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

FIELD: construction.

SUBSTANCE: invention relates to devices for mixing of a concrete mix and may be used in construction industry for production of multi-component mixes. The vibration mixer comprises a mixing chamber with windows for materials loading and unloading, a rotor with blades. In the lower and upper parts of the mixing chamber in the centre there are two, lower and upper, vibrators are rigidly fixed, being made in the bodies, with excitation of oscillations by means of lower and upper crank mechanisms, accordingly. Bodies of vibrators are made in the form of identical metal corrugated shells. Inside each shell in the centre in the horizontal plane there are discs rigidly fixed with guide stands. Discs of the lower and upper vibrators are made with cylindrical ledges, the function of which is the possibility to insert and fix springs along the outer diameter, installed with the function of free compression/decompression in sleeves, to the centres of inner parts of which there are stems fixed rigidly, to the centre of outer parts - pushers, rigidly fixed by the other end to the inner parts, forming the smallest from corrugations, metal corrugated shells. Along outer cylindrical parts of sleeves there are four ledges fixed symmetrically on each one, the function of which is to transfer reciprocal movements to discs. Between the bodies of the lower and upper vibrators in the centre there is a spring vibration exciter in the form of a spring group comprising at least two springs of different diameter, which are fixed at diameters of grooves formed on the outer surface of metal corrugated shells with a group of smallest corrugations of lower and upper vibrators.

EFFECT: intensification of a process of mixing of components as a whole.
