Continuous technique for preparing emulsifying explosive and charging

Abstract

The invention provides a continuous producing process for pharmacy and charging of emulsion explosive, which comprises the following steps: (1) aqueous phase solution and oil phase solution are respectively prepared; (2) the aqueous phase solution and the oil phase solution are delivered into a colostrum device for mixing, and after the process of colostrum, the aqueous phase solution and the oil phase solution are delivered into a static mixer for refining colostrum; (3) after the refined colostrum latex are delivered into a sensitized charging system for sensitized treatment, charging is carried out and after being cooled by a cooling system, the products are delivered to a packaging system for packaging. The technique proposal of the process is characterized by no warming after the process of the colostrum, high safety, and little damage of latex.

Description

technical field [0001] The invention belongs to the production process of emulsion explosives, in particular to a continuous production process for the preparation and charging of emulsion explosives. Background technique [0002] At present, there are many problems in the continuous production process of emulsion explosives in the prior art. [0003] First of all, in the existing continuous production process of emulsion explosives, it generally includes the steps of preparing water phase solution and oil phase solution, colostrum, essence milk, cooling, sensitized charge and packaging in sequence. Using such a process method, after the latex is made, the colloid is cooled by a continuous closed cooler, a steel belt cooler or a water-immersed continuous cooler. Chemical sensitizers or physical sensitizers to form chemically or physically sensitized emulsion explosives. With this process of cooling first and then sensitizing the charge, when the latex is cooled, the latex ...

AI Technical Summary

Problems solved by technology

Using this process of cooling first and then sensitizing the charge, when the latex is cooled, the latex will be damaged to varying degrees because it is directly immersed in water or stirred and scraped by the cooler.

[0004] Secondly, in the existing continuous production process of emulsion explosives, the fine emulsifiers all use dynamic shear emulsifiers, which consume a lot of power and have low production capacity

Moreover, using a rotary fine emulsifier, the temperature of the latex after emulsification is generally higher than the temperature of the water and oil phases. Regardless of whether there is a seal, after the oil and water phases are cut off or the sealed cooling water is cut off, such as when the emulsifier is still running, All are prone to the danger of explosion caused by heat accumulation, so the safety is poor

[0005] Finally, because the drug state becomes viscous after cooling, it increases the difficulty of subsequent charging. The sensitized charging system generally uses a paper tube charging machine for charging, and the charging efficiency is low.
