[0002] Sodium antimonate, also known as sodium pyroantimonate, is the sodium salt of antimonous acid. Sodium antimonate is a white powder, soluble in tartaric acid, concentrated sulfuric acid, etc., slightly soluble in alcohol and ammonium salts, insoluble in acetic acid, dilute alkali and dilute inorganic acids, insoluble in cold water, and undergoes hydrolysis in hot water to form a colloid. It is used as an opaque filler, an opacifying agent for enamel, and an acid-resistant paint for iron sheets and steel plates. It is used as a glass clarifying agent and can also be used as a flame retardant synergist.

[0003] With the continuous development of sodium antimonate, sodium antimonate has been widely used in industrial flame retardants such as textiles, plastics, and rubbers; it can also be used in enamel and acid-resistant ceramics, high-grade ceramics. Currently, the domestic and foreign demand for it is increasing day by day. There are various existing production methods for sodium pyroantimonate. In China, the production of sodium pyroantimonate mainly uses the wet method. However, the existing sodium nitrate is in the form of massive solid particles.

Before stirring, the sodium pyroantimonate particles can be ground first, enabling them to be ground into powder and facilitating better reaction with the solution. Through the setting of the pneumatic assembly 3, external air can be sent to the aeration plate 301, causing the solution to turn under the action of the bubbles, thereby accelerating the reaction time between sodium pyroantimonate and the solution. Through the setting of the filtering assembly 4, the air entering the kettle body 1 can be filtered, preventing external impurities from contaminating the production of sodium pyroantimonate.
