AI Technical Summary
In the prior art, the agitator entrains a large amount of air into the slurry during the mixing process, causing air bubbles to form and resulting in slurry stratification.
A slurry dispensing device for preventing stratification was designed. It uses a sealing cover and a lifting adjustment component. The sealing cover slides down the inner wall of the dispensing container to squeeze out air, and the pressure relief component discharges excess gas, thereby reducing the amount of air entrained by the agitator and preventing the formation of bubbles.
It effectively reduces the number of air bubbles in the slurry, avoids slurry stratification, and ensures the uniformity and stability of the slurry.
