Description
Technical Field
The utility model relates to a material mixing technical field especially relates to an impeller subassembly and solid-liquid mixing equipment.
Background
In the industrial field, many liquid raw materials are prepared by mixing powders and liquids, and especially, ultra-fine powders such as nano-sized powders are mixed and dispersed in a small amount of liquid or mixed and dispersed into a high-viscosity mixed liquid, such as slurry applied to the positive and negative electrode fields of lithium ion batteries. Generally, the entire mixing process can be divided into three stages, break up, wet and disperse. In the scattering step, the powder is stirred from the large agglomerates by a stirring blade or the like to be in a substantially powder state.
In the infiltration stage, the powder is in contact with the liquid, but with the development of powder technology and nanotechnology, the specific surface area of the powder is obviously increased, a large amount of gas can be adsorbed on the surface of the powder, and in the process of dispersing the ultrafine powder into a small amount of liquid to form high-viscosity slurry, the powder particles are difficult to be fully infiltrated with the liquid, the distribution of the powder particles in the liquid is also very uneven, and even agglomeration and the like can occur.
In the dispersing stage, the suspension after infiltration or premixing is dispersed again, so that the distribution consistency of the powder particles in the suspension meets the production requirement. At this stage, the dispersion of lumps, etc. possibly present in the suspension is accomplished mainly by means of strong shear forces, and the powder particles are uniformly driven into all the liquids involved in the mixing. However, since the requirements of the infiltration and dispersion processes on the mixing equipment are not consistent, in this case, a single mixing mode cannot achieve a good mixing effect, in the prior art, the infiltration process of the powder and the liquid and the dispersion process of the powder in the liquid are respectively completed by using special equipment, so as to achieve a better mixing effect.
The soaking and the dispersing are respectively carried out by two sets of independent equipment, the soaking is carried out after the scattering, then the scattering is carried out by transferring to the next equipment, and the pulping efficiency of the operation mode is lower.
Therefore, an impeller assembly and a solid-liquid mixing apparatus are needed to solve the above technical problems.

Because the centrifugal force at the bottom of the impeller is larger, the air bubbles on the surface of the material can be broken and emptied. And the materials can be fully dispersed through the shearing of the first perforated plate and the second perforated plate. Because the impeller can rotate for first perforated plate and first perforated plate rotates for the second perforated plate, can make the shearing force that the material receives bigger, make the material obtain more abundant dispersion.
