Description

Technical Field

[0001] This invention relates to the field of battery electrode recycling technology, specifically to a waste battery electrode repair and regeneration powder stripping and sorting equipment. Background Technology

[0002] With the popularization and technological development of electric vehicles, the recycling and reuse of used batteries has gradually become an urgent environmental and resource issue that needs to be addressed. The power batteries in electric vehicles, especially lithium batteries, will eventually be decommissioned after a period of use. The positive and negative electrode plates of these batteries contain a large amount of valuable metal materials and rare resources, such as lithium iron phosphate, ternary materials, and graphite. The recycling and regeneration of these resources is of great significance for reducing environmental pollution and promoting resource recycling.

[0003] Currently, the dismantling and recycling process of waste batteries mainly involves separating the positive and negative electrode sheets and recovering valuable materials such as aluminum, copper, graphite, lithium iron phosphate, and ternary materials. However, existing waste battery positive electrode sheet recycling equipment faces several technical challenges. First, traditional equipment is typically complex in structure, inconvenient to operate, and requires a considerable amount of time to complete material separation and recycling. Second, existing equipment struggles to efficiently recover graphite powder, a crucial component of battery negative electrode materials; its low recycling and processing efficiency leads to a significant waste of graphite resources. Furthermore, existing equipment cannot adequately guarantee material separation during crushing and sorting processes, resulting in low recovery rates that fail to meet market demand for recycled resources.

[0004] Currently, common waste battery recycling technologies mainly rely on mechanical crushing, wet sorting, or dry stripping. However, these methods often suffer from incomplete sorting, low resource recovery rates, and high energy consumption. In particular, existing equipment cannot effectively separate different substances when sorting graphite and metal materials in battery electrodes, resulting in incomplete resource recovery and affecting the economic and environmental benefits of the entire recycling process.

[0005] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a stripping and sorting equipment for the regeneration of waste battery electrode sheets. Summary of the Invention

[0033] The features and exemplary embodiments of various aspects of the present invention will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be practiced without some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present invention by illustrating examples of the invention.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present invention provides a technical solution for a waste battery electrode repair and regeneration powder stripping and sorting device: it includes a base frame 1, on which a motor base 11, an adjustment groove 12, and an adjustment seat 13 are provided. The base frame 1 provides a stable support structure for the entire device.

[0035] Crushing mechanism such as Figure 3As shown, the device, mounted on the base frame 1, includes a lower crushing shell 21, an upper crushing shell 22, and connecting elements such as an arc-shaped seat 23, an arc-shaped limiting support 24, an upper shell handle 25, a T-block 27, a threaded portion 271, and a nut 28. The upper crushing shell 22 has a feed hopper 26 on its top side for feeding waste battery electrodes into the crushing mechanism. The upper crushing shell 22 and the lower crushing shell 21 are connected by a hinge for easy opening and cleaning. The arc-shaped limiting support 24 is mounted on the lower crushing shell 21 to limit the position of the arc-shaped seat 23. The lower crushing shell 21 and the upper crushing shell 22 are fixed together by an upper shell locking seat 29, a T-block 27, and a threaded portion 271, ensuring the stability and durability of the crushing mechanism.

[0036] Crushing drive components such as Figure 3 As shown, the device includes a motor 31, a main pulley 32, an auxiliary pulley 33, a pulley protective housing 34, and a crushing shaft 35 that passes through the crushing mechanism. The crushing shaft 35 is supported by a bearing seat 36 to ensure stable rotation. The motor 31 drives the main pulley 32, and the transmission between the main pulley 32 and the auxiliary pulley 33 is achieved through a belt, driving the crushing shaft 35 to rotate. The pulley protective housing 34 covers the transmission components to prevent dust and debris from entering, ensuring the normal operation of the equipment.

[0037] Crushing execution unit such as Figure 3 As shown, the device fixed to the crushing shaft 35 includes a crushing disc 37, a crushing arm 38, and crushing teeth 39 located at the end of the crushing arm 38. The surface of the crushing teeth 39 is provided with serrated protrusions for quickly crushing battery electrodes and improving crushing efficiency.

[0038] Sorting organizations such as Figure 7 As shown, the structure, connected to the outlet of the crushing lower shell 21, includes a shaft-end impeller 41, a crushing discharge hopper 42, a sorting channel 43, a fan 44, a conveying channel 45, an induced draft fan 46, a powder pipe 47, a cyclone separator 48, a powder outlet 49, a dust collector 50, and a separator mounting frame 51. The airflow generated by the induced draft fan 46 flows sequentially through the fan hood 44, the conveying channel 45, and the powder pipe 47 into the cyclone separator 48. The separated powder is output from the powder outlet 49, and the exhaust gas is purified by the dust collector 50 before being discharged.

[0039] Particle collection box 6 Figure 7 As shown, it is located at the bottom of the sorting channel 43 and is connected to it. The sorting channel 43 is equipped with a turbulence column 61 and a particle separation filter 62. The turbulence column 61 and the particle separation filter 62 are arranged at an angle to guide different particles to the particle collection box 6 for collection, thereby improving the recycling rate of resources.

[0040] With the above structure, the waste battery electrode repair and regeneration powder stripping and sorting equipment of the present invention can effectively crush waste battery electrodes and efficiently separate valuable metallic and non-metallic materials, such as aluminum, copper, graphite, lithium iron phosphate, and ternary materials, through a sorting mechanism. The equipment has a simple structure, is easy to operate, and can meet the processing needs of battery electrodes of different specifications, possessing high practical value and economic benefits.

[0041] The working principle and usage process of this invention are as follows: Waste battery electrode sheets are fed into the crushing mechanism through the feed hopper 26. The motor 31 is started, driving the main pulley 32 to rotate, which in turn drives the auxiliary pulley 33 to rotate via a belt, thereby driving the crushing shaft 35 to rotate. The crushing execution unit on the crushing shaft 35 rotates accordingly, using the serrated protrusions on the crushing teeth 39 to quickly crush the battery electrode sheets. The crushed material enters the sorting mechanism through the outlet of the crushing lower shell 21. In the sorting mechanism, the airflow generated by the blower 46 and the end shaft impeller 41 blows the material up and enters the cyclone separator 48 through the wind hood 44, the conveying channel 45, and the powder pipe 47. In the cyclone separator 48, the powder is separated and output through the powder outlet 49, while the exhaust gas is purified by the dust collector before being discharged. At the same time, the particle collection box 6 set at the bottom of the sorting channel 43 can collect battery electrode sheet fragments of different particle sizes. Through the guiding effect of the turbulence column 61 and the particle separation filter 62, the recycling rate of resources is improved. The entire process is efficient and environmentally friendly, effectively enabling the repair, regeneration, and resource utilization of waste battery electrodes.
