High-drop falling-type pipeline energy dissipation conveying system

Abstract

The invention provides a high-drop falling-type pipeline energy dissipation conveying system. The conveying system comprises a plurality of falling pipelines and a plurality of energy dissipation pipelines; every adjacent falling pipelines are communicated through one energy dissipation pipeline; the upstream end of each energy dissipation pipeline is connected to the bottom of one falling pipeline positioned at the high position; the downstream end of each energy dissipation pipeline is connected to the top of one falling pipeline positioned at the low position; flow guide mechanisms are arranged at the bottoms of the falling pipelines and at the connecting positions of the falling pipelines and the energy dissipation pipelines; L-shaped connection channels are formed between the falling pipelines and the energy dissipation pipelines through the flow guide mechanisms. According to the invention, through the innovate design of the L-shaped connecting structures between the falling pipelines and the energy dissipation pipelines, ore pulp slurry from the falling pipelines can flow to the energy dissipation pipelines smoothly and freely, and phenomenon of eddy current abrasion to the pipelines, caused by buffering and overflow of the slurry is completed removed, so that energy dissipation of the high-drop slurry is realized to the utmost extent, the operation service life of the slurry pipeline system is prolonged, and the conveying efficiency of the slurry pipelines is improved.

Description

technical field [0001] The invention relates to a slurry pipeline conveying system, and more specifically relates to a high-drop drop-type pipeline energy-dissipating conveying system. Background technique [0002] With the rapid economic growth of our country, especially the sustained and stable development of metallurgy, petrochemical, petroleum, chemical fertilizer and other industries in recent years, with the increase of energy prices, the transportation cost has become higher and higher, and the use of hydraulic pipelines to transport solid materials, and other Compared with transportation (such as railways and highways), it has short transportation distance, low infrastructure investment, adapts to terrain and can use height difference potential energy, does not occupy or occupy less land, does not pollute the environment and is not disturbed by external conditions, and can realize continuous operation , reliable technology, transportation costs are only 1 / 6 to 1 / 10 o...

AI Technical Summary

Problems solved by technology

When the iron concentrate slurry is transported from the top of the mountain to the foot of the mountain, it will generate huge kinetic energy. If this huge kinetic energy is not dissipated, it will cause huge damage to the receiving device and seriously affect the service life of the equipment.
