Abstract

The invention discloses a feeding device for a boiling chlorination furnace for producing titanium dioxide by chlorination. The feeding device comprises three feed bins, three weighing machines, three screens, a conveyor and a mixing spiral machine, wherein the three weighing machines are respectively and correspondingly connected with three feed bins by feeding pipelines; each screen is arranged in the corresponding feeding pipeline and is positioned between the corresponding weighing machine and the corresponding feed bin; each feeding pipeline is provided with an operation opening which is close to the corresponding screen and can be opened and closed; an outlet of the conveyor is communicated with the boiling chlorination furnace; the mixing spiral machine is arranged between the weighing machines and an inlet of the conveyor. According to the feeding device for the boiling chlorination furnace for producing the titanium dioxide by chlorination, which is disclosed by the embodiment of the invention, the feeding quantity is accurate, materials are uniform to mix, and the materials are smooth and continuous to feed, so that the stable and continuous operation of the feeding device is ensured, product quality is improved, and a boiling state of the boiling chlorination furnace is improved; meanwhile, the filtered materials are more uniformly mixed in the mixing spiral machine, so that layering of the materials entering the boiling chlorination furnace is avoided.

Description

technical field [0001] The invention relates to the technical field of titanium dioxide production by a chlorination method, and more particularly relates to a feeding device for a boiling chlorination furnace for titanium dioxide by a chlorination method. Background technique [0002] In the production of slag-discharging ebullient titanium dioxide chloride, the raw materials are mainly high-titanium slag, rutile and petroleum coke, which react with chlorine gas in the boiling state in the ebullient chlorination furnace. The boiling state of the fluidized furnace in the related art is poor, the material is prone to stratification in the fluidized furnace, the product quality is poor, and the problem of gas return often occurs during production operation, and the safety is low. Contents of the invention [0003] This application is based on the inventor's discovery and recognition of the following facts and problems: [0004] In the process of production, transportation a...
