[0002] The wastewater generated in the production process of new energy batteries contains various harmful substances, such as heavy metal ions, suspended solids and organic pollutants. If it is discharged directly without treatment, it will cause serious harm to the environment and water resources. Traditional wastewater treatment methods often have low filtration efficiency, are prone to blockage, and other problems, making it difficult to meet the requirements of high-precision wastewater treatment.

[0003] The applicant found through retrieval that a battery waste liquid filtration and purification device with high environmental performance has been disclosed in a Chinese patent with publication (announcement) number CN214990856U. This patent mainly uses a preliminary filter screen to filter the larger insoluble substances in the collected battery waste liquid. The wastewater directly hits the filter screen, and the water flow is concentrated in a fixed area, causing excessive local load and easily causing rapid clogging of the filter screen. The single position is subjected to high flow and impurity impact for a long time, which easily leads to local wear or damage of the filter screen, shortens the service life of the filter screen, and cannot uniformly cover the entire filter screen surface, reducing the overall utilization rate of the filter screen. Therefore, we propose a fine filter device for treating new energy battery production wastewater. UTILITY MODEL CONTENT

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.

[0022] Example 1:

[0023] Please see the appendix Figure 1 - Appendix Figure 5A fine filtration device includes a base 1 and a filter structure 2. The filter structure 2 is installed at the top of the base 1. A diversion structure 3 and a fine filtration structure 4 are respectively installed inside the filter structure 2. The diversion structure 3 is located at the top of the fine filtration structure 4. The filter structure 2 includes a filter box 21, which is fixedly installed at the top of the base 1. A drain pipe 22 is fixedly installed at the bottom of the side wall of the filter box 21, and an inlet pipe 23 is fixedly installed at the top of the filter box 21. The diversion structure 3 includes a reciprocating screw 31, a motor 32, and a guide rod 33. The reciprocating screw 31 is rotatably installed inside the filter box 21, and the motor 32 is fixedly installed on the outside of the filter box 21. The motor shaft of the motor 32 is fixedly connected to one end of the reciprocating screw 31. Rods 33 are fixedly installed inside the filter box 21, and guide rods 33 are at both ends of the reciprocating screw 31. Threaded blocks 35 are threadedly installed on the reciprocating screw 31. A diversion box 34 is fixedly installed at the bottom end of the threaded blocks 35. Slider blocks are fixedly installed at the top of both ends of the diversion box 34. The sliders are penetrated by the guide rods 33. The diversion box 34 is slidably connected to the sliders and guide rods 33. A connecting pipe 36 is fixedly connected to the top of the diversion box 34. A telescopic hose 38 is fixedly installed on the connecting pipe 36 through a tee pipe 37. The other end of the telescopic hose 38 is fixedly connected to the water inlet pipe 23. The water inlet pipe 23, telescopic hose 38, tee pipe 37, connecting pipe 36 and the inside of the diversion box 34 are interconnected. A water outlet 39 is provided at the bottom end of the diversion box 34.

[0024] Specifically, the reciprocating screw 31 drives the flow distribution box 34 to move. After the wastewater enters the flow distribution box 34, it is dynamically distributed to various positions of the fine filter plate 43. This avoids the problem of water flow concentration caused by static flow distribution, evenly disperses the water flow, improves the utilization rate of the fine filter plate 43, effectively reduces local blockage and impact pressure, and extends the service life of the fine filter plate 43.

[0025] Example 2:

[0026] Please see the appendix Figure 2 , Figure 5 and attached Figure 6 The fine filter structure 4 includes an installation frame 41 and a fixing block 44. A slide rail is fixedly installed on the inner wall of the filter box 21. Slide grooves 42 are provided on both sides of the installation frame 41. The installation frame 41 is slidably connected to the filter box 21 through the slide grooves 42 and the slide rail. A handle is fixedly installed on one side of the installation frame 41 and on the outside of the filter box 21. A fine filter plate 43 is fixedly installed inside the installation frame 41. The fixing block 44 is fixedly installed on both sides of the diversion box 34. A fixing cylinder 45 is fixedly installed at the bottom end of the fixing block 44. A spring 46 is fixedly installed inside the fixing cylinder 45. A sliding column 47 is fixedly installed at the other end of the spring 46. The sliding column 47 is slidably connected to the inner wall of the fixing cylinder 45. A cleaning brush 48 is fixedly installed at the bottom end of the sliding column 47. The cleaning brush 48 contacts the fine filter plate 43.

[0027] Specifically, the reciprocating movement of the diversion box 34 drives the fixed block 44, which in turn causes the cleaning brush 48 to dynamically clean the fine filter plate 43 through the fixed cylinder 45, spring 46 and sliding column 47, removing impurities attached to the fine filter plate 43, preventing clogging, keeping the fine filter plate 43 unobstructed, and improving filtration uniformity. The spring 46 ensures that the cleaning brush 48 is always in contact with the fine filter plate 43 and maintains appropriate pressure to prevent excessive friction.

[0028] Working principle of this utility model: This utility model is a fine filtration device for treating wastewater from new energy battery production. Wastewater is introduced into the inlet pipe 23, and then flows through the telescopic hose 38, the three-way pipe 37, and the connecting pipe 36 into the distribution box 34. It then sprays out from the outlet hole 39. The motor 32 is started, and its motor shaft drives the reciprocating screw 31 to rotate. The reciprocating screw 31 controls the threaded block 35 to move threadedly. The threaded block 35 drives the distribution box 34 to slide on the guide rod 33 via a slider. This movement of the distribution box 34 disperses the wastewater in the distribution box 34 to various positions on the fine filter plate 43, preventing wastewater from directly flowing into the fine filter plate 43 from the inlet pipe 23, thus reducing the impact of wastewater on the fine filter plate 43. The wastewater is finely filtered through the fine filter plate 43 by the flushing of the position. When the diversion box 34 moves, the diversion box 34 drives the fixed cylinder 45 to move through the fixed block 44, which in turn moves the cleaning brush 48. The cleaning brush 48 sweeps the impurities filtered by the fine filter plate 43, improving the permeability of the fine filter plate 43 and thus improving the filtration effect of the fine filter plate 43. When the cleaning brush 48 moves, the elastic support of the sliding column 47 by the spring 46 ensures that the cleaning brush 48 is always in contact with the surface of the fine filter plate 43. The finely filtered wastewater is discharged through the drain pipe 22. After the wastewater in the filter box 21 is finely filtered, the handle is pulled, and the handle drives the mounting frame 41 to be removed from the filter box 21, making it convenient to clean the fine filter plate 43.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
