Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of lithium battery recycling, and in particular to a pretreatment device for recycling waste lithium batteries. BACKGROUND

[0002] Lithium batteries are primary batteries using lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution, which are different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Lithium batteries contain cobalt, lithium, copper and plastic, which are all valuable resources and have high recycling value. Therefore, scientific and effective treatment of waste lithium batteries not only has significant environmental benefits, but also has good economic benefits. In order to alleviate the increasingly serious resource shortage and environmental pollution caused by rapid economic development, full-component recycling of waste lithium batteries has become a global consensus.

[0003] When lithium batteries are recycled, they usually need to be crushed and then screened to recover each component. However, before crushing, there is still residual electricity in the lithium battery, and direct crushing can easily cause self-ignition or explosion of the lithium battery. Therefore, the lithium battery needs to be discharged. The treatment method of the residual electricity of the lithium battery is mostly to immerse the lithium battery in an electrolyte, connect the positive and negative electrodes of the lithium battery, and thus achieve continuous discharge, but the speed is slow. Other ways are to perforate the lithium battery and then place it in the electrolyte to achieve the purpose of discharging. However, in actual application, there is a diaphragm between the positive and negative electrodes inside the lithium battery. The main function of the diaphragm is to prevent the positive and negative electrodes from contacting and allow ions to transfer through the diaphragm. Once the diaphragm is damaged by foreign matter puncture, if the foreign matter is a metal material, it will cause the positive and negative electrodes to short circuit through the metal foreign matter. If the foreign matter is a non-metal material, the diaphragm is damaged during the puncture process. Since the electrodes in the lithium ion battery are copper foil and aluminum foil, the copper foil and aluminum foil in the battery will be stuck on the needle after the needle is punctured, causing the lithium battery to fall off.

DETAILED DESCRIPTION

[0030] In order to make the above objectives, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0031] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0032] Secondly, the present application is described in detail in combination with the schematic diagram, in the detailed description of the embodiments of the present application, in order to facilitate the description, the cross-sectional view of the device structure will be partially enlarged without the general proportion, and the schematic diagram is only an example, which should not limit the scope of protection of the present application here. In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual manufacture.

[0033] Thirdly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an independent or alternative embodiment which is mutually exclusive with other embodiments.

[0034] Embodiment 1, refer to Figures 1-7The embodiment provides a pretreatment device for waste lithium battery recycling, which comprises a base 100, a mounting table 200, a feeding assembly 300 and a processing assembly 400.

[0035] The base 100 is provided with a guide portion 110.

[0036] The mounting table 200 is fixedly installed on the base 100 and comprises a mounting plate 210 and a sliding seat 220 fixed on the mounting plate 210 and used for conveying lithium batteries.

[0037] The feeding assembly 300 is fixedly installed on the sliding seat 220 and is responsible for feeding waste lithium batteries into the pretreatment device and comprises a refrigeration box 310 with a material port 311 at two ends and a shunt unit 320 installed in the refrigeration box 310, the shunt unit 320 divides the refrigeration box 310 into a plurality of storage spaces.

[0038] Preferably, the refrigeration box 310 can be designed to have a plurality of independent cooling zones, and each zone can be set to different temperatures as needed. This can be achieved by using multiple evaporators or installing baffles in a large cooling chamber, which can help control the flow of cold air to achieve different temperatures in different zones. The refrigeration box 310 is made of thermal insulation material to maintain stable internal temperature and prevent external temperature from affecting the temperature inside the box. The working principle is prior art and will not be repeated here.

[0039] In the pretreatment process of waste lithium batteries, one use scenario of the refrigeration box 310 is as follows:

[0040] 1. Battery adaptability test: Small-scale testing before large-scale freezing to determine the optimal freezing conditions;

[0041] 2. Preliminary cooling stage: Freeze waste lithium batteries in batches, set the initial temperature to 0-20℃, and monitor the battery temperature to ensure it is stable within the set temperature range;

[0042] 3. Final temperature stage: When the battery temperature is stable, gradually reduce the temperature to -40-60℃, continuously monitor the battery temperature, and adjust the cooling rate as needed;

[0043] 4. Temperature maintenance: Between each cooling stage, maintain the battery at the current temperature for a period of time to allow the battery sufficient time to adapt to the new temperature, reducing the likelihood of thermal runaway and lithium battery rupture.

