Description

Technical Field

[0001] The present application relates to the field of industrial automation technology, and in particular to an automatic feeding system for a sodium sulfate recovery station. Background Art

[0002] Sodium sulfate recycling stations recycle waste sodium sulfate liquid and regenerate it. Currently, the manual dosing process used by these stations is relatively outdated. This process requires manually adding solid sodium hydroxide and solid sodium bisulfite to the raw material tank.

[0003] Because solid sodium hydroxide is not easily soluble in water, the raw material tank needs to be steam-heated, requiring workers to add the material under high-temperature conditions. Furthermore, the large amount of heat generated when sodium hydroxide dissolves in water can cause the sodium hydroxide liquid to splash out of the raw material tank, resulting in skin burns for workers. Furthermore, when adding solid sodium bisulfite manually, the raw material tank needs to be heated with steam to increase its solubility. This manual addition process can easily cause the sodium bisulfite solid to spill and lower the temperature of the liquid in the raw material tank, resulting in a waste of resources and environmental pollution.

[0004] In view of the above-mentioned related technologies, the inventors believe that the existing manual feeding has problems such as a harsh working environment for workers, poor safety, easy spillage of raw materials and environmental pollution. Utility Model Content
