본 발명은 선박 탱크의 침전방지장치에 관한 것이다. 더욱 상세하게는 탱크 형태를 원형 탱크 혹은 챔버 탱크로 구성함으로써 탱크 내의 침전을 방지하고 순환 효율을 높일 수 있는 선박 탱크의 침전방지장치에 관한 것이다. The present invention relates to an apparatus for preventing precipitation of a marine tank. More specifically, the present invention relates to a sedimentation prevention device of a ship tank, which can prevent the settling in a tank and improve circulation efficiency by configuring a tank type as a circular tank or a chamber tank.

일반적으로, 선박은 각종 액체나 고체, 액체 혼합물을 저장하기 위한 다수의 탱크(tank)를 구비하고 있다. 이러한 탱크(tank)에는 탱크 내의 액체 혹은 고체, 액체 혼합물이 순환되지 않아 침전물이 생겨서 침전물을 따로 처리해야 하는 문제가 발생한다.Generally, ships have a number of tanks for storing various liquids, solids and liquid mixtures. In such a tank (tank) there is a problem that the sediment is generated because the liquid or solid, liquid mixture in the tank is not circulated, so that the sediment must be treated separately.

그 중에서 워터 발라스트탱크(Water Ballast Tank), 리퀴드 머드탱크(Liquid Mud Tank) 등 탱크 내부의 침전물 때문에 침전물 수거 비용 및 설계 변경 등 추가 비용이 많이 발생하고 있다. Among them, the sediment inside the tank, such as the water ballast tank and the liquid mud tank, causes additional costs such as sediment collection costs and design changes.

따라서 선박 탱크 내에 침전을 방지하고 탱크 내의 순환을 용이하게 하는 장치가 필요하다. 이러한 탱크침전 방지장치를 구비하고 있는 선박에 있어서 탱크 형태를 변화시켜 주게 되면 순환 효율이 증가한다.Therefore, there is a need for a device that prevents settling in a vessel and facilitates circulation in the tank. In a ship provided with such a tank sedimentation preventing device, the circulation efficiency increases when the tank shape is changed.

이에 본 발명은 상기한 문제점을 해결하기 위한 것으로서 본 발명의 목적은 탱크 형태를 원형 탱크 혹은 챔버 탱크로 구성함으로써 탱크 내의 침전을 방지함과 더불어 순환 효율이 높일 수 있는 선박 탱크의 침전방지장치를 제공하는 데 있다.
