一种用于深海多金属结核开采的液锁分选中继仓

By installing a mineral processing device and a liquid lock structure in the relay chamber of the deep-sea mining system, the separation of ore and waste rock is achieved. The use of oil bladders to adjust buoyancy and a flow guiding device to reduce resonance solves the problems of energy waste, equipment wear and environmental pollution in deep-sea mining systems, and improves the system's adaptability and safety.

AI Technical Summary

Technical Problem

In deep-sea mining systems, the lifting of waste rock leads to energy waste, severe equipment wear, fatigue fracture of lifting pipelines, and pollution of the marine environment by a large amount of tailings slurry. The inability to adjust the buoyancy of relay bins results in poor system adaptability, and towing forces and vibrations exacerbate pipeline risks.

Method used

A mineral processing unit is set up in the relay warehouse to separate ore and waste rock. An insulating liquid is used to isolate the eddy current separator, a liquid lock structure is used to isolate seawater, an oil bladder is set to adjust buoyancy, a bladder-type pressure compensator is used to keep the internal and external pressures consistent, a flow guiding device is used to reduce resonance, and a circulating lifting pipeline is used to reduce tailings discharge.

Benefits of technology

It saves energy, reduces equipment wear, extends pipeline life, protects the marine environment, improves system adaptability, reduces the risk of breakage, enhances equipment corrosion resistance, and improves ore lifting efficiency.

Abstract

一种用于深海多金属结核开采的液锁分选中继仓，涉及深海采矿技术领域，包括仓体，仓体上连接有来料管和举升管路；仓体内设置有选矿装置，选矿装置能够对进入仓体的矿石中的精石和废石进行分离，分离后，精石通过举升管路输送至地面母船上，废石排放至海洋中。所述选矿装置包括分选机，矿石中的精石和废石通过分选机进行分选，实现分离。本发明创造性地在现有深海采矿系统的中继仓中设置了选矿装置，将选矿步骤前置到中继仓中，选出的废石直接排入海中，避免了废石的举升输送，从而大幅节约了能源，大幅延缓了泵的叶轮和举升管路内壁的冲刷磨损，消除了因矿石和废石比例随机波动导致载荷的频繁变化的问题。
