The invention discloses a deep sea ore hydraulic conveying system model experiment device which comprises a water storage pool, a relay bin, a separation bin, an aggregate bin, a storage bin, an ore pulp pump, a lifting hard pipe, an information collection system, an ore transmission system and the like. A relay bin provided with a jet device is supported in the water storage pool, a lifting hardpipe is directly inserted into the lower end of the relay bin, an ore pulp pump is installed on the lifting hard pipe, and when the ore pulp pump works, ore particles settled at the bottom end of therelay bin are sucked into the lifting hard pipe and conveyed to the storage bin through a pipeline; ore pulp fluid in the storage bin is conveyed into the separation bin through the return pipe underthe action of dead weight of the storage bin, after ore pulp passes through the separation bin, liquid water flows into the water storage pool under the action of dead weight of the separation bin, and ore particles fall into the aggregate bin, fall into the relay bin after passing through the ore conveying system and enter the next working cycle. And when the system works stably, the informationacquisition system starts to work, and the flow field of the key part in the system is monitored in real time, so that stable transmission characteristic parameters of the ore particles and the flow field distribution condition in the relay bin are obtained. The experimental device is simple in structure and convenient to use, and the experimental result can provide basic data for design and analysis of the hydraulic conveying system of the ore raising pipeline.
Description
technical field [0001] The invention relates to deep-sea mining, in particular to an experimental device for studying the movement characteristics of ore particles in an ore pipe in deep-sea mining. Study the flow field distribution characteristics of the key parts of the conveying system, and provide basic data for the design and analysis of the hydraulic conveying system of the mine lifting pipeline. Background technique [0002] With the continuous development of the world economy, the demand for mineral resources is also increasing. Excessive resource development has caused the earth's land mineral resources to become increasingly exhausted. In order to meet the needs of human survival and development, countries around the world have set their sights on mineral resources since the last century. The vast ocean. The function of the deep-sea ore conveying system is to lift the ore collected from the seabed to the mining ship on the sea surface, which is one of the core tec...
