Description

Technical Field

[0001] The utility model relates to the technical field of emulsion explosive ground station, in particular to a full-static emulsification system of an emulsion explosive ground station. Background Art

[0002] Emulsion explosives refer to a type of water-in-oil latex-type water-resistant industrial explosives prepared by emulsification technology. It is a special emulsified system of water-in-oil type, with fine droplets of oxidant aqueous solution as the dispersed phase, suspended in a continuous medium composed of oil-like substances containing dispersed bubbles or hollow glass microspheres. At present, the emulsification process in the production of emulsion explosives in my country mainly has the following three emulsification methods, namely, medium-high speed mechanical stirring single-stage emulsification, medium-low speed mechanical stirring combined static fine emulsifier and multi-stage pipeline static mixing emulsification. Among them, the medium-to-high speed mechanical stirring single-stage emulsification cannot meet the requirements of safe production because of its emulsifier's defects such as too high mechanical stirring speed, high energy consumption, small gap between stator and rotor, easy heat accumulation, and metal friction during mechanical failure that easily causes explosion accidents; the safety of medium-to-low speed mechanical stirring coarse emulsion + static fine emulsification has been greatly improved compared with the medium-to-high speed mechanical stirring single-stage emulsification, but its coarse emulsion is still mechanically stirred, and there are certain safety risks and high energy consumption problems like the single-stage emulsification process. At the same time, the latex matrix is ​​transported between the dynamic coarse emulsion and the static fine emulsion through a Class 0 equipment screw pump, which further increases the danger points. These problems have attracted the attention of production companies and are expected to be further improved.

[0003] Therefore, in order to improve the dynamic stirring method, a static emulsification mode has emerged. Patent document CN220485582U discloses a fully static emulsification sensitization device for emulsion explosives. The entire emulsification process does not require a stirring device. A fully static emulsification mode is formed by spraying and shearing, which avoids the problem of safety accidents caused by stirring and the problem of poor static emulsification effect. The present application provides a fully static emulsification system for an emulsion explosive ground station using the fully static emulsification sensitization device for emulsion explosives, thereby avoiding the problem of safety accidents caused by emulsification by stirring in the emulsion explosive ground station emulsification system in the prior art, and also avoiding the problem of poor static emulsification effect.

[0028] See also Figure 1 and Figure 2 The embodiment of the utility model provides a fully static emulsification system 100 for an emulsion explosive ground station. The fully static emulsification system 100 for an emulsion explosive ground station includes a water phase storage tank 110, an oil phase storage tank 120 and a fully static emulsifier 130. The water phase in the water phase storage tank 110 is transported to the fully static emulsifier 130 through a water phase pump 111, and the oil phase in the oil phase storage tank 120 is transported to the fully static emulsifier 130 through an oil phase pump 121.

[0029] The fully static emulsification system 100 of the emulsion explosive ground station includes a hot water tank 150 and an ammonium nitrate crusher 160 . The hot water tank 150 is used to provide hot water to the water phase storage tank 110 through a metering pump. The ammonium nitrate crusher 160 is used to crush the ammonium nitrate. The crushed ammonium nitrate is transported to the water phase storage tank 110 through a screw conveyor 170 .

[0030] When the fully static emulsification system 100 of the emulsion explosive ground station provided by the embodiment of the utility model needs to prepare a latex matrix, the hot water tank 150 provides hot water to the water phase storage tank 110 through a metering pump, the ammonium nitrate crusher 160 is used to crush the ammonium nitrate, and the crushed ammonium nitrate is transported to the water phase storage tank 110 through a screw conveyor 170, the hot water and the crushed ammonium nitrate are mixed to prepare a water phase, the water phase in the water phase storage tank 110 is transported to the fully static emulsifier 130 through a water phase pump 111, and the oil phase in the oil phase storage tank 120 is transported to the oil phase storage tank 120 through an oil pump 111. The phase pump 121 delivers the phase to the fully static emulsifier 130, which performs fully static emulsification on the incoming water phase and oil phase.
