METHOD FOR CONTROLLING A RESONANT-WAVE MIXER AND A DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2022 - IPC B01F31/00 

FIELD: mixing devices.

SUBSTANCE: inventions group relates to a method for controlling a resonant-wave mixer and a device for its implementation, in particular, to a device for mixing components of various aggregate states to obtain homogeneous multi-component (including high-viscosity) mixtures for various purposes and to a control system for the process of their mixing by forming a resonant-wave effect and algorithm for stabilizing the amplitude of mixture oscillations. The resonant-wave mixer consists of bases, between which at least one rack is installed and a platform with a working table is located, at least two elastic elements are installed between the platform and the bases, while the platform is made with the ability to perceive movement from at least one engine, which is configured to receive control commands from at least one control element, according to the claimed solution, the engine is configured to transmit linear movement to the platform in a direction perpendicular to the platform plane, and the control element is configured to set the engine movements in the direction of platform movement. The method for controlling a resonant-wave mixer consists in the formation of a force that excites oscillations of a container with mixed materials or material, while the effects of the force are subject to a periodic function, the phase of which is set relative to one of the parameters of the system movement, according to the claimed solution, the phase of the exciting force is set to coincide with the phase of the movement speed system, and the amplitude of the exciting force is set using a closed system that stabilizes the amplitude values of one of the parameters of the system motion.

EFFECT: expansion of the mixer performance due to improved provision of undamped self-oscillations of the mixer capacity at the resonant frequency of the mixed materials or material with more flexible and accurate control of such mixing parameters as displacement amplitude, maximum speed and maximum acceleration, while reducing power consumption and the required amount of time per one operation.
