Description

3층 피복 이형강관의 분말융착식 코팅장치{A COATING APPARATUS HAVING POWDER FUSION SPLICE TYPE FOR STEEL PIPE WITH SPECIAL CONNECTIONS COATED WITH 3 LAYERS}Powder-coated coating apparatus for three-layer coated deformed steel pipe {A COATING APPARATUS HAVING POWDER FUSION SPLICE TYPE FOR STEEL PIPE WITH SPECIAL CONNECTIONS COATED WITH 3 LAYERS}

본 고안은 3층 피복 이형강관의 분말융착식 코팅장치에 관한 것으로서, 특히 신속하면서도 고품질의 코팅작업이 가능하도록 하는 3층 피복 이형강관의 분말융착식 코팅장치에 관한 것이다.The present invention relates to a powder fusion coating apparatus for a three-layer coated release steel pipe, and more particularly, to a powder fusion coating apparatus for a three-layer coated release steel pipe to enable a quick and high quality coating operation.

도 1에는 통상적인 강관의 코팅공정이 도시되어 있다.1 shows a coating process of a conventional steel pipe.

도시된 바와 같이, 먼저 쇼트 블라스팅에 의해 직관의 내외면에서 녹을 제거한다.As shown, first, rust is removed from the inner and outer surfaces of the straight pipe by shot blasting.

다음, 이형관을 형성하기 위해 입고된 상기 직관을 적당한 길이로 절단한다(도 2a).Next, the straight tube received to form a release tube is cut into appropriate lengths (FIG. 2A).

그리고, 상기 직관의 단부를 확대하는 수구성형을 실시한다(도 2b). 이는 통상적인 파이프 확경장치를 이용한다.Then, a male configuration for enlarging the end portion of the straight pipe is performed (FIG. 2B). This uses a conventional pipe expanding device.

다음, 이형관을 형성하기 위해, 상기 직관을 경사지게 절단한 후 용접을 실시한다. 그리고, 상기 용접부위를 청소한다(도 2c).Next, in order to form a release tube, the straight tube is inclinedly cut and then welded. Then, the welded portion is cleaned (FIG. 2C).

용접 완료된 이형관을 가열로에 넣어 200∼300℃로 균일하게 가열한다(도 2d).The welded release tube is placed in a heating furnace and uniformly heated to 200 to 300 ° C. (FIG. 2D).

다음, 정전기 도장법에 의해 FBE(Fusion Bonded Epoxy)를 에어건을 이용하여 3방향으로 분사하여 강관의 온도에 의해 융착되도록 한다(도 2e). 이를 위해, 크레인으로 상기 강관을 인양한 상태에서 분사하도록 한다.Next, FBE (Fusion Bonded Epoxy) is sprayed in three directions using an air gun to be fused by the temperature of the steel pipe by electrostatic coating (FIG. 2E). To this end, the crane is sprayed in the lifted state with the crane.

그리고, 상기 에폭시 도장면 위에 수작업으로 개질 폴리에틸렌 분말을 살포한다(도 2f). 이를 위해, 크레인으로 상기 강관을 인양한 상태에서 부삽과 같은 적당한 도구를 사용하여 수작업으로 표면에 뿌리게 되는데, 강관의 표면 온도에 의해 자연스럽게 융착하게 된다. 상기 개질 폴리에틸렌층은 후술하는 폴리에틸렌층의 접착제로서 역할한다.Then, the modified polyethylene powder is sprayed by hand on the epoxy coating surface (FIG. 2F). To this end, the steel pipe is lifted by a crane and manually sprayed onto the surface using a suitable tool such as shovel, which is naturally fused by the surface temperature of the steel pipe. The modified polyethylene layer serves as an adhesive of the polyethylene layer described later.

다음, 상기 강관의 표면에 개질 폴리에틸렌 분말의 살포와 유사하게 수작업을 통해 폴리에틸렌 분말을 살포하여 코팅처리를 완료한다(도 2g).Next, similar to the spraying of the modified polyethylene powder on the surface of the steel pipe by spraying the polyethylene powder by hand to complete the coating treatment (Fig. 2g).

다음, 3차에 걸쳐서 코팅처리된 이형관을 물탱크에 침지시켜 냉각함으로써 코팅층을 응고시킨다(도 2h).Next, the coating layer is solidified by immersing and cooling the release tube coated with the water in the water tank three times (FIG. 2H).

그리고, 쇼트 블라스팅에 의해 상기 이형관의 내부를 청소한다(도 2i).Then, the inside of the release tube is cleaned by shot blasting (FIG. 2I).

