[0001] This application relates to the field of battery recycling technology, specifically to a battery dismantling and recycling system. Background Technology

[0002] With the rapid development of new energy sources, people are paying increasing attention to the recycling and disposal of new energy power batteries. Existing recycling and disposal methods for new energy power batteries are prone to causing pollution and cannot fully recover battery materials.

[0003] Therefore, a new solution is urgently needed to address the problems in the existing technology. Utility Model Content

[0004] This application addresses the aforementioned shortcomings of the prior art by providing a battery dismantling and recycling system, the specific solution of which is shown below:

[0005] A battery dismantling and recycling system includes: an underwater cutting module for providing an aquatic environment and cutting the battery in the aquatic environment; a shell-core separation device for separating the battery casing and the battery cell; a battery cell drying device; a core separation device; and a water circulation system.

[0006] The material outlet of the underwater cutting module is connected to the material inlet of the shell-core separation device;

[0007] The cell outlet of the core-shell separation device is connected to the cell inlet of the cell drying device; the outer shell outlet of the core-shell separation device outputs the battery outer shell.

[0008] The material outlet of the battery cell drying device is connected to the material inlet of the core separation device; the material outlet of the core separation device outputs battery cell material.

[0009] The output end of the water circulation system is connected to the inlet of the underwater cutting module, and the input end of the water circulation system is connected to the outlet of the underwater cutting module, so as to recover the electrolyte generated by the underwater cutting module and circulate the water in the underwater cutting module.

[0010] In some specific embodiments, the underwater cutting processing module includes a waterjet cutter and a main water tank;

[0011] The main water tank provides the aquatic environment, and part or all of the waterjet cutter is located in the main water tank for cutting the battery in the aquatic environment. The inlet and outlet of the underwater cutting module are located on the main water tank. In a specific application, the waterjet cutter is used to cut off the top and bottom parts of a single battery cell underwater. At this time, the electrolyte in the battery can directly enter the water without waste.

[0012] In one specific embodiment, the material outlet of the underwater cutting module is located on the waterjet cutter or on the main water tank.

[0013] In one specific embodiment, the solubility of the electrolyte in the liquid in the main water tank is detected. When the solubility of the electrolyte reaches a preset threshold, the liquid in the main water tank is transported to the water circulation system through the outlet.

[0014] In some specific embodiments, a casing packing machine is also included; the casing packing machine is connected to the casing discharge port of the casing-core separation device and is used to pack the battery casing. In practical applications, the casing-core separation device obtains the cut-off battery from the material outlet of the waterjet cutter, separates the battery cell from the casing, transfers the cell to the cell drying device, and transfers the casing to the casing packing machine. In practical applications, the battery casing includes an aluminum casing, and the casing packing machine includes an aluminum casing packing machine. After the aluminum casing is packed by the aluminum casing packing machine, the recycling of the aluminum casing can be completed.

[0015] In practical applications, since the underwater cutting module processes the battery underwater, there may be cases where the battery cells, after being separated by the core-shell separation device, still contain water and electrolyte. In subsequent processing, it is still necessary to remove the water and electrolyte from the battery cells. Therefore, a battery cell drying device is used to dry the battery cells. In some specific embodiments, an electrolyte condenser is also included. The electrolyte condenser is installed on the battery cell drying device and is connected to the liquid inlet of the underwater cutting module to collect the liquid in the battery cell drying device and transport the collected liquid to the underwater cutting module.

[0016] During the drying process, the cell drying device evaporates the water and electrolyte contained in the cell to the electrolyte condenser, which then transports them to the underwater cutting module so that the water circulation system can process the water and electrolyte.

[0017] In a specific application, the battery cells obtained after drying in the cell drying device further enter the core separation device. The core separation device stabilizes the cells and separates the separator, positive electrode sheet, and negative electrode sheet. These are then sent out of the battery dismantling and recycling system through the separator outlet, positive electrode sheet outlet, and negative electrode sheet outlet, respectively. The separator material obtained here can be directly packaged and sold, while the positive and negative electrode sheets can be processed in-house and sold.

[0018] In some specific embodiments, the water circulation system includes: a secondary water tank, a centrifuge, a centrifugal storage tank, a distillation unit, a condensation unit, a transfer water tank, and a water storage tank connected in sequence;

[0019] The auxiliary water tank is connected to the liquid outlet of the underwater cutting module to obtain the liquid in the underwater cutting module; the auxiliary water tank is used to temporarily store the liquid output from the main water tank and / or the waterjet cutter and transport it to the centrifuge.

