Development and research of vibromixing reactor with rotationally reciprocating motion of impeller

Stirred tanks are widely used in many industries for manufacture of solutions, emulsions and suspensions. Traditional rotational mixers do not allow to achieve the required heat and mass transfer, so many papers are devoted to the creation and research of devices that provide vibrational effect on the stirred product. Rotationally reciprocating stirred tanks are more manufactured in comparison with reciprocating stirrers, since they use standard bearing units and seals. As an actuator of vibromixer it is proposed to use a planetary mechanism with elliptical gearwheels, which converts the rotational motion of the motor into reciprocating rotational motion of impeller. Dynamic model of the stirred tank is constructed by reduction of the forces, masses and moments to primary link (an actuator input shaft). Analysis of the dynamic model was carried out by energy-mass method; as a result, we found the law of motion of the input shaft and the moment of inertia of the flywheel.
