본 고안의 배관을 통하여 유체를 이송시킬때 유체내에 함유되어 있는 철분성분과 각종 이물질들을 제거할 수 있도록 하여 주는 불순물여과장치에 관한 것이다.The present invention relates to an impurity filtration device which removes iron components and various foreign substances contained in a fluid when transferring a fluid through a pipe of the present invention.

이를 좀더 상세히 설명하면 배관을 통하여 이송되어지는 유체에는 철분성분을 포함한 각종 이물질들이 함유되어 있기 때문에 이들을 제거하여 주지 않으면 이들이 배관배부에 적층되어 배관의 기능을 저하시키게 되고 특히 유체가 물인 경우에는 배관을 쉽게 부식시키는 요인이 되는데, 본 고안은 불순물을 여과제거할수 있는 장치를 제공하여 유체속에 함유되어 있는 철분성분을 포함한 이물질을 여과제거함으로서 배관의 기능을 보다 지속적으로 유지시키면서 그 배관의 수명과 보일러계통에 채택할 경우 순환펌프의 수명을 연장시킬수 있도록 하는데 그 목적이 있다.In more detail, since the fluid transported through the pipe contains various foreign substances including iron components, if they are not removed, these fluids are stacked on the pipe and deteriorate the function of the pipe, especially when the fluid is water. Easily corroded, the present invention provides a device that can filter out impurities to filter out foreign substances including iron contained in the fluid to maintain the function of the pipe more continuously while maintaining the life of the pipe and boiler system The purpose is to extend the life of the circulation pump.

종래에도 본 고안의 목적과 유사한 기능을 수행할 수 있는 장치가 제안되어 있는데, 종래의 장치는 국내공개실용신안제91-4564호로서 제4도에 도시된 바와 같은 구조로 되어 있다.Conventionally, an apparatus capable of performing a function similar to the object of the present invention has been proposed. The conventional apparatus has a structure as shown in FIG. 4 as Korean Utility Model No. 91-4564.

본체(30)의 양측에는 유입구(31)와 유출구(32)를 단차를 두어 일체로 형성하고 내부에 망통(39)를 내장시킨 상태에서 분리되는 영구자석(36)이 그 망통(39)의 저부에 연접되어지도록 본체(30)의 저부에 캡(35)을 체결수단에 의해 고정하여서 된 것이다.On both sides of the main body 30, the inlet 31 and the outlet 32 are formed integrally with a step, and the permanent magnet 36 separated in a state in which the mantle 39 is embedded therein is the bottom of the mantle 39. The cap 35 is fixed to the bottom of the main body 30 by the fastening means so as to be connected to the bottom.

특히 망통(39)과 영구자석(36)의 사이에는 고무판(37)을 개입시켜 이물질들이 그 고무판(37)위에 안착하도록 하고 캡(35)을 본체(30)에 채결할때 별도의 오링(38)에 의해 밀폐되게하여 유체가 외부로 누출되지 못하도록 되어 있다.In particular, between the mesh tube 39 and the permanent magnet 36 through the rubber plate 37 to allow foreign matter to be seated on the rubber plate 37 and a separate O-ring 38 when the cap 35 is attached to the main body 30. It is sealed by) to prevent the fluid from leaking to the outside.

