Description

A battery crushing device Technical Field

[0001] The present disclosure relates to the technical field of battery crushing, and in particular to a battery crushing device. Background Art

[0002] Discarded lithium-ion batteries are more hazardous than other types of batteries. They pose safety risks during storage and transportation, and fire and explosion accidents are common. Collected batteries are usually processed centrally by recycling companies in newly built factories. However, the overall quality of battery recycling companies in the industry is poor. More than 80% of these companies are small workshops with simple equipment and backward technology. They engage in extensive battery recycling operations, resulting in a large amount of resource waste and serious environmental pollution.

[0003] Battery recycling centers are unable to implement safety measures when encountering these types of batteries. Even after the batteries are returned to the manufacturer, many fail to implement specific treatment measures for these types of batteries. Instead, they simply leave them alone or soak them in water after discovering a problem, without proactive intervention and only disassembling them after a long time. Furthermore, the entire processing process is not centralized, requiring multiple transfers of batteries. There are no automatic fire alarms, temperature and smoke monitoring, temperature controls, or dedicated wastewater and gas treatment equipment. This transfer process can cause environmental pollution and create new safety hazards. Some manufacturers may designate dedicated disposal areas, isolated by explosion-proof walls. This results in large spaces, inconvenient relocation, and high overall costs.

[0004] In order to solve the above technical problems, China Patent Publication No. CN213052057U is a mobile waste battery safety disposal cabinet. The explosion-proof air conditioner in the placement area cools down the waste batteries that are initially determined to be in Class B warning status, and performs temperature sensing, smoke sensing, and dangerous gas detection. For waste batteries without abnormalities, they can be safely placed in the placement area for disassembly. Batteries with abnormalities in Class B dangerous status are transferred to the soaking area for soaking before disassembly. Batteries that are initially determined to be in Class B dangerous status are directly soaked in the soaking area, and there is dangerous gas detection. This disposal method greatly improves safety; by setting explosion-proof fans and ventilation windows, each area is well ventilated and safe, exhaust gas is sucked away for treatment and then discharged, wastewater is collected in the waste liquid collection tank and then passed into the wastewater treatment equipment for treatment, avoiding pollution to the environment; by making it into a box-type structure, including a placement area, a soaking area, a disassembly area and a washing area, the disposal of waste batteries is highly concentrated, and it is also convenient for overall transportation, short or long-distance transportation.

[0005] In the actual production process: 1. Currently, the model standards of lithium battery packs and battery modules are different, and the structure and size of battery cells vary. The current recycling technology can only mechanically disassemble battery cells. Both battery packs and battery modules need to be manually disassembled into single cells before entering the crusher, otherwise they are prone to fire. 2. The closed-loop battery recycling industry chain is imperfect, lacking full-process lithium battery recycling technology. The full-process lithium battery recycling process is complex and the investment cost is high. Therefore, most recycling companies only carry out physical separation of waste lithium batteries and high-temperature pyrolysis to recover positive electrode materials, copper, and aluminum metals in a short period of time. The recycling process is short, there is secondary pollution, the metal recovery rate is not high, and the purity and value of the recycled products are low, so improvements are needed.

[0027] The beneficial effects of the present disclosure are:

[0028] 1. The crushing box can effectively shield and avoid direct contact with the outside, and can extract liquids such as electrolyte in the crushing box, which can avoid the appearance of liquid in the subsequent crushing process and improve the safety of crushing; the dust suction device can make the gas flow, and the directional flow of gas can make the dust generated when disassembling the battery move in a directional manner, which can effectively ensure the safety of crushing; the crushing device can crush the battery after the liquid is extracted, which is convenient for subsequent processing; the nitrogen supply device can fill the crushing box with gas, which can improve the safety of use and avoid explosions.

The addition of nitrogen can prevent the battery from exploding during crushing and disassembly.

