Patent ID: 10396408

Abstract:
The present invention relates to a waste battery treatment apparatus using continuous heat treatment, and a method for recovering valuable metals from lithium-based batteries using the same, the waste battery treatment apparatus comprising: a frame (10); a reaction reservoir (30) which is disposed in the inner space of the frame (10) and has thereinside a treatment space (S1) in which waste batteries to be treated are disposed; an inlet 34 (33) in which a gas blocking door (34) is disposed so as to selectively communicate the treating space (S1) with the outside, and which serves as a path through which an object to be treated is inputted to the treating space (S1) of the reaction reservoir (30). In addition, the waste battery treatment apparatus is provided with a vacuum forming means (40) which is connected to the treatment space (S1) of the reaction reservoir (30) to vacuumize the treatment space (S1). In the treatment apparatus of the present invention, since the inside of the reaction reservoir (30) is vacuumized and, at the same time, an inert gas is injected thereinto while a pretreatment process of waste batteries is performed in the reaction reservoir (30), the waste batteries are prevented from exploding during heat treatment, whereby work stability can be improved.
