A rotary dredging device for anti-silting of pipelines

Abstract

The invention discloses a rotary dredging device for preventing pipeline silting, which comprises a long shaft (1), a blade shaft (2) and a shaft collar (3), the blade shaft (2) and the shaft collar (3) are sleeved on the periphery of the long shaft (1), the long shaft (1) is a stepped shaft with a through hole in the center, which is sequentially divided into a first shaft section (1-1), a second shaft section (1-2), a third shaft section (1-3), a fourth shaft section (1-4) and a fifth shaft section (1-5), and the first shaft section (1-1) is provided with elastic clamping plates; the diameter of the second shaft section (1-2) is equal to the diameter of the fifth shaft section (1-5), the diameter of the third shaft section (1-3) is less than the diameter of the second shaft section (1-2), and the diameter of the fourth shaft section (1-4) is greater than the diameter of the fifth shaft section (1-5). The structure design of the rotary dredging device for preventing pipeline silting is reasonable, the application range is wide, the applicability is high, the rotary dredging device for preventing pipeline silting not only does not affect the movement of semifluid in a pipeline, but also can prevent the solid of semifluid from silting the pipeline, and in particular, the silting prevention effect is more remarkable for nonlinear pipelines.

Description

Technical field [0001] The invention relates to an anti-siltation device for pipelines, in particular to a rotary dredging device used in various pipelines to prevent solids in semi-fluid from silting up. Background technique [0002] At present, the application of pipelines in daily life is very common. Pipes are generally used as fluid and semi-fluid pathways. They are effective for pure fluid pipeline transportation, but for semi-fluid transportation (such as semi-fluid delivery through pipelines in aquaculture). For feed (a mixture of water and feed), solids in the semi-fluid often accumulate in the pipeline, which affects the movement of the semi-fluid in the pipeline, and sometimes even causes the pipeline to block, especially the non-linear pipeline, where the siltation phenomenon is more serious. [0003] Therefore, it is necessary to research and develop a rotary dredging device with reasonable structural design on the basis of the existing technology, which does not affec...
