Description

Titanium dioxide handles back groove pressure relief device Technical Field The utility model belongs to the technical field of titanium dioxide production, and particularly relates to a pressure relief device for a titanium dioxide treatment rear groove. Background The production method of titanium dioxide mainly adopts a chloridizing method and a sulfuric acid method to produce titanium dioxide in China, but the production of titanium dioxide is divided into pretreatment production and post-treatment production no matter the chloridizing method or the sulfuric acid method, the pretreatment production mainly comprises the steps of titanium ore reaction, purification to crude titanium dioxide, and post-treatment, the post-treatment mainly comprises the steps of grinding, surface treatment, washing, drying and jet milling, wherein the surface treatment is an inorganic coating process, the coating agent is added under the conditions of a certain temperature and a certain pH value to carry out inorganic coating, and more inorganic salts are also caused in slurry and need to be removed in the washing process. The washing process comprises the processes of feeding, back blowing, center washing, side first washing, side second washing, squeezing, back blowing, angle blowing and the like, wherein titanium dioxide generally passes through filter cloth along with water flow when a plate frame is not full in the feeding process, the titanium dioxide generally needs to be recovered, the part is generally transferred into a post-treatment tank to wait for reentry into a system, but because the feeding has pressure, and the plate frame is generally positioned on a higher floor, the water outlet pressure is generally higher, and a larger impact force exists when the plate frame is transferred into the post-treatment tank, and in the same way, the back blowing and the angle blowing are used for carrying out pressure blowing on the center hole and the upper and lower corners of the plate frame, and the higher pressure can blow out the titanium dioxide of the center hole and the angle hole, so that the part of the material is generally transferred into the post-treatment tank for recycling, but because of the higher pressure and the higher floor height, the impact force can cause vibration of the post-treatment tank and splashing of the material, the pipeline deformation leakage, the vibration screen damage, the material splashing and the like, and the problem that the material is required to be solved as soon as possible when the material is recovered.
