Classified collection device for asphalt concrete

The invention relates to the technical field of asphalt concrete, in particular to a classified collection device for asphalt concrete. The device is characterized in that a ventilation hole, an extrusion roller separation structure, a storage barrel, a control valve, a second motor, a conveyor belt mechanism, a heating module, a filter plate and an asphalt chamber are sequentially arranged in a box body from top to bottom, the ventilation hole is connected to the control valve through an air pipe, and the control valve is connected to a liquid nitrogen bottle arranged in the box body. According to the device, large aggregates can be rapidly and cleanly stripped from asphalt, the recovery rate of the asphalt concrete is high, the resources are saved, and the environment is protected. 本发明涉及沥青混凝土技术领域，具体是一种沥青混凝土分类收集装置，所述箱体内从上至下依次安装有通风孔、挤压辊分离结构、存料筒、控制阀、第二电机，传送带机构、加热模块、滤板、沥青室，所述通风孔通过气管连接有控制阀，所述控制阀连接有设置在箱体内的液氮瓶；该装置快速将大块集料干净的从沥青中剥离出，对沥青混凝土的回收率高，节约资源，保护环境。
