[0002] In June 2020, a mineral processing plant built a new low-powder recovery system. The coarse concentrate recovered from the recovery plant of the second pump station needs to flow by gravity through a Φ273mm pipe to a 1,000 cubic meter concentrate box. The total length of the gravity pipeline is 450 meters, of which the length of the large slope section is 78 meters, with a height difference of 37 meters and a slope angle of 29°. The coarse concentrate contains coarse particles, which cause great wear on the coarse concentrate pipeline. The -200 mesh content of the coarse concentrate is about 20%, which has a large scouring force on the pipeline, shortening the service life of the coarse concentrate pipeline. In addition, since the coarse concentrate pipeline is laid along the mountain and passes through railway bridges and culverts, daily maintenance and replacement are difficult.
[0003] Therefore, in summary, it is necessary to provide a new type of force dissipation device to solve the shortcomings of the prior art. Utility Model Content
