Description

Technical Field

[0001] This invention relates to the field of battery recycling technology, and more specifically, to a battery colloid dismantling device and dismantling method. Background Technology

[0002] Currently, for battery packs encapsulated with a large amount of structural adhesive, the industry mainly uses physicochemical methods based on solvent action for disassembly. These methods typically rely on the chemical penetration and reaction capabilities of the adhesive solvent to reduce or disable the adhesive bonding strength through dissolution, swelling, or softening, thereby achieving separation of the battery cell from the casing or between the battery cell and the casing.

[0003] However, due to the large quantity and wide distribution of structural adhesives in battery packs, and their certain chemical resistance, existing processes often require a large amount of debonding solvents to ensure dismantling efficiency and thoroughness. This leads to a significant increase in the cost per process and generates a large amount of adhesive-containing waste liquid, resulting in complex subsequent treatment and significant environmental pressure. In addition, most dismantling environments are not sufficiently enclosed, and solvents are prone to volatilization and dispersion during the operation, causing not only material loss but also safety risks such as the accumulation of flammable and toxic vapors. Overall, the operation is not economically viable or controllable. Summary of the Invention

[0025] The following detailed description, through embodiments and in conjunction with the accompanying drawings, details the overall structure, working principle, and technical effects of the battery colloid disassembly equipment provided by the present invention, as well as the detailed steps, implementation principles, and technical effects of the supporting disassembly method.

[0026] Please refer to Figure 1 and Figure 2 This invention provides a battery adhesive dismantling device 100 and a dismantling method, applicable to the field of new energy vehicle battery recycling, specifically for battery packs that use a large amount of structural adhesive for bonding and potting. This device aims to efficiently, economically, and safely dismantle the structural adhesive within the battery pack, enabling separation of the battery cells from the casing 10 and between the battery cells themselves.

[0027] This battery gel disassembly equipment 100 includes a housing 10, a support platform 20, a solvent circulation system 30, and a heating device 40.

[0028] A support platform 20 is disposed within the housing 10 for supporting the battery pack 201. The support platform 20 includes at least one liftable movable platform 21. Solvent circulation passes through a solvent storage device 31, a solvent driving device 32, a solvent pool 33, and a spray device 34. The solvent storage device 31 stores solvent. The solvent pool 33 is disposed at the bottom of the housing 10. The spray device 34 is disposed above the support platform 20. The solvent driving device 32 drives the solvent in the solvent storage device 31 to selectively transport to the solvent pool 33 and / or the spray device 34. A heating device 40 heats the solvent in the solvent pool 33.

[0029] Specifically, the housing 10 forms a working chamber, providing a sealed space for disassembly operations. A closable, sealed door (not shown in the figure) is provided on the front of the housing 10 to facilitate the insertion and removal of the battery pack 201. A support platform 20 is disposed within the internal space of the housing 10 to support the battery pack 201 to be disassembled. The support platform 20 includes at least one liftable movable platform 21, and a lifting mechanism corresponding to the movable platform 21 is provided inside the housing 10, such as a hydraulic cylinder, electric push rod, or lead screw module, to drive the movable platform 21 to rise and fall.

[0030] It is understood that the solvent driving device 32 is used to selectively deliver the solvent in the solvent storage device 31 to the solvent pool 33 and / or the spray device 34. That is, the solvent in the solvent storage device 31 can be delivered only to the solvent pool 33, or only to the spray device 34, or simultaneously to both the solvent pool 33 and the spray device 34.

[0031] During operation, the battery pack 201 is placed on the support platform 20. Depending on the distribution, thickness, and type of the structural adhesive used in the battery pack, the operator or control system can decide which mode to use, such as immersion, fumigation, spraying, or a combination of these modes. For immersion mode, the movable platform 21 is lowered, immersing the battery pack in the liquid solvent tank 33. For fumigation mode, the heating device 40 heats the solvent in the solvent tank 33, causing the solvent to evaporate and the steam to fill the interior of the housing 10, fumigating the battery pack. For spraying mode, the solvent driving device 32 pumps the solvent to the spraying device 34, spraying the battery pack below.

