Land slurry lifting experimental platform for deep-sea mining

Abstract

The invention relates to the technical field of deep-sea mining equipment, and particularly discloses a land slurry lifting experimental platform for deep-sea mining. The land slurry lifting experimental platform comprising a bin, and a material falling machine is arranged at the bottom of the bin. A descending conveying pipe and a lower connecting pipe are connected through a three-way valve I, the bin communicates with the descending conveying pipe through the three-way valve I in a bypass manner, and after being converged through a three-way valve II, the lower connecting pipe and an outletof the material falling machine are connected with a water bag. A water tank is connected with a water inlet of the bin and a water inlet of the water bag through a water feed pipe. The water bag isdivided into two paths after passing through a three-way valve III, the two paths communicate with an outlet of a vertical centrifugal pump and an inlet of a horizontal centrifugal pump, and the outlet of the vertical centrifugal pump and the inlet of the horizontal centrifugal pump communicate with an ascending conveying pipe after being converged through a three-way valve IV. A pressure stabilization water tank located at the high position is connected with the water bag through a pressure stabilization water pipe. By means of the experimental platform, a slurry lifting experiment of the circulating work condition / backpressure work condition can be carried out on the vertical centrifugal pump / horizontal centrifugal pump.

Description

technical field [0001] The invention relates to the technical field of deep sea mining equipment, in particular to an onshore slurry lifting experiment platform for deep sea polymetallic nodule mining. Background technique [0002] The ocean is a huge treasure house of resources owned by human beings, and the international seabed area contains rich mineral resources. With the continuous increase of human demand for resources and the depletion of land resources, the mining of mineral resources hidden in the deep seabed has become a direction for the future world to solve energy problems. At present, mineral resources with commercial mining value in the deep sea include polymetallic nodules, cobalt-rich crusts, hydrothermal sulfide ores, etc. [0003] Polymetallic particles mostly exist in the deep sea surface of 3000-6000 meters, and require a mining system that is easy to maintain and can operate for a long time. At present, the mining systems that have been developed in t...
