| Abstract: | 5X-5 air-screen separator was designed.Its elementary structure and working process were introduced,particularly detailed the structural design and working principle of feeding system,pre-inspiration system,screening system,post-ascending system and post-inspiration system.Aspiration system was designed as double systems of winds with positive-inverse pressure aspiration,realized to clean light mishmashes twice from both feeding side and discharge port,ensuring high cleaning efficiency.Screening system was designed as upper and netherbins which were configured inversely with equalinertia,successfully reduced vibration and noise.Motor of screening system can be regulated stepless,with the vibration frequency ranged from 200 to 1 000 r/min.The main technical parameters of wheat seeds cleaning experiment were:separation rate 99%,cleanliness 98%,cleaning rate of grass seed 90%,breakage rate 0.092%,practical productivity 0.65 t/(kW·h),noise 84 dB(A),dust concentration 6.8 mg/m3. |
