Description
본 고안은 합성수지제 이중벽하수관 및 그 제조장치에 관한 것으로, 더욱 구체적으로는 중공부를 가진 소형관을 나선형으로 감아 관체를 형성하고 그 관체의 나선부 간극부분에 액상의 합성수지를 주입시켜 형성되는 합성수지접합층으로 일체로 접합연결된 관체의 표면이 매끄럽고 연질 및 내후성이 좋은 합성수지 피복층이 형성되어 내구성이 크게 향상된 이중벽하수관및 그 제조장치에 관한 것이다.The present invention relates to a double wall sewage pipe made of synthetic resin and a manufacturing apparatus thereof. More specifically, a synthetic resin joint formed by spirally winding a small pipe having a hollow part to form a tube, and injecting a liquid synthetic resin into a spiral gap portion of the tube. It relates to a double wall sewer pipe and a device for manufacturing the same, in which a synthetic resin coating layer having a smooth, soft and weather resistant surface is formed with a smoothly joined surface connected to each other in layers.
일반적으로 합성수지재를 재료로 쓰는 하수관 제조에서는 변형과 파괴에 대비하고 적절한 강도를 부여하기 위해서 강도가 크면서 가볍고 재료를 적게 쓰면서 관을 제조하는데 주안점을 두고 있다.In general, sewage pipe manufacturing using synthetic resin materials is focused on manufacturing pipes with high strength, light weight, and low material in order to prepare for deformation and breakdown and to give adequate strength.
그래서 종래에도 도 2와 같이 압출기(20)를 통해 압출성형되어 나온 중공부를 가진 소형관(12)이 냉각성형장치(22)와 냉각고형화장치(24)를 성형냉각시킨다음 다수의 롤러(28a)가 원주상으로 구비된 드럼(28)을 따라 일정하게 감겨진다Thus, a small tube 12 having a hollow portion extruded through the extruder 20 as shown in FIG. 2 is formed to cool the cooling molding apparatus 22 and the cooling solidifying apparatus 24, and then a plurality of rollers 28a. Is constantly wound along the circumferentially provided drum 28
이렇게 소형관(12)이 드럼(28)에 감기는 접합대상 간극 사이에는 접합력을 높이기 위해 온풍공급기(31)에 의해 열풍을 불어주어 소형관(12)의 접합면이 접합용수지와 쉽게 접합될수 있는 적정온도로 접합조건을 갖춘 상태에서 접합용 액상의 수지가 간극사이에 주입됨과 아울러 접착롤러(32)에 의해 압착되게 함으로서 소형관(12)이 접합용수지에 의해 나선형으로 접합된 관체(10)로 이중벽하수관을 구성하게 된다.Thus, the hot air is blown by the hot air supplier 31 to increase the bonding force between the gaps to be joined to the drum 28 by the small pipe 12 so that the joint surface of the small pipe 12 can be easily joined with the resin for bonding. The pipe 10 in which the small pipe 12 is spirally joined by the bonding resin by injecting the liquid resin for bonding into the gaps and being pressed by the adhesive roller 32 in a state where the bonding conditions are at a proper temperature. ), The double wall sewer pipe is constructed.
즉, 상기와 같은 제조장치에 의해 제조되어 나온 이중벽하수관의 관체는 내력강도를 높이기 위해 소형관(12)이 나선형으로 감긴 형태로 그 소형관(12)과 거의 같은 재질의 접합용수지가 사용되어 일체감을 갖도록되어 있기 때문에 내력강도는 유지할수 있었으나 운반 및 설치과정에서의 외부 충격에 약할 뿐만 아니라 햇빛등에 의해 쉽게 갈라지게 되었으며, 특히 소형관성형시에 재활용수지원료를 사용하는 경우에 많은 문제점이 있었다.That is, the pipe of the double wall sewage pipe manufactured by the manufacturing apparatus as described above has a shape in which the small pipe 12 is spirally wound in order to increase the strength strength, and the bonding resin of the same material as that of the small pipe 12 is used. Since the strength was maintained, it was not only susceptible to external impacts during transportation and installation, but also easily broken by sunlight. In particular, there was a lot of problems when using recycled water support fees for small inertia molding.
또한, 소형관(12)의 나선간극부분에 액상의 접합부분을 접착롤러로 압착시키는 과정에서 나선형홈이 발생하는 등 표면이 고르지 못하여 내구성이 크게 떨어지게 되었다.In addition, in the process of pressing the liquid bonding portion to the spiral gap portion of the small tube 12 with an adhesive roller, such as a spiral groove is generated, the surface is uneven, so durability is greatly reduced.
본 고안은 이러한 문제점을 해결하기 위하여 소형관을 나선형으로 감아 관체를 형성하고 그 관체의 나선부간극 부분을 액상의 합성수지로 접합시켜 일체로 된 관체의 표면에 연질 및 내후성을 지닌 합성수지피복층이 형성된 구성으로 되어 있고 상기 피복층은 접합수지공급부에서 관체의 나선부 간극부분에 접합수지를 주입하고 접착롤러에 의해 액상의 합성수지를 접합시켜 나오는 진행방향에 피복수지공급부와 압착롤러가 설치되어 연질 및 내후성을 갖는 피복층을 형성시킬수 있도록 되어 있는 합성수지제 이중벽하수관 및 그 제조장치를 제공함에 있다.In order to solve this problem, the present invention forms a tubular body by spirally winding a small tube, and joins the spiral gap portion of the tubular body with a liquid synthetic resin to form a synthetic resin coating layer having soft and weather resistance on the surface of the integrated tube. The coating layer is formed by injecting the bonding resin into the gap portion of the spiral portion of the pipe from the bonding resin supplying unit, and coating the coating resin supplying unit and the pressing roller in the advancing direction to bond the liquid synthetic resin by the adhesive roller to provide soft and weather resistance. The present invention provides a double wall sewage pipe made of synthetic resin, and a manufacturing apparatus thereof, capable of forming a coating layer.

