Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, in particular to a special high-efficiency disintegrator spraying device for lithium batteries. Background Art

[0002] Lithium battery is a widely used rechargeable battery, which is favored for its high energy density, long life and low self-discharge rate. When lithium battery needs to be disassembled for repair or replacement of internal components, various structural adhesives may be used to fix the lithium battery. These glues are difficult to remove by conventional methods. Therefore, debonding agent becomes an important auxiliary tool to help with non-destructive disassembly. The debonding agent is usually sprayed on the glue-coated area of the lithium battery to dissolve it.

[0003] Existing lithium battery dissolvers may produce some harmful gases during the colloid dissolving process, but the current spraying structure is only used in a ventilated and open environment to reduce the exhaust gas concentration, and most of them are not equipped with an exhaust gas adsorption structure. When the indoor air is not circulating or the dissolution operation is continuously sprayed, the exhaust gas is prone to accumulation, resulting in the harmful gases in the environment not being adsorbed and removed in time, causing their concentration to increase, affecting the health and safety of the operators.
