Powder feeding system of continuous asphalt mixture stirring equipment and control method
The invention provides a powder feeding system of continuous asphalt mixture stirring equipment and a control method. The powder feeding system is provided with a powder tank, a transition scale, a screw scale, an elevator screw and an aggregate elevator; the control method comprises the follwoing steps : the weight range of the transition weighing powder is determined, and an arch breaking electric valve is started to automatically break an arch according to the weight interval and the real-time weight of the transition weighing powder to supply powder; the transition weigher starts a screw of the transition weigher in a delayed mode according to the delay time, the rotating speed of the screw of the transition weigher is adjusted according to the real-time flow of the screw weigher, andpowder in the transition weigher is quantitatively conveyed to the screw weigher; then the powder in the spiral scale spirally enters the aggregate elevator through the elevator, is mixed with aggregate in the aggregate elevator and then enters the stirring cylinder. The powder control precision can be improved, the stability of the feeding system is high, and waste materials can be reduced.
本发明提供的连续式沥青混合料搅拌设备的粉料给料系统及控制方法，通过设置粉罐、过渡称、螺旋秤、提升机螺旋和骨料提升机；确定过渡称粉料的重量区间，并根据所述重量区间和所述过渡称粉料的实时重量启动破拱电动阀自动破拱，进行补粉；所述过渡称根据延时时间延时启动过渡称螺旋，并根据所述螺旋秤的实时流量调节所述过渡称螺旋的转速，将所述过渡称中的粉料定量输送至螺旋秤；所述螺旋秤中的粉料通过提升机螺旋进入骨料提升机，并与所述骨料提升机内的骨料混合后进入搅拌缸，不仅能够提高粉料控制的精度，而且给料系统的稳定性高，且能减少废料的产生。
