Description
Technical field
The utility model relates to a kind of aluminum cell anode effect predictor, belongs to the aluminium cell technical field.
Background technology
Anode effect is a kind of universal phenomenon in the fused salt electrolysis, especially with the most noticeable in the electrolysis of aluminum.In Aluminium Electrolysis, when anode effect took place, bath voltage was elevated to tens of volts suddenly, and bright arc discharge phenomenon appears in the anode periphery, and potline current fluctuates.Ordinary production is disturbed in the generation of anode effect, consumes a large amount of electric energy, has a strong impact on every electrolysis economic and technical norms.In today that energy-saving and environmental protection become more and more important, particularly should the strict generation of controlling anode effect in large-scale pre-baked cell is produced in the Aluminium Electrolysis.
In the aluminium electrolysis process, the constant DC source imports electrolyzer by anode large bus bar and some groups of carbon anodes parallel with one another and implements electrolytic action, and under the normal electrolytic condition, every group of carbon anode shared the magnitude of current and should be equated.If aborning, the effecting reaction area of one group of (several groups) anode bottom reduce or anode and electrolyte melt interface between resistance increase, then anodic current distributes and also will change.The anode that the effecting reaction area reduces or interface resistance increases is shared the magnitude of current and is reduced, all the other one group of (several groups) anodes are shared the magnitude of current to be increased, quicken the carrying out of electrolytic reaction, generating gas can not in time get rid of, also can reduce anode effecting reaction area, hinder the current delivery between anode and melt greatly, anodic current distributes and changes from kainogenesis.Circulation successively, last all anodic effecting reaction areas all reduce, and anodic current density raises.When reaching critical anodic current density, polarizing voltage sharply raises, and anode effect takes place.If when anodic current distributes change, when certain group (several groups) anodic current density reaches critical current density, also local anode effect or scintillation effect can take place.
Summary of the invention
The technical problems to be solved in the utility model is, a kind of aluminum cell anode effect predictor is provided, and takes place to disturb ordinary production to overcome the anode effect that prior art exists, and deficiency such as can not in time forecast.
In order to solve described technical problem, the utility model is taked following technical scheme: bolt 2 is arranged on anode rod 1, and bolt 2 is connected with opening vitrified pipe 3, and opening vitrified pipe 3 is connected with threading vitrified pipe 6, and threading vitrified pipe 6 is connected with voltage monitoring instrument 7.
Bolt 2 is a Steel Bolt.
The distance of two steel bolts is 300mm on the anode aluminium guide bar.
The utility model is set equidistant steel bolt on the anode aluminium guide bar, bolt by be built in the opening vitrified pipe slidably, high temperature resistant wire is connected with Voltage detector, can detect the equidistant fluctuation of pressure drop of anode in real time, monitoring anodic current distribution situation.

Fig. 1 is anode rod of the present utility model and bolt connection diagram;
Fig. 2 is opening vitrified pipe of the present utility model and high temperature resistant wire connection diagram;
Fig. 3 is a whole connection diagram of the present utility model.
Embodiment
Embodiment of the present utility model: equidistant 300mm inlays built-in two steel bolt 2(as schematically shown in Figure 1 on each anode rod 1), bolt is by being built in slip tube 4 in the opening vitrified pipe 3 and high temperature resistant wire 5(as schematically shown in Figure 2) connect threading vitrified pipe 6, Voltage detector 7 connects (as schematically shown in Figure 3), threading vitrified pipe 6 is fixed on the aluminium cell superstructure, and opening vitrified pipe 3 internal fixing are on the threading vitrified pipe.This device can be monitored the equidistant fluctuation of pressure drop of anode in real time, judges the anodic current distribution situation, analyzes the anode clogged conditions, suitably handles, and can avoid the generation of anode effect.
