Road waste asphalt mixture recovery processing equipment and method
The invention discloses road waste asphalt mixture recovery processing equipment and method, and relates to the technical field of road waste asphalt mixture recovery, and the road waste asphalt mixture recovery processing equipment comprises an extraction tank, a mixed oil tank, an evaporation tank, an extraction agent turnover tank, a vacuum pump and a compressor, the extraction tank is provided with a to-be-extracted material feeding port, a vacuumizing port, an extracting agent adding port, a mixed oil outlet and a stone outlet, and a black asphalt milling material with the particle size of 1-4.75 mm serves as a to-be-extracted material and is added into the extraction tank through the to-be-extracted material feeding port; according to the invention, a color sorting technology and a subcritical extraction technology are adopted to separate and extract a mixture milled from a highway pavement, and each part of material extracted after separation can be reused as a new raw material; and the extracted milling materials are separated again by virtue of a color sorting technology, so that the utilization rate of stones is improved, the regeneration rate of stone resources is ensured, and the influence on the environment is reduced.
本发明公开一种公路废旧沥青混合料回收处理设备及方法，涉及公路废旧沥青混合料回收技术领域，包括萃取罐、混合油罐、蒸发罐、萃取剂周转罐、真空泵和压缩机，所述萃取罐设有待萃取物料进料口、抽真空口、萃取剂加入口、混合油出口和石料出口，粒径为1mm‑4.75mm的，且颜色呈黑色的沥青铣刨料作为待萃取物料通过待萃取物料进料口加入萃取罐；本发明采用色选技术和亚临界萃取技术对公路路面铣刨下来的混合料进行分离并萃取，分离后萃取出来的各部分材料可以作为新的原料进行再利用；并借助色选技术对萃取完的铣刨料再次进行分离，提高了石料的利用率，保证了石料资源的再生率且减少了对环境的影响。
