본 발명은 재생골재의 표면박리 및 입형개선 장치에 관한 것으로, 건설폐기물의 중간처리공정을 통해 생산되는 재생골재의 품질을 보다 향상시키기 위한 일환으로, 재생골재의 표면에 붙어 있는 모르타르를 박리시킴과 동시에 입형을 개선하여 양질의 재생골재를 획득할 수 있는 재생골재의 표면박리 및 입형개선 장치에 관한 것이다.The present invention relates to a surface peeling and granular improvement device of recycled aggregates, and in order to further improve the quality of recycled aggregates produced through the intermediate treatment process of construction wastes, peeling mortar adhered to the surface of recycled aggregates. At the same time it relates to the surface peeling and granular improvement device of the recycled aggregate that can obtain a good recycled aggregate by improving the shape.

친환경적 측면 및 자원의 재활용 측면에서, 건설 및 건축 구조물의 해체시에 발생하는 폐기물은 매립되지 않고 소정의 장소로 수집된 후 중간처리공정을 통해 양질의 자원으로 생산되고 있다. 특히, 건설폐기물의 재생골재는 도시와 지방 건축물의 재건축의 활성화에 따른 다량의 구조물 해체에 의해 그 활용도가 크게 증가되고 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 are produced as quality resources through an intermediate treatment process. In particular, the recycled aggregate of construction waste has been greatly increased its utilization by dismantling a large number of structures according to the activation of reconstruction of urban and local buildings.

상기 건설폐기물의 중간처리공정을 대략적으로 살펴보면, 수집된 건설폐기물은 파쇄기에 의해 1차 파쇄된 후 전자석 자선기에 의해 고철이 분리 배출되며, 그 후 송풍과 회전으로 토사 및 이물질이 분리 배출된 후 VIB 스크린에 의해 폐목재류 및 각종 쓰레기가 분리배출된 후 고압의 물분사에 의해 기타의 이물질이 제거된다. 그 후 2차, 선택적으로 제3차 파쇄기에 의해 제2차, 선택적으로 제3차 파쇄되어 재생골재로서 입형이 마무리 되며, 선별기에 의해 다양한 크기의 재생골재가 획득되게 된다. Looking at the intermediate treatment process of the construction waste, the collected construction waste is first crushed by the crusher, and then scrap metal is discharged and separated by an electromagnet charity, after which the soil and debris is separated and discharged by blowing and rotating VIB After the waste wood and various wastes are separated and discharged by the screen, other foreign substances are removed by high pressure water spraying. Thereafter, secondary and optionally tertiary crushers are crushed to secondary and optionally tertiary crushing to finish the granules as recycled aggregates, and recycled aggregates of various sizes are obtained by the sorter.

하지만, 이와 같은 공정을 통해 획득된 재생골재라도 골재 표면에 부착된 시멘트 모르타르등으로 인해 천연골재에 비해 골재의 입형상태가 양호하지 못해 외관불량은 물론이고 현장 적용시 골재 표면과 모르타르와의 부착력이 감소되며, 흡수율이 높아 재생골재의 강도가 떨어진다는 문제점이 있다. However, even the recycled aggregates obtained through such a process have poor granularity compared to natural aggregates due to cement mortar attached to the aggregate surface, resulting in poor appearance and adhesion between the aggregate surface and the mortar during field application. It is reduced, there is a problem that the absorption rate is high and the strength of the recycled aggregates falls.

이러한 이유로 인해, 재생골재는 일반적으로 2종 골재로서 콘크리트 블록, 도로구조물 기초, 측구, 집수받이기초, 중력식 옹벽, 중력식 교대등에 콘트리트와 배합 시공되며, 또는 3종 골재로서 강도가 크게 요구되지 않은 막콘크리트, 채움재 콘크리트, 건축물의 비구조체 콘크리트등에 배합되어 활용될 뿐, 교량 하부공, 융벽, 터널 라이닝공에 배합되는 1종 골제에는 활용되지 못하고 있는 실정이다.For this reason, recycled aggregates are generally two kinds of aggregates, concrete blocks, road structures foundations, sideways, catch basins, gravity retaining walls, gravity shifts, etc. It is mixed with concrete, filler concrete, non-structural concrete of buildings, etc., but it is not used for one type of aggregate compounded in bridge lower holes, molten walls and tunnel lining.

