상기의 열악한 작업환경을 개선하기 위한 종래 기술의 일예가 도 1에서와 같이 개시 되었다.An example of the prior art for improving the poor working environment has been disclosed as in FIG.
즉, 안내프레임(3)에 가스공급호스(2)가 연결된 절단토오치(1)를 이동가능하게 설치하고, 하부측에 작업물이 놓이는 작업대(4)를 설치하되 그 하부에 절단작업시 파생되는 산화물 또는 스크랩을 수용하는 물이 담긴 박스(5)를 착설하였다.That is, the cutting torch (1) connected to the gas supply hose (2) is installed on the guide frame (3) to be movable, and the work table (4) on which the work is placed is installed on the lower side, but it is derived during the cutting work. The box 5 containing the water which receives the oxide or the scrap which was used was built.
그러나, 상기와 같은 종래의 절단방법은, 박스(5)에 담긴 물이 시간이 경과하면서 부패되어 주변환경을 악화시키게 되고, 절단된 금속편 등이 박스(5) 속의 물에 잠기면서 부식이 발생되어 금속편 잔재물의 재활용이 적절하지 못한 등의 결점이 있었다.However, in the conventional cutting method as described above, the water contained in the box 5 decays over time to deteriorate the surrounding environment, and the cut metal pieces are immersed in the water in the box 5 to cause corrosion. There were drawbacks such as inadequate recycling of scrap metal residues.
또한 상기 방법은 절단 잔재물을 자중에 의해 박스에 낙하 및 수용되게 한 것이므로, 분말상의 쇳가루 및 비산되는 절삭물은 물론 작업자의 호흡기를 통해 흡입될 수도 있는 유독성 연무 등은 제거가 전혀 불가능한 문제점이 있었다.In addition, since the method is to drop and accommodate the cutting residue in the box by its own weight, the powdery powder and scattered cuttings, as well as the toxic fumes that may be sucked through the respiratory tract of the worker had a problem that can not be removed at all.
본 고안은 위와 같은 금속재의 절단시 발생되는 종래기술의 문제점을 감안하여 안출한 것으로서, 그 목적은 절단토오치를 이용하여 금속재를 절단할 때 파생되는 금속편 잔재물은 물론 분진 및 유독성 연무를 최소화 할 수 있는 가스절단기의 오염물 제거장치를 제공함에 있다.The present invention has been devised in view of the problems of the prior art generated when cutting the above metal materials, the purpose is to minimize the dust and toxic fumes as well as the residues of metal pieces derived when cutting the metal materials using the cutting torch. The present invention provides a contaminant removal device of a gas cutter.
이러한 목적을 달성하기 위한 본 고안은, 절단이 이루어지는 작업대의 지지면에 하향으로 물을 분사시키는 냉각파이프를 배관하여 강제로 물을 공급·분사 시키되 분사된 물은 절단 잔재물이 수용되는 박스에 동시에 회수되게 한 상태에서 냉각파이프로 재공급하여 순환되게하고, 절단토오치의 일측에 집진창지에 연결된 흡입구를 취부하여 분진 및 연무를 포집하게 됨으로써 절단잔재물을 샤워 방식으로 제거하는 한편 제거가 미흡한 미세분진이나 연무 등은 집진장치의 흡입작용에 의해 강제로 포집·제거하여 작업자의 건강 유지는 물론 작업환경을 개선하게 됨을 특징으로 한다.The present invention for achieving the above object, by forcing the cooling pipe for spraying water downward to the support surface of the workbench to be cut, forcibly supplying and spraying the water, but the sprayed water is simultaneously recovered in a box containing the cutting residue In this state, recirculation is carried out by cooling pipe to circulate, and suction inlet connected to the dust collecting window is collected at one side of the cutting torch to collect dust and mist, so that the cutting residue is removed by a shower method while fine dust or The fumes are forcibly collected and removed by the suction action of the dust collecting device to maintain the health of the worker and improve the working environment.
