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. Vibrators are rigidly secured at the center of mixing chamber top and bottom parts. Said encased bottom and top vibrators excite two equal-amplitude different-frequency vibration fields by top and bottom crank gears. Cases of vibrators are composed of metallic corrugated shells composed of thin-wall corrugated solids that form truncated circles and semi-ellipse in vertical plane section over crimp peaks points to excite opposite direction vibrations. At the center of every said shell disks with guide posts are rigidly secured to make con-rods translate driven by translation pairs composed of mixing chamber bottom guide post and bottom vibrator con-rod, bottom crank gear, mixing chamber top guide post, vane drive guide post and top vibrator rod of top crank gear. 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 secured at the center between top and bottom vibrators over diameter of recesses formed by the smallest crimps of corrugated shells of said vibrators.

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