Description

Technical Field

[0001] This invention belongs to the field of battery dismantling technology, specifically a refined and intelligent dismantling equipment for recycling waste lithium battery electrolyte. Background Technology

[0002] Waste lithium battery recycling is a crucial link in resource recycling. With the rapid development of new energy vehicles and energy storage industries, the amount of waste lithium batteries generated is increasing year by year. Efficiently recycling the valuable metals and materials in them has become an urgent problem for the industry. Currently, the main method for processing waste lithium batteries is pulverization, which involves crushing the entire battery to obtain mixed metal powder. However, this process has many shortcomings. First, the electrolyte evaporates when heated during pulverization, generating harmful gases that require a large amount of environmental protection equipment for treatment, increasing recycling costs. Second, the mixed powder contains metals such as aluminum, copper, and lithium, making separation difficult and resulting in low recycling value. Furthermore, the aluminum shell, once crushed and mixed with aluminum powder, cannot be recycled as a whole piece of aluminum, significantly reducing its economic value. Overall, the existing pulverization process cannot truly realize the full value of waste lithium batteries.

[0003] Publication No. CN218385378U discloses a dismantling device for waste lithium battery cells, including a frame. The frame is equipped with a movable clamping assembly and a fixed clamping assembly. The movable clamping assembly has a movable and rotatable first clamping member. The fixed clamping assembly is arranged facing the movable clamping assembly and has a second clamping member that cooperates with the first clamping member to clamp the lithium battery cell to be dismantled and rotates with the first clamping member. The rotation centers of the first and second clamping members are on the same straight line. Through the cooperation of the first clamping member on the movable clamping assembly and the second clamping member on the fixed clamping assembly, the lithium battery cell to be dismantled is clamped and rotated under the external force of a winding device, causing the lithium battery cell to be wound in the opposite direction. This achieves the automatic and rapid separation of the positive electrode, separator, and negative electrode of the lithium battery cell. This utility model has a simple structure, provides a firm and reliable clamping, and is applicable to the rapid clamping and dismantling of wound lithium battery cells of different sizes.

[0004] This device can separate the positive electrode, separator, and negative electrode in the battery cell, but it cannot completely remove and recycle the aluminum shell before disassembly, nor can it collect the electrolyte during disassembly. The electrolyte will still evaporate and cause pollution, and it does not have oxygen-free protection conditions. Residual charge during disassembly can easily cause fires. Therefore, a refined intelligent disassembly equipment for recycling waste lithium battery electrolyte is proposed. It can completely disassemble and recycle the aluminum shell, separate the separator and electrode without damage, and simultaneously recover the electrolyte. The entire process is closed under oxygen-free conditions, achieving zero emissions and zero pollution. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] This invention, through the coordinated arrangement of a first pusher plate, a second pusher plate, and a first conveyor seat, enables the device to identify the battery size via a camera, and then have the first and second pusher plates sequentially push the battery into the cutting station.

[0022] This invention, through the coordinated arrangement of a heater, a fan, and a first conveying pipe, enables the device to deliver hot nitrogen gas to the fifth transmission seat via an air conveyor frame, causing the residual electrolyte in the electrode to evaporate.

The condenser condenses the gaseous electrolyte into a liquid state and discharges it for recovery. The condensed nitrogen gas flows back to the fan via a second recovery pipe. The heater heats the returning nitrogen gas, which is then sent back to the air conveyor frame via the first conveying pipe for recycling. This invention solves the problem of environmental pollution and resource waste caused by the direct discharge of electrolyte in existing dismantling processes, ultimately achieving the effect of zero-emission electrolyte recovery.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1 to 7As shown, the disassembly mechanism 5 includes a first push plate 501, a second push plate 502, and a first conveyor seat 503. The first push plate 501 is installed at the top of the disassembly table 1, the second push plate 502 is located at the top of the disassembly table 1, the first conveyor seat 503 is located at the top of the disassembly table 1, and a second conveyor seat 504 is located at the top of the first conveyor seat 503.

