Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to an environmentally friendly underwater filter used in dredging engineering. Background Art

[0002] In dredging projects, a cutter suction dredger uses its cutter head to loosen the soil on the riverbed or seabed during dredging operations, causing sediment disturbance. A trailing suction dredger is equipped with a mud tank. During construction, in order to increase the loading capacity of the mud tank, low-concentration mud will overflow from the overflow tube. In other words, in addition to causing sediment disturbance, a trailing suction dredger will also have an overflow process. Larger sediment disturbances or mud tank overflows will cause a large amount of suspended matter to appear in the water body, which will spread under the influence of dynamic factors such as tides, affecting the environmental quality of the water body and posing a threat to the aquatic ecosystem.

[0004] In the prior art, a filtering device is added, which effectively solves the problem that large sediment disturbances or mud tank overflows will cause a large amount of suspended matter to appear in the water body, and spread under the influence of dynamic factors such as tides, affecting the environmental quality of the water body and posing a threat to the water ecosystem. However, the silt left behind by the filtration will inevitably remain in the filter screen. After a long period of filtration, the overall filtration effect will be greatly reduced.