이와 같이 된 종래의 여과장치는 유입구(31)와 유출구(32)에 별도의 밸브(34)를 구비하여 배관하도록 되어 있기 때문에 목적외의 부품을 추가로 설치하여 설비비를 상승시키고, 특히 영구자석(36)이 망통(39)과 캡(35)과는 개별적으로 되어 있기 때문에 망통(39)을 통하여 여과되어지는 철분성분을 포함한 각종이물질들이 고무판(37)위에 적층되어지는데, 고무판(37)이 찢겨져 밀폐상태를 유지하여 주지못할 경우에는 각종이물질들이 영구자석(36)에 까지 침투하여 반고체상태로 응고 적층되어지므로 여과장치를 세척정화하기 위하여 캡(35)를 해제시킬때 용이하게 해제시킬수 없다는 것이다.Since the conventional filtration apparatus as described above is provided with pipes having separate valves 34 at the inlet port 31 and the outlet port 32, additional parts other than the purpose are installed to increase the equipment cost, and in particular, the permanent magnet 36 ) Is separate from the net tube 39 and the cap 35, so that various foreign substances including iron components filtered through the net tube 39 are stacked on the rubber plate 37, and the rubber plate 37 is torn and sealed. If it does not maintain the state, various foreign matters penetrate to the permanent magnet 36 and solidified and stacked in a semi-solid state, so that it cannot be easily released when releasing the cap 35 to clean and purify the filtration device.

특히 캡(35)을 해제하여 영구자석(36)을 갖는 고무판(37), 망통(39)을 세정하여야 하는 번거로움이 야기되었다.In particular, the cap 35 has to be released, causing a hassle to clean the rubber plate 37 and the mesh tube 39 having the permanent magnet 36.

또 배관시 여과장치에 별도의 밸브(33)(34)를 채택설치하여 여과장치를 세척장치를 세척정화시 또는 망통(39)을 교체할때 이들밸브(33)(34)를 폐쇄시켜주게 되면 유체가 유출되거나 공기가 유입되는 것을 방지할수 있으나 별도의 밸브(33)(34)를 설치하여야 하므로 배관이 번거로워 배관시간이 오래걸리며 따라서 배관설비비가 상승한다는 폐단이 있다.In addition, when the piping adopts separate valves (33) and (34) installed in the filtration device to close these valves (33) and 34 when cleaning the filtration device when cleaning the cleaning device or when replacing the canister (39) It is possible to prevent the fluid outflow or the inflow of air, but it is necessary to install a separate valve 33, 34 because the pipe is cumbersome piping takes a long time, and thus there is a closed end that the piping equipment costs increase.

반면 밸브(33)를 채택하지 않고 직접 연결할 경우에는 여과장치의 세척정화시 또는 망통(39)을 교체할때 유체가 누출되고 공기가 유입되는 문제점이 있었다.On the other hand, in the case of directly connecting without adopting the valve 33, there is a problem that the fluid is leaked and air is introduced when the cleaning device of the filtration device or when replacing the net tube 39.

따라서 본 고안은 상기 폐단과 문제점을 해소하고자 안출된 것으로서 여과장치내에서 유체의 유출을 용이하게 통제하면서 영구자석도 캡의 저부내면에 매설하여서된 것이다.Therefore, the present invention is intended to solve the above-mentioned end and the problem is to embed the permanent magnet in the bottom inner surface of the cap while easily controlling the outflow of the fluid in the filtration device.

이하 본 고안을 첨부 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

유입관 과유출관이 형성된 본체의 저부에 캡을 결합시키고 그내부에 망토와 영구자석을 내장하여서된 것에 있어서, 본체(2)의 저부에 밀폐란(13)을 개입시켜 내하방에 영구자석(12)이 매설된 캡(10)을 체결하되 그 본체(2)의 내부에는 유입통(21)에 개방부(25)와 여과망(26)이 대응되게 형성된 여과틀(20)을 내장하여서된 것이다.The cap is coupled to the bottom of the main body in which the inflow pipe and the outflow pipe are formed, and the cape and the permanent magnet are embedded therein, and the permanent magnet 12 is disposed downward and downward through the closed column 13 at the bottom of the main body 2. ) Is embedded in the cap 10 is buried in the interior of the main body (2) is built in the filter frame 20 formed to correspond to the opening portion 25 and the filter net 26 in the inlet 21.

