METHOD OF MIXING OF THE BULK MATERIALS AND THE AERODYNAMIC DEVICE FOR ITS REALIZATION Russian patent published in 2007 - IPC B01F3/18 B01F13/02 

FIELD: chemical industry; food industry; building industry; other industries; methods and devices for mixing of the bulk materials.

SUBSTANCE: the inventions are pertaining to the mixtures preparation, in particular, to the methods of mixing of the bulk materials and may be used in the feed mill industry, chemical industry, alimentary industry, building industry and other industries. The method of mixing the bulk materials includes the feeding of the air and the mixture components tangentially into the container and their stirring in the suspension state. The air and the individual components of the mixture conduct jointly by suction due to making rarefaction in the container with the simultaneous batching by the tangential branch-pipes and the subsequent mixing of the components of the mixture in one working zone. The aerodynamic device contains the conical body, the cover with the air discharge ducts, the centrifugal ventilation wheel with the blades, the working chamber, on the lateral surface of which there are several tangential branch-pipes for injection of the air together with the mixture components. The tangential branch- pipes have different diameters and are arranged sequentially rising from the smaller diameter to the greater diameter on one horizontal plane, and the height of the blades of the centrifugal ventilation wheel should be equal or no less than the greatest diameter of the sucking tangential branch-pipe. The inventions ensure the increased effectiveness of the process of mixing of the bulk materials and the increased efficiency of the mixer.

EFFECT: the inventions ensure the increased effectiveness of the process of mixing of the bulk materials and the increased efficiency of the mixer.