The top of the disassembly table 1 is fixed with a second side slice 511, the top of the disassembly table 1 is equipped with a first transmission seat 512, the top of the disassembly table 1 is fixed with a top head 513, the top of the disassembly table 1 is fixed with a flip motor 514, the rotating end of the flip motor 514 is fixed with a disassembly chuck 515, the top of the disassembly table 1 is fixed with a flip frame 516, the top of the disassembly table 1 is equipped with a second transmission seat 517, the cutting head 505 can move vertically to adjust the cutting height according to the thickness of the lithium battery, the first side slice 509 can move horizontally, the second side slice 511 can move horizontally, and the first side slice 509 and the second side slice 511 cut the aluminum shell of the lithium battery from both sides respectively.

[0039] Using the above scheme: After the size of the lithium battery is identified by camera 4, the first push plate 501 pushes the lithium battery to the first conveyor seat 503, and the second push plate 502 pushes the lithium battery to the cutting station. The first conveyor seat 503 and the second conveyor seat 504 clamp the lithium battery from above and below and transport it forward. During the transport process, the cutting head 505 adjusts the cutting height vertically according to the thickness of the lithium battery to cut off the end of the lithium battery. After the end is cut off, the third push plate 506 and the reciprocating clamp 507 move the lithium battery step by step to the aluminum shell cutting station. The four push plates 508 press and fix the lithium battery. The first side slice 509 and the second side slice 511 move horizontally from both sides to cut the aluminum shell. The cutting head 505 cuts the top surface of the aluminum shell. After the three sides are cut, only the bottom thin skin of the aluminum shell is connected. The top head 513 moves forward and lifts up to flip the top surface of the aluminum shell. The flipping motor 514 drives the disassembly chuck 515 to clamp the aluminum shell and rotate it to the aluminum shell collection box. The flipping frame 516 cooperates with the flipping action. The second transmission seat 517 drives the disassembled core to continue to be transported to the separation table 2.

[0040] like Figures 1 to 11As shown, the separation mechanism 6 includes a support frame 601, a transmission clamp 602, and a first cutting blade 603. The support frame 601 is fixed to the top of the separation platform 2. The transmission clamp 602 is installed at one end of the support frame 601, and the first cutting blade 603 is installed at one end of the support frame 601. A third transmission seat 604 is installed at the top of the separation platform 2. A pressure cylinder 605 is provided at one end of the third transmission seat 604, and a take-up drum 606 is installed at the other end of the third transmission seat 604. A fourth transmission seat 607 is installed at the top of the separation platform 2. The top of the fourth transmission seat 607 is fixed with a second cutting blade 608. A separation seat 609 is installed at one end of the fourth transmission seat 607. A pressure head 610 is installed at the top of the fourth transmission seat 607. The first cutting blade 603 can cut the outer layer diaphragm of the core. When the winding drum 606 rotates, it can wind and pull away the cut upper layer diaphragm. Two sets of transmission clamps 602 are provided. The two sets of transmission clamps 602 are arranged opposite each other to clamp and feed the lower layer diaphragm. The pressure head 610 can move downward to poke open the lower layer diaphragm and separate the positive electrode sheet from the diaphragm.

[0041] Using the above scheme: Each component is supported and fixed by the support frame 601. After the core reaches the separation table 2, the first cutting blade 603 cuts the outer layer of the core membrane. The winding drum 606 rotates to wind and pull away the cut upper layer membrane. Two sets of transmission clamps 602 are set opposite to each other to clamp and transport the lower layer membrane towards the membrane outlet. The third transmission seat 604 drives the pressure cylinder 605 to press the core to prevent it from scattering. The fourth transmission seat 607 drives the second cutting blade 608 to cut the connection between the membrane and the electrode sheet. The separation seat 609 guides the positive and negative electrode sheets to be output in different directions. The pressure head 610 moves downward to poke open the lower layer membrane to separate the positive electrode sheet from the membrane. The positive electrode sheet is output from the top, and the negative electrode sheet is output from the bottom. The upper and lower layers of membrane are collected from two directions respectively.