[0044] The processing assembly 400 is fixedly installed on the mounting plate 210, and includes a cylinder 410, a horizontal rod 420 and a drilling part 430. The horizontal rod 420 is fixed to an output end of the cylinder 410. A guide frame 230 is fixedly installed on the sliding base 220. The drilling part 430 is slidingly installed in the guide frame 230 and is connected with the horizontal rod 420 through a threaded rod 440. When the cylinder 410 drives the horizontal rod 420 to descend, the drilling part 430 slides in the guide frame 230 and abuts against the lithium battery, so that the lithium battery is punctured to realize safe discharge.

[0045] With reference to Figure 6 Preferably, a threaded sleeve 450 is rotatably installed on the horizontal rod 420, and the threaded rod 440 is threadedly connected in the threaded sleeve 450.

[0046] The threaded rod 440 is fixedly connected with the drilling part 430, and the drilling part 430 is slidingly installed in the guide frame 230, so that the rotation degree of the threaded rod 440 is restricted. Therefore, the position of the threaded rod 440 in the threaded sleeve 450 can be changed by rotating the threaded sleeve 450, and the distance between the outer edge surface of the lithium battery and the drilling part 430 can be changed according to the diameter of the lithium battery of different models, so that the working performance of the drilling part 430 is effectively ensured.

[0047] The pre-processing device for recycling waste lithium batteries of the embodiment is used. The waste lithium batteries are put into the refrigeration box 310 through the feeding port 311. The temperature in the refrigeration box 310 is adjusted as required, so that the temperature of the waste lithium batteries is reduced, and the risk of thermal explosion in the discharge process is reduced. The refrigerated lithium batteries are conveyed below the drilling part 430. The cylinder 410 drives the horizontal rod 420 to move downward. The horizontal rod 420 drives the drilling part 430 to slide on the guide frame 230 through the threaded rod 440, so that the drilling part 430 contacts with the lithium battery and performs drilling operation. After drilling, the positive and negative electrodes in the lithium battery form a short circuit loop through the perforation, and forced discharge is started. The discharged lithium battery can be sent to a next processing unit.

[0048] Each structure will be described in detail below with reference to the drawings.

[0049] With reference to Figure 7 Specifically, the drilling part 430 includes a hollow shell 431 with an opening on one side, a connecting disc 432 and a drilling rod 433. The connecting disc 432 is located on the side of the hollow shell 431 close to the horizontal rod 420. The connecting disc 432 is connected with the hollow shell 431 through a movable part 434. The drilling rod 433 is rotatably connected with the connecting disc 432 and extends into the hollow shell 431. A motor 435 is fixedly installed on the connecting disc 432, and an output end of the motor 435 is connected with the drilling rod 433.

[0050] Preferably, the end of the drilling rod 433 used for drilling is an elongated needle made of non-metallic material such as ceramic or special plastic, which can penetrate the diaphragm and then immediately withdraw, achieving a quick and safe discharging process.

[0051] The hollow shell 431 is slidably installed with a first sliding block 436, which has a slope on one side close to the drilling rod 433, and the first sliding block 436 is fixedly connected with the first spring 437 between the inner wall of the hollow shell 431, and the movable end of the movable part 434 is installed with a roller 438 which is in abutment with the slope of the first sliding block 436.

[0052] Preferably, the movable part 434 includes a first sliding sleeve 401 fixedly installed on the hollow shell 431, and a first sliding rod 402 fixedly installed on the connecting disc 432, the first sliding rod 402 is in sliding connection with the first sliding sleeve 401, the part of the first sliding rod 402 located in the first sliding sleeve 401 has a flange 403, and the third spring 404 is movably installed on the first sliding rod 402, and the two ends of the third spring 404 are in abutment with the flange 403 and the inner bottom surface of the first sliding sleeve 401 respectively.

[0053] The guide frame 230 has a sliding groove 231, and the outer edge surface of the hollow shell 431 is fixedly installed with a second sliding block 439 matched with the sliding groove 231.

