Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production design of special-shaped prebaked anodes for electrolytic aluminum, in particular to a special-shaped prebaked anode for electrolytic aluminum. Background Art
[0002] Special-shaped prebaked anode is a prebaked anode for aluminum electrolysis, and is used as the anode material of prebaked aluminum electrolytic cells. It is made of petroleum coke and asphalt coke as aggregates and coal tar as binder. The raw materials are processed into a carbon block through calcination, screening, proportioning, kneading and baking. In the electrolysis process, the prebaked anode not only acts as a conductor, but also participates in the electrochemical reaction, playing an important role in the production process of electrolytic aluminum.
[0003] In the production of prebaked anodes for electrolytic aluminum, the keyways of the two bowls often overlap during the production process, shortening the distance between the carbon bowls and easily causing cracks between the carbon block bowls, resulting in an increase in the scrap rate.
[0004] During the electrolysis process, since the anode carbon bowl is designed to be conical, when the steel claws for electrolytic aluminum are used to cast the carbon bowl ferrophosphorus, a gap is formed between the anode carbon bowl and the ferrophosphorus due to the principle of thermal expansion and contraction. During use, the steel claws for electrolytic aluminum and the anode carbon bowl are prone to detachment or falling, increasing the downtime and maintenance time of the aluminum electrolytic cell and the difficulty of personnel operation. At the same time, since the contact between the anode carbon bowl and the ferrophosphorus is not dense, the power consumption during the electrolysis process will also increase, which will affect the normal production of electrolytic aluminum enterprises and increase production costs. Utility Model Content
[0005] The embodiment of the utility model provides a special-shaped prebaked anode for electrolytic aluminum to solve the above-mentioned technical problems.
[0006] The embodiment of the utility model adopts the following technical scheme: it includes a steel claw member for electrolytic aluminum and a pre-baked anode member used as anode material for a pre-baked aluminum electrolytic cell, the pre-baked anode member is provided with a plurality of anode carbon bowls, the anode carbon bowl is provided with a slot matching the steel claw member for electrolytic aluminum, the slot is radially provided with a second transverse groove, and the cast ferrophosphorus material forms a transverse concave-convex connection point between the steel claw member for electrolytic aluminum and the second transverse groove on the anode carbon bowl for electrolytic aluminum, so that the connection between the two is more stable.
[0007] Furthermore, an overflow trough is provided between two adjacent slots for the pouring material to flow over the two adjacent slots. Excess ferrophosphorus material will flow into the adjacent slots, thereby reducing the overflow of ferrophosphorus material and its connection with the surface of the pre-trained anode component, and also effectively saving the use of ferrophosphorus material.
[0008] Furthermore, a plurality of the anode carbon bowls are linearly arranged and equidistantly arranged along the pre-cultured anode member in order to better connect the anode carbon bowl with the steel claw member for electrolytic aluminum.
[0009] Furthermore, the steel claw member for electrolytic aluminum is provided with a plurality of No. 1 transverse grooves, and the plurality of No. 1 transverse grooves are arranged along the axial direction of the steel claw member for electrolytic aluminum. Different numbers of No. 1 transverse grooves can be arranged according to actual usage.
[0010] Furthermore, there are a plurality of the second transverse grooves, and the plurality of the second transverse grooves are arranged along the axis direction of the groove. Different numbers of the second transverse grooves can be arranged according to actual usage.
[0011] Furthermore, the steel claw for electrolytic aluminum is movably plugged into the slot, and the radius of the steel claw for electrolytic aluminum is smaller than the radius of the slot, so that the ferrophosphorus material can be better cast into the gap between the steel claw for electrolytic aluminum and the slot.
