VIBRATION MIXER Russian patent published in 2015 - IPC B01F11/00 B28C5/00 

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. Top and bottom vibrators are rigidly secured at the centre of mixing chamber top and bottom parts. top and bottom vibrators fitted in corrugated cases are excited by bottom, mid and top rank gears. 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 is rigidly secured to the barrel inner top centre and driven by top crank gear while pusher is secured to outer top, pusher other end being secured to inner top part of said metal corrugated shell. Said disc can excite vibrations from vibrator casing central part by four pushers with their top part symmetrically secured to disc bottom part and their bottom part articulated with crank mechanism con-rod moving swivel. Top vibrator case inside accommodates disc with guide prop rigidly secured at horizontal plane centre. Said disc allows fitting and securing of the spring over its ID fitted in the barrel. Four ledges are secured in symmetry to barrel outer cylindrical surfaces. Vibrator case is composed of metallic corrugated shells. Said shells are composed of corrugated thin-wall solids of revolution making the truncated equilateral triangles in vertical plane cross-section over crimp top points. Spring vibration exciter is arranged at the centre between said top and bottom vibrators. Said excited is composed by set of springs consisting of at least two different-diameter springs. Said springs are secured over diameters of recesses made at shells outer surfaces as the set of the smallest crimps of top and bottom vibrators.

EFFECT: creation of three different-frequency vibrating fields, complying with corrugated body shape, two of which together and one separately, over the mixer entire volume to be plied to mix components.
