Description

합성수지관의 내경 냉각방법 및 그 장치{a}Internal diameter cooling method of synthetic resin pipe and device therea {a}

본 발명은 주로 합성수지관을 나선형으로 성형하기 위한 프로파일의 성형과정에서 프로파일의 내부 공간에 냉각공기를 공급하여 성형된 프로파일이 신속하게 냉각되도록 하는 합성수지관의 내경 냉각방법 및 그 장치에 관한 것이다.The present invention mainly relates to an internal diameter cooling method of a synthetic resin tube and a device for supplying cooling air to the inner space of the profile in the process of forming the profile for spirally forming the synthetic resin tube so that the molded profile is cooled quickly.

종래 합성수지관은 내부에 사각형 또는 원형의 구멍이 하나가 성형되는 프로파일을 공급하여 이중벽 하수관을 제조하며, 사각형의 내부에 열십자형으로 보강대가 형성되어 있어서 4개의 구멍이 성형되는 프로파일을 공급하여 복합관을 성형한다.Conventional synthetic resin pipe is a double-walled sewer pipe is produced by supplying a profile in which one of the square or circular holes are formed therein, and a reinforcing rod is formed in a cross shape in the quadrangle to supply a profile in which four holes are formed. Mold.

상기 프로파일은 노즐몸체(22)에서 성형된 후 진공상태 또는 수냉과정을 통하여 냉각된 후 나선형으로 와인더에 공급되어 관을 성형하게 된다.The profile is molded in the nozzle body 22 and then cooled through a vacuum or water cooling process and then spirally supplied to the winder to form a tube.

그러나 노즐몸체에서 성형된 프로파일은 내부가 중공상태이나 외부에서 공급되는 냉각방법으로는 잘 냉각되지 않아서 내부의 성형 상태가 무너지게 되어 강도를 제대로 유지할 수 없는 결점이 있었다.However, the profile formed in the nozzle body has a drawback in that the inside is not cooled well by the cooling method supplied from the hollow state or the outside, so that the molded state of the inside collapses and the strength cannot be properly maintained.

또한 신속하게 냉각되지 못하므로 프로파일의 공급속도가 늦어지게 되어 관의 성형속도를 낼 수 없어서 생산성이 저하되므로 생산성을 향상시키기 위해서는 프로파일을 성형한 상태를 유지하면서 냉각된 프로파일을 빠른 속도로 공급하는 것이다.In addition, because the cooling rate cannot be rapidly cooled, the feed rate of the profile is slowed down, and thus, the molding rate of the tube cannot be achieved, and thus the productivity is reduced. .

본 발명은 이러한 종래의 결점을 해소시키기 위하여 안출된 것으로, 1차 냉각장치에서 냉매를 이용하여 냉각된 공기를 공급하는 과정에서 자연공기를 흡입하고 벤츄리의 원리를 이용한 2차 냉각조절장치를 통하여 냉각된 공기를 프로파일의 내경에 공급함으로써 급속한 냉각이 이루어지도록 하는 것이다.The present invention has been made to solve the above-mentioned drawbacks, the intake of natural air in the process of supplying the cooled air using the refrigerant in the primary cooling device and cooling through the secondary cooling control device using the principle of Venturi Rapid cooling is achieved by supplying the compressed air to the inner diameter of the profile.

본 발명은 하측으로 냉매입구(2)와 냉매배출구(3)가 각각 형성된 1차 냉각장치(1)의 중앙으로 공기 입력구(4)가 설치되어 있다.In the present invention, the air input port 4 is provided at the center of the primary cooling device 1 in which the coolant inlet 2 and the coolant outlet 3 are respectively formed.

1차 냉각장치(1)에서는 연결호스(5)가 냉각파이프(7)와 연결되어 있어서 냉각된 냉매를 공급할 수 있도록 한다.In the primary cooling device 1, the connection hose 5 is connected to the cooling pipe 7 to supply the cooled refrigerant.

상기 연결호스(5)와 냉각파이프(7)의 연결부분에는 밸브(10)와 압력계(11) 및 온도계(12)가 설치되어 있어서 컨트롤 박스(25)를 통하여 제어되도록 설치한다.The connection portion of the connection hose 5 and the cooling pipe 7 is provided with a valve 10, a pressure gauge 11, and a thermometer 12 to be controlled through the control box 25.

상기 냉각파이프(7)에는 외부의 자연공기 흡입구(8)의 공기를 흡입하는 양을 제어하는 밸브(9)가 컨트롤 박스(25)를 통하여 제어되도록 하며, 자연공기 흡입구(9)와 냉각파이프(7)의 연결부분에는 냉매가 공급되면서 벤츄리의 원리를 이용한 2차 냉각조절장치(6)가 설치되어 있다.The cooling pipe 7 has a valve 9 for controlling the amount of intake air from the external natural air intake port 8 to be controlled through the control box 25, the natural air intake port 9 and the cooling pipe ( At the connection part of 7), the secondary cooling control device 6 using the principle of Venturi is installed while the refrigerant is supplied.

