METHOD AND DEVICE FOR EMULSIFYING EMULSION EXPLOSIVE

摘要

The present invention relates to a method and device for emulsifying emulsion explosive: an oil phase and a part of a water phase having undergone split-flow enter a first stage coarse emulsion mixer; after mixing, the mixture together with a part of the water phase having undergone second stage split-flow enters a second stage coarse emulsion mixer; the obtained mixture together with a part of the water phase having undergone third stage split-flow enters a third stage coarse emulsion mixer for mixing; forming a coarse emulsion matrix after multiple stages of mixing, and finally completing emulsification after mixing in a multi-stage fine emulsion mixer. The method and device mix the water phase with the oil phase multiple times according to a desired ratio, thus greatly reducing the stored explosive, with no mechanical stirring or shearing, with no heat accumulation, and with low pressure, without requiring matrix pumping, thus enhancing safety.

主权项

1. An emulsifying method for an emulsion explosive, comprising the following steps of:
(1) letting an oil phase entirely enter a first stage coarse emulsion mixer; (2) letting a water phase enter a multi-stage coarse emulsion mixer by multiple control strategies in the manner of multi-stage split-flow; (3) keeping a last stage coarse emulsion mixer connected to a fine emulsion mixer; (4) mixing emulsion matrix in a multi-stage fine emulsion mixer before completing the emulsification.
