Technical Field

The invention relates to the field of fireworks and crackers, in particular to a precise pyrotechnic composition charging and mixing technology.

Background

At present, in the production process of fireworks and crackers, an oxidant and a reducing agent need to be fully and uniformly mixed, then the mixed materials are added into each barrel, and finally operations such as bottom sealing, packaging and the like are carried out. As the powder is obtained after the oxidant and the reducer are mixed uniformly, the explosion and deflagration risks exist, and the friction is large and the dosage is large in the material mixing process, so that the medicine mixing is the most dangerous link in the whole production.

Moreover, the charging method commonly used at present is to arrange a plurality of barrels into a square matrix in a fitting manner, then to scatter the medicine above the barrels, and to fall into the barrels under the action of gravity. This mode of production can cause a great deal of powder to overflow and cause serious dust pollution. For this reason, it is also necessary to provide a drug recovery device for recovering the scattered powder, which further increases the cost of the equipment.
