VIBRATION MIXER Russian patent published in 2017 - IPC B01F11/00 B01F13/10 B01F7/18 

FIELD: machine engineering.

SUBSTANCE: invention relates to devices for mixing multicomponent mixes and can be used primarily in chemical and construction industries, as well as in other areas of manufacturing industries where production of this type of mixes is needed. Vibration mixer comprises a mixing chamber with ports for loading and unloading of materials respectively, a rotor with rotary drive configured with blades. The lower and upper parts of the mixing chamber comprise two rigidly fixed vibrators: lower and upper one made in corrugated casings and generating vibrations by lower, central and upper crank mechanisms, and providing for the vibration field superimposition effect in the mixing chamber center from the lower and the upper vibrators respectively. Inside the metal corrugated casing of the lower vibrator configured for generating two vibration fields identical in amplitude and different in frequency with the help of the lower and the central crank mechanisms, a disc is set in the center in the horizontal plane and is rigidly fixed, the disc is made with cylindrical protrusion configured to be inserted and fastened along the inner diameter of a spring installed to be freely compressed and released in a cup, a connecting rod driven by the central crank mechanism is rigidly attached to the center of the cup's upper inner part, and a pusher is attached to the center of the cup's upper outer part, the pusher is rigidly coupled by its other end with the inner upper part of the metal corrugated casing of the lower vibrator and made fro generating vibrations from the upper part of the lower vibrator casing via the connecting rod by the central crank mechanism. The lower vibrator disc is configured for generating vibrations from central part of the lower vibrator casing with the help of four pushers which are symmetrically attached by their upper part to the lower part of the disc and are coupled by the lower part in a movable pivot unit of the connecting rod of the lower crank mechanism. A disc with a guide post is rigidly fixed inside the shell of the upper vibrator in the center in the horizontal plane, configured to provide stable directed translatory motion of a rod from a sliding pair formed by the guide post of the upper mixing chamber part, the guide post of the blade rotation drive and upper vibrator rod of the upper crank mechanism, and fitted with a cylindrical protrusion to be inserted and fastened along the inner diameter of a spring installed so that it can be freely compressed//released in a cup, a rod is rigidly attached to the inner part center, and a pusher is attached to the outer part center, the pusher is rigidly attached by its other end to the inner part of the smallest of the corrugations, the casing of the upper vibrator and configured with oscillation excitation from the smallest of the corrugations of the upper vibrator casing. There are four protrusions symmetrically secured on the outer cylindrical part of the cup. The casings of the vibrators are made in the form of metal corrugated shells which are corrugated thin-walled rotation bodies forming complex truncated geometric figures in the cross-section of the vertical plane along the corrugations upper points consisting of equal semicircles, which end intersection points form the vertices of the regular hexagon, and configured for creating three vibrational fields of equal amplitude and different frequency, two of which correspond as whole, and the third is saparate, in the form of corrugated contour of said rotation bodies with multidirectional oscillations. A spring vibration generator made as a spring set is installed in the center between the casings of the lower and the upper vibrators, the spring set consists of at least two springs of different diameter which are fixed along the diameters of recesses formed on the outer surface of the metal corrugated shells by the set of the smallest corrugations of the lower and upper vibrators.

EFFECT: technical result consists in extending the range of technical means.
