Abstract
The utility model relates to a cathode furnace chamber structure for an aluminium electrolysis trough. The utility model is characterized in that the included angle of an artificial extending leg (2) and a furnace chamber is 5 DEG-8 DEG, and the cathode square steel of a cleaning rod is two sections of square steels (3, 4) between which a buffer belt is arranged. The utility model can furthest protect the weak point of a cathode combining part, prolong the etched and corroded time of the weak point, increase the heat insulating time and form an alumina precipitating and stagnating zone, forming a furnace side as soon as possible and reducing the excessive precipitation of the furnace bottom, the two-section type square steel can prevent a cathode from being early damaged and extend the service life of the cathode, and the utility model has material saving.
Description
The utility model relates to metallurgical equipment, specifically the aluminium electrolytic cell cathode chamber structure.
The structure of aluminium electrolytic cell cathode burner hearth is the partly crucial of aluminium cell, and its quality directly influences the output of electrolysis of aluminum.The aluminum cell hearth structure of using has two defectives to life at present, the first manually stretch one's legs and the plain sole piece of negative electrode charcoal, the end joint portion between sticking with paste the weakest, it is the impaired breach of electric tank cathode, it two is that poker square steel temperature distortion amount in the plain sole piece of charcoal is big, has quickened the early damage of negative electrode burner hearth.
The purpose of this utility model provides a kind of deficiency that can overcome in the above-mentioned existing aluminium electrolytic cell cathode chamber structure, improves the aluminium electrolytic cell cathode chamber structure of the output of electrolysis of aluminum effectively.
The technical solution of the utility model is: the aluminium electrolytic cell cathode chamber structure, comprise the furnace wall, manually stretch one's legs, the negative electrode square steel and the anode of poker, mainly done following improvement: the angle that changes into the furnace wall of will manually stretching one's legs is 5 °～8 °, the negative electrode square steel of poker changes two sections square steel into, and a buffer strip is left in the centre.
Fig. 1 is the part sectioned view of aluminium electrolytic cell cathode chamber structure
Fig. 2 is the layout synoptic diagram of negative electrode square steel
Description of drawings: the 1-furnace wall, 2-manually stretches one's legs, 3-negative electrode square steel, 4-negative electrode square steel, 5-anode.
Cathode furnace chamber structure for aluminium electrolysis trough of the present utility model has following characteristics: 1) can protect to greatest extent the weak spot of thresold joint portion and prolong the time that this place is subjected to etch, corrosion; 2) increase temperature retention time; 3) can form a precipitation of alumina stagnant area, form as early as possible stove nation and reduce too much bearth precipitation; 4) the two-part square steel can prevent the early damage of negative electrode, prolongs its life-span; 5) economical with materials.
Embodiment of the present utility model is: as shown in Figure 1, comprise furnace wall 1, manually stretch one's legs, on the basis of the chamber structure of the negative electrode square steel of poker and anode 5, manually stretch one's legs 2 with the angle of furnace wall be 5 °～8 °, the negative electrode square steel of poker changes two sections square steel 3,4 into, a buffer strip is left in the centre, and being uneven in length of two sections negative electrode square steel 3,4, both sides are arranged alternately, as shown in Figure 2.
Claims (2)
1, a kind of aluminium electrolytic cell cathode chamber structure, comprise the furnace wall, manually stretch one's legs, the negative electrode square steel and the anode of poker, the angle of (2) and furnace wall of it is characterized in that manually stretching one's legs is 5 °～8 °, and the negative electrode square steel of poker is two sections square steel (3,4), and a buffer strip is left in the centre.