[0032] This invention enables a single device to be compatible with three chemical dismantling processes. Users do not need to configure separate equipment for each process, which improves the versatility of the equipment and space utilization, and reduces investment costs.

[0033] Specifically, the heating device 40 can be one or a combination of various structures such as electric heating tube, hot plate or liquid heating coil. The present invention does not limit the specific type of heating device 40.

[0034] Furthermore, the support platform 20 includes at least one fixed platform 22 and one movable platform 21. The fixed platform 22 is fixedly installed inside the housing 10, and the movable platform 21 is located below the fixed platform 22 and at the bottom of the housing 10. It is understood that the battery packs on the fixed platform 22 can undergo fumigation and spraying operations, while the battery packs on the movable platform 21 can undergo immersion operations in addition to fumigation and spraying. This allows the equipment to process battery packs with different needs or at different dismantling stages in parallel within a single work cycle, significantly improving capacity and flexibility.

[0035] Furthermore, the spraying device 34 includes multiple spray pipes 341 corresponding to the fixed platform 22 and the movable platform 21, respectively, with multiple spray heads 342 spaced apart on each spray pipe 341. The spraying device 34 includes multiple independent spray pipe paths 341. Specifically, an upper layer of spray pipes 341 is provided corresponding to the upper fixed platform 22, and a lower layer of spray pipes 341 is provided corresponding to the lower movable platform 21. Multiple spray heads 342 are spaced apart along the length of each spray pipe 341. Specifically, each spray pipe 341 can be controlled by an independent valve (not shown in the figure).

[0036] By controlling the valves on different spray pipes 341, independent and precise spraying of the upper and lower battery packs can be achieved. For example, spraying can be applied only to the upper layer, only to the lower layer, or simultaneously. The multiple spray heads 342 arranged at intervals ensure that the solvent can uniformly cover the upper surface of the battery pack, avoiding incomplete disassembly caused by insufficient local spraying and enhancing the precision of process control.

[0037] To enable solvent recycling, the battery colloid dismantling equipment 100 also includes a solvent filtration device 36. The solvent driving device 32 is also used to drive the solvent in the solvent pool 33 through the solvent filtration device 36 and back to the solvent storage device 31. The solvent driving device 32 performs a recycling function, transporting used waste liquid containing colloid residues and other impurities from the solvent pool 33 to the solvent filtration device 36, where it is filtered and purified before being returned to the solvent storage device 31, forming a closed-loop cycle.

[0038] It is important to note that the solvent composition in solvent tank 33 includes: solvent directly injected from solvent storage device 31 for soaking or heated fumigation treatment; solvent dripping under gravity after spraying by spray device 34; and condensed solvent vapors that condense and liquefy during fumigation, which also flow back to solvent tank 33. Therefore, in the actual operation cycle, the solvent in solvent tank 33 is a mixture of the above-mentioned liquid sources, serving as both the starting point of the process (supplying fumigation steam and soaking solution) and the endpoint of process liquid by-products (collecting spray drips, condensate, and soaking waste liquid).

[0039] Specifically, the solvent circulation system 30 includes a three-way valve 35. The solvent driving device 32 includes a first driving element 321, a second driving element 322, and a third driving element 323. The solvent storage device 31 is connected to the inlet of the three-way valve 35 via the first driving element 321, and is connected to the spray device 34 and the solvent tank 33 via the two outlets of the three-way valve 35, respectively. The second driving element 322 is disposed in the connecting pipe between the solvent tank 33 and the solvent filtration device 36, and is used to drive the solvent in the solvent tank 33 to be transported to the solvent filtration device 36. The third driving element 323 is disposed in the connecting pipe between the solvent filtration device 36 and the solvent storage device 31, and is used to drive the filtered solvent to be transported back to the solvent storage device 31.

