Slow descent pipeline

Abstract

The invention discloses a slow descent pipeline, and belongs to the technical field of conveying devices. The slow descent pipeline aims to solve the problem that material will impact the lower side of a vertical section and the lower side of an inclined section when falling off to cause abrasion of a pipe fitting. The slow descent pipeline comprises the vertical section and the inclined section which is connected to the lower portion of the vertical section, a plurality of inclined baffles are arranged in the vertical section in the longitudinal direction, and every two inclined baffles penetrate through each other. According to the slow descent pipeline, the inclined baffles are arranged in a staggered mode to form a zigzag curve flowing channel. When the slow descent pipeline works, the material enters the vertical section from the upper portion, makes contact with the inclined baffle on the upper portion, reverses, descends step by step after being buffered, and is conveyed to other areas from the inclined section. Compared with the prior art, the inclined baffles of the slow descent pipeline have a slow descent effect on material flow, abrasion to the pipe fitting from the fallen material can be effectively slowed down, service live of the pipeline is prolonged, and meanwhile impact noise can also be reduced.

Description

technical field [0001] The invention relates to a conveying device, in particular to a feeding pipeline. Background technique [0002] In the prior art, in mines, wharves and other workplaces, materials are often conveyed by means of closed conveying pipes. Elbow pipes are one of the conveying pipes. When in use, sometimes materials need to be unloaded from a high place. The material passes through a vertical section, then an inclined section, and then is discharged to a specific position. For granular materials, especially ore and coal, when they fall, they will impact the lower position of the vertical section and the inclined section. Pipe fittings cause wear. In order to solve the above problems, the existing technology adopts the method of locally thickening and increasing the wear-resistant layer, which has achieved certain effects and prolongs the service life of the elbow pipe fittings, but it still cannot fundamentally solve the wear-resistant problem of the elbow ...

[0002] In the prior art, in mines, wharves and other workplaces, materials are often conveyed by means of closed conveying pipes. Elbow pipes are one of the conveying pipes. When in use, sometimes materials need to be unloaded from a high place. The material passes through a vertical section, then an inclined section, and then is discharged to a specific position. For granular materials, especially ore and coal, when they fall, they will impact the lower position of the vertical section and the inclined section. pipe fittings causing wear

In order to solve the above problems, the method of locally thickening and increasing the wear-resistant layer in the prior art has achieved certain effects and prolongs the service life of the elbow pipe fittings, but it still cannot fundamentally solve the wear-resistant problem of the elbow pipe fittings.
