Description

Technical Field

[0001] This utility model relates to the field of defoamer technology, specifically to a defoamer sealing and shearing device. Background Technology

[0002] Defoamers are chemical substances that reduce or eliminate foam in liquids by disrupting or inhibiting foam formation. They are widely used in industry, agriculture, and daily life. Surfactants in liquids reduce the surface tension of water, forming a thin film of bubbles. When air enters the liquid, it is trapped in the film, and multiple bubbles aggregate to form stable foam. Defoamers spread rapidly on the foam surface, replacing the original surfactants, reducing the strength of the liquid film, and causing the foam to break. Some defoamers, such as hydrophobic dimethyl silicone oil, can prevent air from entering the liquid, reducing foam generation at the source.

[0003] In the prior art, defoamers need to maintain their defoaming effect stably under high shear force environments, such as mechanical stirring, fluid impact, and pumping. To achieve this, it is necessary to quickly break down the foam through physical or mechanical means, reduce the chemical dependence of the defoamer, or improve its shear resistance. Therefore, we propose a defoamer sealing shearing device. Utility Model Content
