Abstract

The invention relates to the technical field of energetic device production, in particular to an energetic material kneading device. According to the technical scheme, the energetic material kneadingdevice comprises a multi-cavity kneading assembly, a first feeding assembly and a second feeding assembly. The multi-cavity kneading assembly is provided with at least four kneading units which are sequentially communicated, each kneading unit comprises a kneading cavity, and a pair of mixing blades are arranged in each kneading cavity so as to sequentially achieve feeding, premixing, final mixingand discharging of energetic materials; the first feeding assembly is used for inputting a first solid-phase component of an energetic material into the multi-cavity kneading assembly; and the secondfeeding assembly is used for inputting a second solid-phase component of the energetic material into the multi-cavity kneading assembly. According to the invention, continuous mixing of energetic materials can be realized, the online dosage of kneading and mixing of the energetic materials can be reduced, continuous filling of the energetic materials can be realized, the intrinsic safety of the production process is improved, and the stable quality of the product can be ensured.

Description

technical field [0001] The invention relates to the technical field of energetic device production, in particular to an energetic material kneading device and method. Background technique [0002] Energetic materials, namely explosives, propellants and pyrotechnic powders, are widely used in military and civilian blasting and fireworks fields due to the release of large amounts of energy in redox reactions. Among them, the mixing uniformity of each component of the energetic material directly affects the performance of the energetic material itself, and the mixing characteristics of the mixer used to produce the energetic material directly affect the performance and production cost of the energetic material. At present, the mixing equipment suitable for energetic materials with high viscosity and high solid content is mainly a batch mixer, which has a large amount of mixing at one time, poor safety, high energy consumption, low operating efficiency, complicated process, and ...
