Description
본 발명은 레미콘 슬러지(RSW)의 고효율 재처리장치에서 핵심부분인 건조 절단 챔버에 관한 것으로서, 더욱 상세하게는 레미콘 슬러지를 이송하고 건조하며 절단하는 일련의 과정으로 이루어져 있고, 기존에는 각 단위 작업을 분리해서 처리하였으므로 작업시간과 설치 공간이 비효율적이었다. 즉, 레미콘 슬러지(Remicon Sludge Waste)의 최종 생산량을 기준으로 각 단위 작업부의 수치 및 능력을 계산하여 각 단위작업을 연속적으로 처리할 수 있게 하여 기존의 작업 공정중에 발생하는 여러 가지 비효율성을 최소화 하고 생산력을 극대화시킬 수 있도록 하는 연속 공정에 의한 레미콘 슬러지(Remicon Sludge Waste) 재처리 장치에서 건조 및 절단챔버에 관한 것이다.The present invention relates to a dry cutting chamber which is a key part of a high-efficiency reprocessing device of ready-mixed concrete sludge (RSW), and more particularly, consists of a series of processes for transporting, drying and cutting ready-mixed concrete sludge. The separate processing resulted in inefficient working time and installation space. In other words, each unit work can be processed continuously by calculating the number and capacity of each unit work on the basis of the final production of Remicon Sludge Waste and minimizing various inefficiencies in the existing work process. It relates to a drying and cutting chamber in a remicon sludge waste reprocessing apparatus by a continuous process to maximize the productivity.
우리나라는 연간 약 1억㎥ 정도의 레미콘이 생산되고 있다. 각 공장마다 양의 차이는 있지만 일반적으로 1㎥당 3-10kg 정도, 연간 30-100만톤의 레미콘 슬러지가 발생되는데, 그 처리비용을 톤당 약 3만원으로 보았을 경우 연간 90-300억원의 처리비용이 발생하게 된다. 통상 타설작업이 끝난 후 공장으로 돌아오는 레미콘 운반차는 지정된 장소에서 세척되는데, 이때 발생되는 슬러지는 수집처리된다. 레미콘 슬러지는 일반적으로 필터 프레스(filter press)로 수분을 제거한 후 공공 매립지에서 안정 처리되는 것이 원칙이나, 지상에 불법 투기되기도 한다. 이러한 기존의 매립방법은 매립지반을 연약화 시키고, 건조되면 분진 등이 발생된다. 또한 레미콘 슬러지가 안전과정을 거치지 않고 매립지에 처리되어 물과 접촉하게 되면 주변의 수질을 강한 알칼리성으로 변화시키기 때문에 환경적으로 안전한 폐기 장소 확보와 위생처리에 많은 어려움이 있다. 따라서 막대한 경비가 따르는 매립보다는 재활용이 요구된다.In Korea, about 100 million ㎥ of ready-mixed concrete is produced annually. Although there is a difference in quantity at each plant, it generally generates 3-10kg per m3 and 30-100 million tons of ready-mixed sludge per year. When the processing cost is about 30,000 won per ton, the processing cost of 90-30 billion won per year Will occur. Normally, the ready-mixed concrete trucks, which are returned to the factory after finishing work, are washed at a designated place, and the sludge generated is collected and treated. Ready-mixed sludge is generally a filter press to remove moisture and then be stabilized in public landfills, but it is also illegally dumped on the ground. The existing landfill method is to weaken the landfill ground, dust is generated when dried. In addition, when ready-mixed sludge is treated in landfill without undergoing a safety process, the surrounding water quality is changed to strong alkaline, which makes it difficult to secure an environmentally safe disposal site and sanitary treatment. Therefore, recycling is required rather than huge landfills.
