Description

Technical Field

[0001] This utility model relates to the field of battery recycling technology, specifically to a waste lithium battery crushing and recycling device. Background Technology

[0002] Waste lithium battery crushing and recycling equipment is used to process waste lithium batteries. Through crushing, breaking down, and decomposing the batteries, valuable metals (such as lithium, cobalt, nickel, copper, and aluminum) and other materials (such as plastics and electronic components) are separated for subsequent recycling and processing. This equipment typically includes multiple processing steps to ensure that the battery materials can be recycled efficiently and environmentally.

[0003] Currently, shredded waste lithium batteries are typically processed in a decomposition tank containing strong acid (such as sulfuric acid) or strong alkali (such as sodium hydroxide) to dissolve the metals in the shredded waste lithium batteries. The dissolved metals are then extracted and stored. However, when shredded waste lithium batteries fall into the decomposition tank, the dissolving liquid in the tank is prone to splashing out. Because the dissolving liquid is highly corrosive, and the appropriate amount of liquid in the decomposition tank needs to be manually transported and replaced with handling equipment, workers are close to the decomposition tank. During the handling and replacement process, shredded waste lithium batteries are likely to fall onto the dissolving liquid in the decomposition tank, causing splashing and injury to workers.

[0004] Therefore, we propose a waste lithium battery crushing and recycling device. Utility Model Content

[0005] To address the aforementioned technical problems, this application provides a waste lithium battery crushing and recycling device, including a crushing box and a conveyor belt disposed below the crushing box. A dissolution and recycling box is disposed below one end of the conveyor belt. Two dissolution and recycling boxes are provided, and an alternation component is disposed below the two dissolution and recycling boxes. The alternation component is used to alternate the positions of the two dissolution and recycling boxes.

[0006] In some embodiments, the alternating assembly includes two first support plates disposed below the dissolution and recovery box. The upper end of the first support plate is provided with a first slide rail. The upper end surfaces of the two first slide rails are connected to a first support frame via sliders. Two second support plates are disposed between the two first support plates. The upper end surface of the second support plate is provided with a second slide rail.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 This utility model provides a technical solution:

[0023] A waste lithium battery crushing and recycling device includes a crushing box 1 and a conveyor belt 2 disposed below the crushing box 1. A dissolution and recycling box 3 is disposed below one end of the conveyor belt 2. There are two dissolution and recycling boxes 3. An alternation component 4 is disposed below the two dissolution and recycling boxes 3. The alternation component 4 is used to alternate the position of the two dissolution and recycling boxes 3.

[0024] Please see Figures 3-6The alternating component 4 includes two first support plates 41 disposed below the dissolution and recovery box 3. A first slide rail 42 is provided at the upper end of each first support plate 41. A first support frame 43 is connected to the upper end of the two first slide rails 42 via a slider. Two second support plates 44 are disposed between the two first support plates 41. A second slide rail 45 is provided at the upper end of each second support plate 44. A second support frame 46 is connected to the upper end of the two second slide rails 45 via a slider. A lifting frame 47 is disposed above the second support frame 46. The two dissolution and recovery boxes 3 are respectively disposed on the upper end of the first support frame 43 and the upper end of the lifting frame 47. A guide plate 48 is disposed between the two second support plates 44. A guide groove 49 is formed on the guide plate 48. The two ends of the guide groove 49 are horizontal, and the middle of the guide groove 49 is sunken. A fixed vertical plate 410 is provided on the lower end face of the lifting frame 47. A guide roller 411 is provided on the side wall of the fixed vertical plate 410 opposite to the guide plate 48. The guide roller 411 is slidably connected in the guide groove 49 on the guide plate 48. Guide rods 412 are provided at the four corners of the lower end face of the lifting frame 47. One end of the guide rod 412 passes through the second support frame 46. Two transmission wheels 413 are provided on a first support plate 41. A belt 414 is connected between the two transmission wheels 413. A first clamping plate 415 is provided on one side of the upper end face of the second support frame 46. A second clamping plate 416 is provided on the lower end face of the first support frame 43. The first clamping plate 415 and the second clamping plate 416 are clamped on the belt 414. The second clamping plate 416 is located above the first clamping plate 415. A drive motor 417 is provided on a first support plate 41. The drive motor 417 is connected to one transmission wheel 413.

