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 for intelligent waste lithium batteries. Background Art

[0002] Lithium, cobalt, nickel, etc. are key materials for manufacturing lithium batteries. These resources are unevenly distributed globally and the mining costs are increasing day by day. Through resource recycling, these valuable metals in waste batteries can be re-extracted and used in the production of new batteries, reducing the dependence on primary mineral resources and achieving the effective recycling of resources. However, the lithium battery recycling in the prior art has the following defects:

[0003] In the prior art, the recycling of lithium batteries usually uses a double-layer drum for crushing. It is often difficult to precisely control the crushing particle size with double-layer drum crushing, and materials that are too fine or too coarse may be produced, which directly affects the efficiency of subsequent separation steps (such as magnetic separation, air separation or screening). In addition, excessive crushing may damage valuable active materials and reduce the recycling quality;

[0004] In the prior art, using a double-layer drum for crushing lithium batteries is prone to poor crushing effects. Uneven or excessive crushing may cause more leakage of the electrolyte inside the battery, increasing the risk of harmful substance diffusion, polluting the air and soil, and being difficult to collect and process;

[0005] In the prior art, single crushing is used for lithium battery recycling. This kind of crushing effect is prone to poor crushing, and during the simple crushing process, harmful substances such as the electrolyte and heavy metals in the battery may leak. Without proper collection and treatment measures, it is easy to cause soil and water source pollution.

[0013] Further technical solution, a plurality of outer crushing rods are arranged in an array on the bottom surface of the feeding funnel, the outer crushing rods are located outside the inner crushing rods, and a blanking plate is fixedly connected to the upper end of the outer crushing rods.

[0014] Further technical solution, a lower mounting plate is fixedly installed on the lower surface of the lower section of the rotating central shaft, a plurality of lower scraping plates are arranged on the lower surface of the lower mounting plate, grinding discharge ports are arranged on the surfaces of the grinding upper plate and the grinding lower plate, and a plurality of grinding plates are arranged in an array on the bottom surface of the grinding upper plate facing the grinding lower plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The resource recovery device for intelligent waste lithium batteries of the present invention adopts the provided feeding device and rotating barrel device to achieve a double-layer crushing effect. This crushing effect can first perform a preliminary physical compression on the battery, which helps to release the residual energy inside the battery before crushing, reduce the risk of short circuit and the possibility of thermal runaway, improve the safety of the entire crushing process, and 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 crushed material, avoid the generation of too large or too small fragments, and is beneficial to the subsequent sorting and extraction processes. Moreover, the conical crushing column can guide the material to flow along its shape, reduce the ineffective collision between materials and the mutual damage, and at the same time improve the crushing efficiency, 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 dealing with a large number of waste lithium batteries, it can maintain a continuous and stable processing capacity, and such a design can also better utilize mechanical energy and reduce energy consumption. By precisely controlling the crushing force and material flow, the energy consumption can be reduced while ensuring the crushing effect.

[0021] The resource recovery device for intelligent waste lithium batteries of the present invention adopts multi-layer crushing. This multi-layer crushing can gradually reduce the physical structure integrity of the battery. After each layer of crushing, the internal pressure of the battery is gradually released, reducing the risk of fire caused by short circuit and improving the safety level of the entire recovery process. And through different levels of crushing steps, the crushing intensity and method can be adjusted for different crushing requirements at each level, so as to more precisely 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 more fully contact chemical reagents, improving the leaching efficiency, thereby increasing the resource recovery rate. Although multi-layer crushing may sound like it has higher initial investment and operating costs, reasonable level design and power distribution can achieve more efficient energy utilization, reduce useless work, and help reduce the overall energy consumption and operating costs in the long run.

[0022] The resource recovery device for intelligent waste lithium batteries of the present invention is equipped with a grinding effect at the bottom. This grinding effect conducts more meticulous treatment on the preliminarily crushed materials, effectively reducing the particle size, exposing the internal materials fully, and providing more favorable conditions for subsequent sorting and extraction. Moreover, the small and uniform powdery materials are more easily separated effectively in the subsequent sorting process. Especially for those different materials that are closely mixed together, grinding can improve the physical differences between them, facilitating efficient separation using techniques such as air separation, magnetic separation, or flotation. And refined grinding helps to improve the recovery purity of valuable metals, because smaller particle sizes can increase the surface area of chemical reactions, enabling chemical reagents to more fully contact the target materials, thereby enhancing the extraction efficiency and product quality. And appropriate grinding not only reduces the energy required for large pieces of materials to directly enter the fine treatment stage, but also reduces material waste caused by uneven crushing during the treatment process, which is beneficial to saving energy and improving economic benefits in the long run.

