VIBRATION MIXER Russian patent published in 2015 - IPC B01F11/00 B28C5/00 

FIELD: construction.

SUBSTANCE: vibration mixer comprises a mixing chamber with the ports for loading and unloading of materials respectively, a rotor with blades and rotary drive. In the top and bottom parts of the mixing chamber, two vibrators are set in the centre and rigidly fixed: the lower and upper vibrators are made in corrugated casings and generate vibrations by lower and upper crank mechanisms respectively. Disks with guide posts are rigidly fixed inside each housing and are set in the centre in the horizontal plane. The disks of the lower and upper vibrators are provided with cylindrical protrusions installed in cups, connecting rods are rigidly attached to the centres of the cups' inner parts, and pushers are attached to the centre of the cups' outer parts, the pushers are rigidly coupled by the other end with the inner parts of the metal corrugated shells forming the smallest housing corrugations. Also four protrusions are symmetrically fixed on the outer cylindrical parts of the cups. The vibrators' casings are made as identical metal corrugated shells being corrugated thin-walled bodies of rotation which in the vertical plane of their sections form the truncated isosceles triangles by corrugation peaks points. A spring vibration generator made as a spring set is installed in the centre 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 from those of the lower and upper vibrators.

EFFECT: invention allows to create in all over the volume of the mixer chamber for the mixed components of concrete mix two vibration fields with different frequency.
