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, rotor drive, encased vibrator rigidly secured at mixing chamber center. Said encased bottom and top vibrators excite three equal-amplitude different-frequency vibration fields by top and bottom crank gears. Cases of vibrators are composed of metallic corrugated shells that form semi-ellipses and truncated circles in vertical plane section over crimp peaks points to generate different-direction oscillations. 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 secured to top outer part of said disk, its opposite end being rigidly secured to corrugated shell inner top part to excite vibrations from vibrator top part via con-rod driven by top crank gear or some other gear. Disc can excite oscillations from vibrator central part with the help of four pushers. Top part of said pushers are secured in symmetry to disc bottom part. Their bottom part is fitted into bottom crank gear con-rod moving hinge.

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