냉각파이프(7)의 일측으로 연결호스(16)를 연결하되 밸브(13)와 압력계(14) 및 온도계(15)가 설치되어 있다.A connection hose 16 is connected to one side of the cooling pipe 7, but a valve 13, a pressure gauge 14, and a thermometer 15 are installed.

상기 연결호스(16)는 헤드(18)와 노즐몸체(22)의 중앙을 관통하는 공기 공급파이프(19)에 연결되어 있다.The connecting hose 16 is connected to an air supply pipe 19 passing through the center of the head 18 and the nozzle body 22.

상기 공기 공급파이프(19)는 냉매와 헤드(18)간에 온도를 차단하기 위하여 도색하는 방법을 통하여 온도가 차단되도록 한다.The air supply pipe 19 allows the temperature to be cut off by a method of painting to cut off the temperature between the refrigerant and the head 18.

상기 헤드(18)는 약200℃의 온도로 상승되며 일측으로 합성수지를 용융시켜공급하는 합성수지 공급부(17)가 연결된다.The head 18 is raised to a temperature of about 200 ℃ and the synthetic resin supply unit 17 for melting and supplying the synthetic resin to one side is connected.

합성수지 공급부(17)와 연결되는 합성수지 공급공(21)은 헤드(18)의 내부에서 좁아진 상태로 출발하여 넓어져서 절반정도 진행하다가 다시 더 넓어진 상태를 유지한 후 노즐몸체(22)에서 좁아지는 노즐공(23)과 연결된다.The synthetic resin supply hole 21 connected to the synthetic resin supply unit 17 starts in a narrowed state inside the head 18 and widens and proceeds about half, and then maintains a wider state, and then narrows the nozzle in the nozzle body 22. Is connected to the ball (23).

상기 노즐몸체(22)의 노즐공(23)에서는 원하는 형태의 프로파일(24)을 압출하고, 프로파일(24)의 중공부에 공기 공급 파이프(19)의 선단에 설치된 냉각공기 노즐(20)을 통하여 냉각되도록 하는 것이다.In the nozzle hole 23 of the nozzle body 22, a profile 24 having a desired shape is extruded, and through the cooling air nozzle 20 provided at the tip of the air supply pipe 19 in the hollow portion of the profile 24. To cool.

상기 냉각공기 노즐(20)은 중앙에 설치하지 않고 외측으로 경사지게 적어도 2개 이상 설치하여 장방형으로 배출되도록 하는 것이다.The cooling air nozzle 20 is installed at least two to be inclined to the outside without being installed in the center to be discharged in a rectangular shape.

상기 공기공급 파이프(19)는 중앙에 하나가 설치되는 경우가 있으나, 열십자형의 보강대가 형성된 프로파일(24)의 경우에는 4개의 중공이 형성되므로 각각의 중공에 공기공급 파이프(19)와 냉각공기 노즐(20)이 설치되는 것이다.One air supply pipe 19 may be installed at the center, but in the case of the profile 24 having a reinforcing bar having a cross shape, four hollows are formed, so that each air supply pipe 19 and cooling air are formed in each hollow. The nozzle 20 is installed.

이러한 구성으로 이루어진 본 발명은 냉매입구(2)를 통하여 물이나 냉매가스를 공급하여 1차 냉각장치(1)에서 공기 흡입구(4)로 흡입되는 공기를 냉각시킨 냉매를 연결호스(5)에 공급하게 된다.The present invention having such a configuration supplies water or refrigerant gas through the refrigerant inlet (2) to supply the refrigerant for cooling the air sucked into the air inlet (4) from the primary cooling device (1) to the connection hose (5). Done.

연결호스(5)에 공급되는 냉매는 냉각파이프(7)에 공급되는 것으로, 밸브(10)와 압력계(11) 및 온도계(12)를 컨트롤 박스(25)에서 제어하여 설정된 양의 냉매가 냉각파이프(7)에 공급되도록 한다.The refrigerant supplied to the connection hose 5 is supplied to the cooling pipe 7, and the amount of refrigerant set by controlling the valve 10, the pressure gauge 11, and the thermometer 12 from the control box 25 is stored in the cooling pipe. To (7).

냉각파이프(7)는 자연공기 흡입구(8)를 통하여 흡입되는 자연공기는 밸브(9)를 통하여 제어되면서 냉각파이프(7)에 공급될 때 2차 냉각조절장치(6)에서 벤츄리의 원리를 이용하여 냉매를 공급하게 된다.The cooling pipe 7 uses the Venturi principle in the secondary cooling regulator 6 when the natural air sucked through the natural air inlet 8 is supplied to the cooling pipe 7 while being controlled through the valve 9. To supply the refrigerant.

냉각파이프(7)를 통하여 공급되는 냉매는 밸브(10, 13)와 압력계(11, 14) 및 온도계(12, 15)를 통하여 원하는 온도의 냉매를 공급할 수 있게 된다.The refrigerant supplied through the cooling pipe 7 may supply the refrigerant of a desired temperature through the valves 10 and 13, the pressure gauges 11 and 14, and the thermometers 12 and 15.

