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 con-tinuous 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.

Перемешивание является одним из наиболее распространенных процессов химической технологии и широко применяется в различных отраслях промышленности для интенсификации тепломассообмена [1]. Современные перемешивающие устройства можно разделить на три типа: классические вращательные аппараты, аппараты со сложным пространственным движением рабочих органов, вибрационные перемешивающие устройства.
Следует отметить, что классические вращательные перемешивающие устройства (наиболее распространенные и исследованные [2, 3]) не всегда позволяют эффективно достичь требуемого тепломассообмена.
Более современные аппараты с планетарным [4, 5] и сложным пространственным движением рабочих органов [6, 7] позволяют обеспечить высокую интенсивность тепломассообменных процессов, однако такие устройства не получили широкого распространения в промышленности. Это обусловлено прежде всего сложностью их конструкции, что приводит к затруднениям как на стадиях расчета и проектирования, так и на стадиях изготовления и эксплуатации.
