Stable arch can not be formed with rotation bulkhead on the inside of rotation bulkhead, so the basis blocked is disintegrated, then arch caves in
Block and eliminate, and then ensure that the coal dust material in whole rotating cabin body is in overall flow state, so as to solve run coal bin chute blockage
Problem.Rotate bulkhead operationally, change coal dust material flow regime in rotating cabin body so that flowed and flowed with center originally
Be changed into for the flow regime of the main type of flow based on overall flow, this makes it possible to reduce coal dust material in bulkhead near
The flow dead of appearance, so as to reduce the chute blockage probability at fore shaft position.It is provided with movable warehouse upper end and is used to prevent fine coal from falling
Enter to support bulkhead and rotate the fine coal barrier structure of annular space between bulkhead, prevent coal dust from being had an impact to movable warehouse structure；Cause
This, the utility model can make coal dust material be in overall flow state, so as to solve the problems, such as run coal bin chute blockage.
