본 고안은 강판을 소막형상으로 절단하는데 사용하는 플라즈마 아크 절단기에 설치하여 절단시에 발생하는 분진, 연기등 유해기체를 작업장의 밖으로 배출하는 플라즈마 아크절단기의 배연장치에 관한 것이다.The present invention relates to a plasma arc cutting machine for installing a plasma arc cutting machine used to cut a steel plate into a small film shape to discharge harmful gases such as dust and smoke generated during cutting out of the workplace.

종래 플라즈마 아크절단기는 강판을 소망형상으로 절단함에 있어서 일반적인 불꽃절단기보다 절단속도가 빠르고 절단기능이 우수하여 품질을 향상시키는 효과로 인해 최근에 많이 사용되고 있는 실정이다.Conventional plasma arc cutting machine is a situation that has been used in recent years due to the effect of improving the quality of the cutting speed is faster and excellent cutting function than the general flame cutter in cutting the steel plate in the desired shape.

그러나 플라즈마 아크절단기는 상술된 바와 같이 불꽃절단기에 비해 기능상 우수한 장점이 있는 반면에 절단시에 다량의 분진과 연기등 유해 기체가 발생하여 주위의 공기오염을 가속화시키므로 작업환경이 현저하게 악화되어 작업자와 주위의 다른 작업자에게까지 건강을 해치기 때문에 플라즈마 아크절단기에는 이러한 유해가스를 배출하는 배연장치가 필수불가결한 것이었다.Plasma arc cutters, however, have superior functional advantages over flame cutters as described above, while hazardous gases such as large amounts of dust and smoke are generated during cutting, accelerating ambient air pollution, which significantly deteriorates the working environment. Plasma arc cutters were indispensable for the exhaust gas to emit these harmful gases, because they also harm other workers around them.

알려진 플라즈마 아크절단기의 배연장치는 절단기본체에 집진장치를 탑재하여 분진을 제거하는 방식과 집진장치로 별도로 설치하여 분진을 집진하는 방식이 있으나, 전자는 장비에 집진설비를 탑재하여 사용하므로 공간의 활용도는 좋으나 집진기의 용량을 증대하는데는 한계가 있고 후자는 집진기의 용량을 얼마든지 증대할 수 있는 장점은 있으나 장비의 설치시 많은 공간과 정반제작비용이 많이 드는 폐단이 있었다.Known plasma arc cutters are equipped with dust collectors on the cutter body to remove dust and dust collectors by separately installed dust collectors. Although it is good, there is a limit to increase the capacity of the dust collector and the latter has the advantage of increasing the capacity of the dust collector, but there was a lot of space and the cost of producing the surface plate when installing the equipment.

본 고안은 이와 같은 점을 감안하여 안출한 것으로 플라즈마 절단기와 동일하게 구동을 하는 절단정반의 하부에 배연후드를 설치하여 절단 토오치의 이동시에 동일하게 이동하면서 절단시 발생하는 분진을 흡수하여 별도로 설치된 집진기로 이동 제거하므로서 분진을 가장 효율적으로 제거 할 수 있게 한 것인데 이를 첨부도면에 의거 상술하면 다음과 같다.The present invention has been devised in view of the above, and the exhaust fume hood is installed at the lower part of the cutting table which drives the same as the plasma cutting machine, so that the dust is generated during cutting while moving the same during the movement of the cutting torch. By removing and moving to the dust collector, it is possible to remove dust most efficiently. This will be described in detail based on the accompanying drawings as follows.

플라즈마 절단기본체(1)의 하부에 격자상의 절단정반(2)을 레일(3)위에 설치한 것에 있어서 절단정반(2)의 저부에 절단정반 폭과 동일한 길이로서 절단기본체(1)에 동조하여 이동하는 배연후드(4)를 절단기본체(1)의 레일(3)보다 길게 형성한 레일(3')상에 설치하고 배연후드(4)의 내부에는 ∧자 형상의 유도판(5)을 지지간(6)에 의해 이격 설치하여 절단정반(2)으로부터 배출되는 유해기체를 배연후드(4)의 일측에 설치된 공기노즐(7)로부터 급기되는 공기와 함께 배연후드(4)의 저면중간에 연결한 유선형 배출관(80으로 배출되게 하되 배출관(8)의 단부를 ∪자 형상으로 절곡하여 지하에 절단기본체(1)에 대응하는 길이로서 지하에 매설된 물탱크타입의 메인덕트(9)에 설치하여서 되는 것이다.In the case where the lattice-shaped cutting plate 2 is provided on the rail 3 at the lower part of the plasma cutting machine body 1, the bottom of the cutting plate 2 is synchronized with the cutting body 1 at the same length as the cutting plate width. The flue gas hood 4 is installed on the rail 3 'formed longer than the rail 3 of the cutter body 1, and the U-shaped guide plate 5 is supported inside the flue gas hood 4. (6) is connected to the middle of the bottom surface of the flue hood (4) together with the air supplied from the air nozzle (7) installed on one side of the flue hood (4) by separating the harmful gas discharged from the cutting plate (2). It is to be discharged to the streamlined discharge pipe (80), but the end of the discharge pipe (8) is bent in a U-shape to be installed in the main duct (9) of the water tank type embedded in the basement as a length corresponding to the cutter body (1) underground will be.