연결호스(16)로 공급되는 냉매는 공기 공급파이프(19)를 통하여 선단의 냉각공기 노즐(20)에서 장방형으로 분사되어 프로파일(24)의 중공인 내경을 냉각시키는 것이다.The refrigerant supplied to the connection hose 16 is ejected in a rectangular shape from the cooling air nozzle 20 at the tip through the air supply pipe 19 to cool the inner diameter of the hollow of the profile 24.

이때 합성수지 공급부(17)에서는 합성수지 원료를 공급하여 용융시킨 후 합성수지 공급공(21)으로 공급하면 헤드(18)를 통과하면서 충분하게 혼합된 상태로 공급되다가 노즐몸체(22)에서 외경이 좁아지면서 노즐공(23)에서 중공상태의 프로파일(24)이 압출되는 것이다.In this case, the synthetic resin supply unit 17 supplies the synthetic resin raw material and melts it, and then, when supplied to the synthetic resin supply hole 21, is supplied in a sufficiently mixed state while passing through the head 18, and the nozzle body 22 has a narrow outer diameter. The hollow profile 24 is extruded from the ball 23.

상기 프로파일(24)의 내경에는 냉각공기 노즐(20)에서 방사상으로 냉매가 공급되므로 프로파일(24)의 내경을 신속하게 냉각시켜 압출된 상태를 그대로 유지할 수 있는 것이다.Since the coolant is radially supplied from the cooling air nozzle 20 to the inner diameter of the profile 24, the inner diameter of the profile 24 is rapidly cooled to maintain the extruded state.

상기 노즐몸체(23)는 헤드(19)와 교환이 가능한 것으로, 노즐공(23)이 사각형으로 이루어지는 경우에는 도 3 과 같이 사각형의 프로파일(24)이 성형되는 것이므로 중앙에 공기 공급파이프(19)가 설치된다.The nozzle body 23 is interchangeable with the head 19. When the nozzle hole 23 is formed in a quadrangle, since the rectangular profile 24 is molded as shown in FIG. 3, the air supply pipe 19 is formed at the center thereof. Is installed.

그러나 노즐공(23)이 중앙에 열십자형의 보강대가 형성되는 도 4 와 같이 사각형의 프로파일(24)로 성형되는 경우에는 중공이 4개가 형성되어 있으므로 공기 공급파이프(19)가 4곳에 각각 설치되어 있어서 냉각공기 노즐(20)이 4곳에서 냉매를 공급하게 된다.However, when the nozzle hole 23 is formed into a rectangular profile 24 as shown in FIG. 4 in which a cross-shaped reinforcement is formed in the center, four hollows are formed, and thus, the air supply pipes 19 are respectively provided at four locations. In this case, the cooling air nozzle 20 supplies the refrigerant at four locations.

상기 공기공급 파이프(19)는 헤드(18)와 노즐몸체(22)가 약200℃정도로 상승하게 되므로 냉매의 온도를 외부에 빼앗길 수 있으나, 외부에 온도를 차단할 수 있도록 특수 페인트를 2∼3회 수행하여 온도를 빼앗기지 않도록 하였다.The air supply pipe 19 is the head 18 and the nozzle body 22 is raised to about 200 ℃, so the temperature of the refrigerant can be taken away from the outside, but the special paint 2 to 3 times to block the temperature outside To prevent the temperature from being taken away.

본 발명은 프로파일(24)에 대하여 설명하였으나, 프로파일 이외에도 합성수지를 포함한 냉매가 사용 가능한 모든 생산설비에 적용할 수 있으므로 용도의 변경에도 불구하고 동일한 권리로 인정할 수 있다.Although the present invention has been described with respect to the profile 24, it can be recognized as the same right in spite of a change in the use, because the refrigerant can be applied to all the production equipment, including the synthetic resin in addition to the profile.

본 발명은 냉매를 공급하여 냉각장치에서 외부의 공기를 냉각시킨 냉매를 생성시켜 공급하는 과정에서 자연공기를 흡입하여 벤츄리의 원리를 이용한 냉매를 공급할 수 있는 것이다.The present invention can supply the refrigerant using the principle of Venturi by sucking the natural air in the process of generating and supplying the refrigerant to cool the outside air in the cooling device by supplying the refrigerant.

본 발명은 벤츄리의 원리를 이용하여 공급되는 냉매가 헤드의 내부를 관통하면서 헤드에서 발생되는 고온에도 온도를 빼앗기지 않고 노즐에서 프로파일의 중공 내경에 공급되어 프로파일이 성형된 상태를 유지하면서 냉각시킬 수 있는 것이다.According to the present invention, the refrigerant supplied through the inside of the head is penetrated through the inside of the head and is cooled to the hollow inner diameter of the profile from the nozzle without being deprived of temperature even at a high temperature generated from the head, thereby maintaining the profile in a molded state. will be.
