Abstract

The invention discloses a hydraulic conveying testing system for deep sea mining. The hydraulic conveying testing system for the deep sea mining comprises a water surface supporting platform, an intermediate bin, an uplink conveying pipe, a downlink conveying pipe, a feed bin, an intermediate bin, a feeding machine, an ore collecting machine and the like, wherein the uplink conveying pipe is connected between the intermediate bin and the water surface supporting platform; the feed bin is arranged in the intermediate bin and connected with the uplink conveying pipe through the feeding machine; the ore collecting machine is connected with the feed bin through a conveying pipeline; the uplink conveying pipe is connected with a lifting pump in series; the uplink conveying pipe is provided with an emergency blow-down valve above the lifting pump, and the emergency blow-down valve is used for plugging the uplink conveying pipe and discharging materials out of the uplink conveying pipe; the downlink conveying pipe is communicated with the uplink conveying pipe through the intermediate bin. The hydraulic conveying testing system for the deep sea mining is capable of meeting the conveying requirements of coarse-granule ores and avoiding blockage, and is good in safety.

Description

technical field [0001] The invention relates to the technical field of deep-sea mining operations, in particular to a deep-sea mining hydraulic conveyance test system suitable for collecting deep-sea granular minerals. Background technique [0002] In recent decades, pipeline hydraulic transportation technology has been widely used in the field of solid slurry transportation, such as deep sea mining, hydraulic coal transportation and river dredging, due to its advantages of low operating cost and relatively high reliability. [0003] In the process of slurry pipeline transportation, due to the influence of the concentration, velocity and particle size of the transported materials on the transportation performance of the transportation pipeline, it will lead to problems such as low transportation efficiency or serious impact on transportation safety due to pipeline blockage, which will greatly increase the operation. cost. In deep-sea mining projects, due to the complexity o...