[0020] The water storage tank is connected to the inlet of the underwater cutting module to replenish water to the underwater cutting module. In one specific embodiment, the main water tank is connected to the water storage tank through the inlet. The water storage tank stores water purified by distillation. The water storage tank delivers the purified water to the main water tank through the inlet to replenish the main water tank and refresh the water in the main water tank.

[0021] In some specific embodiments, a centrifugal pump is also included, which is disposed at least at one of the following locations: between the auxiliary water tank and the centrifuge, between the centrifuge and the centrifugal storage tank, between the centrifugal storage tank and the distillation unit, between the condensation unit and the transfer water tank, and between the transfer water tank and the storage tank.

[0022] In some specific embodiments, the centrifuge is equipped with a waste outlet for discharging the waste generated by the centrifuge. A centrifugal pump can be used to pump liquid from the auxiliary water tank to the centrifuge. After centrifugation, centrifugal liquid and centrifugal waste are obtained. The centrifugal waste may contain a small amount of positive and negative electrode materials, which can be further dried and extracted for recycling. The centrifugal liquid enters the centrifugal storage tank and is then pumped by the centrifugal pump to a distillation unit for distillation to obtain water and electrolyte, respectively. The water can be transferred to a transfer tank and / or a storage tank for further processing in the next stage of the cycle.

[0023] In practical applications, the water in the main water tank and the auxiliary water tank is centrifuged by a centrifuge and then temporarily stored as centrifugal liquid in a centrifugal storage tank. After filtering out the centrifugal waste, the water is further purified by a distillation unit to obtain water and electrolyte, respectively, thus achieving the separation and recycling of water and electrolyte.

[0024] In some specific embodiments, the distillation apparatus is provided with an electrolyte outlet for discharging electrolyte; after the distillation apparatus collects electrolyte, it can be discharged through the electrolyte outlet for subsequent sale, thereby realizing the recovery and recycling of electrolyte.

[0025] In some specific embodiments, the condensing device is provided with a cooling water outlet, a cooling water inlet, and a condensate outlet; the intermediate water tank is connected to the condensate outlet, the cooling water outlet, and the cooling water inlet respectively, and is used to circulate cooling water for the condensing device and store the water produced by the condensing device.

[0026] In practical applications, the water produced at the cooling outlet is the water used for heat exchange with high-temperature steam in the condenser. Therefore, the water produced at the cooling outlet is at a relatively high temperature. In practical applications, it can be further cooled through pipeline design or other cooling device design. On the other hand, the water flowing out of the condenser outlet is the water obtained by condensing high-temperature steam through the condenser, and its temperature is relatively low.

[0027] Furthermore, a portion of the water in the transfer tank flows back to the condenser through the cooling inlet of the condenser to achieve a condensation effect; the other portion of the water in the transfer tank enters the storage tank for further storage. When the water in the main tank is transported to the centrifuge, the water in the main tank decreases, and the storage tank replenishes the main tank, replacing and updating the water in the main tank, ultimately realizing the recycling of water resources in the battery dismantling and recycling system.

[0028] In some specific embodiments, a conveying device is also included;

[0029] The material outlet of the underwater cutting module is connected to the material inlet of the shell-core separation device through a conveying device;

[0030] The cell outlet of the shell-core separation device is connected to the cell inlet of the cell drying device via a conveying device;

[0031] The material outlet of the battery cell drying device is connected to the material inlet of the core separation device via a conveying device.

[0032] In some specific embodiments, the conveying device includes a conveyor belt capable of stably transporting materials such as batteries.

[0033] In one specific embodiment, a feeding mechanism is also included. The feeding mechanism, underwater cutting module, shell-core separation device, cell drying device, and core separation device are connected in sequence via a conveying device, and the battery being processed includes a lithium iron phosphate single cell battery.

