The workflow of system is:
A, starting drive are put into the blanking tube of feed screw structure with the product zinc powder, are sent in the sieve powder case by the feed screw structure;
B, spring vibration screening mechanism carry out classification with the screening of product zinc powder, fall in the fine powder groove greater than the thin zinc powder of 126 purposes, are less than or equal to 126 purpose crude zinc powder and then fall in the meal groove;
C, conveying worm are sent to the fine powder feed opening with the thin zinc powder in the fine powder groove, carry out finished product packing;
D, startup blower fan suck the crude zinc powder in the meal groove in the bagroom along the meal discharge nozzle; Part crude zinc powder drops in the discharge box along tremie pipe; Few part crude zinc powder gets into staving; Tail gas behind the cloth bag filtration is from the blast pipe discharging, and the crude zinc powder that cloth bag is collected then falls in the discharge box of staving bottom;
E, send the crude zinc powder of collecting back to electric furnace and process again.
Beneficial effect:1. the charging of this sieve powder device and feed opening place adopt the mode that is flexible coupling, and are not easy in the blanking process to stop up, and prevent to fly up when powder from falling, thereby avoided the powder waste, have improved product yield.
2. this sieve powder device has good sealing, guarantees to sieve the powder overall process and under sealing state, accomplishes, and exogenous impurity can not get in the powder, and finished product purity is high.
3. should adopt bagroom to handle tail gas by sieve powder device, the bagroom that is adopted has good filter effect, only contains micro-powder in the tail gas after the filtration, has improved product yield when having avoided environmental pollution.
