The specific embodiment
Below in conjunction with Figure of description the present invention is described further.
A kind of method that is used for the sodium hydrosulfite packing of the present invention may further comprise the steps successively:
1), adopt en-masse conveyer to carry out the sodium hydrosulfite automatic transport;
2), en-masse conveyer export insurance powder is sent into sieving machine and is sieved;
3), sieving machine export insurance powder is sent into second en-masse conveyer;
4), the second en-masse conveyer export insurance powder is sent into the automatic weighing machine structure and is carried out weighing;
5), after the automatic weighing machine weighing sodium hydrosulfite is sent into the sodium hydrosulfite packing barrel and seal tube automatically.
En-masse conveyer is air-flow en-masse conveyer or helix closed formula conveyer in the step 1).
Step 2) sieving machine in is explosion-proof in line vibrating grizzly.
In the sodium hydrosulfite automatic transport process of step 1); After must considering that solving every batch of sodium hydrosulfite carries end; Can not deposit the sodium hydrosulfite material in the conveying machinery, otherwise can cause all that in the air sodium hydrosulfite decomposes heating, and cause burning because of being exposed in the air or meeting low amounts of water or be exposed to humidity.The way that solves is that the closed conveying of air-flow is adopted in (1): the gas of employing must be with the nitrogen of N2 >=99.9% (when sodium hydrosulfite is produced as atmosphere gas), after every batch of sodium hydrosulfite automatic transport end, blows for a moment with nitrogen more and to get final product; (2) adopt helix closed formula to carry: after every batch of sodium hydrosulfite automatic transport finishes, the spiral of carrying to be reversed, the sodium hydrosulfite of the balance in the spiral is all drawn off get final product.Simultaneously, in sodium hydrosulfite automatic transport process, solve the static that sodium hydrosulfite produces in the automatic transport process derives timely, otherwise, can cause burning because of the generation of static electricity spark.The way that solves is that sodium hydrosulfite automatic transport machinery is carried out actv. ground connection, in sodium hydrosulfite automatic transport process, the static that produces is imported the earth timely.
