Description

TECHNICAL FIELD

[0001] The present application relates to the field of deep-sea mining, in particular to a deep-sea mining system bin device with water inlet at the bottom. BACKGROUND

[0002] The ocean is a huge resource treasure house of mankind, and the international seabed area contains rich mineral resources. With the increasing demand for resources and the depletion of land resources, mining mineral resources in the deep sea has become a direction for the world to solve energy problems in the future. At present, the mineral resources with commercial mining value in the deep sea include polymetallic nodules, cobalt-rich crusts and polymetallic sulfides.

[0003] The mineral resources in the seabed are mostly in the deep sea of 3000-6000 meters, and a mining system that is simple to maintain and can realize long-term operation is needed. The mining systems developed internationally at present include a drag bucket mining system, a continuous chain bucket mining system, a shuttle boat mining system, etc. However, the reliability and stability of the above mining systems cannot be guaranteed, and there are also problems such as low efficiency and poor economy. In recent decades, the pipe lifting mining system has been widely used in the field of ore slurry transportation due to its low operating cost and relatively high reliability, and has become the most studied deep-sea mining system at home and abroad. During transportation, the concentration of ore particles, the transportation speed, the particle size of ore particles, and the shape of ore particles have a very obvious influence on the transportation performance of the transportation pipe, which easily leads to low transportation efficiency. In order to finally realize the successful application of pipe transportation in the field of deep-sea mining, it is necessary to analyze the transportation characteristics of the slurry in the pipe during transportation.

[0004] Therefore, it is necessary to establish a land-based slurry lifting platform for simulating deep-sea mining. Through the platform, the influence of different particle concentrations, particle sizes, particle shapes, and transportation speeds on the fluid form in the transportation pipe can be analyzed, and the vibration and stress of the pipe can also be analyzed to study the influence of these parameters on the lifting efficiency of the system, so as to obtain better transportation parameters and deep-sea mining system design data, and effectively solve the problems of the existing system that cannot guarantee its reliability, stability, and efficiency. SUMMARY

In this process, mineral particles are added into the feeding pipe 5, the first valve 7 is opened to make the mineral particles enter the storage space 8, the first valve 7 is closed again, the second valve 6 is opened to make the mineral particles fall into the bin chamber, and then the second valve 6 is closed. The water in the bin chamber is continuously driven by the power device to enter the storage chamber (the bottom of the storage chamber is provided with a filter screen, the mineral particles are intercepted, and the water enters the circulation downward), and then re-enters into the bin chamber through the water inlet pipe-transition pipe. And flows into the riser again, so that the water completes the circulation in the lifting platform. The circulating water flow will disturb the mineral particles in the bin chamber and generate upward lifting force, and the mineral particles will move upward along the riser and remain in the storage chamber 14. The above can complete the lifting of the mineral particles. When the mineral particles in the bin chamber cannot be lifted, the transition pipe and the filter screen 12 can be removed, and the residual mineral particles can be manually taken out.
