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 three equal-amplitude different-frequency vibration fields by top, mid 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 spring is secured inside bottom vibrator shell. Said spring is fitted in the barrel engaged with crank gear con-rod and pusher. Bottom vibrator disk is provided with four pushers engaged with con-rod of bottom gear. Top vibrator has the disk with spring fitted in barrel engaged with pusher and top vibrator con-rod. The spring is arranged between top and bottom vibrator cases to be contracted/released in barrel. 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. 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. Spring-type vibration excited is arranged at the center between cases of top and bottom vibrators and composed of at least two different-diameter springs.

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