VIBRATION MIXER Russian patent published in 2018 - IPC B01F11/00 B01F13/10 B01F7/18 

FIELD: machine engineering.

SUBSTANCE: vibration mixer comprises a mixing chamber with the ports for loading and unloading materials respectively, a rotor with blades and rotary drive. The lower and upper parts of mixing chambers comprise two vibrators rigidly mounted in the center: the lower and upper ones are made in corrugated casings with the generation of vibrations by lower and upper crank mechanisms respectively, and with a function of creating vibration field superimposition effect in the center of mixing chamber from the lower and the upper vibrators respectively. Inside each of the housings there are discs with guide stands centered horizontally and rigidly fixed, which function is to provide stable aimed translational rods motion from the prismatic pair formed by the guide stand of the mixing chamber bottom and the lower vibrator, lower crank mechanism rod, and from the prismatic pair formed by the guide stand of the mixing chamber top, the guide stand of the blade rotation drive and the upper vibrator, upper crank mechanism rod, respectively. Discs of the lower and upper vibrators are made with cylindrical projections which function is to enable inserting and fixing springs along the inner diameter installed with a function of free compression/extension in cups, which inner parts center are rigidly fixed to the rods, outer parts center are rigidly fixed to the pushers rigidly connected to the inner parts with the other end, which form the smallest ones of the bodies corrugations. Four protrusions are symmetrically set on the outer cylindrical parts of the cups. The casings of the vibrators are made in the form of similar 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 heptagon, and configured for creating two vibrational fields of equal amplitude and different frequency, each of which correspond in the form of corrugated contour of said rotation bodies with multidirectional oscillations. A spring is installed between the casings of the lower and upper vibrators along the diameters of recesses formed by the smallest corrugations from those of the metal corrugated shells at the lower and upper vibrator casings.

EFFECT: expanded range of operating means and provided high quality intensification of the mixing process.
