둥글게 감긴 타공판(110)의 겹쳐지는 양 쪽 가장자리에서 한쪽의 핀(130)을 반대쪽의 필터링구멍에 삽입시켜 결합하는 단계; 를 포함하는 것을 특징으로 하는 해수용 판형열교환기의 인라인 필터 제조방법에 관한 것이며, 상기 핀 조립형 필터 제조방법에 의해 제조된 해수용 판형열교환기의 인라인 필터에 관한 것이다.Inserting one of the fins (130) at opposite edges of the rounded perforated plate (110) in the opposite filtering hole; The present invention relates to a method of manufacturing an in-line filter of a plate-type heat exchanger for seawater, and to an in-line filter of a plate-type heat exchanger manufactured by the method of manufacturing a pin-assembly type filter.

종래 해수용 판형열교환기의 인라인 필터는 타공판을 둥글게 감은 다음 맞닿는 부분을 용접에 의해 접합하거나 리벳을 박아서 접합하는 것이었으며, 접합부분이 해수에 의해 부식되는 문제점이 있었으며, 또한 필터 외부에 위치하는 인라인 전열판과 간격이 벌어져 필터에 걸리는 고압 해수에 의해 필터가 파손되는 문제점이 있었다.Conventionally, an inline filter of a plate type heat exchanger for seawater has a problem that a seam portion is corroded by seawater, and an inline There is a problem that the filter is broken by the high-pressure seawater which is caught by the filter due to a gap between the heat transfer plate and the heat transfer plate.

본 발명은 상술한 종래기술들의 문제점을 해소한 새로운 구조의 조립식 해수용 판형열교환기의 인라인 필터에 관한 것으로, 소정두께의 티타늄판에 직경 0.5-2mm의 필터링구멍을 형성한 타공판을 제조하고, 타공판의 한 쪽 가장자리에 필터링구멍에 삽입되는 핀을 1-3개 라인으로 형성하며, 필터링구멍과 핀이 형성된 타공판을 둥글게 감아서 핀 라인이 있는 가장자리가 그 반대쪽 가장자리와 겹쳐지게 한 다음, 핀이 필터링구멍에 삽입되어 고정되도록 함으로써 필터 직경을 그 외부에 위치하는 인라인 전열판에 밀착되도록 조절할 수 있도록 형성된 것이다.The present invention relates to an inline filter for a prefabricated plate-type heat exchanger for a prefabricated seawater having a new structure that overcomes the above-described problems of the prior art, and has a structure in which a perforated plate having a filtering hole having a diameter of 0.5-2 mm is formed on a titanium plate having a predetermined thickness, Forming a 1-3-line pin to be inserted into the filtering hole on one side of the filtering hole and rounding the perforated plate with the finishing hole so that the edge with the pin line overlaps the opposite edge, So that the diameter of the filter can be adjusted so as to be in close contact with the inline heat transfer plate located outside the filter.

본 발명은 소정두께의 티타늄판에 직경 0.5-2mm의 필터링구멍을 형성한 타공판을 제조하고, 타공판의 한 쪽 가장자리에 필터링구멍에 삽입되는 핀을 2,3개 라인으로 형성하며, 필터링구멍과 핀이 형성된 타공판을 둥글게 감아서 핀 라인이 있는 가장자리가 그 반대쪽 가장자리와 겹쳐지게 한 다음, 핀이 필터링구멍에 삽입되어 고정되도록 형성함으로써 핀을 필터링구멍을 옮겨 조립하여 필터 직경을 전열판에 밀착되는 직경으로 가변할 수 있도록 형성된 해수용 판형 열교환기의 인라인 필터를 제공하는 것을 목적으로 한다.According to the present invention, a perforated plate having a filtering hole having a diameter of 0.5-2 mm is formed on a titanium plate having a predetermined thickness, a fin inserted into one of the filtering holes at one edge of the perforated plate is formed into two or three lines, And then the pin is inserted and fixed in the filtering hole, so that the pin is moved by assembling the filtering hole and assembled to the filter so that the diameter of the filter becomes close to the diameter of the heat transfer plate And an object of the present invention is to provide an inline filter of a plate heat exchanger for seawater which can be varied.

