FIELD: construction.SUBSTANCE: vibrating mixer includes a mixing chamber with material loading and unloading openings and a rotor with blades. Two devices are rigidly fixed in the centre in lower and upper parts of the mixing chamber: lower and upper vibrators made in housings with excitation of oscillations by means of lower and upper crank-and-rod mechanisms respectively. Housings of vibrators are made in the form of similar corrugated metal covers representing thin-wall rotation bodies forming complex flattened geometrical forms in the section of vertical plane at vertex points of corrugations, which are formed with middle intersection of three circles with centres representing vertexes of a regular triangle and radii equal to height of this triangle. Inside covers there rigidly fixed in the centre in horizontal plane are discs with guide posts. Discs of lower and upper vibrators are provided with cylindrical projections, the function of which is possible insertion and fixing along inner diameter of springs installed with a function of free compression/tension in shells, to the centres of internal parts of which stocks are rigidly attached, and pushers are attached to the centre of external parts, which are rigidly fixed with the other end to internal parts forming the smallest corrugations of corrugated metal covers, and having the function of excitation of oscillations from the smallest of corrugations of vibrator housings. Four projections are symmetrically fixed on external cylindrical parts of shells.EFFECT: enlarging the range of technical means and providing the possibility of creating throughout the volume of the mixer chamber for mixed components of the mixture of two vibration fields different as to frequency.3 dwg |
