Solid-liquid separation conveying device and deep-sea mining device

Abstract

The invention discloses a solid-liquid separation conveying device and a deep-sea mining device, and relates to the technical field of solid-liquid separation instruments. The solid-liquid separation conveying device comprises a cyclone separation device, a feeding pipeline, an isolation assembly, a pressurizing device, a confluence assembly and a discharging pipeline, wherein the feeding pipeline communicates with a feeding port of the cyclone separation device; the isolation assembly comprises isolation tanks and first valves, the isolation tanks and the first valves are in one-to-one correspondence and communicate with each other, and the first valves communicate with a discharging port of the cyclone separation device; a liquid inlet of the pressurizing device communicates with a liquid outlet of the cyclone separation device; the confluence assembly comprises confluence devices, second valves and third valves, the isolation tanks and the confluence devices are in one-to-one correspondence and communicate with each other, the second valves communicate with a liquid outlet of the pressurizing device, and the third valves and the confluence devices are in one-to-one correspondence and communicate with each other; and the third valves communicate with the discharging pipeline. According to the solid-liquid separation conveying device and the deep-sea mining device, natural sedimentation is replaced by cyclone separation, so that the separation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separation equipment, in particular to a solid-liquid separation conveying device and a deep-sea mining device. Background technique [0002] The solid-liquid separation conveying device is often used in the process of sand transportation in mining. The solid-liquid separation conveying device can separate the solid-liquid mixture in the excavation and transport the separated solid material to a specific location. However, the existing fixed separation conveying devices generally use natural sedimentation to achieve solid-liquid separation, which leads to very low separation efficiency. [0003] Therefore, how to provide a solid-liquid separation conveying device with high separation efficiency has become an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In order to solve the above technical problems, the present invention provides a solid-liqui...
