VIBRATION MIXER Russian patent published in 2014 - 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. 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 truncated circles in vertical plane section over crimp peaks points. Disk with cylindrical ledge is secured inside shell, at the centre 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 centre. Pusher is attached to outer parts centres, opposite ends of said pushers being rigidly secured to inner parts forming smallest crimps of corrugated shells. Disc can excite oscillations from vibrator central part with the help of four pushers. Vibrator top part is secured to disc bottom part while its bottom part is articulated with lower crank mechanism con-rod hinged assy. Top vibrator shell horizontal plane centre accommodates disc with guide post rigidly secured thereat to allow stable directed translation of con-rod from translation pair composed by mixing chamber top guide post, blade drive guide post and top vibrator con-rod, top crank mechanism and cylindrical ledge. The latter can be fitted in and secured in spring ID, spring being clamped/released in the barrel. Con-rod is rigidly secured to inner part centre while pusher is secured to outer part centre. Pusher opposite end is rigidly secured to inner part that forms the smallest crimp of top vibrator shell to excite vibration of said smallest crimp of top vibrator. Four ledges are secured in symmetry to barrel outer cylindrical surfaces. Spring vibration exciter is arranged at the centre between said top and bottom vibrators. Said exciter consists of at least two different-diameter springs secured to recesses made at outer surface of shells by the smallest crimps of top and bottom vibrators.

EFFECT: intensified mixing.
