Undersea polymetallic sulfide mining device based on high-pressure water jet

Abstract

The invention discloses an undersea polymetallic sulfide mining device based on high-pressure water jet. The device comprises cutting nozzles, a lifting pipe, lifting nozzles, a high-pressure water pump and a high-pressure cabin, wherein a mineral collecting cover is arranged at the bottom of the lifting pipe, a cutting nozzle support is arranged at the lower part of the mineral collecting cover,the cutting nozzles are arranged on the cutting nozzle support, outlets of the cutting nozzles directly face a undersea polymetallic sulfide mineral, a lifting nozzle support is arranged in the middleof the lifting pipe, the lifting nozzles are arranged on the lifting nozzle support, and outlets of the lifting nozzles extend into the lifting pipe and face upwards; the high-pressure water pump isconnected with the high-pressure cabin, and the high-pressure cabin is connected with the cutting nozzles and the lifting nozzles. The device integrates a cutting function and a mineral collecting function; during work, the cutting process and the mineral collecting process can be performed simultaneously and are in seamless connection; the probability that polymetallic sulfide particles diffuse toward sea water due to desynchrony of the cutting process and the mineral collecting process is reduced, pollution of the mining process to the undersea environment is reduced to the greatest extent.

Description

technical field [0001] The invention relates to the field of seabed mining equipment, in particular to a seabed polymetallic sulfide mining device based on high-pressure water jets. Background technique [0002] Seabed polymetallic sulphides are a new seabed mineral resource discovered and recognized after seabed polymetallic nodules and cobalt-rich crusts, which are rich in copper, zinc, gold, silver and other metals. Seabed polymetallic sulphides have shallow water depths and are relatively close to land, with high economic value and good commercial exploitation value. According to relevant international conventions, the commercial mining of seabed polymetallic sulphides needs to control the disturbance to the seabed environment during the cutting process and ore collection process within a certain range, and minimize the impact of the mining process on the seabed environment. There are two links in the mining process that are likely to have an impact on the seabed enviro...
