Description

Technical Field

[0001] The invention belongs to the technical field of emulsion explosive production equipment, and more specifically, relates to an emulsion explosive sensitizer intelligent filling system. Background Art

[0002] Sensitizer for emulsion explosive is a kind of active substance that can improve the detonation sensitivity of explosives. It can increase the potential energy of oil-water mixed system and reduce the external energy required for explosive explosion. When the oil-water mixed system is impacted by external energy, the bubbles released by the foaming agent in the system are instantly compressed strongly, forming a "hot spot" of high temperature and high pressure under adiabatic conditions. After reaching a certain critical state, the substances in and around the bubbles first decompose, and then expand to combustion and explosion. The precise control of the ratio of sensitizer to latex matrix is ​​an important factor affecting the storage performance and detonation performance of emulsion explosives.

[0003] Emulsion explosives are one of the environmentally friendly products among various industrial explosives. In the development of my country's civilian blasting equipment industry, major products such as industrial explosives and industrial detonators have basically achieved continuous and automated production. Therefore, optimizing the production process of emulsion explosives and improving the efficiency of the continuous sensitization system are one of the keys to establishing a truly continuous emulsion explosive production line. However, the backwardness of the foaming agent addition device currently used in China directly affects some properties of emulsion explosives, such as the stability of emulsion explosives and the problem of foaming aftereffect.

[0004] The existing open-type cooling full-continuous emulsion explosive production line is the mainstream production method of emulsion explosives in my country.
