본 발명은 표면이 박리된 재생골재를 획득하는 방법에 관한 것이다. 보다 상세하게는 건설폐기물의 중간처리공정을 통해 생산되는 재생골재의 품질을 보다 향상시키기 위한 일환으로서, 회전식 마찰 작용으로 재생골재의 표면을 박리시키는 재생골재용 표면박리기를 사용하여 표면이 박리된 재생골재를 획득하는 방법에 관한 것이다.The present invention relates to a method for obtaining a recycled aggregate having the surface peeled off. More specifically, in order to further improve the quality of recycled aggregates produced through the intermediate treatment process of construction wastes, the surface of the recycled aggregates is peeled off by using a surface peeler for recycled aggregates, which peels off the surface of the recycled aggregates by a rotating friction action. It relates to a method of obtaining aggregate.

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, 상기 중간처리공정은 수거된 건설폐기물을 파쇄하는 공정과, 파쇄된 파쇄물에서 고철류, 폐지류, 폐목재, 토사등을 선별한 후 세척하여 이들을 회수하는 공정과, 상기 파쇄된 건설폐기물을 재파쇄, 및 재선별하여 소정크기의 입경을 갖는 재생골재를 획득하는 공정으로 구성된다.Looking at the intermediate treatment process of the construction wastes, the intermediate treatment process is a process of crushing the collected construction waste, and scraping and scraping scrap metal, waste paper, waste wood, earth and sand to recover them And reprocessing and shredding the shredded construction waste to obtain recycled aggregate having a particle size of a predetermined size.

하지만, 이와 같은 공정을 통해 획득된 재생골재라도 골재 표면에 부착된 시멘트 모르타르 및 이물질 등과 같은 슬러지로 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 aggregate obtained through such a process has poor granularity compared with natural aggregates due to sludge such as cement mortar and foreign substances attached to the aggregate surface, resulting in poor appearance and aggregate surface and mortar during field application. There is a problem that the adhesive strength of the and decreases, the absorption rate is high and the strength of the recycled aggregates is lowered.

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 골재에는 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 only used in concrete, filler concrete, non-structural concrete of buildings, etc., but it is not used in one type aggregate that is mixed in bridge lower hole, fusion wall, tunnel lining hole.

이하, 첨부된 도면을 참고하여 본 발명을 보다 상세하게 설명한다. 첨부된 도1은 본 발명에 따른 표면이 박리된 재생골재를 획득하는 공정을 개략적으로 도시한 플로우 차트이며, 도2 및 도3은 본 발명에 따른 표면이 박리된 재생골재를 획득하는 공정에서 바람직하게 사용될 수 있는 재생골재용 표면박리기의 일례를 도시한 것이고, 도4 및 도5는 본 발명에 따른 표면이 박리된 재생골재를 획득하는 공정에서 바람직하게 사용될 수 있는 재생골재용 표면박리기의 일례를 도시한 것이다.Hereinafter, with reference to the accompanying drawings will be described in detail the present invention. 1 is a flow chart schematically illustrating a process of obtaining a recycled aggregate with a peeled surface according to the present invention, and FIGS. 2 and 3 are preferred in a process of obtaining a recycled aggregate with a peeled surface according to the present invention. 4 shows an example of a surface peeler for reclaimed aggregate, which can be used to make it possible. FIGS. 4 and 5 illustrate a surface peeler for recycled aggregate that can be preferably used in a process of obtaining a recycled aggregate having a surface peeled according to the present invention. An example is shown.

본 발명에 따른 표면이 박리된 재생골재를 획득하는 공정은 개략적으로 도1 에 도시된 바와 같이, 재생골재 획득공정과, 상기 획득된 재생공정의 표면을 박리시키는 표면박리공정과, 상기 표면박리공정 과정에서 박리된 미분을 회수하는 미분회수공정과, 최종적으로 표면이 박리된 재생골재를 획득하는 공정을 포함한다.The process of obtaining the recycled aggregate with the surface peeled off according to the present invention is schematically shown in Figure 1, the process of obtaining a recycled aggregate, a surface peeling process for peeling the surface of the obtained regeneration process, and the surface peeling process And a process for recovering fine powder separated in the process, and a process for obtaining recycled aggregate from which the surface was finally peeled off.