[0054] Through the above structure, when the air cylinder 410 drives the horizontal rod 420 to move downward, the hollow shell 431 follows the descent through the threaded rod 440, so that it is in contact with the lithium battery, and with the continuous downward pressure of the air cylinder 410, on the one hand, the connecting disc 432 exposes the drilling rod 433 from the hollow shell 431 through the movable part 434, and after the motor 435 is started, the output end drives the drilling rod 433 to rotate to realize the drilling and discharging operation on the waste lithium battery; on the other hand, when the drilling rod 433 moves downward, the roller 438 installed on the movable part 434 will be in contact with the slope of the first sliding block 436 and press the first sliding block 436 to slide along the inner bottom surface of the hollow shell 431 to the outside, until the drilling rod 433 finishes drilling and resets, the copper foil and aluminum foil in the battery will not be stuck on the drilling rod 433 under the action of the resetting force of the first sliding block 436, avoiding that the battery cannot be separated.

[0055] Referring to Figure 1 and Figure 2 , specifically, the sliding seat 220 is slidably installed with a push plate 460, the push plate 460 is slidably installed on the guide part 110, and the horizontal rod 420 and the push plate 460 are rotatably installed with a connecting arm 470.

[0056] Preferably, the push plate 460 is in contact with the bottom surface of the refrigeration box 310, achieving the plugging of the material port 311 below the refrigeration box 310.

[0057] Through the arrangement of the above structure, after the cylinder 410 starts, the output end drives the horizontal rod 420 to move downward, the horizontal rod 420 transmits the force to the push plate 460 through the connecting arm 470, the connecting arm 470 changes the direction of the force in a rotating manner, thereby converting the vertical movement of the horizontal rod 420 into the horizontal movement of the push plate 460, so that the push plate 460 is located outside the sliding seat 220 during the drilling process, and as the cylinder 410 resets, the connecting arm 470 drives the push plate 404 to move on the sliding seat 220, and pushes the frozen battery in the refrigeration box 310 to the lower side of the drilling part 430, so as to achieve the purpose of automatic feeding.

[0058] With reference to Figure 4 and Figure 5 Specifically, the shunting unit 320 includes a first shunting plate 321 and a second shunting plate 322, the first shunting plate 321 is fixedly installed with a connecting shaft 323, one end of the connecting shaft 323 away from the first shunting plate 321 penetrates out of the refrigeration box 310 and is fixedly installed with a ratchet wheel 324, the push plate 460 is provided with a tooth groove 461 matched with the ratchet wheel 324, the second shunting plate 322 is fixedly installed with a sleeve 325, the sleeve 325 is coaxially installed on the connecting shaft 323, the sleeve 325 and the connecting shaft 323 are both fixedly installed with a first bevel gear 326, and the refrigeration box 310 is internally rotatably installed with a second bevel gear 327, the second bevel gear 327 is in meshing connection with the first bevel gears 326 on the two sides.

[0059] Preferably, the first shunting plate 321 and the second shunting plate 322 are both provided with a storage groove 328 for placing the lithium battery.

[0060] It should be noted that the first shunting plate 321 and the second shunting plate 322 both include a fixed disc 301 and a rotating disc 302, the fixed disc 301 is fixedly installed in the refrigeration box 310 and has a gap for the battery to fall, and the rotating disc 302 is rotatably installed on the fixed disc 301 and is used to drive the battery to move to the gap.

[0061] Preferably, the refrigeration box 310 is internally fixedly installed with a baffle 330, and the baffle 330 and the first shunting plate 321 and the second shunting plate 322 are both provided with a space for accommodating the lithium battery.

[0062] The baffles 330 are symmetrically arranged, and the lithium battery passes between the two baffles 330.

[0063] Through the arrangement of the above structure, when the push plate 460 is pushed forward, the tooth groove 461 thereof will engage with the ratchet wheel 324 to drive the rotation of the connecting shaft 323. The rotation of the connecting shaft 323 in turn drives the rotation of the rotating disc of the first and second shunt plates 321 and 322. Since the first and second shunt plates 321 and 322 are provided with the storage grooves 328 and the rotating discs 302 thereof can rotate, when the rotating disc 302 rotates, the lithium battery will be pushed out from the gap on the fixed disc 301. At the same time, since the first and second bevel gears 326 and 327 are engaged, a coordinated action is formed to ensure that the lithium battery can move in a predetermined direction and order. Finally, the existence of the flow baffle 330 is to ensure that the lithium battery can pass in order and prevent the lithium battery from being mixed or blocked during the movement.

