Description

Technical Field

[0001] This utility model relates to the field of auxiliary pressurization technology for microporous membrane filters, specifically an auxiliary pressurization filtration device for microporous membrane filters. Background Technology

[0002] Microporous membrane filters are devices commonly used for filtering liquids or gases. They utilize microporous membranes to remove suspended particles, microorganisms, or other contaminants from water or gases. The pore size of microporous membranes is typically between 0.1 micrometers and 10 micrometers, effectively trapping larger particles and bacteria. In the process of pressurizing liquids using microporous membrane filters, a pressure filtration device is usually used.

[0003] An existing auxiliary pressure filtration device for microporous membrane filters (authorization announcement number: CN213101629U) has the following defects: The above device accelerates the filtration speed of liquid and shortens the filtration time by assisting pressure. It can achieve filtration operation with relatively small force and is easy to operate. However, during the operation of pressurizing and filtering liquid, a certain temperature is usually generated, which can easily damage the membrane. It is necessary to cool it down in time to avoid the high temperature affecting the filtration effect of the filter. Therefore, this utility model is proposed. Utility Model Content
