Description

Technical Field

[0001] The utility model relates to the field of battery recycling, in particular to a device for calcining, screening and recycling waste battery powder. Background Art

[0002] Lithium-ion batteries have been widely used in various fields of electronic products. As lithium batteries are used for a longer time and become damaged, their service life is reduced. Used batteries need to be recycled. Usually, the batteries need to be crushed first to obtain battery powder, and then the metal elements in the batteries are recovered through chemical reactions and calcination.

[0003] During the battery crushing process, impurities will be mixed into the battery powder. Before the battery powder is calcined, the powder needs to be screened to remove large particles of impurities. The crushed battery powder is added to the screening recovery device for screening. When the battery powder is added to the screening device from the feed port, as the powder falls downward, the feeding process will cause the battery powder to float, small particles of powder will escape into the air, and the chemical substances in the powder will pollute the air, causing damage to people's health.
