Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a sediment processing device for water conservancy projects. Background Art

[0002] During the construction of water conservancy projects, sediment treatment is an unavoidable issue. Sediment treatment devices are the optimal solution for this task. These devices are classified into various types based on their operating principles and structural features, including spiral sediment separators, hydrocyclones, and centrifugal sediment separators. Of these, spiral sediment separators are popular due to their small footprint, wide applicability, simple structure, and ease of operation.

[0003] The principle of the spiral sediment separation device is mainly based on the physical gravity sedimentation and mechanical spiral lifting effect. The spiral shaft inside the device rotates and lifts the sediment sediment at the bottom upward along the bottom of the inclined spiral groove. At this time, the water in the sediment slurry flows back to the bottom through the gap of the spiral groove, while the solid particles gradually dry up and are eventually discharged at the discharge port. However, since some sediment blocks are large, they block the gap and cannot pass through the slurry water, resulting in poor separation effect; and the sediment blocks cannot be finely separated, and the solid particles can only be coarsely separated and discharged completely, resulting in the possibility of subsequent fine separation of sediment blocks; at the same time, due to the reflux of slurry water, the water at the bottom becomes more and more, causing some fine sand particles or mud particles to dissolve in water and unable to be separated, resulting in poor separation effect. Based on the above situation, the utility model provides a sediment treatment device for water conservancy projects to solve the above problems. Utility Model Content