[0040] The solvent storage device 31 is connected to the inlet of a three-way valve 35 via a first drive element 321. One outlet of the three-way valve 35 is connected to the spray device 34, and the other is connected to the solvent tank 33. Thus, by controlling the three-way valve 35, it is possible to determine whether the solvent flows to the spray device 34 or is directly injected into the solvent tank 33.

[0041] After the operation is completed, the recycling process is started. The waste liquid in solvent pool 33 is pumped into solvent filtration device 36 by second drive unit 322. Solid impurities are intercepted, and the clean solvent is pumped into solvent storage device 31 by third drive unit 323 for recycling and reuse.

[0042] The solvent filtration device 36 is used to treat complex contaminants in the circulating solvent, removing colloidal polymers, tiny solid particles, and other insoluble impurities generated by the dissolution and swelling of structural adhesives. Its purpose is to purify the solvent so that it meets the cleanliness requirements for reuse as a source liquid for spraying, soaking, or fumigation evaporation, thereby achieving economical and efficient closed-loop operation. Specifically, the solvent filtration device 36 can be one or more combinations of structures such as a cartridge filter, a centrifugal sedimentation machine, and an activated carbon adsorber; the present invention does not limit the specific type of the solvent filtration device 36.

[0043] Optionally, in this embodiment, since it is a loop, the solvent driving device 32 can use only one driving element to switch multiple valves to achieve supply and recovery. That is, valves are installed on each connecting pipeline, power is provided by the driving element, and the flow direction of the fluid is controlled by opening and closing the valves.

[0044] To improve the uniformity of solvent vapor within the chamber 10 during fumigation, the battery colloid dismantling equipment 100 also includes a convection device for circulating the gas within the chamber 10. The convection device includes a lower convection port 11 located at the lower part of the side wall of the chamber 10, an upper convection port 12 located at the upper part of the side wall of the chamber 10, a convection pipe connecting the lower convection port 11 and the upper convection port 12, and a fan installed on the convection pipe.

[0045] Understandably, the convection pipes are located on the outside of the housing 10. The fan is activated to draw out gas with a high solvent vapor concentration from the bottom of the housing 10 through the lower convection port 11, and then transport it through the convection pipes to the top of the housing 10, where it is blown in through the upper convection port 12. This creates gas circulation inside the housing 10, maintaining relatively uniform solvent vapor concentration, temperature, and humidity throughout the working chamber. This ensures that all battery packs, especially those on the upper fixed platform 22, receive consistent and efficient fumigation treatment, improving the consistency of disassembly quality.

[0046] Furthermore, the battery gel disassembly equipment 100 also includes a pressure monitoring device 13, an exhaust device 14, and a control unit. The pressure monitoring device 13 monitors the pressure inside the housing 10, and the exhaust device 14 is mounted on the housing 10. The control unit controls the exhaust device 14 to vent air from the housing 10 based on the pressure value monitored by the pressure monitoring device 13. Specifically, the pressure monitoring device 13 is a pressure sensor installed inside the housing 10 to monitor the internal pressure in real time. The exhaust device 14 is a solenoid exhaust valve installed on the top or side wall of the housing 10. The control unit is a PLC electrically connected to the pressure monitoring device 13 and the exhaust device 14.

[0047] During fumigation or spraying, solvent evaporation may cause the pressure inside the chamber to rise. The control unit continuously reads the signal from the pressure monitoring device 13. When the pressure value exceeds the preset safety threshold, the control unit immediately issues a command to open the exhaust device 14 to release the pressure. This improves the safety of the equipment and avoids safety accidents such as the chamber 10 bursting, the chamber 10 deforming, or even a large amount of solvent vapor leakage caused by excessive pressure, achieving safe operation under unattended or remote monitoring.

