Description

A discharge device for recycling lithium-ion batteries Technical Field

[0001] This utility model relates to the technical field of discharge devices for lithium-ion battery recycling, and in particular to a discharge device for lithium-ion battery recycling. Background Technology

[0002] In recent years, with the increasing global demand for clean energy and the widespread use of electronic devices, lithium-ion batteries have been widely used in many fields due to their significant advantages such as high energy density, long cycle life, and no memory effect. In the electric vehicle sector, lithium-ion batteries, as the core power source, have driven the rapid development of the new energy vehicle industry, effectively reducing dependence on traditional fossil fuels and lowering carbon emissions. In the 3C product (computer, communication, and consumer electronics) market, lithium-ion batteries provide stable and reliable power for devices such as smartphones, laptops, and tablets, meeting people's demand for portable and efficient electronic devices. In addition, in energy storage systems, lithium-ion batteries are also widely used in scenarios such as grid peak shaving and valley filling, and renewable energy grid-connected storage, improving energy utilization efficiency and ensuring the stability of power supply.

[0003] The applicant discovered through a search that a Chinese patent discloses "An Immersion Discharge Device for Recycling Waste Lithium-ion Batteries," with publication (announcement) number "CN216698490U." This patent mainly uses a pipe heater and a temperature control device to heat the salt solution to a set temperature before injecting it into the immersion tank. By heating the salt solution in the pipe, the problem of uneven heating caused by directly heating the immersion tank is solved. However, after repeated recycling, the composition of the salt solution in this patent changes, making it impossible to maintain the reactivity of the salt solution. In actual use, the reactivity of the salt solution may decrease, which will slow down the chemical reaction rate between the lithium-ion battery and the salt solution. Therefore, we propose a discharge device for recycling lithium-ion batteries. Summary of the Invention

[0004] The purpose of this invention is to provide a discharge device for recycling lithium-ion batteries, in order to solve the problem mentioned in the background art that after repeated use of salt solutions, the composition of the salt solution changes and the reactivity of the salt solution cannot be maintained. In actual use, the reactivity of the salt solution may decrease, which in turn slows down the chemical reaction rate between the lithium-ion battery and the salt solution.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a discharge device for lithium-ion battery recycling, comprising an immersion tank, two sets of heating devices are provided on both sides of the inner bottom wall of the immersion tank, a drain pipe is provided on the right outer wall of the immersion tank, a support frame is provided in the middle of the inner bottom wall of the immersion tank, and a discharge assembly is provided inside and on the rear side of the immersion tank. The discharge assembly includes a motor, a fluoroplastic pump, a salt solution tank, an inlet pipe, and a glass plate. The motor is connected to a stirring rod through a drive rod, and the fluoroplastic pump is connected to a spray frame through a delivery pipe. Multiple sets of spray holes distributed at equal intervals are opened on the inner wall of the spray frame.

[0006] As a preferred embodiment, the motor is fixedly installed on the left outer wall of the soaking tank, one end of the drive rod is fixedly connected to the output end of the motor, the other end of the drive rod is rotatably connected to the inner wall of the soaking tank, and the stirring rod is fixedly installed on the outer wall of the drive rod.

[0007] As a preferred embodiment, the outer wall of the drive rod is rotatably connected to the inner wall of the support frame, one end of the delivery pipe is fixedly connected to the output end of the fluoroplastic pump, the other end of the delivery pipe is fixedly connected to the inside of the spray frame, and the spray frame is fixedly installed on the inner wall of the soaking tank.

[0009] As a preferred embodiment, the soaking tank is provided with a placement assembly, which includes a placement frame. A groove is provided on the inner wall of the soaking tank, and a handle is fixedly connected to the top of the placement frame.

[0010] As a preferred embodiment, a connecting plate is fixedly connected to the lower part of the outer wall of the placement frame, and a slider is fixedly connected to the end of the connecting plate away from the placement frame. The outer wall of the slider is slidably connected to the inner wall of the slide groove, and a filter plate is fixedly connected to the inner wall of the placement frame.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Using the set discharge components, the staff starts the motor, which drives the stirring rod to rotate, mixing the salt solution in the soaking tank. This increases the ion movement rate and uniform distribution in the salt solution. At the same time, the heating device ensures that the salt solution in the soaking tank is heated evenly. After the salt solution in the soaking tank has been used for a certain period of time, the staff opens the drain pipe to drain the old salt solution from the tank. Then, the fluoroplastic pump is started to transport the salt solution from the salt solution tank to the soaking tank. This maintains the reactivity of the salt solution and continuously creates a good environment for the battery recycling reaction.

[0013] 2. With the placement components, the operator can hold the handle at the top of the placement frame and use the sliding cooperation between the slider and the inner wall groove of the soaking tank to smoothly place the placement frame on the top of the support frame. This design makes it easy and precise for the operator to put the placement frame into or take it out of the soaking tank. The filter plate can effectively prevent residues and impurities that fall off the battery surface from contacting the battery. Attached Figure Description

[0021] 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.

