Description

재생골재 선별장치{Recycled aggregate sorting device}Recycled aggregate sorting device

본 발명은 메쉬크기에 따라 순차적으로 배열된 원형의 걸름망이 회전하면서 공급되는 재생골재를 크기별로 구분하여 선별하도록 하도록 한 것으로 특히 설치면적을 최소화 하면서도 최상의 선별효과를 얻을 수 있는 재생골재의 선별장치에 관한 것이다.The present invention is to sort and sort the recycled aggregate supplied by rotating the circular sieve nets arranged sequentially according to the mesh size by size, in particular to the sorting device of the recycled aggregate can obtain the best screening effect while minimizing the installation area It is about.

일반적으로 노후된 건물이나 교량 및 도로 등과 같은 건축 및 토목 구조물을 해체하게 되면 해체된 구조물은 엄청난 양의 건설폐기물로 남게 된다. 이러한 건설폐기물은 여타의 산업폐기물과 같이 환경을 해치는 또 다른 공해물로 작용하게 되므로 이의 처리에 많은 애로점이 있었다.In general, when dismantling architectural and civil structures such as aging buildings, bridges and roads, the dismantled structure remains a huge amount of construction waste. This construction waste, like other industrial waste, acts as another pollution that harms the environment, and thus has had many difficulties in its disposal.

건설폐기물은 주로 매립에 의해 처리하게 되는데, 건설폐기물에는 각종 쓰레기나 썩지 않는 폐자재도 포함되어 있기 때문에 이는 토양을 오염시키는 원인으로 작용하게 됨은 물론이고 재활용될 수 있는 자원을 낭비하게 되는 겪이 되게 된다.Construction waste is mainly treated by landfill. Since construction waste contains various kinds of garbage and non-corrosive waste, it not only contributes to soil pollution but also wastes resources that can be recycled. .

이 때문에 자원의 절약과 재활용 촉진에 관한 법률이 제정되기에 이르렀고, 그로인하여 단순 소각처리나 매립처리되던 방식에서 폐기물의 수거에서 재생까지의 과정을 하나의 시스템으로 처리하여 재활용하는 방식으로 바뀌게 되었다.This led to the enactment of legislation on the conservation and recycling of resources, thereby shifting the process from simple incineration or landfill to the recycling of waste from one collection to recycling.

건설폐기물을 재생골재로 재활용하는 시스템은 수거된 건설폐기물을 죠크러셔를 통해 1차 파쇄하는 공정과, 파쇄된 건설폐기물에 혼재되어 있는 금속등을 제거하는 1차선별공정과, 쓰레기나 목재 및 협잡물 및 골재표면에 부착된 흙분과 같은 이물질을 제거하는 2차선별공정과, 선별된 건설폐기물을 콘크러셔나 볼크러셔를 통해 파쇄하는 공정과, 최종적으로 파쇄된 파쇄물을 그 크기별로 분류하는 공정으로 크게 구성된다.The system for recycling construction waste into recycled aggregates includes the primary crushing process of the collected construction waste through the jaw crusher, the primary screening process to remove metals mixed in the crushed construction wastes, and the waste, wood, and junk products. And a second sorting process for removing foreign substances such as soil powder attached to the aggregate surface, a process of crushing the selected construction waste through a crusher or a ball crusher, and finally classifying the crushed crushed material by its size. It is composed.

그런데 재생골재 생산 시스템에서 최종적으로 파쇄물을 크기별로 나누는 선별장치들의 크기가 매우 크고 그로인한 대형 설치면적이 소요되는 문제점이 있었다. 즉, 골재로 사용되는 재생골재의 크기를 200mm, 40mm, 25mm, 9mm 정도의 직경을 갖는 것들로 구분하고자 한다면, 그 골재의 크기마다 선별스크린을 설치해야 하고, 또 각 스크린을 잇는 컨베이어를 장치해야 하기 때문에 선별장치의 부피가 매우 대형화되고 그에 따른 설치면적도 많이 필요하게 되는 문제점이 있었다.However, in the recycled aggregate production system, there is a problem in that the size of the sorting device that finally divides the shreds by size is very large and thus requires a large installation area. In other words, if the size of recycled aggregate used as aggregate is to be divided into those having diameters of 200mm, 40mm, 25mm, 9mm, the sorting screen should be installed for each aggregate size, and the conveyor connecting each screen should be installed. Since there is a problem that the volume of the sorting device is very large and the installation area is also required accordingly.

