Description

Technical Field

[0001] The present invention belongs to the technical field related to lithium battery recycling, and more specifically, particularly relates to a resource recycling device based on intelligent waste lithium batteries. Background Art

[0002] Lithium, cobalt, nickel, etc. are key materials for manufacturing lithium batteries. These resources are unevenly distributed around the world and the cost of mining is increasing. Through resource recycling, these valuable metals in waste batteries can be re-extracted and used in new battery production, reducing dependence on primary mineral resources and achieving effective recycling of resources. However, the lithium battery recycling technology in the prior art has the following defects: In the existing technology, lithium battery recycling usually uses double-layer drums for crushing. Double-layer drum crushing often makes it difficult to accurately control the crushing particle size, which may produce too fine or too coarse materials, which has a direct impact on the efficiency of subsequent sorting steps (such as magnetic separation, air separation or screening). In addition, excessive crushing may damage valuable active materials and reduce the quality of recycling; In the prior art, lithium battery recycling uses double-layer drums for crushing, which is prone to poor crushing effect. Uneven crushing or excessive crushing may cause more electrolyte leakage inside the battery, increase the risk of harmful substances spreading, cause air and soil pollution, and are difficult to collect and treat. In the existing technology, lithium battery recycling adopts single crushing, which is easy to cause poor crushing effect. In addition, during the simple crushing process, harmful substances such as electrolyte and heavy metals in the battery may leak. Without proper collection and treatment measures, it is easy to cause soil and water pollution.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The resource recovery device based on intelligent waste lithium battery of the present invention adopts the feeding device and the rotating barrel device to achieve the double-layer crushing effect. This crushing effect can firstly perform preliminary physical compression on the battery, which is helpful to release the residual energy inside the battery before crushing, reduce the risk of short circuit and the possibility of thermal runaway, and improve the safety of the whole crushing process. The conical structure can gradually reduce the space when the material passes through. This design helps to more evenly control the particle size distribution of the material after crushing, avoid the generation of oversized or undersized fragments, and is conducive to the subsequent sorting and extraction process. The conical crushing column can guide the material to flow along its shape, reduce the invalid collision and mutual damage between the materials, and improve the crushing efficiency at the same time, because the material will naturally accelerate in the conical area, making the crushing process more efficient, and the double-layer design plus the conical structure can increase the passing speed of the material and reduce the occurrence of blockage, especially when processing a large number of waste lithium batteries, maintaining continuous and stable processing capacity, and such a design can also better utilize mechanical energy and reduce energy consumption. By accurately controlling the crushing force and material flow, energy consumption can be reduced while ensuring the crushing effect.

[0016] The resource recovery device based on intelligent waste lithium battery of the present invention adopts multi-layer crushing, which can gradually reduce the physical structural integrity of the battery. After each layer of crushing, the pressure inside the battery is gradually released, reducing the risk of fire caused by short circuit, improving the safety level of the entire recycling process, and through different levels of crushing steps, each level can adjust the crushing intensity and mode according to different crushing requirements, so as to more accurately control the particle size distribution of the final product. This is crucial for the subsequent separation and purification process, because the effective separation of different materials often depends on their particle size, and fine particle size control helps to improve the recovery efficiency of valuable metals such as lithium, cobalt, and nickel. Smaller and more uniform particles can be more fully exposed to chemical reagents, improve leaching efficiency, and thus improve the recycling rate of resources. Although multi-layer crushing may sound that the initial investment and operating costs are high, reasonable hierarchical design and power distribution can achieve more efficient energy utilization, reduce useless work, and help reduce overall energy consumption and operating costs in the long run.

