이러한 구성으로 이루어진 본 발명은 다음과 같은 작동관계를 갖는다.The present invention made up of such a configuration has the following operational relationship.

먼저, 집진과정이 수행되면서 백(10)의 외주면에 더스트가 부착되게 되면 주기적으로 혹은 선택에 의해 고압의 공기를 백(10)의 상부로부터 공급하여(즉, 역류시켜) 부착된 더스트를 떨어내게 된다.First, when dust is attached to the outer circumferential surface of the bag 10 while the dust collecting process is performed, the high pressure air is supplied from the upper part of the bag 10 periodically (or countercurrently) to drop the attached dust. do.

즉, 백(20)의 세정을 위해 공급된 에어는 벤츄리관(30)을 통해 분사되면서 에어분배관(40)을 통해 분배되게 된다.That is, the air supplied for cleaning the bag 20 is injected through the air vent pipe 40 while being injected through the venturi pipe 30.

이때, 에어분배관(40)의 상단에서부터 하단에 걸쳐 형성된 분사공(44a~e)은 크기가 달리 형성되어 있으므로 배출되어 에어의 양은 일정하게 유지되게 된다.At this time, since the injection holes 44a to e formed from the upper end to the lower end of the air distribution pipe 40 are formed in different sizes, the amount of air is kept constant.

각 분사공(44a~e)을 통해 에어가 분사되면서 이들 분사공(44a~e)을 막고 있던 타격판(50)이 상승되면서 백(10)의 내주면을 순간적으로 치면서 접촉충격을 가하게 되고, 이로 인해 백(10)의 외주면에 부착되어 있던 더스트가 떨어지게 되며, 또한 동시에 분출된 에어가 백(10) 내부에서 외부로 분사되게 되므로 충격에 의해 떨어지려고 하던 더스트마저 완전히 백(10)의 외주면으로부터 탈거되게 된다.As the air is injected through each of the injection holes 44a to e, the impact plate 50 which blocks the injection holes 44a to e is raised, and a contact shock is applied to the inner peripheral surface of the bag 10 instantaneously. Due to this, dust attached to the outer circumferential surface of the bag 10 falls, and at the same time, the ejected air is ejected from the inside of the bag 10 to the outside, so even the dust that was about to be dropped by the impact is completely removed from the outer circumferential surface of the bag 10. Will be.

아울러, 에어분배관(40)을 타고 그 하단으로 공급된 에어는 상기 상승에어분사구(62)를 통해 분출되면서 그 압에 의해 상기 에어분배관(40)이 일정높이로 상승하게 되며, 동시에 회전에어분사구(64)를 통해 분사되는 분사압에 의해 상기 에어분배관(40)이 회전하게 된다.In addition, the air supplied to the lower end of the air distribution pipe 40 is ejected through the rising air injection port 62 while the air distribution pipe 40 is raised to a certain height by the pressure, at the same time rotating air The air distribution pipe 40 is rotated by the injection pressure injected through the injection port 64.

이때에는, 상기 에어분배관(40)이 상승되면서 핀(66)이 스토퍼(82)에 걸리지 않기 때문에 원활하게 회전될 수 있으며, 공급하는 에어의 스트로크(에어를 단속적으로 쏘아주는 것을 일컬음)에 의해 1회 세척시마다 90°씩 회전되도록 조절하여 백(10)의 전면을 따라 회전하면서 백(10)의 외주면 모두가 세정될 수 있도록 하여 줌이 바람직하다.At this time, since the air distribution pipe 40 is raised, the pin 66 is not caught by the stopper 82, so that it can be rotated smoothly, by the stroke of the air to be supplied (referred to as intermittently shooting the air). It is preferable to zoom so that all of the outer circumferential surface of the bag 10 can be cleaned while rotating it along the front surface of the bag 10 by adjusting it to rotate by 90 ° every single wash.

즉, 도 7의 (가),(나),(다)에서와 같이 작동된다.That is, it operates as in (a), (b) and (c) of FIG.

본 발명에 따르면, 집진설비의 백필터 세정 작업시 에어가 한곳에 집중되지 않고 골고루 분산되게 되어 백의 조기 손상을 방지하고, 또한 백 전체를 골고루 세정하게 됨으로서 백의 세정능률을 향상시킬 수 있게 된다.According to the present invention, during the bag filter cleaning operation of the dust collector, the air is dispersed evenly without being concentrated in one place, thereby preventing premature damage to the bag, and also cleaning the entire bag evenly, thereby improving the cleaning efficiency of the bag.