특히 본체(2)의 상면에는 통공부(4)와 삽탈홈(5)을 일체로 통공하여 외주연에 플랜지(3)를 형성하고 유입통(21)의 상면에는 돌출면(24)과 고정편(23)을 형성하여 고정편(23)을 삽탈홈(5)의 상부로 노출시켜 플랜지(3)위에서 회전시킴에 따라 유입통(21)의 개방부(25)와 여과망(20)이 유입관(6) 유출관(7)과 동일선상 또는 교차선상에 위치하도록 하며, 유입통(21)이 내상측에는 여과망(26)과 나란히하는 차폐판(27)을 하향연설하고 외측면에는 밀폐면(2)을 대응하되 형성하여서된 것이다.In particular, the upper surface of the main body 2 through the through-hole 4 and the insertion groove 5 integrally formed to form a flange (3) on the outer periphery, the upper surface of the inflow tube 21, the protruding surface 24 and the fixing piece (23) is formed to expose the fixing piece (23) to the upper portion of the insertion groove (5) to rotate on the flange (3) as the opening 25 of the inlet tube 21 and the filter net 20 is the inlet pipe (6) It is located on the same line or cross line with the outlet pipe (7), the inlet tube 21 is in the upper inner side down the shield plate 27 parallel to the filter net 26 and the outer surface is sealed surface (2 ) To correspond but form.

이와 같이 구성된 본 고안의 여과장치(1)는 통상의 방법과 동일하게 유체이송관의 중간에 설치되며, 유입관(6)의 나사부(6-1)와 유출관(7)의 나사부(7-1)에 이송관(도시하지 아니함)을 직접나사결합한다.The filtration device 1 of the present invention configured as described above is installed in the middle of the fluid transfer pipe in the same manner as the conventional method, and the threaded portion 6-1 of the inlet pipe 6 and the screwed portion 7-1 of the outlet pipe 7 are provided. Screw a transfer pipe (not shown) directly into

제2도에 도시된 바와 같이 여과틀(20)을 본체(2)에 내장시킨 상태에서 밀폐판(13)을 재치시켜 캡(10)을 상호간의 나사부(2-1)(11)와 같은 체결수단에 의해 고정시켜 준다.As shown in FIG. 2, the cap 10 is fastened to the same screw portions 2-1 and 11 by placing the sealing plate 13 in a state in which the filter frame 20 is embedded in the main body 2. It is fixed by means.

삽탈홈(5)에 고정편(23)을 삽입하여 외부로 노출시키면 유입통(21)의 밀폐돌설면(22)이 유입관(6)과 유출관(7)의 내부 선단을 폐쇄시키게 되며, 고정편(23)을 파지하여 회전시키면 제3도에 도시된 바와 같이 개방부(25)가 선행부에 위치하고 여과망(26)이 후행부에 위치하게 된다.When the fixing piece 23 is inserted into the inserting groove 5 and exposed to the outside, the sealing projection surface 22 of the inflow tube 21 closes the inner ends of the inflow pipe 6 and the outflow pipe 7, Gripping and rotating the fixing piece 23 causes the opening 25 to be positioned at the front and the filtering net 26 at the rear, as shown in FIG.

본 고안의 여과장치(1)는 제3도에 도시된 바와 같이하여 사용되어 진다. 유입관(6)을 통하여 유입된 유체는 개방부(25)를 통하여 유입통(21)의 내부에 인입되는데 인입된 유체는 차폐판(27)에 의하여 하향유도된후 다시 상승하여 각종 이물질들이 여과망(26)에 여과되어 정화된 유체만이 유출관(7)을 통하여 유출되어 진다.The filtration device 1 of the present invention is used as shown in FIG. The fluid introduced through the inlet pipe (6) is introduced into the inside of the inlet tube (21) through the opening 25, the introduced fluid is guided down by the shielding plate 27 and then rises again and various foreign matters are filtered out. Only the fluid filtered and purified by 26 flows out through the outflow pipe 7.

