Abstract

본 발명은 드라이룸 장치에 관한 것으로, 일반적으로 스파이럴 리튬 밧데리는 그 제조 특성상 제조환경을 상대습도2% 이내로 유지해야 하는 까닭에 상기 상대습도를 2% 이내로 유지하여 운용되는 드라이룸 내부에서 제조를 한다. 종래에는 이러한 드라이룸을 운영함에 있어서, 드라이룸 내부를 대기중의 공기로 채워지게 하므로서 드라이룸 내부에서 제조중인 밧데리 및 부품 등의 재질상 특성을 인한 공기와의 화학작용에 의해 산화나 부식등이 발생하여 불량품을 발생시키는 문제점을 해소하기 위해, 드라이룸의 천정 부분에 가스 공급관과 가스분사기 및 리턴 덕트를 설치하고 제어기를 통하여 불활성 가스의 공급량을 제억되게 하므로써 드라이룸 내부에서 제조중인 밧데리 및 부품 등의 재질상 특성으로 인한 공기와의 화학작용에 의해 산화나 부식등을 방지하게 하는 효과가 있다.The present invention relates to a dry room apparatus, and in general, a spiral lithium battery is manufactured in a dry room operated by maintaining the relative humidity within 2% because the manufacturing environment should be maintained within 2% of relative humidity. . Conventionally, in operating such a dry room, the inside of the dry room is filled with air in the air, and oxidation or corrosion is caused by chemical reaction with the air due to the material characteristics of the battery and parts manufactured in the dry room. In order to solve the problem of defective products, the gas supply pipe, gas injector and return duct are installed on the ceiling part of the dry room, and the amount of inert gas supplied through the controller is stored so that the batteries and parts in the dry room are manufactured. It has the effect of preventing oxidation or corrosion by chemical action with air due to the material's properties.
