Abstract
The invention relates to the field of aluminium electrolytic cells, and provides an online monitoring device of an aluminium cell cathode current. The online monitoring device is characterized in that two ends of a DC (direct current) sensor are respectively connected with a signal inverter and an LCD (liquid crystal display). Because of adopting the technical scheme, the distribution status of the electrolytic cell cathode current can be mastered in time, a timely and exact basis can be provided to operating personnel so as to adjust the cathode current in time, so that the electrolytic cell cathode current can be evenly distributed according to technological conditions, the breakage bottom of an electrolytic cell caused by flawing due to the uneven distribution of the cathode current can be prevented effectively, and electric energy is saved drastically, so that anciently a great deal of manpower and material resource consumption caused by adopting another mode to test electric currents are avoided.
Description
Technical field
The present invention relates to aluminium cell field, is a kind of aluminium electrolytic bath cathode current on-Line Monitor Device.Be widely used on the electrolyzer of Aluminum Electrolysis Production process.
Background technology
Aluminium industry in national economy in occupation of consequence.The production of modern aluminum industry, mainly adopts electrolytic process to obtain aluminium, in electrolyzer, passes into powerful galvanic current, at negative electrode and anode, carries out electrolysis.In aluminium production process, guarantee that stablizing of aluminium cell is one of key factor promoting optimization production always.The impact of the factors such as the interior temperature of electrolyzer groove, cracks bottom land in the roasting stage because distribution of current is uneven especially and causes bottom land damaged, and even early damage, not only reduces primary aluminum quality, and impact is produced, and brings huge financial loss.When bearth damage, cathode steel bar are corroded, cathode current distribution will change.If can anticathode distribution of current carry out routine measurement, just may find in time its ANOMALOUS VARIATIONS, thereby likely take corresponding measure, prevent the generation that electrolyzer morbid state changes.Traditional cathodic current test is to measure after cathode soft bus voltage drop value is revised conversion just can obtain actual current value.Correction factor is determined by electric tank cathode structure design characteristics, its cathode construction design difference of different grooveds, and correction factor is also different.Correction factor is relevant with cathode soft bus resistance, with the length of cathode soft bus and group number number relevant.For obtaining cathode current distribution correction factor, generally, first from cathode soft bus resistance value, choose one as standard or reference, other cathode soft bus resistance value is compared the data that draw with fixed reference value be exactly cathode current distribution correction factor, the complicated dangerous precision that do not have of this survey method, to be not suitable with the development of modern industry.
Summary of the invention
The object of the invention is to provide a kind of aluminium electrolytic bath cathode current on-Line Monitor Device.By Hall detection mode and liquid-crystal display, combine, to electrolytic aluminium electrolytic tank each negative electrode flexible lead electric current real time on-line monitoring and demonstration.
Technical scheme of the present invention is: a kind of aluminium electrolytic bath cathode current on-Line Monitor Device, it is characterized in that DC current sensor one end is connected with signal converter, and the signal converter the other end is connected with liquid-crystal display.
Owing to having taked technique scheme, can grasp in time electric tank cathode distribution of current situation, for adjusting cathodic current in time, operator provide foundation promptly and accurately, guarantee that electric tank cathode electric current is according to the distribution of technology condition stable equilibrium, effectively prevent that because cathode current distribution is uneven, bottom land being cracked causes bottom land damaged, significantly save electric energy, avoided a large amount of man power and materials that in the past caused by alternate manner test current to consume.
Accompanying drawing explanation
Fig. 1 is System Working Principle figure of the present invention.
In the drawings: 1, DC current sensor; 2, signal converter; 3, liquid-crystal display.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further illustrated.
In Fig. 1, DC current sensor 1 one end is connected with signal converter 2, and signal converter 2 the other ends are connected with liquid-crystal display 3.
The real current that DC current sensor 1 is flexible coupling aluminium electrolytic cell cathode detects, by signal converter 2 by signal convert to numerary signal by RS485 communication transfer to liquid-crystal display 3, liquid-crystal display 3 demonstrates the distribution of current work simulation state graph of real-time current and the whole electrolyzer of each cathode collector bar.