[0017] The present invention discloses a resource recovery device based on intelligent waste lithium batteries, and the bottom is equipped with a grinding effect. This grinding effect can process the preliminarily crushed materials more carefully, effectively reduce the particle size, and fully expose the internal materials, thereby providing more favorable conditions for subsequent sorting and extraction. In addition, the fine and uniform powdered materials are more easily separated in the subsequent sorting process. In particular, for different materials that are closely mixed together, grinding can improve the physical differences between them, making it easier to use air separation, magnetic separation or flotation techniques for efficient separation. In addition, fine grinding helps to improve the recovery purity of valuable metals, because smaller particle size can increase the surface area of ​​chemical reactions, so that chemical reagents can more fully contact with target materials, thereby improving extraction efficiency and product quality. In addition, proper grinding can not only reduce the energy required for large pieces of materials to directly enter the fine processing stage, but also reduce the waste of materials caused by uneven crushing during the processing process, which is beneficial to saving energy and improving economic benefits in the long run.

[0035] Specific use of the present invention: When using the present invention, first move the present invention to the crushing workshop for installation. After the installation is completed, the power supply of the present invention can be connected, and when the power supply is connected, the conveyor belt is moved to the discharge port of the discharge box 52 provided at the support pile 12. Then, when the present invention is installed, the power supply can be started. After the startup is completed, the material inside the equipment body 14 is poured. When pouring, first ensure that the lithium battery can be crushed after being discharged by soaking in salt water. After ensuring that it is completed, the lithium battery can be poured from the inside of the feeding funnel 20. When the control system detects that the lithium battery is poured in, it controls the drive motor 54 set on the outer surface of the mounting plate 11. After the drive motor 54 is started, it will drive the rotating column 46 to rotate through the belt 47, and when the rotating column 46 rotates, it will drive the rotating gear plate 38 to rotate. When the rotating gear plate 38 rotates, it will drive the rotating center shaft 34 to rotate. When the rotating center shaft 34 rotates, it will drive the inner crushing rod 49 to rotate.

[0036] When the inner crushing rod 49 rotates, the rotating motor 28 arranged on the outer side of the fixed grinding barrel 37 will drive the rotating shaft 27 to rotate. When the rotating shaft 27 rotates, it will drive the gear column 25 to rotate. When the gear column 25 rotates, it will mesh with the gear ring 26 on the outer surface of the rolling barrel 24. When the rolling barrel 24 rotates, it will drive the oblique connecting plate 23 and the feeding funnel 20 to rotate. When the feeding funnel 20 rotates, it will drive the outer crushing rod 22 on the surface to rotate. When the outer crushing rod 22 rotates, it will form a reverse rotation with the inner crushing rod 49, so that the lithium batteries discharged will first be subjected to the crushing state formed by the outer crushing rod 22 and the inner crushing rod 49, and then be crushed. The crushed lithium batteries will fall onto the surface of the oblique grinding plate 31 through the gap between the inner crushing rod 49 and the outer crushing rod 22. After falling onto the surface of the oblique grinding plate 31, the lithium batteries will be crushed and screened again by the high-speed centrifugal force. When the crushed lithium batteries fall downward to the outer oblique mouth 35, they will be screened. If the size of the lithium batteries meets the gap of the outer oblique mouth 35, they will be discharged. If not, they will be rotated and ground and crushed again by the oblique grinding plate 31 on the surface of the conical barrel 32. When the lithium batteries are inside the side crushing chamber 33, they will be subjected to the high-speed grinding effect generated between the oblique grinding plate 31 and the wall of the rolling barrel 24 to further refine the material.

[0037] After the lithium battery is discharged from the outer inclined port 35, it will fall onto the surface of the grinding upper plate 43, and the lower scraper 42 provided on the lower surface of the lower end mounting plate 36 will clean the lithium battery on the surface of the grinding upper plate 43, and clean it to the surface of the grinding lower plate 44 through the grinding discharge port 45. Then, after the lithium battery falls onto the surface of the grinding lower plate 44, it will be rotated by the grinding upper plate 43 and finely ground with the lithium battery on the surface of the grinding lower plate 44. After the lithium battery is ground for one circle, it will be discharged into the discharge cavity 41 through the grinding discharge port 45. The lithium battery in the discharge cavity 41 will be passed through the conveyor belt for the next step of fine screening.
