Powder-liquid mixing machine

Abstract

The invention discloses a powder-liquid mixing machine which comprises a main shell, a liquid dispersing device, a powder conveying device and a mixing device; a liquid dispersing area and a powder-liquid mixing area are formed in the main shell; the liquid dispersing device is used for dispersing to-be-mixed liquid in the liquid dispersing area and enabling the dispersed to-be-mixed liquid to enter the powder-liquid mixing area; the powder conveying device is used for conveying to-be-mixed powder into the powder-liquid mixing area; and the mixing device is used for mixing the to-be-mixed powder entering the powder-liquid mixing area and the to-be-mixed liquid entering the powder-liquid mixing area and discharging the mixed powder and the mixed liquid. During use, to-be-mixed slurry is dispersed in the liquid dispersing area through the liquid dispersing device and then enters the powder-liquid mixing area, and to-be-mixed powder conveyed by the powder conveying device is mixed through the material mixing device, so that the effect that to-be-mixed liquid is dispersed firstly and then mixed with the to-be-mixed powder is achieved; and the technical difficulties of blockage and dispersity contradiction of high-viscosity mixed materials are overcome.

Description

technical field [0001] The invention relates to the technical field of solid-liquid mixing equipment, in particular to a powder-liquid mixer. Background technique [0002] At present, with the development of powder technology, more and more ultrafine powders need to be dispersed into a small amount of liquid to form a high-concentration and high-viscosity slurry. However, in high-concentration slurries, the content of liquid components is small, which makes it difficult to mix the powder and liquid evenly. Although some slurries have low solid content, their physical properties also lead to high viscosity. Therefore, it is extremely difficult for the equipment to disperse and mix it. [0003] In the existing solid-liquid mixing equipment, due to its unreasonable structural design, there are technical difficulties in high-viscosity mixing blockage and dispersibility contradictions, such as a Chinese patent (notification number: CN109772189A) disclosed a suitable for high-vis...

Problems solved by technology

However, in high-concentration slurries, the content of liquid components is small, which makes it difficult to mix the powder and liquid evenly. Although some slurries have low solid content, their physical properties also lead to high viscosity. Therefore, it is extremely difficult for the equipment to disperse and mix it

[0003] In the existing solid-liquid mixing equipment, due to its unreasonable structural design, there are technical difficulties in high-viscosity mixing blockage and dispersibility contradictions, such as a Chinese patent (notification number: CN109772189A) disclosed a suitable for high-viscosity materials The solid-liquid mixing equipment and the mixing method using the equipment, the slurry after the solid-liquid mixing is dispersed through the mixing and dispersing module to improve the dispersibility of the high-viscosity mixture, but this structure will lead to the dispersion of the discharge path of the mixed material , will be easily blocked due to the viscosity of the high-viscosity mixture; another example is a solid-liquid mixing device disclosed in a Chinese patent (notification number: CN207203871U), which mainly disperses and / or pulverizes the powder through the powder dispersion module before entering the Mixed with the liquid to be mixed, if this structure is applied to the solid-liquid mixing of high-viscosity mixtures, it will also be easily blocked due to the viscosity of high-viscosity mixtures, resulting in poor stability of the equipment

Therefore, the existing solid-liquid mixing equipment still needs room for improvement
