摘要： Disclosed herein is a method and apparatus for separating and recycling waste asphalt concrete from construction waste, in which only waste asphalt concrete is separated from construction waste including various types of waste such as waste concrete, soil and sand, etc., upon disposal of the construction waste, and then recycled as useful material. The separation method of the current invention, including feeding collected construction waste, crushing the construction waste and removing a metal material, transferring and sorting, washing and removing floating materials, and re-circulating to improve the shape of particles, includes a first step of sorting the construction waste after having undergone washing to remove impurities according to a particle size using a sorting screen; a second step of guiding the construction waste having a predetermined particle size into a reversed funnel-shaped base; a third step of distributing the construction waste positioned in the base into a plurality of transfer passages and subsequently transferring the distributed waste; a fourth step of sensing the washed waste asphalt concrete, transferred from the third step, from a short distance depending on a unique color or a chemical reaction thereof to detect only the waste asphalt concrete; a fifth step of selectively opening a plurality of air spray nozzles positioned at an upper portion of the transfer passage to spray air in response to an electrical signal applied as a result of the performance of the fourth step, which are connected to position detection means so that selection among the air spray nozzles and orientation of the air spray nozzles toward the waste asphalt concrete positioned adjacent to a discharge port are controlled; a sixth step of forcibly returning the waste asphalt concrete along with general construction waste to the fourth step; and a seventh step of transferring the discharged waste asphalt concrete to a storage location. In addition, specific treatment means at each step is provided.
摘要翻译：本发明公开了一种从施工废弃物中分离回收废沥青混凝土的方法和装置，其中只有废沥青混凝土与建筑废物分离，包括废弃混凝土，土壤和沙等各种类型的废弃物，建筑废料，再循环再用作有用的材料。本发明的分离方法包括：收集建筑垃圾，破碎施工废弃物和去除金属材料，转移和分选，洗涤和除去浮动材料，并重新循环以改善颗粒的形状，包括第一步骤在经过洗涤之后对施工废料进行分选以使用分选筛根据粒度除去杂质; 将具有预定粒度的建筑垃圾引导到反向的漏斗形基座中的第二步骤; 将位于基座中的建筑废料分配到多个输送通道中并随后转移分散废物的第三步骤; 第四步，根据独特的颜色或化学反应，从短距离传感第三步骤的废沥青混凝土，仅检测废沥青混凝土; 选择性地打开位于传送通道的上部的多个空气喷嘴的第五步骤，以响应由于执行第四步的结果施加的电信号而喷射空气，这些连接到位置检测装置空气喷嘴之间的选择和空气喷嘴朝向与排放口相邻的废沥青混凝土的方位的控制; 将废沥青混凝土与一般建筑垃圾一起强制退回第四步; 以及将排出的废沥青混凝土输送到储存位置的第七步骤。此外，提供每个步骤的具体处理手段。
