[0033] The specific settings and functions of the cleaning device 5 and the storage device 6 will be described in detail below.

[0034] like Figure 1-Figure 4As shown, the cleaning device 5 includes a collection box 501, which is fixedly connected to the lower surface of the frame 1, and a scraper 508 is fixedly connected to the inner wall of the collection box 501, and a roller brush 509 is rotatably connected to the inner wall of the frame 1. By setting the scraper 508, the battery powder adhering to the surface of the conveyor belt 2 can be scraped off as much as possible, and by setting the roller brush 509, the conveyor belt 2 can be further cleaned, so as to avoid the battery powder adhering to the conveyor belt 2 as much as possible. By setting the collection box 501, the battery powder can be collected. Two connecting rods 502 are fixedly connected to the upper surface of the collection box 501, and the other ends of the two connecting rods 502 are fixedly connected to the frame 1. The side of the collection box 501 close to the driving motor 4 is fixedly connected to an electric telescopic rod 503, and the surface of the electric telescopic rod 503 is covered with a stabilizing plate 504, and the end of the stabilizing plate 504 away from the electric telescopic rod 503 is fixedly connected to the collection box 501. The connection rod 502 can be provided to improve the installation stability of the collection box 501, and the stabilizing plate 504 can be provided to increase the stability of the electric telescopic rod 503 when it is extended or retracted.

[0035] The output end of the electric telescopic rod 503 is fixedly connected with a push plate 505, and the push plate 505 is slidably connected to the inner wall of the collection box 501. The side of the push plate 505 away from the electric telescopic rod 503 is fixedly connected with two push rods 506, and the other ends of the two push rods 506 are fixedly connected with a sealing plate 507, and the sealing plate 507 is slidably connected to the inner wall of the collection box 501. The electric telescopic rod 503 can drive the push plate 505 to move, and the push rod 506 can connect the push plate 505 and the sealing plate 507, so that the movement of the push plate 505 can drive the movement of the sealing plate 507.

By setting the sensor 511, a sensing signal can be sent out after the support plate 510 moves close to the sensor 511.

[0036] like Figure 3 and Figure 4 as well as Figure 5-Figure 7As shown, the storage device 6 includes a fixed rotating rod 62, which is rotatably connected to the inner wall of the collection box 501, a telescopic plate 63 is fixedly connected to the surface of the fixed rotating rod 62, and a moving rod 64 is fixedly connected to the other end of the telescopic plate 63. Two arc grooves 61 are provided on the inner wall of the collection box 501, and the moving rod 64 is slidably connected to the surface of the arc groove 61 on the collection box 501. The telescopic plate 63 can be controlled to expand or contract by setting the fixed rotating rod 62 and the moving rod 64, so that the telescopic plate 63 can be used to temporarily collect battery powder. By setting the moving rod 64 and the arc groove 61, the moving rod 64 can be connected to the collection box 501 while ensuring that the moving rod 64 can move.

[0037] The surface of the moving rod 64 is rotatably connected with a sliding rod 67, the surface of the sliding rod 67 is covered with a sleeve rod 66, one end of the sleeve rod 66 away from the sliding rod 67 is fixedly connected with a mounting plate 65, and one side of the mounting plate 65 is fixedly connected to the collection box 501. By providing the mounting plate 65, the sleeve rod 66 and the sliding rod 67 can be connected to the collection box 501, the sliding rod 67 slidably connected to the inner wall of the sleeve rod 66 can move, and the sliding rod 67 rotatably connected to the surface of the moving rod 64 will not limit the rotation of the moving rod 64. The end of the sliding rod 67 away from the moving rod 64 is fixedly connected with a second spring 68, and the other end of the second spring 68 is fixedly connected to the sleeve rod 66. The second spring 68 ensures that the sliding rod 67 is stably connected to the sleeve rod 66, and the position of the sliding rod 67 can be limited. At the same time, the second spring 68 can play a guiding role when the sliding rod 67 is retracted.

[0038] Working principle: when using the feeding device of the waste lithium battery pyrolysis kiln to feed the waste lithium batteries, first connect the feeding device of the waste lithium battery pyrolysis kiln to the external power supply, then start the driving motor 4 to drive the conveyor belt 2 to rotate, and then put the waste lithium batteries on the conveyor belt 2. At this time, the waste lithium batteries are driven by the conveyor belt 2 and the blocking plate 3 and gradually approach the pyrolysis kiln to complete the feeding process of the waste lithium batteries. By setting the frame 1, the feeding device of the waste lithium battery pyrolysis kiln can be installed next to the pyrolysis kiln. When using the feeding device of the waste lithium battery pyrolysis kiln for feeding, after the conveyor belt 2 and the blocking plate 3 drive the waste lithium batteries into the pyrolysis kiln, the conveyor belt 2 continues to rotate. At this time, the scraper 508 scrapes the surface of the conveyor belt 2, so that the battery powder on the surface of the conveyor belt 2 falls into the collection box 501, and then the conveyor belt 2 passes through the roller brush 509. Under the action of the roller brush 509, the surface of the conveyor belt 2 is further cleaned. As the battery powder in the collection box 501 is gradually collected, the battery powder squeezes the support plate 510, causing the first spring 512 to contract. At this time, the support plate 510 is close to the sensor 511, and the sensor 511 controls the electric telescopic rod 503 to start. The electric telescopic rod 503 pushes the push plate 505 to push the battery powder to move on the surface of the support plate 510. At the same time, the push plate 505 pushes the sealing plate 507 through the push rod 506 to open the collection The push plate 505 pushes most of the battery powder into the pyrolysis kiln, and the electric telescopic rod 503 drives the push plate 505 to return to its original position. At this time, under the action of the elastic force of the first spring 512, the push plate 505 moves close to the roller brush 509, and the connecting rod 502 can increase the stability of the installation of the collection box 501. By setting the push plate 505, the battery powder collected in the collection box 501 can be pushed into the pyrolysis kiln as much as possible. By setting the stabilizing plate 504, the stability of the electric telescopic rod 503 during extension and retraction is improved. By setting the cleaning device 5, the conveyor belt 2 can be cleaned as much as possible after the waste lithium batteries are transported by the conveyor belt 2, and the battery powder can be avoided as much as possible from remaining on the conveyor belt 2. At the same time, the collected battery powder can be pushed into the pyrolysis kiln, which further facilitates the recycling of waste lithium batteries.

[0039] In the process of the push plate 505 pushing the battery powder on the surface of the support plate 510 into the pyrolysis kiln, the movement of the push plate 505 can drive the mounting plate 65 to move synchronously, thereby driving the sleeve rod 66 to move close to the scraper 508. At this time, the slide rod 67 slides on the inner wall of the sleeve rod 66 while rotating on the surface of the moving rod 64, thereby driving the telescopic plate 63 to unfold. The movement of the sleeve rod 66 can drive the moving rod 64 to move on the surface of the arc groove 61 on the collection box 501 through the slide rod 67, thereby driving the fixed rotating rod 62 in the collection box. The inner wall of 501 rotates, and when the push plate 505 moves close to the stabilizing plate 504, under the action of the elastic force of the second spring 68, the slide bar 67 moves away from the roller brush 509, and at the same time the slide bar 67 rotates on the surface of the moving rod 64, thereby driving the telescopic plate 63 to contract. By setting up the storage device 6, when the push plate 505 pushes the battery powder collected in the collection box 501 into the pyrolysis kiln, the battery powder scraped from the conveyor belt 2 can be temporarily stored, thereby avoiding the battery powder from scattering as much as possible.