특히 유체가 유입통(21)의 내부에 인입되어 유출될때 금속성물질은 영구자석(12)의 자력에 이끌리어 각종 이물질과 함께 밀폐판(13)위에 적층되는데 돌설봉(14)에 의해 밀폐판(13)위에 고르게 분산되어 적층되어 진다.In particular, when the fluid enters and exits the inlet 21, the metallic material is attracted to the magnetic force of the permanent magnet 12 and is laminated on the sealing plate 13 together with various foreign matters. ) Evenly distributed on the stack.

본 고안에서는 영구자석(12)을 캡(10)의 내부에 노출되지 않도록 매설하였기 때문에 분해조립시 영구자석(12)만을 특별히 관리할 필요가 없게 된다.In the present invention, since the permanent magnet 12 is embedded so as not to be exposed to the inside of the cap 10, it is not necessary to specifically manage only the permanent magnet 12 during disassembly and assembly.

또한 밀폐판(13)은 본체(2)와 캡(10)을 나사결합할때 상호 밀폐상태를 유지할 수 있도록 나사부(11)의 내주연과 일치하도록 충분한 크기로 하여 주는 것이 바람직하다.In addition, the sealing plate 13 is preferably sized to be sufficient to match the inner circumference of the screw portion 11 to maintain the mutual sealing state when screwing the main body 2 and the cap 10.

이와 같이 하여 본 고안의 여과장치(1)를 일정기간사용한 다음 내부를 청소하고자 할때에는 여과틀(20)의 고정편(23) 회전시켜 제2도에 도시된 바와 같이 밀폐돌설면(22)에 의해 유입관(6)과 유출관(7)을 폐쇄시켜주면 유입관(6)으로 부터는 유체의 유출이 방지되고, 유출관(7)으로는 공기가 유입되는 것이 차단된다.In this manner, when the filtration device 1 of the present invention is used for a certain period of time, and then the inside of the filtration device is to be cleaned, the fixing piece 23 of the filtration frame 20 is rotated to seal the sealing surface 22 as shown in FIG. When the inlet pipe 6 and the outlet pipe 7 are closed by this, the outflow of the fluid from the inlet pipe 6 is prevented, and the inflow of the air to the outlet pipe 7 is blocked.

이와 같이 한후 캡(10)을 역회전시켜 밀폐판(13) 여과틀(20)을 분리한 후 별도의 세척수단에 의해 깨끗하게 세정시킨 다음 상기의 역순의 방법에 의해 재결합시키면 간단하게 본 고안의 여과장치(10)를 세정시킬수 있다.After this, the cap 10 is rotated in reverse to separate the filter plate 20 of the sealing plate 13, and then washed clean by a separate washing means, and then recombined by the reverse method described above. The device 10 can be cleaned.

따라서 본 고안에 따르면 유체내의 함유되어 있는 각종 이물질들을 여과장치(10)에 의해 정화시켜줌으로서 순환펌프의 내부에 이물질이 적층되는것등을 예방할수 있어 기능을 항상 동일하게 유지시켜줄수 있고, 또 여과장치(1)도 간단한 조작에 의해 유체의 흐름을 자체차단한 상태에서 내부정화 및 교체를 용이하게 하여줌은 물론 각부품 즉 여과를, 캡 및 밀폐란을 용이하게 세정할수 있도록 된 것이며, 특히 영구자석(12)을 캡(10)에 내부에 내장하여 줌으로서 여과장치의 전장의 길이를 크게 줄일수 있도록 된 유용한 것이다.Therefore, according to the present invention, by purifying various foreign substances contained in the fluid by the filtering device 10, it is possible to prevent the accumulation of foreign substances in the circulation pump, etc., thereby maintaining the same function at all times, and the filtering device. (1) also facilitates internal cleaning and replacement in the state of blocking the flow of fluid by simple operation, and also makes it easy to clean each part, that is, the filtration, the cap and the closed column, especially the permanent magnet. It is useful that the length of the length of the filtration device can be greatly reduced by enclosing (12) inside the cap 10.
