Abstract
The invention discloses a barium sulfate impurity removal device which comprises a barium sulfate reactor, a barium sulfate separator, a drying bin, a crusher, a screening chamber, a grinding modification device and a recovery device, the discharging opening is connected with the drying bin through a conveying belt; the drying bin is connected with the crusher through a conveying belt, barium sulfate powder is crushed and preliminarily screened by the crusher and then is conveyed to the screening chamber through the conveying belt for physical impurity removal, the screened barium sulfate powder is conveyed to the grinding and modifying device through the conveying belt by the screening chamber for grinding and modifying the barium sulfate powder, and finally the barium sulfate powder is conveyed to the recycling device for packaging and recycling. The barium sulfate reactor firstly performs chemical reaction on the barium sulfide solution and the sodium sulfate solution to obtain the barium sulfate solution, then the barium sulfate solution is crushed, screened and purified by a physical treatment method, and the barium sulfate powder is modified by a chemical treatment method, so that the structure of the barium sulfate powder is more stable, and storage is facilitated.
Description
technical field [0001] The invention belongs to the field of barium sulfate compound purification, and in particular relates to a barium sulfate impurity removal device and method. Background technique [0002] Barium sulfate, odorless, tasteless powder, density 4.25-4.5, decomposition temperature > 1600°C, soluble in hot concentrated sulfuric acid, almost insoluble in water, dilute acid, alcohol, water suspension solution is neutral to litmus paper, barium sulfate powder Due to its unique properties, it can be used as a filler in coatings, inks, papermaking, industrial plastics, rubber products and other industries. Adding barium sulfate powder in the coating can improve the gloss of the coating film, reduce the blooming of the coating film, not affect the physical and mechanical properties such as adhesion and elasticity of the coating film, improve the whiteness of the coating, and enhance the hardness of the coating film. It is a powder coating The most ideal filler....
