STIRRER Russian patent published in 2021 - IPC B01F7/16 

FIELD: engineering.

SUBSTANCE: invention relates to capacitive-type apparatuses intended for conducting various heat and mass transfer processes of chemical technology requiring to create a homogeneous concentration and temperature field throughout the entire volume of the stirred medium, and can be used in the chemical, food, construction and other branches of industry. The stirrer consists of a vertical shaft, a rotor with radial spokes, attached at the ends whereof are confusers with inlet expanding holes oriented in the direction of rotation, wherein the confusers are installed on the spokes in pairs coaxially relative to each other and are interconnected by longitudinal ribs. The vertical shaft therein has a thread in one direction for half of the length thereof, and in the opposite direction for the other half of the length, wherein rotors with 2 to 5 radial spokes installed thereon are mounted by the threads thereof on each thread, configured to rotate in different directions from each other. The vertical shaft is also rigidly fixed on a bevel gear engaging with another bevel gear fixed on the shaft of the reducer rotated by the shaft of a horizontally located reversible engine.

EFFECT: increased homogeneity of the composition of the mixed liquids, reduced mixing time and increased labour efficiency.
