Patent ID: 10807125

Abstract:
The group of inventions can be used in agriculture as well as the food, chemical, mining, metallurgical and construction industries for the fractional separation of bulk mixtures. The group of inventions consists of a method of impeller-driven injection of gas in aerodynamic separator, wherein the gas flow is directed at an angle required for the separation process by tilting the impeller axis. Then the flow of gas is divided into inner and outer flows by an internal conical ring 5. After that the inner and outer flows are straightened by directing them through profiled blades of the inner and outer sections 6 of the stator 4. The slowdown of the flow in the center is eliminated by an exhaust cone 7. Finally, the sectional shape of the flow is changed from round to square or rectangular by passing the flow through supply channel. The proposed group of inventions also consists of a gas boosting unit 12 that is used for the implementation of the above-identified method, wherein the above-identified method and blowing unit 12 are used. The application of a group of inventions for the separation of bulk mixtures leads to a reduction in energy consumption, simplify the design of nodes and improving the quality of the fractional separation of the bulk mixture.
