Description

TECHNICAL FIELD

[0001] The utility model relates to material mixing technical field, especially a kind of acoustic resonance mixer and device for non-magnetic material mixing. BACKGROUND

[0002] Resonant Acoustic Mixing (RAM) technology is a kind of efficient paddle-free mixing technology, which is suitable for mixing of various material systems, including solid-solid, solid-liquid, liquid-liquid and liquid-gas. This technology generates high-intensity vibration through resonance, excites low-frequency and high-acceleration acoustic waves in multiphase flow, and realizes uniform dispersion of materials. It has been widely used in many fields such as chemical industry, food, medicine, etc.

[0003] When the existing acoustic resonance mixing device mixes a plurality of materials with large differences in density, particle size, humidity and other characteristics, the water content and viscosity of the materials will affect their flowability and adhesion, thereby affecting the mixing effect and causing the mixed material to form lumps or be unevenly mixed. For example, materials with high humidity may be more likely to form lumps, while dry materials may not be easily mixed due to static electricity; high-viscosity materials may form sticky clumps during mixing, which may not be easily broken, resulting in uneven mixing; materials with poor flowability may not move easily during mixing, resulting in uneven mixing. Therefore, a medium-assisted acoustic resonance mixing technology has been proposed, which adds spherical medium for auxiliary mixing in acoustic resonance mixing. Under the action of acoustic resonance, the random movement of spherical mixing medium produces strong shearing action, which fully breaks up and disperses the difficult-to-disperse substances, thereby solving the problems of lumping and clumping of low-flowability and high-viscosity materials during mixing. However, this method requires medium screening and collection of mixed materials after mixing is completed, such as separation through a screen, which increases the process of obtaining mixed materials, increases dust in the screening environment, damages the health of operators, and there is a risk of contaminating the mixed materials during screening.
