Description
Technical field
The utility model relates to electrolytic aluminum anode steel pawl technical field.
Background technology
The Main Function of anode steel claw for aluminum electrolysis in Aluminium Electrolysis process is conduction, anode steel jaw is cast steel, need to be connected with aluminium guide bar by steel-aluminum explosive weld block, concrete syndeton is: the Plate Welding of anode steel jaw upper weld inclined-plane and steel-aluminum explosive weld block, and aluminium guide bar welding inclined-plane welds with the aluminium sheet of steel-aluminum explosive weld block.
In electrolyzer normal productive process, anode carbon block group temperature after putting into electrolyzer rises, final steel pawl and charcoal deblocking temperature reach 400 DEG C and 900 DEG C respectively, due to larger than the thermal expansivity of charcoal block about 4 times of the thermal expansivity of the steel of steel pawl, therefore the swell increment of steel pawl is greater than anode carbon block, causes anode carbon block charcoal bowl generation deformation, and the stress due to deformation generation is greater than the permissible stress of charcoal block, thus cause anode carbon block to crack, even rupture.
Utility model content
Technical problem to be solved in the utility model is the technical deficiency for above-mentioned existence, and provide a kind of electrolytic aluminum anode steel pawl, it is connected with anode carbon block reliably, can the extruding of antianode charcoal block after expanded by heating, prevents anode carbon block crackle or fracture.
The technical solution adopted in the utility model is: provide a kind of electrolytic aluminum anode steel pawl, comprises top shunting platform, and the upper weld of top shunting platform has steel-aluminum explosive weld block; The portion integral of top shunting platform is provided with equally distributed at least two claw bars; The bottom of each claw bar is the insertion rod vertically arranged; Platform shunted by each claw bar part from insertion rod to top is tilting bar; The angle of tilting bar and vertical direction is 30 ° to 60 °; In the bottom of top shunting platform, between two often adjacent claw bars, all have the anti-expansion groove of vertical direction.
Further optimization the technical program, the shape of the cross section of each insertion rod of electrolytic aluminum anode steel pawl is twisted star.
Further optimization the technical program, electrolytic aluminum anode steel pawl is parallel three-jaw or parallel four paws.
Further optimization the technical program, electrolytic aluminum anode steel pawl is the wherein one of three-dimensional four paws, three-dimensional six pawls, three-dimensional eight pawl threes.
The beneficial effects of the utility model are: 1, the claw bar of conventional anode steel pawl is divided into the insertion rod of vertically setting and the vertically disposed crossbeam of insertion rod to form, after crossbeam is heated, lateral length increases, because the thermal expansivity of anode carbon block is less than insertion rod, such insertion rod will draw anode carbon block outward, thus causes anode carbon block crackle or fracture.The out-of-level setting of tilting bar of the present utility model, after expanded by heating, under the promotion of anti-expansion groove, the deformation being easily transformed into vertical direction of horizontal direction, and the height increase of vertical direction can make insertion rod more firmly with anode carbon block electrical contact.2, the cross section of insertion rod is twisted star, the easy pressurized deformation of this shape, when anode carbon block and insertion rod be heated both ratio of expansion different time, the insertion rod of twisted star can adapt to nonsynchronous expansion, can ensure that electrical contact is good, both volume change can be adapted to again, prevent anode carbon block crackle broken further.3, Structure adaptation of the present utility model is wide general, and this structure can be applied in all kinds of anode steel jaw.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation in another direction of Fig. 1.
In figure, 1, top shunting platform; 2, steel-aluminum explosive weld block; 3, claw bar; 4, insertion rod; 5, tilting bar; 6, anti-expansion groove.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the electrolytic aluminum anode steel pawl of the present embodiment to three-dimensional four paws structure is described.
Electrolytic aluminum anode steel pawl comprises top shunting platform 1, and the upper weld of top shunting platform 1 has steel-aluminum explosive weld block 2; The portion integral of top shunting platform 1 is provided with equally distributed at least two claw bars 3; The bottom of each claw bar 3 is the insertion rod 4 vertically arranged; Each claw bar 3 is tilting bar 5 from the part of insertion rod 4 to top shunting platform 1; Tilting bar 5 is 30 ° to 60 ° with the angle of vertical direction; In the bottom of top shunting platform 1, between two often adjacent claw bars 3, all have the anti-expansion groove 6 of vertical direction; The shape of the cross section of each insertion rod 4 is twisted star.
The out-of-level setting of tilting bar 5 of the present utility model, after expanded by heating, the gap of anti-expansion groove 6 reduces, the deformation of horizontal direction is transformed into the deformation of vertical direction, namely shunting platform 1 in top raises, and top shunting platform 1 upper end and conductive bar fix, the height increase of such vertical direction can make insertion rod 4 be subject to downward power, downward reactive force can make insertion rod 4 more securely with anode carbon block electrical contact.
The cross section of insertion rod 4 is twisted star, the easy pressurized deformation of this shape, when anode carbon block and insertion rod 4 be heated both ratio of expansion different time, the fin reversing surrounding in star structure inwardly compresses, the radial swelling of insertion rod 4 can be alleviated, can ensure that electrical contact is good, both volume change can be adapted to again, prevent anode carbon block crackle broken.
