Therefore, in order to protect the environment, lithium batteries need to be recycled.

[0003] Common lithium battery recycling requires discharge before recycling. The main discharge method currently used is sodium chloride solution immersion discharge. This method is simple in process and can also cool the battery. However, the main problem is that the heavy metals and fluorine that are inevitably produced during the discharge of lithium batteries in sodium chloride solution will contaminate the sodium chloride solution, and the discharged lithium batteries need to be collected in a centralized manner for washing with clean water, drying and other steps.

[0046] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0047] like Figure 1-8 As shown, the embodiment of the present disclosure discloses a discharge recovery device for waste lithium batteries, which includes:

[0048] The box body 100 is provided with a box door, which is mainly used for daily maintenance and replenishing water and salt for the liquid supply part 200 described below;

[0049] The liquid supply part 200 is arranged on the top of the box body 100, and the liquid supply part 200 includes a sodium chloride solution tank 220 and a clean water tank 230;

[0050] The cleaning frame 300 is used to hold the waste lithium battery. The sodium chloride solution tank 220 adds the sodium chloride solution into the cleaning frame 300. The clean water tank 230 can spray the clean water into the cleaning frame 300. The cleaning frame 300 is provided with a drain hole 320. Since the discharge of the waste lithium battery requires soaking and must be soaked for a sufficient time to complete the discharge, the method of directly adding the sodium chloride solution into the cleaning frame 300 is not only conducive to the discharge of the waste lithium battery, but also because the spraying method is bound to cause the solution to sputter, and a large amount of sodium chloride solution will cause a large amount of sputtering and cause a waste of resources, so adding the sodium chloride solution directly into the cleaning frame 300 can save the amount of sodium chloride solution; and the spraying method is also more conducive to the clean water to rinse off the sodium chloride solution on the waste lithium battery. It should be noted here that the drain hole 320 can be opened and closed by manual control;

[0051] The air drying section 400 includes an air source and a flat bag-shaped air drying bag 410 . The air drying bag 410 is provided with a plurality of air blowing holes 411 facing the cleaning frame 300 at intervals.

[0052] Through the above technical solution, the waste lithium battery is placed in the cleaning frame 300, the sodium chloride solution tank 220 is opened, and the sodium chloride solution is added to the cleaning frame 300. After soaking for a sufficient time and completing the discharge, the drain hole 320 is opened to discharge the waste sodium chloride solution from the drain hole 320. The clean water tank 230 is opened, and clean water is sprayed on the waste lithium battery to rinse the residual sodium chloride solution on the waste lithium battery. At this time, the drain hole 320 can be kept open all the time to speed up the flushing efficiency. After the flushing is completed, the wind source is turned on, and the wind source enters the air drying bag 410 and blows to the waste lithium battery through the blowing hole 411 on the air drying bag 410 to dry the waste lithium battery. The multiple steps of soaking discharge-clean water flushing-drying are all completed in the box 100 at one time, without the need for staff contact. The staff only needs to operate outside the box 100, which is automated and highly safe.

[0053] Optionally, a plurality of cleaning frames 300 may be arranged from bottom to top in the box body 100. Figure 1In the embodiment shown, two cleaning frames 300 are arranged in the box 100. A plurality of connecting holes can be arranged on the bottom plate of the cleaning frame 300, and a movable plate 330 capable of horizontal movement is arranged at the bottom of the cleaning frame 300. The movable plate 330 also has a plurality of connecting holes. The connecting holes on the bottom plate of the cleaning frame 300 can be completely exposed or completely closed by the movement of the movable plate 330. When the waste lithium battery is soaked and discharged, the connecting holes on the bottom plates of the two cleaning frames 300 are closed, and the respective drainage holes 320 are opened. The waste sodium chloride solution is still discharged through the respective drainage holes 320. However, when the waste lithium battery is rinsed, the connecting holes on the bottom plate of the cleaning frame 300 located above can be exposed, and the drainage holes 320 can be closed, and the connecting holes on the bottom plate of the cleaning frame 300 located below can be closed, and the drainage holes 320 can be opened. In this way, the waste lithium batteries in the two cleaning frames 300 can be cleaned by spraying clean water once, which can effectively save water resources and speed up the cleaning efficiency.

[0054] In some embodiments, the air drying unit 400 further includes a group of screws 450 which are arranged in parallel and whose two ends are respectively fixed to the two opposite inner walls of the box. A fixing ring 430 is provided on one side of the air drying bag 410. The fixing ring 430 is sleeved on the screw 450 and fixed thereto. A nut 440 which cooperates with the screw 450 is provided on the other side. The screw 450 is driven by a servo motor 460, and the air drying bag 410 can be unfolded or folded along the extension direction of the screw 450.