[0050] Specific usage method of the present invention:

[0051] When using the present invention, first carry the present invention to the crushing workshop for installation. After the installation is completed, connect the power supply of the present invention. And when the power supply is connected, carry the conveyor belt to the discharge port of the discharge box 52 arranged at the support pile 12. Subsequently, after the present invention is installed, start the power supply. After starting, start to pour materials into the equipment body 14. When pouring materials, first ensure that the lithium battery can be broken only after being soaked in salt water for discharging. After ensuring, the lithium battery can be poured into the feeding funnel 20. When the control system detects that the lithium battery is poured in, the control system will drive the drive motor 54 arranged on the outer surface of the mounting plate 11. And after the drive motor 54 starts, 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 central shaft 34 to rotate. When the rotating central shaft 34 rotates, it will drive the inner crushing rod 49 to rotate.

[0052] And when the inner crushing rod 49 rotates, the rotating motor 28 arranged outside 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. And when the gear column 25 rotates, it will mesh with the gear ring 26 arranged on the outer surface of the rolling barrel 24. And when the rolling barrel 24 rotates, it will drive the inclined connecting plate 23 and the feeding funnel 20 to rotate. And when the feeding funnel 20 rotates, it will drive the outer crushing rod 22 arranged on the surface to rotate. And when the outer crushing rod 22 rotates, it will rotate in the opposite direction to the inner crushing rod 49, so that the incoming lithium battery will first be in the crushing state formed by the outer crushing rod 22 and the inner crushing rod 49. The crushed lithium battery will fall onto the surface of the inclined grinding plate 31 through the gap between the inner crushing rod 49 and the outer crushing rod 22. When the lithium battery falls onto the surface of the inclined grinding plate 31, it will be broken and screened again by the drive of high-speed centrifugal force. When the crushed lithium battery falls downward to the outer inclined opening 35, it will be screened. If the size of the lithium battery conforms to the gap of the outer inclined opening 35, it will be discharged. If not, the lithium battery will be rotated and ground again by the inclined grinding plate 31 arranged on the surface of the conical barrel 32. And when the lithium battery is inside the side crushing cavity 33, it will be further refined by the high-speed grinding effect generated between the inclined grinding plate 31 and the wall of the rolling barrel 24.

[0053] After the lithium battery is discharged from the outer inclined opening 35, it will fall onto the surface of the grinding upper plate 43. The lower scraping plate 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. Subsequently, when the lithium battery falls onto the surface of the grinding lower plate 44, it will be finely ground by the rotation of the grinding upper plate 43 and 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 interior of the discharge cavity 41 through the grinding discharge port 45. After the lithium battery is in the discharge cavity 41, it will be further refined and screened through the conveyor belt.

[0054] The resource recovery device for intelligent waste lithium batteries of the present invention adopts the provided feeding device and rotating barrel device to achieve a double-layer crushing effect. This crushing effect can first perform a preliminary physical compression on the battery, which helps to release the residual energy inside the battery before crushing, reduce the risk of short circuit and the possibility of thermal runaway, improve the safety of the entire crushing process, and 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 crushed material, avoid the generation of too large or too small fragments, and is beneficial to the subsequent sorting and extraction processes. Moreover, the conical crushing column can guide the material to flow along its shape, reduce the ineffective collision between materials and the mutual damage, and at the same time improve the crushing efficiency, because the material will naturally accelerate in the conical area, making the crushing process more efficient.

This multi-layer crushing can gradually reduce the physical structure 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 and improving the safety level of the entire recovery process. And through different levels of crushing steps, each level can adjust the crushing intensity and method according to different crushing requirements, so as to more precisely 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.

Although multi-layer crushing may sound like a higher initial investment and operating cost, a reasonable level design and power distribution can achieve more efficient energy utilization, reduce useless work, and help reduce the overall energy consumption and operating cost in the long run.

[0056] The bottom of a resource recovery device for intelligent waste lithium batteries according to the present invention is equipped with a grinding effect, which conducts more meticulous treatment on the preliminarily crushed materials, effectively reducing the particle size, fully exposing the internal materials, providing more favorable conditions for subsequent sorting and extraction. Moreover, the fine and uniform powdery materials are more easily and effectively separated in the subsequent sorting process.
