Description

Technical Field

[0001] The utility model belongs to the technical field of inclined tube sedimentation tanks, and particularly relates to a modular inclined tube sedimentation tank which is convenient for cleaning and replacement. Background Technique

[0002] In the inclined tube sedimentation tank, the inclined tubes are neatly welded and arranged on the sedimentation tank grid and fixed by ropes or steel bars. The inclined tubes are mainly made of polypropylene (PP). Compared with the ordinary sedimentation tank, the inclined tube sedimentation tank can greatly improve the sedimentation effect. However, the inclined tube sedimentation tank also has some disadvantages: the inclined tubes in the inclined tube sedimentation tank are prone to blockage while increasing the interception and sedimentation effect. Since the inclined tubes are immersed in water and fixed by ropes or steel bars, sludge is easily blocked in the inclined tubes. If not removed in time, the sedimentation effect will be reduced, and the sludge fermentation and floating will affect the water quality. Moreover, the inclined tube units are tightly connected. Once deformation and collapse occur in one place, the inclined tubes in other areas will be squeezed, which is likely to cause large-area deformation and collapse, resulting in frequent replacement and generally requiring overall replacement, with relatively high operation and maintenance costs. Content of the Utility Model
