Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic copper foil production equipment, in particular to an anode tank structure of an electrolytic copper foil production machine. Background Art

[0002] The all-graphite cathode electrolytic cell lining utilizes a paste-tie design around the cathode. The paste is used to secure the cathode carbon blocks around the bottom of the cell and the anti-seepage material. This lining design helps reduce cracks in the cathode carbon blocks and prolongs the cell life. The castable material around the cell is poured using a formwork method. The formwork is first supported, then the castable is mixed to a specific water ratio and directly cast. The formwork is removed after the castable solidifies. The castable material in the electrolytic cell lining primarily prevents leakage of molten aluminum or electrolyte. To reduce leakage at the connection between the cement paste and the cathode carbon block assembly, some cathode surfaces are also designed with anti-seepage grooves. However, since the castable support formwork lacks an anti-seepage groove, the castable surface also lacks one. The cathode paste and castable are joined flat, which hinders adhesion and can lead to aluminum penetration at the connection between the paste and castable. This structural design flaw is a common example. For example, patent CN217869122U discloses a lining device for large prebaked electrolytic cells. Utility Model Content

[0009] An electrolytic cell with an anti-seepage trough formed based on the above-mentioned castable anti-seepage trough construction device includes a trough wall structure, a trough bottom structure, a cathode steel rod, a cathode carbon block, etc. The castable is burned on the trough wall structure through a template, and a plurality of concave anti-seepage grooves are formed on the inner surface of the castable by the castable anti-seepage trough construction device. After the cathode paste is fixed and formed, a plurality of protrusions matching the anti-seepage grooves are formed, and the protrusions are embedded in the corresponding anti-seepage grooves so that the cathode paste and the castable form a mutually interlocking bonding structure.

[0010] Furthermore, an anti-seepage groove is also provided on the side of the cathode carbon block opposite to the cathode paste, and a bonding structure in which the anti-seepage groove and the protrusion are interlocked is formed between the cathode paste and the cathode carbon block.

[0017] In this embodiment, refer to Figure 1 and Figure 2 The castable anti-seepage trough construction device includes a template 1, and a plurality of groove rods 2 are arranged on the side of the template 1 facing the castable. The groove rods 2 protrude from the surface of the template 1, and the groove rods 2 are vertically spaced apart from each other, that is, they are arranged at intervals up and down.

[0018] The slot rods 2 are evenly arranged horizontally, and the spacing between adjacent slot rods 2 is the same and is 1-3 times the diameter of the slot rod 2 itself.

[0019] The slot rods 2 are made of round steel with a diameter of 3-5 mm, for example, 4 mm, with a spacing of 5 mm. The length of the slot rods 2 is the same as that of the template 1.

[0020] The template 1 is made of steel plate, and the slot rods 2 are fixed to the surface of the template 1 by welding.

[0021] A clearance hole 11 corresponding to the cathode steel rod 4 of the electrolytic cell is provided at the bottom of the template 1 . After the template 1 is installed, the cathode steel rod 4 is embedded in the clearance hole 11 , or in other words, the cathode steel rod 4 passes through the clearance hole 11 .

[0022] Reference Figure 3 The electrolytic cell with an anti-seepage groove formed based on the above-mentioned castable anti-seepage groove construction device includes a groove wall structure, a groove bottom structure 3, a cathode steel rod 4, a cathode carbon block 5, etc. The castable 6 is burned on the groove wall structure through the template 1, and a plurality of concave anti-seepage grooves 8 are formed on the inner surface of the castable 6 by the castable anti-seepage groove construction device. After the cathode paste 7 is fixed and formed, a plurality of protrusions matching the anti-seepage grooves 8 are formed, and the protrusions are embedded in the corresponding anti-seepage grooves 8, so that the cathode paste 7 and the castable 6 form a mutually interlocking bonding structure, thereby improving the bonding strength and anti-seepage ability.

[0023] An anti-seepage groove is also provided on the side of the cathode carbon block 5 facing the cathode paste 7 , and a bonding structure in which the anti-seepage groove and the protrusion are interlocked is formed between the cathode paste 7 and the cathode carbon block 5 .

[0024] The anti-seepage groove 8 is an arc-shaped groove, which can increase the contact area between the castable 6 and the cathode paste 7. At the same time, the anti-seepage groove 8 is conducive to the aluminum liquid to circle back during penetration, thereby increasing the flow resistance, reducing the aluminum liquid from scouring the leakage gap, creating conditions for the aluminum liquid to solidify as soon as possible, reducing the area of ​​the damaged part, and ultimately achieving the effect of eliminating leakage and extending the life of the electrolytic cell.

[0025] During pouring, first apply a layer of engine oil to the side of the template 1 facing the castable 6 and the surface of the slot rod 2 to facilitate demolding of the template 1 after the castable 6 is formed. Then, pour the castable 6 with a certain amount of moisture between the template 1 and the insulation bricks on the side of the electrolytic cell, and use a vibrating rod to compact it and then level the height of the castable 6. Cover it with a plastic film to retain moisture and allow it to cure. After the curing period, remove the template 1. At this time, an anti-seepage groove 8 is formed on the surface of the castable 6. Thereafter, the cathode paste 7 is fixed in the gap between the castable 6 and the cathode carbon block 4, so that when the cathode paste 7 is fixed, not only an anti-seepage groove and a protrusion are interlocked with each other on the surface of the cathode carbon block 4, but also an anti-seepage groove and a protrusion are interlocked with each other on the surface of the castable 6 and the cathode paste 7, thereby increasing the contact area, making the bonding more firm, and enhancing the anti-seepage effect.

[0026] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
