Description
TECHNICAL FIELD
[0001] The utility model relates to electrolytic aluminium technical field, specifically a kind of prebaked anode. BACKGROUND
[0002] In the anode assembly stage of electrolytic aluminium production, phosphorus pig iron is needed to be poured in the gap between steel claw and carbon bowl, so that it is connected together to constitute carbon block group. At present, in order to improve the bonding strength of prebaked anode and steel claw, several anti-disengagement grooves are often machined on the side wall of the carbon bowl of prebaked anode. Figure 2 As shown in the figure.
[0003] Although this way can increase the contact area between phosphorus pig iron and carbon bowl, thereby improving the bonding strength of prebaked anode and steel claw to some extent, but during the subsequent carbon block group transport process, due to vibration, gap is easily generated at the connection between steel claw and anode carbon bowl, and in addition, the existing anti-disengagement groove extends along the axial direction of carbon bowl, so the gap is easily expanded, thereby causing the connection between steel claw and prebaked anode to loosen, and seriously even causing disengagement, which leads to serious quality accidents. SUMMARY
[0004] In view of the above problems, the prebaked anode provided by the present application can effectively improve the connection reliability between prebaked anode and steel claw.

[0011] Further, the side surface of the carbon bowl is formed by a plurality of planes connected end to end, and the connection between adjacent two planes forms an edge.
[0012] Further, the edge of the side surface of the carbon bowl is rounded.
[0013] Further, the number of anti-disengagement grooves is equal to the number of planes, and one-to-one correspondence exists.
[0014] Further, the opening of the communication channel is located on the edge of the side surface of the carbon bowl.
[0015] Further, the carbon bowls are arranged in a line.

[0018] The present application has the following beneficial effects:
[0019] The prebaked anode provided by the embodiment of the present application is provided with an anti-disengagement spiral chute in a spiral shape on the side wall of the carbon bowl of the prebaked anode. When the steel claw is connected to the prebaked anode through the phosphorus pig iron water, a spiral limiting structure can be formed in the anti-disengagement spiral chute.

[0032] In order to make the person skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be described in detail below in combination with the drawings in the embodiments of the present application, and the described embodiments are only some of the embodiments of the present application, but not all the embodiments. All other embodiments obtained by the person skilled in the art without creative labor on the basis of the embodiments of the present application shall belong to the protection scope of the present application.
[0033] In order to facilitate the understanding of the specific embodiments of the present application, the coordinate system is defined as shown in Figure 1 , and the left-right direction is taken as the horizontal direction, the front-rear direction is taken as the vertical direction, and the up-down direction is taken as the vertical direction.
[0034] As shown in Figure 1 and Figure 3 , a prebaked anode comprises an anode body 1, wherein a plurality of carbon bowls 11 are arranged on the anode body 1, and the plurality of carbon bowls 11 are arranged in a straight line along the horizontal direction according to the coordinate system shown in Figure 1 .
[0035] As a specific embodiment, the anode body 1 in the present embodiment is provided with four carbon bowls 11.
[0036] As shown in Figure 2 and Figure 4 , a plurality of anti-escape inclined grooves 111 are arranged on the side surface of the carbon bowl 11, the projection of the side surface of the carbon bowl 11 in the horizontal plane 1131 is a closed loop curve, and the plurality of anti-escape inclined grooves 111 are uniformly arranged along the closed loop curve. The central angle corresponding to the projection of the anti-escape inclined groove 111 in the horizontal plane 1131 is less than 20°.
[0037] As a specific embodiment, the side surface of the carbon bowl 11 in the present embodiment is provided with six anti-escape inclined grooves 111.
[0038] As a specific embodiment, the lower end of the anti-disengagement chute 111 extends to the bottom surface of the carbon bowl 11, and the upper end of the anti-disengagement chute 111 extends to the upper side surface of the anode body 1 and forms an opening.
[0039] As shown in Figure 2 and Figure 4 , the side surface of the carbon bowl 11 is provided with an anti-disengagement spiral chute 112 in a spiral structure.
[0040] By providing the anti-disengagement spiral chute 112 on the side surface of the carbon bowl 11, during the pouring of the phosphorus pig iron water, the phosphorus pig iron water will flow into the anti-disengagement spiral chute 112 and form a spiral limiting structure. The spiral limiting structure can limit the freedom of the prebaked anode to move up and down relative to the steel claw 2 (according to the coordinate system shown in Figure 1 ) so as to inhibit the expansion of the gap.
[0041] Further, as shown in Figure 2 , both ends of the anti-disengagement spiral chute 112 are blind ends, and the number of turns of the anti-disengagement spiral chute 112 is preferably greater than or equal to one turn.
[0042] As a specific embodiment, the number of turns of the anti-disengagement spiral chute 112 in this embodiment is one turn.
[0043] Further, as shown in Figure 5 , Figure 6 , Figure 7 and Figure 8 , a communication channel 12 is provided between adjacent two carbon bowls 11, and the adjacent two carbon bowls 11 are connected through the communication channel 12. Preferably, the communication channel 12 is located at the lower end of the carbon bowl 11.
[0044] By providing the communication channel 12, after pouring the phosphorus pig iron water, a connecting rod connecting the adjacent carbon bowls 11 will be formed in the communication channel 12, and the two ends of the connecting rod are respectively formed as a whole with the phosphorus pig iron water solidified between the carbon bowl 11 and the steel claw 2 gap. In this way, the probability of loosening can be effectively reduced, and the occurrence of the serious quality accident of disengagement can be avoided.
[0045] Further, as shown in Figure 2 , Figure 3 and Figure 5 , the side surface of the carbon bowl 11 is formed by a plurality of planes 1131 connected in sequence, the connection between adjacent two planes 1131 forms an edge 1132, and the projection of the carbon bowl 11 on the horizontal plane 1131 is in a polygonal structure.
[0046] Further, the edge 1132 of the side surface of the carbon bowl 11 is rounded, so that the adjacent two planes 1131 are smoothly transitioned.
[0047] Furthermore, the number of anti-detachment grooves 111 is equal to the number of planes 1131, and they correspond one-to-one. The anti-detachment grooves 111 are located in the middle of the corresponding planes 1131.
[0048] In one specific embodiment, the side of the charcoal bowl 11 in this embodiment is formed by six planes 1131 connected end to end in sequence. The projection of the charcoal bowl 11 in the horizontal plane 1131 is a regular hexagonal structure, and an anti-detachment groove 111 is provided in the middle of each plane 1131.
[0049] Furthermore, such as Figure 8 , Figure 9 and Figure 10 As shown, the opening of the connecting channel 12 is located on the edge 1132 on the side of the charcoal bowl 11.
[0050] The reason for this design is that there is an increased gap between the edge 1132 on the side of the charcoal bowl 11 and the steel claw 2. This allows the air in the connecting channel 12 to be discharged smoothly through the gap when the molten iron is poured, so that the molten iron can fill the connecting channel 12 smoothly and avoid creating voids in the formed connecting rod, which would affect the connection strength.
[0051] Other embodiments obtained by those skilled in the art based on the embodiments provided in this application by combining, splitting, or reorganizing the embodiments of this application do not exceed the protection scope of this application.
[0052] The above detailed embodiments have provided a detailed explanation of the purpose, technical solutions, and beneficial effects of the embodiments of this application. The above are merely specific embodiments of the embodiments of this application and are not intended to limit the protection scope of the embodiments of this application.