[0048] Furthermore, the battery gel disassembly equipment 100 includes a temperature control unit and a temperature monitoring device. The temperature monitoring device is used to monitor the solvent temperature in the solvent pool 33. The temperature control unit is used to control the solvent in the solvent pool 33 between 30°C and 40°C based on the temperature value from the temperature monitoring device. Specifically, the temperature monitoring unit is a temperature sensor that monitors the solvent temperature in the solvent pool 33. The temperature control unit continuously reads the signal from the temperature monitoring device. When the temperature value is lower than the preset threshold of 30°C, the temperature control unit immediately issues a command to control the heating device 40 to heat; when the temperature value reaches 30°C, the temperature control unit controls the heating device 40 to stop heating.

[0049] Understandably, precisely heating the temperature to and maintaining it within the low-temperature range of 30°C to 40°C is sufficient to promote the volatilization of most organic solvents during fumigation, meeting the vapor pressure required for the fumigation process. Immersion can appropriately accelerate the penetration and swelling reaction of the solvent into the structural adhesive, increasing the disassembly speed. This temperature is far below the critical temperature that could damage the internal chemical system of the battery cell (such as the SEI film, electrolyte, and electrode material structure); temperatures above 60°C are generally considered to significantly increase the risk. Therefore, while efficiently removing the adhesive, the health of the battery cell is protected to the greatest extent, ensuring it retains high reusability after disassembly.

[0050] In this embodiment, the enclosure 10 is a sealed enclosure 10, comprising a double-layer shell. An insulation layer is provided between the double-layer shell. Specifically, the insulation layer is made of materials such as rock wool or polyurethane foam. The sealed enclosure 10 ensures that solvent vapor does not leak during operation, guaranteeing a safe working environment and reducing solvent loss. The insulation layer between the double-layer shell effectively reduces heat loss from the interior of the enclosure 10 to the environment. This significantly reduces the energy consumption of the heating device 40 when maintaining a low-temperature fumigation temperature of 30-40℃.

[0051] This invention also provides a method for disassembling battery gel solvents applied to the above-described device embodiments, the method comprising: S1: Loading. Place the battery pack 201 to be processed onto the support platform 20.

[0052] S2: Mode Selection and Execution. Based on a preset program or real-time judgment, execute at least one of the following steps: Immersion treatment: Control the movement platform 21 to descend so that the battery pack 201 is at least partially immersed in the solvent in the solvent pool 33.

[0053] Fumigation treatment: The heating device 40 heats the solvent in the solvent pool 33 to generate solvent vapor, which is then used to fumigate the battery pack 201. This process is usually accompanied by the coordinated operation of the convection device, pressure monitoring device 13, and exhaust device 14.

[0054] Spraying treatment: The solvent driving device 32 is controlled to deliver the solvent to the spraying device 34, and the spraying device 34 sprays the battery pack 201.

[0055] S3: Solvent recovery. After the dismantling operation is completed, the solvent drive device 32 is controlled to transport the waste liquid in the solvent pool 33 to the solvent filtration device 36 for filtration and then recover it to the solvent storage device 31.

[0056] The beneficial effects of the battery colloid disassembly device 100 and disassembly method provided in this embodiment of the invention include: This invention allows the battery pack 201 to be immersed in the solvent pool 33 below the housing 10 for soaking treatment by placing the battery pack 201 on the support platform 20 and raising and lowering it via the movable platform 21. Alternatively, the solvent pool 33 below the housing 10 can be heated to generate solvent vapor for fumigating the battery pack 201. Or, the battery pack 201 can be sprayed with water by the spraying device 34. This invention can accommodate multiple degumming modes, cover the degumming needs of various structural adhesives for various battery packs, reduce the investment cost of degumming equipment, reduce the investment cost of solvents used in degumming, and the sealed structure of the housing 10 can reduce the amount of solvent evaporation during the process, thereby improving operational safety and environmental protection.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
