Description

Technical Field

[0001] The utility model relates to the technical field of battery recycling, in particular to a waste lithium battery dismantling device. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. They can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. They are easy to use, highly safe, and widely used in various areas of our lives. However, existing lithium-ion batteries have a limited lifespan, and scrapped lithium-ion batteries contain large amounts of heavy metals. Whether the lithium-ion batteries are buried deep underground or exposed to the atmosphere, the heavy metals in the lithium-ion batteries will seep into the ground, causing environmental pollution.

[0003] For example, the Chinese utility model patent with announcement number: CN218903041 U discloses a dismantling and recycling device for waste lithium batteries, and its technical solution is: it includes a crushing mechanism, a solid-liquid separation mechanism and a conveying mechanism. The solid-liquid separation mechanism includes a separation box, a filter plate fixed in the separation box, and a pressing assembly and a pushing assembly arranged in the separation box. The crushing mechanism and the conveying mechanism are respectively connected to the feed port and the discharge port on the separation box. The pressing assembly is located directly above the filter plate, and the pushing assembly is located above the filter plate and extends horizontally toward the discharge port.

[0004] After searching by the applicant, it was found that there are still some problems in the above technical solution that need to be improved. For example, when crushing lithium batteries, the lithium batteries are first placed in the opening on the crushing box, and then the lithium batteries are crushed by two crushing rollers. However, in the crushing process, because the lithium batteries are moved between the crushing rollers of the chain under the action of gravity for crushing, when there are many lithium batteries, it is easy to cause the lithium batteries to get stuck, resulting in the lithium batteries being unable to move between the two crushing rollers for crushing, thereby causing the two crushing rollers to idle. For this reason, we propose a waste lithium battery dismantling device to solve the above problems. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 In this embodiment, a waste lithium battery dismantling device includes a crushing box 1 and an extrusion block 2 for squeezing the lithium battery. Slide grooves are provided at both ends of the crushing box 1, and guide plates 3 are fixed at both ends of the inner cavity of the crushing box 1. The bottom surface of the crushing box 1 is in a missing shape; a crushing component 4: the crushing component 4 is arranged on the front and inside of the crushing box 1; a feeding component 5: the feeding component 5 is arranged at both ends of the crushing box 1.

[0024] See also Figure 2 and Figure 3 In order to crush the lithium battery, the crushing assembly 4 in this embodiment includes a connecting box 401 fixed to the front of the crushing box 1, and a crushing motor 402 is fixed to the front of the connecting box 401. The output shaft of the crushing motor 402 is fixed to a rotating shaft 403. A first gear 404 is fixed to the outer surface of the rotating shaft 403. The right end of the first gear 404 is meshed with a second gear 405. A rotating rod 406 is fixed inside the second gear 405. The outer surfaces of the rotating rod 406 and the rotating shaft 403 are fixed with first sprockets 407. The outer surfaces of the two first sprockets 407 are both transmission-connected with first chains 408. The ends of the two first chains 408 away from the first sprocket 407 are both transmission-connected with first driven wheels 409. Connecting rods 410 are fixed to the inside of the two first driven wheels 409. The backs of the two connecting rods 410 pass through and extend into the crushing box 1 and are rotatably connected to it through bearings. Crushing rollers 411 are fixed to the outer surfaces of the two connecting rods 410.

[0025] The backs of the rotating shaft 403 and the rotating rod 406 are rotatably connected to the front of the crushing box 1 through bearings, and the top surface of the connecting box 401 is provided with two transmission holes for the two first chains 408 to pass through respectively.

[0026] When the lithium battery needs to be crushed, the crushing motor 402 is first started. When the output shaft of the crushing motor 402 rotates, it drives the shaft 403 fixed to the output shaft of the crushing motor 402 to rotate. During the rotation of the shaft 403, the first gear 404 fixed to the outer surface of the shaft 403 is driven to rotate. Because one end of the first gear 404 is also engaged with the second gear 405, the second gear 405 rotates in the opposite direction during the rotation of the first gear 404, and the second gear 405 drives the rotating rod 406 fixed therein to rotate. The first sprocket 407 rotates, and because the outer surfaces of the rotating shaft 403 and the rotating rod 406 are fixed with the first sprocket 407, the first sprocket 407 will rotate along with the rotating shaft 403 and the rotating rod 406, and the first sprocket 407 will drive the first driven wheel 409 to rotate through the first chain 408 set on the outer surface thereof, and further, each driven wheel 409 in the chain will drive the connecting rod 410 fixed thereto to rotate when it rotates, and when the connecting rod 410 rotates, it will drive the crushing roller 411 fixed on the outer surface of the connecting rod 410 to crush the lithium battery in the crushing box 1.

[0027] See also Figure 4In order to prevent the lithium battery from getting stuck during crushing, the feeding assembly 5 in this embodiment includes mounting boxes 501 fixed at both ends of the crushing box 1, and the two mounting boxes 501 are fixed with feeding motors 502 at the opposite ends. The output shafts of the two feeding motors 502 are fixed with second sprockets 503, and the outer surfaces of the second sprockets 503 are transmission-connected with second chains 504. The end of the second chain 504 away from the second sprocket 503 is transmission-connected with a second driven wheel 505, and a fixing rod 506 is fixed inside the second driven wheel 505. The two fixing rods 506 are opposite to each other. An eccentric disk 507 is fixed at one end, and an eccentric protrusion is fixed at the opposite end of the two eccentric disks 507. A hinge block 508 is rotatably connected to the eccentric disk 507, and the hinge block 508 is rotatably connected to the eccentric protrusion through a bearing. A pull rod 509 is hinged at the top of the hinge block 508, and a slider 510 is fixed between the two pull rods 509. The opposite ends of the two sliders 510 are respectively located inside the sliding grooves at both ends and are slidably connected thereto. A bracket 511 is fixed between the two pull rods 509, and the two ends of the extrusion block 2 are respectively fixed to the opposite ends of the two brackets 511.

[0028] When the lithium battery stored in the crushing box 1 is stuck, the feed motor 502 is started. When the output shaft of the feed motor 502 rotates, it drives the second sprocket 503 fixed to the output shaft of the feed motor 502 to rotate. The second chain 504 provided on the outer surface of the second sprocket 503 drives the second driven wheel 505 to rotate. During the rotation of the second driven wheel 505, the fixed rod 506 fixed inside the second driven wheel 505 is driven to rotate. The movable eccentric disk 507 rotates. During the rotation of the eccentric disk 507, the hinge block 508 provided on the eccentric disk 507 and rotatably connected to the eccentric disk 507 is driven to pull the pull rod 509. Under the limiting action of the slider 510 and the slide groove, the pull rod 509 can only move upward or downward. The bracket 511 fixed at one end of the two pull rods 509 drives the extrusion block 2 to move up and down, thereby squeezing the lithium batteries accumulated on the guide plate 3, avoiding the problem of idling of the two crushing rollers 411.