특히, 폐합성수지를 재활용하여 만들어진 소형관(12)을 압출성형하여 이중벽하수관을 성형하더라도 본 고안의 피복층(18)에 의해 내구성을 좋게 하므로 상품 수명을 크게 연장시킬수 있게 된다.In particular, the compact pipe 12 made by recycling waste synthetic resin is extruded to form a double wall sewage pipe, thereby improving durability by the coating layer 18 of the present invention, thereby greatly extending product life.
그리고 이러한 이중벽하수관의 제조장치는, 압출기(20)와 냉각성형장치(22), 냉각고형화장치(24)를 거쳐 중공부를 가진 소형관(12)이 성형냉각되고 가이드롤러(26)를 따라 소형관(12)이 다수의 롤러(28a)가 원주상으로 구비된 드럼(28)을 따라 나선형으로 일정하게 감겨져서 관체(10)가 형성되는 드럼(28)상측에 보조압출기가 구비된 접합수지공급부(30)가 설치되어 액상의 합성수지를 주입할수 있게 되어 있고 접합수지공급부(30)에서 소형관(12)의 나선공급방향으로 온풍공급을 하는 온풍공급기(31)와 드럼(38)의 외부에 액상의 합성수지를 간극사이에 접착하는 접착롤러(32)가 설치되며 소형관(12)을 나선형으로 감은 관체(10)의 나선부 간극부분을 액상의 합성수지로 접합시켜 나오는 진향방향의 드럼(28)상측에 보조압출기가 구비된 피복수지공급부(34)가 설치되어 연질 및 내후성을 가진 액상의 합성수지를 도포시키고 드럼(28)일측에 압착롤러(36)가 설치되어 표면을 압착시켜 소정두께로 형성시킬수 있도록 되어 있다.The double wall sewage pipe manufacturing apparatus includes an extruder 20, a cooling molding device 22, a cooling solidifying device 24, and a small pipe 12 having a hollow portion formed by cooling and a small pipe along the guide roller 26. A joint resin supply unit (12) is provided with an auxiliary extruder on the drum (28) on which a plurality of rollers (28a) is helically wound along a drum (28) having a circumferential shape so that the tubular body (10) is formed ( 30 is installed to inject a liquid synthetic resin and the liquid on the outside of the hot air supply 31 and the drum 38 to supply hot air in the spiral supply direction of the small pipe 12 in the joint resin supply unit 30 An adhesive roller 32 is installed to bond the synthetic resin between the gaps. The spiral gap portion of the tubular body 10 spirally wound around the small tube 12 is joined to the drum 28 in the forward direction, which is joined by a liquid synthetic resin. Coated resin supply unit 34 is provided with a sub-extruder By applying a liquid synthetic resin with the quality and weather resistance and the pressure roller 36 at a side drum (28) it is provided a compression bonding surface is to sikilsu formed to a desired thickness.
즉, 도6에서와 같이 소형관(12)이 드럼(28)에 나선형으로 감기면서 관체(10)가 형성되고 그 관체(10)의 나선부 간극(14)부분은 드럼(28)상측에 설치된 접합수지공급부(30)에서 액상의 합성수지가 주입이 이루어진 다음 드럼(28)회전에 의해서 접착롤러(32)에 도달하게 되면 접착롤러(32)에 의해 소형관(12)이 서로 접합되면서 관체(10)를 구성하게 된다.That is, as shown in FIG. 6, the tubular body 10 is formed while the small tube 12 is spirally wound on the drum 28, and the spiral gap portion 14 of the tubular body 10 is provided above the drum 28. When the synthetic resin in the liquid phase is injected from the joint resin supply unit 30 and reaches the adhesive roller 32 by rotating the drum 28, the small pipes 12 are joined to each other by the adhesive roller 32 and thus the tubular body 10 is connected. ).
이렇게 연속적으로 관체(10)가 접합되어 나오는 동안에 드럼(28)상측에 위치한 피복수지공급부(34)에서 연질및 내후성을 지닌 액상의 합성수지가 이중벽하수관(10)표면에 도포되어 압착롤러(36)에 의해 표면을 소정두께로 고르게 만들어 주게 되며 이어서 냉각수등의 냉각공정을 거쳐 성형이 완료된다.While the pipe body 10 is continuously joined in this way, a liquid synthetic resin having soft and weather resistance is coated on the surface of the double wall sewer pipe 10 in the coated resin supply part 34 located above the drum 28, and then pressed onto the pressing roller 36. This makes the surface even to a predetermined thickness, and then molding is completed through a cooling process such as cooling water.
이상에서 본 고안은 상기 실시예를 참고하여 설명하였지만 본 고안의 기술사상범위내에서 다양한 변형실시가 가능함은 물론이다.Although the present invention has been described with reference to the above embodiment, various modifications are possible within the technical scope of the present invention.
이와같이 본 고안의 이중벽하수관 및 그 제조장치는 중공부를 가진 소형관이 나선형으로 감아 형성되는 관체의 나선부 간극부분에 액상의 합성수지가 주입되어 일체로된 관체가 형성되고 그 관체의 표면에 연질및 내후성이 좋고 합성수지피복층이 형성되어 내구성을 크게 향상시킬수 있게 된다.As described above, the double wall sewage pipe and the manufacturing apparatus of the present invention are formed by injecting a liquid synthetic resin into the spiral gap portion of the tubular body in which a small tube having a hollow part is spirally wound to form an integrated tubular body, and the surface of the tubular body is soft and weather resistant.
