Static sensitization method and static sensitization equipment for packaging emulsion explosives

Abstract

The invention relates to static sensitization equipment for packaging emulsion explosives. The static sensitization equipment comprises a static sensitizer (3), a colloid feeding hole (1) connected with the static sensitizer, a sensitizer feeding hole (2), an injection outer cavity (4), and a blocking chamber (6), wherein multiple rows of injection holes (5) are formed in the side wall; the sensitizer is mixed with an emulsion matrix, is ejected from the injection holes (5) under the action of the external pressure and is injected to the inner wall of the outer cavity (4), so that the emulsion matrix and the sensitizer form the first collision mixing; along with continuous entrance of the materials, repeated collision mixing is formed between the materials, the materials are pressed in the second-stage and third-stage sensitizers for repeating the collision mixing process, and finally, the emulsion matrix and the sensitizer are uniformly mixed. According to the equipment, the emulsion matrix and the sensitizer can be uniformly mixed under the condition that mechanical stirring is avoided, and a good sensitization effect can be achieved under the high/medium/low temperature conditions.

Description

technical field [0001] The invention relates to the production field of emulsion explosives, in particular to a method and equipment for static sensitization of packaged emulsion explosives. Background technique [0002] Due to its outstanding adaptability and safety performance, emulsion explosives have become the main varieties of industrial explosives after nearly 40 years of vigorous development. The sensitization process of explosives is to introduce a certain amount of fine air bubbles into the colloidal matrix. During the blasting process, a large number of hot spots will be gathered due to heating, and finally the performance of explosives can be fully exerted. At present, the sensitization methods of emulsion explosives at home and abroad are generally divided into two categories. One is high temperature sensitization. Most of this type of equipment adopts a closed structure and uses stirring to make the emulsification matrix and sensitizer uniformly mixed. Stirrin...

Problems solved by technology

At present, the sensitization methods of emulsion explosives at home and abroad are generally divided into two categories. One is high temperature sensitization. Most of this type of equipment adopts a closed structure and uses stirring to make the emulsification matrix and sensitizer uniformly mixed. Stirring the finished explosives in the lower closed cavity has very safety hazards; the other type is medium and low temperature sensitization, which is generally in an open or closed container, and the colloidal matrix and the sensitizer are uniformly mixed by dynamic stirring

These two sensitization methods are completed by mechanical shearing, the sensitization process is not safe, and too much stirring during the sensitization process will also cause the emulsion of the latex matrix, thereby affecting the performance of explosives
