In order to alleviate the urgent need for various mineral resources in industrial society and the gradual exhaustion of mineral resources on land, it is particularly necessary to improve the mining technology level of mineral resources in the deep sea, and ore mixed transportation and lifting technology is the key to deep-sea mining technology.

[0003] After searching, the publication number CN110671333A discloses a multi-stage pump for lifting coarse particles in deep-sea mining. The type of pump belongs to the diagonal flow pump, which is characterized by high head and wide flow channel, and solves the problem of coarse particles blocking the pump of the lifting electric pump, which is the core component of the existing pipeline lifting system. The present invention includes an outer shell, a multi-stage pump and a submersible motor. The external environment of the outer shell is seawater, and the submersible motor and the multi-stage pump are protected internally. The submersible motor is at the bottom of the multi-stage pump and is connected to the multi-stage pump through a rotating shaft. Six-stage diagonal flow pumps are connected in series to form a multi-stage pump, and each stage of the diagonal flow pump includes an impeller body and a space guide vane body. An annular flow channel is provided between the inner wall of the outer cylinder and the submersible motor. The flow channel is connected to the inlet transition section at the bottom and the pump inlet section at the top, and forms a complete flow channel with the flow channel inside the pump and the outlet transition section, so as to ensure that the mixture of solid particles and seawater can be smoothly lifted or refluxed in the flow channel.
