Description

스트립 세척용 노즐의 회전장치Rotating device for nozzle for strip cleaning

본 고안은 스트립 세척용 노즐의 회전장치, 더욱 상세하게는 냉간압연 공정시 스트립(strip)의 표면에 부착된 압연유를 제거하기 위해 용액을 분사시킬 때 용액의 분산범위를 확대함과 아울러 노즐의 막힘을 방지하여 세척효율을 향상시킬 수 있게 한 스트립 세척용 노즐의 회전장치에 관한 것이다.The present invention extends the dispersion range of the solution when spraying the solution to remove the rolling oil attached to the surface of the strip during the cold rolling process, and more particularly in the cold rolling process. It relates to a rotating device of the nozzle for cleaning strips to prevent cleaning to improve the cleaning efficiency.

일반적으로, 냉간압연시 윤활을 목적으로 도포된 압연유는 스트립의 표면에 부착되고, 이를 후공정에서 제거할 경우에도 스트립의 표면에는 1개당 약 100㎎의 압연유가 잔류되므로, 전처리공정에서 염산 등의 용액을 이용하여 세척작업을 하였다.In general, the rolled oil applied for lubrication during cold rolling is attached to the surface of the strip, and even if it is removed in a post process, about 100 mg of rolled oil remains on the surface of the strip. Washing was performed using the solution.

이 때, 노즐을 통해 용액(세척액)을 분사할 때 상기 노즐이 고정상태로 되어 어느 일부분만을 향해 집중적으로 분사하게 됨으로써 스트립의 전부분에 잔류된 기름성분의 제거가 불가능함에 따라, 잔류된 기름에 의해 소둔로 및 도금로의 온도관리에 영향을 미치게 됨과 아울러 전기도금시 도금 밀착성을 저해시켜 제품의 품질을 떨어뜨리는 문제점이 있었다.At this time, when spraying the solution (washing liquid) through the nozzle, the nozzle is fixed and intensively sprays toward only a portion, thereby making it impossible to remove the oil component remaining in the entire portion of the strip. As a result, the temperature control of the annealing furnace and the plating furnace is affected, and there is a problem of decreasing the quality of the product by inhibiting the adhesion of the plating during electroplating.

또한, 노즐이 고정된 상태에서 용액을 분사할 경우 용액중에 함유된 이물질에 의해 그 노즐공이 막히게 되는 현상이 빈번하였으므로 이에 따라 노즐을 분해하여 수리해야 되는 번거로움과 함께 수리로 인한 휴지시간 만큼 설비가 정지되어 생산성이 떨어지는 등의 문제점도 있었다.In addition, when spraying the solution while the nozzle is fixed, the nozzle hole is frequently clogged by foreign substances contained in the solution. Therefore, the equipment is installed as much as the downtime due to the repair and the trouble of disassembling and repairing the nozzle. There was also a problem that the productivity was lowered due to a stop.

본 고안은 위와 같은 종래의 노즐의 문제점을 감안하여 안출한 것으로서, 그 목적은 용액의 분산범위를 확대하고 노즐공의 막힘현상을 감소시킬 수 있는 스트립 세척용 노즐의 회전장치를 제공하는 것이다.The present invention has been made in view of the above problems of the conventional nozzle, the object is to provide a rotating device of the nozzle for cleaning the strip that can expand the dispersion range of the solution and reduce the clogging of the nozzle hole.

이러한 목적을 달성하기 위한 본 고안은, 용액을 공급하는 배관의 볼트관에 용액의 누수를 방지하는 방수부재를 설치하고 이 방수부재에 노즐공을 구비한 노즐몸체를 회전가능하게 결합하여 노즐몸체를 회전시키면서 용액을 분사함에 따라, 스트립의 전면을 골고루 세척함과 아울러 노즐공의 막힘을 최소화하게 됨을 특징으로 한다.The present invention for achieving the above object is to install a waterproof member to prevent the leakage of the solution in the bolt pipe of the pipe for supplying the solution and rotatably coupled the nozzle body provided with a nozzle hole to the waterproof member As the solution is sprayed while rotating, the front surface of the strip is evenly cleaned and the blockage of the nozzle hole is minimized.

이하, 본 고안의 스트립 세척용 노즐의 회전장치를 첨부도면을 참조하여 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the rotary device of the nozzle for cleaning strips of the present invention will be described.

도 1은 종래의 노즐의 분리사시도이고, 도 2는 그 노즐에 의한 세척수 분사상태를 나타낸 것으로, 용액 공급배관에 형성된 볼트관(1)에 상하로 방수링(4)을 갖춘 유도관(3)을 매개로 노즐(2)을 결합함에 따라 노즐(2)이 고정된 상태에서 용액을 분사하여 세척범위가 제한적이고 노즐막힘 현상이 발생되는 등의 문제점을 위해서 설명한바 있다.Figure 1 is an exploded perspective view of a conventional nozzle, Figure 2 shows the washing water sprayed by the nozzle, the induction pipe (3) having a waterproof ring (4) up and down on the bolt pipe (1) formed in the solution supply pipe By coupling the nozzle 2 through the medium has been described for problems such as spraying the solution in a fixed state of the nozzle 2, the washing range is limited and nozzle clogging occurs.

