Spiral stirrer unsupported at one end |
摘要 |
A spiral stirrer unsupported at one end, for mixing and stirring free-flowing solids, especially in continuous gas phase polymerization. The stirrer comprises a plurality of turns formed from hollow profiles. The botton end of the spiral, facing the bottom of the stirred vessel, is attached to a hub seated on a drive shaft. In the vicinity of the transition from the hub to the first turn of the spiral, a distributor spiral is provided to avoid flowless zones in the hub region. Uniform distribution of the gas entering at the bottom of the vessel is also achieved.
