Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ultrafiltration machine with an inclined cylindrical shape. Background Technology

[0002] The circulating centrifugal wastewater drum filter utilizes a high-speed rotating centrifugal mechanism to generate powerful centrifugal force, rapidly separating solid particles and sediments from wastewater and concentrating them within the centrifuge's relative gravitational field, thus achieving rapid and efficient wastewater treatment. In current centrifugal filtration equipment, when a large amount of dirt and sediment accumulates inside the filter cartridge, it easily clogs the cartridge wall, affecting the filtration effect. Later maintenance requires disassembling the entire machine, which is very complex and cumbersome. Furthermore, wastewater only passes through the filter cartridge once; as the machine is used, its filtration efficiency gradually decreases. Utility Model Content
