[0002] Hydrochloric acid solution refers to an aqueous solution of hydrogen chloride, which has a wide range of industrial uses. Hydrochloric acid is a colorless, transparent liquid with a strong pungent odor and high corrosiveness. Concentrated hydrochloric acid (mass fraction of about 37%) is extremely volatile. Hydrochloric acid can be used for pickling steel and is also a chemical reagent required for large-scale preparation of many inorganic and organic compounds, such as vinyl chloride, the precursor of PVC plastics. Hydrochloric acid also has many small-scale uses, such as household cleaning, production of gelatin and other food additives, descaling agents, leather processing, etc. Hydrochloric acid solution is stored in a special storage tank. The existing hydrochloric acid solution tank has the disadvantage of not having a metering function when in use. People cannot accurately know the liquid level in the tank, which makes it inconvenient for workers to add solution to the inside of the tank. There are limitations in use and there is room for improvement. Utility Model Content
