Description

Vehicle-mounted battery recycling equipment Technical Field

[0001] The present disclosure relates to the technical field of vehicle-mounted waste battery recycling equipment, and in particular to a vehicle-mounted battery recycling equipment. Background Art

[0002] Live battery crushing involves crushing used batteries while they are still undischarged, allowing for the recycling of useful materials. This method results in a mixture of various flakes within the crushed material, necessitating multiple sorting steps, including flotation and magnetic separation, to separate the electrode fragments. Chemical leaching is then used to recover the battery materials and current collectors. This results in significant material loss, a low recovery rate, and increased separation difficulty.

[0003] In order to solve the problems of low battery material recovery rate and greater difficulty in separation, the battery recycling method adopts the steps of first removing the core by shelling and then separating and recycling the core, such as CN202211615646.1. Although this can solve the problems of low battery material recovery rate and greater difficulty in separation, it requires discharging first and then shelling and removing the battery cell for processing, which makes the battery recycling efficiency low.

[0004] Summary of the Invention

[0005] Based on this, it is necessary to provide an on-board battery recycling device that can not only solve the problem of low battery material recovery rate and greater separation difficulty in battery charged crushing, but also solve the problem of low battery recycling efficiency in shelling, separation and crushing.

[0006] A vehicle-mounted battery recycling device comprises a base, a suspension and transport mechanism, a loading mechanism, a liquid cooling mechanism and a positioning and transport mechanism sequentially arranged along the suspension and transport mechanism;

[0007] The loading mechanism is arranged on the base, and is used to transport the battery positioning plate to a first predetermined position; the battery positioning plate is provided with a plurality of positioning grooves for positioning the batteries;

[0008] The liquid cooling mechanism includes a liquid cooling drive and a first sliding door. The base is provided with a refrigerated liquid nitrogen storage tank and a first slide groove. The refrigerated liquid nitrogen storage tank is connected to the first slide groove. The liquid cooling drive is installed on the base. The first sliding door is located in the first slide groove and is slidably connected to the base. The power output end of the liquid cooling drive is connected to the first sliding door to drive the first sliding door to open or close the refrigerated liquid nitrogen storage tank.

[0009] The suspension and transportation mechanism is located above the base, and is used to loosen or clamp the battery positioning tray so as to sequentially transport the battery positioning tray from the loading mechanism to the frozen liquid nitrogen storage tank and the positioning and transportation mechanism;

[0010] The positioning and conveying mechanism is installed on the base, and the positioning and conveying mechanism is used to position and convey the battery positioning tray; the vehicle-mounted battery recycling equipment also includes a shelling mechanism and a core removal mechanism arranged in sequence along the conveying direction of the positioning and conveying mechanism, the shelling mechanism is used to shell the batteries on the battery positioning tray, and the core removal mechanism is used to remove the battery core of the battery positioning tray after shelling.

[0011] Compared with the related art, the present disclosure has the following advantages including but not limited to:

[0012] 1. The above-mentioned vehicle-mounted battery recycling equipment loads multiple batteries through a battery positioning tray. When the battery positioning tray loaded with batteries is transported to a first predetermined position by a loading mechanism, a liquid-cooled drive member drives a first sliding door to open a frozen liquid nitrogen storage tank. The suspension transport mechanism first clamps the battery positioning tray from the loading mechanism and transports it to the frozen liquid nitrogen storage tank for freezing. The frozen battery positioning tray is then transported from the frozen liquid nitrogen storage tank to the positioning and transporting mechanism. The positioning and transporting mechanism then transports the battery positioning tray in sequence to positions corresponding to the shelling mechanism and the coring mechanism, respectively. The multiple batteries on the battery positioning tray are first subjected to a batch shelling operation by the shelling mechanism, and then the cores are removed in batches by the coring mechanism, thereby realizing batch battery recycling.

[0013] 2. Because the batteries are frozen before being shelled, the battery temperature is lower when the shells are removed, which reduces the risk of the batteries catching fire due to excessively high temperatures during shelling. Compared with the traditional method of discharging first and then shelling and removing the battery cells, the efficiency of battery recycling is improved, and the problem of low battery material recovery rate and greater separation difficulty caused by charged battery crushing is avoided.

