[0002] At present, there are two main methods for the safe discharge of waste lithium-ion batteries: one is physical discharge, which is mainly through external load dissipation, that is, the battery is connected to a resistor, and the power in the battery is consumed by heat release, but this method is only suitable for laboratory experiments, and large-scale discharge is not feasible; the other is chemical discharge, that is, using the positive and negative metals of the battery as the cathode and anode, and consuming the residual power in the battery through an electrolysis process in the solution. At present, sodium chloride solution is mainly used as the electrolyte and waste lithium-ion batteries are used as the power source for discharge. This method is simple and feasible, and is currently the main method for the discharge of waste lithium batteries.

[0003] Before the lithium battery is discharged, the battery needs to be stacked in a mesh frame, and then the pool is filled with brine. The mesh frame is lifted into the pool using a crane or other equipment, and the lithium battery in the mesh frame is immersed below the brine level in the pool. After a period of time, the discharge process of the waste lithium battery is completed. The crane is then used to lift the lithium battery in the pool together with the mesh frame, and the lithium battery is drained above the pool. The discharged lithium battery is then removed for the next crushing process. The next batch of waste lithium batteries will be placed in the original pool only after the discharged lithium batteries are removed. In this way, the brine immersion process of other lithium batteries will be delayed during the lithium battery draining process, making the current lithium battery recycling process inefficient.

DETAILED DESCRIPTION

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0028] like Figures 1 to 8 As shown, the present invention includes the following embodiments:

[0029] Embodiment 1: A lithium battery recycling device comprises a cell body 1 and a support leg 11 at the bottom of the cell body 1; the cell body 1 is filled with brine; the cell body 1 penetrates front and back and is rotatably sealed and connected to a main shaft 2; the outer wall of the main shaft 2 located on the inner side of the cell body 1 is fixedly connected to a main board 21; the main board 21 is in the shape of an elongated strip; the front side of the end of the main board 21 is eccentrically rotatably connected to a loading plate 3 through a secondary shaft 22; the outer wall of the loading plate 3 is fixedly connected to a loading bar 24; a plurality of the loading bars 24 extend toward the front side; a plurality of the loading bars 24 and the inner side of the loading plate 3 form a block-shaped loading area 25; the loading area 25 can enter the interior of the cell body 1 after the main shaft 2 rotates and is immersed in brine; the outer wall of the rear side of the cell body 1 is fixedly connected to a main motor 26; the output shaft of the main motor 26 is fixedly connected to the rear end of the main shaft 2.

[0030] In this embodiment, a groove 31 is provided at the lower rear side of the loading plate 3; a block 32 is slidably connected in the groove 31; the block 32 is connected to the bottom of the groove 31 via a first spring 33; a slot 27 is provided at the front side of the main board 21; the opening of the slot 27 is adapted to the opening of the slot 31; the slot 27 corresponds to the groove 31 after being at the upper limit position of the loading area 25; the end of the block 32 away from the first spring 33 can be inserted into the slot 27; the end of the block 32 inserted into the slot 27 is arranged in an arc shape.

[0031] Specifically, workers load the lithium batteries that need to be recycled into the loading frame, so that the lithium batteries in the loading frame are full. The loading frame is in a block shape and is adapted to the shape and specifications of the loading area 25. The inner and outer walls of the loading frame are connected, and the loading frame opening faces upward. When one loading area 25 is located directly above another loading area 25, the loading area 25 at the upper position is at the upper limit position, and the upper groove 31 is aligned with the corresponding card slot 27. The card block 32 at the upper position is inserted into the corresponding card slot 27 under the action of the corresponding first spring 33, so that the loading plate 3 at the upper position is locked with the main board 21, so that the loading plate 3 is not easy to shake, so that the loading area 25 is stable and convenient for subsequent loading of lithium batteries;