또한 종래의 선별장치는 대부분 외부로 노출된 구조이기 때문에 재생골재의 선별시 많은 먼지나 분진을 발생시켜 작업장의 주변과 작업장의 환경을 오염시키게 되고 그로인한 민원을 유발하는 폐단이 있었다.In addition, since the conventional sorting device is mostly exposed to the outside, when the recycled aggregates are screened, a lot of dust or dust is generated, which contaminates the surroundings of the workplace and the environment of the workplace, thereby causing a complaint.

본 발명은, 상기와 같은 종래의 선별장치의 단점을 해소하기 위해 창안된 것으로, 그 목적은 최소의 부피와 설치면적으로 고효율 재생골재 선별 처리능력을 가질 수 있는 재생골재 선별장치를 제공하는데 있다.The present invention has been made to solve the disadvantages of the conventional sorting device as described above, the object is to provide a recycled aggregate sorting device that can have a high efficiency recycled aggregate sorting capacity with a minimum volume and installation area.

또한 본 발명은 선별과정시 먼지의 발생이 없도록 하는 재생골재 선별장치를 제공하는데 있다.In another aspect, the present invention to provide a recycled aggregate sorting device to prevent the generation of dust during the sorting process.

도시된 바와 같이 본 발명의 선별장치는, 크게 수직축(10)에 다층으로 배열되어 구동장치에 의해 회전되는 걸름망(20a∼20e)과, 상기 걸름망(20a∼20e)의 둘레에 씌워져 고정설치되고 상부에 재생 골재 투입부(38)를 갖고 상기 걸름망(20a∼20e)에 의해 이루어지는 각층의 측부에 걸러진 골재를 배출하는 골재배출슈트(32a∼32e)를 포함하는 원통형 케이스(30)로 구성되어 있다.As shown in the drawing, the sorting device of the present invention is largely arranged in a multi-layer on the vertical axis 10 and is secured by being fitted around the strainer 20a to 20e and the strainer 20a to 20e which are rotated by the driving device. And a cylindrical case 30 including aggregate discharge chutes 32a to 32e for discharging aggregate aggregated to the side portions of each layer formed by the strainer 20a to 20e.

상기 수직축(10)상에 다층으로 설치되는 걸름망(20a∼20e)은 원형이며, 상부는 메쉬가 크고 하부로 갈 수록 작아지는 순서로 배열된다. 이때 최하부 걸름망(20e)은 망이 아닌 원판이 설치되어 미분의 골재가 빠져나가지 않도록 되어 있으므로 최종적으로 미분을 분리할 수 있도록 구성되어 있다. 상기 수직축(10)은 상하 축받이(22,22')에 회전가능하게 축착되는데, 하부의 축받이(22')와는 베어링에 의해 회전가능하게 설치된 스플라인기어(23)로 연결되어 회전중에도 승하강 유동이 가능하도록 되어 있고, 하부 축받이(22')와 수직축(10) 하단 사이에 진동스프링(24)이 설치되어 있고, 수직축(10)의 상부에 별도의 진동장치(25)가 연결되어 있어 걸름망(20a∼20e)의 회전중에 진동을 가할 수 있도록 되어 있다. 이때진동장치(25)와 진동스프링(24)과 같은 구성은 필요에 따라 제거하여도 무방하다. 또 수직축(10)의 상단부에는 후에 상세히 설명될 원통형 케이스(30)의 상부에 설치되는 구동모터(26)가 동력전달장치로 연결되어 회전된다. 필요에 따라서는 구동모터(26)가 수직축(10)의 하부에 연결·설치될 수도 있다.The filtering nets 20a to 20e installed in multiple layers on the vertical axis 10 are circular, and the upper part is arranged in order of increasing size of the mesh and decreasing toward the lower part. At this time, the lower strainer (20e) is configured to be able to separate the fine powder because the disc is not installed so that the aggregate of fine powder is not escaped. The vertical shaft 10 is rotatably fixed to the upper and lower bearings 22 and 22 ', and the lower bearing 22' is connected to a spline gear 23 rotatably installed by a bearing so that the lowering and lowering flow is possible even during rotation. It is possible to, a vibration spring 24 is installed between the lower bearing 22 'and the lower end of the vertical shaft 10, and a separate vibrator 25 is connected to the upper portion of the vertical shaft 10, the strainer 20a Vibration can be applied during the rotation of -20e). At this time, the configuration such as the vibration device 25 and the vibration spring 24 may be removed if necessary. In addition, the upper end of the vertical shaft 10, the drive motor 26 is installed in the upper portion of the cylindrical case 30 to be described later in detail is connected to the power transmission device is rotated. If necessary, the drive motor 26 may be connected to and installed under the vertical shaft 10.

