塑化机料筒单边加热会导致物料加热不均、径向温差大、效率低等问题,提出了一种基于三相感应电机原理的塑化机双边电磁感应加热技术;设计了样机,仿真计算了料筒和螺杆的涡流分布;分析了系统结构参数对加热性能的影响,并对样机进行了温升试验,通过对比发现设备径向温差明显减小,预热时间大大缩短。 The unilateral heating of the plasticizer barrel will result in the problems of uneven heating, large radial temperature difference and low efficiency. Based on the principle of three-phase induction motor, a double-sided electromagnetic induction heating technique is proposed. Prototype and simulation The eddy current distribution of the barrel and the screw was calculated. The influence of the structural parameters of the system on the heating performance was analyzed. The temperature rise test was carried out on the prototype. The radial temperature difference of the equipment was obviously reduced and the preheating time was greatly shortened.
