Abstract

The invention provides a method for recycling a waste emulsion explosive in a rock powder emulsion explosive. The method comprises the following steps of pre-treating the waste emulsion explosive to form a mixed solution; then, mixing the mixed solution and rock powder emulsion explosive water and oil according to a specific proportion; and carrying out vacuum drying at negative pressure to obtain the rock powder emulsion explosive, wherein the mixed solution obtained through pre-treating the waste emulsion explosive accounts for 1.0-5.0% of the mass of the prepared rock powder emulsion explosive product, the added rock powder emulsion explosive water accounts for 92.0-95.0% of the mass of the prepared rock powder emulsion explosive product, and the rock powder emulsion explosive oil accounts for 3.0-6.0% of the mass of the prepared rock powder emulsion explosive product. Compared with the traditional other waste emulsion explosive treating technologies, the method has the advantages that the production process is simple, the product is stable and reliable in quality as well as economic and environment-friendly, and the problems of raw material waste and environment pollution which are caused by waste emulsion explosive destruction are avoided.

Description

technical field [0001] The invention relates to a treatment method for recycling waste emulsion explosives applied to rock powder emulsion explosives. Background technique [0002] At present, there are mainly the following methods for the disposal of scrapped emulsion explosives. [0003] (1) Add processing online. It is mainly aimed at the treatment of latex matrix or finished drug body with good milk quality. For the primary or secondary emulsification medium and low temperature sensitization production line, most of them manually add a small amount and multiple times directly from the inlet of the sensitizer; for the high temperature sensitization line, they add a small amount and multiple times from the latex matrix hopper in front of the mixer. This method is the most simple and feasible, and most emulsion explosive manufacturers use this method to dispose of scrapped emulsion explosives. But on the one hand, there are many transfer links of scrapped emulsion explos...
