针对悬臂式斗轮机恒速回转取料时存在取料不均、取料效率低和自动化程度不高等缺点,以及角度余弦开环控制方式不能处理料堆塌方等突发情况,提出了视频流量闭环控制方式.该控制方式通过实时检测取料瞬时流量,自动控制斗轮机悬臂的回转速度进行取料.对比研究及运行结果表明,该方式提高了取料效率,达到了节能增效的日的.%Aiming at the demerits of the constant speed cantilever bucket wheel reclaimer, e.g., uneven reclaiming, low efficiency and the automation level is not high enough, as well as the open-loop control system based on angle of cosine is unable to handle emergencies such as landslip of material piles, thus the VF flow closed-loop control scheme is proposed.With this control scheme, through detecting reclaiming simultaneous flow in real time, the rotating speed of the cantilever is controlled automatically for reclaim.The research of inter-comparison on operation results indicates that this method enhances reclaim efficiency to reach the purpose of energy saving.