[0055] Through the above technical solution, when the air-drying bag 410 is not in use, the air-drying bag 410 can be folded up, which can reduce the space occupied on the one hand, and avoid the corrosion of the waste sodium chloride solution on the other hand. When there are multiple cleaning frames 300 in the box 100, multiple air-drying bags 410 can be set, and blowing holes 411 are opened on both sides of each air-drying bag 410, so that the adjacent upper and lower cleaning frames 300 can be air-dried at the same time.

[0056] exist Figure 1 In the embodiment shown, two air-drying bags 410 are provided, and the two air-drying bags 410 are simultaneously moved toward the middle until they are fully unfolded. Figure 2 In the illustrated embodiment, the air-drying bag 410 is provided with one, and the air-drying bag 410 is unfolded from one side to the other side. Both of the above-mentioned methods are acceptable and are not limited here.

[0057] Preferably, the air-drying bag 410 is made of a corrosion-resistant soft material, so that even if the discarded sodium chloride solution drips on the air-drying bag 410, it will not cause damage to the air-drying bag 410. As for the dripping of water, the water can also evaporate quickly with the wind blowing in, and will not affect the air-drying bag 410.

[0058] In some embodiments, at least one folding strip 420 is disposed on the air-drying bag 410 at intervals, and the air-drying bag 410 can be folded and stored along the folding strip 420. Through the above technical solution, the folding strip 420 is more conducive to the folding and storage of the air-drying bag 410.

[0059] In some embodiments, the cleaning frame 300 is provided with a liquid inlet 310 for communicating with the clean water tank 230, and a filter 360 is disposed in both the liquid inlet 310 and the drain hole 320, and a rotatable baffle 370 is disposed on one side of the filter 360 close to the outside of the cleaning frame 300;

[0060] Stoppers 380 are provided on the upper right side and the lower left side of the baffle 370 in the liquid inlet hole 310 so that the baffle 370 can only rotate counterclockwise.

[0061] Stoppers 380 are disposed at the upper left side and the lower right side of the baffle 370 in the drain hole 320 to enable the baffle 370 to rotate only clockwise.

[0062] Specifically, the filter 360 is to prevent the fragments of the waste lithium battery or some small waste lithium batteries such as button batteries from entering the pipeline through the liquid inlet 310 / drain hole 320. The baffle 370 in the liquid inlet 310 that can only rotate counterclockwise allows the sodium chloride solution to flow only from the right side of the baffle 370 to the left side, so that one-way flow can be achieved, and the impurities and waste solution remaining in the cleaning frame 300 will not enter the pipeline to pollute the clean sodium chloride solution. Similarly, when the waste lithium battery is rinsed with clean water, the part of the waste sodium chloride solution remaining in the drain hole 320 will not enter the cleaning frame 300 to pollute the cleaned waste lithium battery again.

[0063] In some embodiments, mutually attracting magnets are disposed on the stopper 380 and at positions of the baffle 370 corresponding to the stopper 380;

[0064] Two central shafts 371 are oppositely disposed on the baffle 370 . An elastic portion 372 is disposed at one end of the central shaft 371 away from the baffle 370 . The elastic portion 372 is cylindrical and has an outer diameter consistent with that of the central shaft 371 .

[0065] Through the above technical solution, the magnet can prevent the baffle 370 from rotating at will and prevent liquid leakage. The elastic part 372 can be made of rubber or other elastic materials. The central axis 371 and the elastic part 372 can be fixed on the baffle 370. A hole is punched on the hole wall of the liquid inlet hole 310 / the sewage hole 320 so that the elastic part 372 is fixed in the hole. In this way, the baffle 370 needs to overcome a certain elastic force from the elastic part 372 when rotating. After rotation, the baffle 370 can also return to its original position under the action of the elastic force of the elastic part 372 to close the liquid inlet hole 310 / the sewage hole 320.

[0066] In some embodiments, the discharge recovery device for waste lithium batteries further includes a flip assembly 500, which includes a flip motor 510, a rotating shaft 520 drivingly connected to the motor shaft of the flip motor 510, and a rotating wheel 530 drivingly connected to the rotating shaft 520, wherein an axis of the rotating wheel 530 and an axis of the rotating shaft 520 have an acute angle between them;

[0067] An annular rotating track 531 is opened on the outer periphery of the rotating wheel 530 along the circumference of the rotating wheel 530, and a support rod 570 is connected to the bottom / top of the cleaning frame 300. The end of the support rod 570 away from the cleaning frame 300 is slidably embedded in the rotating track 531. The support rod 570 can move up and down in the vertical direction as the rotating wheel 530 rotates.

