Pipeline mud conveying device

Abstract

The invention discloses a pipeline mud conveying device. The pipeline mud conveying device comprises an outer pipeline, an inner pipeline concentric with the outer pipeline, and an air inlet formed in the outer pipeline, and a high-pressure air way is formed by a gap between the outer pipeline and the inner pipeline. A plurality of high-frequency vibrators are arranged in the high-pressure air way and located on the air inlet side. A high-pressure air hole communicating with the high-pressure air way is formed in the inner pipeline and located in the air inlet side. Each high-frequency vibrator comprises a pair of vibration supports, a vibrator shaft, a plurality of blades and a vibration steel ball arranged on the top of each blade through a vibration spring. The defects that during channel dredging work, the flowing resistance of mud in the pipelines is large, hydraulic power along the way is reduced rapidly, consequently, a dredger mud conveying system pipeline is abraded and blocked, the conveying distance is short and energy consumption is high are overcome, and therefore the flowing resistance of the mud in the pipelines is reduced, and hydraulic losses of mud along the way are reduced.

Description

technical field [0001] The invention belongs to the technical field of pipeline mud transportation, in particular to a pipeline mud transportation device. Background technique [0002] On the dredger for channel dredging, the dredging mud pump sucks up the cut mud, and transports the mud from the dredging point to the distant mud storage and processing point through the large-diameter and long-distance mud pipeline. Due to the characteristics of many components, high concentration and large flow rate of the dredged mud, the mud is in a multiphase flow state when it is transported in the pipeline, and its flow rate is disturbed greatly and the flow field is complex. This leads to the large flow resistance of the mud in the pipeline, and the rapid drop of hydraulic pressure along the route, which often leads to the wear, blockage, short conveying distance and high energy consumption of the pipeline of the dredger's mud conveying system. The limited dredging operation scope, d...

AI Technical Summary

Problems solved by technology

As a result, the flow resistance of mud in the pipeline is large, and the hydraulic pressure drop along the way is fast, which often leads to pipeline wear, blockage, short transportation distance and high energy consumption of the dredger's mud transportation system, which affects and limits dredging ships. The scope of dredging operations, dredging production efficiency and the distance of silt discharge have become a bottleneck problem restricting dredging operations

During the channel dredging operation, the flow resistance of the mud in the pipeline is large, and the hydraulic drop along the way is fast, which often has the disadvantages of wear and blockage of the mud delivery pipeline of the dredger, short delivery distance and high energy consumption
