Description
Technical field
The utility model belongs to the technical field of aluminium cell anode, is specifically related to a kind of structure of the double anode linker of using for large-scale aluminum electrolytic cell.
Background technology
Scale along with aluminium cell develops to maximization and large direction in recent years, and anode dimension that is adopted and weight are all increasing, have made that whole anode projecting length and area are excessive, thereby causes the unit surface production capacity of electrolyzer to reduce.On the other hand, the increase of anode quantity is changed the anodic workload and is also increased thereupon, and production cost increases.
In order to address the above problem, the double anode structure has appearred.Chinese patent CN01206021.6 discloses a kind of double anode structure, and every anode adopts 4 pawl heads to fix, and 4 pawl heads then are Roman numerals by one
Shape steel pawl is fixed.Steel pawl top is affixed with anode rod.Chinese patent CN03213604.8 also discloses a kind of bianode linker structure, this patent is thought the double anode structure of 4 pawl heads, cause the ionogen at position between the steel pawl to be difficult to cleaning, after carrying too much electrolytical anode scrap secretly and entering charcoal piece pressure-off operation, can reduce new anodic quality.This patent changes double anode into 3 pawl heads, and its steel pawl constitutes the M shape structure that lacks horizontal stroke, and promptly the steel pawl does not have steel crossbeam along its length.Yet the structure of this steel pawl (anode linker) analyzes its intensity from mechanics and will reduce greatly, and the steel pawl is stressed obviously inhomogeneous, and concerning large-scale and ultra-large type aluminium cell, its safe reliability and work-ing life all can have problems.
The utility model content
The purpose of this utility model is to seek the double anode steel pawl that a kind of confession is large-scale and the ultra-large type aluminium cell is used, guaranteeing that anode steel jaw has enough intensity and stressed uniform while of steel pawl, guarantees that the distribution of current in all steel pawls is even in each anode group again, to guarantee in the anode carbon block that distribution of current evenly and reduce volts lost.
Large-scale aluminum electrolytic cell anode steel jaw provided by the utility model comprises crossbeam and pawl head, it is characterized in that: crossbeam is made of two cross bearers, two oblique beams and four needle beams, wherein: (A) cross bearer be horizontal Roman numerals after oblique beam is connected
Shape; (B) the needle beam middle part is vertically affixed with the cross bearer termination; (C) bending downwards of needle beam two ends is connected to the pawl head.
The cast steel one-step casting moulding of the cross bearer of anode steel jaw of the present utility model, oblique beam, needle beam and pawl head.
Its top of anode steel jaw of the present utility model is positioned at two oblique beams peaces with the tie point of anode rod and connects the centre, and both are fixing by aluminum steel transition weldering welding.The pawl head then with charcoal piece Joint.
Anode steel jaw of the present utility model is made up of cross bearer, oblique beam, needle beam and pawl head four parts, and cross bearer has the function that strengthens integral mechanical structure intensity again in load-bearing, conduction; Oblique beam since with the cross bearer composition triangular structure that is connected as a single entity, integrally-built anti-twist ability is strengthened greatly; Needle beam then can reach the equally distributed purpose of adjacent two pawl head currents.
Anode steel jaw of the present utility model fully takes into account the stressed uniform requirement of steel pawl, adopts direction symmetrical structure in length and breadth, both provides convenience for residual anode pressure-disengaging and ferrophosphorus ring pressure-off in the future, takes into account the intensity and the uniform requirement of distribution of current of steel pawl again.The probability that this steel pawl in use is out of shape reduces greatly, and safety of structure and stability are splendid, and prolong work-ing life greatly, thereby has reduced the workload of steel pawl maintenance.Meanwhile, steel pawl of the present utility model has been realized the uniform distribution of electric current to greatest extent, so be particularly suitable for using on the large-scale and ultra-large type aluminium cell, can obtain bigger economic benefit.
Description of drawings

Fig. 2 is the anode steel jaw schematic top plan view;
Fig. 3 is an anode group structural representation.
1 is cross bearer among the figure, and 2 is oblique beam, and 3 is needle beam, and 4 is the pawl head, and 5 is anode rod, and 6 is anode carbon block.A is the distance (starting at from the center of needle beam) at cross bearer two ends among Fig. 2, and B is the between centers of needle beam.
Embodiment
Be further described below in conjunction with structure, the manufacturing of accompanying drawing anode steel jaw of the present utility model.
As shown in Figure 1, two oblique beams 2 by two cross bearers 1 and arranged crosswise constitute the horizontal Roman numerals
Shape, connect a needle beam 3 at the two ends of every cross bearer, the middle part of needle beam vertically is fixed as one with the cross bearer end, its two ends then bending downwards are connected with pawl head 4, so an anode steel jaw has eight pawl heads, pawl head bottom and charcoal piece 6 Joints have so just constituted large-scale and the aluminum electrolyzing cell used double anode structure of ultra-large type.When above-mentioned steel pawl is made, its cross bearer, oblique beam, needle beam and pawl head adopt the moulding of cast steel one-step casting, the tie point of steel pawl and anode rod then is positioned at the centre of two oblique beam handing-over, and it welds welding fabrication with then adopting the aluminum steel transition being connected of anode rod 5.