상기 재생골재 획득공정은 수거된 건설폐기물을 파쇄하는 공정과, 파쇄된 파쇄물에서 고철류, 폐지류, 폐목재, 토사등을 선별한 후 세척하여 이들을 회수하는 공정과, 상기 파쇄된 건설폐기물을 재파쇄, 및 재선별하여 소정크기의 입경을 갖는 재생골재를 획득하는 공정을 포함한다. 물론 필요에 따라서는 어느 공정이 생략될 수 있고, 필요에 따라서는 어느 공정이 반복 수행될 수 있음은 당연하다. The recycling aggregate obtaining process is a process of crushing the collected construction waste, the process of sorting scrap metal, waste paper, waste wood, earth and sand from the crushed crushed and washed to recover them, and the crushed construction waste Crushing and reselecting to obtain a recycled aggregate having a particle size of a predetermined size. Of course, any process may be omitted if necessary, and any process may be repeatedly performed as necessary.

한편, 상기 획득된 재생골재는 상기 공정을 거쳤다 하더라도 골재 표면에 부착된 시멘트 모르타르 및 이물질 등과 같은 슬러지로 인해 천연골제에 비해 품질이 양호하지 못한 2종 내지 3종 골재이다. 하지만, 슬러지가 표면에 부착된 재생골재는 이하에서 언급될 표면박리공정을 통해, 구체적으로는 회전식 마찰 작용으로 재생골재의 표면에 부착된 슬러지를 박리시킬 수 있는 재생골재용 표면박리기를 사용을 통해 슬러지를 박리시킴으로써 천연골재와 실질적으로 동일한 품질의 재생골재를 획득할 수 있는 것이다. On the other hand, the obtained recycled aggregates are two or three kinds of aggregates that are not of good quality compared to natural aggregates due to sludge such as cement mortar and foreign matters adhered to the aggregate surface even though the above-mentioned process passes. However, the recycled aggregate to which the sludge is attached to the surface is subjected to the surface peeling process to be described below, specifically, through the use of a surface peeler for the recycled aggregate that can peel the sludge adhered to the surface of the recycled aggregate by the rotary friction action. By peeling the sludge it is possible to obtain a recycled aggregate of substantially the same quality as natural aggregate.

이를 위해, 본 발명에서는 회전식 마찰 작용을 구현하는 재생골재용 표면박리기를 사용하여 재생골재의 표면의 슬러지를 박리시키는 것을 제안한다. 상기 표 면박리기는 특별히 한정되지 않으며, 회전식 마찰 작용을 구현하는 것이면 어느 것이라도 채용할 수 있다. 따라서, 이하에서 설명될 표면박리기는 본 발명에 채용될 수 있는 표면박리기의 바람직한 일례로서 제안된 것일 뿐 한정하기 위해 제안된 것이 아님을 미리 밝혀둔다.To this end, the present invention proposes to use the surface peeler for recycled aggregates to implement a rotary friction action to peel the sludge of the surface of the recycled aggregates. The surface peeler is not particularly limited, and any surface peeler may be employed as long as it implements a rotary frictional action. Therefore, it will be apparent that the surface peeler to be described below is only proposed as a preferred example of the surface peeler that can be employed in the present invention and is not proposed to limit.

도2 및 도3에 도시된 표면박리기(100)는 도시된 바와 같이 재생골재가 투입되는 호퍼(110)와; 일측에는 상기 호퍼(110)를 통해 낙하되는 골재가 투입되는 투입공(121)이 형성되며, 타측에는 골재가 배출되는 배출공(122)이 형성되며, 내주면에는 소정의 요철부(123)가 형성되되, 투입공(121)이 형성된 측에서 배출공(122)이 형성된 측으로 경사지게 설치된 케이스(120)와; 상기 케이스(120)의 내부에 장착되되, 외주면에는 소정의 요철부(131)가 형성된 회전드럼(130)과; 상기 회전드럼(130)을 회전시키도록 상기 회전드럼(130)과 축상 결합된 구동수단(140)과; 상기 케이스(120)를 지지하기 위한 지지대(150)를 포함하여 구성되는 것을 특징으로 한다.2 and 3, the surface peeling machine 100 includes a hopper 110 into which recycled aggregate is injected as shown; One side is formed with an input hole 121 into which the aggregate falls through the hopper 110 is formed, the other side is formed with a discharge hole 122 through which the aggregate is discharged, and a predetermined uneven portion 123 is formed on the inner circumferential surface thereof. The case 120 is inclined toward the side in which the discharge hole 122 is formed from the side in which the input hole 121 is formed; A rotating drum 130 mounted inside the case 120 and having a predetermined uneven portion 131 formed on an outer circumferential surface thereof; Drive means (140) axially coupled with the rotating drum (130) to rotate the rotating drum (130); It characterized in that it comprises a support 150 for supporting the case 120.

