磨煤机入口热风隔离挡板改造

Improvement of the Hot Air Baffle at the Inlet of Pulverizer

针对磨煤机入口热风隔离挡板经常卡涩及漏热风等故障,提出用悬吊式插板门替换支撑式插板门方案,并从结构上分析了悬吊式插板门的特点和优点。热风隔离挡板更换后,开关灵活,关闭严密,改造效果显著。

The reasons of the troubles,such as frequent jamming and hot air leakage of the air baffle at the inlet of the pulverizer,have been analyzed.The scheme of suspended plug-in shutter instead of support plug-in shutter has been put forward and the features and advantages of the suspended plug-in shutter have been analyzed based on its structure.The improved result is obvious with flexible switch and tight closure after changing of hot air baffle.
