스크린 일체형 콘크리트용 순환 골재 박리장치{Mortar Exfoliation Device for Recycled Aggregates}Screen aggregate integrated circulating aggregate peeling device {Mortar Exfoliation Device for Recycled Aggregates}

본 발명은 콘크리트용 순환 골재 품질규격을 맞추기 위하여 골재에 포함된 모르타르를 박리시켜 분리 제거하는 콘크리트용 순환 골재 박리 장치에 관한 것이며, 특히 모르타르 박리와 스크린에 의한 선별이 단일장치에서 이루어지는 스크린 일체형 콘크리트용 순환 골재 박리장치를 제시함으로써 기존 도로공사용 순환골재 생산 공정의 최종 공정에 부가 적용하여 콘크리트용 순환 골재 생산 시스템으로 전환할 수 있는 콘크리트용 순환 골재 박리 장치에 관한 것이다.
The present invention relates to a circulating aggregate peeling device for concrete that peels and removes the mortar contained in the aggregate in order to meet the circulating aggregate quality standards for concrete, in particular for screen-integrated concrete where the mortar peeling and screening screening is made in a single device The present invention relates to a circulating aggregate delamination apparatus that can be converted into a circulating aggregate production system for concrete by applying to the final process of the existing circulating aggregate production process for existing road works.

구조물의 철거 과정에서 발생하는 폐콘크리트는 중간처리 공정을 거쳐 순환골재로 재활용된다.Waste concrete generated during the demolition of the structure is recycled to recycled aggregate through an intermediate treatment process.

폐콘의 중간처리는 다양한 규격의 파쇄능을 갖는 복수의 크러셔를 사용하여 재활용 용도의 골재 크기로 분쇄하는 파쇄공정과, 풍력· 자력 ·인력 등을 활용하여 철근이나 이물질을 선별분리하는 분리공정과, 다양한 규격의 스크린을 사용하여 재활용 용도에 의한 입도 크기로 분리하는 선별공정 등 일련의 연속적인 공정으로 이루어진다.Intermediate treatment of waste cones includes a crushing process that uses a plurality of crushers with various crushing crushers to crush the aggregate size for recycling, and a separation process for separating and separating reinforcing bars or foreign substances using wind, magnetic force, and manpower. It consists of a series of continuous processes, such as a screening process that separates screens of various sizes into particle sizes by recycling.

통상적인 중간처리공정에 의해 얻어지는 순환골재는 도로보조기층용 순환골재의 품질기술을 만족하지만 생산된 골재는 원골재 일부 표면에 모르타르가 피복된 상태로 존재하고, 적은 량이지만 점토가 일정부분 포함되어 있기 때문에 보다 고급 순환골재 용도인 콘크리트용 순환골재 용도로 용도로 사용할 수 없다. The recycled aggregate obtained by the conventional intermediate treatment process satisfies the quality technology of the recycled aggregate for the road auxiliary layer, but the produced aggregate has a mortar coated on a part of the raw aggregate, and a small amount of clay is contained. Therefore, it can not be used for the purpose of circulating aggregates for concrete which is the use of more advanced circulating aggregates.

원골재에 부착된 모르타르는 골재의 흡수율을 높이고, 알카리골재반응을 야기한다.Mortar adhering to raw aggregates increases the absorption of aggregates and causes alkaline aggregate reactions.

흡수율이 높은 골재를 콘크리트 배합에 사용하면 시멘트의 수화에 필요한 물이 골재에 흡수됨으로써 최대강도에 미치지 못한 상태로 수화과정이 종료되어 강도저하, 내구성, 수밀성, 동결융해에 대한 저항성이 떨어진다. When the aggregate with high absorption rate is used for concrete mixing, the water required for hydration of cement is absorbed by the aggregate so that the hydration process is terminated without reaching the maximum strength, resulting in poor strength, durability, watertightness, and resistance to freeze-thawing.

