본 발명은 용접흄 집진기에 관한 것으로, 더욱 상세하게는 필터를 2중구조로 구성하여 용접흄 집진 효율을 향상시키고, 집진용 필터에 쌓인 용접흄을 효과적으로 떨어내도록 하여 용접흄 집진기의 수명을 연장하기 위한 것이다.The present invention relates to a welding fume dust collector, and more particularly, to improve the welding fume dust collecting efficiency by configuring the filter in a double structure, and to effectively reduce the welding fume accumulated in the filter for dust collecting to extend the life of the welding fume dust collector.

주지하다시피, 용접과정에서는 눈에 보이지 않을 정도로 미세한 크기의 용접 흄이 발생되어 공기중에 부유하게 되므로 이를 그대로 들이마실 경우 중금속 오염, 진폐증과 같은 질병에 걸릴 수 있으므로 이를 용접흄 집진기를 통해 집진하여 주고 있다.As it is well known, welding fume of minute size is invisible in the welding process and floats in the air, so if you inhale it, you may get diseases such as heavy metal contamination and pneumoconiosis. .

이러한 용접흄 집진기는 통상 필터의 후위에 집진용 모터를 구비하여 공기를 흡입·배출하는 과정에서 용접흄이 필터에 의해 집진되면서 깨끗한 공기만을 배출하도록 되어 있으며, 필터에 쌓인 용접흄은 에어를 분사하여 주기적으로 떨어 하부의 배출서랍에 의해 외부로 배출·폐기하도록 되어 있다.These welding fume dust collectors are usually provided with a motor for dust collection at the rear of the filter, and in the process of suctioning and discharging air, the welding fume is collected by the filter so that only clean air is discharged. It is to be discharged and disposed of outside by the discharge drawer at the bottom.

즉, 용접흄 집진기에는 원통형의 필터가 적용되고, 이러한 원통형의 필터 일측 입구측에 에어노즐이 위치되며, 에어노즐과 연결되어 있는 에어관상에는 솔레노이드 밸브가 개재되어 솔레노이드 밸브를 주기적으로 열어주게 되면 에어노즐의 선단으로부터 압축공기가 일정한 각도로 벌어지면서 분사되어 원통형 필터의 안쪽을 타격해줌으로써 필터 외측에 쌓여있던 용접흄을 떨어주게 되며, 용접흄은 자중에 의해 하부의 배출서랍에 쌓이게 되어 이를 배출·제거하는 것이다.That is, a cylindrical filter is applied to the weld fume dust collector, and an air nozzle is positioned at the inlet side of the cylindrical filter, and a solenoid valve is interposed on the air pipe connected to the air nozzle to periodically open the solenoid valve. Compressed air is ejected at a certain angle from the tip of the blower and blows to the inside of the cylindrical filter to drop the welding fume accumulated on the outside of the filter, and the welding fume accumulates in the lower discharge drawer by its own weight to discharge and remove it. .

그러나, 이러한 일반적인 용접흄 집진기의 탈진장치는 에어노즐을 통해 분사되는 압축공기가 원통형 필터의 안쪽에 비스듬히 입사하게 되므로 에어노즐로부터 거리가 멀어질수록 압축공기에 의해 타격해주는 강도가 현저히 떨어지게 되어 전체적으로 용접흄의 탈진효율이 떨어지고, 특히 에어노즐로부터 먼 거리에 있는 부위는 용접흄이 떨어지지 않고 계속 쌓이게 되어 결국 필터를 조금만 사용하여도 교체해주어야 하는 문제가 있었다.However, in the dust extraction apparatus of the general welding fume dust collector, the compressed air injected through the air nozzle is obliquely incident on the inside of the cylindrical filter, so that the distance from the air nozzle is significantly lowered and the strength of the welding fume is significantly reduced. Dedusting efficiency is reduced, especially the part far away from the air nozzle is a continuous accumulation of welding fume does not fall and eventually had to replace the filter using a little.

