이와 같이 구성된 본 발명에 대한 동작상태를 설명하면, 도 1 및 도 2a,2b에서와 같이 건설현장 등에서 발생되는 폐콘크리트, 폐아스콘 등의 건설폐기물을 수거하여 조크러셔(1)로써 1차적으로 파쇄한 다음, 적정 크기로 파쇄된 건설폐기물을 제1차선별장치(50) 내부로 공급하여 중량물과 경량물의 건출폐기물로 분리시키게 된다.Referring to the operating state of the present invention configured as described above, as shown in Figures 1 and 2a, 2b to collect the construction waste, such as waste concrete, waste ascon, etc. generated in the construction site, primarily crushed by the jaw crusher (1) Then, the construction waste crushed to an appropriate size is supplied into the first screening device 50 to be separated into the heavy and light weight construction waste.

즉, 이러한 제1차선별장치(50)의 폐기물유입구(53)를 통하여 1차로 파쇄된 건설폐기물(재생골재,토분,폐비닐,천,나뭇조각,플라스틱조각)이 유입됨과 동시에 하부의 송풍노즐(54)을 통하여 외부에서 강한 바람이 공급된다. That is, the construction wastes (recycled aggregate, soil, vinyl, cloth, wood chips, plastic chips), which are primarily crushed, are introduced through the waste inlet 53 of the first screening device 50, and at the same time, a blower nozzle at the bottom. Strong wind is supplied from outside through 54.

이에 따라 풍속으로 인하여 하부의 분기판(55)을 중심으로 건설폐기물중 중량물과 경량물이 중량물배출구(56)와 경량물배출구(57)로 배출이 이루어져 하부의 배출물컨베이어(60)를 통하여 제1차진동스크린(10)으로 공급된다.Accordingly, due to the wind speed, heavy weight and light weight of the construction wastes are discharged to the heavy weight discharge port 56 and the light weight discharge port 57 based on the branch plate 55 in the lower portion, and thus the first discharge conveyor 60 is discharged. It is supplied to the vehicle vibration screen (10).

이때, 건설폐기물에서 발생되는 먼지 등의 불순물이 내부 후방 영역의 네트필터(58)를 통과하여 걸러지게 되고, 이물질이 걸러진 공기는 배출구(59)를 통하여 외부로 배출된다.(도 3참조)At this time, impurities such as dust generated from construction waste are filtered through the net filter 58 in the inner rear region, and the filtered air is discharged to the outside through the discharge port 59 (see FIG. 3).

이와 같이 경량물과 중량물로 분리된 건설폐기물은 제1차진동스크린(10)의 자체 진동에 의해 적정 매쉬의 스크린을 순차적으로 하방으로 통과하면서 토분 등이 제1토분배출컨베이어(62)를 통하여 외부로 배출이 이루어지고, 토분 등이 걸려진 건설폐기물은 배출컨베이어(12)를 통해 제2차선별장치(70)로 공급되어 건설폐기물중 재생골재와 토분,폐비닐,천,나뭇조각,플라스틱조각의 이물질이 분리 배출된다.As such, the construction waste separated into light and heavy materials passes through the screen of the appropriate mesh sequentially by the self-vibration of the first vibration vibrating screen 10, while soil and the like are externally discharged through the first soil discharge conveyor 62. The construction wastes are discharged into the furnace, and the earthen wastes are hung, and are supplied to the second sorting device 70 through the discharge conveyor 12, and the recycled aggregates, soils, waste vinyl, cloth, wood chips, plastic pieces, etc. Foreign matters are separated and discharged.

도 4를 참조로 상세히 설명하면, 배출컨베이어(12)를 따라 이동되는 건설폐기물이 배출컨베이어(12) 상부 영역에 구비된 감지기(72)의 감지 영역으로 이동되면, 감지기(72)에서 적외선 등의 광원이 조사되어 공급되고 있는 폐기물의 종류를 감지하고, 이 감지된 신호를 제어부(74)로 전달하게 된다.Referring to FIG. 4, when the construction waste moved along the discharge conveyor 12 is moved to the detection area of the detector 72 provided in the upper area of the discharge conveyor 12, the detector 72 may emit infrared light. The light source is irradiated to detect the type of waste being supplied, and transmit the detected signal to the control unit 74.

그러면, 제어부(74)에서는 전달받은 신호와 자체 정보를 상호 비교판단한 다음, 폐기물의 종류에 따라 에어분출수단(A)의 에어 공급량을 조절하게 된다. Then, the controller 74 compares the received signal and the self information with each other, and then adjusts the air supply amount of the air ejecting means A according to the type of waste.

예컨대, 폐기물의 종류가 가벼운 폐비닐,천,나뭇조각,플라스틱조각 등이면 에어탱크(80) 내부의 에어량을 많이 공급시켜 에어분출구(82)를 통하여 많은 량의 에어를 분출시키게 된다. 이에 따라 폐비닐,천,나뭇조각,플라스틱조각이 쉽게 날리면서 분기판(86)을 타고 넘어 제1컨베이어(87)로 공급되어 외부로 배출이 이루어진다.For example, if the type of waste is light waste vinyl, cloth, wood chips, plastic pieces, etc., a large amount of air is supplied in the air tank 80 to eject a large amount of air through the air ejection port 82. Accordingly, the waste vinyl, cloth, wood chips, plastic pieces are easily blown off and flown through the branch plate 86 to the first conveyor 87 to be discharged to the outside.

그리고, 무거운 폐기물(재생골재)이 공급되면, 에어탱크(80) 내부의 에어를 적게 공급하거나 중단시켜 에어분출구(82)를 통해 적게 분출시키거나 차단하게 됨으로써 자체 중량에 의해 제2컨베이어(88)로 낙하하여 다른 공정, 즉 더블조 크러셔(20)로 공급되어 2차로 분쇄가 이루어지고, 더블죠 그라셔(20)의 하부영역에 구비된 제1배출컨베이어(89)를 통하여 이물질이 분리된 2차로 파쇄된 폐기물이 제2진동스크린(30)으로 공급된다. Then, when heavy waste (recycled aggregate) is supplied, the second conveyor (88) by its own weight by supplying or interrupting less air in the air tank (80) to eject or block less through the air outlet (82) 2 to which the foreign matter is separated through the first discharge conveyor 89 provided in the lower region of the double jaw crusher 20 by being supplied to another process, that is, supplied to the double jaw crusher 20 and falling to the second zone. The waste shredded into the car is supplied to the second vibration screen 30.

이와 같이 제2차진동스크린(30)으로 공급된 폐기물은 자체 진동에 의해 적정 매쉬의 스크린을 순차적으로 하방으로 통과하면서 폐기물에 포함된 토분 등이 제2토분컨베이어(63)를 통하여 외부로 배출되고, 토분이 2차로 걸러진 폐기물은 제2배출컨베이어(90)를 통해 다시 공급되어 임팩트 크러셔(40)에서 파쇄하여 적정 크기 재생골재를 생성한 다음, 하부 영역에 구비된 제3배출컨베이어(91)를 통하여 외부로 배출시킴으로써 한 공정이 완료되어 다음 공정을 대기하게 된다.As such, the waste supplied to the second vibrating screen 30 sequentially passes downward through the screen of the appropriate mesh by its own vibration, and the soil powder contained in the waste is discharged to the outside through the second soil powder conveyor 63. The wastes filtered by the second soil are supplied again through the second discharge conveyor 90 to be crushed in the impact crusher 40 to generate the recycled aggregate of the appropriate size, and then the third discharge conveyor 91 provided in the lower region is removed. By discharging to the outside, one process is completed and the next process is waited.
