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 top and bottom encased vibrators are rigidly secured at the center of mixing chamber top and bottom parts to excite three equal-amplitude different-frequency vibration fields by bottom, mid and top crank gears. Cases of vibrators are composed of metallic corrugated shells composed of thin-wall corrugated solids that form truncated circles in vertical plane section over crimp peaks points. Disk 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-rod 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. Bottom vibrator disk excites bottom vibrator case central part by four pushers with their top part symmetrically attached to disk bottom. Their bottom part is fitted into bottom crank gear con-rod moving hinge. Disk with guide post is rigidly secured inside corrugated shell of top vibrator at the center of horizontal plane. Four ledges are secured in symmetry to barrels outer cylindrical surfaces.

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