FIELD: devices of air separation of loose material, for example grain, grain crop, vegetables and grass; cleaning and separation of grain at seed plants, farms, grain elevators; flour, combined fodder, chemical and other industries. ^ SUBSTANCE: proposed device has bin and vibrating chute, fluid oscillator with planar nozzles of different calibers mounted in flow in succession at increased varying pitch, acute angle of installation, nozzle caliber; device is also provided with receivers for finished and repeated fractions which are communicated with bin through transporting unit. Fluid oscillator is just high-frequency oscillator; no less than ten nozzles are provided; they are made with walls of guide passages whose length increases downward. Mounted in generator in succession before nozzles are three screens; finished fraction receivers exceed repeated fraction receivers by two; two finished fraction receivers are mounted at the end of flow. ^ EFFECT: improved quality of separated product; reduced separation cycle; increased productivity. ^ 2 dwg |
