Description

스트립 표면의 유체 유도노즐{Induced fluid nozzle of strip surface}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a fluid-

본 발명은 스트립 표면의 유체 유도노즐에 관한 것으로, 더욱 상세하게는 스트립 표면에서 제거되는 유체가 비산되지 않고 스트립 표면을 따라서 외부로 배출할 수 있도록 유도하는 스트립 표면의 유체 유도노즐에 관한 것이다.
The present invention relates to a fluid induction nozzle on a surface of a strip, and more particularly, to a fluid induction nozzle on a strip surface that induces a fluid removed from the surface of a strip to be discharged outside along the surface of the strip without scattering.

일반적으로 스트립(강판)의 표면에는 제조공정 및 작업환경에 따라서 압연유 등과 같은 이물질을 포함한 유체가 남아있으므로 생산품질을 위해서 스트립의 표면에 분사노즐(10)을 통해서 압축공기를 분사하여 이물질을 제거한다.Generally, on the surface of a strip (steel plate), fluid containing foreign substances such as rolling oil remains in accordance with the manufacturing process and working environment. Therefore, for production quality, foreign matter is removed by spraying compressed air through the spray nozzle 10 on the surface of the strip .

그러나 종래에는 고압의 압축공기로 인해서 이물질이 주변으로 비산되므로 스트립 및 주변설비의 2차 오염을 유발하는 심각한 문제점을 갖게 되었다.However, conventionally, since the foreign matter is scattered to the surroundings due to the high-pressure compressed air, there has been a serious problem causing secondary contamination of the strip and peripheral equipment.

특히 종래에는 이물질이 스트립의 상부면에 남아있게 되므로 생산품질을 저하하는 문제점을 갖게 되었다.
Particularly, conventionally, since the foreign matter remains on the upper surface of the strip, the quality of the product is lowered.

FIG.

본 발명은 외부에서 공급하는 압축공기를 내부로 유입하며 하부에 배출공(111)을 형성하는 본체(110)와; 상기 본체(110)의 하부에 결합하며 상부 일측에 상기 배출공(111)과 연결하도록 유입공(122)을 구비하고 전방에 하부방향으로 갈수록 내측으로 경사지도록 제1경사부(121)를 형성하는 상부몸체(120)와; 상기 상부몸체(120)의 하부에 결합하되 전방에 상기 제1경사부(121)와 일정간격 떨어지도록 제2경사부(131)를 형성하는 하부몸체(130)로 이루어진다.The present invention includes a main body 110 for introducing compressed air supplied from the outside into the inside thereof and forming a discharge hole 111 at a lower portion thereof; The first inclined portion 121 is coupled to the lower portion of the main body 110 and has an inlet hole 122 to be connected to the discharge hole 111 at one side of the upper portion thereof and inclined inward toward the lower side in the forward direction An upper body 120; And a lower body 130 coupled to a lower portion of the upper body 120 and forming a second inclined portion 131 at a predetermined distance away from the first inclined portion 121 in front of the upper body 120.

특히 상기 본체(110)는 주변설비에 고정하여 외부에서 공급하는 압축공기를 전달받아서 상기 상부몸체(120)의 내부로 공급하는 역할을 수행한다.Particularly, the main body 110 is fixed to peripheral equipment and receives compressed air supplied from the outside and supplies the compressed air to the inside of the upper body 120.

이때 상기 본체(110)의 내부에 다수의 통공(113)을 구비하는 분산판(112)을 형성하여 상기 본체(110)의 내부로 들어오는 압축공기가 한 곳으로 집중하지 않고 상기 통공(113)을 통과하면서 분산하여 상기 배출공(111)으로 균일한 압력으로 공급할 수 있도록 유도한다.At this time, a dispersion plate 112 having a plurality of through holes 113 is formed in the main body 110 so that the compressed air entering the main body 110 does not concentrate in one place, So that they can be supplied to the discharge hole 111 at a uniform pressure.

