Abstract

The invention discloses an exploitation system for deep-sea poly-metallic nodules. The exploitation system includes a mine collecting sub system and a mine raising sub system, and a control system controlling operation of the mine collecting sub system. The mine collecting sub system includes a submarine mining robot, an umbilical cable and a mine collecting groove. The mine raising sub system includes a submersible sewage pump, a mine raising soft tube, an exploitation platform and at least one separator arranged on the exploitation platform. Two ends of the mine raising soft tube are respectively connected to the mine collecting sub system and the submersible sewage pump. The submersible sewage pump is connected to a liquid phase outlet of the separator through a pipeline and is arranged at the water depth of 160-300 m. Through the principle of connected vessels, height differential pressure is generated through water suction and discharge by the submersible sewage pump, wherein the submarine poly-metallic nodules collected and sorted by the submarine mining robot are directly conveyed to the floating-caisson exploitation platform through the mine raising soft tube without impellers in the pump and are sorted and filtered through the separators, thereby achieving continuous work of mine collecting, mine sorting, mine raising and mine storage.

Description

Preferably: described production platform is floating box type production platform.
Preferably: described mining system also includes extracting boat and for the polymetallic nodules by the solid-phase outlet of separator It is delivered to the conveyer belt on described extracting boat.
Another object of the present invention, a kind of utilizes what deep sea polymetallic nodule exploited by mining system as above to open Excavating technology, it comprises the following steps
1) undersea mining robot by umbilical cables and is raised ore deposit flexible pipe transfers to the 3000-6000 rice of seabed, controlling system Under the effect of system, seafloor robot carries out polymetallic nodules collection in seabed, and is mixed by the muddy water of the polymetallic nodules collected Compound is sent into after mechanical agitation and jet desliming and is raised in the flexible pipe of ore deposit;
2) polymetallic nodules raised in the flexible pipe of ore deposit carrying out solid-liquid separation, isolated low solid phase sea water is through being positioned at the depth of water Return after submersible sewage pump circulation at 160-300 rice and drain into sea, and store isolated solid-phase multi metal tuberculosis
The beneficial effects of the present invention is, the mining system of the present invention, to sea-floor relief without particular/special requirement, can substantially realize Full landform operation.Polymetallic nodules can realize exploitation continuously under conditions of without pump, can increase substantially the life-span of pump, Reducing impeller to the abrasion of tuberculosis and destruction, meanwhile, the particle diameter of tuberculosis is not limited by submersible sewage pump caliber.
Accompanying drawing explanation
Fig. 1 shows the structural representation of mining system of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.
As it is shown in figure 1, the mining system of deep sea polymetallic nodule of the present invention includes: collection ore deposit subsystem, Yang Kuangzi System and control system.Wherein, described collection ore deposit subsystem includes undersea mining robot 1, umbilical cables and mining collecting trough, institute Stating umbilical cables can be that the offer of described undersea mining robot 1 is transferred, power transports, instruction controls transmission, video signal transmission Deng, the ore body gathered then can be connected mud band water by blanket type strand suction effect and send into collection in the lump by described undersea mining robot 1 Ore deposit groove.In the present invention, described undersea mining robot 1 can use four wheel crawler independent suspensions, and each Athey wheel can Thering is provided and drive, have good obstacle detouring, more ditch performance so that mining operations is not limited by sea-floor relief, basic realization exists Freely walking of the full landform in seabed.Further, described mining collecting trough is provided with mechanical stirring device and jet desliming device, Ore body mud mixture in mining collecting trough is sent into after mechanical agitation and jet desliming process and is raised ore deposit subsystem.
Described ore deposit subsystem of raising includes submersible sewage pump 2, raises ore deposit flexible pipe 3, production platform 4 and be positioned on production platform 4 extremely A few separator 6, wherein, described in raise the bottom of ore deposit flexible pipe 3 and be connected with undersea mining robot 1, for the many metals in seabed Return the passage providing stable in tuberculosis, and there is certain flexibility and stroke, can be with undersea mining robot 1 in sea Bottom row is walked, described in raise ore deposit flexible pipe 3 and use short connection type steel wire rope load-bearing, use Flange joint between flexible pipe;Described separator 6 It is connected with the described other end raising ore deposit flexible pipe 3, for the polymetallic nodules that will raise in ore deposit flexible pipe 3 in the solidliquid mixture of conveying Separating with sea water, in the present invention, described separator 6 includes vortex sieve and filter screen 61, wherein, described filter screen The filtering accuracy of 61 is less than 1mm.Bottom stayed by described vortex sieve after being sieved by ore body bigger for particle diameter, pass through subsequently Filter screen 61 ore body less for particle diameter is crossed filter cake to bottom separator 6 so that ore body and sea water are separated.Separator 6 isolated low solid phase sea water are inhaled in submersible sewage pump 2 by pipeline and are circulated.How golden the isolated solid phase of separator 6 is Genus tuberculosis then can be transported to extracting boat 7 by conveyer belt 5 and store.In the present invention, described production platform 4 uses floating Box design, has location linkage and compensation of undulation function, and by least one separator 6 being arranged on production platform, Can realize but in separator 6, polymetallic nodules are collected full or time separator 6 breaks down, it is possible to cut in the case of not termination of pumping Shift to another set of separator 6, and then realize the seriality of exploitation.Especially, in the present invention, described submersible sewage pump 2 is pacified It is put at depth of water 160-300 rice, utilizes law of connected vessels, produce certain height pressure difference by the water-pumping/draining of submersible sewage pump 2, The gravitional force of sea water overcomes management lose along stroke pressure and raise outer density pressure differential in ore deposit flexible pipe 3, by undersea mining robot The 1 seabed polymetallic nodules gathering sorting, are delivered directly to floating box type without the impeller of pump exploit by raising ore deposit flexible pipe 3 Platform 4, decreases the polymetallic nodules destruction to impeller.
Additionally, the control system in described mining system, it can control undersea mining robot 1 according to predetermined path row Walk and carry out Ji Kuang, extracting boat 7 then have provide for underwater installation deposit, lay/reclaim, operation supporting and maintenance, Store the functions such as Ore.
