Description

아연도금욕조의 이물질 제거 장치{Device removing foreign substances for Bath Of Galvanizing System}Device removing foreign substances for Bath Of Galvanizing System}

본 발명은 아연도금욕조의 이물질 제거 장치에 관한 것으로서, 보다 구체적으로는 전방의 양측에 제1 고리부(13, 23)가 제공되는 상부; 상기 상부의 하측으로 연장 제공되는 지지부(2, 3, 4); 상기 지지부(2, 3, 4)의 중간에 제공되고, 양측에 제2 고리부(33)가 제공되는 연장부(7); 및 상기 지지부(2, 3, 4)에 제공되는 스크래퍼(50)를 포함하는, 아연도금욕조의 이물질 제거 장치에 관한 것이다. The present invention relates to an apparatus for removing foreign substances in a galvanizing bath, and more particularly, to an upper portion provided with first hook portions (13, 23) on both sides of the front; Supports (2, 3, 4) provided extending downwardly of the upper portion; an extension portion 7 provided in the middle of the support portions 2, 3, 4, and provided with a second ring portion 33 on both sides; And it relates to a foreign material removal device of the galvanizing bath, including a scraper (50) provided on the support (2, 3, 4).

일반적으로 용융아연도금라인은 강판의 기계적물성 향상을 위한 열처리공정, 표면특성 향상을 위한 아연도금공정 및 기타 하성처리등을 위한 후처리공정으로 구분된다. 그 중 아연도금공정은 도금품질에 가장 큰 영향을 미치게 되며, 아연도금공정은 용융도금법과 전기도금법이 널리 사용하고 있다. 이 중에 용융도금법은 열처리된 강판을 아연도금욕조에 침지시켜 도금층을 형성시키는 것으로, 전기도금에 비해 많은 도금부착량을 얻을 수 있다. In general, the hot-dip galvanizing line is divided into a heat treatment process for improving the mechanical properties of a steel sheet, a galvanizing process for improving surface properties, and a post-treatment process for other tempering treatments. Among them, the zinc plating process has the greatest influence on the plating quality, and the hot dip plating method and the electroplating method are widely used for the zinc plating process. Among them, the hot-dip plating method forms a plating layer by immersing a heat-treated steel sheet in a galvanizing bath, and can obtain a larger amount of plating than electroplating.

도 1에 도시된 바와 같이, 아연도금욕조(210)에는 아연도금액이 채워져 있고, 공간의 상부에는 이송부(200)가 수평 및 수직의 이동을 제어한다. 이송부(200)에는 본 발명의 지그(300)가 체결되어 함께 이동되고, 지그(300)에는 복수 개의 시편(310)이 연결되어 있다. As shown in FIG. 1 , the galvanizing bath 210 is filled with a galvanizing solution, and the transfer unit 200 controls horizontal and vertical movement in the upper part of the space. A jig 300 of the present invention is fastened to the transfer unit 200 and moved together, and a plurality of specimens 310 are connected to the jig 300 .

지그(300)에 이동에 의해 시편은 아연도금욕조(210)에 담겨지게 되고, 아연도금공정이 진행된다. By moving the jig 300, the specimen is immersed in the galvanizing bath 210, and the galvanizing process is performed.

다만, 이러한 공정을 계속하는 경우에는 금속 이물질들이 욕조 바닥에 계속 쌓이게 되고, 이를 제거하지 않는 경우에는 금속 침전물로 인해 욕조가 파손되는 문제가 발생한다. However, when this process is continued, metal foreign substances are continuously accumulated on the bottom of the bathtub, and if this is not removed, a problem occurs in that the bathtub is damaged due to metal deposits.

따라서 이러한 금속 이물질을 지속적으로 제거해줘야 한다. Therefore, it is necessary to continuously remove these metal foreign substances.

이하 첨부된 도면을 참조하여 본 발명에 대해 구체적으로 설명하기로 한다. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 발명에서는 상기의 과제를 해결하기 위해 다음과 같은 해결 수단을 제공한다. The present invention provides the following solutions to solve the above problems.

전방의 양측에 제1 고리부(13, 23)가 제공되는 상부가 제공된다. 상부에는 전방에는 고리부가 제공되고, 이에 체인이 연결되어 공중의 레일에 연결된다. An upper portion provided with a first ring portion 13, 23 is provided on both sides of the front. The upper part is provided with a hook in the front, and a chain is connected thereto and is connected to the rail in the air.

상기 상부의 하측으로 연장 제공되는 지지부(2, 3, 4, 5)가 연결된다. 지지부는 기둥 형태이고 지지부의 끝단에 스크래퍼(50)와 연결된다. The support parts 2, 3, 4, 5 provided extending downward from the upper part are connected. The support part is in the form of a column and is connected to the scraper 50 at the end of the support part.

