VIBRATION MIXER Russian patent published in 2013 - IPC B28C5/16 B01F11/00 

FIELD: process engineering.

SUBSTANCE: invention relates to concrete mixers and may be used in other fields of construction. Said mixer comprises mixing chamber with material loading and discharge openings, vaned rotor and rotary drive. Top and bottom vibrators are rigidly secured at the center of mixing chamber top and bottom parts. bottom and top vibrators to excite two equal-amplitude different-frequency vibration fields by top and bottom 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. 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-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.
