Technical Field
[0001] The utility model relates to the field of lithium battery recycling and discharging, in particular to a lithium battery recycling and discharging device. Background Art
[0002] In recent years, with the wide application of lithium-ion batteries, a large number of waste lithium batteries have been generated. When batch-processing waste lithium batteries, in the discharging process, due to short circuits, crushing, etc. during the decomposition process, the remaining power of the battery will be rapidly released, causing overheating and even explosion. Therefore, waste lithium-ion batteries must be fully discharged before recycling. Currently, there are mainly two methods for the safe discharging of waste lithium-ion batteries: one is physical discharging, mainly by discharging electricity through an external load, that is, connecting the battery to a resistor, and the power in the battery is consumed by heat release, but this method is only applicable to laboratory tests and large-scale discharging is not feasible; the other is chemical discharging, that is, using the positive and negative electrode metals of the battery as the cathode and anode, and consuming the remaining power in the battery through the electrolysis process in the solution. When discharging in brine, the batteries are generally directly stacked in a hanging basket, and the random placement of lithium batteries is likely to cause contact between the positive and negative electrodes of the lithium battery, thus posing a risk of normal short-circuit explosion. Then, the hanging basket is placed in the brine battery for discharging. After discharging, the hanging basket is lifted from the brine battery, and the batteries in the hanging basket are drained. However, in the draining process, it is found that since the brine flows through the stacked batteries from top to bottom in sequence, the batteries at the bottom of the hanging basket are difficult to drain. In order to ensure that the batteries in the hanging basket can be fully drained, a longer draining time is required. To solve the above problems, we propose a lithium battery recycling and discharging device. Content of the Utility Model

The output end of the motor 10 is fixedly connected to a second gear 11. The second gear 11 meshes with the first gear 4.
[0021] Specifically, through the meshing of the first gear 4 and the second gear 11, and then through the rotation of the universal joint 5, the hollow column 3 can be conveniently rotated.
[0022] In this embodiment, four sets of clamping plates 14 are fixedly connected to the outer side of the hollow column 3. A base 16 is arranged at the lower end of the hollow column 3. The lower end of the base 16 is fixedly connected to the battery 1. A clamping groove 15 is formed inside the base 16, and the clamping plate 14 is adapted to the clamping groove 15.
[0023] Specifically, by clamping the clamping plate 14 in the clamping groove 15, the hollow column 3 can always be kept in a standing state, which is convenient for the hoisting mechanism to hoist the device.
[0024] In this embodiment, an air inlet pipe 7 is fixedly connected to the outer side of the fixed column 6. A hot air blower 8 is fixedly connected to the front end of the air inlet pipe 7. The hot air blower 8 is fixedly connected to the connection box 12.
[0025] Specifically, through the intercommunication between the fixed column 6 and the air inlet pipe 7, the hot air blown out by the hot air blower 8 can conveniently enter the hollow column 3.
[0026] In this embodiment, a plurality of drain holes are formed in the outer side of the placement box 2. An exhaust pipe 21 is arranged inside the placement box 2. The exhaust pipe 21 is communicated with the hollow column 3. A plurality of exhaust holes are formed in the outer side of the exhaust pipe 21.

[0030] It should be noted that the present utility model is a lithium battery recycling and discharging device. The user fills the battery 1 with brine through the water inlet pipe 17. At this time, by rotating the handle 23, the rotation of the handle 23 drives the screw rod 22 to rotate. Then, through the cooperation of the hinge 25, the box door 26 can be opened. At this time, the lithium batteries are sequentially placed into the placement box 2. Through the cooperation of the screw rod 22 and the screw hole 24, the box door 26 can be closed. Then, the hoisting mechanism hoists the device through the lifting ring 13. Then, through the cooperation of the clamping plate 14 and the clamping groove 15, the device can be immersed in the brine. When the lithium battery finishes discharging, the device is hoisted through the lifting ring 13 again. At this time, the motor 10 is started. The output end of the motor 10 drives the second gear 11 to rotate. The rotation of the second gear 11 drives the first gear 4 to rotate. Then, through the universal joint 5, the device can be rotated. At this time, the brine in the placement box 2 can be thrown out by centrifugal force. At this time, by starting the hot air blower 8, the hot air blown out by the hot air blower 8 enters the inside of the hollow column 3 through the inside of the fixed column 6 and the universal joint 5. Then, the lithium battery is quickly dried through the exhaust holes on the outer side of the exhaust pipe 21. After being soaked for a long time, the brine in the battery 1 will become turbid due to impurities. At this time, the brine can be discharged through the drain pipe 18, so that the brine can be replaced.
