VIBRATION MIXER Russian patent published in 2013 - IPC B28C5/16 B01F11/00 

FIELD: process engineering.

SUBSTANCE: invention relates to concrete mixers and may be used in other fields of construction. Said mixer comprises mixing chamber with material loading and discharge openings, vaned rotor, rotor drive, encased vibrator rigidly secured at mixing chamber center and equipped with vibration exciter composed of crank gear. Vibrator casing is composed of metal shell representing a corrugated thin-wall solid of revolution making a complex truncated geometrical figure in vertical plane cross-section formed by central intersection of three circles with centers making the regular triangle vertices and radii equal to height of said triangles. It allows generating opposite direction oscillations. Disc is secured at the said figure center in horizontal plane to create rod translation from translation pair composed of mixing chamber bottom post guide and crank mechanism rod and cylindrical ledge to be fitted and secured at spring ID, said spring being set to be contracted/released in the barrel, while said rod is rigidly secured at inner part top center. Pusher is attached to outer parts centers, opposite ends of said pushers being rigidly secured to inner parts forming smallest crimps of corrugated shells. Four ledges are secured in symmetry to barrel outer cylindrical surfaces.

EFFECT: ruled out dead zones in mixing chamber, intensified mixing of components.
