CENTRIFUGAL MIXER Russian patent published in 2005 - IPC

FIELD: food industry; chemical industry; other branches of industry; production of devices for continuous preparation of mixtures of the loose materials.

SUBSTANCE: the invention is pertaining to the devices for continuous preparation of mixtures of the loose materials and may be used in food, chemical and other industries. The centrifugal mixer contains: a vertical cylindrical body; a cover, on which there are the fixed connecting pipes for feeding of the source materials; a discharge connecting pipe; a driving shaft with an installed on it rotor made in the form of a disk, on which there are in the form of the disk on which one are the concentrically mounted hollow thin-wall truncated cones, the height of which and angle of the generatrix inclination to the base are increasing from the central part to the periphery. At that on the surface of the middle and the outside cones there are tangential holes. In the upper part of the body limited by the surface of the cover a static deflector is installed. The design of the apparatus ensures mixing of materials in the thin, rarefied, intersecting layers with usage of the direct and reverse recycles. The intensification of the mixing process is reached by that on the surface of the middle and the outside cones there are tangential holes, and also in the upper part of the body limited by the surface of the cover a static deflector is mounted. Due to that the invention ensures the reverse recirculation of the material flow, an additional turbulization of the mixed components, a decrease of the number of the quiescent areas in the various parts of the rotor and a degree of formation dust-gas mixes, that in result positively effects on the quality of the mixture.

EFFECT: the invention ensures the reverse recirculation of the material flow, an additional turbulization of the mixed components, a decreased number of the quiescent areas in the rotor and a degree of formation dust-gas mixes.
