Description
Technical field
The utility model belongs to the technical field of aluminum cell structure, is specifically related to a kind of aluminium cell splitter.
Background technology
The preheating and baking of aluminium cell is the important step in the electrolysis production process.Preheating and baking should create conditions for startup, also should be the optimization of subsequent production, technico-economical comparison and the prolongation of cell life simultaneously and lays a solid foundation.The roasting method of current Chinese large-sized prebaked cell mainly adopts the baking coke particles method, when adopting the baking coke particles method,, have a lot of holes because the contact of burnt granulosa is not tight, and electrolyzer is in cold state, burnt granulosa total electrical resistance is bigger, when electrolyzer is switched on, if give total current at short notice, can cause bath voltage too high, cell lining is produced very big thermal shocking, cause the electrolyzer early damage easily, be unfavorable for the prolongation of cell life.In order to reduce the thermal shocking of total current to electrolyzer, therefore in roasting process, splitter will be used so that make electrolyzer under the electric current that is lower than potline current intensity, carry out roasting, thereby reduce the thermograde in the heat-processed, reduced the danger that inner lining material damages.Along with temperature in the groove constantly rises, the conduction situation of burnt grain and anode, negative electrode is improved gradually, can progressively remove splitter.
Present most producer utilizes the steel splitter to shunt, and concrete grammar is that the weldable steel band is shunted between the steel pawl of anode rod and cathode steel bar.Vigorously asking Coarse-hempen-fabric two spot weld modes such as taking, is directly to be connected between the steel pawl of anode rod and the cathode steel bar with the iron splitter of the round steel of a bending or steel plate manufacturing, and the steel pawl tie point mode of connection of iron splitter and anode rod is the welding of iron steel; The mode of connection of iron splitter and cathode steel bar tie point also is the welding of iron steel.Though the steel pawl of iron splitter, cathode steel bar, anode rod on-load (not having electric current to pass through) not when this two spot weld itself, but the big bus that less than is two meters far away but has load (being generally more than the 40KA), therefore welding is subjected to the high-intensity magnetic field influence, can not guarantee the welded seam quality.The shunting action of iron splitter is to determine according to the cross-sectional area of iron splitter, the weakest place is exactly the weld seam that splitter contacts with male or female, therefore can shunt uneven phenomenon, when shunting is uneven, cause bias current easily, at this moment the iron splitter of part can cause weak link fusing because of the electric current bias current, and loses shunting action, makes electric current more inhomogeneous, cause vicious cycle, even cause Serious Accidents such as stopping groove.And the space is less between electrolyzer, and utilization this method operation more complicated not too is applicable to big area electrolyzer electrical roasting.
In calcination work, require to take all splitters apart in 24 hours according to electrolysis process, because an electrolyzer has tens of splitters (determining according to anode group number), these splitters can be taken apart stage by stage according to shunting situation different time, may take a slice or several apart at every turn, the operating space is little, workload is big and be in the operating condition of high temperature (the splitter temperature reaches 600 degrees centigrade) and high-intensity magnetic field, brings very burden to operation.And take the splitter of vigorously asking Coarse-hempen-fabric two spot weld modes because all weld, and so dismounting must employ gas welding or weld seam is given a tongue-lashing out in electric welding, splitter is no longer shunted, operation is quite difficult and dangerous under above-mentioned severe environment.
And, use existing aluminium cell dividing technology, be easy to take place electrolyzer and thrust the little bus accident of negative electrode because of the sidepiece seepage.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of aluminium cell splitter, simplified production operation, improved shunting effect, because of the generation that the sidepiece seepage thrusts the little bus accident of negative electrode, avoid full electrolytic series is impacted guaranteeing also can to prevent under the impregnable situation of streaming rate electrolyzer.
