[0021] (III) Beneficial Effects

[0022] Compared with the prior art, this utility model has the following advantages:

[0023] While existing polyether polyol storage tanks offer convenient storage and allow for stirring to prevent sedimentation, and facilitate easy cleaning by lifting, they suffer from several drawbacks. Firstly, the rotating wrench protrudes from the outside of the tank, resulting in an uneven top that hinders stacking. Secondly, the repeated lifting and cleaning method increases labor intensity and requires additional water for efficient cleaning. The cleaning process for polyether polyol storage tanks is often cumbersome and inefficient. This invention addresses this issue by installing a rotating, sealed lid at the top of the tank. This design ensures the tank remains level while maintaining its stirring function, facilitating convenient stacking during use. Furthermore, a water storage chamber is provided within the lid, with spray nozzles evenly distributed below. This allows for automatic cleaning of the tank interior simply by applying high pressure through the inlet pipe, reducing manual cleaning labor and significantly improving cleaning efficiency.
