AI Technical Summary
Existing technologies are prone to dust leakage when dispersing powdered materials, which pollutes the environment and harms workers' health. At the same time, the dispersion efficiency is low, especially for ultralight materials such as aerogels, which are difficult to wet and disperse effectively.
A dust-free dispersion device is adopted, in which the powder is drawn into the premixing chamber by the pump and premixed directly with the liquid raw materials. The shearing teeth on the rotating disk and the fixed disk work together to shear and disperse the material, forming a circulation loop between the dispersion tank and the premixing chamber, ensuring that the material circulates repeatedly in the vortex mixing and forced shearing stages.
It achieves dust-free dispersion, improves the wetting and dispersion efficiency of powders, and is especially suitable for ultralight materials such as aerogels, ensuring that there are no dead corners in the material during shearing and improving the dispersion effect of the dispersion vessel.

[0023] Embodiments: As Figures 1-3 shown, Figure 1The arrow in the figure indicates the flow direction of the material, a dust-free dispersion device, comprising a dispersion kettle 100 and a solid-liquid mixing pump 200, the solid-liquid mixing pump 200 comprising a pump body 210 and a premixing chamber 220, an impeller 222 being arranged in the premixing chamber 220, the pump body 210 being connected to the impeller 222, the pump body 210 being capable of driving the impeller 222 to rotate to suck the powder into the premixing chamber 220 and then to transport the wetted powder into the dispersion kettle 100, the dispersion kettle 100 being provided with a stirring shaft 110 and a fixed disc 140, the stirring shaft 110 being fixedly provided with a rotating disc 120, the rotating disc 120 being provided with first shearing teeth 121, the fixed disc 140 being fixedly installed in the dispersion kettle 100, the fixed disc 140 being provided with second shearing teeth 141, the first shearing teeth 121 and the second shearing teeth 141 cooperating with each other to shear and disperse the material, a circulation loop being formed between the dispersion kettle 100 and the premixing chamber 220. That is, the material in the premixing chamber 220 can enter the dispersion kettle 100, and the material in the dispersion kettle 100 can also enter the premixing chamber 220. The pump body 210 is used to circulate and shear the material in the dispersion kettle 100 for multiple times until the material meets the requirements. The raw materials of the color paste product include powder and liquid, pigments, fillers, etc. being powder, including ordinary powder or ultra-light material aerogel powder, solvents, surfactants, dispersants, etc. being liquid, the powder raw material and the liquid raw material being connected to the premixing chamber through pipelines. When the pump body 210 drives the impeller 222 to rotate, a vacuum is formed in the premixing chamber 220 to suck the powder into the premixing chamber 220, the liquid flows into the premixing chamber 220 through the pipeline, the rotating impeller 222 premixes the powder and the liquid, and then the premixed material is pumped into the dispersion kettle 100 under the action of the pump body 210. The stirring shaft 110 in the dispersion kettle 100 rotates to break and shear the premixed material under the first shearing teeth 121 and the second shearing teeth 141, and the sheared material is circulated into the dispersion kettle 100 by the pump body 210 for multiple times to break and shear until the material meets the requirements and is discharged from the dispersion kettle 100.
[0024] The dispersion of powder includes three continuous processes, including the wetting of solid particles, the dispersion or breaking of particles, and the stabilization of solid particles, wherein the stabilization of solid particles mainly relies on the surface active agent or dispersant to maintain, and the dispersion efficiency of powder mainly relies on the wetting and dispersion or breaking of solid particles to improve the efficiency. In the prior art, such as ultra-light material aerogel, due to its hydrophobicity, it is difficult to wet even if it is put into the dispersion kettle, and it is more difficult to disperse or break faster. Even if the material is wetted, there may be grinding dead angles in the grinding process, and the phenomenon of uneven grinding and breaking occurs. Therefore, it is necessary to increase the grinding time to improve the uniformity of the particles, which makes the dispersion efficiency low.
