[0002] Sodium stannate is a colorless hexagonal plate-like crystal or white powder. It is soluble in water, and its aqueous solution is alkaline with a relative density of 1.438. It is insoluble in alcohol and acetone. When heated to 140°C, it loses its water of crystallization and becomes anhydrous. It absorbs carbon dioxide in the air and forms sodium carbonate and tin hydroxide. Impurities often float to the top of the liquid, requiring a dedicated sodium stannate impurity filter to remove them.

[0003] However, the existing sodium stannate impurity filtering device is inconvenient to clean and replace the corresponding filter element after filtration, and it is very troublesome to disassemble and assemble. Moreover, it is not easy to clean the inside of the device after long-term use, resulting in unsatisfactory filtering effect. Utility Model Content
