Description

Technical Field

[0001] The utility model relates to the field of liquid-solid stirring beds, in particular to a fluid circulation device in a liquid-solid stirring bed which is convenient for observation. Background Art

[0002] A liquid-solid stirred bed is a device used to mix liquids and solid particles. Its structure usually consists of a stirring container, an agitator, a driving device and a supporting structure. Through reasonable design and operation, the liquid-solid stirred bed can achieve efficient mixing effects and improve production efficiency and product quality.

[0003] In a liquid-solid stirred bed, the suspended state of particles is affected by their size. Generally, smaller particles are more likely to suspend in the liquid flow field because of their relatively large surface area and greater liquid drag. For particles of the same density, the smaller the particle size, the greater the influence of fluid drag, and the easier it is to flow with the liquid and be more evenly distributed throughout the bed.

[0004] During the stirring process of the existing liquid-solid stirred bed, it is difficult to ensure the stable circulation of the fluid and the uniform dispersion of the solid particles due to the limitations of factors such as the agitator design, operating conditions and fluid mechanics characteristics. This causes the particles in the bed to easily settle and aggregate, affecting the stirring effect and product quality. Even if there is a circulating flow, the traditional stirred bed lacks a structure that is convenient for observing the internal fluid circulation state, making it impossible for operators to intuitively understand the fluid dynamics characteristics in the stirred bed, making it difficult to effectively control and optimize it.
