FIELD: construction.SUBSTANCE: vibration mixer comprises a mixing chamber with windows for charging and discharging materials, a rotor with a rotation drive made with blades. In the upper and lower parts of the mixing chamber in the centre there is a lower and upper vibrators fixed rigidly and made in bodies, with excitation of oscillations by means of upper and lower crankshaft mechanisms accordingly, and with the function of development of effect of vibration fields imposition in the centre of the mixing chamber from the lower and upper vibrators. Bodies of vibrators are made in the form of identical metal corrugated shells that represent corrugated thin-walled solids of revolution, forming complex truncated geometric figures in the cross section of the vertical plane at the points of the corrugation tops, and the figures are formed with central crossing of four circumferences with centres making tops of the square, and radii equal to the diagonal of this square, and made as capable of creating two vibration fields of identical amplitude and different frequency, each corresponding in shape to the corrugated contour of these solids of revolution, with differently directed oscillations, inside each of which in the centre in the horizontal plane there are discs rigidly fixed with guide stands, the function of which is to develop stable reciprocal movements of stems from a reciprocal pair formed by the guide stand of the lower part of the mixing chamber and the stem of the lower vibrator, the lower crankshaft mechanism and from the reciprocal pair formed by the guide stand of the upper part of the mixing chamber, by the guide stand of the drive of blades rotation and the stem of the upper vibrator, the upper crankshaft mechanism accordingly. Discs of the lower and upper vibrators are made with cylindrical protrusions, the function of which is the possibility to insert and fix springs at the internal diameter, which are installed with the function of free compression/release in sleeves, to the centres of the internal parts of which there are stems rigidly fixed, to the centre of the external parts - pushers, which are rigidly fixed by the other end to internal parts that form smallest corrugations, metal corrugated shells, and made with the function of excitation of oscillations from the least corrugations of vibrator bodies. Four protrusions are symmetrically fixed at external cylindrical parts of each sleeve.EFFECT: complete prevention of dead zones in a mixing chamber and high-quality intensification of a process of components mixing.3 dwg |