그러나 레미콘 슬러지는 수경성을 보이지 않는다는 단점 이외에, 입도 및 화학성분 등을 감안하여 볼 때 콘크리트용 방수제, 경량 기포 콘크리트 및 시멘트의 원료로 사용될 수 있는 가능성을 보여주고는 있으나, 회수에 따르는 비용이 너무 크기 때문에 재활용 사례가 거의 없는 실정이다. 또한 플라스틱이나 타이어의 충전제, 경량 골재용 재료로서의 이용 가능성이 제시되기도 하였지만 경제적 회수 처리의 문제가 여전히 해결되지 아니한 관계로 이 역시 적용이 불투명한 실정이다.However, in addition to the disadvantage of not showing hydraulic properties, ready-mixed sludge shows the possibility of being used as a raw material for waterproofing concrete, lightweight foamed concrete and cement in view of particle size and chemical composition, but the cost of recovery is too high. As a result, there are few recycling cases. In addition, the use of plastics or tires as fillers or materials for lightweight aggregates has been suggested, but the application of the economic recovery process has not been solved.
이와 같이, 환경적인 차원에서 레미콘 슬러지의 재활용에 대한 요구는 계속 증대되어 레미콘 슬러지의 재활용이 시급한 실정이나, 기존의 처리방법은 주로 매립에 의존하였고, 회수 처리장치는 기본적인 탈수에 국한된 장치만 있었기 때문에, 레미콘 슬러지의 재활용을 위해 젖은 상태의 레미콘 슬러지를 건조하고 분말상태로 만들어 유동화제 및 충전제를 혼합하는 일련의 작업을 연속적으로 처리하는 재처리 장치를 고안하였다.As such, there is an urgent need for recycling ready-mixed concrete sludge at an environmental level. However, it is urgent to recycle ready-mixed concrete sludge. In order to recycle ready-mixed concrete sludge, we designed a reprocessing device to continuously process a series of operations in which wet ready-mixed sludge is dried and powdered to mix a fluidizing agent and a filler.
본 발명은 이러한 일련의 시스템의 핵심부분인 건조,절단 챔버에 관한 것으로서, 더욱 상세하게는 레미콘 슬러지를 이송하고 이를 절단하며 이러한 일련의 과정에서 건조를 동시에 함으로써 작업공정 중에 여러 가지 생성되는 비효율성을 없애고 생산력을 극대화시킬 수 있도록 하는 고효율 건조 절단 장치에 관한 것이다.The present invention relates to a drying and cutting chamber which is an essential part of such a series of systems, and more particularly, to transport and cut ready-mixed concrete sludge and simultaneously dry in such a series of processes, thereby reducing various inefficiencies generated during the working process. It relates to a high efficiency dry cutting device that can be eliminated and maximize the productivity.
따라서, 본 발명은 레미콘 슬러지를 재처리하기 위한 일련의 시스템의 핵심과정인 슬러지의 건조 및 절단과정을 동시에 할 수 있는 챔버를 개발하는데 그 목적이 있다. 이를 이루기 위해 다단 연속공정 라인으로 구성된 챔버를 제작한다.Accordingly, an object of the present invention is to develop a chamber capable of simultaneously drying and cutting sludge, which is a core process of a series of systems for reprocessing ready-mixed sludge. In order to achieve this, a chamber composed of a multi-stage continuous process line is manufactured.
최초 레미콘 슬러지를 이송 및 절단시키면서 평균 2.5cm정도의 입자를 얻고, 다음단계에서는 평균 1.5cm의 입자를 다음 단에서는 더욱 잘게 부서진 입자를 얻으면서 동시에 챔버에 열을 가함으로써 건조시키는 것이다. 즉, 이러한 다단을 거치면서 슬러지입자의 직경은 계속 감소하고 이를 통해 건조효율을 높일 수 있는 것이다. 결국 이러한 과정을 거치면서 수분이 많은 슬러지는 잘게 부서진 건조된 슬러지를 얻고자 하는 것이다.While conveying and cutting the first ready-mixed concrete sludge, an average particle size of about 2.5 cm is obtained, and in the next step, an average particle size of 1.5 cm is obtained by further heating the chamber while simultaneously obtaining finely broken particles in the next stage. In other words, the diameter of the sludge particles continues to decrease through this multi-stage, thereby increasing the drying efficiency. Eventually, this process is to get the watery sludge finely crushed dried sludge.