[0022] Please refer to Figures 1 and 3-5. A discharge device for lithium-ion battery recycling includes an immersion tank 1. Two sets of heating devices 2 are arranged on both sides of the inner bottom wall of the immersion tank 1. A drain pipe 3 is arranged on the right outer wall of the immersion tank 1. A support frame 4 is arranged in the middle of the inner bottom wall of the immersion tank 1. A discharge assembly 5 is arranged inside and at the rear of the immersion tank 1. The discharge assembly 5 includes a motor 501, a fluoroplastic pump 504, a brine tank 508, an inlet pipe 509, and a glass plate 510. The motor 501 is connected to a stirring rod 503 through a drive rod 502. The fluoroplastic pump 504 is connected to a spray frame 506 through a delivery pipe 505. Multiple sets of spray holes 507 are evenly distributed on the inner wall of the spray frame 506. The motor 501 is fixedly installed. On the left outer wall of the soaking tank 1, one end of the drive rod 502 is fixedly connected to the output end of the motor 501, and the other end of the drive rod 502 is rotatably connected to the inner wall of the soaking tank 1. The stirring rod 503 is fixedly installed on the outer wall of the drive rod 502, and the outer wall of the drive rod 502 is rotatably connected to the inner wall of the support frame 4. One end of the conveying pipe 505 is fixedly connected to the output end of the fluoroplastic pump 504, and the other end of the conveying pipe 505 is fixedly connected to the inside of the spray frame 506. The spray frame 506 is fixedly installed on the inner wall of the soaking tank 1. The liquid inlet pipe 509 is fixedly installed on the top of the salt solution tank 508. The glass plate 510 is fixedly installed on the outer wall of the salt solution tank 508. The input end of the fluoroplastic pump 504 is fixedly connected to the inner wall of the salt solution tank 508.

[0023] The stirring rod 503 will not interfere with the support frame 4 during rotation. A glass plate 510 is provided to facilitate direct viewing of the remaining solution in the salt solution tank 508. The top two sides of the support frame 4 are hollow, while the middle part is solid.

[0024] Specifically, through the discharge component 5, the operator starts the motor 501, which drives the stirring rod 503 to rotate via the drive rod 502, mixing and stirring the salt solution in the soaking tank 1. This increases the ion movement rate and uniform distribution in the salt solution. At the same time, the heating device 2 ensures that the salt solution in the soaking tank 1 is heated evenly. After the salt solution in the soaking tank 1 has been used for a period of time, the operator opens the drain pipe 3 to drain the old salt solution from the tank. Then, the fluoroplastic pump 504 is started to transport the salt solution in the salt solution tank 508 to the soaking tank 1. This maintains the reactivity of the salt solution and continuously creates a good environment for the battery recycling reaction.

[0025] Please refer to Figures 1, 2, and 6. The soaking tank 1 is equipped with a placement component 6, which includes a placement frame 602. A groove 601 is provided on the inner wall of the soaking tank 1. A grip plate 603 is fixedly connected to the top of the placement frame 602. A connecting plate 604 is fixedly connected to the lower part of the outer wall of the placement frame 602. A slider 605 is fixedly connected to the end of the connecting plate 604 away from the placement frame 602. The outer wall of the slider 605 is slidably connected to the inner wall of the groove 601. A filter plate 606 is fixedly connected to the inner wall of the placement frame 602.

[0026] When the stirring rod 503 rotates, it will not interfere with the support frame 4. A glass plate 510 is installed on the salt solution tank 508. Through this glass plate 510, the remaining amount of solution in the tank can be intuitively and conveniently monitored. The filter plate 606 is located in the middle of the inner wall of the placement frame 602. When the lithium-ion battery placed on top reacts chemically with the salt solution, residues and impurities will fall off the surface of the battery. At this time, the filter plate 606 can let these residues and impurities fall to the inner bottom wall of the placement frame 602, effectively preventing the lithium-ion battery from coming into contact with the residues and impurities again.

[0027] Specifically, through the placement component 6, the operator holds the top grip plate 603 of the placement frame 602, and by the sliding cooperation between the slider 605 and the inner wall groove 601 of the soaking tank 1, the placement frame 602 can be placed on top of the support frame 4. This design makes it easy and precise for the operator to put the placement frame 602 into or take it out of the soaking tank 1. The filter plate 606 on the inner wall of the placement frame 602 can prevent residues and impurities that fall off the battery surface from contacting the battery.

[0028] The working principle of this utility model is as follows: This utility model is a discharge device for recycling lithium-ion batteries. First, the operator starts the motor 501, which drives the drive rod 502 to rotate. The rotation of the drive rod 502 drives the stirring rod 503 to rotate, which mixes and stirs the salt solution in the soaking tank 1. Then, the operator starts the heating device 2, which, together with the above stirring operation, ensures that the salt solution inside the soaking tank 1 is heated evenly. After a period of use, the operator can open the drain pipe 3 to drain the old salt solution from the tank. Subsequently, the fluoroplastic pump 504 is started to transport the salt solution from the salt solution tank 508. At pipe 505, the salt solution is transported to the spray hole 507 on the inner wall of the spray frame 506 through the delivery pipe 505. Then, the salt solution is transported to the interior of the soaking tank 1 through the spray hole 507. Finally, the operator can hold the top handle 603 of the placement frame 602 and slide the slider 605 with the sliding groove 601 on the inner wall of the soaking tank 1. When the slider 605 slides to the bottom of the groove 601, the placement frame 602 is just at the top of the support frame 4. When the lithium-ion battery is placed on the top of the placement frame 602 and reacts chemically with the salt solution, the filter plate 606 can make the residue and impurities that fall off the surface of the battery fall to the bottom wall of the interior of the placement frame 602.

[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.
