본 고안은 전기도금시 발생되는 흄(Hume)처리장치에 관한 것으로서, 보다 상세하게는 흄처리를 위한 후드(Hood)의 막힘을 방지하여 흄적하(drop)에 의한 제품결함을 방지토록한 응축액 낙하방지용 흄후드에 관한 것이다.The present invention relates to a fume treatment device generated during electroplating, and more particularly, to prevent clogging of a hood for fume treatment to prevent product defects due to drop of condensate. It relates to a fume hood for prevention.

일반적으로 스트립(strip)에 아연이나 아연-철 합금에 의한 도금을 실시하는 전기도금공정에서는 고온의 도금용액에 의해 다량의 흄이 발생되고 이러한 흄의처리장치가 운영되고 있다.In general, a large amount of fume is generated by a high temperature plating solution in an electroplating process in which a plating of a strip by zinc or a zinc-iron alloy is performed, and an apparatus for treating such fume is operated.

즉, 제1도에 도시된 바와같이 스트립(S)은 디플랙터 롤(Deflector Roll)(110)을 거쳐 도금조(120)에 잠겨 있는 콘덕터롤(Conductor Roll)(112)로 이송되면서 도금용액(122)에 의한 전기화학반응에 의해 도금되어지고, 상기 도금조(120)의 도금용액(122)은 60℃정도의 고온이며 페하(pH) 1-3정도의 강산성 물질로써 스트립(S) 도금중 다량의 흄(H)을 발생시킨다.That is, as shown in FIG. 1, the strip S is transferred to the conductor roll 112 immersed in the plating bath 120 through the deflector roll 110 and the plating solution. Plated by the electrochemical reaction by (122), the plating solution 122 of the plating bath 120 is a high temperature of about 60 ℃ and strip (S) as a strong acid material of about pH (pH) 1-3 It generates a large amount of fume (H).

이러한 흄(H)은 도금조(120)상부로 위치하는 후드(150)를 이용하여 외부로 방출되고, 상기 후드(150)는 대략의 사각뿔 형상으로 형성되며 상부측은 연도(stack)(미도시)로 향하는 덕트(duck)(13)와 연결된다.The fume (H) is discharged to the outside by using a hood 150 positioned above the plating bath 120, the hood 150 is formed in a substantially square pyramid shape and the upper side is a stack (not shown) It is connected with a duct 13 to the.

그런데, 이러한 종래의 후드(150)에 있어서는 덕트(130)로 향하는 고온의 흄(H)은 덕트(130)의 내표면(131)에 접촉하고, 후드(150)의 내, 외부온도차로 인하여 덕트 내표면(131)에서 응축되며, 이 응축흄(H')은 하부로 떨어져 스트립(S)표면에 드롭마크(drop mark)를 발생시켜 스트립(S)의 표면결함을 유발하는 치명적인 문제점이 있었다.By the way, in the conventional hood 150, the hot fume H directed toward the duct 130 contacts the inner surface 131 of the duct 130, and the duct 130 is caused by the difference in the inner and outer temperatures of the hood 150. Condensation on the inner surface 131, the condensation fume (H ') is falling down to generate a drop mark (drop mark) on the surface of the strip (S) has a fatal problem causing the surface defect of the strip (S).

본 고안은 상기한 바와같은 종래의 문제점을 개선하기 위하여 안출된 것으로, 그 목적은 전기도금시 생성되는 흄이 하부로 떨어지는 것에 의해 스트립에 표면결함이 발생하는 것을 방지하도록 된 이중 흄후드를 제공함에 있다.The present invention was devised to improve the above-mentioned conventional problems, and an object thereof is to provide a double fume hood which is intended to prevent surface defects from occurring due to the falling of fumes generated during electroplating. have.

상기 목적을 달성하기 위한 기술적인 구성으로서, 본 고안은 스트립에 전기도금을 행하는 공정등에서 발생하는 흄을 도금액조의 상부에 설치된 대략의 사각뿔형상의 후드로써 흡입하여 외부로 제거하도록 된 통상의 흄처리장치에 있어서, 상기 후드는 외측몸체와 내측몸체로 둘러쌓인 공간을 형성하고 상기 외측몸체는 수공급배관에 연결되어 공간측으로 향하는 수분사노즐을 상부에 다수개 장착하며, 상기 내측몸체는 관통흡입공을 다수개 형성함은 물론, 상기 내측몸체와 외측몸체의 하측 연결벽에는 밸브를 가지는 배출배관을 다수개 장착함을 특징으로 하는 응축액 낙하 방지용 흄후드를 마련함에 의한다.As a technical configuration for achieving the above object, the present invention is a conventional fume treatment device is to suck the fumes generated in the process of performing electroplating on the strip by suction with a roughly square pyramid-shaped hood installed on the upper portion of the plating bath. In the hood, the hood forms a space surrounded by the outer body and the inner body and the outer body is connected to the water supply pipe and a plurality of water spray nozzles directed toward the space side, the inner body is a through suction hole Forming a plurality of, of course, by providing a condensate fall prevention fume hood, characterized in that a plurality of discharge pipe having a valve is mounted on the lower connection wall of the inner body and the outer body.

