Low-carbon draining concrete production complete equipment and draining concrete production process
The invention provides low-carbon asphalt concrete production complete equipment and an asphalt concrete production process, and relates to the technical field of asphalt concrete production, the low-carbon asphalt concrete production complete equipment comprises a double-layer drying roller and a mixing main building, and the double-layer drying roller and the mixing main building are in a front-back process relation. The heated new aggregate and the unheated recycled material enter the interlayer between the inner cylinder and the outer cylinder, so that the purpose of heating the recycled material by utilizing waste heat emitted by the inner cylinder is achieved, the recycled material enters from the low end of the interlayer, is discharged from the high end of the interlayer and is reversely discharged, the recycled material is heated more sufficiently, the heat difference ratio between the recycled material and the new aggregate is small, and in the mixing process, the waste heat of the recycled material is reduced. Two times of intermittent forced stirring are adopted, the first stirring is that hot new aggregates and heat recovery materials are mixed, asphalt is not added, the asphalt is prevented from making contact with high-temperature new aggregates which do not complete heat exchange and aging is avoided, during the second intermittent forced stirring, heat exchange of the hot new aggregates and the heat recovery materials is completed, the asphalt and mineral powder are added, and the quality of regenerated asphalt concrete products is guaranteed.
本发明提供一种低碳沥砼生产成套装备及沥砼生产工艺，涉及沥青混凝土生产技术领域，低碳沥砼生产成套装备包括双层烘干滚筒和拌合主楼，两者为前后道工艺关系，该发明，利用双层烘干滚筒，使加热后的新骨料和未加热的回收料进入内筒体和外筒体之间的夹层内，以达到利用内筒体散发的余热加热回收料的目的，且回收料从夹层低端进入，高端下料，逆向下料，回收料受热更加充分，回收料与新骨料之间热差比小,在拌合过程中，采用两次间歇强制搅拌，首次搅拌为热新骨料与热回收料拌合，不加入沥青，避免沥青接触到未完成热交换的高温新骨料而老化，在二次间歇强制搅拌时，热新骨料与热回收料已完成热交换，加入沥青和矿粉，保证再生沥砼产品质量。
