MIXING DEVICE WITH INTERMITTENT MOVEMENT OF WORKING MEMBER Russian patent published in 2020 - IPC B01F7/30 

FIELD: chemistry; construction.

SUBSTANCE: invention relates to mixing devices and can be used in chemical, construction and food industry as a device required for intensification of heat-mass-exchange processes, for levelling concentrations and temperatures in the entire volume of the liquid medium. Intermittent device with discontinuous movement of working member comprises a reactor, a motor, a cover, an actuator housing in which input and output shafts are coaxially installed, central fixed gear wheel rigidly fixed on housing coaxially to input shaft, satellite consisting of cylindrical gear wheel and an elliptical gear wheel of a pinion located on a satellite shaft, a carrier mounted on the input shaft and connected through a rotational kinematic pair to the satellite shaft, an elliptical gear wheel fixed on the output shaft, wherein the elliptical gear wheels have the same dimensions and are mounted on the shafts such that the axis of rotation of each shaft passes through the elliptic gear wheel ellipse centre, besides, central fixed gear wheel with radius r₁ = a, consists in engagement with cylindrical gear wheel of satellite with radius r₂ = b, where a and b are large and small semi-axes of elliptical wheels; working element rigidly fixed on output shaft.

EFFECT: technical result of the invention is compactness of the device while maintaining the possibility of transmitting large forces, considerable expected resource of operation, simplified dynamic balancing.
