Description

TECHNICAL FIELD

[0001] The utility model belongs to the liquid layer separation technical field of multi-liquid layer static tank, especially relates to the multi-layer material layered extraction device of extraction liquid static tank in hydrometallurgy process. BACKGROUND

[0002] Hydrometallurgy process adopts the mode of organic extraction to extract metal elements, and the liquid after extraction is introduced into a static tank for static separation and layering. The liquid after layering usually includes a lower aqueous solution layer (target product), an upper organic layer, and a middle three-phase material layer. When the liquid layer thickness of the three-phase material layer and the organic layer located above is too large, the probability of mixing of the two liquid layers at the liquid layer interface increases, especially the density and physical properties of the three-phase material layer are between those of the aqueous solution layer and the organic layer, which has certain compatibility with both, and is not conducive to improving the separation effect. Therefore, the different liquid layers need to be separated in time. In the actual production process, most production enterprises adopt the mode of manual timed extraction to separate the liquid layers. This mode has the following problems: 1. The position of the liquid layer has great uncertainty, especially the middle layer. It is difficult to accurately position the target liquid layer by manual extraction, and it is not easy to operate; 2. Manual extraction can usually only be carried out at one point, and the extraction speed is slow. Moreover, the static tank is usually large, and the planar area of the liquid layer is also large. The extraction speed of the liquid layer at the extraction point is fast, and the extraction speed of the liquid layer far from the extraction point is slow. Therefore, a liquid flow is inevitably formed due to the difference in liquid surface, which disturbs the interface of the adjacent liquid layers and causes secondary mixing. It is also inevitable to extract a considerable amount of liquid of the adjacent liquid layers, which leads to insufficient purity of the extracted liquid and requires a long time for secondary static separation, thereby increasing the processing efficiency and processing cost. In addition, the liquid of the lower layer and the upper layer is separated by setting an overflow plate and an oil baffle. However, this separation mode has the following problems: during the extraction process, there are always three layers of liquid in the static tank, and the position of the middle layer changes greatly. It is still difficult to discharge through the fixed position outlet, and this separation mode cannot guarantee the purity of the separated material, especially when the liquid layer interface is close to the end of the overflow plate and the oil baffle. The probability of the outflow of different liquid layers from the same outlet is greater. CONTENT OF THE UTILITY MODEL
