[0002] Sedimentation separation is a common industrial separation technology, and gravity sedimentation method is based on the difference in specific gravity of sediment and supernatant. After the mixture is placed for a period of time, the heavier sediment will sink to the bottom of the container, and the supernatant will float above the sediment. The supernatant can be taken out by tilting the container or using a suction device to obtain solid precipitate. When the solution mixed with the sediment is poured, it will cause loss of solid target. If it is not poured, the collected solid target will contain a lot of water, increasing the energy cost of solid drying. In the same tank, whether it is poured or sucked, it will increase the disturbance of the sediment and the supernatant, making the solution more turbid, causing the mixed layer to expand and the water content of the solid to increase, further increasing the solid loss or the energy cost during drying.
