Description

Technical Field

[0001] This utility model relates to the field of lithium battery technology, and in particular to a lithium battery waste residue soaking solution filtration device. Background Technology

[0002] During the production of lithium batteries, a large amount of lithium battery waste residue is generated. After soaking treatment, the resulting soaking solution often contains a variety of impurities, including solid particles and dissolved organic matter.

[0003] Most lithium battery waste residue leaching solution filtration devices use a single filter screen or a few fixed filter screens for filtration. When faced with lithium battery waste residue leaching solutions with complex composition and high impurity content, a single filter screen is very easy to clog, resulting in a significant decrease in filtration efficiency. Even filtration devices using multiple fixed filter screens usually have the filter screens fixedly installed, making it difficult to clean them in real time. As the usage time increases, impurities continuously accumulate on the surface and in the pores of the filter screen, thereby reducing the filtration effect of the leaching solution. Therefore, we propose a lithium battery waste residue leaching solution filtration device. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a lithium battery waste residue soaking solution filtration device. This device can solve the problem that most lithium battery waste residue soaking solution filtration devices use a single filter screen or a few fixed filter screens for filtration. When a single filter screen is used to deal with lithium battery waste residue soaking solution with complex composition and high impurity content, it is very easy to get clogged, which leads to a significant decrease in filtration efficiency. Even if a filtration device uses multiple fixed filter screens, the filter screens are usually fixed and difficult to clean in real time. As the usage time increases, impurities continue to accumulate on the surface and in the pores of the filter screen, thereby reducing the filtration effect of the soaking solution.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a lithium battery waste residue soaking solution filtration device, comprising:

[0027] Waste residue filter box 1, with a sealing cover 7 bolted to the top of the waste residue filter box 1;

[0028] Waste residue filtration structure, which is located on waste residue filtration box 1;

[0029] The waste residue filtration structure includes a third filter plate 11, a second filter plate 13, a first filter plate 14, and four rotating tubes 5. The top of the waste residue filtration box 1 is provided with three mounting slots 10. The third filter plate 11, the second filter plate 13, and the first filter plate 14 are all slidably installed inside the corresponding mounting slots 10. The four rotating tubes 5 are all rotatably connected inside the waste residue filtration box 1. Both ends of the four rotating tubes 5 rotatably extend to the outside of the waste residue filtration box 1. A support plate 2 is fixedly connected to one side of the waste residue filtration box 1. An electric push rod 3 is fixedly installed on the top of the support plate 2. A toothed plate 4 is fixedly connected to the telescopic end of the electric push rod 3. The toothed plate 4 is slidably connected to the top of the support plate 2. Toothed rings 6 are fixedly sleeved on the outer surface of the four rotating tubes 5. The four toothed rings 6 are all meshed with the toothed plate 4.

[0030] The waste residue filtration structure also includes a water tank 9, a water pump 12, and a water supply pipe 8. The water tank 9 is fixedly connected to the side of the waste residue filter box 1 away from the electric push rod 3. The water pump 12 is fixedly installed on the top of the water tank 9. The water supply pipe 8 is fixedly connected to the side of the waste residue filter box 1 near the water tank 9. The pumping end of the water pump 12 is connected to the inside of the water tank 9, and the draining end of the water pump 12 is connected to the inside of the water supply pipe 8. The ends of the four rotating pipes 5 away from the electric push rod 3 all rotate and extend into the inside of the water supply pipe 8. All four rotating pipes 5 are connected to the inside of the water supply pipe 8. Multiple nozzles 16 are fixedly connected to the outer surface of each of the four rotating pipes 5. All multiple nozzles 16 are connected to the inside of the corresponding rotating pipe 5.

[0031] A liquid inlet pipe 17 is fixedly connected to one side of the waste residue filter box 1, and a liquid outlet pipe 18 is fixedly connected to the side of the waste residue filter box 1 away from the liquid inlet pipe 17. Both the liquid inlet pipe 17 and the liquid outlet pipe 18 are connected to the interior of the waste residue filter box 1. Two sealing rings 15 are fixedly fitted on the outer surface of each of the four rotating pipes 5. The multiple sealing rings 15 are in contact with the interior and exterior of the water supply pipe 8 respectively. A control panel is fixedly installed on the side of the waste residue filter box 1 near the electric push rod 3.

[0032] Furthermore, when using this device, specifically the lithium battery waste residue soaking solution filtration device, the lithium battery waste residue soaking solution is injected into the waste residue filter box 1 through the inlet pipe 17. The soaking solution passes sequentially through the third filter plate 11, the second filter plate 13, and the first filter plate 14. Through multi-layer filtration, the outer skin and particulate impurities in the waste residue soaking solution are gradually intercepted and filtered. The filtered liquid is discharged from the drain pipe 18, completing the physical filtration operation. Subsequently, the physically filtered soaking solution is transported to the subsequent purification treatment through the drain pipe 18. When it is necessary to clean the filter screen, the electric push rod 3 is activated. The telescopic end of the electric push rod 3 drives the toothed plate 4 to slide on the top of the support plate 2. Since the toothed plate 4 is meshed with the toothed rings 6 on the outer surface of the four rotating tubes 5, the movement of the toothed plate 4 will drive the rotating tubes 5 to rotate in the waste residue filter box 1, so that multiple nozzles 16 can be directed toward the third filter plate 11, the second filter plate 13, and the first filter plate 14 respectively.

[0033] The water pump 12 is started, and water is drawn from the water tank 9 and delivered to the four rotating pipes 5 through the water supply pipe 8. Multiple nozzles 16 fixedly connected to the outer surface of the rotating pipes 5 spray water out. As the rotating pipes 5 rotate, the nozzles 16 can wash the sides of the third filter plate 11, the second filter plate 13 and the first filter plate 14 in all directions, washing away the impurities attached to the surface and pores of the filter plates, thus achieving automatic cleaning of the filter screen. The sealing ring 15 on the outer surface of the rotating pipes 5 is in close contact with the water supply pipe 8 to prevent water leakage during the washing process, thereby periodically cleaning the impurities inside the waste residue filter box 1, ensuring that the filter screen will not be clogged before cleaning.

[0034] This device is equipped with a third filter plate 11, a second filter plate 13, and a first filter plate 14 to form a multi-layer filtration structure. Different filter plates can intercept impurities such as outer skin and particulate matter of different particle sizes, forming a graded filtration, thereby dispersing the impurity interception pressure. Through the meshing connection between the toothed plate 4 and the four toothed rings 6, the four water supply pipes 8 can cooperate with the corresponding multiple nozzles 16 to achieve all-round automatic rinsing of both sides of the three filter plates. Before impurities accumulate and clog the filter screen pores, they are flushed away in time, keeping the filter screen transparent and further improving the filtration effect of the waste residue soaking solution.
