Description

Technical Field

[0001] The present invention relates to the technical field of titanium dioxide processing, and particularly relates to a coating device for titanium dioxide production. Background Art

[0002] Titanium dioxide is a non-toxic and odorless white inorganic pigment, with good whiteness, opacity, covering power, light chromaticity and other characteristics. It is the best white pigment that cannot be replaced so far. The main component of titanium dioxide is TiO2. When irradiated by ultraviolet light, TiO2 undergoes a photocatalytic reaction to produce hydroxyl radicals or peroxyhydroxyl radicals, which have high activity and can catalytically degrade the surrounding organic media, causing the organic matter to break chains, degrade, etc., resulting in a series of changes such as the material turning gray, yellowing, and powdering. Wet coating can coat hydrated oxides such as silicon, phosphorus, aluminum, and zirconium on the surface of TiO2, forming one or more layers of "blocking films" on its surface, reducing the degradation of organic substances by free radicals, and improving the application performance of titanium dioxide in coatings, plastics, etc.

[0003] For example, the invention with the publication number CN116328635A provides a coating device for the production of super-dispersed titanium dioxide, including a tank body. The tank body is provided with a motor, and the motor is drivingly connected to stirring teeth; a feeding mechanism is arranged at the top of the tank body. The feeding mechanism atomizes the coating agent and pressurizes the atomized coating agent, and quickly sends it into the titanium dioxide solvent through a hollow tube and a dispersion plate to fully react with titanium dioxide to achieve coating; it also includes a temperature adjustment unit. Through the temperature adjustment unit, when the temperature in the tank body rises, the liquid flow rate in the water bath tube is increased to quickly take away the excess heat, which is beneficial to maintaining the constant temperature of the tank body and ensuring the stable progress of coating; it promotes the full contact between the coating agent and the titanium white slurry, improves the coating efficiency, and increases the uniformity and dispersion of the titanium dioxide coating.

[0004] The existing technology has the following problems: When the existing coating device for titanium dioxide production coats titanium dioxide, it is necessary to first dissolve titanium dioxide into titanium white slurry, and it takes a lot of time to stir and dissolve titanium dioxide with another device, which affects the subsequent coating efficiency of titanium dioxide. And short-time stirring is likely to cause titanium dioxide to agglomerate, affecting the coating quality of titanium dioxide. Moreover, when the existing device stirs the titanium white slurry and the coating agent, the stirring structure mostly rotates in one direction in the main body, which will make the raw materials stirred unevenly, resulting in uneven coating of titanium dioxide and affecting the stability of the coated titanium dioxide.

[0005] Therefore, a coating device for titanium dioxide production is proposed. Summary of the Invention
