Technical field
The present invention relates to mining technique field, more particularly, to a kind of marine mining engineering machine that raw ore sand is gathered at deep-sea
Tool.
Background technology
With the increasingly reduction of landing field mineral resources, people start to turn to sight into the sea for containing abundant mineral resources
Ocean, in some areas, it has been found that substantial amounts of Seashore Placer Deposits, importantly titanium-containing magnet ore deposit, at present, common mining mode
It is that the ore in sand form in seabed with sand pump is drawn into by mining platform or mining by a marine mining platform either mining dredger
On ship, then the raw ore sand collected is transported on the cargo ship of transhipment with corresponding Pulp pump again, cargo ship is by raw ore sand
The ore dressing plant for being transported to land carries out ore dressing to be formed available for the washed ore smelted.For example, a kind of in Chinese patent text
Disclosed " deep-sea collecting and distributing type mining system " is presented, notification number is CN1065191C, the system includes collecting machine, delivery pipe, water
Upper ship or pier, the upper end of delivery pipe are connected with waterborne vessel or pier, and lower end is stretched into water provided with middle roll-over

Put, be suspended in seabed surface by each predetermined route Ji Kuang.
However, there are the following problems for existing ocean mining method：Carried out due to digging up mine with ore dressing in different places, because
And not only waste substantial amounts of transport power containing a large amount of useless CHARACTERISTICS OF TAILINGS SANDs in the raw ore sand that cargo ship is transported, cause cost
Increase, and remaining CHARACTERISTICS OF TAILINGS SAND also needs transhipment again to handle after ore dressing, thus cost is further increased, and at CHARACTERISTICS OF TAILINGS SAND
Reason is improper will also to cause more serious environmental problem.
In addition, usually requiring to use magnetic separator in existing ore dressing program, its general principle is as follows：Raw ore sand is transported to
The inside of one rotation has the drum overhead field regions of high-intensity magnetic field, has magnetic raw ore sand and is attracted to roller table
Face, and nonmagnetic ore in sand form will not then be adsorbed by roller and directly thrown away by roller, with the rotation of roller, raw ore sand reaches rolling
Cylinder non-magnetic place and be pulled out away from, so as to realize the screening and separation of raw ore sand.For example, one kind is open in Chinese patent literature

But there is the problem of ore dressing is not accurate enough with magnetic separator ore dressing, because the grade of raw ore sand Central Plains ore in sand form is in ladder
Degree distribution, therefore, the magnetic field intensity in roller needs to set a reasonable value, to adsorb such as grade 3 percent
More than ten ore in sand form.Due to the percussion of raw ore sand, therefore, the ore in sand form that cylinder surface grade is slightly above 30 percent is fallen on
Very likely directly thrown away because of percussion by roller, so as to cause the waste of resource.If the magnetic field improved in roller is strong
Degree, then can make to be mixed with the CHARACTERISTICS OF TAILINGS SAND that a part of grade is less than 30 percent in the washed ore selected.

Liquid level sensor is set respectively in storehouse.
Unlike the prior art, the present invention is directly provided for the magnetic separator 3 of ore dressing, the magnetic separation equipment on hull
There are a CHARACTERISTICS OF TAILINGS SAND delivery outlet 31 and a washed ore delivery outlet 32, and connect between washed ore delivery outlet and concentrate store
It is connected to washed ore conveying device.
So, when the raw ore sand in seabed is extracted into first crude ore bin by sand pump, the first slurry pump startup, so that will
Raw ore sand in first crude ore bin is extracted into second crude ore bin, that is to say, that first crude ore bin herein plays one
The effect of turnover.Raw ore sand in second crude ore bin passes through corresponding Pulp pump（Not shown in figure）Send into magnetic separator, raw ore
Sand is by isolating the washed ore that can be used for smelting and discarded CHARACTERISTICS OF TAILINGS SAND, washed ore of the washed ore from magnetic separator after magnetic separator
Exported in delivery outlet, be then transported in concentrate store and stored by washed ore conveying device.And the CHARACTERISTICS OF TAILINGS SAND separated then from
Exported in the CHARACTERISTICS OF TAILINGS SAND delivery outlet of magnetic separator, and tailings storehouse is delivered to by the CHARACTERISTICS OF TAILINGS SAND collection conduit 5 being connected with tailings storehouse.Tail
The bottom in sand storehouse is connected by pipeline with the suction sand mouthful of a tailings pump 4, and therefore, tailings pump can be in real time by the mine tailing in tailings storehouse
Sand, which extracts and backfills pipeline 6 by mine tailing, is delivered to the seabed away from mining area, so that the backfill on the spot of CHARACTERISTICS OF TAILINGS SAND is realized, so as to
The intractability of CHARACTERISTICS OF TAILINGS SAND is greatly simplified, and reduces corresponding mining cost.In order to avoid springing up for seawater backfills mine tailing