[0029] 2. In actual use, batteries are placed in the material box and fall on the lower end of the belt conveyor assembly. The batteries can be transported by the belt conveyor assembly. The belt conveyor assembly is tilted to facilitate the rise of the batteries, so that the batteries can be transported into the crushing box through the conveyor plate. At the same time, in actual use, a scraping component is installed on the upper end of the conveyor plate, and a rubber plate is set. At the same time, the rubber plate can be raised and lowered and disassembled, which can well contact the lower end of the belt conveyor assembly, thereby avoiding impurities remaining on it and allowing impurities to enter the crushing box through the conveyor plate.

[0030] 3. During operation, when the battery needs to enter the crushing box, the sealing plate does not correspond to the feed port, allowing the battery to enter the crushing box through the feed port. After the battery enters, the cylinder assembly operates to move the U-shaped connecting rod, which can rotate the rocker arm. The rotation of the rocker arm can move the sealing plate, which can move to seal the feed port and effectively isolate it from the outside.

[0031] 4. After the battery enters the crushing chamber through the feed port, it can fall onto the carrying plate. The battery will put pressure on the carrying plate, which can stretch the first return spring member and the second return spring member. At the same time, the damping member can be extended and retracted to bear the external force. At the same time, the rotating connection facilitates the rotation of the carrying plate, which can make the battery on the carrying plate fall. The function of the carrying plate can prevent the battery from directly contacting the bottom of the crushing chamber and preventing the battery from being crushed.

[0032] 5. During actual operation, the second electric telescopic assembly enables the lead screw nut to rotate the lead screw, which facilitates the rotation of the lead screw. The lead screw rotates the movable rail, which facilitates the adjustment of the structural position of the battery so that the liquid in the battery can be extracted through a needle-shaped straw at a later time. At the same time, the third electric telescopic assembly can enable the spur rack to drive the gear part to rotate so as to drive the splint part to move to clamp and rotate the battery.

[0033] 6. By inserting a needle-shaped straw into the battery and extracting the liquid inside, it helps to improve the safety of the battery during crushing. Extracting the liquid before crushing can recycle the electrolyte. On the other hand, the solids can be transported out uniformly after disassembly for easy unified treatment. At the same time, the presence of liquid will not affect transportation, and the early extraction of liquid also avoids environmental pollution. The nitrogen supply assembly can supply gas to the gas supply plate, allowing nitrogen to quickly enter the crushing box, which can increase the nitrogen content in the crushing box. At the same time, it can also squeeze the nitrogen and let it fall, and be discharged through the exhaust component connected to the crushing box. The detection assembly can also detect the nitrogen content in the crushing box.

[0034] 7. The second motor assembly can rotate the support shaft under the action of the synchronous wheel and the synchronous belt. In actual use, the synchronous wheel and the synchronous belt adopt a toothed structure to ensure the stability of power transmission, and the filter mesh can effectively filter the waste powder to better improve safety;

