The work objective is to provide stirred tanks with a swinging movement of impellers, as they differ from the other modern devices in higher intensity and uniform mixing. Synthesis of the actuator diagrams is carried out by the structural mathematical models. As a result, the leverage and gear units with one or two independent closed loop circuits are obtained. Four-bar linkage and a planetary mechanism with elliptical gearwheels under the appropriate dimensioning of the links are converting rotary mode into reciprocating rotation. The application of the gear and continuous drive allows creating a set of structural diagrams which differ in the number of impellers and their location. On the basis of the developed structural schemes, high-efficient stirrers for the chemical, petrochemical and food industries can be worked out and designed. The advantage of the proposed mechanisms is that they are developed from the known, well-established, and highly reliable devices. Besides, the impellers are well configured throughout the total reactor volume creating a rational heat-mass exchange.
