Description
본 발명은 코팅강관 보온장치에 관한 것으로, 특히 코팅강관의 코팅작업시 재가열하지 않고 1차 가열된 코팅강관의 잠열을 활용하여 수지의 표면광택과 강관과 수지와의 견고한 융착을 가능하도록 하기 위한 코팅강관 보온장치에 관한 것이다.The present invention relates to a coated steel pipe insulation device, in particular a coating to enable the surface gloss of the resin and the solid fusion of the steel pipe and the resin by utilizing the latent heat of the primary heated coated steel pipe without reheating during the coating operation of the coated steel pipe It relates to a steel pipe thermostat.
종래 지하에 매설되는 대형수도관이나 가스관, 송유관으로 사용되는 코팅강관은 부식 등을 방지하기 위하여 폴리에틸렌 수지로 강관의 내면과 표면을 코팅(피복)하여 사용하고 있으며, 상기 수지의 코팅을 위한 여러 가지 종류의 장치들이 개발되어 사용되고 있다.Conventionally, the coated steel pipes used as large water pipes, gas pipes, and oil pipes buried underground are coated (coated) with the inner surface and the surface of the steel pipes with polyethylene resin to prevent corrosion, and various kinds for coating the resins. Devices have been developed and used.
그러나 종래의 강관코팅방법은 강관을 버너(burner)로 가열하여 고온의 상태를 만들고, 상기 고온의 강관에 수지분말을 뿌려 융착시키는 1차코팅작업 후에 다시 강관과 수지와의 융착을 견고히 하고, 수지의 표면에 광택을 주기 위해서 다시 버너로 코팅강관을 재가열하게 된다.However, the conventional steel pipe coating method is to heat the steel pipe with a burner (burner) to create a high temperature state, after the primary coating operation to sprinkle the resin powder on the high temperature steel pipe and fusion again to solidify the fusion between the steel pipe and the resin, The coated steel pipe is then reheated with a burner to luster the surface of the glass.
그러나 상기와 같은 방법은 강관의 재가열은 필수적공정이므로 버너의 사용으로 인한 연료소비와 또 이로 인해 강관생산비용이 상승하는 폐단을 갖게되는 것이다. 또 코팅강관의 재가열과정에서 오히려 강관에 코팅된 수지가 손상될 우려가 매우 높아 상품성이 낮아지는 폐단을 갖기도 하는 것이다.However, since the reheating of the steel pipe is an essential process as described above, the fuel consumption due to the use of the burner and the resulting cost of the steel pipe production are increased. In addition, during the reheating process of the coated steel pipe, the resin coated on the steel pipe is very likely to be damaged, and thus it may have a closed end that lowers the commerciality.
본 발명은 종래의 방법과 달리 버너를 사용하여 코팅강관을 재가열하는 것이 아니고, 수지분말을 강관에 융착시키기 위해서 강관을 먼저 가열하는 1차가열공정에 의해 가열된 강관은 상당시간동안 고온을 유지한다는 점에 착안하여 1차가열된 코팅강관의 잠열을 그대로 활용할 수 있도록 상기 1차 가열되어 고온상태인 코팅강관을 코팅강관 가열유니트와 단열통에 의해 단열공간을 형성할 수 있는 코팅강관 보온장치에 거치시키므로써 상기 코팅강관의 스스로의 잠열에 의해 강관과 강관에 코팅된 수지의 융착을 보다 견고히 할 수 있도록 하고, 또한 강관에 코팅된 수지의 표면에 광택을 줄 수 있도록 한 것이다.Unlike the conventional method, the present invention does not reheat the coated steel pipe by using a burner, but the steel pipe heated by the primary heating process of first heating the steel pipe in order to fuse the resin powder to the steel pipe maintains high temperature for a considerable time. Focusing on the point, the primary heated high-temperature coated steel pipe is mounted on a coated steel pipe thermostat that can form an insulating space by a coated steel pipe heating unit and a heat insulating tube so that the latent heat of the first heated coated steel pipe can be used as it is. By making the latent heat of the coated steel pipe by itself, it is possible to more firmly fusion of the resin coated on the steel pipe and the steel pipe, and also to give gloss on the surface of the resin coated on the steel pipe.

