Embodiment 1

[0033] Such as Figure 2~4 As shown, a buoyant self-elevating polymetallic nodule transmission system, the transmission system includes: a mining vehicle, a buoyant self-elevating transmission system, and a mining ship system; wherein the mining vehicle is used to collect polymetallic nodules for processing and then transfer to the buoyant self-elevating The buoyant jack-up transmission system further processes the polymetallic nodules and then transmits them to the mining ship system through buoyancy.

[0034] Preferably, the buoyant self-elevating transmission system described in this embodiment includes: a water control hatch, a nodule mass sensor, a paraffin mass sensor, a pulsator stirring device, a hydraulic rod, and an auxiliary stirring device. The mining ship system includes a mining ship, Transmission pipeline recovery device, transmission pipeline, constant temperature transmission pipeline, nodule paraffin separation device; among them, the upper part of the buoyan...

Embodiment 2

[0042] Such as figure 1 As shown, a kind of buoyancy self-elevating polymetallic nodule transmission method, utilizes the polymetallic nodule transmission system described in embodiment 1 to carry out transmission, specifically comprises the following steps:

[0043] (1) Pipeline laying: the transmission pipeline 4 and the constant temperature transmission pipeline 5 are respectively laid from the mining ship 1 to the seabed. Water hatch door 601; add liquid paraffin to the constant temperature transmission pipeline from the inside of the mining ship until the valve 603 with the paraffin quality sensor.

[0044] (2) The mining vehicle collects polymetallic nodules: the mining vehicle collects the polymetallic nodules on the seabed through the jet device in the collection head 7, and transports them to the crusher with the model number PEW400×600 through the conveyor belt; the polymetallic nodules pass through the crusher After crushing, the diameter of the particles is below ...

Abstract

The invention belongs to the field of mining of deep-sea mineral resources, and specifically discloses a buoyant self-elevating transmission system and method for polymetallic nodules. The transmission system includes: a mining vehicle, a buoyant jack-up transmission system, and a mining ship system; the mining vehicle is used to collect polymetallic nodules and then transfer them to the buoyant jack-up transmission system. After treatment, it is buoyantly transferred to the mining vessel system. The method mainly includes: (1) laying pipelines, (2) collecting polymetallic nodules by mining vehicles, (3) wrapping polymetallic nodules with paraffin, (4) transporting a mixture of paraffin-polymetallic nodules, (5) separating and recycling polymetallic nodules paraffin. The lifting system of the present invention does not need power, and after quantitative liquid paraffin and polymetallic nodules are fully mixed, the condition that its own buoyancy is greater than gravity can be achieved, thereby greatly reducing energy consumption.

Description

technical field [0001] The invention relates to the field of mining of deep sea mineral resources. In particular, it relates to a buoyant self-elevating transmission system and method for polymetallic nodules. Background technique [0002] The deep seabed is the largest untapped mineral resource on earth. So far, the deep-sea mineral resources that have been found to have economic value mainly include: polymetallic nodules containing nickel, copper, cobalt and manganese, crusts rich in cobalt, nickel, copper and manganese, and crusts rich in copper, lead, zinc and gold. and silver in seafloor polymetallic sulphide deposits. Although the mineral resources are so rich, the mining and transportation of minerals are facing huge challenges due to the fact that their occurrence environment is the deep sea. In deep-sea mineral resources, polymetallic nodules are distributed in a single layer on the surface of deep seabed sediments in the form of bulk materials, and their shapes ...