[0068] By adopting the above technical solution, as the rotating wheel 530 rotates, the support rod 570 drives the two sides of the cleaning frame 300 to move up and down continuously, thereby turning over the waste lithium batteries in the cleaning frame 300, which is beneficial to the discharge, cleaning and air drying of the waste lithium batteries. When multiple cleaning frames 300 are provided, two cleaning frames 300 adjacent to each other can use the same rotating wheel 530, such as Figure 1 and Figure 2 As shown, a mounting plate 340 is provided on the top of the cleaning frame 300, one end of the support rod 570 of the cleaning frame 300 located below is connected to the cleaning frame 300 through the mounting plate 340, and the other end is embedded in the rotating track 531. As the rotating wheel 530 rotates, the upper and lower cleaning frames 300 shake up and down at the same time.

[0069] The up and down shaking cleaning frame 300 can flip the waste lithium batteries in the cleaning frame 300, so that the waste lithium batteries in the cleaning frame 300 can be cleaned more comprehensively during the cleaning stage, and the waste lithium batteries in the cleaning frame 300 can be dried more quickly and comprehensively during the air-drying stage.

[0070] In order to facilitate unloading, a collection door 350 is provided on the side of the cleaning frame 300, and a discharge frame 700 is provided on the outside of the box body 100. When unloading, the side of the cleaning frame 300 close to the discharge frame 700 is lowered, and the side of the cleaning frame 300 away from the discharge frame 700 is raised. In this way, after opening the box door and the collection door 350 of the box body 100, the used lithium batteries in the cleaning frame 300 can enter the discharge frame 700 more quickly to complete the unloading.

[0071] The collection door 350 can be opened manually or by means of an electric lifting rod. Since the cleaning frame 300 will shake and thus have a certain inclination, the length and / or width of the cleaning frame 300 is smaller than the length and / or width inside the box body 100.

[0072] In some embodiments, the flip assembly 500 further includes a fixing platform 560 fixed to the inner wall of the box 100, a fixing sleeve 540 passing through the fixing platform 560, and an adjusting bolt 550, the fixing sleeve 540 is adapted to the rotating shaft 520, a connecting key is provided between the fixing sleeve 540 and the rotating shaft 520, and the rotating wheel 530 is fixed to the end of the fixing sleeve 540;

[0073] The same side of the fixing sleeve 540 and the fixing platform 560 is provided with an edge plate for the adjusting bolt 550 to pass through. The fixing sleeve 540 can reciprocate along its axis in the fixing platform 560 and its position can be fixed by the adjusting bolt 550.

[0074] At least two rotating tracks 531 are arranged along the circumference of the rotating wheel 530 for the support rod 570 to change.

[0075] Through the above technical solution, when it is necessary to adjust the up and down movement range of the cleaning frame 300, it can be changed by changing the rotating track 531. Figure 7 and Figure 8 In the example embodiment, three rotating rails 531 are provided, and a turning rail 532 is provided between the three rotating rails 531. Before changing the rotating rail 531, it is necessary to transfer the end of the support rod 570 to the turning rail 532, move the position of the fixed sleeve 540 in the fixed platform 560, move the end of the support rod 570 from the position in the turning rail 532, and stop when the end of the support rod 570 is located at the intersection of the turning rail 532 and the rotating rail 531, so that the end of the support rod 570 can smoothly enter the rotating rail 531.

[0076] Preferably, two clamping plates 541 are further provided at the fixing sleeve 540, one of which is fixed to the bottom of the edge plate of the fixing sleeve 540, and the other is a movable clamping plate 541, and the two clamping plates 541 clamp the edge plate of the fixing sleeve 540 therebetween, and the adjusting bolt 550 passes through the clamping plates 541. The clamping plates 541 can improve the stability of the fixing of the fixing sleeve 540 by the adjusting bolt 550.

[0077] In some embodiments, a protective shell 600 capable of containing all components of the flip assembly 500 located in the box 100 is disposed inside the box 100, wherein one end of the support rod 570 can extend out of the protective shell 600;

[0078] A fixing plate 571 is provided on the support rod 570 and a support spring 580 is sleeved on the support rod 570 . One end of the support spring 580 abuts against the fixing plate 571 , and the other end abuts against the inner wall of the protective shell 600 . The support spring 580 is in a compressed state.

[0079] Through the above technical solution, the support spring 580 has a certain shock-absorbing and buffering function, so that the up and down movement of the cleaning frame 300 is more stable.

[0080] In some embodiments, an infusion tube 280 is disposed between the sodium chloride solution tank 220 and the liquid inlet 310 , and the infusion tube 280 is made of a flexible material.

[0081] Since the cleaning frame 300 needs to move up and down, the infusion tube 280 needs to have a certain flexibility, so that a good liquid supply / drainage effect can be maintained during the up and down movement of the cleaning frame 300.

[0082] In some embodiments, the liquid supply unit 200 further includes a water storage tank 210, a water delivery pipe 211 connected to the water storage tank 210 at one end, and a control valve 240 connected to the other end of the water delivery pipe 211;
