[0044] In order to better demonstrate the implementation process of the purification device for the production of electronic-grade silicon micropowder, this embodiment proposes an implementation method of the purification device for the production of electronic-grade silicon micropowder, including the following steps:
[0045] Step 1: Put silicon micropowder on the grading sieve material 33 in the outer casing 31, and the sieve material cylinder 331 drives the sieve material rod 332 to expand and contract, thereby driving the first sieve material net 333, the second sieve material net 334 and the third sieve material net The material net 335 lifts back and forth, and the first sieve material net 333, the second sieve material net 334 and the third sieve material net 335 classify and filter the silicon micropowder, effectively removing the particles in the silicon micropowder;
[0046] Step 2: The sieved silicon-removing micropowder falls to the electromagnetic conveying network...