이러한 목적을 달성하기 위하여, 본 발명은 소정두께의 티타늄판에 직경 0.5-2mm의 필터링구멍(115)을 소정 간격으로 형성한 타공판(110)을 제조하는 단계;In order to achieve the above object, the present invention provides a method of manufacturing a perforated plate, comprising the steps of: preparing a perforated plate 110 having a predetermined thickness of titanium plates and having filtering holes 115 having a diameter of 0.5-2 mm at predetermined intervals;

타공판(110)의 한 쪽 가장자리에 필터링구멍(115)에 맞게 삽입되는 직경을 하고 필터링구멍(115)에 맞게 삽입되도록 간격과 위치가 형성된 소정 높이의 핀(130)을 1-3개 라인으로 형성하는 단계; A fin 130 having a predetermined diameter and a predetermined height formed at one side of the perforated plate 110 so as to fit into the filtering hole 115 and inserted into the filtering hole 115 is formed into one to three lines ;

필터링구멍과 핀이 형성된 타공판(110)을 둥글게 감는 단계; Winding a perforated plate (110) having a filtering hole and a pin rounded;

둥글게 감긴 타공판(110)의 겹쳐지는 양 쪽 가장자리에서 한쪽의 핀(130)을 반대쪽의 필터링구멍에 삽입시켜 결합하는 단계; 를 포함하는 것을 특징으로 하는 해수용 판형열교환기의 인라인 필터 제조방법에 관한 것이며, 상기 핀 조립형 필터 제조방법에 의해 제조된 해수용 판형열교환기의 인라인 필터에 관한 것이다.Inserting one of the fins (130) at opposite edges of the rounded perforated plate (110) in the opposite filtering hole; The present invention relates to a method of manufacturing an in-line filter of a plate-type heat exchanger for seawater, and to an in-line filter of a plate-type heat exchanger manufactured by the method of manufacturing a pin-assembly type filter.

본 발명은 해수용 판형열교환기의 인라인 필터에 관한 것으로, 해수에는 소금기와 각종 이물질이 많이 포함되어 있기 때문에 해수 부식에 약한 용접, 리벳 등의 사용을 없앰으로써 부식을 방지한 것이며, 또한 본 발명은 핀을 필터링구멍에 삽입하여 고정하도록 형성함으로써 전열판에 밀착되도록 필터의 직경을 편리하게 조절할 수 있도록 형성한 것이다.The present invention relates to an inline filter of a plate-type heat exchanger for seawater. Since seawater contains a large amount of salt and various foreign substances, it prevents corrosion by eliminating the use of weak welding, rivets, etc., The diameter of the filter can be easily adjusted so as to be closely attached to the heat transfer plate by inserting and fixing the fin in the filtering hole.

먼저, 필터의 사이즈를 고려하여 소정 크기로 소정두께의 티타늄 판재를 사각형으로 절단한 다음, 필터링구멍(115)을 소정 간격으로 형성한 타공판을 만든다. First, a titanium plate having a predetermined thickness is cut into a square shape in consideration of the size of the filter, and then a perforated plate having filtering holes 115 formed at predetermined intervals is formed.

필터링 구멍은 0.5-2mm의 범주에서 선택된 하나의 크기로 타공한다.The filtering holes are perforated to a size selected from 0.5-2 mm.

타공판의 한쪽 가장자리를 따라 핀을 웰딩에 의해 융착하여 핀라인을 형성하며, 핀라인은 1-3개가 바람직하며 너무 많아도 조립 시 핀을 구멍에 맞추어 넣을 때 어려움이 있다.Fins are welded along one edge of the perforated plate by welding to form pin lines. The number of pin lines is preferably 1-3, and it is difficult to fit the pins into the holes when assembling.

핀은 타공판에 수직으로 형성되며 전기 아크에 의해 직접 녹여 붙이는 것으로 타공판과 일체로 견고하게 형성되며 핀 라인은 타공판을 말았을 때 필터의 길이방향으로 형성되게 된다.The fin is formed perpendicularly to the perforated plate and directly melted and attached by an electric arc. The pin is integrally formed with the perforated plate, and the pin line is formed in the longitudinal direction of the filter when the perforated plate is rolled.

핀 라인이 필터의 길이방향이 되도록 하여 타공판을 둥글게 말게 되며, 핀 라인은 반대쪽 가장자리에 포개지며, 반대쪽 가장자리에 형성된 필터링구멍에 맞게 삽입되도록 형성된다.The perforated plate is rounded so that the pin line is in the longitudinal direction of the filter, and the pin line is formed to be superimposed on the opposite edge and fit into the filtering hole formed on the opposite edge.

필터링구멍은 핀 라인의 핀과 맞게 위치와 간격으로 형성되고, 이들 라인 사이에 형성되는 빈 공간마다 사이구멍을 형성하여 필터링구멍이 이루어진다.The filtering holes are formed at positions and intervals so as to be aligned with the pins of the pin line, and a filtering hole is formed by forming a through hole for each empty space formed between these lines.

핀 라인의 핀은 사이구멍에는 삽입되지 않으며, 핀 라인 핀과 동일한 위치및 간격으로 형성된 필터링구멍에 삽입된다.The pins of the pin line are not inserted into the through holes, but are inserted into the filtering holes formed at the same positions and intervals as the pin line pins.

핀 라인의 핀 수와 필터링구멍 라인의 구멍 수가 같은 수로 형성할 수 있지만 반드시 그럴 필요는 없으며 필터링구멍보다 핀의 수를 적게 형성할 수 있다.Although the number of pins of the pin line and the number of holes of the filtering hole line can be the same, it is not necessarily required, and the number of the pins can be made smaller than the filtering hole.

