Objective:Aiming at the problem that the hot air filter is a closed and rotating equipment part of the SJ1513 type stem feeder,after continuous production,the inner wall of the filter can not be cleaned during the daily maintenance,which makes the screen clogged,so that the hot airvolume decreases,hot air circUlation slows down,causing the material process parameters not up to standard,and equipment operating parameters fluctuating,automatic shutdown and other probiems,Method:According to the filter structure,the cleaning nozzle is made and installed in the confined space,and the pipe is used to connect the nozzle and the water and steam mixer.The steam and water are adjusted to water of 60 ℃C by water and steam mixer,and electrical control to achieve automatic cleaning filter wall.Result:After the cleaning device is developed and installed,the proportion of automatic shut-down failure caused by low hot air temperature due to filter clogging is reduced to 0 from 80％,the production stage equipment hot air temperature fluctuation range is 54 ℃-57 ℃ (process requirement:55 ± 5 ℃),the number of material sampling not up to standard is 0;Conclusion:The improved scheme proposed in this paper has certain reference value for the automatic cleaning inside the closed and rotattng cylindrical equipment parts.%目的:针对热风滤网是SJ1513型梗丝加料机上一个密闭、旋转的设备部件,在连续生产后,滤网内壁污垢堆积,日常保养时滤网内壁无法清洗,造成滤网堵塞,使热风风量减小、热风循环慢,引起物料工艺参数不迭标、设备运行参数波动大、自动停机等问题;方法:根据滤网结构,制作并在密闭空间内安装清洗喷管,使用管道将喷管与水、汽混合器连接,将蒸汽及水通过水、汽混合器调节成60℃的热水,利用电磁阀及电气控制实现滤网内壁的自动清洗;结果:在清洗装置研制并安装使用巩固期内,因滤网堵塞造成热风温度过低设备自动停机的故障,从占设备故障率的.80％下降为0,生产阶段设备热风温度波动范围54℃-57℃(工艺要求为55±5℃),物料抽检不达标次数为0次;结论:本论文提出的改善方案,对密闭、旋转的圆筒形设备部件内部的自动清洗具有一定的参考价值.