[0042] like Figures 1 to 12As shown, the recycling mechanism 7 includes a heater 701, a fan 702, and a first conveying pipe 703. The heater 701 is fixed to the outside of the recycling platform 3. The fan 702 is installed at the input end of the heater 701. The first conveying pipe 703 is fixed to the output end of the heater 701. An air conveying frame 704 is fixed to the output end of the first conveying pipe 703. A fifth transmission seat 705 is installed inside the recycling platform 3. A recycling cover 706 is fixed to the top of the recycling platform 3. A first recycling pipe 707 is fixed to the output end of the recycling cover 706. A condenser 708 is fixed to the output end of the first recycling pipe 707. A second return valve is fixed to one end of the condenser 708. The output end of the second recovery pipe 709 is fixedly connected to the input end of the blower 702. The air conveyor frame 704 is located below the fifth transmission seat 705, and the recovery hood 706 is located above the fifth transmission seat 705. The air conveyor frame 704 conveys hot air to the top of the fifth transmission seat 705, and the recovery hood 706 draws away the vaporized electrolyte from the top of the fifth transmission seat 705. The condenser 708 is used to condense the vaporized electrolyte into a liquid state and discharge it. The condensed nitrogen gas flows back to the blower 702 through the second recovery pipe 709. The heater 701 is used to heat the returned nitrogen gas and then convey it to the air conveyor frame 704 through the first conveying pipe 703.

[0043] The above scheme is adopted as follows: Nitrogen gas is heated by heater 701, and blower 702 transports the hot nitrogen gas to air conveyor frame 704 through first conveying pipe 703. Air conveyor frame 704 is set below fifth transmission seat 705 and delivers hot air to the top of fifth transmission seat 705 to cause the residual electrolyte in the electrode to evaporate due to heat. Recovery hood 706 is set above fifth transmission seat 705 and draws away the vaporized electrolyte from the top of fifth transmission seat 705 under negative pressure. The vaporized electrolyte enters condenser 708 through first recovery pipe 707. Condenser 708 condenses the gaseous electrolyte in the pipe into liquid through cooling water circulation outside the pipe wall and discharges it from the bottom for recovery. The condensed nitrogen gas flows back to blower 702 through second recovery pipe 709. Heater 701 heats the returned nitrogen gas and then transports it to air conveyor frame 704 through first conveying pipe 703 for recycling, realizing closed-loop circulation of nitrogen gas and zero-emission recovery of electrolyte.

[0044] The working principle and usage process of this invention: After the waste lithium battery enters the dismantling table 1, the camera 4 takes a picture of the lithium battery to identify its size and dimensions. The dismantling table 1 is equipped with an oxygen detection device and a nitrogen replenishment device, which detects the oxygen content in the cavity in real time and replenishes nitrogen to ensure that the entire dismantling process is carried out under oxygen-free conditions. Each station is equipped with an independent protective cover, and each protective cover independently detects the oxygen content and replenishes nitrogen to prevent the residual charge of the lithium battery from contacting oxygen and causing a fire.

[0045] After identification, the first push plate 501 pushes the lithium battery to the first conveyor seat 503. The first conveyor seat 503 and the second conveyor seat 504 clamp the lithium battery from above and below and convey it forward. During the conveying process, the cutting head 505 adjusts the cutting height vertically according to the thickness of the lithium battery to cut off the end of the lithium battery. The end falls from the outlet and is collected. After the end is cut off, the internal core and aluminum shell of the lithium battery are exposed. The third push plate 506 and the reciprocating clamp 507 move the lithium battery step by step to the aluminum shell cutting station. The fourth push plate 508 presses and fixes the lithium battery on the plate, and the cutting head 505 cuts the top surface of the aluminum shell. The first side slice 509 and the second side slice 511 move horizontally from both sides to cut the side of the aluminum shell. After the aluminum shell is cut on three sides, only the bottom thin skin is connected. After the aluminum shell is opened, the plastic film inside the core and the core are exposed. The top head 513 moves forward and lifts up to open the top cover of the aluminum shell. The flipping motor 514 drives the disassembly chuck 515 to clamp the aluminum shell and rotate it to the aluminum shell collection box. The aluminum shell is recycled separately as a whole piece of aluminum. The flipping frame 516 cooperates with the flipping action. The plastic film is collected from the film outlet. The second transmission seat 517 drives the disassembled core to continue to be transported to the separation table 2.

