Description

Technical Field

[0001] The utility model belongs to the technical field of titanium dioxide production, and in particular relates to a coating tank. Background Art

[0002] Titanium dioxide is the best white pigment. It has the advantages of high whiteness, high opacity, and stable physical and chemical properties. It is widely used in coatings, plastics, papermaking and other industries. In the process of producing titanium dioxide, titanium dioxide will be coated, which is divided into inorganic coating method and organic coating method. Inorganic coating refers to adding inorganic treatment agents to the titanium dioxide slurry, and making its metal ions deposited on the surface of titanium dioxide particles in the form of oxides or hydroxides to reduce photochemical activity and improve weather resistance; organic coating refers to adding organic treatment agents to the titanium dioxide slurry, which are adsorbed on the surface of titanium dioxide particles in the form of physical adsorption and chemical adsorption, changing the surface properties of titanium dioxide to improve the dispersibility of titanium dioxide in different media.

[0003] Titanium dioxide is produced using the sulfuric acid method. In the post-processing section, i.e. the coating section, titanium dioxide ions are subjected to inorganic treatment to improve the weather resistance, durability and chemical stability of titanium dioxide. During the inorganic coating treatment, aluminum sulfate and sodium aluminate need to be added to the titanium dioxide through aluminum sulfate pipelines and sodium aluminate pipelines. Since aluminum sulfate is acidic and sodium aluminate is alkaline, the distance between the aluminum sulfate pipeline and the sodium aluminate pipeline determines the degree of acid-base reaction between aluminum sulfate and sodium aluminate. The stronger the acid-base reaction, the worse the quality of the titanium dioxide coating. Therefore, the coating quality can be adjusted by adjusting the distance between the aluminum sulfate pipeline and the sodium aluminate pipeline, which can reduce ineffective coating agents and reduce material transfer time.

[0004] When adjusting the distance between the aluminum sulfate pipeline and the sodium aluminate pipeline, the existing coating tank cannot adapt to the change in the distance between the aluminum sulfate pipeline and the sodium aluminate pipeline, resulting in inconvenience in adjustment and reduced efficiency.