상기 지지부(2, 3, 4, 5)의 중간는 별도의 가로부재가 제공되고, 상부의 전방에 대하여 후방으로 연장되어 형성되는 연장부재(6)이 제공되고, 연장부재(6)의 끝단에는 연장부(7)가 제공된다. 연장부(7)의 양측에는 제2 고리부(33)가 제공된다. (도면에는 한쪽에만 도시되어 있고, 다른 끝쪽에 제공되는 고리부 미도시)A separate transverse member is provided in the middle of the support parts 2, 3, 4, 5, and an extension member 6 is provided extending rearwardly with respect to the front of the upper part, and an extension member 6 is provided at the end of the extension member 6 A part 7 is provided. A second ring portion 33 is provided on both sides of the extension portion 7 . (It is shown only on one side in the drawing, and the ring part provided on the other end is not shown)

상기 지지부(2, 3, 4)에 제공되는 스크래퍼(50)를 포함한다. 스크래퍼는 경사지게 제공되어 아연도금욕조의 바닥면을 긁는 것으로 동작한다. 긁은 이후에 긁힌 이물질들을 가둬둔 상태에서 욕조 외부로 제거해야 하므로, 양측면에는 측부(51, 52)가 제공되고, 후방에는 후방부(53)가 제공된다. 스크래퍼(50)와 측부(51, 52), 및 후방부(53)는 함께 공간을 형성하고, 이에 이물질이 쌓이게 된다 and a scraper (50) provided on the support (2, 3, 4). The scraper is provided at an angle and operates by scraping the bottom surface of the galvanized bath. After scraping, since it is necessary to remove the scratched foreign substances to the outside of the bathtub in a confined state, side portions 51 and 52 are provided on both sides, and a rear portion 53 is provided on the rear side. The scraper 50, the side parts 51 and 52, and the rear part 53 together form a space, and foreign substances are accumulated therein.

중요한 것은 욕조의 용액은 스크래퍼(50) 외부로 다시 흘러나가야 하기 때문에 스크래퍼(50)와 측부(51, 52), 및 후방부(53)에는 복수의 홀(100)을 형성하여 용액이 통과하게 한다. It is important to form a plurality of holes 100 in the scraper 50, the sides 51, 52, and the rear part 53, so that the solution in the bath flows back out of the scraper 50 to allow the solution to pass through. .

건물의 천장에 제공되고, 상기 상부의 폭만큼 이격되어 제공되는 한쌍의 레일부(200)가 제공된다. A pair of rail units 200 are provided on the ceiling of a building and are provided spaced apart by the width of the upper portion.

상기 레일부(200)를 따라 이동가능하고, 상기 제1 고리부(13, 23)와 상기 제2 고리부(33)에 체인으로 연결되어, 상기 이물질 제거 장치를 이동시키는 것을 특징으로 한다. It is movable along the rail portion 200, and is connected to the first ring portion 13, 23 and the second ring portion 33 by a chain, characterized in that it moves the foreign material removal device.

도 3은 본 발명의 아연도금욕조의 이물질 제거 장치가 체인부를 통해 공중에 연결되어 있는 모습을 도시하고 있다. 3 shows a state in which the foreign material removal device of the galvanizing bath of the present invention is connected to the air through a chain part.

본 발명의 핵심은 사용되는 체인(12, 22, 32, 43)의 길이를 자유롭게 조절하는 것에 있다. 예를 들어 전방의 체인(12, 22)의 길이는 동일하고, 후방의 체인(32, 42)의 길이는 동일하다. 다만, 전방의 체인(12, 22)과 후방의 체인(32, 42)의 길이는 서로 차이가 있다. 후방의 체인(32, 42)의 길이를 줄이면 스크래퍼(50)가 바닥면에 대해 기울어진 경사는 증가하고, 후방의 체인(32, 42)의 길이를 줄이면 스크래퍼가 바닥면에 대해 기울어진 경사는 감소하게 된다. The essence of the present invention lies in freely adjusting the length of the chains 12, 22, 32, 43 to be used. For example, the front chains 12 and 22 have the same length, and the rear chains 32 and 42 have the same length. However, the lengths of the front chains 12 and 22 and the rear chains 32 and 42 are different from each other. If the length of the rear chains 32 and 42 is reduced, the inclination of the scraper 50 with respect to the floor surface increases, and if the length of the rear chains 32 and 42 is reduced, the inclination of the scraper 50 with respect to the floor surface will decrease

도면에는 미도시되어 있으나, 상기 체인들의 길이를 자동으로 줄이는 액츄에이터를 더 제공한다. 사용자는 상기 액츄에이터를 조절하여 스크래퍼(50)가 바닥면에 대해 기울어지는 경사를 손쉽게 제어할 수 있다. Although not shown in the drawings, an actuator for automatically reducing the length of the chains is further provided. The user can easily control the inclination of the scraper 50 with respect to the floor by adjusting the actuator.

스크래퍼(50)가 바닥면에 기울어진 상태에서 상기 레일을 따라 체인을 전방으로 이동시키는 경우, 스크래퍼(50)가 전방으로 이동하면서 바닥면의 이물질을 긁어내게 된다. 긁은 이후에는 전방의 체인(12, 22)의 길이를 줄이게 되면 스크래퍼(50)의 전방이 위로 향하게 되어 이물질을 담은 상태로 올라오게 된다. 이를 외부로 빼서 이물질을 제거하게 된다. When the chain is moved forward along the rail in a state where the scraper 50 is inclined to the floor, the scraper 50 moves forward to scrape off foreign substances on the floor. After scraping, if the length of the chains 12 and 22 in the front is reduced, the front of the scraper 50 is turned upward, and it comes up in a state containing foreign substances. It is pulled out to remove foreign substances.
