본 고안은 마이크로 필터(micro filter)에 관한 것으로, 더 상세히는 필터의 고정구조를 개선한 마이크로 필터에 관한 것이다.The present invention relates to a micro filter, and more particularly to a micro filter having an improved fixing structure of the filter.
마이크로 필터는 다공성(多孔性) 세라믹(ceramic) 소결체(燒結體) 등으로 형성된 필터체를 구비하여 수 내지 수십 미크론(㎛) 크기의 미세한 여과를 행하는 것으로, 예를 들어 브라운관에 사용되는 블랙매트릭스용 흑연도료의 여과등에 사용되는 것이다. 이와 같은 마이크로 필터의 한 구성예를 제 1 도에 보인 바, 이는 하우징(1)의 상하에 돌출형성된 림(3a,3b)으로 필터체(2)를 접촉지지시켜 축 방향 유동을 방지하고, 하우징(1)의 중심에 고정된 중심축(4)과 필터체(2)이 내경부(2a) 사이에 스프링(5)을 설치함으로써 필터체(2)의 원주방향 유동을 방지하도록 된 구성이었다.(미설명 부호는 후술하는 본고안의 설명참조)The micro filter comprises a filter body formed of a porous ceramic sintered body or the like, and performs fine filtration of several to several tens of microns (µm), for example, for a black matrix used in a CRT. It is used for filtration of graphite paint. One configuration example of such a micro filter is shown in FIG. 1, which is in contact with the filter body 2 by rims 3a and 3b protruding above and below the housing 1 to prevent axial flow, and The center shaft 4 fixed to the center of (1) and the filter body 2 were comprised so that the circumferential flow of the filter body 2 may be prevented by providing the spring 5 between the inner diameter part 2a. (Refer to the explanation of this draft which will be described later for unexplained symbols)
그런데 종래의 마이크로 필터는 스프링(5)이 필터체(2)를 완전히 고정시키는 것이 아니라 탄성적으로 지지하는 것이므로 필터체(2)를 하우징(1)내에 고정시킬때 탄성적으로 변형하여 필터체(2)를 정확히 중심을 맞춰 위치시키지 못하게 되고, 이에 따라 필터체(2)와 하우징(1)사이에 틈새가 발생하여 이 틈새로 여과될 유체가 통과함으로써 수 내지 수십 ㎛단위의 미세 여과가 전혀 이뤄지지 않게 되는 문제가 발생되었다. 이와 같은 문제는 필터체(2)가 정위치 하였는지 확인할 방법이 없으므로 마이크로 필터의 제작에 있어서는 매우 심각한 문제였던 것이다.However, in the conventional micro filter, the spring 5 does not completely fix the filter body 2 but elastically supports it, so that the filter body 2 is elastically deformed when the filter body 2 is fixed in the housing 1. 2) cannot be precisely centered, and as a result, a gap is generated between the filter body 2 and the housing 1, so that the fluid to be filtered through the gap passes through the microfiltration of several to several tens of micrometers. There was a problem that would not. This problem was a very serious problem in the manufacture of the micro filter because there is no way to check whether the filter body 2 is in place.
본 고안은 이와같은 종래의 문제점을 해결하고자 안출된 것으로, 필터체를 정위치시켜 조립불량을 방지할수 있는 마이크로 필터를 제공하는 것을 그 목적으로 한다.The present invention has been made to solve such a conventional problem, an object of the present invention is to provide a micro filter that can prevent the assembly failure by positioning the filter body.
이와 같은 목적을 달성하기 위한 본 고안 마이크로 필터는 하우징의 내부에 중공 원통형의 필터체를 고정지지하여 도입 포오트로 유입된 유동체를 미세여과한 뒤 도출 포오트로 배출시키는 마이크로 필터에 있어서, 상기 하우징의 상하로 연장되어 고정되는 중심축의 외주에 각각 복수의 연통구멍에 형성된 적어도 2개이상의 지지플랜지를 고정 설치하여 상기 필터체의 내경부를 접촉지지하도록 구성된 것을 특징으로 한다.The present invention to achieve the object of the micro-filter is a micro-filter for holding a hollow cylindrical filter body inside the housing fixed to the micro-filtration of the fluid introduced into the introduction port and discharged to the discharge port, the housing It characterized in that it is configured to contact and support the inner diameter portion of the filter body by fixing at least two or more support flanges formed in the plurality of communication holes on the outer periphery of the central axis that is fixed to extend up and down.