[0025] In the application, the powder is directly sucked into the premixing chamber 220 by the pump body 210 to be premixed with the liquid raw material. The effect of dust-free mixing material is achieved, the wetting efficiency of the powder is improved, and the super-light material such as aerogel can be applied. The first shear teeth 121 on the rotating disc 120 and the second shear teeth 141 on the fixed disc 140 are matched to shear and crush the material. The material must be forced to shear and crush before entering the next cycle, so that the grinding has no dead angle, and the dispersion efficiency of the material is improved. The dispersion kettle 100 and the pump body 210 are matched to make the material circulate back and forth in the two stages of vortex mixing and forced shearing, so as to further improve the dispersion efficiency of the material.
[0026] Optionally, the first shear teeth 121 and the second shear teeth 141 are arranged in a radial direction of the dispersion kettle 100. The rotating disc 120 and the fixed disc 140 are arranged up and down in the dispersion kettle 100, the first shear teeth 121 and the second shear teeth 141 are radially staggered, and the first shear teeth 121 and the second shear teeth 141 jointly shear the material between the rotating disc 120 and the fixed disc 140. When shearing, the second shear teeth 141 are stationary, and the first shear teeth 121 rotate synchronously with the stirring shaft 110.
[0027] As shown in Figure 1 , the fixed disc 140 is fixedly installed on the inner side wall of the dispersion kettle 100, the fixed disc 140 is provided with a material leakage hole 142, and the rotating disc 120 and the inner side wall of the dispersion kettle 100 have a gap. Optionally, the material leakage hole 142 is coaxially arranged with the fixed disc 140. After the material enters the dispersion kettle 100 from the upper part of the dispersion kettle 100, it falls onto the fixed disc 140 through the gap between the rotating disc 120 and the inner side wall of the dispersion kettle 100. The stirring shaft 110 drives the rotating disc 120 to rotate, the rotating first shear teeth 121 and the stationary second shear teeth 141 force the material to shear and crush, and then the material falls through the material leakage hole 142.
[0028] As shown in Figure 2 and Figure 3As shown, the rotating disc 120 and the fixed disc 140 are both disc-shaped structures, the rotating disc 120 is provided with N circles of the first shear teeth 121, each circle of the first shear teeth 121 includes a plurality of the first shear teeth 121, and different circles of the first shear teeth 121 are located at different radial positions of the rotating disc 120, the fixed disc 140 is provided with N circles of the second shear teeth 141, and different circles of the second shear teeth 141 are located at different radial positions of the fixed disc 140, N≥2. Each circle of the first shear teeth 121 and each circle of the second shear teeth 141 are located at different radial positions of the dispersion kettle 100, and when shearing, each circle of the first shear teeth 121 moves in the gap between two circles of the second shear teeth 141, and the first shear teeth 121 are close to the fixed disc 140, and similarly, the second shear teeth 141 are close to the rotating disc 120.
[0029] Alternatively, the distance between two adjacent circles of the first shear teeth 121 is equal, the distance between two adjacent first shear teeth 121 in each circle is equal, the distance between two adjacent circles of the second shear teeth 141 is equal, and the distance between two adjacent second shear teeth 141 in each circle is equal. A plurality of circles of the first shear teeth 121 and a plurality of circles of the second shear teeth 141 form a labyrinth path, and the material is sheared and broken by the first shear teeth 121 and the second shear teeth 141 during flowing in the labyrinth path, thereby improving the dispersion effect of the material. In a possible implementation, as shown in Figure 2 and Figure 3 As shown, the rotating disc 120 is provided with 3 circles of the first shear teeth 121, and correspondingly, the fixed disc 140 is provided with 3 circles of the second shear teeth 141.

The material is sheared between the upper rotating disc and the upper fixed disc, and then enters the lower rotating disc and the lower fixed disc to be sheared and broken. Therefore, the material is sheared twice every time it passes through the dispersion kettle 100, thereby improving the dispersion efficiency and dispersion effect of the dispersion kettle 100.
[0031] Optionally, the distance between two adjacent first shearing teeth 121 in the upper rotating disc and the distance between two adjacent second shearing teeth 141 in the upper fixed disc are both L1, the distance between two adjacent first shearing teeth 121 in the lower rotating disc and the distance between two adjacent second shearing teeth 141 in the lower fixed disc are both L2, and L1>L2. The material is first sheared by the upper rotating disc and the upper fixed disc, and then sheared by the lower rotating disc and the lower fixed disc, so that the particle size of the material in the dispersion kettle 100 is gradually reduced, the load of each layer of shearing teeth is reduced, and the dispersion efficiency is improved.

[0035] The operation process of the dispersion device in the present application includes the following steps:
