Description

Technical Field

[0001] The present invention relates to the technical field of battery recycling, and in particular to a device and method for disassembling and recycling waste lithium batteries. Background Art

[0002] Lithium battery is a primary battery with lithium metal or lithium alloy as negative electrode material and non-aqueous electrolyte solution. It is different from rechargeable lithium-ion battery and lithium-ion polymer battery. The inventor of lithium battery is Edison. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium battery has not been used for a long time. With the development of microelectronics technology in the late 20th century, the number of miniaturized devices has increased, which puts high demands on power sources. Lithium battery has entered the large-scale practical stage.

[0003] After searching, the patent application document with the prior art publication number CN111162338B discloses a waste lithium battery pack disassembly and recycling equipment, including a bottom plate, a side plate, a conveying assembly, a moving mechanism, a first cutting mechanism, a second cutting mechanism and a waste collection box. The present invention conveys the square lithium battery forward through the conveying assembly in the first guide rail and the second guide rail. When it moves to the end of the first guide rail, the middle two sides of the lithium battery are fixed by the pressing block in the rotating shell, and then the first screw rod drives the lithium battery to move through the first moving block, the vertical axis and the fixed sleeve, and the battery is cut by the first cutting mechanism, the second cutting mechanism and the waste is collected in turn. After the battery is disassembled, different parts are collected by the waste collection box, and the electrolyte enters the bottom of the waste collection box through the partition net in the sub-collection tank during the disassembly process, and is collected separately from the solid structure, so as to facilitate the subsequent processing of the battery waste.

[0047] By setting the above technical scheme, water is sprayed on the top of the crushing roller 504 according to the effect of the reciprocating outflow of water inside the water storage tank 605, so that when the crushing roller 504 crushes the waste lithium batteries, the dust generated during the crushing is reduced, which is convenient for the staff to continuously add materials around it, improves the work efficiency of the staff, and reduces the harm to the surrounding environment. At the same time, according to the effect of the reciprocating outflow of water, the consumption of water resources is reduced, and the spray hole is prevented from always facing the top of the crushing roller 504, which reduces the residue of the crushed waste lithium batteries adhering to the spray hole, affecting the water output efficiency of the spray hole;

[0048] like Figure 1 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 As shown, the ventilation screening mechanism for screening and classifying the crushed battery residues is located inside the recycling box 1, and the ventilation screening mechanism includes a rotating rod 8, and the outer wall of the rotating rod 8 is fixedly connected with a plurality of rotating blocks 807, and the plurality of rotating blocks 807 are located inside the recycling box 1, and the outer walls of the plurality of rotating blocks 807 are fixedly connected with a plurality of rotating plates 808, and the ends of the plurality of rotating plates 808 away from the rotating blocks 807 are fixedly connected with a second magnetic block 809;

[0049] Further, square slide grooves 801 are provided on both sides of the inner wall of the recycling box 1, and a fixed vertical rod 802 is fixedly connected inside the square slide groove 801, and a telescopic spring 803 is fixedly connected to the bottom of the inner wall of the square slide groove 801, and the outer wall of the fixed vertical rod 802 is slidably connected to a limit slider 804, and a screening plate 805 is fixedly connected between the two limit sliders 804, and a first magnetic block 806 is fixedly connected to the bottom of the screening plate 805, and the rotating rod 8 is rotatably connected to the inside of the recycling box 1, and a third rotating groove is provided on the recycling box 1, and the rotating rod 8 is rotatably connected to the recycling box 1 through the third rotating groove, and one end of the rotating rod 8 is rotatably extended to the outside of the recycling box 1 through the third rotating groove;

[0050] Furthermore, the rotating shaft 501 is connected to the reciprocating screw 601 through a first transmission belt transmission, the rotating shaft 501 is connected to the rotating rod 8 through a second transmission belt transmission, the first magnetic block 806 and the second magnetic block 809 are arranged to attract each other with opposite poles, the end of the telescopic spring 803 away from the square slide 801 is connected to one side of the limit slider 804, the outer wall of the limit slider 804 and the inner wall of the square slide 801 are arranged to slide and fit, the telescopic spring 803 is located on the outer side of the fixed vertical rod 802, and a plurality of screening holes are provided on the screening plate 805;

[0051] By setting the above technical solution, since the recycled waste lithium batteries contain many components, such as plastics and metal parts, when crushing, the plastic parts have a lower strength, a higher degree of crushing, and smaller particles, while the metal parts have a higher strength, a lower degree of crushing, and larger particles. At this time, the screening plate 805 can be used to screen and classify the two, so that the staff can classify and collect the crushed waste lithium batteries, thereby improving the recycling efficiency of the staff;

[0052] After the waste lithium batteries are crushed, the bolts on the first mounting baffle 4 and the second mounting baffle 7 are removed, and the crushed waste can be taken out from the material taking port.