이에, 건설폐기물의 중간처리공정을 통해 생산되는 재생골재를 타격하여 모르타르를 제거하고 입형을 개선하여 양질의 재생골재를 획득하기 위한 타격식 박리기가 국내 실용신안등록 제418198호에 개시되어 있는 데, 상기 타격식 박리기는 도1에 도시된 바와 같이 직립하여 있는 하우징내에 타격봉이 형성된 회전축을 착설함으로써 하우징내로 투입되는 재생골재를 타격봉이 타격하게 한 구성을 소개하고 있다. Accordingly, a blow type extruder is disclosed in Korean Utility Model Registration No. 414198 for hitting recycled aggregate produced through an intermediate treatment process of construction waste to remove mortar and improve the shape to obtain high quality recycled aggregate. The blow type extruder introduces a configuration in which the striking rod strikes the recycled aggregate introduced into the housing by installing a rotating shaft in which the striking rod is formed in the upright housing as shown in FIG.

하지만, 상기 타격식 박리기는 하우징이 직립하여 설치되어 있기 때문에 재생골재가 중력에 의해 급속하게 박리기를 통과하여 박리 및 입형개선이 제대로 이 루어질 수 없다는 문제가 있으며, 이를 해결하기 위해 하우징의 높이를 높게 하면 장지가 비대해져서 설치비용이 증가하고 하우징내에 재생골재를 투입하는 것이 어려워지는 단점이 있다. 또한, 타격봉의 직경이 일률적이어서 박리를 위한 타격과 입형개선을 위한 타격이 선택적으로 이루어질 수 없다는 단점이 있다. 또한, 박리된 이물질이나 석분은 배출가이드부재를 통과하여 하우징하단에 쌓이게 되는 데, 상기 박리기는 쌓인 이물질이나 석분을 트레이를 통해 인부가 외부로 배출해야 하므로, 이물질이나 석분 배출작업이 불편하고 번거로운 문제점이 있었다.However, since the blow-type peeler has a housing installed upright, there is a problem in that the recycled aggregate passes through the peeler rapidly by gravity and peeling and improvement of the shape can not be made properly. If it is high, there is a disadvantage in that the installation cost increases due to enlargement of the jangji and it is difficult to put recycled aggregate into the housing. In addition, since the diameter of the striking rod is uniform, there is a disadvantage that the striking for peeling and the striking for improving the shape cannot be selectively made. In addition, the separated foreign matter or stone powder passes through the discharge guide member to be accumulated at the bottom of the housing, the peeling machine has to discharge the accumulated foreign matter or stone powder to the outside through the tray, the foreign matter or stone powder discharge operation is inconvenient and cumbersome problem There was this.

본 발명은 상기 문제점을 해결하기 위해 안출된 것으로, 본 발명의 목적은 투입된 재생골재가 저속으로 박리기를 통과하게 하여 박리작업과 입형개선작업이 충분히 진행될 수 있는 재생골재의 표면박리 및 입형개선 장치를 제공하는 것이다. The present invention has been made to solve the above problems, an object of the present invention is to put the recycled aggregate is introduced through the peeler at a low speed peeling and surface improvement of the recycled aggregate can be carried out to improve the shape of the aggregate To provide.

상술한 본 발명의 목적은 첨부된 도면을 참조하여 후술되는 본 발명의 바람직한 실시예로부터 더욱 명확해질 것이다.The object of the present invention described above will become more apparent from the preferred embodiment of the present invention described below with reference to the accompanying drawings.

