Description

Technical Field

[0001] The utility model relates to the technical field of washing liquid treatment, in particular to a settling tank washing liquid treatment system. Background Art

[0002] The alumina settling tank downwash liquid treatment system is a solid-liquid separation system specifically used in the alumina production process. In the production of alumina, especially in the separation and washing process of sintering red mud, a large amount of suspension containing solid particles will be produced. These suspensions need to be separated by solid-liquid separation to extract alumina and recover the washing liquid for recycling. The downwash liquid will be guided to the downwash liquid treatment unit through the outlet collection system of the settling tank. In the treatment unit, filtration, clarification or other physical and chemical methods are usually used to further remove solid particles and suspended matter in the downwash liquid. These treatment methods can effectively improve the quality of the downwash liquid and reduce the impurity content therein. Secondly, the downwash liquid that has been preliminarily treated may also need to be chemically treated to adjust its pH value, remove specific impurities or adjust its composition. This may include adding appropriate chemical reagents, such as acids, alkalis or flocculants, to promote the precipitation or separation of impurities.

[0003] The flocculant is poured into the sedimentation tank, and a stirring structure is usually used to stir the flocculant and the washing liquid so as to perform solid-liquid separation and thus treat the washing liquid. However, conventional stirring results in low mixing efficiency and reduces work efficiency. Therefore, a sedimentation tank washing liquid treatment system is proposed. Utility Model Content
