Technical Field

[0001] This utility model relates to the field of water purification device technology, and in particular to an integrated ultrafiltration membrane water purification device with automatic backwashing function. Background Technology

[0002] In today's water purification and treatment field, integrated ultrafiltration membrane water purification devices play a crucial role. Leveraging the unique filtration performance of ultrafiltration membranes, they effectively trap large molecules such as suspended solids, colloids, proteins, and microorganisms in water, allowing only solvents, inorganic salts, and small organic molecules to pass through. This achieves water purification and separation, making them widely applicable in various water purification scenarios and providing key support for ensuring safe drinking water.

[0003] To address this, Chinese patent number CN222454658U proposes an integrated pressure-type submerged ultrafiltration membrane water purification device. This device can use a water pump to draw water from the backwash tank into the tank to rinse the hollow fiber membrane. However, it cannot flexibly adjust the rinsing range according to the actual fouling of the filter membrane, resulting in dead zones. This affects the cleaning effect and service life of the filter membrane, making it inconvenient to use. Utility Model Content
