Description
Technical Field
[0001] The utility model relates to the technical field of preparation of antimony trioxide, in particular to an antimony trioxide purification dryer. Background Art
[0002] Antimony trioxide is an inorganic compound with the chemical formula Sb2O3. The natural product is called antimony flower, commonly known as antimony white. It is a white crystalline powder with a melting point of 655℃ and a boiling point of 1550℃. It is soluble in concentrated hydrochloric acid, sulfuric acid, alkaline solution and hot tartaric acid solution, slightly soluble in water, dilute nitric acid and dilute sulfuric acid. It is mainly used as a pigment, flame retardant, mordant, catalyst, and can also be used to synthesize antimony salts. When producing antimony trioxide, it needs to be extracted by purification and drying. The crude antimony ore is added to hydrochloric acid for impregnation, chlorine is introduced, and iron powder is added to the obtained antimony chloride mixed solution to react to obtain antimony chloride solution; then an appropriate amount of 4mol / L sodium hydroxide solution is added, the pH value is 8-9, stirred and filtered, washed, dried, and roasted in an air atmosphere to obtain antimony trioxide; antimony trioxide is vaporized into liquid, compressed air and a composite lead remover are introduced, and the obtained antimony trioxide powder is vaporized and quenched to obtain high-purity antimony trioxide.
[0003] Then, when antimony trioxide is produced, a purification dryer is needed. The purification dryer places the treated solution inside a sealed tank, and uses a heating and stirring device to drive the impurities and liquid in the solution to precipitate, and then the antimony trioxide can be purified. However, during the antimony trioxide treatment process, the reactants and antimony trioxide need to be mixed with each other as needed, and sodium hydroxide solution is added in sequence according to the reaction state of antimony trioxide to improve the purification efficiency of antimony trioxide. However, when controlling the reactant conveying and drying inside the device, the active stirring tank will be affected, thereby reducing the purification efficiency of antimony trioxide. For this reason, we propose an antimony trioxide purification dryer. Utility Model Content
