Description

一种连续式再生沥青混合料生产设备 技术领域
本发明涉及沥青混合料生产设备技术领域，特别涉及一种连续式再生沥青混合料生产设备。
背景技术
当前沥青混合料热再生技术中RAP再生形式主要为：
1.采用烘干滚筒对全部RAP加热后再与新料进行搅拌获得RAP沥青混合料——新骨料和RAP各自使用独立的烘干滚筒分别加热计量后投入到搅拌机，同时添加沥青及粉料进行搅拌成新的沥青混合料。在RAP加热过程中，由于颗粒大小不一，比表面积差异巨大。所以在同样的加热环境下不同粒径物料的加热不均衡。导致出现细料加热到所需温度时，粗料远未达到所需温度；或者粗料加热到所需温度时，细料中的沥青被烤焦老化失去功能。同时，由于细颗粒中沥青含量高，加热融化后会产生粘附，从而影响设备的正常使用。
2.将RAP按粒径大小分开处理，大颗粒RAP采用传统滚筒式烘干加热形式加热；细颗粒(粒径≤5mm)不经加热而直接投入搅拌缸与新骨料及加热后大颗粒RAP混合，通过将新骨料或大颗粒RAP加热到超过所需出料温度与细颗粒进行热传导将细颗粒加热到所需温度。该方式存在两方面问题：1)新骨料或大颗粒RAP温度不能无限加高，否则会破坏骨料的强度(一般情况下常规沥青混合料骨料温度不超过230摄氏度)，这就限制了RAP细颗粒的添加量；2)细颗粒中的含水与高温的骨料在搅拌缸中混合接触会瞬间产生大量水蒸气，影响设备的整体负压从而影响设备使用，同时还产生烟气外泄导致环境污染。
以上两种再生形式除上述的缺点外，还存在热烟气形成的风速将细颗粒吸走造成的混合料级配缺失以及颗粒磨损、粘附等一系列影响设备 运行的问题。
目前在将RAP粗料和细料一起进行热再生时，为了防止粘附滚筒，通常会采用柔性链条作为滚筒叶片，但是这种方式存在着加热效率低的问题。
另外，现有的再生沥青混合料生产设备通常是采用间歇式设计，既采用先加热后计量的方式，需要用到暂存仓和计量装置，容易出现降温后的沥青粘附暂存仓和计量称的问题。
