VIBRATION MIXER Russian patent published in 2017 - IPC B28C5/00 

FIELD: building.

SUBSTANCE: invention allows expanding the store of technical means and new features gaining by the claimed objects, which is achieved by that the vibration mixer consists of a mixing chamber with windows for materials loading and unloading respectively, the rotor with blades and rotary drive. In the upper and lower parts of the center of the mixing chamber the upper and lower vibrators are rigidly fixed, made in corrugated bodies with vibration excitement by means of lower and upper crank mechanisms, respectively, with the function of creating the effect of vibration fields overlapping in the center of the mixing chamber from the lower and upper vibrators respectively. Inside each housing the disks with guide bars are rigidly fixed in the center of horizontal plane which function is to create sustainable directional translational movement of the rods of the translational pair formed by the guide bar of the lower part of the mixing chamber and the rod of the lower vibrator, the crank mechanism, and from the translational pair formed by the guide bar of the upper part of the mixing chamber, the guide bar of the rotor drive, rotor blades and the rod of the upper vibrator, the upper crank mechanism respectfully. Wherein the disks of the lower and upper vibrators are performed with cylindrical projection arranged for insertion and fixing of a spring along the internal diameter in the bucket with the function of free compression / release; with the rod rigidly mounted at the central inner part of the bucket and a pusher rigidly fixed to its central external part with its other end rigidly fixed at the inner part forming the smallest of the corrugations with the function to excite oscillations from the smallest of the corrugations of the vibrators housings. Wherein four projections are symmetrically secured at the outer cylindrical parts of the buckets which function is to transmit reciprocating motion to the disks, to execute homogeneous distribution of the vibration fields from the smallest corrugations of the housings to the places of fixing of housings by means of creation of homogeneous amplitude displacement values of each point of outer generatrix of the corrugated housings, while spring compression to the stop into rubber gaskets made for shock absorption of projections collision with the disks. Housings of the vibrators are made in the form of uniform corrugated metal coverings, which are corrugated thin-walled bodies of rotation forming truncated equal hexagon in the vertical section at top points of the corrugation adapted to create two identical in amplitude and different in frequency vibration fields, each of which corresponds by its shape to the corrugated contour of the given bodies of rotation with multi-directional vibrations. Besides, the spring is located (in the center, between the housings of the lower and upper vibrators) in the hollows formed by the smallest of the corrugations of corrugated metal coverings in accordance with the hollows diameter which function is to create aggregated two-frequency vibration field, which corresponds to the spiral and screw shape of the spring with formation of dynamic effect of overlapping of the given vibration fields, and additional vibration effects on the components being mixed from the upper and lower housings of the vibrators respectively.

EFFECT: invention relates to the devices for concrete compounds mixing and can be used in the building materials industry, construction and other fields of construction industry for the production of multi-component mixtures.