알카리골재반응은 미 수화 된 모르타르에 의해 이루어지며, 골재에 함유되어 있는 반응성 실리카가 시멘트의 칼륨, 나트륨이나 수산화칼슘과 반응하여 골재의 주변에 겔을 형성하고, 이것이 습기와 만나서 팽창과 균열 및 동결융해의 원인이 된다.Alkaline aggregate reaction is performed by unhydrated mortar, and the reactive silica contained in the aggregate reacts with potassium, sodium or calcium hydroxide in cement to form gel around the aggregate, which meets with moisture to swell, crack and freeze thaw. Cause.

순환골재에 포함된 점토는 시멘트페이스트와 철근과의 부착력을 감소시켜 콘크리트의 강도와 안정성에 영향을 미친다.Clay contained in recycled aggregates reduces the adhesion between cement paste and rebar, affecting the strength and stability of concrete.

따라서, 순환골재를 콘크리트 용도로 사용하기 위해서는 원골재에 포함된 모르타르의 박리제거 및 점토질 성분의 분리 제거가 필수적으로 요구되며, 그동안의 기술 개발노력을 통하여 다양한 방식에 의한 박리장치들이 제안되고 있다.Therefore, in order to use the recycled aggregate for concrete use, it is necessary to remove and remove the mortar contained in the raw aggregate and the separation and removal of the clay component, and peeling apparatuses using various methods have been proposed through the technology development efforts.

대한민국 등록특허 10-0943230는 드럼형 시멘트 페이스트 박리부를 따라 회전되면서 상승되는 재생잔골재에 드럼형 시멘트 페이스트 박리부의 임팩트패널부와 외벽 라이너의 빨래판 돌기에 의해 충격 파쇄 및 마찰 파쇄가 발생되도록 유도하는 박리장치를, 대한민국 공개특허 10-2012-0054796는 원추형 마찰판을 이용하여 순환골재와 마찰판 사이 그리고 순환골재 사이의 마찰력을 증대시켜 순환골재의 표면에 부착된 모르터를 제거하는 기술을 제시하고 있다.Republic of Korea Patent Registration 10-0943230 is a peeling device for inducing the impact fracture and friction crushing by the impact plate portion of the drum-type cement paste peeling portion and the washing plate projections of the outer wall liner to the regenerated fine aggregate is rotated along the drum-type cement paste peeling portion Korean Patent Laid-Open Publication 10-2012-0054796 proposes a technique for removing mortar attached to a surface of a circulating aggregate by increasing friction between the circulating aggregate and the friction plate and between the circulating aggregate using a conical friction plate.

이와 같은 기존 박리장치는 주로 타격에 의해 골재와 하우징 사이의 충돌 및 골재 상호간의 충돌을 유도하여 원골재에 부착된 모르타르를 털어내는 방식으로써 모르타르 박리에 효과적인 기술수단을 제공하고 있으나 원골재로부터 분리된 모르타르 및 시멘트 분말이 원재료와 함께 뒤섞인 상태로 박리공정이 종료됨으로 골재로부터 분리된 모르타르등의 미분 물질을 분리하기 위한 별도의 후 공정을 필요로 하며, 종래 이를 위하여 수 세척장치와 침전지 등의 부속설비를 추가로 설치함으로써 설비 비용과 운전비용이 증가되고, 설비를 위한 공간을 추가로 확보하여야 하며, 세척수가 결빙되는 동절기에는 가동을 중지해야 하는 등의 문제점이 있었다.Such a conventional peeling device mainly provides a technical means for peeling mortar by peeling the mortar attached to the raw aggregate by inducing a collision between the aggregate and the housing and a collision between the aggregates by the blow, but separated from the raw aggregate. As the peeling process is completed with the mortar and cement powder mixed with the raw materials, a separate post process is required to separate the fine powder such as mortar separated from the aggregate. By additionally installing the equipment cost and operating cost is increased, and additional space must be secured for the facility, there was a problem such as stopping the operation in winter when the wash water freezes.