[0035] The first motor assembly can drive one of the gear parts to rotate, and the two gear parts are engaged and rotate in opposite directions, so that the two crushing roller parts rotate to crush the batteries. After the crushing is completed, the battery waste can be transported in a direction through the auger part after falling. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In some embodiments, the batteries to be crushed are transported to the crushing box 2 for crushing through the conveying device 1. The batteries are placed in the material box 12 and fall on the lower end of the belt conveyor assembly 11. The batteries can be transported by the belt conveyor assembly 11. The belt conveyor assembly 11 is tilted to facilitate the rise of the batteries, so that the batteries can be transported into the crushing box 2 through the conveying plate 13. At the same time, in actual use, a scraping component is installed on the upper end of the conveying plate 13, and a rubber plate is provided. At the same time, the rubber plate can be raised and lowered and disassembled, which can well contact the lower end of the belt conveyor assembly 11, thereby avoiding impurities remaining thereon, so that impurities can enter the crushing box 2 through the conveying plate 13. After the batteries enter the crushing chamber 5 through the feed port 21, the batteries can fall onto the supporting plate 31. The batteries will pressurize the supporting plate 31, which can stretch the first return spring member 33 and the second return spring member 35. At the same time, the damping member 34 can be retracted to bear external force, and the rotating connection can facilitate the rotation of the supporting plate 31. The movement can cause the batteries on the supporting plate 31 to fall. The supporting plate 31 can prevent the batteries from directly contacting the bottom of the crushing chamber 5 and being crushed. When the batteries need to enter the crushing box 2, the sealing plate 22 does not correspond to the feed port 21, allowing the batteries to enter the crushing box 2 through the feed port 21. When the batteries enter, the cylinder assembly 4 can operate to move the U-shaped connecting rod 25, which can rotate the rocker arm 24. The rotation of the rocker arm 24 can move the sealing plate 22, and the sealing plate 22 can move to seal the feed port 21, which can effectively isolate it from the outside, effectively improve the safety of disassembling the battery, and avoid affecting the staff. After entering the crushing box 2, the shock absorber 3 is first used to reduce shock to prevent the batteries from being directly broken. The nitrogen inflation device 8 injects nitrogen from the top to discharge the oxygen in the crushing chamber 5 and the dust suction device 10 into the gas collection chamber at the bottom of the crushing chamber. The second motor assembly 104 can rotate the support shaft 106 under the action of the synchronous wheel 103 and the synchronous belt 105.

[0056] In actual use, the synchronous wheel 103 and the synchronous belt 105 adopt a toothed structure, which can ensure the stability of power transmission, and the waste powder can be effectively filtered through the filter mesh 108 to better improve safety. A detection component 83 is installed on the side wall of the lower end of the crushing chamber. The nitrogen is stopped from being pumped in until the concentration of nitrogen in the crushing chamber and the dust absorption chamber reaches more than 97%. The entry of nitrogen can prevent the battery from exploding during the crushing process and causing safety hazards. The nitrogen supply component 81 can supply gas to the gas supply plate 82, which can quickly enter the crushing box 2 and increase the nitrogen content in the crushing box 2. At the same time, the nitrogen can be squeezed and dropped, and discharged through the exhaust gas component connected to the crushing box 2. The nitrogen content in the crushing box 2 can be detected by the detection component 83. The cylinder assembly 4 withdraws the shock absorber 3 so that the battery falls into the crushing chamber 5 from the shock absorber 3. The third electric telescopic component clamping device 6 in the crushing chamber 5 that can extend up and down and forward and backward clamps the battery.

[0057] In actual operation, the second electric telescopic assembly 62 enables the screw nut 63 to rotate the screw member 64, which facilitates the rotation of the screw 64. The screw 64 rotates the movable rail member 68 to facilitate the adjustment of the structural position of the battery so that the liquid in the battery can be extracted through the needle-shaped pipette 72 later. At the same time, the third electric telescopic assembly 613 can enable the spur rack 612 to drive the gear member 611 to rotate so as to drive the clamping member 69 to move and clamp the battery. The front end of the liquid suction device 7 is equipped with multiple needle-shaped pipettes 72. The needle-shaped pipettes 72 are inserted into the battery to suck out the liquid electrolyte in the battery. Then the crushing device 9 moves to crush the battery. The dust generated during the crushing process is collected by the dust collection device 10. The first motor assembly 95 can drive one of the gear parts 96 to rotate. The two gear parts 96 are meshed and the two gear parts 96 rotate in opposite directions, so that the two crushing roller parts 93 rotate to crush the battery. When the crushing is completed, the battery waste can be transported in a direction through the auger part 94 after falling, and the crushed battery fragments are transported to a designated location for unified treatment. The crushing box 2 can effectively block it and avoid direct contact with the outside. Liquids such as the electrolyte in the crushing box 2 can be extracted to avoid the appearance of liquid in the subsequent crushing process, thereby improving the safety of the crushing.