[0034] Beneficial Effects: This application provides a battery dismantling and recycling system, including an underwater cutting module, a core-shell separation device, a cell drying device, a core-winding separation device, and a water circulation system. By setting up an underwater cutting module to cut the battery underwater, and then using a water circulation system to treat the water containing electrolyte, the electrolyte and water can be separated and water resources can be recycled. At the same time, by setting up the core-shell separation device, the cell drying device, and the core-winding separation device, the battery can be completely dismantled and the various components in the battery can be fully utilized, which greatly improves the recycling efficiency of battery resources, saves industrial costs, significantly reduces environmental pollution, and improves economic benefits.

[0046] Example

[0047] This embodiment provides a battery dismantling and recycling system that can reduce environmental pollution during battery recycling and improve recycling efficiency. The specific solution is as follows:

[0048] A battery dismantling and recycling system includes: an underwater cutting module 1 for providing an aquatic environment and cutting the battery in the aquatic environment; a shell-core separation device 2 for separating the battery casing and the battery cell; a battery cell drying device 3; a core separation device 4; and a water circulation system 5.

[0049] The material outlet of underwater cutting module 1 (e.g.) Figure 2 As shown in Figure 1b) and the material inlet of the shell-core separation device 2 (e.g. Figure 1 (As shown in Figure 2a) Connected;

[0050] The cell outlet of the core-shell separation device 2 (e.g.) Figure 1 (as shown in Figure 2b) and the cell inlet of the cell drying device 3 (as shown in Figure 2b) Figure 1 (As shown in 3a) connected; the outer shell outlet of the core-shell separation device 2 (as shown in 3a) Figure 1 The casing of the output battery is shown in Figure 2c.

[0051] The material outlet of the battery cell drying device 3 (e.g. Figure 1 (as shown in Figure 3b) and the material inlet of the core separation device 4 (e.g.) Figure 1 (As shown in 4a) Connected; the material outlet of the core separation device 4 outputs the battery cell material; wherein, the material outlet of the core separation device 4 includes a positive electrode plate outlet 41, a negative electrode plate outlet 42 and a diaphragm outlet 43.

[0052] The output of the water circulation system 5 is connected to the inlet of the underwater cutting module 1 (e.g., Figure 2 As shown in Figure 1d), the input end of the water circulation system 5 is connected to the outlet of the underwater cutting module 1 (as shown in Figure 1d). Figure 2 As shown in Figure 1c, the electrolyte generated by the underwater cutting module 1 is recovered, and the water in the underwater cutting module 1 is circulated.

[0053] The connection diagrams of each module are shown below. Figure 1 and Figure 4 As shown, in a specific application process, the battery that needs to be disassembled is fed into the underwater cutting module's material inlet (e.g., Figure 1 As shown in Figure 1a, the battery enters and passes through the shell-core separation device 2, the cell drying device 3, and the winding core separation device 4 in sequence, finally completing the complete disassembly of the battery.

[0054] In some specific embodiments, the underwater cutting module includes a waterjet cutter 11 and a main water tank 12. The main water tank 12 provides an aquatic environment, and part or all of the waterjet cutter 11 is located in the main water tank 12 for cutting the battery in the aquatic environment. The inlet and outlet of the underwater cutting module 1 are located on the main water tank 12. In a specific application, the waterjet cutter 11 is used to cut off the upper and lower parts of a single battery cell in water. At this time, the electrolyte in the battery can directly enter the water without waste.

[0055] In one specific embodiment, the material outlet of the underwater cutting module 1 is located on the waterjet cutter 11 or the main water tank 12. In practical applications, the solubility of the electrolyte in the liquid in the main water tank 12 is detected. When the solubility of the electrolyte reaches a preset threshold, the liquid in the main water tank 12 is transported to the water circulation system 5 through the outlet of the main water tank 12, so that the electrolyte can be extracted through the water circulation system 5, and the water used in the extraction process is recycled back to the main water tank 12.

[0056] After being segmented by the underwater cutting module 1, the electrolyte is recovered through the water circulation system 5, and the remaining material is transported to the core-shell separation device 2 to separate the received material from the outer shell. The separated core is then transported to the core drying device 3 for drying. The dried core is then transported to the core-winding separation device 4 for further separation, such as separating the positive electrode, negative electrode, and separator. The outer shell obtained from the separation process can be recycled and packaged.