이러한 걸름망(20a∼20e)의 외부에 설치되는 원통의 케이스(30)는 하부의 베이스프레임(60)상에 견고하게 설치되며, 각 걸름망(20a∼20e)에 의해 구성되는 각 공간의 측부에 골재배출슈트(32a∼32e)들이 각각 설치된다. 그리고 각 골재배출슈트(32a∼32e)들은 크기별로 선별된 골재들을 이송하는 컨베이어와 연결되며, 최상단에 위치한 골재배출슈트(32a∼32e)와 연결되는 컨베이어는 골재를 파쇄하는 크러셔로 피드백 되도록 되어 있다. 이는 최상단의 걸름망(20a∼20e)을 통과하지 못한 골재는 규격 이상의 크기를 가지고 있는 것이기 때문에 규격의 골재의 크기이하로 파쇄시키기 위함이다. 그리고 케이스의 상부 또는 하부에 집진기(12)가 설치되어 내부에서 발생된 먼지나 분진을 제거할 수 있도록 되어 있다.The cylindrical case 30 installed outside of the strainer 20a to 20e is firmly installed on the base frame 60 at the bottom thereof, and aggregates on the side of each space constituted by the strainer 20a to 20e. Discharge chutes 32a to 32e are provided respectively. And each aggregate discharge chute (32a ~ 32e) is connected to the conveyor for transporting the aggregates sorted by size, the conveyor connected to the aggregate discharge chute (32a ~ 32e) located at the top is to be fed back to the crusher crushing aggregate. . This is because the aggregate that does not pass through the uppermost strainer (20a to 20e) has a size larger than the specification, so that the aggregate to be shredded below the size of the aggregate of the specification. And the dust collector 12 is installed on the upper or lower portion of the case to remove the dust or dust generated inside.

또한 상기 각 걸름망(20a∼20e) 하부 공간부에는 하부에 위치한 걸름망(20a∼20e)의 중앙부를 향하여 경사지게 설치된 안내판(34)이 구비되며 이 안내판(34)은 케이스(30) 내벽면에 고정설치된다. 즉, 걸름망(20a∼20e)을 통과한 골재를 하부의 걸름망(20a∼20e) 중앙부로 안내하여 하부 걸름망(20a∼20e)에 머무를 수 있는 시간을 더 갖도록 하기 위한 것이다.In addition, the lower space portion of each strainer (20a to 20e) is provided with a guide plate 34 inclined toward the center of the strainer (20a to 20e) located at the bottom, the guide plate 34 is fixed to the inner wall surface of the case (30) do. That is, to guide the aggregate passed through the strainer (20a to 20e) to the center of the lower strainer (20a to 20e) to have a more time to stay in the lower strainer (20a to 20e).

또한 상기 걸름망(20a∼20e)의 상부에는 상기 수직축(10)에서 상기 회전방향의 골재배출슈트(32a∼32e)의 측단부로 연결되는 골재선별가이드(36)가 장치되어있다. 이 골재선별가이드(36)는 외측단이 골재배출슈트(32a∼32e)의 측단, 즉 회전방향의 골재배출슈트(32a∼32e)에 고정설치되고 내측단은 수직축(10)에 유설되어 지지되며 그 형상은 도 2에서와 같이 걸름망(20a∼20e)의 회전방향으로 나선을 이루는 구조로 되어 있다.In addition, an aggregate selection guide 36 connected to the side ends of the aggregate discharge chute 32a to 32e in the rotational direction is provided at the upper portion of the strainer 20a to 20e. The aggregate selection guide 36 is fixed to the side end of the aggregate discharge chute (32a to 32e), that is, the aggregate discharge chute (32a to 32e) in the rotational direction and the inner end is supported on the vertical axis (10) As shown in Fig. 2, the shape has a structure that forms a spiral in the rotational direction of the strainer 20a to 20e.

