Industrial-grade ultrasonic mixers achieve uniform mixing of liquids, gases, and even suspended particles within solutions through the cyclic action of the agitator. To achieve this, the use of devices that induce forced convection and even mixing, i.e., the agitator, is necessary. Through mixing, reactants are thoroughly blended and heated evenly, shortening reaction time and enhancing yield.
Ultrasonic mixing, an important application of ultrasonic technology, involves dispersing and aggregating solids in liquids to achieve mixing. The high shear force generated by the cavitation of ultrasound is the driving force behind this process.
Theoretically, the mixing power can be divided into two aspects: the mixer power and the mixing operation power. However, in practice, it is generally only the mixer power that is considered, or primarily considered, due to the difficulty in accurately measuring the mixing operation power, which is usually achieved by setting the mixer's speed to meet the required mixing operation power. Starting from the concept of mixer power, the main factors affecting the mixing power are as follows.
1. The structure and operating parameters of mixers, such as the type of industrial-grade ultrasonic mixer, impeller diameter and width, impeller inclination angle, number of impellers, and the speed of the mixer.
2. Structural parameters of the mixing tank, such as: the internal diameter and height of the mixing tank, the presence of baffles or flow conduits, the width and quantity of baffles, and the diameter of the flow conduits.
3. Physical properties of the mixing medium, such as: densities of various media, viscosity of liquid phase media, size of solid particles, and gas medium ventilation rate, etc.
The analysis shows that the factors affecting the mixing power are complex, generally making it difficult to derive a calculation equation for mixing power through theoretical analysis alone. Therefore, resorting to experimental methods, combined with theoretical analysis, is the approach to obtaining the mixing power calculation formula.
