건설폐기물의 이물질 선별장치{Apparatus for sorting waste from construction waste matter}Apparatus for sorting waste from construction waste matter}

본 발명은 건설폐기물의 이물질 선별장치에 관한 것으로, 보다 구체적으로는 건설폐기물을 유용한 자원으로 재활용하기 위한 건설폐기물 중간처리과정에서, 건설폐기물에 혼재되어 있는 비닐, 종이, 천조각, 폐플라스틱 또는 스티로폼과 같은 각종 이물질을 효율적으로 선별 추출하는 건설폐기물의 이물질 선별장치에 관한 것이다.The present invention relates to a foreign matter sorting device for construction waste, more specifically, in the construction waste intermediate process for recycling the construction waste as a useful resource, vinyl, paper, scrap, waste plastic or styrofoam mixed in the construction waste The present invention relates to a foreign matter sorting device for construction wastes, which efficiently screens and extracts various foreign matters.

친환경적 측면 및 자원의 재활용 측면에서 건설 및 건축 구조물의 해체시에 발생하는 폐기물은 매립되지 않고 소정의 장소로 수집된 후 파쇄공정, 이물질 선별공정, 재생골재와 모르타르 분리공정 및 재생골재 표면에 부착된 모르타르 박리공정등 일련의 중간처리과정을 통해 양질의 자원으로 생산되고 있다. In terms of eco-friendliness and recycling of resources, wastes generated during the dismantling of construction and building structures are collected in a predetermined place without being landfilled, and then crushed, debris sorting, separation of recycled aggregates and mortar, and attached to the surface of recycled aggregates. It is produced with high quality resources through a series of intermediate processes such as mortar stripping process.

일련의 중간처리과정 중 이물질 선별공정을 좀 더 설명보면, 이물질 중 금속 재는 전자석 자선기에 의해 부착 제거되기 때문에 선별 및 제거에 특별한 문제는 없으나, 비닐, 종이 또는 스티로폼과 같은 비교적 비중이 적은 이물질의 경우에는 직접 육안으로 확인하면서 이물질을 수작업으로 선별 제거하여야 했기 때문에 선별작업이 불편할 뿐만 아니라 많은 시간이 소요되었다. 이에, 당업계에서는 비닐, 종이 또는 스티로폼과 같은 비교적 비중이 적은 이물질의 선별 및 제거방법에 다양한 연구를 수행하고 있으며, 이에 풍력을 이용한 선별제거방식과 수조를 이용한 선별제거방식이 대안으로 제시되고 있다.When explaining the foreign matter sorting process in a series of intermediate processes, there is no particular problem in sorting and removing because the metal ash among the foreign matters is attached and removed by the electromagnet charity, but in the case of the relatively small foreign matter such as vinyl, paper or styrofoam. In addition, screening was not only inconvenient but also required a lot of time because the foreign matter had to be manually removed while checking with the naked eye. Therefore, in the art, various studies have been conducted on the method of screening and removing foreign matters having a relatively low weight such as vinyl, paper, or styrofoam, and the screening method using wind power and the tank screening method have been proposed as alternatives. .

여기서, 수조이용 선별제거방식은 수조 내로 건설폐기물을 통과시켜 건설폐기물에 혼재되어 있는 이물질을 물위로 부상하게 한 후 별도의 채집장치를 이용하여 이물질을 선별 제거하는 방식을 말하는 것으로, 이와 관련된 많은 발명 및 고안이 개시되어 있다.Here, the sorting removal method using the water tank refers to a method of sorting and removing foreign matters by using a separate collecting device after allowing the foreign matter mixed in the construction wastes to float on the water by passing the construction waste into the water tank. And the invention are disclosed.

일례로, 대한민국 특허 등록 제557493호에는 파분쇄된 건설폐기물의 이물질 선별장치가 개시되어 있다. 이를 보면, 도 1에 도시된 바와 같이, 건설폐기물의 재활용 처리 시스템 중 파쇄와 선별과정을 거친 골재가 투입되어 이물질이 세척되도록 하는 세척수조를 포함하는 파분쇄된 건설폐기물의 이물질 선별장치에 있어서, 상기 세척수조의 일측에 일부분이 잠기며 구동수단에 의해 회전하면서 상기 세척수조에 부유하는 이물질을 물과 함께 외부로 퍼내어 제거하는 이물질 제거수차와; 상기 이물질 제거수차의 직하부에 설치되어 상기 이물질 제거수차에 의해 배출되는 세척수와 이물질을 분류하는 이물질 선별스크린과; 상기 이물질 선별스크린의 배출단 하부에 설치되어 상기 이물질 선별스크린에 의해 배출되는 이물질을 중량별로 선별하는 송풍기로 구성된다.For example, Korean Patent Registration No. 574953 discloses a foreign matter sorting device for crushed construction waste. As shown in FIG. 1, in the waste sorting apparatus of crushed construction waste including a washing water tank in which aggregates which have undergone crushing and screening processes are recycled in the recycling system for construction wastes, the foreign substances are washed. A foreign substance removal aberration which is partially locked to one side of the washing tank and rotates by a driving means to remove the foreign matter floating in the washing tank with water to remove it; A foreign matter sorting screen installed under the foreign matter removing aberration to classify the cleaning water and foreign matter discharged by the foreign matter removing aberration; It is installed at the lower end of the discharge screen of the foreign matter sorting screen is composed of a blower for sorting the foreign matter discharged by the foreign matter sorting screen by weight.

