Description

Technical Field

[0001] The utility model relates to the technical field of mineral processing pipelines, in particular to an anti-vibration device for a vertical rubber pipeline used for sand settling in a hydrocyclone. Background Art

[0002] There are many large-scale nonferrous metal mines in China. The commonly used grading equipment are linear vibrating screens and hydrocyclone groups. The diameter of a single hydrocyclone is large and there are many of them. During the production process, a large amount of sediment will pass through the hydrocyclone sedimentation trough and pipeline back to the mill.

Due to the large diameter of the pipeline, the vertically installed pipeline cannot be effectively fixed. The pipeline will generate large vibration during operation.
