Technical Field
[0001] This utility model relates to the field of battery recycling technology, specifically to an environmentally friendly recycling and processing device for waste lithium batteries. Background Technology
[0002] Used lithium batteries refer to lithium-ion batteries that have lost their usability and are mainly divided into power batteries and consumer electronics batteries. Power batteries are typically used in transportation equipment such as automobiles, electric vehicles, and hybrid vehicles, and have high capacity and energy density; while consumer electronics batteries are used in electronic devices such as mobile phones, cameras, and laptops, and are usually in a small form.

During retrieval, the battery can be removed manually by simply opening the latch, significantly reducing human contact with the battery during processing and improving retrieval efficiency. This enables unmanned and highly efficient soaking treatment of waste lithium batteries. Attached Figure Description

[0020] Please see Figure 1-4 This utility model provides a technical solution: an environmentally friendly waste lithium battery recycling and processing equipment, including an immersion tank 1 and an iron mesh trough 5. Two pairs of support columns 2 are installed on the upper end of the immersion tank 1, and a fixing frame 3 is installed on the two pairs of support columns 2. A first box 4 located between a pair of support columns 2 is installed between the fixing frame 3 and the upper wall of the immersion tank 1.

[0021] The auxiliary stirring mechanism includes a third box 20 located inside the second box 15. The front end of the third box 20 is hinged to the upper end of the second box 15, and the rear end is a free end. A second motor 22 is installed on the inner wall of the third box 20. A connecting rod 26 is installed on the driving end of the second motor 22.

The stirring rod 19 reciprocates and stirs the waste lithium batteries inside the iron mesh tank 5, so that the lithium batteries are fully soaked in salt water. After soaking for forty-eight hours, the iron mesh tank 5 is raised by reversing the first motor 9. After the salt water is drained, the iron mesh plate 17 is opened by manually opening the latch 16. The iron mesh plate 17 moves to the upper end of the discharge tank 7. At this time, the electric hydraulic cylinder 21 inside the second box 15 is activated. With the assistance of the slider 27, the third box 20 is swung, thereby completing the tilting of the batteries inside the third box 20, thus completing the tilting of the lithium batteries.

[0023] The second motor 22 and the connecting rod 26 work together to link two pairs of incomplete gears 23 and rack 25, thereby enabling the rectangular frame 24 to move inside the chute of the third box 20, and thus enabling the stirring rod 19 to reciprocate and stir the waste lithium batteries inside the iron mesh trough 5.
[0024] In this embodiment, the auxiliary tilting mechanism includes an electric hydraulic cylinder 21, which is installed inside the second housing 15. The upper wall of the second housing 15 has a through hole for the extension and retraction of the drive end of the electric hydraulic cylinder 21. A slider 27 is hinged to the upper wall of the drive end of the electric hydraulic cylinder 21. The lower wall of the third housing 20 has a second sliding groove for the slider 27 to be installed.
[0025] In this embodiment, the side wall of the wire mesh trough 5 is provided with a second rectangular through hole, and the lower wall inside the second rectangular through hole is hinged with a wire mesh plate 17. The upper end of the wire mesh plate 17 is fixed to the wire mesh trough 5 by a pin 16.

[0026] The electric hydraulic cylinder 21 inside the second housing 15 is activated, and the third housing 20 is swung with the assistance of the slider 27, thereby tilting the battery inside the third housing 20 and thus tilting the lithium battery.
[0027] In this embodiment, the lifting drive mechanism includes a first motor 9 fixedly installed inside the first housing 4. A threaded rod 10 is installed on the drive end of the first motor 9. The end of the threaded rod 10 away from the drive end of the first motor 9 is screwed onto the inner side wall of the first housing 4. A pair of second slide rails 11 are installed inside the first housing 4. A threaded sleeve 12 is threaded onto the threaded rod 10. A connecting plate 13 is installed on the threaded sleeve 12 and the pair of second slide rails 11. A connecting block 14 is installed on the side wall of the connecting plate 13. A third rectangular through hole is opened on the side wall of the first housing 4 for the connecting block 14 to move. The end of the connecting block 14 away from the connecting plate 13 is installed on the side wall of the wire mesh trough 5.
[0028] The first motor 9 drives the threaded rod 10 to move in conjunction with the threaded sleeve 12, and the connecting block 14 moves the iron mesh trough 5 with the assistance of a pair of second slide rails 11. At this time, the iron mesh trough 5 can move smoothly through the first slide rail 6 on the support column 2.
[0029] In this embodiment, the soaking tank 1 is further configured such that a discharge trough 7 is installed on the wall surface near the lower end of the iron mesh plate 17, and a liquid outlet 8 is opened on the side wall surface of the soaking tank 1.
[0030] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.
[0031] Example: When processing waste lithium batteries, it is necessary to soak them in salt water to conduct electrical discharge. However, the electrolyte generated during the process is harmful to human health, and manual retrieval and handling are required after soaking, which poses a risk. Therefore, a soaking device that does not require manual retrieval and handling has been designed.
[0032] At this point, the waste lithium batteries are poured into the wire mesh trough 5, and brine is injected into the soaking tank 1. The first motor 9 inside the first tank 4 is then activated. The first motor 9 drives the threaded rod 10 and threaded sleeve 12, which, with the assistance of a pair of second slide rails 11, moves the wire mesh trough 5 via the connecting block 14. The wire mesh trough 5 can then move smoothly along the first slide rail 6 on the support column 2. After moving into the soaking tank 1, the second motor 22 is activated. The second motor 22, in conjunction with the connecting rod 26, drives two pairs of incomplete gears 23 and racks 25, thereby enabling the rectangular frame 24 to move within the trough of the third tank 20. The stirring rod 19 moves back and forth to stir the waste lithium batteries inside the iron mesh tank 5, so that the lithium batteries are fully soaked in salt water. After soaking for forty-eight hours, the iron mesh tank 5 is raised by reversing the first motor 9. After the salt water is drained, the iron mesh plate 17 is opened by manually opening the latch 16. At this time, the iron mesh plate 17 moves to the upper end of the discharge tank 7. Then, the electric hydraulic cylinder 21 inside the second box 15 is activated. With the assistance of the slider 27, the third box 20 is swung to complete the tilting of the batteries inside the third box 20, thus completing the tilting of the lithium batteries. The liquid inside the soaking tank 1 can be discharged and cleaned by opening the liquid outlet 8.
[0033] This equipment employs mechanical operation for both battery soaking and battery retrieval. Compared to existing soaking equipment, it allows for full-area contact between the battery and brine during the soaking process. During retrieval, the battery can be removed manually by simply opening pin 16, significantly reducing manual contact with the battery during processing and improving retrieval efficiency. This enables unmanned and highly efficient soaking treatment of waste lithium batteries.
