Description

Technical Field

[0001] The utility model relates to a caustic soda storage tank which is convenient to clean, and belongs to the technical field of caustic soda storage tanks. Background Technique

[0002] Caustic soda is an inorganic compound with strong alkalinity and extremely strong corrosiveness. It can be used as an acid neutralizer, complexing masking agent, precipitant, precipitation masking agent, chromogenic agent, saponifying agent, skin peeling agent, detergent, etc., and has a very wide range of uses. Due to the strong alkalinity and strong hygroscopicity of caustic soda, it is easily soluble in water, releases heat when dissolved, the aqueous solution is alkaline, and has a slippery feeling; it is extremely corrosive and has a corrosive effect on fibers, skin, glass, ceramics, etc., so caustic soda needs to be stored in a special storage tank.

[0003] For example, CN216582165U discloses a high-strength caustic soda storage tank. By rotating the rotating feet, the cylinder can be conveniently tilted to pour out the caustic soda inside the cylinder.

[0004] As can be seen from the above, the storage tank can be rotated and tilted for discharging materials during use. However, after the raw materials in the storage tank are poured out, certain material residues are likely to remain inside the storage tank. Due to the high height and depth of the storage tank, it is inconvenient to clean the inside of the tank body. If personnel enter the inside of the storage tank for cleaning, not only is the efficiency low, but also there is a certain danger. Therefore, optimization and improvement are needed.