[0064] With reference to Figure 3 Specifically, the sliding seat 220 includes a fixed part 221 and a moving part 222, the second spring 223 is fixedly connected between the moving part 222 and the fixed part 221, the moving part 222 can move relative to the fixed part 221, the wedge-shaped block 224 is fixedly installed on the moving part 222, and the pusher 480 is fixedly installed on the horizontal rod 420 and has an inclined surface and can abut against the wedge-shaped block 224.

[0065] Preferably, the pusher 480 includes the second sliding sleeve 481 fixedly installed on the horizontal rod 420, and the second sliding rod 482 is slidingly installed in the second sliding sleeve 481 and is fixedly connected between one side in the second sliding sleeve 481 and the top surface in the second sliding sleeve 481.

[0066] Through the arrangement of the above structure, when the push plate 460 is pushed forward, the tooth groove 461 thereof will engage with the ratchet wheel 324 to drive the rotation of the connecting shaft 323. The rotation of the connecting shaft 323 in turn drives the rotation of the rotating disc of the first and second shunt plates 321 and 322. Since the first and second shunt plates 321 and 322 are provided with the storage grooves 328 and the rotating discs 302 thereof can rotate, when the rotating disc 302 rotates, the lithium battery will be pushed out from the gap on the fixed disc 301. At the same time, since the first and second bevel gears 326 and 327 are engaged, a coordinated action is formed to ensure that the lithium battery can move in a predetermined direction and order. Finally, the existence of the flow baffle 330 is to ensure that the lithium battery can pass in order and prevent the lithium battery from being mixed or blocked during the movement.

[0067] In summary, the working principle of the pretreatment device for recycling waste lithium batteries is as follows:

[0068] Firstly, the waste lithium batteries are put into the refrigeration box 310 through the material port 311 by manual or mechanical hand for stepwise freezing treatment, and the batteries are kept at the current temperature for a period of time between each temperature reduction stage, so that the batteries have enough time to adapt to the new temperature, and the possibility of thermal runaway and the rupture of the lithium batteries are reduced;

[0069] Then, the cylinder 410 is started, and its output end drives the horizontal rod 420 to move downward. The horizontal rod 420 transmits the force to the push plate 460 through the connecting arm 470, and the connecting arm 470 changes the direction of the force by rotating, thereby converting the vertical movement of the horizontal rod 420 into the horizontal movement of the push plate 460. The push plate 460 is moved on the sliding seat 220, and the frozen battery at the bottom of the refrigeration box 310 is pushed to the lower side of the guide frame 230.

[0070] Then, the motor 435 is started, and the drilling rod 433 is rotated to realize the drilling and discharging operation of the waste lithium battery. On the other hand, when the drilling rod 433 moves downward, the roller 438 installed on the movable part 434 will be in contact with the inclined surface of the first sliding block 436 and press the first sliding block 436 to slide outward along the inner bottom surface of the hollow shell 431. When the drilling rod 433 is reset after the drilling is completed, the copper foil and aluminum foil in the battery will not be stuck on the drilling rod 433 under the action of the resetting force of the first sliding block 436.

[0071] Finally, the cylinder 410 is reset, and its output end drives the horizontal rod 420 to move upward. The horizontal rod 420 transmits the force to the push plate 460 through the connecting arm 470. The tooth groove 461 on the push plate 460 is engaged with the ratchet wheel 324, so that the connecting shaft 323 will only rotate when the push plate 460 moves away from the cylinder 410. The rotation of the connecting shaft 323 drives the first bevel gear 326 to rotate, and the second bevel gear 327f engaged with the first bevel gear 326 also rotates, thereby driving the first bevel gear 326 on the other side to rotate. The first and second shunt plates 321 and 322 are coaxially and oppositely rotated, the baffle plate 330 flattens the lithium battery to realize orderly unloading, and prevents the lithium battery from being mixed or blocked during movement. When the cylinder 410 is started again, the push plate 460 can push the battery at the bottom of the refrigeration box 310 to the lower side of the guide frame 230 again, realizing continuous operation.