[0057] In some specific embodiments, a casing baler 21 is also included for better recycling and packaging of the battery casing. The casing baler 21 is connected to the casing discharge port of the casing-core separation device 2 and is used to package the battery casing. In practical applications, the casing-core separation device 2 obtains the cut-off battery from the material outlet of the waterjet cutter 11, separates the battery cell from the casing, transfers the cell to the cell drying device 3, and transfers the casing to the casing baler 21. In practical applications, the battery casing includes an aluminum casing, and the casing baler 21 includes an aluminum casing baler. After the aluminum casing is packaged by the aluminum casing baler, the recycling of the aluminum casing can be completed.

[0058] In practical applications, since the underwater cutting module 1 processes the battery underwater, there may be cases where the battery cells separated by the core-shell separation device 2 still contain water and electrolyte. In subsequent processing, it is necessary to remove the water and electrolyte from the battery cells. Therefore, the battery cell drying device 3 dries the battery cells. In some specific embodiments, to better recover the water and electrolyte generated during the drying operation, an electrolyte condenser 31 is also included. The electrolyte condenser 31 is installed on the battery cell drying device 3 and is connected to the liquid inlet of the underwater cutting module 1 to collect the liquid in the battery cell drying device 3 and transport the collected liquid to the underwater cutting module 1. The liquid outlet of the electrolyte condenser 31 is as follows: Figure 1 As shown in Figure 1f.

[0059] During the drying process, the cell drying device 3 evaporates the water and electrolyte contained in the cell to the electrolyte condenser 31, which then transports them to the underwater cutting module 1 so that the water circulation system 5 can process the water and electrolyte.

[0060] In a specific application, the battery cells obtained after drying in the battery cell drying device 3 further enter the core separation device 4. The core separation device 4 separates the battery cells, obtaining a separator, a positive electrode sheet, and a negative electrode sheet. These are then sent out of the battery dismantling and recycling system through the positive electrode sheet outlet 41, the separator outlet 43, and the negative electrode sheet outlet 42, respectively. The separator material obtained here can be directly packaged and sold, while the positive and negative electrode sheets can be processed and sold after further processing. Figure 5 and Figure 6 The connection relationships between the various modules and the output diagram are shown.

[0061] In some specific embodiments, the water circulation system 5 includes: a secondary water tank 51, a centrifuge 52, a centrifugal storage tank 53, a distillation device 54, a condensation device 55, a transfer water tank 56, and a water storage tank 57 connected in sequence; the secondary water tank 51 is connected to the liquid outlet of the underwater cutting module 1 to obtain the liquid in the underwater cutting module 1; the secondary water tank 51 is used to temporarily store the liquid output from the main water tank 12 and / or the water jet cutter 11, and transport it to the centrifuge 52.

[0062] The water storage tank 57 is connected to the inlet of the underwater cutting module 1 to replenish water to the underwater cutting module 1. In one specific embodiment, the main water tank 12 is connected to the water storage tank 57 through the inlet. The water storage tank 57 stores water purified by distillation by the distillation device 54. The water storage tank 57 delivers the purified water to the main water tank 12 through the inlet to replenish the main water tank 12 and refresh the water in the main water tank 12, thereby realizing water circulation in the main water tank 12 and ensuring that the water level in the main water tank 12 is maintained at a certain position so that the underwater cutting module 1 can work normally.

[0063] In some specific embodiments, such as Figure 1 As shown, it also includes a centrifugal pump 7, which is installed at least at one of the following locations: between the auxiliary water tank 51 and the centrifuge 52; between the centrifuge 52 and the centrifugal storage tank 53; between the centrifugal storage tank 53 and the distillation unit 54; between the condensation unit 55 and the transfer water tank 56; and between the transfer water tank 56 and the water storage tank 57. The centrifugal pump 7 facilitates the extraction of water and electrolyte from the main water tank and provides the power for the circulation of water and electrolyte.

[0064] In some specific embodiments, the centrifuge 52 is provided with a waste outlet 521 for discharging centrifugal waste generated by the centrifuge 52. The centrifugal pump 7 can be used to pump liquid from the auxiliary water tank 51 to the centrifuge 52. After centrifugation, centrifugal liquid and centrifugal waste are obtained. The centrifugal waste may contain a small amount of positive and negative electrode materials, which can be further dried and extracted for recycling. After the centrifugal liquid enters the centrifugal storage tank 53, it is then pumped by the centrifugal pump 7 to the distillation unit 54 for distillation to obtain water and electrolyte, respectively. The water can be transferred to the transfer water tank 56 and / or the storage tank 57 for the next stage of the cycle. The connection relationships between the main modules and the main outputs of the dismantling and recycling system are as follows: Figure 5 As shown.

