本发明的厂拌沥青冷再生设备采用间歇式搅拌工艺，骨料、粉料、水及沥青等采用单独计量，相比与以往的连续式厂拌冷再生设备，计量精度高，物料级配准确，而且拌和时间可依据需要设定，计量好的物料依次加入搅拌锅内，有效地提高了沥青混合料的均匀性，可满足稳定土路基料、沥青冷再生料的生产，适用范围更广。搅拌主机采用双卧轴强制搅拌结构，搅拌叶片呈特殊角度布置，搅拌均匀，成品料匀质性好。罐体底部设有气动卸料口。配料机及成品料储料仓均配备破拱装置，防止再生料的粘连。配套的水计量系统采用精计量装置，测量准确度高，同时供水可用于清洗沥青供给管路，防止沥青管路堵塞。采用立式沥青罐，对流体状态要求低、压力损失小等特点。The plant-mixed asphalt cold recycling equipment of the present invention adopts intermittent mixing technology, and the aggregate, powder, water and asphalt are measured separately. Compared with the previous continuous plant-mixed cold recycling equipment, the measurement accuracy is high and the material gradation is accurate. , and the mixing time can be set according to the needs, and the measured materials are added to the mixing pot in turn, which effectively improves the uniformity of the asphalt mixture, and can meet the production of stabilized soil road base materials and asphalt cold recycled materials, and has a wider application range. The mixing host adopts a double-shaft forced mixing structure, and the mixing blades are arranged at a special angle, which ensures uniform mixing and good homogeneity of the finished material. There is a pneumatic discharge port at the bottom of the tank. The batching machine and finished material storage silo are equipped with arch breaking devices to prevent the adhesion of recycled materials. The supporting water metering system adopts fine metering device, which has high measurement accuracy, and the water supply can be used to clean the asphalt supply pipeline to prevent the asphalt pipeline from being blocked. The vertical asphalt tank is adopted, which has the characteristics of low fluid state requirements and small pressure loss.
