FIELD: machine building.SUBSTANCE: vibration mixer comprises a mixing chamber with the ports for loading and unloading of materials, a rotor with blades and a rotary drive. Lower and upper vibrators provided with casings are centred and rigidly fixed in the lower and upper parts of the mixing chamber and vibrations are generated by lower, central and upper crank mechanisms; the vibrators' casings are made as metal corrugated 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, the shells are able of generating three vibration fields identical in amplitude and different in frequency, two of the fields in the aggregate and one field separately correspond by shape to the corrugated contour of the said bodies of rotation, with differently directed oscillations. Inside the metal corrugated shell of the lower vibrator able of generating two vibration fields identical in amplitude and different in frequency with the help of the lower and the central crank mechanisms, a disk is set in the centre in the horizontal plane and is rigidly fixed, the disk is fitted by a cylindrical protrusion able of being inserted and fastened along the inner diameter of a spring installed so that it can be freely compressed and released in a cup, a connecting rod driven by the central crank mechanism is rigidly attached to the centre of the cup's upper inner part, and a pusher is attached to the centre of the cup's upper outer part, the pusher is rigidly coupled by its other end with the inner upper part of the metal corrugated shell of the lower vibrator casing and is provided with the possibility of generating vibrations from the upper part of the lower vibrator casing via the connecting rod by the central crank mechanism. The lower vibrator disk provides for the possibility of generating vibrations of the central part of the lower vibrator casing with the help of four pushers which by their upper part are symmetrically attached to the lower part of the disk and by the lower part are coupled in a movable pivot unit of the connecting rod of the lower crank mechanism. A disk with a guide post is rigidly fixed inside the metal corrugated shell in the centre in the horizontal plane. Four protrusions are symmetrically set on the outer cylindrical part of the cup.EFFECT: complete prevention of dead zone formation in a mixing chamber and qualitative intensified mixing of components.3 dwg |