The term "and / or" used herein includes any and all combinations of one or more of the relevant listed items.

[0019] As shown in Figures 1 to 4, an on-vehicle battery recycling device 10 according to one embodiment includes a base 100, a suspension transport mechanism 200, a loading mechanism 300, a liquid cooling mechanism 400, and a positioning and conveying mechanism 500, which are sequentially arranged along the suspension transport mechanism 200. The loading mechanism 300 is mounted on the base 100 and is used to transport a battery positioning tray 20 to a first predetermined position. The battery positioning tray 20 has multiple positioning slots 22 for positioning batteries 30. This allows the tray 20 to simultaneously position and load multiple batteries, allowing for simultaneous cooling, shelling, and cell extraction, thereby improving battery recycling efficiency.

[0020] In one embodiment, the liquid cooling mechanism 400 includes a liquid cooling drive 410 and a first sliding door 420. The base 100 is provided with a frozen liquid nitrogen storage tank 102 and a first slide 104. The frozen liquid nitrogen storage tank 102 is connected to the first slide 104. The liquid cooling drive 410 is mounted on the base 100. The first sliding door 420 is located in the first slide 104 and is slidably connected to the base 100. The power output end of the liquid cooling drive 410 is connected to the first sliding door 420 to drive the first sliding door 420 to open or close the frozen liquid nitrogen storage tank 102. Before the batteries need to be shelled, the battery positioning tray 20 and multiple batteries are placed in the frozen liquid nitrogen storage tank 102. At this time, the liquid cooling drive 410 drives the first sliding door 420 to open the frozen liquid nitrogen storage tank 102, allowing the liquid nitrogen in the frozen liquid nitrogen storage tank 102 to freeze multiple batteries simultaneously. After the battery is removed from the frozen liquid nitrogen storage tank 102 , the liquid cooling drive 410 drives the first sliding door 420 to close the frozen liquid nitrogen storage tank 102 , so that the liquid nitrogen in the frozen liquid nitrogen storage tank 102 is well sealed and stored, thereby ensuring the freezing performance of the frozen liquid nitrogen storage tank 102 .

[0021] In one embodiment, the suspension and transport mechanism 200 is located above the base 100 and is mounted on the inner top wall of the vehicle body. The suspension and transport mechanism 200 is used to loosen or clamp the battery positioning tray 20, thereby transporting the battery positioning tray 20 from the loading mechanism 300 to the frozen liquid nitrogen storage tank 102 and the positioning and transport mechanism 500. Specifically, first, multiple batteries are positioned and placed on the battery positioning tray 20; secondly, the loading mechanism 300 transports the battery positioning tray 20 to a predetermined position; then, the liquid-cooled drive 410 drives the first sliding door 420 to open the frozen liquid nitrogen storage tank 102; then, the suspension and transportation mechanism 200 clamps the battery positioning tray 20 from the loading mechanism 300 and transports it to the frozen liquid nitrogen storage tank 102 for freezing; then, the suspension and transportation mechanism 200 transports the frozen battery positioning tray 20 from the frozen liquid nitrogen storage tank 102 to the positioning and transportation mechanism 500; then, the liquid-cooled drive 410 drives the first sliding door 420 to close the frozen liquid nitrogen storage tank 102; then, the battery positioning tray 20 is transported by the positioning and transportation mechanism 500.

[0022] In this embodiment, a positioning and conveying mechanism 500 is mounted on the base 100 and is used to position and convey the battery positioning tray 20. The vehicle-mounted battery recycling equipment 10 also includes a shelling mechanism 1100 and a coring mechanism 1200, which are arranged sequentially along the conveying direction of the positioning and conveying mechanism 500. The shelling mechanism 1100 is used to shell the batteries in the battery positioning tray 20, enabling the shelling mechanism 1100 to simultaneously perform batch shelling operations on multiple batteries in the battery positioning tray 20. The coring mechanism 1200 is used to remove the cores of the batteries from the battery positioning tray 20 after shelling, enabling the coring mechanism 1200 to simultaneously perform batch removal operations on multiple batteries in the battery positioning tray 20.

