Description

Technical Field

[0001] The utility model relates to the technical field of ultrafiltration devices, in particular to a water purification ultrafiltration device. Background Art

[0002] Ultrafiltration is one of the membrane separation technologies that uses pressure as a driving force. It aims to separate large molecules from small molecules, and the membrane pore size is between 20-1000A°. Currently, the existing ultrafiltration devices for water purification on the market mainly use ultrafiltration cartridges as the core components of filtration. Since most of the existing ultrafiltration devices cannot pre-treat water, large-volume impurities in the water are easily accumulated on the surface of the ultrafiltration membrane and cause blockage, resulting in a decrease in water production and an increase in equipment maintenance costs. Therefore, patent CN218421272U proposes "an ultrafiltration device for water purification". Through the setting of a water inlet bucket, a filter screen and a collection bucket, the transported water is preliminarily filtered through the filter screen, and large particles of impurities and debris can be removed in advance to avoid clogging the filter assembly. The collection bucket collects impurities for centralized treatment, which not only reduces the labor intensity of cleaning the filter assembly, but also extends the service life, thereby achieving the purpose of pre-treating the water.

[0003] However, in this solution, the filter screen is fixedly installed on the bottom inner wall of the collecting bucket, which increases the difficulty of disassembling the filter screen during subsequent cleaning and replacement, causing inconvenience to subsequent maintenance. Therefore, a water purification ultrafiltration device is proposed. Utility Model Content
