Description

Technical Field

[0001] The present invention relates to the technical field of battery recycling equipment, and in particular to a discharge device for recycling waste lithium batteries. Background Art

[0002] In the battery recycling process, the discharge step is a critical step in the entire processing flow. Its primary purpose is to release any remaining charge in the battery to prevent safety incidents caused by short circuits during subsequent disassembly. Currently, the industry uses salt water immersion to discharge used lithium batteries. A common practice involves mixing a specific proportion of salt water in the immersion tank of the discharge equipment. Once the desired concentration is reached, the used batteries are placed in the tank for centralized discharge. This method is simple to operate and offers rapid processing, but it also has certain technical limitations.

[0003] First, because used batteries vary in shape, size, and remaining charge, if they are all dumped into a soaking tank for centralized discharge, some batteries may reach their discharge cutoff voltage within a short period of time. However, due to the overall operational process, these batteries cannot be removed promptly, and the soaking process must continue until the remaining batteries have completed their discharge. This centralized, unified discharge method not only reduces overall discharge efficiency but may also cause some batteries to over-discharge or incompletely discharge. This directly impacts the recovery rate and quality of valuable metals (such as lithium and cobalt) in the batteries, reducing their reusability.

[0004] At the same time, during the recycling of brine, the effective chlorine components will be gradually consumed due to volatilization and reaction with battery materials. At the same time, the evaporation of water and the continuous accumulation of impurities will cause the brine concentration to gradually decrease. Combined with the centralized treatment method, it will further affect the stability and consistency of the discharge effect.

[0005] To this end, it is necessary to develop a discharge device for recycling waste lithium batteries with differentiated waste battery discharge treatment and real-time control of treatment fluid, so as to achieve an efficient, stable and consistent discharge process, thereby improving the overall recycling efficiency and comprehensive resource utilization rate.

The full gears 2 close to the two ends are engaged with the adjacent driving gear 2 in the same row.

[0013] As an improvement of the above-mentioned solution, the mixing component includes a centralizing frame arranged on one side of the liquid storage frame, a material placing tube is arranged on the top of the centralizing frame, a liquid extraction tube and a liquid infusion tube are arranged on the centralizing frame, both the liquid extraction tube and the liquid infusion tube are equipped with a pump body, and the ends of the liquid extraction tube and the liquid infusion tube are extended into the liquid storage frame for real-time replacement of saline.

[0014] As an improvement to the above solution, it also includes an electric stirring paddle, and the electric stirring paddle is installed in the centralized frame.

[0015] As an improvement of the above solution, it also includes a filter frame and filter plates. A filter frame is provided in the centralized frame and is located below the liquid discharge port of the liquid extraction pipe. The filter plates are symmetrically provided in the filter frame and are distributed obliquely.

[0016] As an improvement to the above scheme, a drying assembly is also included, which includes two groups of mounting plates arranged on both sides of the mounting frame, a nozzle is arranged between the two mounting plates in the same group, and an air pump is also symmetrically installed on the mounting frame, and the air outlet of the air pump is connected to the nozzle on the same side by a connecting pipe.

[0019] Beneficial effects: 1. The present invention realizes differentiated discharge treatment of waste lithium batteries through the coordinated operation of lifting components, loading and unloading components and deployment components; by utilizing a winch and a multi-stage telescopic cylinder in conjunction with an independent immersion frame and a placement frame structure, targeted discharge can be performed on batteries with different residual power conditions, effectively solving the problems of "over-discharge" or "incomplete discharge" existing in traditional centralized immersion methods, and significantly improving discharge efficiency and consistency; at the same time, the loading and unloading components support independent transportation of batteries before and after discharge, providing guarantees for continuous and batch operations, and the deployment components can adjust the brine ratio in real time, and maintain the stability of the electrolyte concentration through a circulating replacement structure, ensuring a consistent electrolyte environment during the discharge process, thereby improving the stability of the discharge effect and the resource recovery rate.

[0036] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present application and are not intended to limit the scope of the present application. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0037] Example: A discharge device for recycling waste lithium batteries, such as Figure 1-Figure 5 、 Figure 9 and Figure 10 Shown, including:

[0038] The liquid storage frame 1, serving as the brine carrier of the entire discharge device, is used to hold the configured brine solution. A mounting frame 11 is fixedly installed between the front and rear sides of the liquid storage frame 1. The mounting frame 11 has a closed top surface structure, and a certain gap is retained between the top panel of the mounting frame 11 and the liquid storage frame 1 to facilitate subsequent immersion operations and gas circulation.

