DEVELOPMENT OF VIBRATORY MIXER USING NON-LINEAR RESONANCE OF MAGNETICALLY LEVITATED FIN

为了提高液-液或液-粉的混合效率，研制了利用一对永磁体的磁斥力来悬浮翅片的振动混合器。悬浮翅片在圆柱形搅拌槽内受周期性波动的外部磁力激励，进行往复运动。作用在浮片上的恢复力具有很强的非线性。该混合系统有效地利用了翅片的非线性共振。通过实验和数值模拟验证了所研制的振动混合器的有效性。

In order to improve the mixing efficiency for liquid-liquid or liquid-powder, vibratory mixer using levitated fin by magnetically repulsive force of a pair of permanent magnet is developed. The levitated fin is excited by the outside magnetic force fluctuating periodically and performs reciprocating motion in cylindrical mixing tank. The restoring force acted on the levitated fin has strong non-linearity. This mixing system effectively utilizes a non-linear resonance of the fin. Effectiveness of the developed vibratory mixer was confirmed through the experiments and the numerical simulations.
