제1도에 도시된 바와같이, 강판(S)은 롤(10)(11)을 거쳐 본 장치(50)에 들어가는데, 상기 롤(10)(11)에는 유체(물과 오일의 혼합물질)가 분사되어 냉각 및 윤활을 돕고, 그 유체는 강판(S)에 묻혀져 이동된다. 상기 강판(S)은 본 장치(50)의 롤(60)에 그 표면이 접촉된는 바, 흡입펌프(81)가 작동되어 롤 내부의 내부방(65)(66)(67)에 진공이 형성되면서 구멍(62)과 탄력체(63)를 통해 강판(S) 표면의 액체성분과 미세한 슬러지 등이 내부방(65)(66)(67)에 흡입되어 배관(68)(69)을 통해 탱크(82)로 이동되고 자력크리너(84)를 통해 철성분의 슬러지는 탱크(86)에 포집되며 순수유체만이 배관(90)으로 이동된다. 그리고, 유체성분이 대부분 제거된 잔류성분들은 탄력체(63) 외표면에 유지되어 있다가 브러시(72)와 챔버(70) 내부에 형성된 진공에 의해 배관(74)으로 이동되고, 탱크(83)를 거쳐 자력크리너(85)에서 슬러지가 제거되며, 소량의 유체가 남아져 재활용토록 된다. 한편, 상기에서 불순물이 걸러진 유체는 배관(90)을 통해 탱크(94)로부터의 물과 적절히 혼합되어 분사노즐(95)(96)을 통해 재활용된다. 또한, 다수개의 구역으로 나뉘어진 롤(60)의 중공부, 즉 내부방(65)(66)(67)의 진공은 강판(S)의 폭에 대응되어 중앙측 내부방(66)만을 진공화할 수 있으며, 마찬가지로 분사노즐(95)(96)의 각 영역(95a)(95b)(95c)(96a)(96b)(96c)도 강판(S)의 폭에 대응되어 중앙측 영역(95b)(96b)에만 유체를 분사시킬 수 있다. 상술한 바와 같이 본 발명에 따르면, 종래에 에어를 분사하여 강판 표면의 이물질을 제거하였던 것과는 달리 진공을 형성하도록 된 본 장치에서 강판표면의 이물질을 흡착하여 처리하고 윤활 및 냉각제는 제활용토록 함으러서, 강판표면을 청정화하여 후처리 작업이 용이하도록 하고, 소음을 제거하여 조용한 작업공간을 이룸은 물론, 재활용에 따른 원가절감 및 환경오염 방지가 있는 효과를 가진다.As shown in FIG. 1, the steel sheet S enters the apparatus 50 via the rolls 10 and 11, wherein the rolls 10 and 11 have a fluid (a mixture of water and oil). Sprayed to help cooling and lubrication, the fluid is buried in the steel plate (S) and moved. The surface of the steel sheet (S) is in contact with the roll 60 of the apparatus 50, the suction pump 81 is operated to form a vacuum in the inner chamber 65, 66, 67 inside the roll While the liquid component and fine sludge on the surface of the steel sheet (S) through the hole 62 and the elastic body 63 is sucked into the inner chamber 65, 66, 67, the tank through the pipe 68, 69 The iron sludge is collected in the tank 86 through the magnetic cleaner 84 and only the pure fluid is moved to the pipe 90. In addition, the residual components from which the fluid components are mostly removed are maintained on the outer surface of the elastic body 63 and then moved to the pipe 74 by the vacuum formed in the brush 72 and the chamber 70, and the tank 83. Through the sludge is removed from the magnetic cleaner (85), a small amount of fluid is left to be recycled. On the other hand, the impurity filtered fluid is properly mixed with the water from the tank 94 through the pipe 90 is recycled through the injection nozzles (95, 96). In addition, the hollow of the roll 60 divided into a plurality of zones, that is, the vacuum of the inner chambers 65, 66, 67 corresponds to the width of the steel sheet S, so that only the central inner chamber 66 can be evacuated. Similarly, the areas 95a, 95b, 95c, 96a, 96b, and 96c of the spray nozzles 95 and 96 may also correspond to the width of the steel sheet S so as to correspond to the width of the steel sheet S. The fluid can be injected only in 96b). As described above, according to the present invention, unlike the conventional injecting air to remove foreign substances on the surface of the steel sheet, in this apparatus to form a vacuum, the foreign material on the surface of the steel sheet is adsorbed and treated, and the lubricating and cooling agents are recycled. In addition, the surface of the steel sheet can be cleaned to facilitate the post-treatment work, and the noise can be removed to create a quiet work space, as well as cost reduction and environmental pollution prevention.