[0032] Since the opening of the loading area 25 is arranged toward the front side, the loading frame is moved into the loading area 25 at the upper position along the opening of the loading area 25 by a forklift or other tool to complete the loading process of the waste lithium battery. Then, the main motor 26 drives the main shaft 2 to rotate. During the rotation of the main shaft 2, the main board 21 is driven to rotate. The long main board 21 drives the secondary shaft 22 at the end to move around the main shaft 2. The two secondary shafts 22 drive the loading frames in their respective loading areas 25 to move. The loading frame at the upper position moves from top to bottom, and the loading frame at the lower position moves from bottom to top. Since the loading plate 3 is eccentrically connected to the secondary shaft 22 for rotation, the loading frame in the loading area 25 can move while keeping the opening facing upward. The groove 31 on the lower loading plate 3 is staggered with the corresponding card groove 27. The arc-shaped end of the lower card block 32 is retracted into the groove 31 to avoid the squeeze of the notch of the card groove 27, thereby releasing the lock between the lower loading plate 3 and the main board 21.

[0033] The loading area 25 that moves downward will drive the loading frame to rotate into the cell body 1 from top to bottom. The lithium batteries in the cell body 1 that have completed immersion and discharge will move from bottom to top with the loading frame. The lithium batteries that have completed immersion will move upward to the limit position with the loading frame. After the groove 31 on the rear side of the upward loading plate 3 is aligned with the corresponding card slot 27, the card block 32 is pushed by the corresponding first spring 33 to snap into the card slot 27, so that the upward loading plate 3 is locked with the main board 21. The lithium batteries in the upward loading frame begin to drain, and the lithium batteries in the downward loading frame begin to be immersed and discharged. Since the immersion and drainage of the lithium batteries are carried out simultaneously, the salt water in the cell body 1 will not be idle, thereby saving the recycling processing time of the lithium batteries and improving the recycling processing efficiency of the lithium batteries.

[0034] The loading frame moves upward to the limit position, so that the loading frame is not easy to shake after being locked, so that after the lithium batteries in the loading frame are drained, it is convenient for a forklift to take out the lithium batteries in the loading frame from the loading area 25, and load the next batch of lithium batteries, and repeat this process; because the end of the main board 21 is counterweighted by the corresponding loading frame, the counterweight at the end of the main board 21 is relatively balanced, so that the main board 21 is more stable when rotating with the main shaft 2;

[0035] In this embodiment, the main shaft 2 drives the loading area 25 at the end of the main board 21, so that the two loading areas 25 drive the corresponding loading frames to perform a swap cycle, so that the lithium batteries in one loading frame are drained while the lithium batteries in the other loading frame are immersed and discharged, so that the cell body 1 can be fully utilized to ensure the efficiency of lithium battery recycling and processing.

[0036] Embodiment 2: The pool body 1 is composed of a pool seat 12, a pool plate 13 and a movable plate 4; the pool seat 12 has a U-shaped cross-section; the support leg 11 is fixedly connected to the lower surface of the pool seat 12; the lower inner wall of the pool seat 12 is horizontally fixedly connected to the pool plate 13; the lateral end of the pool plate 13 is rotationally sealed and connected to the movable shaft 14; the movable shaft 14 passes through the pool seat 12 front and back and is rotationally sealed and connected to the pool seat 12; the movable plate 4 is fixedly connected to the outer wall of the movable shaft 14; the front and rear edges of the movable plate 4 are movably sealed with the inner wall of the pool seat 12; the rear side of the pool seat 12 is fixedly connected to the auxiliary motor 15; the output shaft of the auxiliary motor 15 is fixedly connected to the corresponding movable shaft 14; the liquid level in the pool body 1 decreases as the two movable plates 4 are opened; a water exchange pipe with a valve is provided on the front side of the pool seat 12; the water exchange pipe is flush with the upper surface of the pool plate 13 and is used for water exchange.

[0037] In this embodiment, the outer diameter of the movable shaft 14 is greater than the thickness of the pool plate 13 ; the lateral width of the pool plate 13 is adapted to the lateral width of the loading area 25 .

