The present invention relates to an apparatus to prevent backflow of a ship fluid tank, and more specifically, relates to an apparatus to prevent backflow of a ship fluid tank to be able to prevent an oil component separated from water component from flowing backwards in a fluid tank. For this purpose, provided is the apparatus of preventing backflow of a ship fluid tank which is mounted on a fluid tank for a ship to be able to prevent oil from backflow. The apparatus comprises: a partition wall to partition an interior of the fluid tank; a cylindrical supporting rod formed to protrude to an upper side of the partition wall in a longitudinal direction; and a backflow preventing member to prevent a backflow of fluid installed in the outer peripheral surface of the supporting rod to be rotated.
본 발명은 선박용 유체탱크 역류방지장치에 관한 것으로, 더욱 상세하게는 유체탱크 내에 물 성분과 분리된 원유성분의 역류를 방지할 수 있는 유체탱크 역류방지장치에 관한 것이며, 이를 위하여 본 발명은 선박용 유체탱크에 설치되어 오일의 역류를 방지하는 선박용 유체탱크 역류방지장치에 있어서, 유체탱크의 내부를 구획하는 격벽; 격벽의 길이방향으로 상부에 돌출 형성되는 원기둥 형상의 지지봉; 및 지지봉의 외주면에서 선회 가능하게 설치되어 유체의 역류를 방지하는 역류방지부재;를 포함하는 선박용 유체탱크 역류방지장치를 제공한다.
