| titleOfInvention | System for drying separation film of lithium secondary battery |
| abstract | The present invention relates to a lithium secondary battery separator film drying system that recovers MC solvent remaining on the surface of a separator in an extraction process of removing oil on the surface of a separator while drying the separator during a separator production process of a lithium secondary battery. To this end, in the lithium secondary battery separator film drying system, after the extraction process, the separator film is firstly heated through a plurality of preheating rollers disposed inside the preheating chamber, and the MC solvent on the surface of the separator film is firstly removed through the solvent removal means. a preheating unit, a drying unit in which the separation membrane film, which is heated first in the preheating unit, passes through a plurality of drying rollers disposed inside the drying chamber, and secondarily removes the MC solvent remaining on the surface in a secondly heated state, the drying unit A cooling unit in which the temperature-raised separator film is cooled to room temperature while passing through a plurality of cooling rollers disposed inside the cooling chamber, disposed between the drying chamber and the cooling chamber, and in the process of entering and discharging the separator film It includes a connection chamber that blocks the inflow of outside air through a sealing unit in which air pockets are formed in multiple stages. |
