It is about.

일반적으로, 전기강판 표면에 도포되는 절연코팅은 슬러지 상태의 도포액을 분사하여 코팅하는 것으로, 이러한 절연코팅의 피막밀착성을 향상시켜 모터 등에 사용할 때 와전류 손실을 최소화시키기 위해 건조로를 통해 건조시킨 후 코일형태로 권취하게 된다.In general, the insulation coating applied to the surface of the electrical steel sheet is to spray by coating the coating liquid in the sludge state, and to improve the film adhesion of the insulation coating to dry through a drying furnace to minimize the eddy current loss when used in a motor, etc. It is wound up in the form.

예컨대, 도 1에 도시된 바와 같이, 절연코팅된 전기강판(1)은 건조로(2)를 통과하면서 건조되고, 이에 따라 피막밀착성이 향상되게 되며, 건조로(2)를 통과한 뒤 코일형태로 권취되게 된다.For example, as shown in Figure 1, the insulating coated electrical steel sheet 1 is dried while passing through the drying furnace 2, thereby improving the film adhesion, and after passing through the drying furnace 2 coil form Will be wound up.

그런데, 종래 건조로(2)에는 진행되는 내부상황, 즉 건조상태를 육안으로 확인할 수 있는 수단이 없어 최종 건조후에야 건조로(2) 내부에서의 건조불량을 유추할 수 밖에 없었다.However, the conventional drying furnace 2 has no means of visually confirming the progress of the internal situation, that is, the dry state, and has been forced to infer drying defects in the drying furnace 2 only after the final drying.

따라서, 건조불량에 따른 상당량의 스크랩이 발생되게 되고, 이는 수율 하락은 물론 제조원가를 상승시키는 요인으로 작용하게 된다.Therefore, a considerable amount of scrap is generated due to poor drying, which acts as a factor in lowering yield and increasing manufacturing cost.

본 발명은 상술한 바와 같은 종래 기술상의 한계점을 감안하여 이를 해결하고자 창출한 것으로, 건조로의 일측 벽에 구멍을 뚫고 씰링된 투명유리를 설치하여 건조로 내부를 수시로 관찰할 수 있도록 함으로써 건조불량을 사전에 미리 검출할 수 있고, 그에 따라 스크랩양을 줄일 수 있으며, 제조원가도 낮출 수 있도록 한 건조로 내부 관찰장치를 제공함에 그 주된 목적이 있다.The present invention was created in view of the limitations of the prior art as described above, to solve this problem, by installing a transparent glass sealed through a hole on one side of the drying furnace to observe the interior of the drying oven from time to time in advance The main purpose of the present invention is to provide an internal observing apparatus that can detect in advance, thereby reducing the amount of scrap and lowering the manufacturing cost.

이하에서는, 첨부도면을 참고하여 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

도 2는 본 발명에 따른 건조로 내부 관찰장치의 개념도이고, 도 3은 본 발명에 따른 건조로 내부 관찰장치의 설치상태도이다.2 is a conceptual diagram of a drying furnace internal observing apparatus according to the present invention, Figure 3 is an installation state diagram of the drying furnace internal observing apparatus according to the present invention.

도 2 내지 도 3에 도시된 바와 같이, 본 발명에 따른 건조로 내부 관찰장치는 건조로(2)의 일측 벽면에 설치된다.As shown in Figure 2 to 3, the drying furnace internal observation device according to the invention is installed on one side wall of the drying furnace (2).

즉, 상기 건조로(2)의 일측 벽면에는 구멍이 천공되고, 상기 구멍에는 플랜지(100)가 볼트 체결되어 고정된다.That is, a hole is drilled in one wall surface of the drying furnace 2, and the flange 100 is bolted and fixed to the hole.

이때, 상기 플랜지(100)에는 접속관(110)이 일체로 고정된다.At this time, the connecting pipe 110 is integrally fixed to the flange 100.

또한, 상기 접속관(110)에는 고정판(200)이 고정되는데, 상기 고정판(200)에는 상기 접속관(110)과 동일 직경의 관찰구멍(210)이 천공 형성된다.In addition, the fixing plate 200 is fixed to the connection pipe 110, and the observation plate 210 having the same diameter as the connection pipe 110 is formed in the fixing plate 200.

그리고, 도시되지는 않았지만 상기 고정판(200)의 적소, 바람직하기로는 관찰구멍(210) 최근접측 임의의 위치에는 고정볼트(미도시)가 일체로 돌출형성된다.Although not shown, a fixing bolt (not shown) is integrally formed at an arbitrary position of the fixing plate 200, preferably at a position adjacent to the observation hole 210.

한편, 상기 고정판(200)의 전면에는 상기 고정판(200)과 대응되는 형상의 유동판(300)이 밀착된다.On the other hand, the front of the fixed plate 200 is in close contact with the flow plate 300 of the shape corresponding to the fixed plate 200.

상기 유동판(300)은 회전축(400)에 의해 상기 고정판(200)에 긴밀히 밀착되며, 상기 회전축(400)을 중심으로 고정판(200)에 형성된 관찰구멍(210)의 원중심과, 유동판(300)에 형성된 투명유리(320)의 원중심이 서로 동일 거리에 놓이도록 형성된다.The flow plate 300 is in close contact with the fixed plate 200 by the rotation shaft 400, the center of the observation hole 210 formed in the fixed plate 200 about the rotation shaft 400, and the flow plate ( The centers of the transparent glass 320 formed on the 300 are formed to be at the same distance from each other.

