Description
The utility model relates to a kind of device of exploiting deep sea polymetallic nodule, specifically is waterpower combined type Ji Kuang device.
The top layer of each ocean bottom sediment is composed and is being deposited the abundant polymetallic nodules of reserves in the world, and it contains multiple metal, has very high the economic exploitation and is worth.Since the seventies in 20th century, the Ji Kuang device of experimental study mainly contains mechanical type, waterpower formula and combined type three major types.The structure of mechanical type Ji Kuang device is than waterpower formula complexity, and it is fragile to dig tooth, and the deposit that takes is too many, and the collection mine mouth easily by bulk tuberculosis ore and bottom sediment obstruction, reach for a long time, the reliable continuously running difficulty of high efficiency is very big; The negative pressure suction tuberculosis ore that waterpower formula Ji Kuang device utilizes jet to produce, its shortcoming is to gather a large amount of bottom sediments, the variation of the collection mine mouth end off sea height is very big to the influence of collection ore deposit efficient; The compound Ji Kuang device that existing double nozzle collection, inclination carrier bar are carried overcome the shortcoming of above-mentioned two kinds of Ji Kuang devices, but the rotating motion part of carrier bar or scraping plate transmission mechanism is many, complex structure, and operating reliability is low.
It is minimum that the purpose of this utility model is carried ooze with regard to providing a kind of tuberculosis ore is gathered up from the seabed, simple in structure to sea-bottom deposit damage layer minimum, the high efficiency Ji Kuang device that reliable operation and fault rate are low.
The technical solution of the utility model is: comprise and gather and carry two parts, wherein be provided with the nozzle that two rows link to each other with the latent pump of Ji Kuang, the oblique relatively seabed of jet of two row's nozzles, above nozzle, be provided with the kuppe at oblique rear, the outlet of kuppe is connected with the material sucking port of carrying ejector, its discharging opening is received Hoisting System with flexible pipe, and the oblique discharging opening of ejector nozzle is connected with carrying submersible pump with feed pipe.
In technique scheme, seabed tuberculosis ore moves upward towards bottom sediment off sea under the ascending current effect of double nozzle jet impact force and formation, owing to install translation forward, carry the material sucking port of ejector through the kuppe guiding, the high-speed water jet of ejector nozzle produces negative pressure in suction tube, the mixture of tuberculosis ore and water is sucked in the suction tube from the kuppe outlet, and be sent to Hoisting System in the ore storage bin through flexible pipe under the pressure effect of increasing in the effluxvelocity conversion.
Use mining apparatus of the present utility model, not only have sea-bottom deposit damage layer minimum, carry deposit hardly, device does not contact with the seabed and the resistance of motion is little, can not gather advantages such as relatively large rock, most important character is, owing to substituted scraping plate transmission mechanism with the conveying ejector, there is not rotating motion part, and with the collection conveying mechanism of Ji Kuang device with unite two into one for the induction system of ore storage bin to Hoisting System by collecting machine for the ore deposit, collection ore deposit apparatus structure is greatly simplified, thereby reached high reliability long-time continuous high efficiency Ji Kuang.
Describe in detail below in conjunction with the embodiment accompanying drawing.
At first accompanying drawing is described.
Fig. 1 represents structure chart of the present utility model, is a kind of embodiment;
Fig. 2 represents second kind of embodiment of the present utility model;
Fig. 3 represents to carry three kinds of different structures of ejector nozzle, and wherein 3a is a bilateral nozzle formula; 3b is a ring-type nozzle formula; 3e is a center nozzle formula.
Fig. 4 represents that Ji Kuang device of the present utility model and Hoisting System integration of operation carry out the embodiment of deep sea polymetallic nodule ore mining.
In the embodiment shown in fig. 1, by collection ore deposit submersible pump (not drawing among the figure), double nozzle (12), (13), kuppe (15) and surge bunker (16) are formed the waterpower acquisition system, by the collection ore deposit direction of motion (3), forwardly locate to be provided with two rows nozzle (12) separated by a distance near seabed (1), (13), the back lower place of back row's nozzle (13) fixedly is hung with rubber baffle (14) the two row's nozzles (12) that are extended down to seabed (1), (13) link to each other with collection ore deposit submersible pump outfall with pipeline, in nozzle (12), (13) top is provided with sweptback kuppe (15), a surge bunker (16) is received in its outlet, and surge bunker (16) top is provided with mesh (17).The jet induction system is by carrying submersible pump (not drawing among the figure), ejector (18) and delivery hose (23) are formed, the material sucking port (19) of ejector (18) links to each other with surge bunker (16), its discharging opening (22) is received Hoisting System supplying on the ore storage bin (8) near seabed (1) with flexible pipe (23), the oblique discharging opening of ejector nozzle (21) (22) links to each other with carrying submersible pump with feed pipe (20).
The design principle and the course of work are: start collection ore deposit submersible pump, its big flow low-pressure water is by two row nozzle (12,13) oblique relatively seabeds (1) ejections, make tuberculosis ore (2) rinse out deposit towards the end off sea (1), under the ascending current effect that forms, be picked up, because Ji Kuang device (3) translation forward, be directed to surge bunker (16) through kuppe (15), the mesh (17) through the top in surge bunker (16) is got rid of the deposit that carries.The effect of rubber plate washer (14) is that row's nozzle (13) is located to flow out behind the current direction after stopping, guarantees that double nozzle (12,13) can form ascending current.The water under high pressure that the conveying submersible pump is discharged (20) is by the road sent into nozzle (21), produce high-speed jet, make and produce negative pressure in the suction tube (19), the interior tuberculosis ore of surge bunker (16) (2) is sucked, and in discharge nozzle (22), mix with water jets, water jets passes to its a part of kinetic energy and is inhaled tuberculosis ore (2) in the mixed process, along with rate conversion discharge nozzle (22) internal pressure raises, under this pressure effect through flexible pipe (23) with tuberculosis ore (2), be transported to the Hoisting System seabed in ore storage bin (8).
Fig. 2 represents another kind of embodiment of the present utility model, i.e. the outlet of kuppe (15) directly links to each other with the suction tube (19) of ejector (18), has cancelled the surge bunker (16) among Fig. 1 embodiment.But utilize Hoisting System (9) further to get rid of the deposit that carries near the mesh for ore storage bin (8) in seabed, make collection ore deposit apparatus structure simpler.
