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

FIELD: machine building.

SUBSTANCE: mixer comprises a mixing chamber, a rotor with blades. 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 casings and generate vibrations by lower and upper crank mechanisms The vibrators' casings are made as identical metal shells being corrugated thin-walled bodies of rotation which in the vertical plane section provide for complex truncated geometric figures by corrugation peaks points, the figures are formed by central intersection of four circles with the centres being the vertices of a square and with the radiuses being equal to the diagonal of the said square. Discs with guide posts are rigidly fixed inside each shell in the centre in the horizontal plane, the guide posts are to provide for stable directed translatory motion of stems from a sliding pair formed by the guide post of the lower mixing chamber part and the lower vibrator stem of the lower crank mechanism, and from a sliding pair formed by the guide post of the upper mixing chamber part, the guide post of the blade rotation drive and the upper vibrator stem of the upper crank mechanism respectively. The discs of the lower and upper vibrator are fitted by cylindrical protrusions to be inserted and fastened along the inner diameter of the springs installed in cups. Stems are rigidly attached to the centres of the cups' inner parts, and pushers are attached to the centres of the cups' outer parts, the pushers are rigidly coupled by the other end with the inner parts forming the smallest corrugations from those of the metal corrugated shells. Four protrusions are symmetrically set on the outer cylindrical parts of the cups. A spring is installed between the casings of the lower and upper vibrators along the diameters of recesses formed by the smallest corrugations from those of the metal corrugated shells at the lower and upper vibrator casings.

EFFECT: provision for the creation of two vibration fields of different frequency for the whole volume of a mixing chamber for the concrete mix components to ensure qualitative intensification of component mixing process on the whole.