바람직하게는 상기 회전드럼(130)의 외주면에는 재생골재의 이송을 회전 안내하기 위한 안내 스크류(132)가 더 형성될 수 있으며, 상기 케이스(120)의 하측에는 재생골재의 마찰에 의해 발생된 골재의 박리미분이 여과되는 스크린부(125)가 형성될 수 있다. 또한, 상기 호퍼(110)의 입구에는 호퍼(110)에 투입되는 재생골재에 물을 분사하기 위한 분사노즐(180)이 마련될 수 있으며, 상기 지지대(150)는 케 이스의 기울기를 조절할 수 있도록 높이조절이 가능하도록 구성됨이 바람직하다. Preferably, the outer circumferential surface of the rotating drum 130 may be further formed with a guide screw 132 for guiding the rotation of the recycled aggregate, the lower side of the case 120 aggregate caused by the friction of the recycled aggregate The screen portion 125 through which the fine powder of the separation may be formed may be formed. In addition, the inlet of the hopper 110 may be provided with a spray nozzle 180 for injecting water to the recycled aggregate is introduced into the hopper 110, the support 150 to adjust the inclination of the case It is preferable to be configured to allow height adjustment.

또한, 상기 표면박리기(100)는 전면측에 상기 회전드럼(130)이 내부에 장착된 케이스(120)가 삽입 안착되는 삽입공(191)이 형성되며, 상측에 상기 호퍼(110)가 삽입 지지되는 지지공(192)이 형성되는 하우징(190)을 더 포함할 수 있다. 이 때, 상기 케이스가 삽입되는 하우징 전면의 삽입공(191)은 지지대(150)의 높이 조절에 의해 케이스(150)의 기울기가 조절될 때 하우징(190)과 케이스(120)간의 간섭이 방지되도록 상측공간이 더 개구될 수 있다.In addition, the surface peeling 100 is formed in the front side is inserted into the insertion hole 191 is inserted into the case in which the rotating drum 130 is mounted therein, the hopper 110 is inserted in the upper side It may further include a housing 190 in which the support hole 192 is supported. At this time, the insertion hole 191 of the front surface of the housing into which the case is inserted is prevented from interfering between the housing 190 and the case 120 when the inclination of the case 150 is adjusted by adjusting the height of the support 150. The upper space may be further opened.

이와 같이 구성된 표면 박리기의 작용을 설명한다. 호퍼에 통해 낙하된 재생골재는 케이스(120)의 내주면과 회전드럼(130)의 외주면 사이에 형성된 환형의 이송공간(V)으로 이송되게 되며, 회전드럼(130)의 회전에 의해 재생골재는 케이스의 요철부(123) 및 회전드럼의 요철부(131)에 각각 회전되면서 마찰될 뿐만 아니라 재생골재간 상호간 마찰되면서 표면박리가 이루어 진 후 배출슈트(S)를 통해 배출되며, 미도시된 골재회수 스크린에 의해 상기 표면박리공정을 통해 표면이 박리된 재생골재를 선별, 획득할 수 있게 된다. 한편, 상기 재생골재의 표면박리 작용으로 인해 발생되는 박리미분은 케이스의 하부에 마련된 스크린부(125)에 여과된 후 채집부(160)를 거쳐 이송수단(170)에 의해 소정의 장소로 회수되게 된다.The effect | action of the surface peeler comprised in this way is demonstrated. The recycled aggregate dropped through the hopper is transferred to the annular transfer space (V) formed between the inner circumferential surface of the case 120 and the outer circumferential surface of the rotary drum 130, the recycled aggregate is rotated by the rotation of the drum 130 Not only are rubbing on the uneven portion 123 and the uneven portion 131 of the rotating drum, but also the friction between the recycled aggregates and the surface peeling is made and discharged through the discharge chute (S), not shown aggregate recovery Through the surface peeling process by the screen it is possible to select, obtain the recycled aggregate peeled off the surface. On the other hand, the peeled fine powder generated due to the surface peeling action of the recycled aggregate is filtered by the screen portion 125 provided in the lower portion of the case to be recovered to a predetermined place by the transfer means 170 via the collecting unit 160 do.

상기 공정에 따르면, 재생골재 표면의 슬러지가 박리되기 때문에 슬러지로 인한 입형상태의 불량이 향샹되고 흡수력이 감소되어 고품질의 1종 골제용으로 활용할 수 있는 재생골재를 획득할 수 있게 된다.
