나선형 지지구가 구비된 여과장치{FILTER FOR WATER}Filtration device with spiral support {FILTER FOR WATER}

본 발명은 나선형 지지구가 구비된 여과장치에 관한 것으로, 더욱 상세하게는 밸러스트 탱크의 물에 혼입된 오염입자를 여과에 의해 제거하고, 역세척이 용이하도록 한 나선형 지지구가 구비된 여과장치에 관한 것이다.The present invention relates to a filtration device provided with a spiral support, and more particularly, to a filtration device provided with a spiral support for removing contaminants mixed in water in a ballast tank by filtration and for easy backwashing. It is about.

일반적으로 밸러스트 탱크는 선박의 화물의 균형을 맞추기 위해 설치된 것으로, 밸러스트 탱크 내에 바닷물을 저수시키거나 배출시킴으로써 균형을 유지하게 된다.In general, ballast tanks are installed to balance a ship's cargo, and the ballast tank is balanced by storing or draining seawater in the ballast tank.

그런데, 바닷물을 저수시키는 과정에서 해조류 및 해양생물이 동반 유입되며, 바닷물을 배출시킬 때 해조류 및 해양생물이 배출됨으로써 외래종의 유입과 오염물질의 유입 등 해양 생태계를 혼란시키며 오염시키는 원인이 된다. However, algae and marine life are introduced in the process of storing the sea water, and when the seawater is discharged, algae and marine life are discharged, which causes disruption and pollution of the marine ecosystem such as inflow of alien species and inflow of pollutants.

따라서, 밸러스트 탱크 내에 바닷물을 저수시키거나 배출시킬 때 필터링작업에 의해 오염물질을 제거해줄 필요가 있는데, 일반적인 종래 필터는 오염물질을 제거할때 물의 흐름이 현저히 느려지게 되므로 대량의 바닷물을 필터링하기가 어려운 문 제점이 있었다.Therefore, it is necessary to remove contaminants by filtering when storing or discharging seawater in the ballast tank. In general, a conventional filter is required to filter a large amount of seawater since the flow of water is significantly slowed down when removing contaminants. There was a difficult problem.

본 발명은 상기한 종래 기술의 문제점을 해소하기 위해 안출된 것으로, 양측이 개구된 파이프형태로 필터를 형성하고, 강성을 강화하기 위해 필터의 내부에 나선형태의 지지수단을 부가함으로써 충격변형을 방지하고, 여과되는 물이 와류를 형성함으로써 이물질의 고착률을 저하시킴으로써 필터 성능을 최적화할 수 있으며, 대량의 물을 속도저하없이 여과시킬 수 있도록 한 나선형 지지구가 구비된 여과장치를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems of the prior art, forming a filter in the form of a pipe on both sides, and to prevent the impact deformation by adding a helical support means inside the filter to enhance rigidity In addition, it is possible to optimize the filter performance by lowering the rate of fixation of foreign substances by forming a vortex of the filtered water, and to provide a filtration device equipped with a spiral support for filtering large quantities of water without slowing down. There is this.

상기한 본 발명의 목적은, 외부의 여과재와, 상기 여과재의 내부에 삽입되는 지지수단으로 구성된 것이며, 상기 지지수단은 나선형태로 형성된 것으로, 유입된 후 여과재를 통과하여 여과되는 물이 상기 지지수단에 의해 와류를 형성하면서 통과되도록 한 것을 특징으로 하는 나선형 지지구가 구비된 여과장치에 의해 달성될 수 있다.An object of the present invention described above is composed of an external filter medium and a support means inserted into the filter medium, wherein the support means is formed in a spiral shape, and water flowing through the filter medium after being introduced is filtered through the support means. It can be achieved by a filtration device provided with a spiral support characterized in that it is passed while forming a vortex by.

상기 지지수단은 평철을 나선형으로 형성시킨 것을 특징으로 한다.The support means is characterized in that the flat iron spirally formed.

상기 여과재는 중공사막필터인 것을 특징으로 한다.The filter medium is characterized in that the hollow fiber membrane filter.

본 발명에 따르면, 혼탁한 유입수를 여과시켜 정제된 물을 얻을 수 있고, 와류 형성에 의해 필터 및 지지수단에 오염물질의 누적을 최소화할 수 있어, 수명이 연장될 수 있고, 역세척 주기를 길어지게 할 수 있으며, 필터 성능을 최적화할 수 있는 효과가 있다.According to the present invention, it is possible to obtain purified water by filtering the turbid influent, and to minimize the accumulation of contaminants in the filter and the support means by the vortex formation, the life can be extended, and the backwash cycle is lengthened And the effect of optimizing the filter performance.

