본 고안은 고온의 열풍을 필요로 하는 공업용 건조장치등에 사용할 수 있게 고안된 간접 열풍방식의 열풍기에 대한 것이다.The present invention is directed to a hot air fan of the indirect hot air system designed to be used in industrial drying equipment requiring high temperature hot air.

종래의 산업용 간접 열풍기나 대용량의 온풍난방기들은 통상내부로는 공기를 외부로는 연소열을 흐르게 하는 연관식 방식이거나, 외부에는 공기를 내부에는 연소열을 흐르게 하는 공관식 방식으로 구성된 것인데, 이들은 그 크기에 비하여 전열면적이 작고 또 연소통을 내화벽돌로 감싸주었기 때문에 열교환율이 감소되는 결점이 있었으며, 이에 따라 열교환효율을 높이기 위해서는 연소통을 크게 해야 되는 문제점이 있었고, 가열과 냉각의 반복으로 인한 균열등이 발생함에 따라 연소통의 내구성에도 큰 문제점이 있었다.Conventional industrial indirect hot air heaters or large-scale hot air heaters are generally configured in a cascaded manner in which air flows to the outside and combustion heat flows to the outside, or in a conduit type manner in which air flows to the outside. Compared to this, the heat transfer area is small and the combustion cylinder is wrapped in fire brick, which results in a decrease in heat exchange rate. Accordingly, in order to increase the heat exchange efficiency, the combustion cylinder needs to be enlarged. As this occurred, there was a big problem in the durability of the combustion cylinder.

본 고안은 이러한 점들을 해결하기 위하여 고안한 것으로서, 연소통의 상부에 설치하는 열교환통에 다수의 공기가 열관을 관통되게 착설하고, 또 연소통의 외주면을 적정 간격으로 격리되는 상태로 감싸주게 공기유도관을 설치하므로 전체크기를 작게 하면서도 전열면적을 증대시키고 1, 2차 가열된 공기가 연소통 외주면을 통과할때는 빠른 속도로 통과하게 됨과 동시에 가열된 연소통으로 부터도 열을 흡수하여 더욱 가열되게 하였기 때문에 열교환효율의 향상과 연소통의 과열도 방지하여 주므로 내구성을 증대시켜 줄 수도 있도록 한 것이다.The present invention has been devised to solve these problems, and air is installed in a heat exchanger tube installed in the upper part of the combustion tube so that a plurality of air penetrates the heat pipe, and surrounds the outer circumferential surface of the combustion cylinder in an insulated state at appropriate intervals. By installing the induction pipe, the overall size is reduced while increasing the heat transfer area, and when the first and second heated air passes through the outer circumference of the combustion cylinder, it passes at a high speed and absorbs heat from the heated combustion cylinder to make it more heated. Therefore, it improves heat exchange efficiency and prevents overheating of the combustion cylinder, thereby increasing durability.

이하, 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

내벽(11)과 외벽(12) 사이에는 단열재(13)를 충진하고 정면상측에는 공기주입구(14)를 그 하측에는 화염구(15)를, 또 이 화염구의 반대측면에는 열풍유출구(16)를 각각 형성한 기체(1)의 내부는 격리판(2)으로 열교환실(3)과 연소실(4)이 상하로 격리형성되게 하되 이들의 정면측은 서로 통하게 하였고, 상기 열교환실에는 열교환통(3')을, 연소실에는 연소통(4')을 각각 고정 설치함과 동시에 이들 통체들은 그 저면과 상면 중간을 연결통로(5)에 의해 서로 통하게 연결하였으며, 상기 열교환통(3')의 상면 중간에는 배기관(6)을 착설하였고, 연소통(4')의 정면에는 화염구(15)를 연결하였다.A heat insulator 13 is filled between the inner wall 11 and the outer wall 12, an air inlet 14 is provided on the front side, a flame opening 15 is provided on the lower side thereof, and a hot air outlet 16 is provided on the opposite side of the flame opening. The inside of each formed gas 1 is separated from the heat exchange chamber 3 and the combustion chamber 4 by the separator 2, and the front side thereof is in communication with each other, and the heat exchange chamber 3 ' ) And the combustion cylinder 4 'is fixedly installed in the combustion chamber, and these cylinders are connected to each other by a connecting passage 5 between the bottom and the upper surface thereof, and in the middle of the upper surface of the heat exchange cylinder 3'. The exhaust pipe 6 was installed, and the flame opening 15 was connected to the front of the combustion cylinder 4 '.

한편, 상기 열교환통에는 다수의 공기가 열관(31)들을 이 열교환통을 전후로 관통하게 착설하고, 또 공기주입구(14)의 하단으로 부터 상기 열교환통의 외벽과 기체(1)의 내벽(11)사이의 정면과 양측면부만 차단판(32)으로 차단시켜 열교환실(3)을 상하격실(3a)(3b)로 격리되게 함과 동시에 배면부는 서로 통하게 하였다.On the other hand, a plurality of air is installed in the heat exchange cylinder so that the heat pipes 31 pass through the heat exchange cylinder back and forth, and the outer wall of the heat exchange cylinder and the inner wall 11 of the gas 1 from the lower end of the air inlet 14. Only the front and both side portions therebetween were blocked by the blocking plate 32 so as to isolate the heat exchange chamber 3 into the upper and lower compartments 3a and 3b, and at the same time, the rear portions communicated with each other.

