Abstract

The invention belongs to the technical field of deep-sea mining, in particular to a deep-sea mining lifting system integrating hydraulic power and air lifting. The invention includes a sea surface mining ship, a mineral storage container, a lifting riser, and a hydraulic lifting source; the lifting riser is laid upward from the mineral storage container to the sea surface mining ship, and the mixture is stored by the mineral under the drive of the hydraulic lifting source The container is transported to the sea surface mining ship; the air compression container is installed on the sea surface mining ship, and the upper pipeline access point and the air injection pipe are arranged on the lifting riser, one end of the air injection pipe is connected to the upper pipeline access point, and the other end is connected to the upper pipeline access point. Connect to outlet of compressed air container. The beneficial effect of the invention is that it does not need to greatly increase the power and quantity of hydraulic lifting sources, simplifies the structure, and saves input energy. Pipes such as lifting risers adopt flexible pipes, which are more suitable for seabed mining work under harsh sea conditions.

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...