[0023] The above-mentioned vehicle-mounted battery recycling equipment 10 loads multiple batteries through the battery positioning tray 20. When the battery positioning tray 20 after loading the batteries is transported to the first predetermined position by the loading mechanism 300, the liquid-cooled driving component 410 drives the first sliding door 420 to open the frozen liquid nitrogen storage tank 102. The suspension conveying mechanism 200 first clamps the battery positioning tray 20 from the loading mechanism 300 and transports it to the frozen liquid nitrogen storage tank 102 for freezing. The frozen battery positioning tray 20 is then transported from the frozen liquid nitrogen storage tank 102 to the positioning and conveying mechanism 500. The positioning and conveying mechanism 500 then positions the battery positioning tray 20 and sequentially transports it to the positions corresponding to the shelling mechanism 1100 and the coring mechanism 1200, so that the multiple batteries on the battery positioning tray 20 are first subjected to a batch shelling operation by the shelling mechanism 1100, and then a batch core removal operation is performed by the coring mechanism 1200, thereby realizing batch battery recycling. Because the batteries are frozen before being shelled, the battery temperature is lower when the shells are removed, which reduces the risk of the batteries catching fire due to excessively high temperatures during shelling. Compared with the traditional method of discharging first and then shelling and removing the battery cells, the efficiency of battery recycling is improved, and at the same time, the problem of low battery material recovery rate and greater separation difficulty caused by charged battery crushing is avoided.

[0024] As shown in Figures 1 and 2, in one embodiment, the vehicle-mounted battery recycling equipment 10 further includes a precooling mechanism 600, which includes a precooling drive 610 and a second sliding door 620. The base 100 is provided with a precooling liquid nitrogen storage tank 106 and a second chute 107. The precooling liquid nitrogen storage tank 106 is connected to the second chute 107. The precooling drive 610 is mounted on the base 100. The second sliding door 620 is located in the second chute 107 and is slidably connected to the base 100. The power output end of the precooling drive 610 is connected to the second sliding door 620 to drive the second sliding door 620 to open or close the precooling liquid nitrogen storage tank 106. In this embodiment, the loading mechanism 300, the precooling mechanism 600, the liquid cooling mechanism 400, and the positioning and conveying mechanism 500 are sequentially arranged along the suspension transport mechanism 200. When the battery positioning tray 20 is transported to the first predetermined position by the loading mechanism 300, the battery positioning tray 20 and the multiple batteries are first placed in the pre-cooling liquid nitrogen receiving tank 106. At this time, the pre-cooling driving component 610 drives the second sliding door 620 to open the pre-cooling liquid nitrogen receiving tank 106, so that the liquid nitrogen in the pre-cooling liquid nitrogen receiving tank 106 can pre-freeze the multiple batteries at the same time; then the battery positioning tray 20 and the multiple batteries are placed in the frozen liquid nitrogen receiving tank 102. At this time, the liquid cooling driving component 410 drives the first sliding door 420 to open the frozen liquid nitrogen receiving tank 102, so that the liquid nitrogen in the frozen liquid nitrogen receiving tank 102 can freeze the multiple batteries at the same time, so that the multiple batteries on the same battery positioning tray 20 are pre-frozen and then frozen before being shelled, thereby better freezing the multiple batteries on the same battery positioning tray 20.

[0025] It should be noted that after the battery is removed from the pre-cooling liquid nitrogen storage tank 106, the pre-cooling driver 610 drives the second sliding door 620 to close the pre-cooling liquid nitrogen storage tank 106, so that the liquid nitrogen in the pre-cooling liquid nitrogen storage tank 106 is well sealed and stored, ensuring the freezing performance of the pre-cooling liquid nitrogen storage tank 106. Similarly, after the battery is removed from the frozen liquid nitrogen storage tank 102, the liquid cooling driver 410 drives the first sliding door 420 to close the frozen liquid nitrogen storage tank 102, so that the liquid nitrogen in the frozen liquid nitrogen storage tank 102 is well sealed and stored, ensuring the freezing performance of the frozen liquid nitrogen storage tank 102.

