring motor 15 drives the stirring rod 16 to stir the wastewater in the purification cylinder 1. Combined with the setting of the electrode plate 17, the wastewater can be fully electrolyzed. In addition, as Figure 6As shown, the pH adjustment component includes a pH sensor 12 installed inside the purification cylinder 1, addition tanks 13 located on the left and right sides of the upper end of the purification cylinder 1, and an addition pump 14 installed at the lower end of the addition tanks 13. The addition tank 13 at the upper left end of the purification cylinder 1 is an acid storage tank, and the addition tank 13 at the upper right end of the purification cylinder 1 is an alkali storage tank. The pH value of the wastewater is detected by the pH sensor 12, and then an appropriate amount of acid or alkali is added to the wastewater in the purification cylinder 1 through the addition pump 14 below the acid or alkali storage tank as needed to neutralize it, thereby adjusting the pH value of the wastewater. After purification is completed, it can be discharged through the drain valve 18. After use, the fixing components are set up, including a fixing rod 8 fixed to the rear end of the purification box 2, a movable plate 9 sleeved on the outside of the fixing rod 8, a fixing plate 10 hinged to the front of the movable plate 9, and a fixing cap 11 for pressing and locking. By rotating the fixing cap 11 threaded to the outside of the fixing rod 8, the fixing cap 11 moves forward and disengages from the movable plate 9, thereby releasing the pressing limit on the movable plate 9. Then, the movable plate 9 moves forward and slides between the movable plate 9 and the fixing rod 8. The movable plate 9 drives the fixing plate 10 to move forward, so that the fixing plate 10 disengages from the mounting plate 4 and the protrusion 5. By flipping the fixing plate 10 upward, the fixing plate 10 rotates between the fixing plate 10 and the movable plate 9. Then, the mounting plate 4, along with the filter screen 6 and the activated carbon purification plate 7, is removed from the purification box 2, which facilitates the disassembly, cleaning, and replacement of the filter purification components. In addition, the bolts between the purification cylinder 1 and the cover plate 19 can be removed, and the cover plate 19 can be removed, which facilitates the maintenance and cleaning of the inside of the purification cylinder 1.
