Description

Liquid suction apparatus that effectively sucks liquid from a drum The present disclosure discloses a liquid suction device that effectively sucks liquid from a drum. More specifically, the liquid suction device of the present disclosure not only rapidly sucks liquid from inside the drum but also minimizes the amount of liquid remaining in the drum. Various chemicals are used in semiconductor manufacturing. Since the introduction of impurities into chemicals must be minimized during the semiconductor manufacturing process, chemicals are transported and used in drums after production. Conventionally, it was often the case that not all of the liquid inside the drum could be used. This is because if special treatment is performed to use all of the liquid, impurities may be introduced, which can lead to a significant increase in the defect rate of the semiconductor. In this regard, various attempts have been made to utilize not only the drum used in the semiconductor manufacturing process but also the liquid inside the container. For example, Korean Patent Application No. 10-2011-0135273 relates to an economical pump-type container. However, conventional inventions have the problem of being inefficient because their structure is very complex and even the shape of the drum must be changed. In addition, there is a disadvantage that the unit cost increases due to the production process, and there is a problem that its efficiency must be proven in order to be used in conservative semiconductor manufacturing.