[0065] In practical applications, the water in the main water tank 12 and the auxiliary water tank 51 is centrifuged by the centrifuge 52 and then temporarily stored as centrifugal liquid in the centrifugal storage tank 53. After filtering out the centrifugal waste, it is further distilled by the distillation device 54 to finally separate the water from the electrolyte, thus realizing the recycling of water resources and greatly reducing the environmental pollution generated during the recycling process.

[0066] In some specific embodiments, the distillation apparatus 54 is provided with an electrolyte outlet 541 for discharging electrolyte; after the distillation apparatus 54 collects electrolyte, it can be discharged through the electrolyte outlet 541 for subsequent external sale, so as to realize the recovery and recycling of electrolyte.

[0067] In one specific embodiment, a reboiler 58 is also included connected to the distillation apparatus 54. The reboiler 58 provides heat to the liquid at the bottom of the distillation apparatus 54 to vaporize it, maintaining the gas-liquid balance and heat balance within the distillation apparatus 54. This promotes liquid circulation within the distillation apparatus 54, accelerates the gas-liquid exchange frequency, and improves the separation efficiency for the electrolyte and water. In one specific embodiment, the distillation apparatus 54 includes a distillation column.

[0068] In some specific embodiments, the condenser 55 is provided with a cooling water outlet (e.g. Figure 3 As shown in 5c), cooling water inlet (as shown in 5c) Figure 3 (as shown in Figure 5a) and condensate outlet (as shown in Figure 5a) Figure 3 (As shown in Figure 5b); the intermediate water tank 56 is connected to the condensate outlet, the cooling water outlet and the cooling water inlet respectively, and is used to circulate cooling water for the condensation device 55 and store the water produced by the condensation device 55.

[0069] In practical applications, the water produced at the cooling outlet is the water used for heat exchange with high-temperature steam in the condenser 55. Therefore, the water produced at the cooling outlet has a relatively high temperature, which can be further cooled through pipeline design or other cooling device design. The water flowing out of the condenser outlet is the water obtained by condensing high-temperature steam through the condenser 55, and has a lower temperature. In one specific embodiment, the condenser 55 includes a total condenser.

[0070] Furthermore, a portion of the water in the transfer tank 56 flows back to the condenser 55 through the cooling inlet of the condenser 55 to achieve a condensation effect; the other portion of the water in the transfer tank 56 enters the storage tank 57 for further storage. When the water in the main tank 12 is transported to the centrifuge 52, the storage tank 57 replenishes the main tank 12, replacing and updating the water in the main tank 12, ultimately realizing the recycling of water resources in the battery dismantling and recycling system.

[0071] In some specific embodiments, such as Figure 1 As shown, it also includes a conveying device 6; the material outlet of the underwater cutting module 1 is connected to the material inlet of the shell-core separation device 2 via the conveying device 6; and / or the cell outlet of the shell-core separation device 2 is connected to the cell inlet of the cell drying device 3 via the conveying device 6; and / or the material outlet of the cell drying device 3 is connected to the material inlet of the core separation device 4 via the conveying device 6. In some specific embodiments, the conveying device 6 includes a conveyor belt, which can stably transport materials such as batteries.

[0072] In one specific embodiment, a feeding mechanism 8 is also included. The feeding mechanism 8, the underwater cutting module 1, the shell-core separation device 2, the cell drying device 3, and the winding core separation device 4 are connected in sequence via a conveying device 6, and the battery being processed includes a lithium iron phosphate single cell battery.

[0073] This embodiment provides a battery dismantling and recycling system, including an underwater cutting module, a core-shell separation device, a cell drying device, a core-winding separation device, and a water circulation system. By using the underwater cutting module to cut the battery underwater, and then treating the water containing electrolyte through the water circulation system, the electrolyte and water can be separated, and water resources can be recycled. Simultaneously, by incorporating the core-shell separation device, the cell drying device, and the core-winding separation device, the battery can be completely dismantled, and its components can be fully utilized. The overall recycling system has a high degree of automation, greatly improving the recycling efficiency of battery resources. The recycled materials have high purity, resulting in high economic benefits and significantly reducing environmental pollution. It is a green and environmentally friendly recycling system.