또한, 연소통(4')의 외주면은 이 연소통보다 직경이 큰 공기유도관(7)을 수개의 고정편(71)과 지지편(72)들로 고정설치하여 감싸주게 함과 동시에 이들 사이에는 직경 차이에 의한 공기유통로(73)가 빙둘러 형성되게 하였고, 상기 공기주입구(14)측에는 송풍기(8)를, 화염구(15)측에는 버어너(9)를 각각 설치하였다.In addition, the outer circumferential surface of the combustion cylinder 4 'fixes and encloses the air induction pipe 7 having a larger diameter than the combustion cylinder with several fixing pieces 71 and support pieces 72, and at the same time therebetween. In the air flow path (73) by the difference in diameter is formed round, the air inlet (14) side, the blower (8), the flame opening (15) side was installed burner (9), respectively.

이와같이 구성되는 본 고안은 기체(1)를 건조실등의 외부에 설치하고 열풍유출구(16)를 건조실에 연결시켜 사용하는 것으로 버어너(9)를 점화시켜 화염구(15)를 통해 연소통(4')내로 화염을 주입시켜 주면 이 연소통내에서 연소되면서 발생되는 고열이 연결통로(5)를 통해 열교환통(3')내로 들어가 상승되는 과정에서 이 열교환통은 물론 이 통내로 전후로 관통하게 다수 착설한 공기가열관(31)들을 가열시켜 주게 되는데, 이때 송풍기(8)를 동작시켜 공기주입구(14)측으로 공기를 강제 송풍시켜 주면 공기가 이 주입구를 통해 열교환실(3)내로 들어가서 차단판(32)에 의해 격리되는 상부격실(3a)측의 공기가열관(31)들 및 내벽(11)과 열교환통(3')의 상면과 양측면 사이의 통로를 통과하여 배면측으로 이동하는 과정에서 열교환작용이 진행되어 가열되며, 가열된 공기는 열교환실(3)의 배면측 통로를 따라 하향되어 이번에는 차단판(32)에 의해 격리된 하부격실(3b)측의 공기가열관(31)들 및 격리판(2)과 내벽(11), 열교환통(3')의 저면과 양측면 사이의 통로를 통과하여 하부격실(3b)의 정면측으로 이동하는 과정에서도 열교환 작용이 계속 진행되어 더욱 가열되는 것이다.The present invention configured as described above uses the gas 1 to be installed outside the drying chamber and the like, and connects the hot air outlet 16 to the drying chamber to ignite the burner 9 to burn the combustion cylinder 4 through the flame opening 15. When the flame is injected into '), the high heat generated by the combustion in the combustion cylinder enters the heat exchange cylinder 3' through the connecting passage 5 and ascends into the heat exchange cylinder as well as back and forth through the passage. The installed air heating tubes 31 are heated. At this time, by operating the blower 8 to forcibly blow air to the air inlet 14, air enters into the heat exchange chamber 3 through the inlet and blocks the plate ( Heat exchange in the process of moving to the rear side through the passage between the upper and side surfaces of the air heating tubes 31 and the inner wall 11 and the heat exchange tube 3 'of the upper compartment 3a, which is isolated by the upper compartment 3a. Is heated and heated ball Is lowered along the rear side passage of the heat exchange chamber 3 and this time the air heating tubes 31 and the separator 2 and the inner wall 11 of the lower compartment 3b side which are separated by the blocking plate 32. In the process of moving to the front side of the lower compartment 3b through the passage between the bottom and both side surfaces of the heat exchange tube 3 ', the heat exchange action continues to be further heated.

이러한 작용에 의해 가열되는 공기는 격리판(2)의 정면측을 통해 연소실(4) 정면으로 하향되어 이번에는 연소통(4')과 공기유도관(7)사이의 공기유통로(73) 및 연소실(4)의 공간부를 통해 배면측으로 이동하면서 가열된 연소통(4')으로 부터 열을 흡수하게 되므로 더욱 고열로 가열되어 열풍유출구(16)를 거쳐 건조실내로 공급되는 것이다.The air heated by this action is lowered toward the combustion chamber 4 through the front side of the separator 2, and this time, the air flow path 73 between the combustion cylinder 4 'and the air induction pipe 7 and Since it absorbs heat from the heated combustion cylinder 4 'while moving to the rear side through the space portion of the combustion chamber 4, it is heated to a higher temperature and is supplied to the drying chamber via the hot air outlet 16.

이와같이 사용되는 본 고안은 차단판(32) 및 격리판(2)에 의해 열교환실(3)과 연소실(4)내에 공기의 유통로가 "지그재그" 형태로 형성됨에 따라 송풍기(8)에 의해 강제 송풍되는 공기가 상기와 같은 유통로를 거치는 과정에서 충분한 열교환작용이 진행되어 열교환효율이 향상됨은 물론 공기유통로(73)를 통과할 때에는 이 통로의 좁은 공간에 의해 빠른 속도로 통과하게 되기 때문에 연소통(4')의 과열되지 않게 열을 신속하게 흡수 통과하는 작용도 하게 되어 연소통의 내구성도 향상시켜 주는 작용도 하는 것이다.The present invention used in this way is forced by the blower 8 as the flow path of the air in the heat exchange chamber 3 and the combustion chamber 4 is formed in a "zigzag" form by the blocking plate 32 and the separator 2. In the process of passing through the air flow path as described above, sufficient heat exchange action is performed to improve heat exchange efficiency, and when passing through the air flow path 73, because it passes at a high speed by the narrow space of the passage. It also acts to rapidly absorb and pass heat without overheating the communication (4 '), which also improves the durability of the combustion cylinder.

이와같이 본 고안은 열교환효율이 좋고, 또 연소통의 내구성도 향상되며, 이에 따라 열풍기 자체를 크게 제작하지 않아도 되는등 매우 실용적인 고안이다.In this way, the present invention has a good heat exchange efficiency, and also improves the durability of the combustion cylinder. Accordingly, the present invention does not require the manufacture of the hot air blower itself.