도 3 및 도 4는 본 고안의 실시예의 노즐 회전장치를 나타낸 분리사시도와 그 결합상태 단면도이고, 도 5는 상기 실시예의 세척수 분사상태를 나타낸 것으로, 세척용액이 공급되는 배관의 말단부에 볼트관(1)이 형성되어 이에 방수관(10)이 나사결합되어 있다.3 and 4 is an exploded perspective view showing the nozzle rotating apparatus of the embodiment of the present invention and a cross-sectional view of the combined state, and FIG. 5 shows the washing water spraying state of the embodiment, and the bolt pipe ( 1) is formed so that the waterproof tube 10 is screwed.

상기 방수관(10)의 관로상에는 격막(11)이 형성되고, 이 격막(11)의 중앙부에는 체결공(12)을 형성하되 그 외측의 소정위치에 적어도 하나 이상의 유출공(13)이 형성되어 있다.A diaphragm 11 is formed on the pipeline of the waterproof tube 10, and a fastening hole 12 is formed in a central portion of the diaphragm 11, and at least one outlet hole 13 is formed at a predetermined position outside the diaphragm 11. have.

상기 방수관(10)의 단부에는 상단이 축소되는 노즐몸체(20)의 회전축(21)이 회전가능하게 삽입되어 고정볼트(30)로 체결되고, 상기 회전축(21)에 비해 확대된 헤드부(22)의 상단에는 유출공(13)을 통해 공급되는 용액에 의해 회전력을 발생시키는 요철부(23)가 조밀하게 형성되며, 이 요철부(23)이 소정위치에는 물을 분사하는 노즐공(24)이 형성되어 있다.At the end of the waterproof tube 10, the rotating shaft 21 of the nozzle body 20 whose upper end is reduced is rotatably inserted and fastened to the fixing bolt 30, and the head portion enlarged compared to the rotating shaft 21 ( 22 is densely formed at the upper end of the concave-convex portion 23 to generate a rotational force by the solution supplied through the outlet hole 13, the concave-convex portion 23 is a nozzle hole 24 for spraying water at a predetermined position ) Is formed.

따라서 상기와 같은 본 고안은, 세척용액이 공급되는 볼트관(1)에 방수관(10)을 매개로 노즐몸체(20)를 설치함에 따라 용액의 누설을 방지하게 되고, 상기 방수관(10)의 격막(11)에 형성된 유출공(13)을 통해 헤드부(22)의 요철부(23)에 용액을 분사시킴에 따라 그 회전축(21)을 기점으로 노즐몸체(20)가 회전된다.Therefore, the present invention as described above, to prevent the leakage of the solution by installing the nozzle body 20 via the waterproof pipe 10 in the bolt pipe (1) to which the washing solution is supplied, the waterproof pipe (10) As the solution is injected into the uneven portion 23 of the head portion 22 through the outflow hole 13 formed in the diaphragm 11 of the nozzle body 20 is rotated from the rotation axis 21 as a starting point.

이와 동시에 요철부(23)의 소정위치에 형성된 노즐공(24)을 용액이 통과됨에따라, 도 4에서와 같이 노즐몸체(20)의 회전과 함께 용액이 분사되어 스트립의 전부분에 골고루 용액을 분사시켜 세척효율을 높이게 된다.At the same time, as the solution passes through the nozzle hole 24 formed at the predetermined position of the uneven portion 23, the solution is sprayed with the rotation of the nozzle body 20, as shown in FIG. Spraying will increase the cleaning efficiency.

또한, 노즐몸체(20)의 회전에 의해 노즐공(24)에 이물질의 잔류가 방지되어 막힘으로 인한 세척휴지시간을 줄이고 보수시간 또한 절약할 수 있다. 한편, 헤드부(22)에 형성된 요철부(23)의 형성방향에 따라 그 노즐몸체(20)의 회전방향이 다르게 되므로 스트립에 용액을 분사하게 여러개의 노즐몸체(20)를 설치할 때 상호 회전방향을 다르게 하여 세척력을 향상시키게 된다.In addition, the remaining of the foreign matter in the nozzle hole 24 is prevented by the rotation of the nozzle body 20 to reduce the washing down time due to clogging, and also the maintenance time can be saved. On the other hand, since the rotation direction of the nozzle body 20 is different depending on the formation direction of the concave-convex portion 23 formed in the head 22, the mutual rotation direction when installing a plurality of nozzle body 20 to spray the solution on the strip Differently improves the cleaning power.

이와 같은 본 고안의 스트립 세척용 노즐의 회전장치는 용액의 분사각을 확장하여 세척효율을 향상시킬 수 있으며, 노즐몸체의 회전에 의해 이물질의 막힘을 최소화하여 수리시간을 절약함에 따라 작업능률을 높일 수 있는 효과가 있다.The rotating device of the strip cleaning nozzle of the present invention can improve the cleaning efficiency by extending the spray angle of the solution, and improve the working efficiency by minimizing the clogging of foreign substances by the rotation of the nozzle body, saving the repair time. It can be effective.
