VIBRATION MIXER Russian patent published in 2017 - IPC B28C5/26 

FIELD: building.

SUBSTANCE: invention allows expanding the store of technical means and new features achievement by the claimed objects. That is, the creation of two different frequency vibration fields over the entire volume of the mixer chamber for blending components of the concrete mixture is ensured. Each of the vibration fields correspond as for their form to corrugated contour of three-dimensional rotation body, forming in vertical plane section at top points of the goffer the truncated regular pentagon with the possibility to create overlay effect of the given vibration fields in the center of the mixing chamber providing the possibility of creating a plurality of cumulative two-frequency fields, each of which corresponds to spiral and screw shape with creation of dynamic effect of the given vibration fields overlapping with simultaneous formation in the two-frequency field of multidirectional vibrations that completely exclude the presence in the chamber of the mixer "blind" zones, additional vibration effects on blending components and ensure uniform amplitude distribution of each vibration field in the mixing chamber with quality intensification of the mixing process of these components as a whole. The technical result is achieved in that the vibration mixer comprises 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. The disks are rigidly fixed with guide bars inside both housings in the center of the horizontal plane, which function is to create sustainable directional translational movements 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, lower crank mechanism and from the translational pair formed by the guide bar of the upper part of the mixing chamber, guide bar of the rotation drive of the blades and the rod of the upper vibrator, upper crank mechanism respectively. Besides, the disks of the lower and upper vibrators are performed with cylindrical projections arranged for insertion and fixing of springs along the internal diameter of the buckets with the function of free compression / release; with rods rigidly mounted at the central inner parts of the buckets and the pushers rigidly fixed to their central external parts with their other ends rigidly fixed at the inner parts forming the smallest of the corrugations of the housings with the function to excite oscillations from the smallest corrugations of the vibrators housings. Wherein four projections are symmetrically secured at the outer cylindrical parts of the buckets whose function is to transmit reciprocating motion to the disks intended to execute homogeneous distribution of the vibration fields from the smallest corrugations of the housings to the place of fixing of the given 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 collision force of projections and disks. Housings of vibrators are made in the form of uniform corrugated metal coverings, which are corrugated thin-walled bodies of rotation forming truncated regular pentagons in the vertical sections at top points of the corrugation adapted to create two identical in amplitude and different in frequency vibration fields, each of which correspond to the corrugated contour of the given bodies of rotation with multi-directional vibrations. The spring exciter is located between the housings of the lower and upper vibrators in the center which is made in the form of spring group consisting of, at least, two springs of different diameters fixed in hollows according to their diameters formed on the outer surface of corrugated metal coverings by the smallest of the corrugates of the upper and lower vibrators, the function of which is the creation of a set of groups of aggregated two-frequency vibration fields, each of which corresponds to the spiral and screw shape of the central springs of the spiral exciter to form 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.
