Description
본 고안은 라디언트튜브(Radiant Tube)에 관한 것으로, 특히 직관의 외주면에 나선형의 발열판을 형성시키고, 직관에 나선형의 가이드를 내장시킴으로써 주위로의 열발산을 극대화하고, 직관과 곡관의 열변형을 최소화할 수 있는 라디언트튜브(Radiant Tube)에 관한 것이다.The present invention relates to a radiant tube, in particular, by forming a spiral heating plate on the outer circumferential surface of the straight pipe, and by incorporating a spiral guide in the straight pipe to maximize the heat dissipation to the surroundings, and the heat deformation of the straight pipe and curved pipe It is about radiant tubes that can be minimized.
종래의 라디언트튜브는 도1 내지 도3에 도시한 바와같이 원통관으로 형성되면서 직관(8)의 외주면에 축방향의 4개의 지지대(6)가 원주방향으로 배열된 상태로 환형링(7)에 의해 고정되어 있다.Conventional radiant tube is formed in a cylindrical tube, as shown in Figures 1 to 3, the annular ring (7) in the state in which the four support (6) in the axial direction is arranged in the circumferential direction on the outer peripheral surface of the straight pipe (8) It is fixed by.
이러한 종래의 라디언트튜브는 내주면을 따라 고온의 가스가 직선적으로 흐르기 때문에 주위로의 열전달 효과가 미미하고, 이로써 고온의 가스에 의해 자유단의 곡관(5)에서 열변형이 발생되고, 이로 인해 수명이 단축되는 등의 문제점이 발생된다.In the conventional radiant tube, since the hot gas flows linearly along the inner circumferential surface, the heat transfer effect to the surroundings is insignificant, whereby heat deformation is generated in the curved pipe 5 at the free end by the hot gas, thereby resulting in a lifetime. This shortens the problem.
본 고안은 직관의 외주면에 나선형의 발열판을 형성시키고, 직관에 나선형의 가이드를 내장시킴으로써 주위로의 열발산을 극대화하고, 직관과 곡관의 열변형을 최소화할 수 있는 라디언트튜브(Radiant Tube)를 제공한다.The present invention forms a radiant heating plate on the outer circumferential surface of the straight pipe, and maximizes heat dissipation to the surroundings by embedding a spiral guide in the straight pipe, and minimizes the heat dissipation of the straight pipe and the curved pipe. to provide.

상기한 목적을 달성하기 위하여 본 고안은 라디언트튜브에 있어서, 직관의 외주면에 나선형으로 설치되는 발열판과; 상기 직관에 내장되면서 고온의 가스를 나선형으로 유도하는 가이드와; 중앙곡관과 튜브본체 사이에 설치되는 스프링으로 구성되는 것을 특징으로 하는 라디언트튜브를 제공한다.In order to achieve the above object, the present invention is a radiant tube, heating plate which is installed in a spiral on the outer peripheral surface of the straight pipe; A guide for spirally inducing hot gas while being embedded in the straight pipe; It provides a radiant tube, characterized in that consisting of a spring installed between the central curved tube and the tube body.
도면을 참조하여 본 고안의 구성 및 작용을 설명한다.With reference to the drawings will be described the configuration and operation of the subject innovation.
도4는 본 고안에 따른 라디언트튜브를 나타내는 개략도이다.Figure 4 is a schematic diagram showing a radiant tube according to the present invention.
본 고안에 따른 라디언트튜브는 직관(11)의 외주면 전체에 나선형의 발열판(15)이 용접되어 있다.In the radiant tube according to the present invention, a spiral heating plate 15 is welded to the entire outer circumferential surface of the straight pipe 11.
이때 발열판(15)은 외부공기와 접촉되는 직관의 면적을 늘려서 주위로의 열전달을 최대한 향상시키고, 직관의 강도를 증가시켜 직관의 수명을 연장할 수 있게 된다.At this time, the heating plate 15 can increase the area of the straight pipe in contact with the external air to improve the heat transfer to the surroundings, and increase the strength of the straight pipe can extend the life of the straight pipe.
여기서 라디언트튜브의 직관(11)만을 내열강재질로 원심주조에 의해 가공한 후, 그 외주면에 발열판(15)을 나선형으로 가공하거나, 나선형의 발열판(15)을 별도 제작하여 직관의 외주면에 용접하는 방법이 있다.Here, only the straight tube 11 of the radiant tube is processed by heat-resistant steel by centrifugal casting, and then the heating plate 15 is spirally processed on the outer circumferential surface thereof, or the spiral heating plate 15 is separately manufactured and welded to the outer circumferential surface of the straight tube. There is a way.
그리고 라디언트튜브의 직관(11)에는 내측 공간에 나선형의 가이드(14)가 설치되어 있다.In addition, a spiral guide 14 is provided in the inner tube 11 of the radiant tube.
상기 가이드(14)는 도시와 같이 그 양단이 각각 직관(11)의 상하단 내주면 일부에 용접고정되는 방식으로 고정될 수 있다.As illustrated, the guide 14 may be fixed in such a manner that both ends thereof are welded to a portion of the upper and lower inner circumferential surfaces of the straight pipe 11, respectively.
이는 직관(11)이 배설된 상태에서 이들을 연결하기 위해 곡관(16-1,16-2)이 용접되어 설치고정되므로 상기 곡관(16-1,16-2)이 용접되기전에 직관(11)의 상하단이 개방된 상태에서 미리 상기 가이드(14)를 삽입함과 동시에 그 양단을 각 직관(11)의 상하단측 내주면 일부에 용접고정하고, 이어 곡관(16-1,16-2)을 연결시킴으로써 간단히 설치할 수 있다.This is because the curved pipes 16-1 and 16-2 are welded and installed to connect them in a state in which the straight pipe 11 is disposed, so that the curved pipes 16-1 and 16-2 are welded to each other. The guide 14 is inserted in advance in the upper and lower ends, and both ends thereof are welded and fixed to a portion of the inner peripheral surface of the upper and lower ends of each straight pipe 11, and then the curved pipes 16-1 and 16-2 are simply connected. Can be installed.
이때 내열강 재질의 가이드(14)는 버너(10)에서 발생되는 고온의 가스가 나선형으로 회전되면서 직관(11)을 통과하게 유도함으로써 열발산 효과를 극대화하게 된다.At this time, the guide 14 of the heat-resistant steel material maximizes the heat dissipation effect by inducing the high temperature gas generated from the burner 10 to pass through the straight pipe 11 while spirally rotating.
한편 곡관(16-1,16-2)과 튜브본체(12) 사이에는 인장스프링(13)이 연결되어 직관(11)과 곡관(16-1,16-2)의 열변형을 흡수지지함으로써 열변형을 최소화할 수 있게 된다.On the other hand, a tension spring 13 is connected between the curved pipes 16-1 and 16-2 and the tube body 12 to absorb heat deformation of the straight pipe 11 and the curved pipes 16-1 and 16-2. Deformation can be minimized.
본 고안은 직관의 외주면에 나선형의 발열판을 형성시키고, 직관에 나선형의 가이드를 내장시킴으로써 주위로의 열발산을 극대화하고, 직관과 곡관의 열변형을 최소화할 수 있는 효과를 제공한다.The present invention forms an helical heating plate on the outer circumferential surface of the straight pipe, maximizes heat dissipation to the surroundings by embedding the spiral guide in the straight pipe, and provides an effect of minimizing heat deformation of the straight pipe and the curved pipe.