이하에 첨부된 도면을 참조로 하여 본 고안의 한 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제 2 도에 보인 본 고안 마이크로 필터는 원통형의 하우징(housing; 1)의 상,하에 각각 림(rim; 3a,3b)이 형성되어 다공성 세라믹 소결체 등으로 형성된 중공 원통형의 필터체(2)를 축방향으로 지지하고 있으며, 하우징(1)과 필터체(2)의 외주 사이의 공간으로는 도입 포오트(inlet port; 6)가, 필터체(2)의 내경부(2a)측의 공간으로는 도출 포오트(outlet port; 7)가 각각 연통된다.The micro-filter of the present invention shown in FIG. 2 has a rim (3a, 3b) formed at the top and bottom of the cylindrical housing (1), respectively, to form a hollow cylindrical filter body (2) formed of a porous ceramic sintered body or the like. Direction, the inlet port 6 is a space between the housing 1 and the outer periphery of the filter body 2 as a space on the inner diameter portion 2a side of the filter body 2. Derivative port 7 is communicated with each other.
하우징(1)의 중심에는 중심축(4)이 연장되어 고정 설치되며 이 중심축(4)에는 복수의 연통구멍(8a)이 형성된 적어도 둘이상의 지지 플랜지(8)가 고정 설치되어 필터체(2)의 내경부(2a)와 접촉 지지하고 있다.The central shaft 4 extends and is fixedly installed at the center of the housing 1, and at least two or more support flanges 8 having a plurality of communication holes 8a are fixedly installed at the central shaft 4 so as to filter the filter body 2. Contact with and support the inner diameter part 2a of ().
여기서 연통구멍(8a)은 여과되는 유동체의 상하방향 유동을 가능하게 하도록 형성된 것이며, 지지 플랜지(8)와 필터체(2)의 내경부(2a)간의 허용공차는 필터체(2)와 림(3a,3b)간에 틈새가 발생하지 않을 정도이면 충분하다.Here, the communication hole 8a is formed to enable the up-down flow of the fluid to be filtered, and the tolerance between the support flange 8 and the inner diameter portion 2a of the filter body 2 is defined by the filter body 2 and the rim ( It is sufficient that a gap does not occur between 3a and 3b).
이와 같은 구성의 본 고안 마이크로 필터는 도입포오트(6) 측으로부터 여과될 유도체가 유입되어 필터체(2)를 통해 미세여과된 뒤 필터체(2)의 내경부(2a)로 유입되고, 여과된 유동체는 도출포오트(7)를 통해 외부로 유출되도록 작동한다.The micro filter of the present invention having such a configuration is introduced with a derivative to be filtered from the inlet port 6 side, microfiltered through the filter body 2, and then introduced into the inner diameter portion 2a of the filter body 2, and filtered. The fluid flows to the outside through the discharge port (7).
본 고안 마이크로 필터는 상술한 바와 같이 중심축(4)에 형성된 복수의 지지플랜지(8)에 의해 필터체(2)가 정확히 위치한 상태에서 조립될수 있고 사용중 충격등에 의해 필터체(2)가 정위치로부터 이탈하는 일이 없이 확실히 지지되므로 종래와 같이 미세여과가 이뤄지지 않는등의 불량이 발생하지 않는 매우 유용한 고안인 것이다.The micro filter of the present invention can be assembled in a state where the filter body 2 is precisely positioned by the plurality of support flanges 8 formed on the central shaft 4 as described above, and the filter body 2 is in the correct position due to impact during use. It is a very useful design that does not cause defects such as microfiltration not achieved as it is supported without deviating from it.