[0026] As shown in Figures 1 and 5 , in one embodiment, the vehicle-mounted battery recycling device 10 further includes a heat dissipation mechanism 700, which includes a serpentine heat dissipation elbow 710, a fixing plate 720, and a cooling fan 730. The fixing plate 720 is mounted on the side wall of the base 100, and the serpentine heat dissipation elbow 710 is mounted on the top of the fixing plate 720. The two ends of the serpentine heat dissipation elbow 710 are respectively connected to the frozen liquid nitrogen storage tank 102 and the pre-cooled liquid nitrogen storage tank 106, so that the liquid nitrogen in the pre-cooled liquid nitrogen storage tank 106 flows into the frozen liquid nitrogen storage tank 102 through the serpentine heat dissipation elbow 710. In this embodiment, the fixing plate 720 is provided with a through hole 722. A cooling fan 730 is located within the through hole 722 and connected to the fixing plate 720. The cooling fan 730 is used to dissipate heat from the serpentine heat dissipation elbow 710. Specifically, the cooling fan 730 dissipates heat from the outer surface of the serpentine heat dissipation elbow 710 through the through hole 722, thereby reducing temperature difference losses in the serpentine heat dissipation elbow 710 during the liquid nitrogen transportation process. Because the multiple batteries of the battery positioning tray 20 are pre-frozen in the liquid nitrogen in the pre-cooled liquid nitrogen storage tank 106, the liquid nitrogen loss in the pre-cooled liquid nitrogen storage tank 106 is greater than the liquid nitrogen in the frozen liquid nitrogen storage tank 102. Therefore, the liquid nitrogen in the frozen liquid nitrogen storage tank 102 can be replenished to the pre-cooled liquid nitrogen storage tank 106.

[0027] As shown in Figures 1 and 5, in one embodiment, the heat dissipation mechanism 700 further includes a pump body 740 and a first liquid level sensor 750. The pump body 740 is provided on the serpentine heat dissipation elbow 710, and the first liquid level sensor 750 is installed on the inner wall of the pre-cooling liquid nitrogen receiving tank 106. The first liquid level sensor 750 is electrically connected to the control end of the pump body 740. When the liquid nitrogen in the pre-cooling liquid nitrogen receiving tank 106 is lower than the first predetermined liquid level, the first liquid level sensor 750 generates a sensing signal, and the pump body 740 is started to transport the liquid nitrogen in the frozen liquid nitrogen receiving tank 102 to the pre-cooling liquid nitrogen receiving tank 106. Otherwise, the first liquid level sensor 750 does not generate a sensing signal, and the pump body 740 is not started. In this way, the liquid nitrogen in the frozen liquid nitrogen receiving tank 102 is automatically replenished to the pre-cooling liquid nitrogen receiving tank 106.

