Description

Technical Field

[0001] The utility model relates to the technical field of sodium pyrosulfite processing devices, in particular to a sodium pyrosulfite screening device. Background Art

[0002] Sodium metabisulfite, also known as sodium bisulfite, is an important chemical raw material and is widely used in many industrial fields, including the preparation of detergents, bleaches, paints, pulp and leather.

[0003] For the screening process of sodium metabisulfite, traditional screening devices usually have some defects. Since sodium metabisulfite is easy to agglomerate, traditional screening devices need to crush it before screening, which increases the complexity and time consumption of screening and affects production efficiency. In addition, after the screening is completed, the impurities remaining on the screen plate are not easy to clean, and the screen plate usually needs to be removed for cleaning, which is troublesome.
