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

FIELD: construction.

SUBSTANCE: vibration mixer comprises a mixing chamber with windows for charging and discharging materials, a rotor with a rotation drive made with blades. In the upper and lower parts of the mixing chamber in the centre there is an upper and a lower vibrators, made in bodies. Bodies of vibrators are made in the form of identical metal corrugated shells that represent corrugated thin-walled solids of revolution, forming complex truncated geometric figures in the cross section of the vertical plane at the points of the corrugation tops, and the figures are formed with central crossing of four circumferences with centres making tops of the square, and radii equal to the diagonal of this square, and made as capable of creating two vibration fields of identical amplitude and different frequency, each corresponding in shape to the corrugated contour of these solids of revolution, with differently directed oscillations, inside each of which in the centre in the horizontal plane there are discs rigidly fixed with guide stands, the function of which is to develop stable reciprocal movements of stems from a reciprocal pair formed by the guide stand of the lower part of the mixing chamber and the stem of the lower vibrator, the lower crankshaft mechanism and from the reciprocal pair formed by the guide stand of the upper part of the mixing chamber, by the guide stand of the drive of blades rotation and the stem of the upper vibrator, the upper crankshaft mechanism. Discs of the lower and upper vibrators are made with cylindrical protrusions, the function of which is the possibility to insert and fix springs at the internal diameter, which are installed with the function of free compression/release in sleeves, to the centres of the internal parts of which there are stems rigidly fixed, to the centre of the external parts - pushers, which are rigidly fixed by the other end to internal parts that form smallest corrugations, metal corrugated shells, and made with the function of excitation of oscillations from the least corrugations of vibrator bodies. Four protrusions are symmetrically fixed at external cylindrical parts of each sleeve. Between the bodies of the lower and upper vibrators in the centre there is a spring vibration exciter made in the form of a spring group made of at least two springs with different diameter, which are fixed along diameters of indents formed on the outer surface of the metal corrugated shells with a group of smallest corrugations of the lower and upper vibrators.

EFFECT: complete prevention of dead zones in a mixing chamber and high-quality intensification of a process of components mixing.
