摘　　要：为解决ZL29型滤棒成型机组滤棒加速器中因负压腔内粉尘堆积而造成加速轮吸风孔处吸风不稳定等问题,对滤棒加速器进行了改进。利用Ansys仿真软件对负压腔内的气流分布进行分析,得到负压腔内气流死角位置;通过增加正压气流对处于气流死角的粉尘施加作用力,使粉尘持续保持运动状态并随气流排出负压腔。以贵阳卷烟厂使用的2台ZL29机组为对象进行测试,结果表明:改进后滤棒加速器拆卸清理次数由15次/月降低到4次/月,维保时间由610 min/月减少到160 min/月,有效提高了滤棒加速器工作稳定性,改善了粉尘堆积情况。该方法可为提高ZL29机组运行效率提供支持。To minimize the variation of suction at the suction holes of accelerating wheel caused by dust buildup in the vacuum chamber of the filter rod accelerator in ZL29 filter rod maker,the accelerator was modified.The airflow distribution in the vacuum chamber was analyzed with Ansys simulation software to determine the location of dead corner.A stream of airflow was introduced to force the dust at the dead corner to leave the vacuum chamber together with the airflow.The modified accelerator was tested on 2 ZL29 filter rod makers in Guiyang Cigarette Factory.The results showed that the maintenance frequency of filter rod accelerator reduced from 15 to 4 times per month,the monthly maintenance time decreased from 620 to 160 min,and the running stability of filter rod accelerator was improved effectively.This method provides a support for promoting the efficiency of ZL29 filter rod maker.