이와 같이 본 발명의 필터는 핀을 이동하여 다른 필터링구멍에 삽입 고정할 수 있기 때문에 직경을 전열판의 직경에 맞추어 밀착되게 조절 형성할 수 있는 이점이 있으며, 고압의 해수 필터링 과정에서 필터 파손 등의 문제점을 방지하는 것이다.Since the filter of the present invention can be inserted and fixed in the other filtering holes, the filter of the present invention has an advantage that it can be adjusted to be in close contact with the diameter of the heat transfer plate, and problems such as filter breakage .

본 발명은 핀을 필터링구멍에 삽입하여 조립하도록 형성하는 것으로 필터 외부에 위치하는 인라인 전열판에 밀착되도록 필터 직경을 조절할 수 있으며, 이에 의해 고압의 해수로 인한 필터 파손 등을 방지하는 효과가 있다.In the present invention, the fin is formed by inserting into the filtering hole, and the filter diameter can be adjusted so as to be in close contact with the inline heat transfer plate located outside the filter, thereby preventing the filter from being damaged due to high pressure seawater.

또한 본 발명은 해수 필터과정에서 발생하는 이물질을 세정하기 위하여 필터를 분리시켜 편 다음 쉽고 효과적으로 세정작업을 할 수 있는 효과가 있다.In addition, the present invention has an effect that a filter can be separated in order to clean a foreign object generated in a seawater filter process, and then the cleaning operation can be performed easily and effectively.

또한 본 발명은 필터 및 핀의 재질을 티타늄 재질로 형성함으로써 파손과 변형하지 않도록 하면서 해수로부터 부식을 방지하는 효과가 있다.In addition, the present invention has the effect of preventing corrosion from seawater while preventing the filter and the pin from being damaged or deformed by forming the material of the filter and the pin from a titanium material.

또한 본 발명은 구조가 간단하고 제조 및 조립이 단축되어 생산성 향상과 원가절감에 기여하는 효과가 있다.Further, the present invention has the effect of contributing to productivity improvement and cost reduction by simplifying the structure and shortening manufacturing and assembling.

도 2는 본 발명의 타공판 일 실시예를 도시한 것으로, 타공판(110) 한 쪽 가장자리에는 핀(130)이 소정간격으로 형성되어 라인을 형성하고, 핀 라인 우측에는 핀과 같은 위치 및 간격의 필터링구멍(115) 라인이 핀 라인과 같은 간격으로 다수 개 형성된 것이다.FIG. 2 illustrates one embodiment of a perforated plate according to the present invention. A pin 130 is formed at one edge of a perforated plate 110 to form a line, and on the right side of the pin line, A plurality of holes 115 are formed at the same intervals as the pin lines.

핀 라인과 동일한 간격으로 형성된 필터링구멍(115) 라인 사이 빈 공간에는 사이구멍(116) 라인이 형성되어 있다. 이들 사이구멍(116)에는 핀이 삽입되지 않는다.In the empty space between the lines of the filtering holes 115 formed at the same intervals as the pin lines, lines 116 are formed. No pin is inserted into the hole 116 between them.

핀은 웰딩(welding)에 의해 타공판에 직각으로 아크 융착되며, 핀 라인은 1-3줄이 바람직하다.The fins are arc fused at right angles to the perforated plate by welding, and the fin lines are preferably 1-3 lines.

티타늄 재질의 타공판과 핀은 강도가 높고 변형과 부식을 방지할 뿐 아니라 세정 시 유연한 성질에 의해 잘 펴진 상태에서 편리하고 효과적으로 세정할 수 있도록 하는 것이다.Titanium perforated plates and fins are high in strength and prevent deformation and corrosion, as well as being flexible and easy to clean in a well-extended condition due to their flexibility in cleaning.

필터링구멍과 핀이 형성된 타공판을 기계적으로 둥글게 말게 되며, 둥글게 말린 핀 라인은 그 반대쪽 가장자리가 겹쳐지게 되며, 핀(130)은 겹치지는 위치의 필터링구멍(115) 라인의 필터링구멍에 삽입 조립된다.The perforated plate with the filtering hole and the pin is mechanically rounded, the rounded pin line overlaps the opposite edge, and the pin 130 is inserted and assembled into the filtering hole of the filtering hole 115 line at the overlapping position.

본 실시예서는 핀과 필터링구멍이 줄에 형성된 수가 같게 형성되어 있으나 핀의 수를 필터링구멍보다 적게 형성할 수 있다. In this embodiment, the number of the pins and the number of the filtering holes are the same, but the number of the pins is less than the number of the filtering holes.

만약 필터링직경을 작게 형성하고자 한다면 핀을 더 안쪽의 필터링구멍에 삽입 결합하면 된다.If you want to make the filtering diameter smaller, you can insert the pin into the inside filtering hole.