또한, 일반적인 용접흄 집진기에는 필터가 하나만 적용되어 있어 용접흄의 입자크기에 상관없이 모든 용접흄이 하나의 필터에 의해 걸러지게 되므로 필터의 수명을 떨어뜨리는 원인이 되고 있다.In addition, since only one filter is applied to a general welding fume dust collector, all welding fumes are filtered by one filter regardless of the particle size of the welding fume, which causes a decrease in the life of the filter.

본 발명은 이러한 점을 감안하여 제안된 것으로, 평판형 필터는 공기유입측에 설치하고, 원통형 필터는 장치 안쪽에 설치하여 전체적으로 2중 필터구조를 갖도록 하되, 에어관을 원통형 필터의 안쪽까지 연장하여 여기에 직각향상으로 절곡되어 있는 에어노즐을 그 선단부가 원통형 필터의 중앙을 향하도록 고정함으로써 에어노즐이 돌아가면서 원통형 필터를 전체적으로 균일하게 타격하도록 하여 용접흄의 탈진효율을 높이도록 함은 물론 이를 통해 필터의 수명을 연장할 수 있는 용접흄 집진기를 제공하고자 하는 것이다.The present invention has been proposed in view of such a point, and the flat filter is installed on the air inlet side, and the cylindrical filter is installed inside the apparatus to have a double filter structure as a whole, by extending the air pipe to the inside of the cylindrical filter. By fixing the air nozzles bent at right angles to the center of the cylindrical filter, the air nozzle rotates to uniformly strike the cylindrical filter as a whole, thereby increasing the dust removal efficiency of the welding fume and of course the filter. To provide a weld fume dust collector that can extend the life of the.

이와 같이 구성된 본 발명에 따른 용접흄 집진장치는 다음과 같은 작용을 한다.Welding fume dust collector according to the present invention configured as described above has the following functions.

먼저, 용접을 할 때 발생되는 용접흄은 공기중에 부유하기 때문에 육안으로는 보이지 않지만 들이마시게 되면 중금속 오염, 진폐증과 같은 인체에 매우 안좋은 질병을 일으키게 되므로 용접흄 집진기를 사용하여 주기적으로 공기중에 포함되어 있는 용접흄을 집진, 탈진, 포집, 배출하고 있음은 주지의 사실이다.First, the welding fume generated during welding is not visible to the naked eye because it is suspended in the air, but if inhaled, it causes very bad diseases such as heavy metal contamination and pneumoconiosis. It is well known that the welding fume is collected, exhausted, collected and discharged.

이때, 필터에 쌓인 용접흄을 효율적으로 떨어주는 것에 따라 용접흄의 집진 효율이 향상되고, 필터의 수명, 나아가 용접흄 집진기 전체의 수명이 연장될 수 있음은 자명하다.At this time, by effectively dropping the welding fume accumulated in the filter it is obvious that the collection efficiency of the welding fume can be improved, the life of the filter, and further, the life of the entire welding fume dust collector can be extended.

본 발명에 따른 용접흄 집진기를 가동하게 되면 집진모터(102)에 의해 공기가 강제로 하우징(101)의 안쪽공간으로 흡입되는데, 하우징(101)의 공기 유입측에는 평판형 필터(110)가 형성되어 있어 입자가 큰 용접흄 또는 이물질은 이러한 평판형 필터(110)에 의해 걸러지게 되며, 입자가 미세한 용접흄은 평판형 필터(110)를 빠져나가 안쪽으로 유입된다. 이때, 평판형 필터(110)는 일반적인 필터부재(111) 단독으로 구성될 수도 있고, 철재로 이루어진 필터부재(111)의 사이사이에 자석(112)이 구비되어 이루어질 수도 있는 것이므로 전자의 경우 용접흄을 입자의 크기에 따라 걸러주는 역할을 수행할 수 있고, 후자의 경우 필터부재(111)가 자석(112)에 의해 모두 자화되어 철재인 용접흄을 보다 효율적으로 걸러줄 수 있다.When the welding fume dust collector according to the present invention is operated, air is forcibly sucked into the inner space of the housing 101 by the dust collecting motor 102, and the flat filter 110 is formed on the air inlet side of the housing 101. The large welding fume or foreign matter is filtered by the flat filter 110, and the fine welding fume leaves the flat filter 110 and flows inward. In this case, the flat plate filter 110 may be composed of a general filter member 111 alone, or the magnet 112 may be provided between the filter members 111 made of steel. In the latter case, the filter member 111 may be magnetized by the magnets 112 to more efficiently filter the welding fume which is steel.

