VIBRATION MIXER Russian patent published in 2017 - IPC B28C5/16 

FIELD: building.

SUBSTANCE: 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. That is the creation of two different frequency vibration fields over the entire volume of the mixer chamber for blending the components of the concrete mixture is ensured. Each of them 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 complex truncated geometric figure consisting, in aggregate, of equal semicircles, which extreme points of intersection form the vertices of the square, with simultaneous ability 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 field, corresponding spiral and screw shape with creation of dynamic effect of the given vibration fields overlapping with simultaneous formation of multidirectional vibrations in two-frequency range that completely exclude the presence in the chamber of the mixer "blind" areas, additional vibration effects on blending components and ensures uniform amplitude distribution of each vibration field in the mixing chamber with quality intensification of 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 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. Thus, inside each housing the discs with guide bars are rigidly fixed in the central part of horizontal plane, which are designed 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 of the lower crank mechanism, and from the translational pair formed by the guide bar of the upper part of the mixing chamber, by the guide bar of the rotation drive of the blades and the rod of the upper vibrator of the upper crank mechanism respectively. Wherein the discs of lower and upper vibrators are made with cylindrical projections, which function is to insert and fix springs in the internal diameters of buckets having the function of free compression / release; where the rods are rigidly mounted at the central inner parts of buckets, and the pushers are rigidly mounted to outer parts of the buckets with their other ends are rigidly mounted to the inner parts forming the smallest of the goffer bodies made for the function of vibration excitement from the smallest of the goffer bodies of vibrators. Wherein four projections are symmetrically secured at the outer cylindrical parts of the buckets, whose function is to transmit reciprocating motion to disks designed to execute homogeneous distribution of vibration fields from the smallest corrugation bodies to the places of bodies fixing by means of creation of homogeneous amplitude displacement values of each point of outer generatrix of corrugated bodies, while spring compression to the stop into rubber gaskets made for shock absorption of projections collision with disks. Housings of vibrators are made in the form of uniform corrugated metal coverings, which are corrugated thin-walled bodies of rotation forming complex truncated geometrical shapes in the vertical section at top points of the corrugation consisting of equal semicircles in the aggregate, which extreme points of intersection form vertices of a regular square adapted to create two identical in amplitude and different in frequency vibration fields, each of which correspond by the shape to the corrugated contour of the given bodies of rotation with multi-directional vibrations. The spring is located centrally between the housings of the lower and upper vibrators according to hollows diameters formed by the smallest of corrugates in the form of corrugated metal coverings of the upper and lower vibrators housings; the function of the spring is to create aggregated two-frequency vibration field, which corresponds to the spiral and screw shape of the spring with formation of overlapping dynamic effect 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 allows expanding the store of technical means and new features achievement by the claimed objects.
