Problems solved by technology

[0003] The recovery of the electrolyte in waste lithium-ion batteries is difficult and costly, and has no recycling value in the industry. How to deal with pollution is a problem that must be solved in the industry
At the same time, due to the strong viscosity of the added binder, the broken electrode material is bonded to the current collector. If the binder is not treated, it is not conducive to the sorting and recovery of later materials.

Abstract

The invention discloses a pyrolysis device for organic matter in crushed materials after crushing of waste lithium ion batteries. The pyrolysis device comprises a combustion chamber and a furnace body with a hearth. The hearth is provided with a feeding port, a discharging port and a flue gas outlet. The combustion chamber is connected with a combustion assembly used for generating hot air in thecombustion chamber, and the hearth communicates with the combustion chamber. The pyrolysis device has the beneficial effects of being high in environment friendliness and good in pyrolysis efficiency, pyrolysis evenness and pyrolysis sufficiency.

Description

technical field [0001] The invention relates to the technical field of recycling and processing equipment for waste batteries, in particular to equipment for pyrolyzing organic matter in scraps of broken waste lithium-ion batteries. Background technique [0002] The organic impurities in the electrode material after the lithium-ion battery is broken are mainly the electrolyte, binder and separator added during the battery manufacturing process. The role of the battery electrolyte is to achieve ion conduction, the common electrolyte is DMC (dimethyl carbonate) + LiPF 6 (lithium hexafluorophosphate). The addition of the binder is to ensure the uniformity and safety of the material during pulping, to play a bonding role between the active material particles, to bind the active material to the current collector, and to facilitate the formation of an SEI film on the surface of the carbon material ; Commonly used binders are: polyvinyl alcohol (PVA), polytetrafluoroethylene (PTF...
