Abstract
The utility model provides an aluminum electrolyte cell cathode busbar connecting device, which comprises a cathode steel bar, a copper-aluminum explosive welding block, a bolt, a nut, a soft busbar band and a cathode busbar, and is characterized in that the cathode steel bar and the copper-aluminum explosive welding block are lap contacted with a long strip type hole. When the cathode steel bar and the copper-aluminum explosive welding block are tightly fixed by the bolts and the nuts, which has full regulation margin exists, thus easily eliminating the resetting error occurred in the resetting of the aluminum electrolyte cell. The structure of the connecting device of the aluminum electrolyte cell appears simple, but plays a huge role in the actual production of the aluminum industry.
Description
Technical field
The utility model belongs to the technical field of aluminum cell structure, is specifically related to the coupling device between a kind of aluminium electrolytic cell cathode bus and the cathode steel bar.
Background technology
Aluminium cell is arranged in series usually in potroom, in the large-scale aluminium manufacturer its working current of the electrolyzer that adopts reach 300～500KA, magneticstrength on every side is very big.When indivedual electrolyzers need overhaul in the workshop, be whole taking-up the sequence from electrolyzer with the electrolyzer of overhaul, to transport to heavy repair department and repair, the electrolyzer that overhaul is good then installs back its original position again in time, to put into production.In the aforesaid operations process, more loaded down with trivial details operation is exactly that electric tank cathode rod iron and the negative busbar around it are disconnected, and newly the cathode steel bar and the groove negative busbar on every side of electrolyzer reconnect.Past all is to adopt welding process between cathode steel bar and the negative busbar, and the welding job amount is big, carries out welding operation simultaneously in the potroom of ordinary production, owing to be subjected to the influence of high-intensity magnetic field, electric arc and metal melt all can't be stablized, and work difficulty is bigger.Some have appearred recently about replacing the patented technology that welding process connects cathode aluminium busbar and cathode steel bar with crimping (or riveted joint) mode, as ZL200420030010.1.It is perforate on cathode steel bar, and sets up transition plate, connects soft band and connection piece with holes in the soft strap end portion of aluminium, by bolt, nut connection piece is crimped onto on the cathode steel bar.Because it still takes common bolt, nut to press the knot mode in the connection of cathode steel bar soft band connection piece with aluminium, thisly want to eliminate the electrolyzer deviation that resets fully by soft band of aluminium and the limited flexibility that is connected soft band, facts have proved it is unpractical.
The utility model content
The utility model purpose is to propose a kind of novel crimping mode, in the hope of solving the problem that has the deviation that resets when existing aluminium electrolytic cell cathode bus is connected with cathode steel bar.
Aluminium electrolytic cell cathode bus connecting device of the present utility model comprises cathode steel bar, copper al blasting welding block, bolt, nut, soft bus band, negative busbar, it is characterized in that:
(1) the cathode steel bar outer end has in order to rod iron is fixed on the long strip shape hole on the copper al blasting welding block;
(2) copper al blasting welding block front end also has corresponding long strip shape hole;
(3) copper al blasting welding block is welded in the front end of soft bus band, and the soft bus band the other end then is welded on the negative busbar.
The long strip shape hole opened of the utility model on cathode steel bar can be rectangular; Also can be oblong.Because it can allow the translation therein of bolt, nut, so can eliminate the transverse excursion between negative busbar and the electrolyzer corresponding position, the soft bus band then elevation between available buffer negative busbar and the electrolyzer is offset.Just well solved the reset problem of deviation of electrolyzer by so simple design.
Characteristics of the present utility model are that adding a soft bus band with a long strip shape hole can realize that cathode steel bar is connected with the detachable of negative busbar, and are that the displacement that may occur between electrolyzer and the negative busbar is allowed some leeway.
Aluminium electrolytic cell cathode bus connecting device of the present utility model, the long strip shape hole of being opened on its copper al blasting welding block can parallel with the hole on the cathode steel bar; Also can be perpendicular with the hole on the cathode steel bar.Adjustable surplus ground like this, between the two can be bigger.
Description of drawings
Fig. 1,2, the 3rd, the structural representation of aluminium electrolytic cell cathode bus connecting device of the present utility model.
Fig. 4,5,6 is the actual connection diagram of the utility model negative busbar coupling device.Among the figure: 1 cathode steel bar; 2 bronze medal al blasting welding blocks; 3 soft bus bands; 4 negative busbars; 5 bolts; 6 nuts; 7 pads; 8 holes.
Embodiment
Below in conjunction with accompanying drawing aluminium electrolytic cell cathode bus connecting device of the present utility model is further described and replenishes.
Embodiment 1
As shown in Figure 1, this is that soft bus band 3 levels are bent upwards the situation that is welded on negative busbar 4 bottoms, has two oblong holes 8 on cathode steel bar 1, also has corresponding oblong hole 8 on the soft bus band front end copper al blasting welding block 2.As shown in Figure 4, when electrolyzer resets, the copper al blasting welding block that originally is fixed on negative busbar and the soft bus band is ridden on the cathode steel bar, hole on both is roughly alignd, pass bolt 5, cover Upper gasket 7 and nut 6, regulate cathode steel bar and negative busbar relative position between the two, up to final torsion and pulling force completely dissolve, at this moment, i.e. the deviation that resets has been eliminated in explanation.Last tightening nuts is finished being connected between cathode steel bar and the negative busbar.
As shown in Figure 2, this is that soft bus band 3 levels are bent downwardly the situation that is welded on negative busbar 4 tops, opens two orthogonal holes 8 on cathode steel bar 1, corresponding also having and its vertical oblong hole 8 on the soft bus band front end copper al blasting welding block 2.As shown in Figure 5, when electrolyzer resets, the copper al blasting welding block that originally is fixed on negative busbar and the soft bus band is ridden on the cathode steel bar, both are roughly alignd at the hole center, pass bolt 5, cover Upper gasket 7 and nut 6, regulate the relative position between cathode steel bar and the negative busbar, until torsion and pulling force completely dissolve, illustrate that the deviation that resets eliminates, tightening nuts is finished being connected between cathode steel bar and the negative busbar again.
Shown in Fig. 3,6, this is that soft bus band 3 fillet welding in the vertical positions are connected on the combination crimping form on the negative busbar.All the other structures and embodiment 1,2 are basic identical, here repeated description no longer just.
In a word, the utility model changes the circular hole on the copper al blasting welding block on cathode steel bar and the negative busbar into slotted hole, and making has had bigger adjusting leeway between the two, like this, when electrolyzer resets, is easy to eliminate the deviation that resets.Design of the present utility model seems simply, but can bring into play enormous function in the aluminum smelting industry practice.
