Variable-yield drying roller optimization design method taking material raising time as evaluation

The invention provides a variable-yield drying drum optimization design method taking material lifting time as evaluation, which is suitable for a primary drying drum of an asphalt stirring primary regeneration all-in-one machine, and the primary drying drum comprises a drying drum, a combustor, a drum controller, a frequency converter and a signal detection system; by applying the method, the total scattering time in the unit time can be obtained by counting the scattering time of the sampled particles in the unit time and the number of the particles scattered in the unit time, and then a better internal structure of the variable-yield drying roller can be obtained by analyzing data. 本发明提供了一种以扬料时间为评价的变产量干燥滚筒优化设计方法，适用于沥青搅拌原再生一体机的原生干燥滚筒上，所述原生干燥滚筒包括干燥滚筒、燃烧器、滚筒控制器、变频器及信号检测系统；应用本技术方案可实现通过统计取样颗粒在单位时间内的抛撒时间以及单位时间内抛撒的颗粒数目从而得出单位时间内的总抛撒时间，进而对数据进行分析可得到较优的变产量干燥滚筒内部结构。