상기와 같은 목적을 달성하기 위한 본 발명의 특징에 따르면, 레미콘슬러지(Remicon Sludge Waste)를 재활용하기 위한 시스템을 고려해 볼 때 그 핵심 부분의 하나로써 건조공정과 절단공정을 하나의 챔버안에서 동시에 하는 것이다. 이를 이루기 위한 여러 가지 제어 변수가 있지만 우선 건조하기 위한 공급열량을 계산하는 것이 중요하다. 이를 위해 미니 챔버를 제작하고 실험을 통해 공급 열량값을 결정하는 것이다. 또한 이송날개와 절단판의 간격을 통해 슬러지의 직경을 제어할 수 있다. 레미콘 슬러지(Remicon Sludge Waste)는 그 강도가 그리 크지 않기 때문에 절단판과 이송날개 및 그 시스템의 재료는 문제되지 않는다.According to a feature of the present invention for achieving the above object, when considering a system for recycling Remicon Sludge Waste (A), one of its core parts is to simultaneously perform the drying process and the cutting process in one chamber. . There are several control variables to achieve this, but first it is important to calculate the calorific value of the heat to dry. To do this, a mini-chamber is fabricated and the supply calories are determined through experiments. It is also possible to control the diameter of the sludge through the gap between the feed blade and the cutting plate. Remicon Sludge Waste is not so strong that the cutting plates, feed vanes and materials of the system are not a problem.
이하, 본 발명을 첨부 도면에 의거 더욱 상세히 설명하면 다음과 같다. 도 1은 본 발명을 간략하게 제시한 그림이다. 이는 개념도라 할 수 있는데 그림에서 (1)은 현장에서 사용한 후 남은 레미콘 슬러지(Remicon Sludge Waste)가 들어가는 입구이다. 이때 슬러지는 상당한 수분을 포함하고 있으며 그 강도가 크지 않기 때문에 쉽게 부서질 수 있는 재료이다. (2), (3), (4)는 열풍을 불어넣기 위한 입구로 이해하기 쉽게 개념적으로 표현한 것이다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. 1 is a diagram briefly presenting the present invention. This is a conceptual diagram. In the figure, (1) is the entrance to Remicon Sludge Waste left after using it in the field. Sludge is a material that can be easily broken because it contains considerable moisture and its strength is not large. (2), (3), and (4) are conceptually expressed as easy to understand as an entrance for blowing hot air.
또한 (5)는 건조절단 챔버를 통과한 슬러지가 나오는 출구로써 잘게 부서진 건조된 슬러지가 나오게 된다. 이때 이 시스템은 슬러지 재활용 시스템의 일부이기 때문에 (5)는 전체 재활용 시스템에서 볼 때 분쇄기와 연결이 될 것이다. 부연설명으로 분쇄기를 통과한 슬러지는 고운 가루가 되는데 이 가루와 다른 물질을 첨가함으로써 슬러지를 재활용하는 것이다.In addition, (5) is the outlet of the sludge passed through the drying cutting chamber comes out of the finely broken dried sludge. Since this system is part of the sludge recycling system, (5) will be connected to the grinder in the overall recycling system. As a side note, the sludge passed through the grinder becomes a fine powder, which is recycled by adding the powder and other materials.
도 2는 이송날개와 절단부를 하나의 part로 나타낸 그림이다. (6)은 개개의 이송날개을 보여준 개념도인데 (7)의 축을 중심으로 회전한다. (9)는 밑받침이다.(10)에서는 이송날개에 대한 형상을 단순한 철판으로 만들지 않고 지름방향으로 좀 더 두껍게 제작함으로써, 슬러지의 이송 효율을 최대화하기 위해 고안된 형상이다.Figure 2 is a view showing the transfer blade and the cutting part in one part. (6) is a conceptual diagram showing the individual feed vanes, rotated about the axis of (7). (9) is an underlay. In (10), the shape of the feed wing is designed to maximize the transport efficiency of the sludge by making it thicker in the radial direction instead of making a simple steel plate.