이하 본 발명의 바람직한 실시예를 첨부된 도면을 토대로 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

첨부된 도 1은 본 발명에 따른 나선형 지지구가 구비된 여과장치에 대한 분해 사시도이고, 도 2는 본 발명에 따른 나선형 지지구가 구비된 여과장치에 대한 종단면도이다. Attached Figure 1 is an exploded perspective view of a filtration device with a spiral support according to the present invention, Figure 2 is a longitudinal sectional view of the filtration device with a spiral support according to the present invention.

도 1 및 도 2에 나타낸 바와 같이, 본 발명에 따른 나선형 지지구가 구비된 여과장치(A)는, 양단이 개구되고 내부에 통로가 형성된 여과재(2)와, 상기 여과재(2)의 내부에 삽입되는 지지수단(4)으로 구성된 것이며, 상기 지지수단(4)은 나선형태로 형성된 것으로, 유입된 후 여과재(2)를 통과하여 여과되는 물이 상기 지지수단(4)에 의해 와류를 형성하면서 통과되도록 한다.As shown in Fig. 1 and Fig. 2, the filtration device A with a spiral support according to the present invention includes a filter medium 2 having both ends open and a passage formed therein, and inside the filter medium 2; It is composed of a support means 4 to be inserted, the support means 4 is formed in a spiral shape, while the water is introduced and filtered through the filter medium (2) forms a vortex by the support means (4) Allow it to pass.

상기 지지수단(4)은 소정의 두께를 갖는 평철을 나선형으로 형성시킨다. 특히, 도 1 및 도 2의 확대도면에 나타낸 바와 같이, 상기 평철의 상면을 내측으로 오목하게 요입시켜 상면 안쪽에 가이드턱(42)이 형성된다.The support means 4 spirally forms flat iron having a predetermined thickness. In particular, as shown in the enlarged view of FIGS. 1 and 2, the guide jaw 42 is formed inside the upper surface by recessing the upper surface of the flat iron inwardly.

따라서, 물이 지지수단(4)의 형상을 따라 와류로 흐르면서 상기 가이드턱(42)에 부딪쳐 외측으로 분출됨으로써 여과재(2)로 분사되듯이 뿌려지게 된다.Therefore, water is sprinkled as it is sprayed to the filter medium 2 by flowing into the vortex along the shape of the support means 4 and hitting the guide jaw 42 to be ejected outward.

상기 여과재(2)는 양단이 개구되고 내부에 통로가 형성되어 파이프형태로 형성된 것이며, 여러가지 형태의 필터류가 사용될 수 있으며, 본 실시예에서는 중공사막필터가 사용되었다. The filter material 2 is open at both ends and has a passage formed therein, which is formed in a pipe shape, and various types of filters can be used. In this embodiment, a hollow fiber membrane filter is used.

상기 여과재(2)의 내부에 지지수단(4)을 삽입하여 지지되도록 한다.The support means 4 is inserted into the filter medium 2 so as to be supported.

또한, 여과재(2)의 상부 개구부에 원수유입구(50)를 갖는 캡(5)이 결합될 수도 있다. In addition, a cap 5 having a raw water inlet 50 may be coupled to the upper opening of the filter medium 2.

상기 여과재(2)의 하부 개구부는 개구된 상태로 둔다.The lower opening of the filter medium 2 is left open.

따라서, 상부에 형성된 원수유입구(50)를 통해 원수(바닷물)가 유입되면, 여과재(2)의 내측 통로를 타고 흐르되, 스프링 형상으로 된 지지수단(4)을 타고 흐르면서 와류가 형성되고, 아울러 여과재(2)를 통과하면서 원수에 혼입된 탁도물질 및 오염물질은 제거되고, 정수처리된다. Therefore, when the raw water (sea water) is introduced through the raw water inlet 50 formed in the upper portion, while flowing through the inner passage of the filter medium 2, the vortex is formed while flowing through the support means 4 made of a spring, The turbidity and contaminants mixed in the raw water while passing through the filter medium 2 are removed and purified.

그러므로, 와류형성에 의해 내부의 지지수단(4) 및 여과재(2)에 오염물질이 누적되는 비율이 아주 낮아지게 되므로 좀더 오래 사용할 수 있고, 그만큼 역세척 주기도 길어지게 된다.Therefore, the rate of accumulation of contaminants in the support means 4 and the filter medium 2 by the vortex formation becomes very low, so that it can be used longer, and the backwashing cycle is also longer.

비록 본 발명이 상기 언급된 바람직한 실시예와 관련하여 설명되어졌지만, 발명의 요지와 범위로부터 벗어남이 없이 다양한 수정 및 변형이 가능한 것은 당업자라면 용이하게 인식할 수 있을 것이며, 이러한 변경 및 수정은 모두 첨부된 청구의 범위에 속함은 자명하다.Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, all such modifications and modifications being attached It is obvious that the claims belong to the claims.