도 1 및 2은 본 발명의 기본 구성을 도시하기 위한 것으로, 본 발명은, 폐콘크리트의 중간처리 공정에 의해 생산된 1차 순환골재를 투입하여 콘크리트용 순환골재를 생산하기 위한 콘크리트용 순환 골재 박리장치를 구성하며, 박리장치(200)와 선별장치(300) 및 골재이송덕트(400)가 단일 프레임(100)상에 구성된다. 1 and 2 are for showing the basic configuration of the present invention, the present invention, by inserting the primary recycled aggregate produced by the intermediate treatment process of waste concrete circulating aggregate for concrete to produce the recycled aggregate for concrete The apparatus constitutes an apparatus, and the peeling apparatus 200, the sorting apparatus 300, and the aggregate transfer duct 400 are configured on the single frame 100.

프레임(100)은, 각 구성요소를 지지하고, 설치 위치에 고정한 상태에서 운전 부하를 견딜 수 있도록 각각의 부재를 용착한 사각 틀체구조를 갖는다.The frame 100 has a rectangular frame structure in which each member is welded to support each component and to withstand the driving load in a fixed state at the installation position.

박리장치(200)는 상기 프레임에 설치되는 원통드럼(210)과 그 중심부에 설치한 교반기(220) 및 프레임에 지지된 상태에서 각기 적절한 속도로 회전할 수 있도록 구동장치(230)(240)가 결합된 구조를 갖는다. The peeling device 200 includes a cylindrical drum 210 installed in the frame, an agitator 220 installed in the center thereof, and a driving device 230 and 240 so as to rotate at an appropriate speed in a state supported by the frame. It has a combined structure.

상기 원통드럼(210)은 선단 골재투입구(211)와 후단의 골재배출구(212)가 연통되고 내측면에 일정 간격으로 파형돌기(213)가 형성된다.The cylindrical drum 210 is the front end aggregate inlet 211 and the rear end aggregate discharge port 212 is in communication with the corrugated protrusion 213 is formed at a predetermined interval on the inner surface.

파형돌기(213)는 골재와의 접촉에 의한 마찰효과를 높여 박리효과를 증진 시키기 위한 것으로, 단면상 삼각형 요철형태로 투입부에서 배출부까지 연속 형성할 수 있고, 길이 방향으로 환봉을 부착하여 요철을 형성할 수 있으며, 주물형태로 요철판을 형성하여 내면에 부착하는 형태로 구성할 수 있다.  Corrugated protrusion 213 is to increase the friction effect by the contact with the aggregate to enhance the peeling effect, can be formed continuously from the input to the discharge portion in the form of triangular irregularities on the cross-section, by attaching a round bar in the longitudinal direction It can be formed, it can be configured to form a concave-convex plate in the form of castings and to attach to the inner surface.

상기한 교반기와 원통드럼은 회전방향을 달리함으로써 박리효과를 향상할 수 있다. 즉, 회전방향이 각기 다름으로써 골재가 뭉쳐서 이동하지 않고 분산 이동하며, 골재 상호간의 충돌 기회도 높아져 박리효율이 향상되는 효과를 제공한다.The stirrer and the cylindrical drum can improve the peeling effect by changing the rotation direction. That is, since the rotation direction is different, the aggregates are dispersed and moved without being aggregated together, and the collision chance between the aggregates is also increased, thereby providing an effect of improving the peeling efficiency.

상기한 원통드럼은 저속 회전하고, 교반기는 원통드럼에 대하여 역회전하고 상대적으로 고속회전하여 투입된 골재 상호간의 충돌과 드럼 내면에서의 마찰 및 충격에 의해 투입된 골재 표면에 부착된 모르타르를 박리하는 작용을 하며, 박리된 골재는 골재배출구를 통하여 하부에 설치된 원통스크린으로 이송된다.
