Embodiment Construction
[0021] An embodiment of the aluminum suction tube aluminum suction operation method of the present invention, the method adopts the aluminum suction tube to suck out the aluminum liquid from the electrolytic cell, and the liquid inlet of the aluminum suction tube is provided with an anti-clogging for sealing the aluminum suction tube liquid inlet, And the anti-blocking aluminum suction tube can melt or burn after being inserted into the aluminum liquid, and disappear at the liquid inlet. During the aluminum suction operation, during the process of inserting the anti-clogging aluminum suction tube into the aluminum liquid, the liquid inlet of the aluminum suction tube is blocked due to the anti-clogging, and the liquid electrolyte is prevented when the aluminum suction tube enters the electrolyte in the upper layer of the aluminum liquid. Enter the aluminum suction tube, therefore, the electrolyte will not stick to the aluminum suction tube or enter the vacuum package wall; when...

The invention discloses a method for sucking out aluminum liquid during aluminum electrolysis, and an aluminum sucking pipe and an anti-blockage plug for implementing the same. The method uses the aluminum sucking pipe to suck out aluminum liquid from an electrolytic tank. The liquid inlet of the aluminum sucking pipe is equipped with the anti-blockage plug in sealed match with the aluminum sucking pipe. After the aluminum sucking pipe is inserted into aluminum liquid, the anti-blockage plug can melt or burn after being heated, and disappears at the liquid inlet. During aluminum sucking, whenthe aluminum sucking pipe equipped with the anti-blockage plug is inserted into aluminum liquid, as the anti-blockage plug blocks up the liquid inlet of the aluminum sucking pipe, the anti-blockage plug plugs the liquid inlet of the aluminum sucking pipe to prevent electrolyte from entering when the aluminum sucking pipe passes through the electrolyte on upper layer of the aluminum liquid; and the anti-blockage plug is melted through heating so as to open the aluminum sucking pipe when the aluminum sucking pipe enters the aluminum liquid, thus facilitating aluminum liquid sucking. The invention can avoid blockage of the aluminum sucking pipe and decrease of vacuum bag capacity, so as to carry out pipe cleaning and bag cleaning.
Description
technical field [0001] The invention relates to a method for sucking aluminum liquid out of an electrolytic tank by an aluminum suction pipe in the production of electrolytic aluminum, in particular to an aluminum suction pipe and an anti-blocking method for implementing the method. Background technique [0002] In the production process of electrolytic aluminum, the aluminum suction tube is needed to suck out the aluminum liquid from the electrolytic cell. When the aluminum suction tube is inserted into the electrolytic cell for aluminum suction operation, it first needs to pass through the electrolyte layer covered above the electrolytic cell aluminum liquid. This layer of electrolyte is about 12 cm thick. When the aluminum suction tube passes through the electrolyte layer, the liquid electrolyte invades the aluminum suction tube and enters the aluminum suction tube and the vacuum bag with the aluminum liquid. After solidification, it is bonded and fixed on the inner wall o...
