Area；The gas shock swings gentle concussion screening lower grid plate (33) of screening top grating (32) and is arranged at intervals on the upper of sorting cabin (30)
In lower two sidewalls, completed according to the sieve sieve mesh number difference that gas shock swings the gentle concussion screening lower grid plate assembly of screening top grating wait sieve
Divide the screening of particle；The concussion gas generator (34) supplies mould group (1), screening from steady state is coupled with reduction atmosphere respectively
The gas distribution pipe of gas up and down in cabin (30) is connected with sorting particle receiver (35) connecting tube, swings screening mould group (3) for gas shock and provides
Shake air-flow；The sorting particle receiver (35) is arranged symmetrically with the second flow-controlled device (31), realizes the receipts of particle after screening
Collection；The gas shock swings the respective opening for independently executing screen of gentle concussion screening lower grid plate (33) of screening top grating (32) and closes
Conjunction movement, gas shock swing screening lower grid plate (33) screen closed action linkage concussion gas generator (34) closing motion, make gas shock
It swings screening mould group (3) and microparticle transfer mode is entered by screening mode, gas shock swings screening top grating (32) and driven by servo motor
The dynamic opening and closing for executing screen provide constant current gas interactions with the gentle cycle power device of self coupling (14), swing sieve in gas shock
Divide between top grating (32) gentle concussion screening lower grid plate (33) and form high voltage pulse air-flow, raising gas shock swings sieve mould group (3) and divides
Select the transmission efficiency of microparticle.
