Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, and in particular to a chemical liquid storage tank. Background Art

[0002] Storage tanks are sealed containers for storing liquids or gases. In terms of cost-effectiveness, steel-lined polyethylene storage tanks are the most advantageous.

In actual use, although the existing storage tanks can realize basic storage functions, they generally do not have the function of protecting the observation window. If the operator accidentally touches the observation window with a sharp object in his hand, the observation window will be broken, which will cause the chemical liquid to leak and affect the normal use of the storage tank. Therefore, it is necessary to improve it. Utility Model Content
