The liquid aluminum and the liquid electrolyte coexist in the electrolytic tank, and because the densities of the two substances are different, an upper layer and a lower layer are formed, and the aluminum liquid is inThe lower layer, the electrolyte liquid on the upper layer. The important technical index for judging whether the aluminum electrolytic cell operates well is the height (level) of electrolyte liquid and aluminum liquid, which is called two-level measurement for short, and the process of measuring the level of the electrolyte liquid and the level of the aluminum liquid is called two-level measurement.
At present, domestic manufacturers generally adopt a manual measuring method, namely an L-shaped measuring drill rod, such as a steel drill rod with the diameter of 16mm, and a steel plate ruler with the measuring range of 400mm is matched. When measuring, one end of the measuring drill rod is inserted into the liquid of the aluminum electrolytic cell and is placed for about 5-10 seconds, the electrolyte liquid and the aluminum liquid are adhered to the drill rod, and the two solutions have obvious boundary lines. The height of the two solutions can be measured by holding the drill rod with one hand and the steel plate ruler with the other hand for measurement. However, this kind of measurement method is inefficient on the one hand, and on the other hand has potential safety hazard because the high temperature drill rod (generally about 800 ℃) is not easy to operate by one hand under the influence of strong magnetic field in the aluminum electrolysis plant, and is easy to scald face or hand. Therefore, only by optimizing the measuring tool and simplifying the operation process, the measuring efficiency can be improved, and the potential safety hazard of scalding is eliminated.
Therefore, in the two-level measurement process, how to improve the measurement work efficiency, avoid the potential safety hazard that the face and the hands of the operator are scalded, and let the operator who measures the two levels work in a safe environment, and the work efficiency is obviously improved, is a difficult problem that needs to be solved urgently in the aluminum electrolysis workshop.
