technical background

With the continuous exploitation of terrestrial mineral resources, the terrestrial mineral resources are increasingly depleted, and the demand for minerals by human beings is increasing day by day, and the contradiction between the depletion of minerals and the increase in demand has become increasingly prominent. As we all know, the ocean area accounts for two-thirds of the earth's area, and obtaining new incremental mineral resources from the seabed is one of the feasible ways at present.

The ore lifting device is an important part of the deep sea mining system, and its function is to lift the ore on the seabed to the support ship on the sea surface. At present, it is difficult to raise minerals from the deep seabed to the surface. Various methods have been tried in foreign deep-sea mining, and domestic deep-sea mining has also carried out some research in recent years, from the initial sled mining, continuous chain bucket mining, automatic shuttle mining, to deep-sea centrifugal mining in recent years. Machine-pumped mining, etc., but the technology is not mature enough. The most promising method of existing deep-sea mining is the hydraulic pipeline lifting method, that is, after the ore and seawater are mixed in a certain proportion, they are lifted from the seabed to the supporting ship on the sea surface through the pipeline, but the slag accumulation caused by the poor structure reduces the reduction. effect. And because the seawater after separation will still have some extremely fine particles, if it is directly discharged into the sea, it will damage the ecological environment. Although the deep-sea centrifuge pumping method improves the mining efficiency to a certain extent, it cannot be achieved in one step, requiring multi-stage transportation, and due to the wear of the pulp, the blades are easily damaged, the service life is short, and the reliability and economy are not high. Due to the small displacement and large stroke of some diaphragm pumps, the diaphragm is easily damaged by fatigue and the efficiency is not high. Therefore, deep-sea mining urgently needs a lifting device and system with high efficiency, long life, small displacement fluctuation, and environmental protection to improve the efficiency of deep-sea seabed minerals and ensure the economic feasibility of mining.
