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

Abstract RU 2519234 C1

FIELD: machine building.

SUBSTANCE: vibration mixer comprises a mixing chamber, a rotor with blades. In the top and bottom parts of the mixing chamber, two vibrators: lower one and upper one, are set in the centre and rigidly fixed, they are made in casings and generate vibrations by lower and upper crank mechanisms respectively. The vibrators' casings are made as identical metal corrugated shells being thin-walled bodies of rotation which in the vertical plane of their sections provide for complex truncated geometric figures by corrugation peaks points, the figures are formed by mean intersection of three circles with the centres being the vertices of a regular triangle and with the radiuses being equal to the altitude of the said triangle. Disks with guide posts are rigidly fixed inside the shells and are set in the centre in a horizontal plane. The disks are fitted by cylindrical protrusions. Four protrusions are symmetrically set on the outer cylindrical parts of cups. 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 at the diameters of recesses formed on the outer surface of the metal corrugated shells by the set of the smallest corrugations out of the corrugations of the lower and upper vibrators.

EFFECT: expanded performances and provision for the creation of two vibration fields of different frequency for the whole volume of a mixing chamber for the concrete mix components being mixed.
