Reaction kettle for titanium dioxide processing

Abstract

The invention relates to the technical field of titanium dioxide production and processing devices, in particular to a reaction kettle for titanium dioxide processing. The reaction kettle comprises a tank body and a grinding channel; a grinding assembly and a reaction cylinder are sequentially arranged in the tank body from top to bottom, the grinding assembly is composed of a plurality of grinding wheels, and the grinding wheels are regularly distributed in the tank body from top to bottom; the grinding wheel arranged at the upper end of the tank body is provided with a feed port for blank powder to enter the tank body, the grinding channel is arranged in the grinding wheel and located at the lower end of the feed port, the grinding channel is communicated with the feed port and arranged under the feed port, and the blank powder can do circular motion in the grinding wheel. By means of the reaction kettle, the feeding port is formed in the upper portion of the reaction kettle, when raw materials enter a barrel, blank materials can be crushed through the three grinding wheels in sequence, large raw materials can be prevented from falling off by forming second outlet holes with different sizes, meanwhile, the large raw materials can be pushed into an inclined groove again by a pressing rod for secondary crushing, and therefore possibility of caking of the raw materials entering the reaction barrel is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of titanium dioxide production and processing devices, in particular to a reaction kettle for processing titanium dioxide. Background technique [0002] Titanium dioxide is an important inorganic chemical product. It has important uses in coatings, inks, papermaking, plastic rubber, chemical fiber, ceramics and other industries. The main component is white pigment of titanium dioxide. The production process of titanium dioxide includes sulfuric acid method and chlorination. There are two kinds of process routes. [0003] In the existing production and processing methods, whether it is the sulfuric acid method or the chlorination method, it is necessary to use a separate reaction vessel for production. During the processing, the raw materials need to be put into the corresponding reaction kettle to allow the raw materials and reaction However, in actual use, the input raw materials often cause agglomeration ...

AI Technical Summary

Problems solved by technology

[0006] In view of the above-mentioned shortcomings existing in the prior art, the present invention provides a reaction kettle for processing titanium dioxide, which can effectively solve the problem in the prior art that titanium dioxide raw materials are easy to agglomerate, resulting in low output efficiency
