AERODYNAMIC PLANT FOR THE BULK MATERIALS ENRICHMENT Russian patent published in 1994 - IPC

FIELD: bulk materials enrichment. SUBSTANCE: aerodynamic plant has a charge bin supported on vibration drying and dedusting module 2 which is supported on a supercharge module provided with air heater 5. Module 2 has heaters 3, shelves, injector 6 for liquids and gases being sprayed and connected to aerodynamic tube 7 module provided with adjustable shelves 8 and electrical winding 9. Aerodynamic tube module is connected to dynamic disconnection chamber 10 provided with shelves 11, perforated suction means 12, baffled vibropanel 13 and dust ventilator 14. Dust ventilator 14 is associated with vibration drying and dedusting modules by airlines 15 with inclination 16, the controlling being operated from the control disk 17. The bulk material is fed to vibration drying and dedusting module 2 and is being dried and dedusted there while pouring over shelves 4 in the heat treatment zone of heaters 3. The grains further enter tube 7 wherein it is conveyed in an eddy flow. If necessary a liquid or a gas is injected into the flow. The grains are cleaned up from shelves 8 and electrical winding 9. The grains further fly in into chamber 9, repeatedly impinge baffle 13 in an ultrasonic field and fare falling down while pouring over the shelves. EFFECT: improved quality of enrichment. 3 cl, 1 dwg
