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 vibrator excites equal-amplitude different-frequency vibration fields by top and bottom crank gears. 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 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. Said disk uniformly distributes vibration field from the case top to bottom by creation of uniform amplitude displacements of every point of corrugated shell pouter generatrix and excited vibrations by means of four pushers with their top part secured in symmetry to disk bottom and bottom part fitted in top crank gear assy con-rod hinge.EFFECT: ruled out dead zones in mixing chamber, intensified mixing of components.2 dwg |