[0025] It should be noted that the dissolving solution stored in the dissolution and recovery box 3 is a strong acid (such as sulfuric acid) or a strong alkali (such as sodium hydroxide).

[0026] In use, the waste lithium batteries placed inside the crushing box 1 are crushed. The crushed waste lithium batteries are then transported via conveyor belt 2 to a dissolution and recovery box 3 located below one end of conveyor belt 2. The dissolving liquid in the dissolution and recovery box 3 dissolves the metal scraps. When an appropriate amount of metal scraps is added to the dissolution and recovery box 3, the drive motor 417 is activated. The drive motor 417 drives the transmission wheel 413 connected to it to rotate. The transmission wheel 413 drives the belt 414 and another transmission wheel 413 to rotate. During rotation, the belt 414, through the first clamping plate 415 and the second clamping plate 416, respectively drives the second support frame 46 and the first support frame 43 to move in opposite directions. During movement, the second support frame 46 drives the fixed vertical plate 410 and the guide roller 411 on the fixed vertical plate 410 to move. The guide roller 411 moves along the guide groove 49 on the guide plate 48. When the guide roller 411 moves to the lower part of the guide groove 49, the guide plate 48 drives the lifting frame 47 to move down. When the guide roller 411 moves to the lowest point of the guide groove 49, the lifting frame 47 and the dissolution and recycling box 3 on the lifting frame 47 are at the lowest position in the stroke. When the dissolution and recycling box 3 on the lifting frame 47 intersects with the dissolution and recycling box 3 on the first support frame 43, the dissolution and recycling box 3 on the lifting frame 47 passes under the first support frame 43. When the first support frame 43 and the lifting frame 47 move to the end of the stroke, the lifting frame 47 returns to its original height under the guidance and push of the guide roller 411 and the fixed vertical plate 410. At this time, the first support frame 43 and the dissolution and recycling box 3 on the lifting frame 47 exchange positions. Then, the dissolution and recycling box 3 containing the debris is removed for metal extraction and storage, and replaced with the dissolution and recycling box 3 below one end of the conveyor belt 2 to continue recycling the crushed waste lithium batteries.

[0027] By setting up the alternating component 4, the two dissolution and recycling boxes 3 can be automatically switched in position. This avoids the problem of dissolving liquid splashing out when the crushed waste lithium batteries fall into the dissolution and recycling box 3, which could cause injury to the staff who are handling the dissolution and recycling box 3.

[0028] Please see Figure 2 A cleaning component 5 is provided on the lower end face of the conveyor belt 2. The cleaning component 5 includes two fixed rods 51 provided on the lower end face of the conveyor belt 2. A movable plate 52 is sleeved between the two fixed rods 51. A scraper 53 is provided on the upper end face of the movable plate 52. A limit block 55 is provided at the end of the fixed rod 51 away from the conveyor belt 2. A spiral spring 54 is provided on the limit block 55. The spiral spring 54 is sleeved on the fixed rod 51, and one end of the spiral spring 54 is connected to the movable plate 52. A receiving box 6 is provided below the movable plate 52. The receiving box 6 is located on the upper end face of the two second support plates 44.

[0029] The limiting block 55 and the spiral spring 54 are configured to provide elastic support force for the upward push of the moving plate 52. The moving plate 52 is used to place the scraper 53 on the lower end face of the conveyor belt 2, thereby cleaning the residue on the conveyor belt 2.

[0030] The shredded waste lithium battery residue falling on the conveyor belt 2 is adsorbed onto the conveyor belt 2. When the shredded waste lithium battery residue on the conveyor belt 2 passes the scraper 53 on the lower end face of the conveyor belt 2, the scraper 53 scrapes the residue off the conveyor belt 2 and it falls into the receiving box 6. In addition, during the intervals between the alternating positions of the two dissolution and recycling boxes 3, the shredded waste lithium batteries conveyed by the conveyor belt 2 will fall into the receiving box 6 for collection.

[0031] The cleaning component 5 is used to clean up the residue on the conveyor belt 2, thereby ensuring that the conveyor belt 2 is clean and tidy.