도 3은 이송날개와 절단의 원리를 알기 쉽게 표현한 개념도 이다. 즉, 회전축을 중심으로 이송날개가 회전을 하면 슬러지는 밑받침을 거쳐 다음 칸으로 이동하게 되는데, 이때 밑받침에 슬러지를 절단할 수 있는 절단판이 회전운동을 하는 슬러지를 절단하는 것이다. (12)는 절단판의 두께를 나타낸 것이고, (13)은 절단판사이의 간격을 나타낸 것이다. 바로 이 두가지를 조절함으로써 슬러지 입자의 크기를 결정하는 것이다. 본 발명의 건조,절단 챔버는 다단으로 이루어져 있는데 각 단마다 (12)와 (13)의 크기가 다르며 이를 통해 슬러지 입자의 크기를 점점 작게 만드는 것이다. 결국 (1)을 통해 들어간 레미콘 슬러지(Remicon Sludge Waste)는 (5)를 통해 지름 잘게 부서진 건조된 슬러지로 되는 것이다.3 is a conceptual diagram expressing the principle of the cutting blade and cutting. That is, when the feed blade is rotated around the rotation axis, the sludge is moved to the next compartment through the underlay, wherein the cutting plate capable of cutting the sludge on the underlay is to cut the sludge to rotate. (12) shows the thickness of the cutting plates, and (13) shows the spacing between the cutting plates. By adjusting these two things, the size of the sludge particles is determined. The drying and cutting chamber of the present invention is composed of multiple stages, each stage having different sizes of (12) and (13), through which the size of the sludge particles is made smaller. Eventually, Remicon Sludge Waste entered through (1) becomes dried sludge that is finely broken through (5).
이상에서 살펴본 바와 같이, 본 발명의 건조절단 챔버는 종래의 공정인 건조와 절단을 따로따로 함으로써 야기되는 저 효율성과 단점을 보완하고자, 열풍을 분사하는 챔버안에 3단의 순차적인 이송 및 절단 시스템을 제작하여 현장에서 쓰이고 남은 레미콘 슬러지를 재활용하는 장치의 일부로써 고효율의 재활용시스템을 만들 수 있게 한다. 특히 이송 및 절단 시스템을 실험 및 이론적인 연구를 통해 가장 효과적인 이송날개의 기하학적형상을 제작하였으며 이를 통해 고효율의 건조절단 챔버를 제작할 수 있는 것이다. 또한 이 시스템의 특징으로서 다단식의 건조 절단시스템을 도입함으로써 건조효율을 극대화 시키는 방안이 사용되었다.As described above, the drying cutting chamber of the present invention is a three-sequential sequential transfer and cutting system in the chamber for injecting hot air to compensate for the low efficiency and disadvantages caused by the separate drying and cutting process of the conventional process As part of the equipment to recycle the ready-mixed concrete sludge left in the field, it is possible to make a highly efficient recycling system. In particular, through the experimental and theoretical studies of the transfer and cutting system, the most effective transfer blade geometry was produced. Through this, the highly efficient dry cutting chamber can be manufactured. In addition, as a feature of this system, a method of maximizing drying efficiency was introduced by introducing a multi-stage dry cutting system.
따라서 본 발명은 레미콘 슬러지 재활용시스템에서 핵심부분을 차지함으로써 연간 30-100만톤의 레미콘 슬러지로 인해 발생되는 자연환경의 파괴와 막대한 처리비용을 해결하는데 커다란 효과가 있을 것이다.Therefore, the present invention will take a key part in the ready-mixed concrete sludge recycling system will have a great effect in solving the enormous disposal cost and destruction of the natural environment caused by 30-100 million tons of ready-mixed concrete sludge per year.
