Description

Technical Field

[0001] The utility model relates to the technical field of titanium dioxide processing, in particular to a hydrolysis mixer for titanium dioxide production. Background Art

[0002] Titanium dioxide is an important inorganic chemical pigment, the main component of which is titanium dioxide. There are two production processes for titanium dioxide: sulfuric acid method and chlorination method. The sulfuric acid method is to produce titanium dioxide sulfate by acid hydrolysis of ferrotitanium powder and concentrated sulfuric acid, which is then hydrolyzed to form metatitanic acid, which is then calcined and crushed to obtain titanium dioxide products. This method can produce anatase and rutile titanium dioxide. The advantages of the sulfuric acid method are that it can use cheap and easily available ilmenite and sulfuric acid as raw materials, the technology is relatively mature, the equipment is simple, and anti-corrosion materials are easy to solve.

[0003] In the existing titanium dioxide production process, a mixer is required to participate in the hydrolysis reaction of titanium dioxide to improve the hydrolysis efficiency of titanium dioxide. However, due to the fine particles of titanium dioxide and strong dispersibility, it is easy to disperse in the liquid medium and form a high-quality dispersion system. In the initial stage of stirring, before it is completely mixed, the solution concentration is high and relatively viscous. Some undissolved materials are blocked by the high-concentration materials and adhere to the inner wall of the stirring barrel, forming certain material protrusions, which affects stirring. In addition, titanium dioxide particles are relatively fine. When pouring directly into the stirring barrel during material discharge, more dust will be raised, causing material loss. In addition, the specific gravity of the titanium dioxide material package is relatively large, and direct pouring is more laborious. Utility Model Content
