Measuring method and tool for electrolyte level or aluminum level in aluminum electrolysis cell

Abstract

The invention discloses a measuring method and tool for the electrolyte level or aluminum level in an aluminum electrolysis cell. When the electrolyte level or aluminum level in the aluminum electrolysis cell is measured, a measuring nager is manufactured into an L-type measuring nager formed by a vertical iron rod and a horizontal iron rod, the horizontal iron rod of the L-type measuring nager is placed on a horizontal supporting base, the vertical iron rod of the L-type measuring nager is vertically inserted into electrolyte or molten aluminum in the aluminum electrolysis cell, at the moment, a mark of the electrolyte or molten aluminum will be formed on the vertical iron rod of the L-type measuring nager, then the L-type measuring nager is taken down from the horizontal supporting base and placed on a measuring trolley, the vertical iron rod of the L-type measuring nager is attached to a vertical supporting rod, which is perpendicular to a horizontal support and provided with a graduated scale, of the measuring trolley, in this way, the value corresponding to the mark on the vertical iron rod can be directly read from the graduated scale of the vertical supporting rod, and the value is a measurement value. The measuring method and tool have the advantages of being high in measurement precision and efficiency, small in measuring workload, simple in structure, convenient to operate and use and the like.

Description

technical field [0001] The invention relates to a method and a tool for measuring the electrolyte level or aluminum level of an aluminum electrolytic cell, and belongs to the technical field of measuring the electrolyte level or aluminum level of an aluminum electrolytic cell. Background technique [0002] The two levels of the electrolytic cell refer to the electrolyte level and the aluminum level. The two levels are important indicators for evaluating the cell condition of the electrolytic cell. The stability of the two levels is the basis for the stability of the electrolytic cell. Therefore, two-level measurement is one of the basic processes of aluminum electrolytic production, and the accuracy of its measurement results is crucial to the process control of electrolytic cells. [0003] At present, the method of measuring the two levels mainly uses the measuring rod to be directly inserted into the electrolyte or aluminum liquid of the aluminum electrolytic cell, so that...

Problems solved by technology

With this existing measurement method, since the bottom of the aluminum electrolytic cell is not very flat and there are some sundries, when the measuring braid touches the sundries at the bottom of the aluminum electrolytic bath for measurement, the measurement result is very inaccurate In addition, when using the measuring rod in the prior art to measure, the vertical part of the measuring rod is easy to tilt, which will also cause a large error

And when adopting existing technology to measure, often need 2 operators

Therefore, the existing methods of measuring the electrolyte level or aluminum level of aluminum electrolytic cells not only have the problem of low measurement accuracy, but also have the problems of low measurement efficiency and heavy labor