이와같이된 본 고안은 절단정반(2)상에 피절단제를 재치하고 플라즈마 절단기본체(1)가 레일(3)위를 활주하면서 토오치에 의해 피절단재를 절단하게 되는데 절단정반(2)의 저부에는 ∨자형상의 유도판(5)이 설치된 배연후드(4)가 절단기본체(1)와 동조하여 이동하도록 설치되어 있고 배연후드(4)의 저부에 연결된 유선형 배출관(8)의 ∪자형 단부가 지하에 매설된 메인덕트(9)에 삽입되어 있으므로 절단기본체(1)가 이동하면 배연후드(4)도 동시에 이동되고 또한, 배출관(8)도 절단기본체(1)와 대응하는 길이로서 지하에 매설된 메인덕트(9)를 따라 이동하게 된다.According to the present invention, the cutting material is placed on the cutting table 2 and the plasma cutting body 1 slides on the rail 3 to cut the cutting material by the torch. At the bottom, a fume hood (4) having a U-shaped guide plate (5) is installed to move in synchronization with the cutter body (1), and the U-shaped end of the streamlined discharge pipe (8) connected to the bottom of the fume hood (4) Since the main body (9) buried underground is inserted, when the main body (1) moves, the flue gas hood (4) moves at the same time, and the discharge pipe (8) is also buried underground with a length corresponding to the main body (1). The main duct 9 is moved along.

따라서 절단정반(2)위에서 절단기본체(1)의 토오치에 의해 절단작업이 이루어지면 이때 발생된 유해기체는 배연후드(4)의 유도판(5)에 의해 제1도와 같이 유도판(5)의 저부로 유도되어 중간에 설치된 배출관(8)을 통해 메인덕트(9)로 배출되어 집진기(미도시)에 의거 집진된다.Therefore, when the cutting operation is performed by the torch of the cutter body 1 on the cutting plate 2, the harmful gas generated at this time is guided by the guide plate 5 of the exhaust hood 4 as shown in FIG. Guided to the bottom of the discharge through the discharge pipe 8 is installed in the main duct (9) is collected by a dust collector (not shown).

이때 배연후드(4)에는 일측에 공기노즐(70이 설치되어 공기가 강한압력으로 배연후드(4)의 내부로 배출되고 있으므로 절단정반(2)에서 발생된 유해기체는 공기노즐(7)의 공기와 함께 혼합되어 강한 힘으로 유도판(5) 저부의 배출관(8)으로 배출됨에 따라 유해가스의 배연 효과가 매우 크다.At this time, since the air nozzle 70 is installed at one side of the exhaust fume hood 4 and the air is discharged into the exhaust fume hood 4 under a strong pressure, the harmful gas generated at the cutting surface plate 2 is the air of the air nozzle 7. As it is mixed with and discharged into the discharge pipe (8) at the bottom of the guide plate (5) with a strong force, the exhaust gas of the harmful gas is very large.

여기서 메인덕트(9)에 설치되어 이를 따라 이동하는 배출관(8)은 유도체의 저항을 감소시킬 수 있는 유선형으로 형성되어 있으므로 메인덕트(9)를 따라 이동시, 유체의 저항을 적게 받아 배연후드의 이동을 용이하며 또한 배연후드(4)의 레일(3')은 절단기본체(1)가 이동하는 레일(3)보다 상대적으로 길게 형성되어 있으므로 배연후드(4)가 절단정반(2)의 밖으로 빠져나올 수 있어 청소나 수리등 정비를 쉽게 할 수 있는 잇점이 있다.Here, the discharge pipe 8 installed in the main duct 9 and moving along it is formed in a streamlined shape to reduce the resistance of the inductor. Therefore, when moving along the main duct 9, the flue gas receives less resistance from the fluid. In addition, since the rail 3 'of the fume hood 4 is formed to be relatively longer than the rail 3 to which the cutter body 1 moves, the fume hood 4 will come out of the cutting surface 2. There is advantage that we can easily perform maintenance such as cleaning or repair.

이와 같이 본 고안은 배연후드에 의한 배연효과가 종래의 같은 용량의 집진기보다 상대적으로 매우 커 작업장내의 공기오염을 방지하고 작업환경을 좋게하는등의 효과가 매우 크다.As such, the present invention has a great effect such as preventing the pollution of air in the workplace and improving the working environment because the smoke effect by the fume hood is relatively much larger than that of the conventional dust collector of the same capacity.
