【 摘 要 】

References(8)Cited-By(6)Mixing performances of a new mixing equipment which has a vibrating motor with some fin oscillators on a pair of shafts were investigated. This mixing equipment, which is mainly used for industrial plating processes, was usually operated at the vibrating frequency from 30 Hz to 60 Hz with the amplitude from 1 mm to 10 mm.The mixing time and the circulation time were measured and the flow pattern and the mixing process were visualized. The mixing time and the circulation time took the optimum values (the minimum values) for the equipment design at the frequency range from 40 Hz to 50 Hz irrespective to the configuration of the fins. The complete mixing was achieved in three to four circulations of the liquid in the vessel. From the visualization of the flow pattern and the mixing process it was shown that a primary circulation flow passing through the fins was very important for the mixing operation.
