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

FIELD: process engineering.

SUBSTANCE: invention relates to continuous-operation vibration mixers to be used in production of construction materials and construction for fabrication of polydisperse multicomponent materials. Said mixer comprises mixing chamber with material loading and discharge openings, vaned rotor and vaned rotor drive. Two vibrators are rigidly secured at the center of mixing chamber top and bottom parts: encased top and bottom vibrators to excite three equal-amplitude different-frequency vibration fields by bottom and top crank gears. Vibrator case is composed of metallic corrugated shell. Said shell is composed of thin-wall corrugated solid of revolution that forms truncated ellipse in vertical plane section over crimp peaks points. It allows generating opposite direction oscillations. Disk with guide post is secured inside shell, at the center of horizontal plane. 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. Four ledges are secured in symmetry to barrels outer cylindrical surfaces. Spring is arranged between cases of top and bottom vibrators, at the center to excite additional vibrations of mixed components from cases of said vibrators.

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