Description

technical field [0001] The invention belongs to the related technical field of multiphase flow mixing, and more specifically relates to a two-mass acoustic resonance mixing device suitable for composite energetic materials. Background technique [0002] Due to the limitations of shear sensitivity, temperature rise sensitivity and extrusion sensitivity, composite energetic materials are difficult to mix at high shear rates. Under the condition of low shear rate, due to the small content of liquid components, the fluidity of the material is poor, and the material is mixed in a laminar flow state, which makes it difficult to achieve a superior mixing effect. Existing mixing technology mainly achieves dispersion through shearing of mixing elements (such as paddles or screws) and materials. Increased production risk. Therefore, the traditional mixing method can no longer meet the development requirements of high quality, high efficiency and high safety for the mixing of composi...

Problems solved by technology

However, the current three-degree-of-freedom acoustic resonance mixing device has high complexity, poor system stability, and difficult vibration stability control; at the same time, the structure of the three-degree-of-freedom acoustic resonance mixing device is complex, and the maintenance cost and manufacturing cost are high.

When the single-mass resonance mixing device is used, since the single-mass resonance mixing device has no vibration isolation spring, the dynamic load transmitted to the foundation is relatively large, and the use is limited

At present, most acoustic resonance mixing equipment does not seal the internal structure of the mechanical system. Dust and liquid can easily enter the mechanical system, causing system failure and damage. What is more serious is that energetic powder enters the mechanical system. Due to friction and collision It is very likely to cause an explosion