그러나, 이와 같이 구성된 종래의 건설폐기물의 이물질 선별장치는 연속적인 이물질 선별작업을 할 수 없는 문제점이 있었다. 즉, 이물질이 포함된 건설폐기물을 세척수조에 넣고 부상하는 이물질을 제거수차를 이용하여 퍼내서 제거한 다음 세척수조 바닥에 침전된 골재를 빼내서 분리하는 작업이 모두 완료된 뒤에, 새로운 건설폐기물을 세척수조에 다시 넣어야 하기 때문에 작업의 연속성이 없는 문제점이 있었다. 또한, 상기 이물질 선별장치는 골재가 세척수조 바닥에 쌓이면서 그 사이에 끼게 되는 이물질들은 세척수조 내에서 부상하지 않기 때문에 선별이 쉽지 않은 문제점이 있었다.However, the conventional foreign matter sorting device of the construction waste constituted as described above has a problem in that the continuous foreign matter sorting operation cannot be performed. In other words, put the construction waste containing foreign matters into the washing tank, remove the floating foreign matter by using the removal aberration, remove the aggregate settled on the bottom of the washing tank, and then remove the new construction waste into the washing tank. There was a problem of no continuity of work because it had to be put back. In addition, the foreign matter sorting device has a problem that is not easy to sort because the aggregates accumulated on the bottom of the washing tank is not injured in the washing tank.

본 발명은 상술한 문제점을 개선하기 위해 제안된 것으로, 그 목적은 건설폐기물의 재활용 처리 시스템 중 파쇄와 선별과정을 거친 골재가 경사지게 설치된 회전통 내로 투입되면 이송스크류를 통해 골재는 상방향으로 이송되어 배출되고 이물질은 물위로 부상하는 원리를 이용해 선별 추출되어 하방향으로 배출되는 건설폐기물의 이물질 선별장치를 제공하는 데 있다.The present invention has been proposed to improve the above-mentioned problems, the object of which is that the aggregate after the crushing and sorting process in the recycling process of construction waste is put into the rotary cylinder installed inclined, the aggregate is transferred upward through the transfer screw It is to provide a foreign matter sorting device of construction waste that is discharged and discharged in a downward direction by using the principle that the foreign matter is discharged and floated on the water.

본 발명의 다른 목적은 회전통 내에서 골재가 계속 뒤집히면서 이송을 하기 때문에 이물질이 골재 사이에 끼는 현상이 발생되지 않아 보다 확실하게 이물질을 선별 추출할 수 있는 건설폐기물의 이물질 선별장치를 제공하는 데 있다.Another object of the present invention is to provide a foreign matter sorting device of the construction waste that can be more reliably picked out foreign matters because the phenomenon is not caught between the aggregates because the aggregates are continuously inverted in the rotary barrel to transfer. There is.

본 발명의 또 다른 목적은 이물질을 걸러내기 위해 사용되는 물을 순환시켜 재활용할 수 있도록 한 건설폐기물의 이물질 선별장치를 제공하는 데 있다.Still another object of the present invention is to provide a foreign matter sorting device for construction waste that can be recycled by recycling water used to filter foreign matter.

이제, 이와 같이 구성된 본 발명에 따른 건설폐기물의 이물질 선별장치의 작동 및 작용을 설명하면 다음과 같다.Now, the operation and operation of the foreign matter screening device for construction waste according to the present invention configured as described above are as follows.

