MIXER Russian patent published in 2024 - IPC B01F27/90 B01F27/921 B01F27/922 B01F31/44 

FIELD: various technological processes.

SUBSTANCE: invention relates to devices intended for carrying out various heat and mass exchange processes of chemical technology, in which it is required to create a homogeneous field of concentrations and temperatures in the entire volume of the mixed medium at rational power consumption. Mixer comprises a shaft, a rotor installed coaxially to the shaft with the possibility of reciprocating in the axial direction, radial spokes, to the surfaces of which conical pins with tops directed downwards are attached, and to the outer ends elastic elements are attached, to the rotor there are two coaxially installed spirals with holes, having an opposite direction of turns and a variable pitch, wherein the pitch of the outer spiral increases from the centre to the edges while the pitch of the inner spiral increases from the edges to the centre; the holes in the outer spiral have a circular cross-section, and the holes in the inner spiral have a square cross-section.

EFFECT: high quality of mixing of liquid media.
