Choosing Model of Plastic Storage Tanks and Mixing Equipment: The diversity of mixing purposes, raw material characteristics, mixing mechanical methods, and the complexity of internal fluidity within the mixing equipment, make the selection and design of mixing machinery not solely achievable through careful theoretical innovation, but also depends on experience. The quality of the design can significantly affect the economic benefits of the mixer. Therefore, it is necessary to clearly define the mixing objectives and characteristics of the raw materials, such as impeller appearance, impeller diameter, impeller stacking layers, centrifugal impeller installation position, speed ratio, mechanical equipment type, baffle size and quantity, etc. Generally, the design sequence of mixing equipment is:

Establishment and confirmation of blending standards → Selection of blending centrifugal impeller type and internal components → Clarification of centrifugal impeller dimensions and speed ratio → Calculation of blending output power → Mechanical structure design of blending equipment

The blending standards to be set include the tanker's volume, tank type, characteristics of the material inside the tank, blending purpose, actual operating temperature and pressure, whether it's a batch operation or a continuous operation, etc. Undoubtedly, this is a prerequisite for designing blending machinery, typically provided by the client of the blending machinery. However, for some content, clients often cannot specify it precisely and need to communicate with the designer to understand it, especially for the material characteristics and blending purpose. For instance, for non-Newtonian fluids like polymer melt, the viscosity in the operating state is related to the shear rate, which in turn is related to the form and speed ratio of the blending equipment; also, for behaviors like solid-liquid floating, gas-liquid dispersion, etc., the blending machinery designer needs to clearly specify the required blending intensity levels. Yet, these levels often require harmonious communication between the designer and the user, ultimately leading to a verification of the blending standards.