이하 본 고안의 일실시예를 첨부된 도면에 의거하여 보다 상세히 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 고안에 따른 응축액 낙하 방지용 흄후드이다.3 is a fume hood for preventing condensate drop according to the present invention.

상기 외측몸체(12)는 상부측에 다수개의 수공급배관(40)이 장착되는데, 상기 수공급배관(40)의 단부에는 노즐몸체(30)가 나사결합되고, 상기 노즐몸체(30)는 전방측, 즉 공간(S)측으로 향하는 수분사노즐(32)을 다수개 형성하며, 또한 회전날개(36)를 가지는데 상기 회전날개(36)는 노즐몸체(30)에 장착되어 수분사노즐(32) 전방측으로 위치하도록 한다.The outer body 12 has a plurality of water supply pipe 40 is mounted on the upper side, the nozzle body 30 is screwed to the end of the water supply pipe 40, the nozzle body 30 is the front It forms a plurality of water spray nozzles 32 toward the side, that is, the space (S) side, and also has a rotary blade 36, the rotary blade 36 is mounted to the nozzle body 30 is a water spray nozzle 32 ) To the front side.

상기 내측몸체(14)는 공간(S)측으로 점차적으로 그 내경이 축소되는 흡입공(16a)이 형성된 흡입관(16)을 다수개 고정한다.The inner body 14 fixes a plurality of suction pipes 16 formed with suction holes 16a whose inner diameters are gradually reduced toward the space S side.

상기 연결벽(13)에는 배출배관(22)을 다수개 고정하고, 상기 배출배관(22)의 각각은 유체흐름을 차단하거나 통과시키도록 하는 밸브(24)를 갖춘다.A plurality of discharge pipes 22 are fixed to the connecting wall 13, and each of the discharge pipes 22 has a valve 24 for blocking or passing the fluid flow.

물론, 상기 수공급배관(40)도 차단밸브(미도시)를 갖추며, 상기 밸브들은 전기도금 설비를 동작시키기 위한 제어부에 전기적으로 연결되어짐이 바람직하다.Of course, the water supply pipe 40 is also provided with a shutoff valve (not shown), the valves are preferably electrically connected to the control unit for operating the electroplating equipment.

상기 구성으로 된 본 고안의 작용 및 효과를 설명한다.The operation and effects of the present invention having the above configuration will be described.

제3도에 도시된 바와같이 전기도금시 발생되는 흄은 도면의 화살표 방향으로 이동하여 후드(10)의 공간(S)을 통하여 후드(10)상측의 덕트(미도시)로 배출된다.As shown in FIG. 3, the fumes generated during electroplating move in the direction of the arrow in the drawing and are discharged to the duct (not shown) above the hood 10 through the space S of the hood 10.

상기 공간(S)에 위치하고 있는 흄은 저온인 외측몸체(12)의 내표면에 부딪혀 응축되고,이러한 응축흄(50)은 외측몸체(12)의 공간(S)측 내표면 또는 내측몸체(14)의 공간(S)측 내표면을 따라 하부로 흘러내리거나 또는 각각의 내표면에 고착되는바 흡입공(16a)을 통해 하부측으로 떨어지지 않는데 이는 흄의 흐름 때문이다.The fume located in the space S is condensed by colliding with the inner surface of the outer body 12 at low temperature, and the condensation fume 50 is the inner surface of the space S side of the outer body 12 or the inner body 14. It does not flow down to the bottom along the inner surface of the space (S) side of) or adhere to each inner surface and fall to the lower side through the suction hole 16a because of the flow of the fume.

이러한 응축흄(50)은 배출배관(22)을 통해 적절하게 배출될 수 있고, 라인 휴지시 수공급배관(40)을 통해 물이 공급되면 수분사노즐(32)로 분사되고 회전날개(36)에 의해 사방으로 퍼지면서 내, 외측몸체(12)(14) 및 흡입공(16a)주위에 고착된 흄을 제거할 수 있는 것이다.The condensation fume 50 may be properly discharged through the discharge pipe 22, and when water is supplied through the water supply pipe 40 when the line is idle, it is injected into the water spray nozzle 32 and the rotary blade 36 By spreading in all directions by the inside, it is possible to remove the fume fixed around the outer body 12, 14 and the suction hole (16a).

상술한 바와같이 본 고안에 따르면, 전기도금작업시 발생되는 흄 방출장치인 후드를 내측몸체(14)와 외측몸체(12)로 둘러싸여 공간(S)을 형성하도록 한 이중구조로 함으로써 응축흄이 하부로 떨어져 스트립에 표면결합에 발생시키는 것을 방지할 수 있고 라인 휴지시 공간(S)내에 수분사토록하여 흄흡입공(16a)의 막힘을 방지하여 안정적인 전기도금작업이 가능토록 한 실용상의 우수한 효과를 가진다.As described above, according to the present invention, the condensation fume is lowered by forming a hood (S) surrounded by the inner body 14 and the outer body 12 to form a space S, which is a fume discharge device generated during electroplating. It is possible to prevent the surface joining to the strip by falling into the furnace, and to prevent the blockage of the fume suction hole (16a) by blocking water in the space (S) when the line is idle.