따라서, 상기 유동판(300)이 회전하게 되면 상기 투명유리(320)와 관찰구멍(210)은 정확하게 일치하게 된다.Therefore, when the flow plate 300 is rotated, the transparent glass 320 and the observation hole 210 are exactly matched.

상기 투명유리(320)는 유동판(300)에 천공된 구멍(도면번호 미병기)을 밀폐하는 부재로 건조로(2) 내부롤 육안으로 관찰할 수 있도록 하여 주는 부재이다.The transparent glass 320 is a member that seals a hole (not shown in the drawing) which is drilled in the flow plate 300, and is a member that allows the inside of the drying furnace 2 to be visually observed.

뿐만 아니라, 상기 투명유리(320)는 교체가능함과 동시에 긴밀하고 견고한 고정을 위해 링 형상의 보호플랜지(330)에 의해 볼트 체결된다.In addition, the transparent glass 320 is replaceable and bolted by a ring-shaped protective flange 330 for tight and rigid fixing.

또한, 상기 유동판(300)의 전면 임의의 위치에는 손잡이(310)가 부설되며, 상기 유동판(300)이 회전되는 반경을 따라 안내공(340)이 천공된다.In addition, the handle 310 is placed in any position on the front surface of the flow plate 300, the guide hole 340 is punctured along the radius of the rotation of the flow plate 300.

이때, 상기 안내공(340)에는 상술한 고정판(200)에 구비된 고정볼트(미도시)가 끼워지며, 상기 고정볼트에는 고정너트(350)가 체결된다.At this time, the fixing hole (not shown) provided in the fixing plate 200 is inserted into the guide hole 340, and the fixing nut 350 is fastened to the fixing bolt.

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

평상시에는 투명유리(320)가 하방향으로 쳐진 상태로 유지되며 고정너트(350)의 체결력에 의해 관찰구멍(210)은 밀폐된 상태를 유지하게 된다.In general, the transparent glass 320 is held in a downward direction and the observation hole 210 is maintained in a closed state by the fastening force of the fixing nut 350.

즉, 상기 관찰구멍(210)은 유동판(300)의 투명유리(320)가 없는 부분에 의해 밀폐되는 것이다.That is, the observation hole 210 is sealed by a portion of the flow plate 300 where there is no transparent glass 320.

이와 같이 유지되는 도중에 건조로(2) 내부를 관찰할 필요가 있을 경우, 작업자는 고정너트(350)를 풀고 손잡이(310)를 파지한 다음 유동판(300)을 반시계방향으로 회전시킨다.When it is necessary to observe the inside of the drying furnace 2 during the maintenance, the worker loosens the fixing nut 350, grips the handle 310, and then rotates the flow plate 300 counterclockwise.

이에 따라, 상기 유동판(300)은 회전축(400)을 중심으로 회전이동하게 되는데 이때 안내공(340)이 고정볼트를 기점으로 움직이면서 안내되게 된다.Accordingly, the flow plate 300 is rotated about the rotating shaft 400, the guide hole 340 is guided while moving the fixed bolt to the starting point.

따라서, 상기 유동판(300)은 360°회전되는 것이 아니라 상기 안내공(340) 내에서 회전되게 되며, 이를 통해 상기 유동판(300)은 관찰구멍(210)을 벗어나는 일이 없기 때문에 결국 관찰구멍(210)은 유동판(300) 아니면 투명유리(320) 둘 중 하나에 의해 항상 밀폐된 상태를 유지하게 된다.Therefore, the flow plate 300 is not rotated 360 °, but is rotated in the guide hole 340, through which the flow plate 300 does not escape the observation hole 210 eventually through the observation hole 210 is always maintained in a closed state by either the flow plate 300 or the transparent glass 320.

이렇게 하여, 투명유리(320)가 관찰구멍(210)에 일치되게 되면 작업자는 고정너트(350)를 조여 유동판(300)의 유동을 방지한 후 건조로(2) 내부를 관찰하게 된다.In this way, when the transparent glass 320 is matched with the observation hole 210, the operator tightens the fixing nut 350 to prevent the flow of the flow plate 300, and then observes the interior of the drying furnace (2).

이후, 관찰이 종료되면 신속히 고정너트(350)를 풀어 투명유리(320)를 원위치시켜야 하는데 이는 건조로(2) 내부가 고열로 유지되기 때문에 투명유리(320)의 파손에 따른 열손실을 방지하기 위함이다.Afterwards, when the observation is finished, the fixing nut 350 needs to be released quickly to return the transparent glass 320 to the original position, which prevents heat loss due to breakage of the transparent glass 320 because the inside of the drying furnace 2 is maintained at a high temperature. For sake.

이상에서 상세히 설명한 바와 같이, 본 발명은 건조로 내부 관찰장치를 통해 수시로 건조로 내부를 관찰할 수 있어 건조불량을 사전에 미리 검출할 수 있고, 그에 따라 스크랩양을 줄일 수 있으며, 제조원가도 낮추는 효과를 제공한다.As described in detail above, the present invention can observe the interior of the drying furnace from time to time through the drying furnace internal observing device to detect the drying defect in advance, thereby reducing the amount of scrap, and lowers the manufacturing cost To provide.