이하, 첨부된 도면을 참고하여 본 발명에 따른 재생골재의 표면박리 및 입형개선 장치를 보다 상세하게 설명한다. 첨부된 도2는 본 발명에 따른 재생골재의 표면박리 및 입형개선 장치의 외형사시도이며, 도3은 도2의 A-A 단면도이며, 도4는 도2의 B-B 단면도이다.Hereinafter, with reference to the accompanying drawings will be described in more detail the surface peeling and granular improvement device of the recycled aggregate according to the present invention. 2 is an external perspective view of the surface peeling and granular improvement apparatus of the recycled aggregate according to the present invention, FIG. 3 is a sectional view taken along line A-A of FIG. 2, and FIG. 4 is a sectional view taken along line B-B of FIG.

상기 도면을 참고하면, 본 발명에 따른 재생골재의 표면박리 및 입형개선 장 치는 회전망체(10) 및 타격체(20)를 포함한다.Referring to the drawings, the surface peeling and granular improvement device of the recycled aggregate according to the present invention includes a rotating mesh 10 and the striking body 20.

상기 회전망체(10)는 미도시된 구동수단에 의해 회전되며 재생골재에서 박리된 모르타르와 같은 이물질이 이송과정에서 외부로 배출되도록 표면은 메쉬형상으로 이루어진다. 또한, 상기 회전망체(10)의 전방에는 재생골재가 투입되도록 투입공(11)이 형성되고 후방에는 재생골재가 배출되도록 배출공(12)이 형성된다. 즉, 회전망체의 양단은 개구되어 있다. The rotating mesh 10 is rotated by a driving means (not shown) and the surface is formed in a mesh shape so that foreign matters such as mortar peeled from the recycled aggregate are discharged to the outside during the transfer process. In addition, in the front of the rotating mesh 10, the input hole 11 is formed so that the recycled aggregate is input, and the discharge hole 12 is formed at the rear to discharge the recycled aggregate. That is, both ends of the rotating mesh are open.

또한, 상기 회전망체는 투입공(11)이 형성된 전방은 높고 배출공(22)이 형성된 후방은 낮게 경사배치되는 데, 이 경사각은 박리량과 입형개선정도에 따라 다양하게 증감할 수 있다. 즉, 많은 모르타르가 부착된 재생골재나 입형불량이 심한 재생골재의 경우에는 경사도를 완만하게 하여 서서히 회전망체내에서 이송하도록 할 수 있을 것이다. In addition, the rotating mesh is inclined arrangement is low in the front is formed in the injection hole 11 and the rear is formed in the discharge hole 22, this inclination angle can be increased or decreased in accordance with the peeling amount and the degree of improvement of the shape. In other words, in the case of recycled aggregates with a large number of mortars or regenerated aggregates with poor granularity, the slope may be smoothed and gradually transported in the rotating mesh.

또한, 상기 회전망체의 내주면에는 안내판(13)이 등간격으로 중심방향을 향해 돌출되도록 착설되는 데, 이는 회전망체(10)내로 투입된 재생골재가 상기 안내판(13)에 적재된 후 회전망체의 회전방향으로 회전하다가 정상 부근에서 떨어져 후술한 타격판(20)의 타격봉(21)에 의해 타격될 수 있도록 하기 위함이다. 여기서, 바람직하게 상기 안내판(13)은 안내판에 적재되어 회전하는 골재가 중간에서 떨어지지 않도록 도4에 도시된 바와 같이 회전망체(10)의 회전방향측으로 경사지게 형성된 것이 바람직하다.In addition, the inner circumferential surface of the rotating mesh is installed so that the guide plate 13 protrudes toward the center direction at equal intervals, which is recycled aggregate introduced into the rotating mesh 10 is loaded on the guide plate 13 and the rotating mesh This is to rotate in the direction of rotation of the sieve so that it can be hit by the striking rod 21 of the striking plate 20 to be described later. Here, the guide plate 13 is preferably formed to be inclined toward the rotation direction side of the rotating mesh 10 as shown in Figure 4 so that the aggregate loaded on the guide plate does not fall in the middle.

