回转切换定位吹吹清灰装置是针对劳扬扁袋除尘器开发的，但也同样适用于各种分室结构装式除尘器。本项装置利用回转反吹的机理，设计一种独特的电动回转切换网和林轮传动步进机构，对各室实现定位脉冲（5～10秒）喷吹，回转切换间旋转一周，对各室依次清灰一次，用一阀代替多阀 Rotary switch positioning blow blowing cleaning device is developed for flat bag filter Launching, but also applies to a variety of sub-chamber structure mounted dust collector. This device utilizes the mechanism of rotary backflushing to design a unique electric rotary switch network and a step-by-step mechanism of a forest wheel drive. The positioning pulse (5-10 seconds) is injected into each chamber and the rotary switch is rotated for one week. Room followed by cleaning, with a valve instead of multiple valves
