Abstract

The utility model relates to an anode steel claw for aluminum electrolysis. The anode steel claw comprises an anode guide rod, a crossbeam connected to the bottom of the anode guide rod and steel claw legs mounted on the crossbeam, wherein each steel claw leg comprises an internal steel claw leg, a steel cylinder and a boss; the outside of the internal steel claw leg is sheathed with the steel cylinder and the boss is arranged on the top of the outer circumference of the internal steel claw leg and is used for supporting the steel cylinder; the steel cylinder is of a tapered structure having gradually increased diameter from top to bottom; the boss is welded on the upper part of the steel cylinder, and the lower part of the steel cylinder and the inner steel claw legs have a common bottom to transmit electric current. According to the utility model, since the anode steel claw for aluminum electrolysis is provided with the steel cylinder and the boss, the steel cylinder needed to be cut and replaced after the steel cylinder is worn, which both ensures the welding quality and effectively reduces the labor intensity. Furthermore, a hollow cavity is arranged between the steel cylinder and the inner steel claw legs so that the steel consumption of steel claw legs is reduced on the premise that the energized cross-sectional area of the steel claw legs is ensured, thereby ensuring the energizing effect and saving resources.

Description

A kind of anode steel claw for aluminum electrolysis
Technical field
The utility model relates to technical field of aluminum electrolysis, relates to specifically a kind of anode steel claw for aluminum electrolysis.
Background technology
Anode steel jaw is that aluminium point is separated in the anode system of groove and played the electric action of forming a connecting link, the material of anode steel jaw is Normal Steel Casting at present, the working temperature of the anode steel jaw leg bottom of Normal Steel Casting material is 400 ~ 900 ℃, very easy oxidative exfoliation, in use this position easily attenuates, the aluminium manufacturer's anode steel jaw shank oxidation rate having is now too fast, mainly to be trapped among around anode steel jaw shank due to aluminum oxide powder and ionogen, the iron generation electrochemical reaction of aluminum oxide and steel pawl shank in process of production, a life cycle 28-33 days surface can be oxidized 10mm-15mm, leg diameters reduces by 20 mm-30 mm, within 1 year, use several times, below leg diameters reaches 100mm time, just can not use.
Steel pawl is mainly used in passing through of anodic current, as steel pawl shank attenuates, the resistance that makes steel pawl shank is increased, and affects steel pawl energising efficiency, thereby affects the power consumption efficiency of electrolytic tank electrolysis aluminium.Each aluminium manufacturer will not change thousand groups of 2---3 not etc. every year, and not etc., expense is inconsiderable for 500-800 kilogram of each steel pawl.Waste is large.
At present conventional method of redress is that the part steel pawl leg root attenuating is prescinded, then does a steel pawl leg and be welded on original position and go, and between the larger 110-180mm of welded section, welds one.Time is long, and expense is high.The docking of the larger cross section of thickness, the not weld penetration of steel pawl, can only weld first and second, welding is many, and steel pawl is just done for, this mode remedy the cost that has not only reduced the production capacity of electrolysis of aluminum but also greatly increased electrolysis of aluminum.
Utility model content
The utility model is in order to solve above-mentioned technical problem, a kind of electrolytic aluminum anode steel pawl is provided, and its anti-oxidant, anti-corrosion, high temperature resistant and long service life, even after outside steel cylinder scraps, only need the excision to steel cylinder to change, reduced workman's labour intensity.
The technical scheme that the utility model adopts is: a kind of anode steel claw for aluminum electrolysis, the crossbeam that comprises anode rod, be connected with anode rod bottom and be arranged on the steel pawl leg on crossbeam, described steel pawl leg comprises internal steel pawl leg, is set in the steel cylinder of internal steel pawl leg outside and is arranged on internal steel pawl leg excircle top and for supporting the boss of steel cylinder, described steel cylinder is the pyramidal structure that diameter increases gradually from top to bottom, and the welding of the top of steel cylinder and boss, bottom and internal steel pawl leg have a common bottom surface with transmission current.
Between described internal steel pawl leg and steel cylinder, it is cavity structure.
The ferrophosphorus that is provided with cast between described crossbeam and anode rod is connected.
On the outside surface of described steel cylinder, be provided with decorative pattern.
Described steel cylinder is coated with one deck Al outward 2o 3protective coating.
Described crossbeam is rectangle or trapezoidal.
Between described crossbeam and anode rod, be welded with conduction reinforced company fishplate bar.
The beneficial effects of the utility model: the utility model is provided with steel cylinder and boss, after steel cylinder wearing and tearing, only need cutting to replace, not only guarantee welding quality but also effectively reduced workman's labour intensity, in the utility model, between steel cylinder and internal steel pawl leg, be provided with cavity, make guaranteeing under the prerequisite of steel pawl leg energising section area, the steel using amount that has reduced steel pawl leg, has not only guaranteed energising effect but also has saved resource.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, anode rod, 2, crossbeam, 3, steel pawl leg, 4, internal steel pawl leg, 5, steel cylinder, 6, boss, 7, conduction reinforced company fishplate bar.