[0039] A hoisting assembly 2 for differentiated hoisting processing includes a hoist 21 installed on the top of the mounting frame 11 in an intermittent arrangement along the front-to-back direction. The rope of the hoist 21 slides through the plate surface of the mounting frame 11, and the ends of the rope of the hoist 21 are respectively fixedly connected to the immersion frame 22. The corresponding immersion frame 22 is driven to achieve lifting movement by the retracting and unreeling action of the hoist 21. The immersion frame 22 is loaded with a placement frame 24 for placing batteries. The placement frame 24 is hollow, and a plurality of groups of multi-stage telescopic cylinders 23 adapted to the number of hoists 21 are arranged on the mounting frame 11. The telescopic ends of the multi-stage telescopic cylinders 23 are connected to adjacent immersion frames 22;

[0040] Furthermore, through the coordinated operation of the aforementioned components, the immersion frame 22, as the core functional unit, is capable of vertical movement, enabling the orderly immersion and lifting of used batteries. Each immersion frame 22 can independently accommodate a placement frame 24 for holding used lithium batteries to be discharged. This split loading design not only enables physical separation and management, but also provides the advantage of differentiated, batched discharge for used batteries with varying residual charges.

[0041] Specifically, the device can classify batteries with similar power states according to the previous power detection results, and load them into corresponding placement frames 24 respectively. Then, their respective immersion frames 22 complete independent and adapted discharge processes in batches. This processing method is different from the traditional centralized salt water immersion method, and effectively avoids the problems of over-discharge or incomplete discharge caused by inconsistent discharge time of various batteries in the same environment, thereby improving the consistency and controllability of the discharge process.

[0042] Furthermore, the placement frame 24 features a hollow structure designed to ensure that the saltwater can fully contact the battery surface, accelerating the electron release reaction process and improving overall discharge efficiency and uniformity. Furthermore, the hollow structure provides a good airflow channel for the subsequent battery drying process, allowing the dry gas to quickly penetrate the gaps between the batteries, significantly accelerating the drying process and reducing the corrosive effects of residual saltwater on battery materials. This helps maintain the material properties of valuable metals (such as lithium, cobalt, and nickel) in the battery, laying a good foundation for subsequent recycling.

[0043] The loading and unloading assembly 3 is used to realize the automatic loading and unloading operation of the battery placement frame 24, thereby improving the automation level and operation efficiency of the entire discharge device. The loading and unloading assembly 3 includes a bracket 31 arranged on the left and right sides of the liquid storage frame 1 and adapted to the number of the immersion frames 22. The brackets 31 are each equipped with an electric roller frame 32, so that the number of the electric roller frame 32 corresponds to the immersion frame 22 one by one, and is used to transport the placement frames 24 loaded with different batches of batteries, so as to ensure that each immersion unit has an independent loading and unloading channel, thereby realizing orderly transportation and accurate positioning of different batches of batteries. At the same time, the bottom of the immersion frame 22 is symmetrically arranged with conveying rollers 33 for rotation. The conveying rollers 33 and the two electric roller frames 32 in the same row are provided with a transmission assembly for contact and cooperation operation. It can be seen that the transmission assembly adopts a contact transmission method, so that when the electric roller frame 32 and the conveying rollers 33 in the same row are in the same horizontal position, they can effectively transmit power to the conveying rollers 33, ensuring that a stable operating state is maintained during the conveying process;

[0044] It is particularly noteworthy that when the immersion frame 22 needs to be immersed in the saline solution for discharge treatment, as the immersion frame 22 is raised or lowered, the transmission assembly will automatically separate, releasing the transmission conveying state. This ensures that before the immersion frame 22 enters the discharge stage, the placement frame 24 has completed positioning and the conveying roller 33 is in a stable non-powered state, avoiding processing hazards caused by power transmission, thereby achieving a smooth transition of the placement frame 24 into the liquid storage frame 1, and keeping the conveying roller 33 in a stable and safe state during the discharge stage.

[0045] It can be seen that the above-mentioned loading and unloading component 3 takes advantage of the left-right symmetrical arrangement, so that the component as a whole supports alternating operations. One side is used for feeding and conveying the batteries to be discharged, and the other side is used for transferring and conveying the discharged batteries, thereby achieving seamless process connection and ensuring that the device can flexibly adjust the operating status according to actual production needs, further enhancing the automation and adaptability of the device.

[0046] A mixing component 4 for adjusting the proportion of brine is provided on the liquid storage frame 1 .