상기 타격체(20)는 그 외주연에 걸쳐 형성된 타격봉(21)으로 회전망체에서 회전이송되는 골재를 타격하여 표면박리작업과 입형개선작업을 수행하는 것으로, 상기 회전망체(10)의 내부 중앙에 상기 회전망체(10)의 길이방향을 따라 설치되며, 미도시된 구동수단에 의해 상기 회전망체의 회전방향과 역방향으로 회전된다. 즉, 도시하지는 않았지만 상기 회전망체(10)의 일측은 구동수단의 회전축과 결합되어 회전되고, 타측은 베어링에 지지되어 회전가능하게 고정된다.The striking body 20 is to hit the aggregate rotated from the rotating mesh with the striking rod 21 formed over the outer periphery to perform the surface peeling work and the shape improvement work, of the rotating mesh 10 It is installed along the longitudinal direction of the rotating mesh 10 in the inner center, and is rotated in the opposite direction to the rotating direction of the rotating mesh by a driving means not shown. That is, although not shown, one side of the rotating mesh 10 is coupled to the rotating shaft of the driving means is rotated, the other side is supported by the bearing is rotatably fixed.

여기서, 상기 회전망체(10)는 투입된 골재를 안내판(21)에 적재시켜 서서히 회전상승시켜 자연낙하시킬 수 있을 정도로 저속회전하는 것이 바람직하며, 상기 타격체(20)는 골재를 직접적으로 타격하여 표면박리 및 입형을 개선해야 하므로 골재의 표면박리와 입형개선에 필요한 충격량을 제공할 수 있도록 고속회전하는 것이 바람직하다. 이에 예시적이지만 상기 회전망체(10)의 회전속도는 10rpm 내지 30rpm인 것이 바람직하며, 상기 타격체(20)의 회전속도는 500rpm 내지 800rpm인 것이 바람직하다. Here, the rotating mesh 10 is loaded to the aggregate loaded on the guide plate 21 is rotated slowly so that it can be rotated slowly to fall naturally, the striking body 20 hits the aggregate directly Since it is necessary to improve surface peeling and shape, it is desirable to rotate at a high speed so as to provide an amount of impact necessary for surface peeling and shape improvement of the aggregate. Exemplary, but the rotational speed of the rotating mesh 10 is preferably 10rpm to 30rpm, the rotational speed of the striking body 20 is preferably 500rpm to 800rpm.

한편, 상기 타격봉(21)은 투영하여 보았을 때 겹치지 않도록 지그재그로 형성되는 것이 바람직하며, 또한 도5에 도시된 바와 같이 박리용 타격봉(21-1)과 입형개선용 타격봉(21-2)으로 분리구성되는 것이 바람직하다. 즉, 상기 박리용 타격 봉(21-1)은 타격체(20)의 상단에서 대략 2/3 부분까지 형성된 타격봉으로 골재를 초기에 타격하여 골재에 견고하게 부착된 시멘트 모르타르를 제거해야 하므로 타격에 의한 충격량을 증가시키기 위해 직경이 후술할 입형개선용 타격봉 보다 상대적으로 큰 것이 바람직하다. On the other hand, the striking rod 21 is preferably formed in a zigzag so as not to overlap when viewed in projection, and also as shown in Figure 5 peeling striking rod (21-1) and a blow-up striking rod (21-2) It is preferred to be separated into). That is, the peeling striking rod 21-1 is a striking rod formed up to approximately 2/3 part from the top of the striking body 20 to hit the aggregate initially to remove the cement mortar firmly attached to the aggregate In order to increase the amount of impact by, it is preferable that the diameter is relatively larger than that of the impact improvement rods to be described later.

