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 vibrators are rigidly fixed in the lower and upper parts of the mixing chamber in center which are made in corrugated bodies with excitation of oscillations by means of lower and upper crank mechanisms, 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. The 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 centers of inner parts 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 body corrugations and made with the function of oscillation excitation from the smallest ones of the vibrator body corrugations. Four protrusions are symmetrically set on the outer cylindrical parts of the cups. Bodies of the vibrators are made in the form of similar metal corrugated shells representing corrugated thin-walled bodies of rotation which form complex truncated geometric figures in section of vertical plane by points of corrugations apexes consisting of equal half-circles in a set which extreme points of intersection form apexes of regular hexagon, and made with the possibility of creation of two vibration fields similar in amplitude and different in frequency, each of which corresponds to the shape of corrugated contour of said bodies of rotation with differently directed 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: extended technical means stock and provided qualitative intensification of mixing process.
