따라서 통기공간에 구비된 컨베이어(22)상에 폐스티로폼을 이동시키면서 간접열인 자외선 열을 통해 스치로폼을 건조시킴으로서, 폐스치로폼에 함유된 수분을 완전 증발 배출시켜 수분을 제거할 수 있는 것이다.Therefore, by drying the styrofoam through indirect heat while moving the waste styrofoam on the conveyor 22 provided in the ventilation space, the moisture contained in the waste styrofoam can be completely evaporated and discharged to remove the moisture.
또한, 상기 적외선 가열과정(20)의 전 과정으로 분쇄된 폐스티로폼을 이중롤러(31)를 통해 압축하여 폐스티로폼에 함유된 수분을 제거하는 과정(30)을 진행시킴에 따라서, 적외선 가열 전에 폐스티로폼을 압착하여 수분을 제거할 수 있는 것이다.In addition, by compressing the waste styrofoam pulverized in the entire process of the infrared heating process 20 through the double rollers 31 to remove the water contained in the waste styrofoam (30), waste before the infrared heating Styrofoam can be pressed to remove moisture.
또 상기 적외선 가열과정(20)후 축소된 부피로 배출되는 수지를 2중의 롤러(411)로 압축하여 수지판을 제조하면서 이 수지판을 다수의 커팅,압착롤러로 압착 커팅하여 원료가 되는 수지입자를 제조하는 수지입자 제조과정(40)을 진행시킴에 따라서, 적외선 가열부(2)에서 배출되는 수지판을 수지성형의 원료가 되는 수지입자로 파쇄 배출할 수 있는 것이다.In addition, the resin discharged in a reduced volume after the infrared heating process 20 is compressed with a double roller 411 to produce a resin plate, and the resin plate is pressed and cut with a plurality of cutting and pressing rollers, thereby producing resin particles. As the resin particle manufacturing process 40 proceeds, the resin plate discharged from the infrared heating unit 2 can be crushed and discharged into resin particles which become the raw material for resin molding.
상술한 바와 같이 본 발명은, 폐스치로폼에 포함된 수분을 간접열을 통해 완전히 증발 통기시킴에 따라 폐스티로폼의 잔류수분으로 인하여 발생되는 재생수지의 불량을 막음으로서, 수분이 함유된 폐스티로폼 재생을 가능하게 하는 효과를 가지는 것이다.As described above, the present invention, by completely evaporating the moisture contained in the waste styrofoam through indirect heat to prevent the defect of the recycled resin caused by the residual moisture of the waste styrofoam, to prevent the waste styrofoam regeneration containing water It has the effect of making it possible.
또 적외선 가열부에서 배출되는 수지를 단일의 라인에서 판형으로 압연한 후 이를 수지입자로 파쇄함으로서, 감융후 별도의 파쇄공정으로 인하여 발생되는 생산성저하와 비용의 낭비를 막을 수 있는 효과도 있다.In addition, by rolling the resin discharged from the infrared heating unit into a plate shape in a single line and then crushing the resin into resin particles, it is possible to prevent the decrease in productivity and waste of cost caused by the separate crushing process after melting.
또한 적외선 가열 전에 폐스티로폼을 압착하여 수분을 제거함에 따라 적외선 가열을 통한 건조 압축의 효율을 높임으로서, 수분이 함유된 폐스티로폼의 재생효율을 극대화 할 수 있는 효과도 있다.In addition, by compressing the waste styrofoam before infrared heating to increase the efficiency of the dry compression through the infrared heating, there is also an effect to maximize the regeneration efficiency of the waste styrofoam containing moisture.
본 발명은 도면에 도시된 실시예를 참고로 설명되었으나 이는 예시적인 것에 불과하며, 당해 기술분야에 통상의 지식을 지닌 자 라면 이로부터 다양한 변형 및 균등한 타실시예가 가능하다는 점을 이해할 것이다.Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible therefrom.
