preparation example Construction

[0060] The preparation device of ultrafine CL-20 of the present invention is specifically as follows:

[0061] Such as figure 1 As shown, the preparation device of ultrafine CL-20 of the present invention includes a ball mill host 6, a mixer 3 and a material pump 5 connected to the ball mill host 6 by pipelines.

[0062] Such as figure 2 As shown, the ball mill host 6 includes a grinding chamber 6-6 with stirring, a grinding chamber upper cover 6-3, and grinding balls 6-5; the grinding chamber 6-6 is a cavity structure with an upper opening, and the grinding chamber upper cover 6 -3 Utilize the spring clip to fasten on the top of the grinding chamber 6-6 to cover its upper opening, and a rubber ring is arranged between the grinding chamber upper cover 6-3 and the upper opening of the grinding chamber 6-6 to cover its upper opening for sealing; grinding The chamber upper cover 6-3 is provided with a grinding chamber feed port 6-4, the bottom of the grinding chamber 6-6 is pr...

Embodiment 1

[0073] (1) Weigh 3.5kg of zirconia grinding balls (zirconium oxide purity 99.9%, sphericity 0.99) into the grinding chamber, the diameter of the grinding balls is 4mm, and the filling rate is 75%.

[0074] (2) Weigh 350g of raw material CL-20, measure 0.65L of grinding solution (distilled water) in a mixer with stirring, and stir well so that the two are fully mixed in the mixer to form a uniform CL-20 slurry. CL-20 slurry concentration is 35%wt.

[0075] (3) Input the above CL-20 slurry from the mixer through the circulation device (connect the pipeline between the mixer and the grinding chamber and the material pump on it) into the grinding chamber for circulating crushing and grinding: CL-20 slurry Enter the grinding chamber from the feeding port on the top of the grinding chamber for crushing and grinding, and then discharge it to the mixer from the outlet at the bottom of the grinding chamber, and then re-input the slurry into the grinding chamber through the circulation ...

Abstract

The invention provides a preparation device and a preparation method for ultrafine CL-20. The preparation device comprises a main grinding mill, a mixer and a material pump. A main ball mill comprises a grinding cavity with an agitator, and a grinding ball; the grinding ball is arranged in the grinding cavity. An agitator is arranged in the mixer, a discharge outlet and a cyclic feed inlet are formed in the mixer, the discharge outlet of the mixer is connected with a feed inlet of the main ball mill through a pipeline, a discharge outlet of the grinding cavity is connected with the cyclic feed inlet of the mixer by a pipeline, a discharge valve is arranged at a position, close to the grinding cavity, on the pipeline, and the material pump is arranged behind the discharge valve. The preparation method comprises the steps of adding the grinding ball into the grinding cavity of the main ball mill, then inputting the mixed slurry of active ingredient CL-20 and grinding liquid into the grinding cavity, circularly crushing and grinding, then discharging and performing vacuum filtration and drying, to obtain the ultrafine CL-20. The preparation device and the preparation method are simple to operate, high in safety, high in production efficiency, and capable of being widely applied to refinement of various energetic materials.

Description

technical field [0001] The invention relates to a refinement technology of energetic materials, and furthermore, relates to a device and method for rapid batch preparation of ultrafine CL-20. Background technique [0002] With the development of science and technology and the increasingly fierce confrontation of weapons, the refinement technology of explosives at home and abroad is in the ascendant. Because ultra-fine explosives have the following advantages: the detonation process is close to the ideal detonation law, and the potential internal energy of the explosion is developed; the thermal conductivity is good, and it is easy to conduct heat conduction, so that the hot spot of the explosion is not easy to form; Gradation, good dispersion performance, promotes a better and more uniform charge density; when subjected to impact loads, the impact force is quickly and evenly dispersed throughout the grain column, reducing impact sensitivity. Therefore, ultrafine explosives ...