[0053] like Figure 1-9 As shown, in the present invention, the working principle of the waste lithium battery disassembly and recycling device and method is as follows: when the waste lithium battery needs to be disassembled, crushed and recycled, the waste lithium battery is first thrown above the crushing roller 504, and then the servo motor 5 is turned on. When the servo motor 5 works, it drives the rotating shaft 501 to rotate. When the rotating shaft 501 rotates, it drives the multiple transmission shafts 502 to rotate according to the action of the multiple rotating gears 503, thereby driving the multiple crushing rollers 504 to rotate, so that the waste lithium battery located above the crushing roller 504 is crushed and recycled, and the waste lithium battery residue after crushing falls on the top of the screening plate 805;

[0054] When the rotating shaft 501 rotates, the reciprocating screw 601 is driven to rotate according to the action of the first transmission belt, and the threaded block 602 is driven to reciprocate accordingly. In the initial state, the water tank 605 is located at the edge of the recovery box body 1, and the spraying hole on the outer wall of the water tank 605 is located above the water tank 605. When the threaded block 602 reciprocates, the water tank 605 is driven to reciprocate, and according to the meshing effect of the circular gear ring 607 and the teeth on the gear plate 606, the water tank 605 is driven to rotate, so that the spraying hole above the water tank 605 rotates with the rotation of the water tank 605. When the spraying hole rotates to the bottom of the water tank 605, the water inside the water tank 605 flows out. Otherwise, the water cannot flow out, so that the water inside the water storage tank 605 flows out reciprocatingly and flows to the top of the crushing roller 504. It should be noted that through the above arrangement, according to the effect of the reciprocating outflow of the water inside the water storage tank 605, water is sprayed on the top of the crushing roller 504, so that when the crushing roller 504 crushes the waste lithium batteries, the dust generated during the crushing is reduced, which is convenient for the staff to continuously add materials around it, improves the work efficiency of the staff, and reduces the harm to the surrounding environment. At the same time, according to the effect of the reciprocating outflow of water, the consumption of water resources is reduced, and it is also avoided that the spray hole is always facing the top of the crushing roller 504, which reduces the residue of the crushed waste lithium batteries adhering to the spray hole, affecting the water output efficiency of the spray hole;

[0055] When the rotating shaft 501 rotates, the rotating rod 8 is driven to rotate according to the second transmission belt. When the rotating rod 8 rotates, the rotating block 807 and the rotating plate 808 are driven to rotate accordingly. When the rotating plate 808 rotates, the second magnetic block 809 at its top rotates to the bottom of the first magnetic block 806. According to the effect of opposite poles attracting each other, the screening plate 805 slides downward. When the second magnetic block 809 is separated from the first magnetic block 806, the screening plate 805 returns to the initial position according to the telescopic spring 803, and generates a shaking effect, so that the residue of the crushed waste lithium battery above the screening plate 805 is shaken and dropped. At the same time, when the rotating plate 808 rotates, according to its rotating blowing effect, the lower part of the interior of the recovery box 1 is ventilated and dried, so as to increase the air-drying effect of the waste lithium battery after water.

[0056] Since the recycled waste lithium batteries contain many components, such as plastics and metal parts, when they are crushed, the plastic parts have a lower strength, a higher degree of crushing, and smaller particles, while the metal parts have a higher strength, a lower degree of crushing, and larger particles. At this time, the screening plate 805 can be used to screen and classify the two, so that the staff can classify and collect the crushed waste lithium batteries, thereby improving the recycling efficiency of the staff;

[0057] After the waste lithium batteries are crushed, the bolts on the first mounting baffle 4 and the second mounting baffle 7 are removed, and the crushed waste can be taken out from the material taking port.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
