Abstract

The invention discloses a continuous scab removal sand feeding device and a titanium white chlorination production device with the same. The continuous scab removal sand feeding device comprises a charging material tank with a charging hole, a pressure release valve and a sensor for detecting the material capacity, a middle material tank arranged at the downstream part of the feeding material tank, and a feeding material tank which is arranged at the downstream part of the middle material tank and is provided with a discharging hole, wherein a first discharging valve for connecting the charging material tank with the middle material tank and disconnecting the charging material tank from the middle material tank is arranged between the charging material tank and the middle material tank; a discharging adjustment device for adjusting the material conveying quantity is arranged at the discharging hole; a second discharging valve for connecting the middle material tank with the feeding material tank and disconnecting the middle material tank from the feeding material tank is arranged between the middle material tank and the feeding material tank. According to the continuous scab removal sand feeding device disclosed by the embodiment of the invention, the scab removal sand conveying quantity can be accurately adjusted, and scab removal sand can be continuously and stably discharged.

Description

technical field [0001] The invention relates to the technical field of industrial production of titanium dioxide, in particular to a continuous feeding device for removing scar sand and a production device for chlorinated titanium dioxide having the device. Background technique [0002] The existing production of titanium dioxide mainly includes sulfuric acid method and chlorination method. The sulfuric acid method is suitable for the production of anatase titanium dioxide, and the chlorination method is suitable for the production of high-grade rutile coating titanium dioxide. The proportion has exceeded 56%. Chlorination titanium dioxide process includes titanium-rich material chlorination, TiCl 4 (Titanium tetrachloride, titanium chloride) refined, TiCl 4 Oxidation and TiO 2 (Titanium dioxide, titanium dioxide) particle surface treatment four main processes, in which TiCl 4 Oxidation is the most critical step in the preparation of rutile titanium dioxide. [0003] Ho...