본 발명은 먼저 물공급호스(50)를 통해 회전통(10) 내로 물을 공급하여 물이 회전통(10)의 바닥에 채워지고 넘치는 물은 하부공(12)을 통해 배출되도록 한다. 물론, 경우에 따라서는 하부공(12)으로 배출되는 물을 물순환호스(53)를 통해 다시 물공급호스(50)로 안내하여 회전통(10)내로 순환되도록 한다. 회전통(10) 내에 물 공급 작업이 완료되면, 회전통구동수단을 통해 회전통(10)을 회전시키면서, 건설폐기물의 재활용 처리 시스템 중 파쇄와 선별과정을 거친 골재를 투입호퍼(40)로 투입하여 회전통(10) 내로 안내한다. 그러면, 골재는 회전통(10)의 이송스크류(30)를 따라 회전통(10) 내에서 상부공(11) 방향으로 이동하게 되고, 골재이송수차(60)의 수차판을 통해 퍼 올려지며, 골재이송수차(60)의 상부에서 낙하되는 골재는 배출덕트(65)를 통해 골재이송컨베이어(66)로 안내된다. 그리고 골재에 포함되어 있는 이물질은 골재가 이송될 때 골재와 분리되어 물위로 부상되며, 물의 흐름방향을 따라 하부공(12) 방향으로 흘러 내려가게 된다. 이 과정에서, 이물질이 회전통(10)의 원심력에 의해 함께 회전하면서 상방향으로 이동하려는 경향은 걸림바(81)에 걸려 제한되며, 필요에 따라서는 실린더(82)의 로드(82a)의 작동에 의해 길이바(80)가 길이방향으로 왕복 이동하면서 걸림바(81)를 흔들어 주기 때문에 이물질이 걸림바(81)에 걸리는 현상이 생기지 않게 된다. 다음으로, 물을 따라 흘러 내려간 이물질은 이물질제거수차(70)의 수차판을 통해 걸러져 하부공(12)으로 바로 배출되지 않게 되며, 이물질제거수차(70)에서 퍼 올려진 이물질은 수차의 상부에서 낙하될 때 배출슈트(75)를 통해 안내되어 이물질이송컨베이어(76)로 안내된다. 한편, 골재에 포함되어 혹시 골재이송수차(60)를 통해 이송되는 이물질은 분사노즐(55)에서 분사되는 물에 의해 다시 걸려져 회전통(10) 내로 안내되어 확실한 이물질 선별이 가능하게 된다. 이와 같이 본 발명은 투입호퍼(40)를 통해 골재를 투입하면 이물질과 순수 골재를 자동으로 선별하여, 이물질은 이물질제거수차(70)를 통해 하부공(12)으로 배출되고 순수 골재는 골재이송수차(60)를 통해 상부공(11)으로 배출된다.The present invention first supplies the water into the rotary tube 10 through the water supply hose 50 so that the water is filled in the bottom of the rotary tube 10 and the excess water is discharged through the lower hole (12). Of course, in some cases, the water discharged to the lower hole 12 is guided back to the water supply hose 50 through the water circulation hose 53 to be circulated into the rotary cylinder 10. When the water supply operation in the rotary cylinder 10 is completed, while rotating the rotary cylinder 10 through the rotary cylinder driving means, the aggregates subjected to the crushing and sorting process of the recycling treatment system of construction waste is introduced into the input hopper 40 To guide into the rotating cylinder (10). Then, the aggregate is moved in the direction of the upper hole 11 in the rotary cylinder 10 along the conveying screw 30 of the rotary cylinder 10, and is pumped up through the aberration plate of the aggregate transport aberration 60, aggregate Aggregate falling from the upper portion of the conveyance aberration 60 is guided to the aggregate conveyance conveyor 66 through the discharge duct (65). The foreign matter contained in the aggregate is separated from the aggregate when the aggregate is transported and floated on the water, and flows down to the lower hole 12 along the flow direction of the water. In this process, the tendency of the foreign matter to move upward while rotating together by the centrifugal force of the rotary cylinder 10 is limited to the locking bar 81, and if necessary, the operation of the rod 82a of the cylinder 82 As a result, the length bar 80 shakes the catching bar 81 while reciprocating in the longitudinal direction, thereby preventing the foreign matter from being caught by the catching bar 81. Next, the foreign matter flowing down the water is filtered through the aberration plate of the foreign matter removal aberration 70 is not discharged directly to the lower hole 12, foreign matters raised from the foreign matter removal aberration 70 in the upper portion of the aberration When falling, it is guided through the discharge chute 75 to the foreign matter conveyance conveyor (76). On the other hand, the foreign matter contained in the aggregate may be conveyed through the aggregate transport aberration (60) is caught again by the water sprayed from the injection nozzle 55 is guided into the rotary cylinder 10, it is possible to be sure foreign matter selection. As described above, when the aggregate is input through the input hopper 40, the foreign matter and pure aggregate are automatically selected, and the foreign matter is discharged to the lower hole 12 through the foreign matter removal aberration 70 and the pure aggregate is the aggregate transport aberration. Through the 60 is discharged to the upper hole (11).