[0038] Before the main board 21 rotates, the two auxiliary motors 15 are controlled to rotate. The two auxiliary motors 15 will drive the corresponding movable shafts 14 to rotate. During the rotation of the movable shaft 14, the movable plate 4 will be driven to move inside the pool seat 12, and the two movable plates 4 will be controlled to move in the direction of moving away from each other, so that the upper ends of the two movable plates 4 are away from each other, so that the two movable plates 4 form an inverted eight-shaped shape, so that the salt water level in the pool body 1 will drop. Under the condition that the salt water does not overflow from the inside of the pool body 1, the salt water level is controlled to be as low as possible. After the two movable plates 4 are opened, the shielding of the loading frame is released, and then the main motor 26 will drive the main shaft 2 and the main board 21 to rotate. During the rotation of the main board 21, the loading frames in the two loading areas 25 will be driven to move. The lithium batteries in the loading frames that have completed immersion and discharge will move from bottom to top, so that the lithium batteries that have completed immersion will be removed from the salt water surface as the upper loading frame is moved out for drainage. The lithium batteries that have just been removed from the salt water surface will drain a large amount of salt water. By opening the two movable plates 4, the water receiving area is expanded to facilitate drainage and collection.

[0039] The lithium batteries to be soaked in the loading frame that has been loaded move from top to bottom and approach the pool plate 13. The lithium batteries to be soaked will enter the brine with a lower liquid level along with the loading frame. Since the liquid level of the brine is low, the liquid splashing degree formed after the loading frame contacts the brine liquid level is low, thereby reducing the liquid splashing as much as possible, making the surrounding working environment cleaner. As the lithium batteries to be soaked move down to the loading frame, the auxiliary motor 15 is controlled to drive the movable shaft 14 and the movable plate 4 to move in the opposite direction, and the upper ends of the two movable plates 4 will approach each other, so that the brine liquid level in the pool body 1 will rise, and the brine liquid level will gradually cover the lithium batteries to be soaked, thereby soaking the lithium batteries in the pool body 1. In addition, since the width of the pool plate 13 in the lateral direction is slightly larger than the width of the loading area 25 in the lateral direction, after the two movable plates 4 remain in a vertical state, the space formed between the two movable plates 4 is adapted to the volume of the loading frame, so that the brine in the pool body 1 is utilized as much as possible, avoiding the waste of the brine in the pool body 1, improving the utilization rate of the brine, and maximizing the lithium battery recovery efficiency.

[0040] Embodiment 3: An extension groove 41 is provided at one end of the movable plate 4 away from the movable shaft 14; the extension groove 41 penetrates the movable plate 4 in the front-to-back direction; an extension plate 42 is movably connected in the extension groove 41; the extension plate 42 is in movably sealing contact with the inner wall of the pool seat 12; the upper end of the extension plate 42 is connected to a roller 43; a strip groove 16 is horizontally provided on the rear inner wall of the pool seat 12; the two rollers 43 are movably connected in the corresponding strip grooves 16.

[0041] In this embodiment, the two rolling rods 43 are connected to the bag cloth 5; the bag cloth 5 removes impurities in the brine after the upper ends of the two movable plates 4 move away from each other; the lower end opening of the pool seat 12 is fixedly connected to the baffle 17; the baffle 17 is provided with a discharge pipe 18.

[0042] In this embodiment, the bag cloth 5 is in the shape of a conveyor belt; the movable plate 4, the pool plate 13 and the movable shaft 14 are all located on the inner side of the bag cloth 5; the upper end of the extension plate 42 is fixedly connected to the rotating sleeve 44; the roller 43 is rotatably connected in the rotating sleeve 44; one of the strip grooves 16 is provided with a first tooth 19 on the lower groove wall; one of the rollers 43 is provided with a second tooth 45 at the end; the second tooth 45 is meshed with the first tooth 19 for transmission; water flows through the bottom of the pool seat 12.

[0043] In this embodiment, the outer wall of the rolling rod 43 provided with the second teeth 45 is provided with sharp claws 46; the rolling rod 43 can drive the bag cloth 5 through the sharp claws 46; the outer walls of the two movable plates 4 are fixedly connected to the scraper strip 47; the scraper strip 47 intercepts impurities on the surface under the transmission of the bag cloth 5.

