Problems solved by technology

[0004] In the prior art, the method of incineration is used to recycle waste lithium batteries into cement. Although this method can quickly decompose lithium batteries, branch combustion is easy to cause pollution, and when branch combustion, the components that can be reused The efficiency of recycling is also not reflected

Embodiment Construction

[0036] The invention will now be further described in detail in conjunction with the accompanying drawings and embodiments. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so it only shows the configuration related to the invention.

[0037] It should be noted that if there is a directional indication (such as up, down, bottom, top, etc.) in the embodiment of the present invention, the directional indication is only used to explain the relative positional relationship between the components in a certain posture, Sports conditions, etc., if the specific posture changes, the directional indication will also change accordingly. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of indicated technical features. Thus, a feature defined as "first" and "second" may...

Abstract

The invention provides a lithium battery recovery process. The lithium battery recovery process comprises the following steps: S1, feeding: arranging a lithium battery; S2, tearing and crushing, namely crushing the cleaned lithium battery; S3, preliminary sorting: separating a diaphragm from the lithium battery crushed aggregates; S4, magnetic separation conveying: separating the tabs from the lithium battery crushed aggregates; S5, multi-stage crushing, grinding, refining and sorting: carrying out multi-stage crushing, grinding, refining and sorting on the lithium battery crushed aggregates to obtain recyclable materials; and S6, jigging sorting, namely conducting jigging sorting on the ground and sorted lithium battery crushed aggregates, and separating the remaining recyclable materials. The invention discloses an environment-friendly lithium battery recovery process which is convenient to operate and high in recycling efficiency.

Description

technical field [0001] The invention relates to the field of industrial equipment, in particular to a lithium battery recycling process. Background technique [0002] After lithium batteries are decommissioned, they are usually reused in stages. For example, some of the used lithium batteries of electric vehicles are damaged or the capacity decay exceeds the national standard. The car factory recycles them, and then decomposes them into monomers, then screens them for capacity and internal resistance, and reassembles them into PACKs. Finally, ternary lithium batteries will be used in electric vehicles, logistics vehicles and other markets. When the battery decays again, it can be used in street lamps and other occasions that do not require high internal resistance. When the cascade utilization is over, the battery will be recycled again, and metal copper, aluminum, and lithium will be recycled after crushing for battery production and recycling. [0003] The lithium battery...
