VIBRATION MIXER Russian patent published in 2014 - IPC B01F11/02 

FIELD: construction.

SUBSTANCE: vibration mixer comprises a mixing chamber with windows of materials loading and unloading, a rotor with a rotation drive made with blades. In the lower and upper parts of the mixing chamber in the centre there are two: lower and upper vibrators, made in bodies with excitation of oscillations by means of lower and upper crank-and-rod mechanisms, accordingly, and with a function of development of effect of superimposition of vibration fields in the centre of the mixing chamber from the lower and upper vibrators. Bodies of vibrators are made in the form of identical metal corrugated shells, which represent corrugated thin-walled solids of revolution and made as capable of developing two vibration fields that are identical in amplitude and different in frequency, each corresponding in shape to a corrugated contour of these solids of revolution, with differently directed oscillations. Inside each shell in the centre in the horizontal plane there are discs fixed rigidly with guide stands, the function of which is to create stable directed reciprocal movements of stems from reciprocal pairs. Discs of lower and upper vibrators are made with cylindrical protrusions, the function of which is to insert and fix springs along the inner diameter, and springs are installed with a function of free compression/release in sleeves, to the centres of inner parts of which there are stems fixed rigidly, to the centre of outer parts there are pushers fixed, which are rigidly fixed by the other end to inner parts, forming least of corrugations of metal corrugated shells, and made with a function of excitation of oscillations from least of corrugations of the vibrator bodies. At the same time at the external cylindrical parts of the sleeves there are four ledges fixed symmetrically on each one, and their function is to transfer reciprocal movements to discs, made as capable of homogeneous distribution of vibration fields from least of corrugations of metal corrugated shells to areas of fixation of bodies by means of creation of homogeneous amplitude values of movements of each point of external forming metal corrugated shells at the moment of compression of springs until stop at rubber gaskets, made with a function of softening of ledges collision with discs.

EFFECT: expanded arsenal of technical facilities, increased intensity of a process of mixture components mixing, increased efficiency of a vibration mixer.
