The specific embodiment:
Shown in accompanying drawing: this equipment comprises motor 1, contactless shaft coupling 2, front head plate 3, fore bearing support assembly 4, main shaft 5, supersonic oscillations disperser 6, rear head plate 7, rear bearing support assembly 8, passivation cylindrical shell 9, rubber flap 10, its contactless shaft coupling 2 is arranged on an end of front head plate 3, motor 1 is arranged on above the contactless shaft coupling 2 by motor installing rack 11, main shaft 5 is by two head plates 3 before and after being arranged on, front and back bearings support assembly 4 on 7,8 are arranged on the center of passivation cylindrical shell 9, front head plate 3 and rear head plate 7 are arranged on the two ends of passivation cylindrical shell 9, passivation cylindrical shell 9 is provided with supersonic oscillations disperser 6, and main shaft 5 is provided with rubber flap 10.
Have gas outlet 12 on the described front head plate 3, have meal outlet 13 on the rear head plate 7;
Described passivation cylindrical shell 9, front head plate 3 and rear head plate 7 constitute an airtight working cavity, have powder inlet 14, observation window 15 and air inlet 16 in a side of passivation cylindrical shell 9;
Described passivation cylindrical shell 9 is double-deck sandwich type structure, and it is tilted setting;
Described meal outlet 13 places have vacuum dish valve 17.
Above-mentioned motor 1 is the adjustable big torque specific type of electric machine of low speed, contactless shaft coupling 2 for the inventor in the first to file (patent No.: 00212240.5) be installed on the output shaft of motor 1, give main shaft 5 transmission of power by contactless shaft coupling 2, contactless shaft coupling 2 adopts seal sleeve 18 isolated sealings, to guarantee the vacuum of whole system, the power rotation that main shaft 5 is transmitted by motor 1 and contactless shaft coupling 2, and drive rubber flap 10 rotations that are arranged on the main shaft 5.Separation net 19 is used to isolate the high pure metal nano powder, is unlikely to when making its circulated inert gas the high-purity nm powder is flowed away with high-pressure inert gas.The meal outlet 13 that is used for powder delivery adopts 14 sealings of vacuum dish valve, and passivation cylindrical shell 9 is double-deck sandwich type structure design, and interlayer is that cooling layer passes through water quench, and inner chamber is a working chamber, and its top is provided with nano powder powder inlet 14.Be connected on the nano powder preparation equipment during powder inlet 14 work.Also be useful on the observation window 15 of its working condition of observation and the air inlet 16 that inert gas feeds on passivation cylindrical shell 9 tops.In addition, front head plate 3, rear head plate 7 adopt with sealing of O RunddichtringO and bolted with passivation cylindrical shell 9.Ultrasonic oscillator 6 is connected on the ultrasonic oscillator installing port of passivation cylindrical shell 9 bottoms, seal with seal cover 20 and O type rubber seal with passivation cylindrical shell 9 inner chambers, reunite to prevent its nano powder with ultrasonic oscillator 6 vibration high pure metal nano powders, particle is played peptizaiton.
