Abstract

The invention discloses a continuous feeding device for scab removing sand and a titanium dioxide production device adopting a chlorination process. The continuous feeding device for scab removing sand comprises a feeding tank, a jetting tank, and a feeding spiral device, wherein the feeding tank is arranged downstream a feeding device; a first tank lock for connecting and disconnecting the feeding device and the feeding tank is arranged between the feeding device and the feeding tank; a sensor for detecting the quantity of materials is arranged on the feeding tank, and is electrically connected with the first tank lock; the jetting tank is arranged downstream the feeding tank; a second tank lock for connecting and disconnecting the jetting tank and the feeding tank is arranged between the jetting tank and the feeding tank; the feeding spiral device is arranged downstream the jetting tank and provided with a material outlet. According to the continuous feeding device for scab removing sand, provided by the embodiment of the invention, scab removing sand can be jetted into an oxidation reactor continuously to remove titanium oxide scabs on the inner wall of the oxidation reactor, so that the normal and stable operation of a titanium oxide oxidation system under the situation of uniform heating is guaranteed.

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] Titanium chloride oxidation in the production process of titanium dioxide by chloride method is a key step in the preparation of titanium dioxide. Titanium oxide scabs are prone to occur during the oxidation process of titanium chloride, which affects the normal and stable production process of titanium dioxide. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention needs to provide a continuous feeding device for scar removal sand, which can continuously add scar removal sand into the oxidation reactor, and solves the problem of titanium oxide scarring in the production ...