[0047] like Figure 4 and Figure 5As shown, the transmission assembly includes a driving gear 2 321. The driving gear 2 321 is provided at the front and rear ends of the roller body of the electric roller frame 32 close to the conveying roller 33 in the same row. The full gear 1 331 is provided at the front and rear ends of the conveying roller 33. In addition, full gears 2 34 that are meshed with the adjacent full gear 1 331 are arranged at intervals on the left and right sides of the immersion frame 22. The full gears 2 34 close to the two ends are meshed with the adjacent driving gear 2 321 in the same row.

[0048] Specifically, when the electric roller frame 32 is started, the driving gear 2 321 begins to rotate and transmits power to the adjacent full gear 1 331 through the full gear 2 34 engaged therewith, thereby driving the conveying roller 33 to rotate synchronously. This multi-stage gear transmission structure not only ensures the continuity and stability of power transmission, but also adopts a contact transmission method, so that the overall component can adapt to actual changes under different working conditions, ensuring the efficient operation of the entire device.

[0049] like Figure 9 and Figure 10 As shown, the mixing component 4 includes a centralizing frame 41 fixedly arranged on the front side of the liquid storage frame 1, a feeding pipe 42 is arranged on the top of the centralizing frame 41, and a liquid extraction pipe 44 and a liquid infusion pipe 45 are arranged on the centralizing frame 41. The liquid extraction pipe 44 and the liquid infusion pipe 45 are both equipped with a pump body, and the ends of the liquid extraction pipe 44 and the liquid infusion pipe 45 are both extended into the liquid storage frame 1. The water inlet position of the liquid extraction pipe 44 in the liquid storage frame 1 is higher than the water outlet position of the liquid infusion pipe 45, so as to replace the saline in real time.

[0050] like Figure 10 As shown, an electric stirring paddle 43 is also included. The electric stirring paddle 43 is installed in the concentration frame 41 to fully stir the saline solution in the concentration frame 41 to ensure that the newly added salts or other additives can be evenly dispersed in the solution.

[0051] like Figure 10 and Figure 11 As shown, it also includes a filter frame 46 and a filter plate 461. The central frame 41 is provided with a filter frame 46 located below the discharge port of the liquid extraction pipe 44. The filter frame 46 is symmetrically provided with filter plates 461 distributed obliquely. The filter plates 461 are used to filter the used brine extracted from the liquid storage frame 1 to remove impurities and sediments therein to ensure the purity of the re-adjusted brine. At the same time, the filter plates 461 are distributed obliquely so that the intercepted impurities slide along the surface of the filter plates 461 under the action of gravity and finally settle to the bottom of the filter frame 46, effectively preventing impurities from accumulating on the filter plates 461 and causing blockage.

[0052] like Figure 1 、 Figure 12 and Figure 13As shown, a drying assembly 5 is also included, which includes two groups of mounting plates 51 arranged on the left and right sides of the mounting frame 11. A nozzle 52 is provided between the two mounting plates 51 in the same group. An air pump 55 is also symmetrically installed on the mounting frame 11, and the air outlet of the air pump 55 is connected to the nozzle 52 on the same side by a connecting pipe 56.

[0053] like Figure 13 As shown, the drying component 5 also includes a valve 53 arranged in each injection end of the nozzle 52, and each immersion frame 22 is provided with a sensor electrically connected to the valve 53 in the same row. The sensor is used to monitor the position status of the immersion frame 22, and then the opening and closing of the valve 53 is controlled according to the actual discharge situation to ensure that when the placement frame 24 is reset and raised, that is, after the battery discharge process is completed, it can immediately obtain uniform airflow coverage to improve the drying effect; and the nozzle 52 is rotatably connected to the corresponding mounting plate 51, and a drive motor 54 is installed on each side mounting plate 51. The output end of the drive motor 54 is connected to the end of the nozzle 52 on the same side. The drive motor 54 drives the nozzle 52 to rotate, so that the ejected airflow can fully cover the batteries in the placement frame 24, ensuring that the drying process is uniform and thorough, and avoiding the phenomenon of local undrying.

