Description
技术领域technical field
本发明涉及沥青生产设备领域，特别是涉及一种细集料自抛丸的沥青铣刨料处置系统及方法。The invention relates to the field of asphalt production equipment, in particular to a fine aggregate self-blasting asphalt milling material disposal system and method.
背景技术Background technique
沥青路面再生技术是一项新的沥青路面修筑技术,能够节约大量的沥青、砂石等原材料,同时有利于处理废料、保护环境,是一种经济、绿色环保施工技术。沥青路面的再生是将旧沥青路面经过翻挖、回收、破碎、筛分后，与再生剂、新沥青材料、新矿料等按一定比例重新拌和混合料,使之能够满足一定的路用性能并用其重新铺筑路面的一套工艺技术。Asphalt pavement regeneration technology is a new asphalt pavement construction technology, which can save a lot of raw materials such as asphalt, sand and gravel, and at the same time is beneficial to waste disposal and environmental protection. It is an economical and green construction technology. The regeneration of asphalt pavement is to re-mix the old asphalt pavement with regeneration agent, new asphalt materials, new mineral materials, etc. in a certain proportion after excavation, recycling, crushing and screening, so that it can meet certain road performance. And use it to re-pave the road with a set of technology.
废旧沥青路面再生过程中，旧料的级配、废旧沥青含量等对废旧沥青路面再生效果影响显著。旧沥青路面经铣刨破碎以后得到的大多是旧矿料与旧沥青粘结成的“团块”。“团块”表层黏附的废旧沥青处理不充分，会对新再生沥青混合料的级配与沥青含量产生较大的影响，使得再生沥青路面高低温性能变差，大大缩短使用寿命。During the regeneration process of waste asphalt pavement, the gradation of old materials and the content of waste asphalt have a significant impact on the regeneration effect of waste asphalt pavement. After the old asphalt pavement is milled and broken, most of the "agglomerates" formed by the bonding of old mineral materials and old asphalt are obtained. Insufficient treatment of the waste asphalt attached to the surface of the "clump" will have a greater impact on the gradation and asphalt content of the new recycled asphalt mixture, making the high and low temperature performance of the recycled asphalt pavement worse and greatly shortening the service life.
目前常用的再生料筛分方法,是将再生原料采用破碎机将再生料打散,然后采用圆振动筛或者直线振动筛将再生料分成0-5mm、5-10mm、10-20mm等产品，最后按照选定再生方法应用到沥青路面再生中。现有的筛分方法效率低下，而且无法去除沥青表面的沥青膜，因此无法充分的对废旧沥青混合料中的旧集料与旧沥青进行充分地利用，这对道路工程废旧沥青路面再生技术的发展产生了极其不利的影响。At present, the commonly used screening method for recycled materials is to use a crusher to break up the recycled materials, and then use a circular vibrating screen or a linear vibrating screen to divide the recycled materials into 0-5mm, 5-10mm, 10-20mm and other products, and finally It is applied to the regeneration of asphalt pavement according to the selected regeneration method. The existing screening method is inefficient and cannot remove the asphalt film on the asphalt surface, so the old aggregate and old asphalt in the waste asphalt mixture cannot be fully utilized. Development has had an extremely negative impact.
