Description
Technical Field
The utility model relates to the technical field of aluminum electrolytic cell crust breaking cylinder design and manufacture and aluminum electrolytic cell production, in particular to an aluminum electrolytic crust breaking cylinder height adjusting device.
Background
The conventional aluminum electrolysis crust breaking device consists of a crust breaking cylinder barrel, a piston rod, an upper end cover, a lower end cover, a middle swing shaft bracket and a pull rod. The crust breaking cylinder is connected with the lifting lugs through two sides of the middle swing shaft bracket and is fastened with a truss of an upper structure of the aluminum electrolytic cell through fixing bolts, and compressed air enables a cylinder piston rod to move up and down through an air valve fixedly connected with the cylinder during working and drives the crust breaking hammer head to move up and down in a reciprocating mode, so that the wear-resistant hammer head at the lower end of the crust breaking head impacts a fixed crust breaking blanking crusting point of the aluminum electrolytic cell.
At present, the aluminum electrolysis crust breaking cylinders are all fixed in height, the height of electrolyte crust of the aluminum electrolysis cell changes along with the height of two levels of electrolyte liquid and aluminum liquid in the electrolysis cell, and the working mode of the electrolysis cell cylinder has a plurality of disadvantages to the crust breaking operation mode of the electrolysis cell: (1) during the operation of electrolysis trough crust breaking head, the degree of depth that gets into the electrolyte is a fixed degree of depth, can cause crust breaking head during operation when two levels of electrolysis trough change, and the degree of depth that gets into the electrolyte is too dark or does not get into the phenomenon on electrolyte layer, and the degree of depth that crust breaking head got into the electrolyte is too dark to cause crust breaking head to puncture electrolyte layer and get into the aluminium liquid layer, influences the steady flow of aluminium liquid and accelerates the secondary oxidation reaction of aluminium liquid. The crust breaking head can not enter the electrolyte layer, so that the crust breaking head can not break through the surface of the alumina shell, and the alumina added into the electrolytic cell can not enter the electrolyte to influence the normal production of the electrolytic cell. And (2) workshop staff form crust breaking head-crust packet because of too deep depth of the crust breaking head entering the electrolyte of the electrolytic cell, and the staff need to continuously remove and process the crust breaking head-crust packet every shift according to 5-bath maintenance of each electrolyzer, so that the labor intensity of the workers is high, and the workload accounts for 30-40% of the whole work.
