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 and rotary drive. Top and bottom vibrators are rigidly secured at the center of mixing chamber top and bottom parts. Said encased bottom and top vibrators excite three equal-amplitude different-frequency vibration fields by top, mid and bottom crank gears. 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. Disks with cylindrical ledge is secured inside shell, at the center of horizontal plane, to be fitted and secured over spring ID, spring being arranged inside the barrel to contract/release therein. Con-rods driven by top crank gear is rigidly secured to disk inner top part 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 to be excited by said pusher. Said disc can excite vibrations from vibrator casing central part by four pushers with their top part symmetrically secured to disc bottom part and their bottom part articulated with crank mechanism con-rod moving swivel. Disks with cylindrical ledge is secured inside shell of top vibrator, at the center of horizontal plane, to be fitted and secured over spring ID, spring being arranged inside the barrel to contract/release therein. Con-rods driven by top crank gear is rigidly secured to disk inner top part 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 to be excited by said pusher. Four ledges are secured in symmetry to barrel outer cylindrical surfaces.

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