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

Abstract RU 2673281 C2

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 mounted 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 lower vibrator body made with the function of excitation of two vibration fields similar in amplitude and different in frequency by the means of the lower and center crank mechanisms, there is a disc with a cylindrical protrusion rigidly fixed in the center in the horizontal plane configured to enable inserting and fixing spring along the inner diameter installed with a function of free compression/extension in cup, which upper inner part center is rigidly fixed to the connection rod with the center crank mechanism drive, and which upper outer part center is rigidly fixed to the pusher rigidly connected to the inner upper part of the lower vibrator body with the other end and configured with the function of oscillation excitation from the upper part of the lower vibrator body through the connection rod by center crank mechanism. Disk of the lower vibrator is configured with the possibility of oscillations excitation of central part of lower vibrator body with four pushers which upper part is symmetrically fixed to the lower part of the disk, and which lower part is connected to the unit of the connection rod movable joint of the lower crank mechanism. Disc with a guide post is rigidly fixed inside the upper vibrator body in the center in the horizontal plane which function is to create stable directed translational motions of the rod from the prismatic pair formed by the guide post of the upper part of the mixing chamber, guide post of the blades rotation drive and the rod of the upper vibrator, the upper crank mechanism and a cylindrical protrusion configured to enable inserting and fixing spring along the inner diameter installed with a function of free compression/extension in cup which inner part center is rigidly fixed to the rod, and outer part center is rigidly fixed to the pusher rigidly connected with the other end to inner part which forms the smallest one of the corrugations, upper vibrator body, and configured with the function of oscillation excitation from the smallest of upper vibrator body corrugation. Four protrusions are symmetrically fixed along the outer cylindrical parts of the cups. 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 heptagon, and configured for creating three vibrational fields of equal amplitude and different frequency, two of which correspond as whole, and the third is separate, 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.