이러한 구성으로 이루어진 본 발명의 선별장치의 작용을 살펴본다.It looks at the operation of the sorting device of the present invention made of such a configuration.

구동모터(26)에 의해 수직축(10)이 회전하여 각 층의 걸름망(20a∼20e)이 회전되고 진동장치(25)가 작동되는 상태에서 생산된 재생골재가 투입부(38)를 통해 투입되면 중앙부에서부터 골재배출슈트(32a∼32e)쪽으로 연결된 골재선별가이드(36)에 의해 골고루 펴지면서 골재배출슈트(32a∼32e)로 안내된다. 그 과정에서 걸름망(20a∼20e)의 메쉬보다 작은 골재는 하부로 빠져나가게 되고 메쉬보다 큰 골재는 골재선별가이드(36)에 의해 골재배출슈트(32a∼32e)로 배출된다. 특히 진동장치(25)의 작동에 의해 각 망이 진동하게 되면 그 위에 놓여진 재생골재들이 극심하게 유동하여 자리이동하게 되므로 각 재생골재들은 걸름망(20a∼20e)의 메쉬를 통과할 기회를 더욱더 많이 가질 수 있으므로 선별효과가 증가하게 된다. 물론 진동장치(25)의 작동 없이도 선별작동은 이루어진다.When the vertical shaft 10 is rotated by the drive motor 26, the recycled aggregate produced while the strainer 20a to 20e of each layer is rotated and the vibrator 25 is operated is introduced through the input unit 38. Guided to the aggregate discharge chute (32a to 32e) while spreading evenly by the aggregate selection guide 36 connected from the center toward the aggregate discharge chute (32a to 32e). In the process, the aggregate smaller than the mesh of the strainer 20a to 20e exits to the bottom and the aggregate larger than the mesh is discharged to the aggregate discharge chute 32a to 32e by the aggregate selection guide 36. In particular, when each network vibrates by the operation of the vibrator 25, the recycled aggregates placed thereon are moved in a state of extreme flow, and thus each recycled aggregate has more opportunities to pass through the mesh of the strainer 20a to 20e. As a result, the screening effect is increased. Of course, the screening operation is made without the operation of the vibration device (25).

한편, 최상측에 배열된 첫번째 걸름망(20a)을 통과하지 못한 재생골재는 규격 이상의 크기이므로 연결된 컨베이어를 통해 다시 크러셔로 리턴시켜 파쇄시킨 후 다시 선별장치로 선별하도록 한다. 이와는 반대로 최상부에 위치한 걸름망(20a)을 통과한 재생골재는 하부로 낙하되면서 안내판(34)에 의해 하부에 위치한 두 번째 걸름망(20b)의 중앙부로 공급된다. 이 두 번째 걸름망(20b)에서 동일한 작동에의해 걸러진 재생골재는 골재배출슈트(32a∼32e)를 통해 그 규격의 골재를 적재하는 위치로 이송되며, 두번째 걸름망(20b)을 통과한 재생골재는 그 하부에 위치한 세번째, 네번째, 다섯번째 걸름망(20c∼20e)으로 떨어져 상술한 동일한 작동을 반복하여 크기별로 구분 적재된다.On the other hand, the recycled aggregate that does not pass through the first strainer (20a) arranged on the top side is larger than the standard size is returned to the crusher through a connected conveyor to be crushed and sorted again by the sorting device. On the contrary, the recycled aggregate that has passed through the strainer 20a positioned at the top thereof is dropped to the lower portion and is supplied to the center portion of the second strainer 20b positioned below by the guide plate 34. The recycled aggregate filtered by the same operation in this second strainer 20b is transferred to the position of loading the aggregate of the specification through the aggregate discharge chute 32a to 32e, and the recycled aggregate passed through the second strainer 20b is The third, fourth, and fifth filter nets 20c to 20e located at the bottom are separated and stacked by size by repeating the same operation described above.