[0046] During the conveying process, the core rolls may scatter. The position of each core roll is located by a vision positioning device. After the through-beam switch detects that the core rolls are in place, the clamping claws clamp the core rolls and convey them to the separation table 2. The two core rolls in a pair must be in the same direction. The flipping device flips one of the core rolls so that the disassembly directions of the two core rolls are consistent. In order to match the disassembly rhythm, the core roll sorting device distributes the core rolls to multiple disassembly channels in sequence.

[0047] After the core reaches the separation table 2, the first cutting blade 603 cuts the outer layer of the separator. The separator is a thin plastic film. The first cutting blade 603 is heated and lightly touches the separator to complete the cut, avoiding mechanical cutting that could damage the internal electrode. The winding drum 606 rotates to wind and pull away the cut upper separator. Two sets of transmission clamps 602 are set opposite each other to clamp and transport the lower separator towards the separator outlet. The third transmission seat 604 drives the pressure cylinder 605 to press the core to prevent it from scattering. After the upper separator is wound away, the positive electrode is exposed, while the lower separator still wraps the negative electrode. The fourth transmission seat 607 drives the second cutting blade 608 to cut the connection between the separator and the electrode. The pressure head 610 moves downward to pry open the lower separator. The separator is a soft material that bends downward and is collected from the separator outlet. The positive electrode is a hard material that is output from above the separation seat 609, and the negative electrode is output from below the separation seat 609. The positive and negative electrodes are output in long strips for subsequent electrolyte recovery.

[0048] After the positive and negative electrode plates enter the recovery platform 3, the fifth transmission seat 705 is a grid conveyor. The positive electrode plate passes above the grid conveyor and the negative electrode plate passes below it. The heater 701 heats the nitrogen gas. The fan 702 conveys the hot nitrogen gas through the first conveying pipe 703 to the air conveyor frame 704. The air conveyor frame 704 is located below the fifth transmission seat 705 and conveys the hot nitrogen gas above the fifth transmission seat 705. The hot nitrogen gas passes through the grid conveyor and heats the electrode plates. The residual electrolyte in the electrode plates evaporates due to the heat. The recovery hood 706 is located above the fifth transmission seat 705 and draws away the vaporized electrolyte from above under negative pressure. The intake and exhaust volumes of the hot nitrogen gas are kept synchronized to prevent outside air from entering the cavity. The vaporized electrolyte enters the condenser 708 through the first recovery pipe 707. The condenser 708 has a double-layer pipe structure inside. The inner pipe supplies the vaporized electrolyte, and the outer pipe supplies... After condensation, nitrogen is output. A cooling water circulation channel is provided on the outside of the pipe wall. The cooling water circulation keeps the pipe wall temperature at a low temperature. The gaseous electrolyte condenses into liquid inside the pipe and is discharged and recovered from the bottom. The condensed nitrogen flows back to the fan 702 through the second recovery pipe 709. The heater 701 heats the returned nitrogen and then transports it to the air conveyor frame 704 through the first conveying pipe 703 for recycling. The nitrogen is recycled in a closed-loop system, with only a small amount of nitrogen added to maintain the system pressure. After the electrode passes through the recovery platform 3, the residual electrolyte is removed. The output positive and negative electrode sheets are in a dry state and can directly enter the subsequent non-destructive de-powdering process. After the positive electrode sheet is de-powdered, the positive electrode material is collected, and after the negative electrode sheet is de-powdered, the negative electrode material is collected. The entire dismantling process is carried out in a fully enclosed oxygen-free environment. The electrolyte is recovered with zero discharge, the aluminum shell is recovered as a whole, the diaphragm and the electrode are separated without damage, and each component is collected independently to achieve resource utilization.