또한, 상기 입형개선용 타격봉(21-2)은 타격체 하단에서 대략 1/3 부분까지 형성된 타격봉으로, 전술한 박리용 타격봉(21-1)에 의해 타격되어 모르타르가 이탈된 골재의 각진 모서리을 타격하여 입형을 개선하기 위한 것이다. 즉, 상기 입형개선용 타격봉(21-1)은 미박리된 모르타르도 박리시키겠지만, 주요목적은 각진 모서리를 타격하여 입형을 개선하기 위한 것이라는 점에서 박리용 타격봉 보다 충격량이 크지 않아도 되므로, 그 직경은 박리용 타격봉의 직경 보다 작은 것이 바람직하다. In addition, the upright striking rod (21-2) is a striking rod formed up to approximately 1/3 of the bottom of the striking body, the impact of the above-described aggregate of the mortar is separated by the blow striking rod (21-1) To improve the shape by hitting angled corners. In other words, the riser blow bar 21-1 may peel off unpeeled mortar, but since the main purpose is to improve the shape by hitting angled corners, the impact amount does not have to be greater than that of the peeling blow bar. It is preferable that the diameter is smaller than the diameter of the peeling striking rod.

이에 예시적이지만 박리용 타격봉(21-1)의 직경은 3cm 내지 5cm 정도인 것이 바람직하며, 상기 입형개선용 타격봉(21-2)의 직경은 1cm 내지 2cm 정도인 것이 바람직하다. Although exemplary, the diameter of the peeling bar 21-1 is preferably about 3cm to about 5cm, and the diameter of the uplifting bar 21-2 is preferably about 1cm to about 2cm.

이와 같이 구성된 본 발명에 따른 재생골재의 표면박리 및 입형개선 장치에 대해 작용에 대해 설명한다.It will be described the operation of the surface peeling and granular improvement device of the recycled aggregate according to the present invention configured as described above.

먼저, 도6(a)에 도시된 바와 같이 미도시된 구동모터에 의해 회전되고 있는 회전망체(10)의 투입구(11)측으로 재생골재가 투입되면, 투입된 재생골재는 회전망체의 안내판(13)에 적재된 상태에서 안내판(13)과 함께 회전상승된다. 이 때, 안내판(13)은 바람직하게 회전망체(10)의 회전방향측으로 경사져 있기 때문에 회전망체(10)의 회전 정상점 부근까지 떨어지지 않고 상승할 수 있게 된다. 또한, 투입된 재생골재는 투입구(11)측에서 배출구(12)측으로 경사지게 설치된 회전망체(10)내에서 중력에 의해 이송되므로, 종래발명에 개시된 직립상태의 하우징과 달리 본 발명에 따른 회전망체는 완만한 경사 때문에 골재가 급속하게 장치를 통과하지 않고 서서히 통과하므로 박리 및 입형개선 효과를 실질적으로 향유할 수 있게 된다.First, when the recycled aggregate is introduced into the inlet 11 side of the rotating mesh 10 being rotated by the driving motor (not shown) as shown in FIG. 6 (a), the recycled aggregate is introduced into the guide plate of the rotating mesh ( It is rotated and rises with the guide plate 13 in the state loaded in 13). At this time, since the guide plate 13 is preferably inclined toward the rotation direction side of the rotating mesh 10, the guide plate 13 can rise without falling to near the rotational peak point of the rotating mesh 10. In addition, since the recycled aggregate is injected by gravity in the rotating mesh 10 installed inclined from the inlet 11 side to the outlet 12 side, the rotating mesh according to the present invention, unlike the housing of the upright state disclosed in the prior invention Because of the gentle slope, aggregates do not rapidly pass through the device, but pass slowly, so that the peel and improvement of the shape can be substantially enjoyed.