[0044] After the salt water inside the cell body 1 completes the immersion and discharge of the lithium batteries in the loading frame, and the loading area 25 above the cell body 1 is loaded with the loading frame, the auxiliary motors 15 rotate respectively and drive the corresponding movable shafts 14 to rotate, and the two movable shafts 14 will respectively drive the upper ends of the corresponding movable plates 4 to move away from each other, and the upper ends of the two movable plates 4 will drive the upper ends of their respective internal extension plates 42 to move away from each other during the process of moving away from each other, and the upper ends of the extension plates 42 are rotatably connected to the rollers 43 through the rotating sleeve 44, and one of the rollers 43 is provided with a second tooth 45 at the end, and the other roller 43 has no second tooth 45 at the end. The second teeth 45 are provided, so that when one of the rollers 43 moves along the corresponding strip groove 16, the meshing of the second teeth 45 and the first teeth 19 can drive the corresponding roller 43 to rotate. The end of the other roller 43 is not provided with the second teeth 45, so it can only move along the corresponding strip groove 16. During the rotation process, one of the rollers 43 will drive the sharp claws 46 on the outer wall to move the inner wall of the bag cloth 5, so as to fish the bag cloth 5 out of the salt water. As the upper ends of the two movable plates 4 move away from each other, the liquid level of the salt water will also drop, and the liquid surface area of ​​the salt water will also increase.

[0045] The bag cloth 5 is made of cloth material, so it can have good adhesion to the white floating objects. In this way, as the bag cloth 5 is taken out of the salt water, the white floating objects on the surface of the salt water will be taken out. The bag cloth 5 outside the salt water can pull the bag cloth 5 inside the salt water with gravity. The white floating objects pass over the rolling rod 43 and contact the scraper 47 with the transmission of the bag cloth 5. The scraper 47 can gather the white floating objects on the bag cloth 5 and then fall off in a concentrated manner. The fallen white floating objects fall into the bottom wall of the pool seat 12. Water flows through the bottom of the pool seat 12, and the water flow can The white floating objects and some impurities can be washed away to ensure the cleanliness of the bag cloth 5 outside the salt water. Then, after the two movable plates 4 move away from each other at the upper end, they will avoid the rotation of the main board 21. Then, the main board 21 will drive the loading frame at the end to rotate. When the two loading frames are moved to a horizontal position, the bag cloth 5 on the side where the two movable plates 4 move away from each other can pull the bag cloth 5 above the pool plate 13, so that the bag cloth 5 above the pool plate 13 is straightened. When the bag cloth 5 is straightened and exposed to the liquid surface, impurities can be fished out.

[0046] Workers can clean it according to their needs, or they can choose not to clean it, and just rely on the white floating objects to be taken out each time the bag cloth 5 is moved by the sharp claws 46; as the main board 21 continues to rotate, the loading frame will move closer to the pool plate 13, and the loading frame will press the bag cloth 5 into the salt water. Since one of the rollers 43 is provided with sharp claws 46, the bag cloth 5 close to the second teeth 45 cannot be transmitted, and the bag cloth 5 away from the second teeth 45 begins to enter the salt water. Due to the effect of the extension plate 42, the droplets formed after the loading frame enters the salt water are less likely to splash out; after the loading frame moves down to the extreme position, the upper ends of the two movable plates 4 approach each other under control, driving the roller 43 of the second teeth 45 to reverse and bring the cleaned bag cloth 5 into the inside of the salt water, and the excess bag cloth 5 in the salt water is pulled down and removed by the bag cloth 5 on the outside of the movable plate 4 without the restriction of the sharp claws 46, so that the corresponding lithium battery is immersed and discharged;

[0047] In this embodiment, the bag cloth 5 is transmitted during the process of the upper ends of the two movable plates 4 moving away from each other, so that the bag cloth 5 can bring out impurities floating on the surface of the salt water to the bottom of the pool seat 12, and then clean it under the flushing of the water flowing at the bottom of the pool seat 12, thereby purifying the salt water inside the pool body 1, ensuring the subsequent lithium battery immersion discharge effect, and improving the lithium battery recovery effect.
