FIELD: machine building.SUBSTANCE: vibration mixer comprises a mixing chamber, a rotor with blades. In the top and bottom parts of the 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 respectively. 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 mean 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. Disks with guide posts are rigidly fixed inside each shell and are set in the centre in the horizontal plane. The disks of the lower and upper vibrators are provided with cylindrical protrusions able of being inserted and fastened along the inner diameter of the springs installed so that they can be freely compressed and released 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 forming the smallest corrugations out of the metal corrugated shells' corrugations. Four protrusions are symmetrically set on the outer cylindrical parts of the 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 along 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: provision for qualitative intensification of component mixing process on the whole.4 dwg |
