Description

Technical field:

[0001] The utility model relates to the technical field of emulsion explosive production equipment, in particular to an emulsion explosive filling device. Background technology:

[0002] Emulsion explosives are a type of latex-based explosives made by using an emulsifier to evenly disperse an ammonium nitrate solution in an oil phase solution. During blasting, a mixed emulsion explosive truck transports the latex matrix and sensitizer to the blasting site, where they are pumped into the blasthole via a pump and a rubber hose. The latex matrix and sensitizer mix to produce foam, filling the entire blasthole, and the explosive in the latex matrix is ​​then detonated to cause the blast.

[0003] In existing production, the discharge port of the emulsification equipment is connected to a hose. Workers temporarily fix the hose at the feed port on the top of the mixed emulsion explosive truck and transport and fill it through the hose. During the filling process, people need to climb to the roof to operate. If there is air in the pipeline during the filling process, the hose will shake violently, causing the hose to fall off and the emulsion explosive to spray out; or overflow due to overfilling. Emulsion explosives are explosives, and there is a risk of explosion when they are spread into the surrounding environment after being sprayed out; at the same time, the head of the hose extended into the silo will directly contact the emulsion, or the emulsion will splash, and the emulsion will remain on the head of the hose. After the solvent in the emulsion evaporates, a large amount of ammonium nitrate crystals will be produced at the pipe mouth, which is prone to explosion and poses a major safety hazard.
