Detailed description of the invention
The embodiments described below are further described with reference to the accompanying drawings.
In the experimental apparatus for simulating the influence of seawater fluctuation in deep-sea mining on the pipeline shown in fig. 1, an experimental centrifugal pump 3 and a first motor 2 are fixed through a first support 4, and the first motor is connected with a rotating shaft of the experimental centrifugal pump through a coupling 2. An inlet pressure sensor 5 and an outlet pressure sensor 6 are respectively arranged at the inlet and outlet pipelines of the experimental centrifugal pump. The exciter 32 is connected to a spring 31 acting on the fifth duct 29 through a mechanical sensor 33. An electromagnetic flowmeter 30 is also mounted on the fifth pipe 29 to measure the flow rate of the mixed liquid. The solid-liquid separator 20 is driven by a second motor 17, and the agitator 27 is driven by a third motor 28, both of which are fixed by the second bracket 8. The water tank is fixed by a third bracket 13. The frame comprises a first support, a second support and a third support.
After the experiment has started, the on-off valve 18 on the first conduit is opened and the water in the water tank 15 enters the water tank 19 and then the second conduit 26. By adjusting the three-way valve 24, the particles are fed from the third conduit 25 into the second conduit to be mixed with the water. The mixed solution is then fed into the mixer 27 to be sufficiently mixed. At this time, the switch valve 10 is closed, the switch valve 9 is opened, and the mixed liquid flows into the fourth pipeline 7; the mixed liquor will then enter the laboratory centrifugal pump 3, through the laboratory centrifugal pump 3 into the fifth pipe 29. The inlet pressure sensor 5 and the outlet pressure sensor 6 record the pressure change of the inlet and outlet pipelines of the experimental centrifugal pump 3. The frequency of the vibration exciter 32 can be adjusted, and the mechanical sensor 33 acts on the pipeline to enable the pipeline to generate slight vibration; therefore, the fluctuation frequency of the seawater is simulated, and the impact of the seawater on the pipeline under different working conditions is further simulated. The electromagnetic flow meter 30 will record the flow in the fifth pipe 29. The mixed liquor then enters the solid-liquid separator 20, water enters the water tank through the screen 21 under the action of gravity, and particles enter the particle tank 23 under the action of the extrusion screw 22 in the solid-liquid separator. This was cycled through the experiment.
After the experiment is finished, the particles can be discharged through the bottom of the third pipeline 25 by adjusting the three-way valve 24. After entering the second pipe 26 through the water tank 19, the water enters the mixer 27, carries out the particles remaining in the mixer and cleans the mixer. The on-off valve 9 is closed and the on-off valve 10 is opened, and water and residual particles enter the sixth pipeline 11 and finally enter the waste water collection tank 12 to be discharged. Finally, the on-off valve 14 is opened, and the water in the water tank can flow out through the pipeline at the bottom of the water pipe and be recovered.
