The present invention relates to a filtering device for ballast water of a ship and, more specifically, to a filtering device for ballast water of a ship, comprising: a base plate; an outer screen which is formed in the shape of a hollow body mounted on the upper surface of the base plate and through which a fluid comes in and out of a side surface thereof; an inner screen which is mounted on the outer screen, is formed in the same shape as the shape of the outer screen, and has a diameter shorter than the diameter of the outer screen; a plurality of elastic balls loaded in a space between the outer screen and the inner screen and made of an elastic material; a compression ring mounted between the outer screen and the inner screen; and a compressing means for compressing or releasing the elastic balls by driving the compression ring to linearly reciprocate between the outer screen and the inner screen. Therefore, the filtering device for ballast water of a ship according to the present invention can process a greater number of microorganisms for a unit time than a traditional two-dimensional screen, has operating efficiency enhanced by lengthening the cycle of backwashing, can be manufactured in various shapes to facilitate the modification of structure thereof depending on an installation environment, and is compatible with a traditional ballast water processing device.

    본 발명의 선박의 평형수 필터장치에 관한 것으로, 더욱 상세하게는 베이스 플레이트와; 상기 베이스 플레이트의 상면에 장착되는 중공체 형상으로서, 측면에는 내외부로 유체가 유동하는 외부스크린과; 상기 외부스크린에 안치되는 것으로, 외부스크린과 동일형상이되, 외부스크린에 비해 작은 직경으로 형성된 내부스크린과; 상기 외부스크린과 내부스크린 사이의 공간에 적재되는 것으로, 탄성 재질로 형성된 복수의 탄성볼과; 상기 외부스크린과 내부스크린 사이에 안치되는 압축링과; 상기 압축링을 외부스크린과 내부스크린 사이에서 직선왕복 운동하도록 구동시켜 탄성볼을 압축 또는 해제시키는 압축수단;을 포함하여 구성된 것이 특징인 선박의 평형수 필터장치에 관한 것이다. 따라서, 본 발명 선박 평형수 처리용 필터장치는 기존 2차원적인 스크린 형태보다 시간 대비 더 많은 양의 미생물을 처리할 수 있으며, 백와싱(Back washing)주기가 증가되어 운전효율이 증대되며, 다양한 모양으로 제작이 가능하여 설치 환경에 따른 구조 변경이 매우 용이하며, 기존의 평형수 처리장치와의 호환이 가능하다는 등의 현저한 효과가 있다.