마지막으로, 상기 이형관의 내부를 에어건 등에 의해 액상 에폭시 수지로 도장한다(도 2j).Finally, the inside of the release tube is coated with a liquid epoxy resin by an air gun or the like (FIG. 2J).

그런데, 종래에는 도 2e 내지 도 2g에 도시된 바와 같이, 에어건을 사용하다가 부삽 등으로 전환하여 코팅제를 강관의 표면에 살포하기 때문에 공정을 변경하기 위한 시간이 많이 소요되어 생산성이 떨어졌다.However, in the related art, as shown in FIGS. 2E to 2G, since the coating is sprayed onto the surface of the steel pipe by using an air gun and then switching to the shovel, the process takes a long time to change the process, thereby reducing productivity.

또한, 부삽을 이용하여 코팅제를 살포하기 때문에 제품이 불균일하다는 단점도 있었다.In addition, there is a disadvantage in that the product is non-uniform because it is spraying the coating using the shovel.

또한, 작업자가 직접 코팅제를 도포하기 때문에 인체에 유해한 물질에 지속적으로 노출될 우려가 높았다.In addition, since the operator directly applies the coating agent, there is a high risk of continued exposure to substances harmful to the human body.

본 고안은 상기한 문제점을 해결하기 위해 안출된 것으로서, 고안의 목적은 고품질의 제품을 신속하게 생산할 수 있는 3층 피복 이형강관의 분말융착식 코팅장치를 제공하는데 있다.The present invention has been made to solve the above problems, the object of the present invention is to provide a powder-fusion coating apparatus of three-layer coated release steel pipe that can quickly produce a high quality product.

또한, 작업자가 인체에 유해한 환경에 노출되지 않도록 하는 3층 피복 이형강관의 분말융착식 코팅장치를 제공하는데 있다.In addition, the present invention provides a powder-fusion coating apparatus for a three-layer coated release steel pipe to prevent an operator from being exposed to an environment harmful to a human body.

전술한 목적을 달성하기 위해, 본 고안에 따른 3층 피복 이형강관의 분말융착식 코팅장치는,In order to achieve the above object, the powder-fusion coating device of the three-layer coated release steel pipe according to the present invention,

상기 배출관(200)은 에어 흐름방향으로 경사지게 배치되어 있다. 이에 따라, 에어가 호퍼(100)로 역류하는 것이 방지될 수 있다.The discharge pipe 200 is disposed to be inclined in the air flow direction. Accordingly, backflow of air into the hopper 100 can be prevented.

상기 에어분사수단(300)으로는 에어펌프나 압축공기탱크 등이 사용될 수 있다.As the air injection means 300, an air pump or a compressed air tank may be used.

상기 밸브장치(500)와 에어분사수단(300)에는 제어장치(600)가 연결되어 있어 공정에 따라 선택적으로 밸브장치(500)가 개폐될 수 있다.The control device 600 is connected to the valve device 500 and the air injection means 300 so that the valve device 500 can be selectively opened and closed according to a process.

상기 에어건(400)은 이형관(10) 둘레로 3개 이상 설치되어 있어, 3방향 이상에서 분사되도록 함으로써 신속한 도포가 이루어지도록 하는 것이 좋다.Three or more air guns 400 are installed around the release tube 10, so that the spraying in three or more directions may be performed quickly.

더욱이, 상기 에어건(400)은 코팅실 내에 배치되고, 상기 호퍼(100)는 실외에 배치되도록 하면, 코팅제의 소모상태를 쉽게 확인할 수 있고, 코팅시 코팅제 분말이 비산하여 어느 하나의 호퍼에 다른 성분의 코팅제가 함입되는 것이 방지될 수 있다.Furthermore, when the air gun 400 is disposed in the coating chamber, and the hopper 100 is disposed outdoors, the consumption state of the coating agent can be easily confirmed, and the coating powder is scattered during coating so that the other constituents in any one hopper. Of the coating agent can be prevented.

또한, 도 4에 도시된 바와 같이, 고정 프레임(900)과, 상기 에어건(400)의 직선이송을 안내하기 위한 직선이송수단(700)과, 강관을 회전시키기 위한 회전구동수단(800)을 함께 구비하여 자동으로 코팅작업이 이루어지도록 할 수 있다.In addition, as shown in Figure 4, together with the fixed frame 900, the linear transfer means 700 for guiding the linear movement of the air gun 400, and the rotary driving means 800 for rotating the steel pipe together Equipped with a coating can be made automatically.
