Technical Field
[0001] This utility model belongs to the field of lithium battery puncture discharge technology, and in particular relates to a lithium battery recycling puncture discharge device. Background Technology
[0002] With the rapid development of new energy vehicles and electronic products, the production and consumption of lithium batteries are constantly increasing, and the number of waste lithium batteries is also growing rapidly, driving the rapid development of the lithium battery recycling industry. Currently, numerous lithium battery recycling companies have emerged globally, recycling technology is constantly improving, and the scale of recycling is gradually expanding. In the lithium battery recycling process, lithium battery discharge is a crucial step, aiming to safely and effectively release the charge within the battery and reduce safety risks during subsequent processing.
[0003] When discharging lithium batteries, puncture discharge is commonly used. A sharp object (such as a steel needle) is used to puncture the lithium battery, causing a short circuit between the positive and negative electrodes inside the battery, thereby quickly releasing the charge inside the battery. However, during the puncture process, lithium batteries are prone to overheating, fire, or even explosion, posing significant safety hazards. Utility Model Content
[0004] To address the aforementioned problems, this invention proposes a lithium battery recycling puncture discharge device to more accurately resolve the problems described above.
[0005] This utility model is achieved through the following technical solution:
[0006] This utility model proposes a lithium battery recycling puncture discharge device, including a base plate, a support rod fixedly connected to the upper surface of the base plate, a support plate fixedly connected to the upper end of the support rod, a square through groove provided on the support plate, a placement box fixedly connected in the square through groove, a placement plate provided in the placement box, a puncture component provided above the placement plate, a first conveying pipe and a second conveying pipe respectively provided on the upper surface of the support plate on both sides of the placement box, the first conveying pipe being used to convey cooling water, and the second conveying pipe being used to convey sand.
[0007] In one example, the lower surface of the placement box is open, and a vertical plate is fixedly connected to the lower surface of the placement box, with a support plate rotatably connected between the vertical plates.
[0008] In one example, two fixed plates are fixedly connected to the upper surface of the support plate, and sliding seats are slidably connected to each fixed plate. Vertical rods are fixedly connected to one side of each sliding seat, and the vertical rods are fixedly connected to the placement plate. An installation plate is fixedly connected between the two vertical rods.
[0009] In one example, the puncture assembly includes a hydraulic cylinder fixedly connected to a mounting plate. The telescopic rod of the hydraulic cylinder is fixedly connected to a horizontal plate. A puncture needle is fixedly connected to the lower surface of the horizontal plate. A sliding rod is slidably connected to the horizontal plate, passing through the horizontal plate. A limiting block is fixedly connected to the upper end of the sliding rod. A spring is fixedly connected between the limiting block and the horizontal plate. The lower ends of the two sliding rods are fixedly connected to fixing rings, the height of which is lower than that of the puncture needle.
[0010] In one example, the first and second conveying pipes are respectively fixedly connected to two fixed plates. Both the first and second conveying pipes face the placement box. The upper ends of both the first and second conveying pipes are fixedly connected to the storage box. Both the first and second conveying pipes are equipped with solenoid valves.
[0011] In one example, a first rack is slidably connected to the support plate, a support rod is fixedly connected to one side of the first rack, the support rod is located below the support plate, a support frame is fixedly connected between the two sliding seats, a second rack is fixedly connected to one side of the support frame, a servo motor is installed on one side of one of the fixed plates, a rotating rod is fixedly connected to the main shaft of the servo motor, a gear is fixedly connected to the outside of the rotating rod, and the gear meshes with the first rack and the second rack.
[0012] The lithium battery recycling puncture discharge device proposed in this utility model can bring the following beneficial effects:
[0013] Firstly, by setting up a placement box, a first conveying pipe, and a second conveying pipe, the waste lithium batteries are placed on a placement plate, which is located inside the placement box. During the puncture process, if the lithium battery catches fire, sand is conveyed into the placement box through the second conveying pipe to bury the lithium battery, isolate oxygen, and play a role in extinguishing the fire. At the same time, cooling water is conveyed into the placement box through the first conveying pipe to cool down the lithium battery in the sand. The placement box provides shelter to prevent flames from shooting out, and the sand covering also provides a buffering effect when the lithium battery explodes.
[0014] Secondly, by setting a fixing ring, the hydraulic cylinder pushes the puncture needle down. The fixing ring contacts the lithium battery first. As the puncture needle descends to puncture the lithium battery, the sliding rod slides on the horizontal plate and the spring is compressed. When the puncture is completed and the puncture needle rises, the fixing ring continues to squeeze the lithium battery under the action of the spring, pushing the lithium battery downward, thus preventing the puncture needle from getting stuck on the lithium battery and being difficult to separate.

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.
[0023] like Figures 1-4 As shown in the figure, an embodiment of this utility model proposes a lithium battery recycling puncture discharge device, including a base plate 1, a support rod 2 fixedly connected to the upper surface of the base plate 1, a support plate 3 fixedly connected to the upper end of the support rod 2, a square through groove on the support plate 3, a placement box 4 fixedly connected in the square through groove, a placement plate 5 disposed in the placement box 4, waste lithium batteries are placed on the placement plate 5, the placement plate 5 is located in the placement box 4, a puncture component 6 is disposed above the placement plate 5, the puncture component 6 punctures and discharges the lithium batteries, and the upper surface of the support plate 3 is located in the placement box 4. A first conveying pipe 7 and a second conveying pipe 8 are respectively provided on both sides. The first conveying pipe 7 is used to convey cooling water, and the second conveying pipe 8 is used to convey sand. During the puncture process, when the lithium battery catches fire, sand is conveyed into the placement box 4 through the second conveying pipe 8 to bury the lithium battery, isolate oxygen, and play a role in extinguishing the fire. At the same time, the first conveying pipe 7 conveys cooling water into the placement box 4 to cool down the lithium battery in the sand. The placement box 4 provides shelter to prevent flames from shooting out. At the same time, the sand covering provides a buffering effect when the lithium battery explodes.
