Description
Technical field: flow into push-press type alumina feeding device and be a kind of novel aluminium cell in process of production, cause aluminum oxide powder to add reinforced executive device in the electrolyte melt to, be the major parts structure of aluminum oxide in aluminum electrolytic bath charging system, be mainly used in structure design, making and the installation of aluminum cell supplying system and the production of aluminium cell.
Technical background: what existing general aluminum oxide in aluminum electrolytic bath feeding device adopted usually is point type crust breaking blanking device at interval, point type is the crust breaker that mainly is configured to by the crust breaking cylinder, cylinder guidance connecting rod and the crust-breaking chips that are fixed on the aluminium cell upper beam framework of crust breaking blanking device at interval, and is made up of the aluminum oxide powder blanking device two big parts that charging box, constant-volume blanking device and blanking pipeline are configured to.
When electrolyzer carries out Aluminum Electrolysis Production, the alumina feeding device-be point type crust breaking blanking device at interval, at the operation program of carrying out the electrolyte solution interpolation aluminum oxide powder in aluminium cell, when implementing to feed in raw material function, open crust breaking cylinder earlier, move back and forth by drive cylinder guidance connecting rod of the piston in the crust breaking cylinder and crust-breaking chips, surging force by crust-breaking chips, condensation crust layer with ionogen above the electrolyte solution layer and aluminum oxide formation punctures earlier, form the hole type passage that an aluminum oxide powder can flow into the electrolyte solution layer, be commonly called as blanking hole, open the valve that is arranged on the constant-volume blanking device on the alumina feeding case again, make aluminum oxide powder through alumina blanking pipe and crust-breaking chips sidepiece, the space on electrolyte crust layer top, inertia by the movement of falling object, flow in the blanking hole, add in the electrolyte solution layer, finish a blanking program, aluminum oxide in the electrolyte solution layer is through the regular hour, when decomposition and consumption reduces to a certain amount of, by the next crust breaking blanking material program at interval of alumina feeding device execution, therefore existing general this alumina feeding device of aluminium cell is commonly called as again and is point type interval blanking device again.
The alumina feeding device of existing general aluminium cell is that point type interval crust breaking blanking device mainly exists following shortcoming and defect:
1, crust-breaking chips is in the incrustive layer excessively of frequent strike ionogen condensation, produce friction with electrolyte crust, with ionogen contact back in shock motion in the electrolyte solution layer with crust breaking and produce electrochemical etching, cause crust-breaking chips hammer body attrition serious, loss is very fast, must change in average 3-5 month.
2, when crust-breaking chips after attrition shortens and attenuates, crust-breaking chips forfeiture crust breaking punctures the function of crust layer blanking hole, the portion's rule that the blanking hole of crust layer can't be opened or opened, cause aluminum oxide powder can't all add in the electrolyte solution layer or addition inaccurate, thereby cause the inhomogeneous of the interior alumina concentration of electrolyte solution layer, influence the material balance of electrolyzer, cause the reduction of electrolytic cell currents efficient.
3, in aluminium cell, after crust-breaking chips is opened the blanking hole, aluminum oxide powder is in the electrolyte solution layer that is injected into through the tremie pipe port in the blanking hole time, will be through the negative pressure space of the opening in the electrolyzer, because aluminum oxide is pulverulent material, easily make and fly upward in the negative pressure space of alumina material in electrolyzer, aspirated out outside the electrolyzer by the smoke discharging dust removing system of donkey electrolyzer, can not participate in electrolytic reaction, cause the power dissipation of mass transport and smoke discharging dust removing system.
4, the production process of aluminium cell, it is a thermoelectrochemistry reaction process of carrying out continuously, the process of adding aluminum oxide in ionogen also should be an accurate successive process, existing general point type crust breaking is the interval cutting mode of feeding device formation at interval, self design itself does not just meet the aluminium cell work principle, adopt point type crust breaking feed way at interval, be to make that material balance in the ionogen is that the balance of alumina concentration maintains in the crest curve interval, the mechanism of keeping the ionogen chemical equilibrium is to destroy with a balance, the mechanism that the balance that lags behind is again repaired, the process of enforcement alumina feeding operation.This just because the feed way that the alumina feeding device is determined, and by the material balance chemical relationship that is lagged behind in the electrolyte solution layer that feed way determined, make the current efficiency of aluminium cell reduce, and cause the generation of the effect of grooves situation that has strengthened current loss and contaminate environment again.
Summary of the invention: satisfy the needs of aluminium cell thermoelectrochemistry reaction mechanism in order to make the aluminum oxide in aluminum electrolytic bath feeding device, cause alumina concentration in the electrolyte solution tend towards stability between a less linear section in the material chemical equilibrium, ensure the stable of aluminium cell electrolysis process situation, prevent the generation of the effect of grooves, improve current efficiency, reduce the power consumption of electrolytic aluminum, overcome above-mentioned existing general alumina feeding device with change, the crust-breaking chips that is point type crust breaking interval blanking device is easy to wearing and tearing, defectives such as aluminum oxide addition out of true, the invention provides a kind of novel aluminum oxide in aluminum electrolytic bath feeding device technical scheme, promptly flow into push-press type alumina feeding device.