본 발명의 구성을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.The configuration of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명의 전체적인 구성을 보이기 위한 사시도를 도시한 것으로, 본 발명은 크게 반원통형상의 코팅강관 가열유니트(11)와 레일(12a)을 구비하는 틀체(12)를 구비하는 코팅강관 거치부(10)와, 상기 코팅강관 거치부(11)의 양단에 설치되는 레일(23a)을 구비하는 틀체(23)와 바퀴(21a)와 손잡이(22)를 구비하는 반원통형의 단열통(21)으로 구성된 코팅강관 보온부(20)로 구성된 것이다.1 is a perspective view for showing the overall configuration of the present invention, the present invention is a coated steel pipe mounting portion having a frame 12 having a semi-cylindrical coated steel pipe heating unit 11 and a rail (12a) (10) and a semi-cylindrical heat insulating tube (21) having a frame (23) having a rail (23a) provided at both ends of the coated steel pipe holder (11), and a wheel (21a) and a handle (22). It is composed of a coated steel pipe insulation portion 20 composed of.
상기 단열통(21)의 측면에는 투시창(24)을 형성하므로써 코팅강관(A)의 코팅작업정도를 작업자가 육안으로 확인할 수 있도록 하였고, 강관의 복사열에 의해 뜨거워진 단열통(21)으로 부터 작업자를 보호하기 위해 손잡이(22)는 단열통으로 부터 약간 이격되어 후방에 형성되어진다.By forming the see-through window 24 on the side of the heat insulating tube 21, the operator can visually check the coating work degree of the coated steel pipe (A), the worker from the heat insulating tube 21 heated by the radiant heat of the steel pipe To protect the handle 22 is formed at the rear and slightly spaced apart from the insulating tube.
따라서 상기 코팅강관(A)이 미도시된 코팅장치로 부터 본 발명 코팅강관거치부(10)에 옮겨지게 되면 작업자는 단열통(21)을 밀어 레일(23a)을 따라 이동시키므로써 코팅강관거치부(10)로 옮기게 되고, 결국 코팅강관 가열유니트(11)와 단열통(21)에 의해 원통의 단열공간(B)을 형성하게 된다.Therefore, when the coated steel pipe (A) is moved from the coating device not shown to the coating steel pipe mounting portion 10 of the present invention, the operator pushes the heat insulating tube 21 to move along the rail 23a, thereby coating the steel pipe mounting portion. It is moved to (10), and eventually forms a cylindrical heat insulating space (B) by the coated steel pipe heating unit 11 and the heat insulating cylinder (21).
상기와 같이 단열공간(B) 내부에 거치되어 있는 코팅강관(A)은 코팅강관 가열유니트(11)와 단열통(21)에 의해 외부와 차단된 상태가 되므로 코팅분말의 융착을 위해 버너로 1차 가열되어 고온의 상태를 유지하고 있는 코팅강관(A) 스스로의 잠열에 의해 코팅강관의 표면과 내면에 코팅되어 있던 수지가 좀더 견고하게 강관과 융착되어지고, 또한 상기 코팅강관 가열유니트(11)와 단열통(21)은 상기 코팅강관(A)에서 발산되는 열을 다시 코팅강관(A)으로 복사시키므로써 수지의 표면광택을 살릴 수 있도록 구성한 것이다.As described above, the coated steel pipe (A) mounted inside the heat insulating space (B) is cut off from the outside by the coated steel pipe heating unit 11 and the heat insulating tube 21, so as to burner for fusion of the coating powder. The resin coated on the surface and the inner surface of the coated steel pipe is more firmly fused with the steel pipe by the latent heat of the coated steel pipe A, which is gradually heated to maintain a high temperature, and the coated steel pipe heating unit 11 And the heat insulating tube 21 is configured to restore the surface gloss of the resin by radiating the heat emitted from the coated steel pipe (A) back to the coated steel pipe (A).
이처럼 본 발명은 종래처럼 버너를 사용하여 코팅강관을 재가열하는 것이 아니고, 코팅강관 가열유니트와 단열통에 의해 단열공간을 형성하고, 상기 단열공간 내에서 1차가열된 코팅강관의 스스로의 잠열에 의해 코팅강관과 수지와의 융착을 보다 견고히 하고, 수지표면에 광택을 줄 수 있는 효과를 갖는 것이다.As described above, the present invention does not reheat the coated steel pipe by using a burner as in the prior art, but forms an insulating space by the coated steel pipe heating unit and the insulating tube, and by the latent heat of the first-coated coated steel tube in the insulating space. The fusion between the coated steel pipe and the resin is more firm, and the surface of the resin can be glossed.
