Continuous production equipment and production process for recycled asphalt mixture
The invention relates to the technical field of asphalt production, in particular to recycled asphalt mixture continuous production equipment which comprises a new aggregate hopper, a continuous belt scale, a belt conveyor, a drying and heating roller, a combustor, a hot flue gas pipeline, a new and old material mixing and heating roller and an RAP hopper. After the new aggregate enters the new and old material mixing and heating roller, the hot new aggregate and the cold RAP can be fully mixed and rubbed, the RAP is heated by the heat of the new aggregate and the heat of the hot flue gas pipeline in the process, asphalt in the RAP is softened and melted after the RAP is heated to a certain temperature, and the asphalt can be transferred to the surface of the new aggregate in the mixing process; therefore, the necessary'old asphalt migration 'in the production process of the recycled asphalt mixture is realized, and the problems of new and old material temperature segregation, insufficient old asphalt migration, insufficient RAP adhesion heating roller, insufficient continuous stirring mixture uniformity and the like in the current RAP asphalt recycled mixture production in the industry are effectively solved.
本发明涉及沥青生产技术领域，尤其涉及了一种再生沥青混合料连续式生产设备，包括：新骨料斗、连续式皮带称、皮带机、烘干加热滚筒、燃烧器、热烟气管道、新旧料混合加热滚筒、RAP料斗。本发明通过新骨料进入新旧料混合加热滚筒后，热的新骨料和冷的RAP能够充分的进行混合、摩擦，过程中新骨料的热量以及热烟气管道的热量对RAP进行加热，RAP加热到一定温度后RAP中的沥青软化融化，在混合过程中可以转移到新骨料的表面，从而实现再生沥青混合料生产过程中必需的“旧沥青迁移”，有效解决了行业当下RAP沥青再生混合料生产中存在的新旧料温度离析、旧沥青迁移不够、RAP粘附加热滚筒、连续式搅拌混合料均匀性不够等问题。