[0054] like Figure 2 、 Figure 4 and Figure 6-Figure 8 As shown, it also includes a guide sleeve 221, a limit plate 222, a stand 223 and a driving gear 224. Guide sleeves 221 are fixedly provided at the upper positions on the left and right sides of the immersion frame 22. Limit plates 222 are slidably provided on the guide sleeve 221, and a protruding end that cooperates with the guide sleeve 221 is provided on the limit plate 222. The protruding end can abut against the corresponding guide sleeve 221 when the limit plate 222 moves to the set position, thereby achieving stable support for the limit plate 222, and a stand 223 is respectively provided on the left and right sides of the top of the immersion frame 22, and a driving gear 224 (an engaging groove is provided on the limit plate 222) that is engaged with the adjacent limit plates 222 is rotated on the stand 223, and tooth grooves 220 that engage with each driving gear 224 are provided on the left and right sides of the mounting frame 11.

[0055] Specific working principle: When in use, first test the power level of the used batteries that need to be discharged, and pack the batteries of the same power range into their respective placement frames 24. Then, inject an appropriate amount of salt water into the liquid storage frame 1. After the preparation work is completed, start the loading and unloading assembly 3 on one side, and place the placement frames 24 loaded with the same batch of batteries in sequence on the electric roller frame 32 on the corresponding side. Then start the electric roller frame 32 to drive the placement frame 24 to move along the conveying path toward the immersion frame 22. In this process, the driving gear 2 321 rotates synchronously with the electric roller frame 32, and engages with the adjacent full gear 2 34, causing the full gear 2 34 at the end position to rotate, and further engages with the adjacent full gear 1 331, causing the full gear 1 331 and the conveying roller 33 thereon to rotate, and so on, so that the multiple conveying rollers 33 on the other side operate synchronously.

[0056] Then, when the placement frame 24 enters the immersion frame 22, it automatically connects to the running conveyor roller 33, ensuring that the placement frame 24 moves stably and is accurately positioned and embedded in the immersion frame 22. After loading is completed, the motorized roller frames 32 on both sides are closed, and the next batch of battery placement frames 24 are placed on the motorized roller frame 32 on the current operating side, preparing for the next cycle of operation.

[0057] The winch 21 is then activated to lower the rope, driving the immersion frame 22 downward. At this point, the full gear 2 34 on the immersion frame 22 separates from the drive gear 2 321, and the multi-stage telescopic cylinder 23 simultaneously telescopes and retracts to coordinately adjust the positional stability of the immersion frame 22. During the downward movement, the drive gear 1 224 meshes and rotates with the corresponding tooth groove 220 as the immersion frame 22 moves, pushing the limit plate 222 down along the guide sleeve 221. When the limit plate 222 reaches its limit position, it blocks and limits the sides of the immersion frame 22, effectively securing the placement frame 24 within it.

[0058] After the immersion frame 22 and placement frame 24 are completely immersed in the salt water, the discharge process begins. After the batch of batteries has been discharged, the winch 21 is restarted to reel in the wires, lifting the immersion frame 22 and placement frame 24. During this process, the full gear 2 34 re-engages with the drive gear 2 321. At the same time, the sensor on the reset immersion frame 22 detects the position change and feeds the corresponding signal back to the control backend. The staff can then transmit the command based on this signal to open the valve 53 and start the air pump 55, directing the airflow into the nozzle 52 and spraying it evenly through each nozzle, thereby drying the residual salt water on the surface of the discharged batteries.

[0059] At the same time, the idle electric roller frame 32 on the other side is activated, repeating the above-mentioned conveying operation, driving the conveying rollers 33 in the same row to operate synchronously. As the immersion frame 22 returns and rises, the drive gear 1 224 re-engages the tooth groove 220, which in turn drives the limit plate 222 to return and move upward. As a result, the limit plate 222 no longer limits the sides of the immersion frame 22, thereby ensuring that the discharged batteries and their placement frame 24 can be stably removed from the immersion frame 22. At the same time, the drive motor 54 on this side is synchronously activated, driving the nozzle 52 to rotate, ensuring that the airflow more evenly covers the surface of the batteries being conveyed. When the placement frame 24 reaches the end of the electric roller frame 32 on this side, it stops and is removed by staff.

[0060] Afterwards, the opposite side electric roller frame 32 is started and the above process is repeated to achieve continuous discharge operation.

[0061] To ensure a stable brine concentration within liquid storage frame 1, materials can be added to concentrating frame 41 via feed pipe 42 as needed, and electric stirring paddle 43 is activated for thorough mixing. Subsequently, a liquid extraction pipe 44 and a liquid infusion pipe 45 work together to extract used brine and replenish it with freshly prepared brine, achieving a circulating water supply. During this process, the recovered brine is filtered and screened by filter frame 46 to remove impurities, ensuring that the circulating water meets quality standards and thus improving the consistency and stability of the discharge effect.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
