MIXER FOR TANKS WITH SMALL NECK Russian patent published in 2014 - IPC B01F7/18 B01F7/24 

FIELD: mechanical engineering.

SUBSTANCE: mixer comprises a rotary drive, a shaft with blades arranged inside the fixed tubular element, rigidly coupled with a rotary drive housing. A cylindrical and conical nozzle with a circular mouthpiece is installed with gap on the tubular element in its lower part, inside the cylindrical part of the mouthpiece there are helical blades on the shaft, and in the conical part of the mouthpiece - longitudinal guiding ribs, besides the length of the cylindrical part of the mouthpiece is at least four of its internal diameters, and the length of the conical part of the mouthpiece is at least three inner diameters of the cylindrical part of the mouthpiece. An area of internal section of the nozzle is equal to half of the area of internal section of the cylindrical part of the mouthpiece.

EFFECT: efficient mixing of multicomponent disperse systems of different viscosity in containers with a neck of small size and with different degree of intensity without foaming.