한편, 회전망체의 회전 정상점 부근에서 도6(b)에 도시된 바와 같이 재생골재는 하향 낙하하게 되는 데, 낙하도중에 상기 회전망체와 역방향으로 빠르게 회전하는 타격체의 박리용 타격봉에 의해 타격되어 그 표면에 부착된 모르타르가 충격에 의해 박리되게 된다. 특히, 상기 박리용 타격봉(21-1)은 지그재그로 형성되어 있기 때문에 낙하하는 위치가 상이할 지라도 각각의 타격봉에 의해 타격될 수 있다. 그리고, 타격에 의해 박리된 모르타르와 같은 이물질은 회전망체의 메쉬사이를 통해 배출된 후 이송컨베이어(30)를 따라 소정장소로 자동 회수되게 된다.On the other hand, as shown in Fig. 6 (b) near the top of the rotation of the rotating mesh, the recycled aggregates fall downward, while the dropping rod for peeling of the striking body rapidly rotating in the opposite direction to the rotating mesh during the fall. The mortar attached to the surface is hit by the impact to peel off by the impact. In particular, since the peeling striking rod 21-1 is formed in a zigzag, it may be hit by each striking rod even if the dropping position is different. Then, the foreign matter such as mortar peeled off by the blow is discharged through the mesh of the rotating mesh is automatically recovered to a predetermined place along the conveying conveyor (30).

상기와 같은 박리작용은 전술한 바와 같이 타격체(20) 상단에서 2/3 부분까지 형성된 박리용 타격봉(21-1)에 의해 이루어지는 것이고, 점차 이송되어 타격체 상단에서 2/3 되는 부분부터는 재생골재는 입형골재용 타격봉(21-2)에 의해 입형이 개선된다. 즉, 박리용 타격봉(21-1)에 비해 좀 더 조밀하게 형성되지만 그 직경은 1cm 내지 2cm로 박리용 타격봉에 비해 작은 입형개선용 타격봉(21-2)에 의해 골재가 자주 부딪치게 하여 각진 모서리의 입형을 개선되게 된다.As described above, the peeling action is performed by the peeling striking rod 21-1 formed from the upper portion of the striking body 20 to 2/3, and is gradually transferred from 2/3 at the top of the striking body. The recycled aggregate is improved in shape by the striking rod 21-2 for the granular aggregate. That is, it is more densely formed than the peeling rod 21-1, but its diameter is 1cm to 2cm, so that the aggregates are frequently bumped by the small-sized improvement rod 21-2 compared to the peeling rod. The shape of the angled edge is improved.

이와 같이 본 발명은 타격봉의 직경과 배치량을 위치에 따라 달리함으로써 박리를 위한 타격과 입형개선을 위한 타격이 선택적으로 이루어져 보다 양질의 재생골재를 획득할 수 있다는 잇점이 있다.As described above, the present invention has an advantage in that the impact for peeling and the impact for the improvement of the shape of the impacting rod can be selectively obtained by varying the diameter and the amount of placement of the striking rod, thereby obtaining a better recycled aggregate.

이상에서 설명한 바와 같이, 본 발명에 따른 재생골재의 표면박리 및 입형개선 장치는 투입된 재생골재가 저속으로 장치를 통과하게 하여 박리작업과 입형개선작업이 충분히 진행되어 양질의 재생골재를 획득할 수 있다는 효과가 있다. 또한, 본 발명은 타격봉의 직경과 배치량을 위치에 따라 달리하여 박리를 위한 타격과 입형개선을 위한 타격이 선택적으로 이루어질 수 있으며, 박리작업과 동시에 박리된 모르타르가 자동배출되므로 작업이 용이하다는 잇점이 있다.As described above, the surface peeling and granular improvement apparatus of the recycled aggregate according to the present invention allows the recycled aggregate introduced to pass through the device at a low speed so that the peeling operation and the granular improvement work are sufficiently performed to obtain a high quality recycled aggregate. It works. In addition, the present invention can be selectively made by the blow for the separation and the blow for improvement of the shape by varying the diameter and the amount of placement of the striking rod, the ease of operation because the peeled mortar is automatically discharged at the same time as the peeling operation There is this.