[0024] like Figure 4As shown, the lower surface of the placement box 4 is open, and the lower surface of the placement box 4 is fixedly connected to the vertical plate 9. The vertical plate 9 is rotatably connected to the support plate 10. When puncturing, the support plate 10 is horizontal and blocks the placement box 4, allowing sand to accumulate in the placement box 4 and cover the lithium battery. After the lithium battery is punctured and discharged, the support plate 10 rotates downward and opens the space under the placement plate 5. At this time, the second conveying pipe 8 is closed, and the cooling water in the first conveying pipe 7 is continuously conveyed. The impact sand slides out of the placement box 4 from the inclined support plate 10, which facilitates the recovery of the sand. After the sand flows out, it is convenient to remove the discharged lithium battery.
[0025] like Figure 2 and Figure 4 As shown, two fixed plates 11 are fixedly connected to the upper surface of the support plate 3. Sliding seats 12 are slidably connected to each fixed plate 11. Vertical rods 13 are fixedly connected to one side of each of the two sliding seats 12. The vertical rods 13 are fixedly connected to the placement plate 5. An installation plate 14 is fixedly connected between the two vertical rods 13. By setting the sliding seats 12, the height of the placement plate 5 can be adjusted. Before puncture, the placement plate 5 is higher than the placement box 4, which makes it easier to place the lithium battery on the placement plate 5. After that, the placement plate 5 enters the placement box 4 for puncture, which is more convenient.
[0026] like Figure 2 and Figure 4 As shown, the puncture assembly 6 includes a hydraulic cylinder 61, which is fixedly connected to the mounting plate 14. The telescopic rod of the hydraulic cylinder 61 is fixedly connected to a horizontal plate 62. A puncture needle 63 is fixedly connected to the lower surface of the horizontal plate 62. A sliding rod 64 is slidably connected to the horizontal plate 62, passing through the horizontal plate 62. A limiting block is fixedly connected to the upper end of the sliding rod 64. A spring 65 is fixedly connected between the limiting block and the horizontal plate 62. A fixing ring 66 is fixedly connected to the lower ends of the two sliding rods 64. The height of the fixing ring 66 is lower than that of the puncture needle 63. When puncturing, the hydraulic cylinder 61 pushes the puncture needle 63 down. The fixing ring 66 contacts the lithium battery first. As the puncture needle 63 descends to puncture the lithium battery, the sliding rod 64 slides on the horizontal plate 62, and the spring 65 is compressed. When the puncture is completed and the puncture needle 63 rises, the fixing ring 66 continues to squeeze the lithium battery under the action of the spring 65, pushing the lithium battery downward to prevent the puncture needle 63 from getting stuck on the lithium battery and being difficult to separate.
[0027] like Figure 1 and Figure 2As shown, the first conveying pipe 7 and the second conveying pipe 8 are fixedly connected to two fixed plates 11 respectively. Both the first conveying pipe 7 and the second conveying pipe 8 face the placement box 4. The upper ends of the first conveying pipe 7 and the second conveying pipe 8 are fixedly connected to storage boxes 15. Solenoid valves are installed on the first conveying pipe 7 and the second conveying pipe 8. One of the two storage boxes 15 stores cooling water and the other stores sand, which are used for covering and cooling in case of fire. The first conveying pipe 7 and the second conveying pipe 8 are controlled by solenoid valves, and personnel can stay away to avoid injury.
[0028] like Figure 3 and Figure 4 As shown, a first rack 16 is slidably connected to the support plate 3. A support rod 17 is fixedly connected to one side of the first rack 16. The support rod 17 is located below the pallet 10. A support frame 18 is fixedly connected between the two sliding seats 12. A second rack 19 is fixedly connected to one side of the support frame 18. A servo motor is installed on one side of one of the fixed plates 11. The main shaft of the servo motor is fixedly connected to a rotating rod 20. A gear 21 is fixedly connected to the outside of the rotating rod 20. The gear 21 meshes with the first rack 16 and the second rack 19. When the lithium battery is placed on the placement plate 5, the operator moves away, the servo motor starts, and drives the first rack 16 and the second rack 19 to slide, causing the placement plate 5 to descend into the placement box 4. The support rod 17 rises, pushing the pallet 10 to horizontally close the placement box 4. After puncture, the servo motor reverses, the placement plate 5 drives the lithium battery to rise and leave the placement box 4, the support rod 17 descends, the pallet 10 tilts, and the sand in the placement box 4 flows out for unloading. The operation is simple and convenient.
[0029] Working principle: After the lithium battery is placed on the placement plate 5, and the operator moves away, the servo motor starts, causing the first rack 16 and the second rack 19 to slide, making the placement plate 5 descend into the placement box 4. The support rod 17 rises, pushing the tray 10 to horizontally close the placement box 4. When the lithium battery catches fire, sand is transported into the placement box 4 through the second delivery pipe 8 to bury the lithium battery, isolate oxygen, and play a role in extinguishing the fire. At the same time, cooling water is transported into the placement box 4 through the first delivery pipe 7 to cool the lithium battery in the sand. After puncture, the servo motor reverses, the placement plate 5 drives the lithium battery to rise and leave the placement box 4, the support rod 17 descends, the tray 10 tilts, and the sand in the placement box 4 flows out.