[0028] As shown in Figures 1 to 5, in one embodiment, the on-board battery recycling device 10 further includes a liquid nitrogen replenishing mechanism 800 and a second liquid level sensor 900. The liquid nitrogen replenishing mechanism 800 is mounted on the outer wall of the base 100 and is in communication with the frozen liquid nitrogen storage tank 102. The second liquid level sensor 900 is mounted on the inner wall of the pre-cooled liquid nitrogen storage tank 106 and is electrically connected to a control terminal of the liquid nitrogen replenishing mechanism 800. When the liquid nitrogen in the frozen liquid nitrogen storage tank 102 falls below a second predetermined liquid level, the second liquid level sensor 900 generates a sensing signal, and the liquid nitrogen replenishing mechanism 800 replenishes the frozen liquid nitrogen storage tank 102. Otherwise, the second liquid level sensor 900 does not generate a sensing signal, and the liquid nitrogen replenishing mechanism 800 does not replenish the frozen liquid nitrogen storage tank 102. In this embodiment, the liquid nitrogen replenishing mechanism 800 includes a liquid nitrogen source 810 and an on-off control valve 820. The liquid nitrogen source 810 is in communication with the pre-cooled liquid nitrogen storage tank 106. The on-off control valve 820 is disposed on a pipeline connecting the liquid nitrogen source 810 and the pre-cooled liquid nitrogen storage tank 106. A second liquid level sensor 900 is electrically connected to a control end of the on-off control valve 820. When the liquid nitrogen in the refrigerated liquid nitrogen storage tank 102 falls below a second predetermined liquid level, the second liquid level sensor 900 generates a sensing signal, and the on-off control valve 820 opens, allowing the liquid nitrogen source 810 to replenish the refrigerated liquid nitrogen storage tank 102. Otherwise, the second liquid level sensor 900 does not generate a sensing signal, and the on-off control valve 820 closes, and the liquid nitrogen source 810 does not replenish the refrigerated liquid nitrogen storage tank 102.

[0029] As shown in Figures 1 and 3, in one embodiment, the suspension and transport mechanism 200 includes a top seat 210, a suspension and translation assembly 220, a vertical lifting assembly 230 and a clamping claw assembly 240. The top seat 210 is fixed to the inner top wall of the vehicle body, the suspension and translation assembly 220 is installed on the top seat 210, the vertical lifting assembly 230 is installed at the power output end of the suspension and translation assembly 220, and the clamping claw assembly 240 is installed at the power output end of the vertical lifting assembly 230. The clamping claw assembly 240 is used to loosen or clamp the outer wall of the battery positioning plate 20, so that the suspension and transport mechanism 200 can loosen or clamp the outer wall of the battery positioning plate 20. In this embodiment, when the loading mechanism 300 transports the battery positioning tray 20 to the first predetermined position, the vertical lifting assembly 230 is first transported to the top of the first predetermined position along with the suspension translation assembly 220; then the power output end of the vertical lifting assembly 230 drives the clamping claw assembly 240 to descend to a first height above the first predetermined position; then the clamping claw assembly 240 is clamped on the outer wall of the battery positioning tray 20; then the vertical lifting assembly 230 is transported to the top of the frozen liquid nitrogen storage tank 102 along with the suspension translation assembly 220; then the power output end of the vertical lifting assembly 230 drives the clamping claw assembly 240 to descend into the frozen liquid nitrogen storage tank 102, so that the frozen liquid nitrogen storage tank 102 is 02 freezes the multiple batteries on the battery positioning tray 20; then the power output end of the vertical lifting component 230 drives the clamping claw component 240 to rise to the first predetermined position above the frozen liquid nitrogen storage tank 102; then the vertical lifting component 230 is transported to the top of the positioning and conveying mechanism 500 along with the suspension translation component 220; then the power output end of the vertical lifting component 230 drives the clamping claw component 240 to descend to a second height above the positioning and conveying mechanism 500; then the clamping claw component 240 releases the battery positioning tray 20, so that the battery positioning tray 20 is positioned on the positioning and conveying mechanism 500, and then the positioning and conveying mechanism 500 continues to convey the battery positioning tray 20.

[0030] It should be noted that, in one embodiment, the vehicle-mounted battery recycling equipment 10 is additionally provided with a pre-cooling mechanism 600, the feeding mechanism 300, the pre-cooling mechanism 600, the liquid cooling mechanism 400 and the positioning and conveying mechanism 500 are sequentially arranged along the suspension and conveying mechanism 200. After the step of clamping the claw assembly 240 on the outer wall of the battery positioning plate 20, the vertical lifting assembly 230 is first transported to the top of the pre-cooling liquid nitrogen storage tank 106 along with the suspension translation assembly 220, and the power output end of the vertical lifting assembly 230 drives the claw assembly 240 to descend to The liquid nitrogen in the pre-cooling liquid nitrogen storage tank 106 is used to pre-freeze the multiple batteries on the battery positioning tray 20; the vertical lifting assembly 230 then drives the clamping claw assembly 240 to rise above the pre-cooling liquid nitrogen storage tank 106; then, the vertical lifting assembly 230 is transported to the top of the frozen liquid nitrogen storage tank 102 along with the suspension translation assembly 220, etc. The difference is that the suspension transportation mechanism 200 needs to be adapted to add a step of transporting the multiple batteries on the battery positioning tray 20 to the pre-cooling liquid nitrogen storage tank 106 for pre-cooling.