도 3은 본 발명의 재생골재 선별장치에 걸름망 구조를 가변시킨 종단면도로서, 도시된 바와 같이 본 발명의 걸름망(50a∼50e)이 외측방향으로 완만한 하향 경사각을 갖는 원추형으로 구성되어 있다. 이러한 걸름망(50a∼50e) 형상은 자중에 의해 재생골재가 용이하게 바깥쪽으로 이동할 수 있도록 하기 위한 것이며, 그 경사도 및 걸름망(50a∼50e)의 회전속도에 따라 골재선별가이드(36)의 기능 없이도 재생골재의 이동이 가능하다.Figure 3 is a longitudinal cross-sectional view of the strain screen structure is changed in the recycled aggregate sorting apparatus of the present invention, as shown in the strain screen (50a to 50e) is configured in a conical shape having a gentle downward slope in the outward direction. The shape of the mesh 50a to 50e is to allow the recycled aggregate to move outward easily by its own weight, and is regenerated without the function of the aggregate selection guide 36 according to its inclination and the rotational speed of the mesh 50a to 50e.

도 4는 본 발명의 재생골재 선별장치에 보조걸름망 구조를 부가한 종단면도로서, 도시된 바와 같이 각 골재배출슈트(62)의 하부에는 연결된 층의 걸름망(20a∼20e)(50a∼50e)과 동일한 메쉬의 크기를 갖는 보조걸름망(64)이 설치되어 있고, 그 하부는 하층의 안내판(66) 상단이 연장되어 골재배출슈트(62)와 하부공간을 연결하고 있다.4 is a longitudinal cross-sectional view of the auxiliary aggregate screen structure added to the recycled aggregate sorting apparatus of the present invention, as shown in the lower portion of each aggregate discharge chute 62, the mesh screen 20a to 20e (50a to 50e) of the connected layer and An auxiliary strainer 64 having the same mesh size is provided, and the lower portion of the lower guide plate 66 extends to connect the aggregate discharge chute 62 to the lower space.

이 구성은 각 걸름망(20a∼20e)(50a∼50e)에 의해 걸러져 골재배출슈트(62)로 배출되는 재생골재 중 크기가 작음에도 불구하고 미처 걸름망(20a∼20e)(50a∼50e)을 통과하지 못한 재생골재가 포함될 수 있다. 이와 같이 배출되는 작은 재생골재들이 골재배출슈트(62)를 통과하면서 그 바닥에 설치된 보조걸름망(64)에 의해 재차 걸러지게 될 기회를 한 번더 가지게 되며,보조걸름망(64)을 통과한 재생골재들은 보조걸름망(64)의 하부로 연장된 안내판(66)에 의해 하부에 위치한 걸름망(20a∼20e)(50a∼50e)으로 공급되므로 재생골재 선별공정의 신뢰도를 높일 수 있게 된다.This configuration passes through the strainer 20a-20e (50a-50e) despite the small size of the recycled aggregate that is filtered by the strainer 20a-20e (50a-50e) and discharged to the aggregate discharge chute 62. May not contain recycled aggregates. The small recycled aggregates discharged as described above have an opportunity to be filtered again by the auxiliary strainer 64 installed on the bottom while passing through the aggregate discharge chute 62, and the recycled aggregates passed through the secondary strainer 64 are Since the guide plate 66 extended to the lower portion of the auxiliary strainer 64 is supplied to the strainer 20a to 20e (50a to 50e) located at the bottom, it is possible to increase the reliability of the recycled aggregate sorting process.

이러한 구성으로 되어있는 본 발명의 선별장치는 그 스크린이 상하 적층된 구조를 가지고 있고, 또 가 스크린이 회전과 함께 진동하여 재생골재의 선별효과를 배가시키도록 되어 있으므로 장치의 부피와 설치면적으로 최소화 할 수 있으면서 고효율 재생골재 선별 처리능력을 가질 수 있는 장점이 있다.The sorting apparatus of the present invention having such a configuration has a structure in which the screens are stacked up and down, and the screen is vibrated with rotation to double the sorting effect of the recycled aggregate, thereby minimizing the volume and installation area of the apparatus. There is an advantage that can have a high efficiency recycled aggregate sorting treatment.

특히 재생골재의 선별작동이 원통의 케이스 내부에서 모두 이루어지기 때문에 먼지나 분진이 발생되지 않음은 물론이고 특히 집진기에 의해 내부에서 발생된 먼지나 미분이 제거되기 때문에 작업장 주변은 물론이고 작업장 내에서도 쾌적한 환경을 가질 수 있는 장점이 있다.In particular, since the sorting operation of the recycled aggregate is performed inside the cylinder case, dust and dust are not generated, and in particular, dust and fine particles generated inside by the dust collector are removed, thereby making it a pleasant environment not only in the workplace but also in the workplace. There is an advantage to have.
