VIBRATION MIXER Russian patent published in 2014 - IPC B28C5/16 B01F11/00 

FIELD: machine building.

SUBSTANCE: mixer comprises a mixing chamber, a rotor with blades. In the top and bottom parts of the mixing chamber, lower and upper vibrators are set in the centre and rigidly fixed, they are made in casings and generate vibrations by lower, central and upper crank mechanisms. The vibrators' casings are made as metal shells being corrugated thin-walled bodies of rotation which in the vertical plane section provide for complex truncated geometric figures by corrugation peaks points, the figures are formed by central intersection of four circles with the centres being the vertices of a square and with the radiuses being equal to the diagonal of the said square, and can generate three vibration fields equal in amplitude and different in frequency. A disk is rigidly fixed inside the shell of the lower vibrator in the centre in the horizontal plane, it is fitted with a cylindrical protrusion able of being inserted and fastened along the inner diameter of a spring installed so that it can be freely compressed/released in a cup. A connecting rod driven by the central crank mechanism is rigidly attached to the centre of the cup's upper inner part, and a pusher is attached to the centre of the cup's upper outer part, the pusher is rigidly coupled by the other end with the inner upper part of the metal corrugated shell of the lower vibrator casing. The lower vibrator disk provides for the possibility of generating vibrations of the central part of the lower vibrator casing with the help of four pushers which by their upper part are symmetrically attached to the lower part of the disk and by the lower part are coupled in a movable pivot unit of the connecting rod of the lower crank mechanism. A disk with a guide post is rigidly fixed inside the upper vibrator shell in the centre in the horizontal plane. The stem is rigidly attached to the centre of the cup's inner part, and a pusher is attached to the centre of the cup's outer part, the pusher is rigidly coupled by the other end with the inner part forming the smallest corrugation from those of the upper vibrator's metal corrugated shell, and can generate vibrations from the smallest corrugation out of those of the upper vibrator casing. Four protrusions are symmetrically set on the outer cylindrical part of the cup. 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: qualitative intensification of component mixing process on the whole.