[0031] As shown in Figures 1 and 3, in one embodiment, the clamping jaw assembly 240 includes a dual-drive cylinder 242, a first clamping jaw 244, and a second clamping jaw 246. The dual-drive cylinder 242 is mounted on the vertical lifting assembly 230. The first clamping jaw 244 and the second clamping jaw 246 are both mounted on the power output end of the dual-drive cylinder 242, so that the dual-drive cylinder 242 drives the first clamping jaw 244 and the second clamping jaw 246 to move toward or away from each other. A first clamping groove 24 and a second clamping groove 26 are respectively defined on both sides of the battery positioning plate 20. The first clamping jaw 244 is used to abut against the first clamping groove 24 when clamping the battery positioning plate 20, and the second clamping jaw 246 is used to abut against the second clamping groove 26 when clamping the battery positioning plate 20. When the clamping jaw assembly 240 clamps and positions the battery positioning plate 20 , the dual-drive cylinder 242 drives the first clamping jaw 244 and the second clamping jaw 246 toward each other, so that the first clamping jaw 244 abuts the first clamping groove 24 , and the second clamping jaw 246 abuts the second clamping groove 26 .

[0032] As shown in Figures 1, 3, and 4, in one embodiment, the first clamping jaw 244 and the second clamping jaw 246 are both inclined toward each other, allowing the first clamping jaw 244 to better abut against the first clamping groove 24, while simultaneously allowing the second clamping jaw 246 to better abut against the second clamping groove 26. In one embodiment, the battery positioning tray 20 further defines a first immersion liquid hole 27, which is connected to the plurality of positioning grooves 22, respectively. This allows the battery positioning tray 20 to quickly contact the liquid nitrogen when placed in the pre-cooling liquid nitrogen storage tank 106 or the frozen liquid nitrogen storage tank 102, thereby improving the freezing effect of each battery.

[0043] Compared with the related art, the present disclosure has the following advantages including but not limited to:

[0044] 1. The above-mentioned vehicle-mounted battery recycling equipment 10 loads multiple batteries through the battery positioning tray 20. When the battery positioning tray 20 loaded with batteries is transported to the first predetermined position by the loading mechanism 300, the liquid cooling drive member 410 drives the first sliding door 420 to open the frozen liquid nitrogen storage tank 102. The suspension conveying mechanism 200 first clamps the battery positioning tray 20 from the loading mechanism 300 and transports it to the frozen liquid nitrogen storage tank 102 for freezing. The frozen battery positioning tray 20 is then transported from the frozen liquid nitrogen storage tank 102 to the positioning and conveying mechanism 500. The positioning and conveying mechanism 500 then transports the battery positioning tray 20 in sequence to the positions corresponding to the shelling mechanism 1100 and the coring mechanism 1200, respectively. The multiple batteries on the battery positioning tray 20 are first subjected to a batch shelling operation by the shelling mechanism 1100, and then the batch core removal operation is carried out by the coring mechanism 1200, thereby realizing batch battery recycling.

[0045] 2. Because the batteries are frozen before being shelled, the battery temperature is lower when the shells are removed, which reduces the risk of the batteries catching fire due to excessively high temperatures during shelling. Compared with the traditional method of discharging first and then shelling and removing the battery cells, the efficiency of battery recycling is improved, and the problem of low battery material recovery rate and greater separation difficulty caused by charged battery crushing is avoided.

[0046] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. The above-mentioned embodiments only express several implementation methods of the present disclosure. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the present disclosure, several variations and improvements can be made, which all fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the patent of the present disclosure shall be based on the attached claims.