평판형 필터(110)를 통과하여 하우징(101)의 내부로 유입된 미세한 크기의 용접흄은 원통형 필터(120)에 의해 걸러져 그 표면에 쌓이게 되고, 깨끗한 공기만 원통형 필터(120)를 빠져나가 외부로 배출된다.The fine weld fume introduced into the housing 101 through the flat filter 110 is filtered by the cylindrical filter 120 and accumulated on the surface thereof, and only clean air exits the cylindrical filter 120 to the outside. Discharged.

이때, 원통형 필터(120)의 안쪽까지 에어관(103)이 연장되어 그 자유단에 직각형상의 에어노즐(130)이 원통형 필터(120)의 중앙부를 향해 회전가능하게 설치되어 있고, 이러한 에어노즐(130)에 구동모터(140)의 축(141)이 기어방식 또는 벨트방식과 같이 동력전달가능하게 연결되어 있으므로 에어관(103)상에 장착되어 있는 솔레노이드 밸브(160)를 개방하게 되면 압축공기가 에어관(103)을 통해 에어노즐(130)로 전달되고, 에어노즐(130)의 선단부를 통해 일정한 각도로 분사되어 원통형 필터(120)이 안쪽을 타격하게 되며, 이와 동시에 구동모터(140)가 구동하여 에어노즐(130)이 360°회전하게 되므로 상기 분사되는 공기는 구동모터(140)가 구동하는 동안 지속적으로 원통형 필터(120)의 안쪽 모든 부위를 순차적으로 타격해줄 수 있음은 물론 에어노즐(130)을 통한 입사각이 크고 전체적으로 균일하므로 압축공기를 통한 타격력 역시 원통형 필터(120) 전체적으로 커지게 됨으로써 원통형 필터(120) 표면에 쌓인 용접흄을 보다 양호하게 떨어낼 수 있는 것이다.At this time, the air pipe 103 is extended to the inner side of the cylindrical filter 120, the right angled air nozzle 130 is installed rotatably toward the central portion of the cylindrical filter 120, such an air nozzle Since the shaft 141 of the drive motor 140 is connected to the power transmission method such as a gear method or a belt method to the 130, when the solenoid valve 160 mounted on the air pipe 103 is opened, the compressed air Is transmitted to the air nozzle 130 through the air pipe 103, is injected at a predetermined angle through the front end of the air nozzle 130, the cylindrical filter 120 hits the inside, and at the same time the drive motor 140 Since the air nozzle 130 is rotated by 360 ° to drive the injected air can continuously hit all the inner portion of the cylindrical filter 120 sequentially while the drive motor 140 is driven, as well as the air nozzle The angle of incidence through 130 And overall impact force through uniform, so the compressed air also increases by being generally cylindrical filter 120 that can be dropped and more preferably a Welding Fume stacked on the surface of the cylindrical filter 120.

이상에서 설명한 바와 같이, 본 발명은 용접흄 집진기에 평판형 필터와 원통형 필터를 동시에 적용함으로써 용접흄의 집진 효율을 높일 수 있으며, 원통형 필터의 내부 중앙에 회전가능한 에어노즐을 위치시켜 이를 회전시키면서 원통형 필터 전체적으로 균일하게 압축공기를 분사해주는 것이므로 탈진효율을 높일 수 있어 탈 진효율을 더욱 높일 수 있는 이점이 있는 것이다.As described above, the present invention can increase the dust collection efficiency of the welding fume by applying the flat filter and the cylindrical filter to the welding fume dust collector at the same time, the rotatable air nozzle in the center of the cylindrical filter to rotate the entire cylindrical filter Since uniformly spraying compressed air can increase the efficiency of dust extraction, there is an advantage that can further increase the dust efficiency.