[0012] At least one of the above technical solutions adopted in the embodiment of the utility model can achieve the following beneficial effects:
[0013] In the utility model, a second transverse groove is opened in the groove position on the anode carbon bowl. When ferrophosphorus is poured between the steel claw member for electrolytic aluminum and the pre-cultivated anode member, the ferrophosphorus material flows into the gap between the steel claw member for electrolytic aluminum and the groove position, and a transverse concave-convex connection point is formed between the steel claw member for electrolytic aluminum and the second transverse groove on the anode carbon bowl for electrolytic aluminum. When the steel claw member for electrolytic aluminum lifts the pre-cultivated anode member longitudinally, under the action of the second transverse groove and the ferrophosphorus material, the connection state between the two is more stable and the contact is more dense.

At the same time, when the steel claw member 1 for electrolytic aluminum is moved, the pre-trained anode member 2 moves accordingly. The above is the working principle of the prior art structure of the utility model. The problem to be solved by the utility model is that when ferrophosphorus is poured in the gap between the steel claw member 1 for electrolytic aluminum and the anode carbon bowl 3, a gap is formed between the anode carbon bowl 3 and the ferrophosphorus due to the principle of thermal expansion and contraction, and the steel claw member 1 for electrolytic aluminum and the anode carbon bowl 3 are prone to detachment or falling during use.
[0026] Preferably, it comprises a steel claw member 1 for electrolytic aluminum, a pre-baked anode member 2 used as anode material for a pre-baked aluminum electrolytic cell, a plurality of anode carbon bowls 3 are arranged on the pre-baked anode member 2, a slot 4 matching the steel claw member 1 for electrolytic aluminum is opened inside the anode carbon bowl 3, a second transverse slot 5 is radially opened inside the slot 4, there are a plurality of second transverse slots 5, and the plurality of second transverse slots 5 are arranged along the axial direction of the slot 4, when the steel claw member 1 for electrolytic aluminum is inserted into the slot 4 on the anode carbon bowl 3, by pouring ferrophosphorus material into the position between the steel claw for electrolytic aluminum and the slot 4, the ferrophosphorus material is in liquid state when invading the slot 4, and the liquid ferrophosphorus material will flow into the second transverse slot 5 in the slot 4 and fill the second transverse slot 5, after the ferrophosphorus material is left standing for a period of time, the ferrophosphorus material The material gradually solidifies, at this time the ferrophosphorus material connects the steel claw 1 for electrolytic aluminum and the anode carbon bowl 3, and because the ferrophosphorus material is consistent with the shape of the second transverse groove 5, when the ferrophosphorus material connects the steel claw 1 for electrolytic aluminum and the anode carbon bowl 3, the ferrophosphorus material also forms a connected and engaged state with the second transverse groove 5, and a transverse concave-convex connection point is formed between the steel claw 1 for electrolytic aluminum and the second transverse groove 5 on the anode carbon bowl 3 for electrolytic aluminum, thereby improving the tightness of the casting connection between the pre-trained anode part 2 and the steel claw 1 for electrolytic aluminum, so that when the steel claw 1 for electrolytic aluminum lifts the pre-trained anode part 2, due to the state between the ferrophosphorus material and the second transverse groove 5, the steel claw 1 for electrolytic aluminum and the pre-trained anode part 2 will not easily separate or fall off.
[0027] Preferably, an overflow groove 6 is opened between two adjacent slots 4 for pouring materials to flow on the two adjacent slots 4. When pouring ferrophosphorus material inside the slots 4, excess ferrophosphorus material will flow into the adjacent slots 4, reducing the overflow of ferrophosphorus material and its connection with the surface of the pre-trained anode member 2, while also effectively saving the use of ferrophosphorus material.

When the steel claw member 1 for electrolytic aluminum lifts the pre-trained anode member 2, the No. 1 transverse grooves 100 can effectively reduce the ferrophosphorus material from falling off the steel claw member 1 for electrolytic aluminum.
[0030] Preferably, the steel claw member 1 for electrolytic aluminum is movably plugged into the slot 4, and the radius of the steel claw member 1 for electrolytic aluminum is smaller than the radius of the slot 4. Since the ferrophosphorus material for casting needs to be cast through the gap between the steel claw member 1 for electrolytic aluminum and the slot 4, the radius of the steel claw member 1 for electrolytic aluminum is smaller than the radius of the slot 4, which can better cast the two.