한편, 상기 제1경사부(121)는 전방에서 하부방향으로 갈수록 점차 내측으로 경사지도록 형성하여 압축공기가 스트립(A)의 이동방향으로 분사되도록 유도한다.The first inclined portion 121 is inclined inward gradually from the front to the bottom so as to induce the compressed air to be sprayed in the moving direction of the strip A.

여기서 상기 제1경사부(121)와 제2경사부(131)는 서로 일정간격 떨어진 상태로 압축공기가 원활하게 배출할 수 있다.Here, the first inclined portion 121 and the second inclined portion 131 can smoothly discharge compressed air while being spaced apart from each other by a predetermined distance.

특히 상기 제1경사부(121)와 제2경사부(131)는 서로 동일한 방향으로 나란히 형성하여 압축공기가 배출할 수 있도록 형성할 수 있다.In particular, the first inclined portion 121 and the second inclined portion 131 may be formed in parallel with each other in the same direction so that compressed air can be discharged.

여기서 상기 제2경사부(131)의 전방 상부 모서리에 완만한 곡선형태로 굴곡진 제1유도부(132)를 형성하고, 상기 제2경사부(131)의 전방 하부 모서리에 완만한 곡선형태로 굴곡진 제2유도부(133)를 형성할 수 있다.A first guiding portion 132 curved in a gentle curved shape is formed at a front upper corner of the second inclined portion 131 and a curved shape is formed at a front lower corner of the second inclined portion 131 in a gentle curved shape The second guide portion 133 can be formed.

따라서 상기 제1유도부(132)와 제2유도부(133)를 통과하는 압축공기가 간섭없이 자연스럽게 배출할 수 있다.Therefore, the compressed air passing through the first induction part 132 and the second induction part 133 can be discharged naturally without interference.

특히, 도 3에 도시한 바와 같이 상기 제1유도부(132)는 상기 제1경사부(121)와 제2경사부(131)의 사이로 압축공기를 자연스럽게 유도하고, 상기 제2유도부(133)는 상기 제1경사부(121)와 제2경사부(131)의 사이를 통과하는 압축공기가 간섭없이 자연스럽게 상기 하부몸체(130)와 스트립(A)의 표면 사이로 통과하면서 빠른 공기의 흐름이 발생하는 코안다 효과(Coanda effect)를 유도할 수 있다.3, the first guiding portion 132 naturally induces compressed air between the first guiding portion 121 and the second guiding portion 131, and the second guiding portion 133 The compressed air passing between the first inclined portion 121 and the second inclined portion 131 flows naturally without any interference between the lower body 130 and the surface of the strip A, A Coanda effect can be induced.

아울러 상기 하부몸체(130)의 하부에 길이방향으로 일정간격 떨어지도록 배열하여 상기 제1경사부(121)와 제2경사부(131)의 사이로 배출하는 압축공기의 이동방향으로 유도하기 위한 다수의 유도판(140)을 포함할 수 있다.And a plurality of first and second inclined portions 121 and 131 arranged in the lower portion of the lower body 130 so as to be separated from each other by a predetermined distance in the longitudinal direction, And may include an induction plate 140.

이때 상기 유도판(140)은 도 4에 도시한 바와 같이 상기 하부몸체(130)를 하부에서 보았을 때 중간을 기준으로 양측으로 갈수록 점차 외측으로 기울어지도록 형성하여 유체가 상기 유도판(140)을 통해서 스트립(A)의 외측으로 배출할 수 있다.4, when the lower body 130 is viewed from the lower side, the guide plate 140 is gradually inclined outward toward both sides with respect to the middle, so that the fluid is guided through the guide plate 140 And can be discharged to the outside of the strip A.

이처럼 상기와 같이 본 발명의 실시예에 대하여 상세히 설명하였으나, 본 발명의 권리범위는 이에 한정되지 않으며, 본 발명의 실시예와 실질적으로 균등의 범위에 있는 구성까지 본 발명의 권리범위에 포함됨은 당연하다.
