Problems solved by technology

[0010] The air lifting system introduces high-pressure compressed air to the bottom of the marine riser for mineral transportation through an air pipeline. Taking advantage of the low specific gravity of the air, an upflow is formed in the lifting riser, thereby driving the minerals to rise. At prese

Embodiment Construction

[0033] Below in conjunction with accompanying drawing and embodiment the present invention is described further as follows:

[0034] Such as figure 1 A deep-sea mining vertical lifting system showing a combination of hydraulic lifting and air lifting includes a sea surface mining vessel 3, a mineral storage container 10, a lifting riser 7, and a hydraulic lifting source; the lifting riser 7 consists of a mineral storage container 10 is laid upwards to the surface mining vessel 3, and the mixture is transported from the mineral storage container 10 to the surface mining vessel 3 under the drive of the hydraulic lifting source; An upper pipeline access point 6 and an air injection pipe 5 are provided. One end of the air injection pipe 5 is connected to the upper pipeline access point 6 and the other end is connected to the outlet of the air compression container 4 .

[0035]As the power source, the hydraulic lifting source generates a certain pressure output during work, and fo...

Abstract

The invention relates to the technical field of deep-sea mining, in particular to a hydraulic power and air lift integrated deep-sea mining lifting system. The hydraulic power and air lift integrated deep-sea mining lifting system comprises a sea surface mining ship, a mineral storage container, a lifting vertical pipe and a hydraulic lifting source. The lifting vertical pipe is upwards laid onto the sea surface mining ship through the mineral storage container, a mixture is conveyed from the mineral storage container to the sea surface mining ship through driving of the hydraulic lifting source, and an air compression container is installed on the sea surface mining ship; and an upper pipeline access point and an air injecting pipe body are arranged on the lifting vertical pipe, one end of the air injecting pipe body is connected to the upper pipeline access point, and the other end of the air injecting pipe body is connected to an outlet of the air compression container. The hydraulic power and air lift integrated deep-sea mining lifting system has the beneficial effects that the power and quantity of the hydraulic lifting source does not need to be greatly increased, the structure is simplified, and input energy is reduced. Pipelines such as the lifting vertical pipe adopt flexible pipelines, and the hydraulic power and air lift integrated deep-sea mining lifting system can be more suitable for seabed mining operation under a severe sea condition environment.

Description

technical field [0001] The invention belongs to the technical field of deep sea mining, in particular to a vertical lifting system for seabed mining applied in deep sea. Background technique [0002] Most of the earth is covered with water. In different depths of the ocean, there are a large number of seabed minerals. Their reserves and content are unmatched by continents. Because minerals are different from oil, this is mainly reflected in the minerals from the seabed. The methods of transportation to land vary widely. On the one hand, the transportation methods are completely different, and the transportation is difficult; on the other hand, production efficiency and economy are also important considerations. Requiring programs presented great challenges. [0003] In general, a complete seabed mining system includes the following components: [0004] Submarine mining vehicles, including deep-sea mineral cutting machines, grinding machines, collecting machines, etc., are...
