[0002] During the replacement of anodes in an aluminum electrolysis cell, it is usually necessary to cover the new anode with anode cover material. However, due to the design of the aluminum electrolysis cell's discharge point, the side of the new anode closest to the discharge point is prone to exposure after entering the cell, resulting in anodizing loss. In related technologies, operators sometimes use a special mold to separate the anode from the discharge point, and fill the space between the mold and the anode with alumina fragments and molten aluminum electrolyte to form an adhesive layer on the side of the anode closest to the discharge point. Then, a layer of alumina is coated onto this adhesive layer to protect the side of the anode closest to the discharge point. However, this protective method involves a large amount of manual labor, and the molten aluminum electrolyte is at a high temperature, posing significant safety hazards to operators during operation.

Detailed Implementation

[0044] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0045] like Figures 1 to 9 As shown, according to a first aspect of the present disclosure, an anti-oxidation device 100 for an anode carbon block in an aluminum electrolytic cell is provided, comprising: a connecting rod portion 110 for being fixedly disposed on the top end of the anode carbon block 100' to be protected; and a cover plate portion 120 connected to one end of the connecting rod portion 110. The anode carbon block 100' to be protected has a first sidewall 101', which is arranged close to the feeding area 201' of the aluminum electrolytic cell 200'. The cover plate portion 120 is fixedly disposed on the anode carbon block 100' to cover at least a portion of the first sidewall 101'.

[0046] The anti-oxidation device 100 for anode carbon blocks in an aluminum electrolytic cell provided in this embodiment includes the aforementioned connecting rod portion 110 and the aforementioned cover plate portion 120. One end of the connecting rod portion 110 is connected to the aforementioned cover plate portion 120. In practical applications, the connecting rod portion 110 is used to fix the top of the anode carbon block 100' to be protected, and the cover plate portion 120 is used to fix the anode carbon block 100' to be protected, thereby achieving the installation and fixation of the anti-oxidation device 100, reducing the risk of the anti-oxidation device 100 shifting after installation, and helping to ensure the relative positional stability between the anti-oxidation device 100 and the anode carbon block 100' to be protected; the cover plate portion 120 is fixedly disposed on the anode carbon block 100' to be protected. In case of 0', at least a portion of the first sidewall 101' of the anode carbon block 100' to be protected can be covered. The first sidewall 101' is the side of the anode carbon block 100' to be protected that is close to the feeding area 201' of the aluminum electrolysis cell 200'. In case of leakage of anode covering material at the first sidewall 101', the cover plate 120 can cover at least a portion of the first sidewall 101' to reduce the risk of large-scale exposure of the first sidewall 101' and help reduce the oxidation loss of the anode carbon block. Furthermore, based on the aforementioned configuration, the aluminum electrolytic cell anode carbon block anti-oxidation device 100 provided in this embodiment is suitable for installation on the corresponding anode carbon block 100' to be protected before it enters the cell. This reduces the protective operations performed by operators after the anode carbon block 100' enters the cell, and eliminates the need for operators to apply molten aluminum electrolyte to the anode carbon block 100'. This improves the safety of the anti-oxidation operation and helps reduce the labor costs and risks associated with the anti-oxidation operation.

[0047] It should be noted that, Figure 3 , Figure 6 and Figure 9 A portion of the aluminum electrolysis cell 200' is schematically shown in the figure.

[0048] It should be noted that during the replacement of the anode in the aluminum electrolysis cell 200', it is usually necessary to cover the anode carbon block of the new anode with anode cover material. However, due to the setting of the feeding point of the aluminum electrolysis cell 200', after the new anode is placed in the cell near the feeding area 201', the anode carbon block of the new anode near the feeding area 201' is prone to the phenomenon of anode cover material falling off and being lost, resulting in partial exposure of the anode and thus loss of anode oxidation. In related technologies, operators sometimes use a special mold to separate the anode carbon block from the feeding point, and fill the space between the mold and the anode carbon block with alumina crushed material and molten aluminum electrolyte to form an adhesive on the side of the anode carbon block near the feeding point. Then, a layer of alumina is coated on the adhesive to protect the side of the anode near the feeding point. However, the above-mentioned protection method involves a large amount of manual work, and the temperature of the molten aluminum electrolyte is high, posing significant safety hazards to operators during operation. Compared to the aforementioned protection methods, the anti-oxidation device 100 for anode carbon blocks in the aluminum electrolytic cell provided in this embodiment can be installed on the corresponding anode carbon block 100' to be protected before it enters the cell. That is, the assembly operation between the anti-oxidation device 100 and the anode carbon block 100' is suitable to be carried out outside the cell, thereby reducing the protective operations of the operator after the anode carbon block 100' enters the cell. Moreover, it eliminates the need for the operator to apply molten aluminum electrolyte to the anode carbon block 100', which can improve the safety of the anti-oxidation operation and reduce the labor cost and danger of the anti-oxidation operation. After installation, the anti-oxidation device 100 and the anode carbon block 100' can maintain good relative positional stability, thereby ensuring the covering effect of the cover plate 120 on the first sidewall 101' and reducing the risk of the anode carbon block 100' being exposed due to the anode covering material falling off the first sidewall 101'. This helps to prevent the oxidation of the anode carbon blocks in the feeding area 201' of the aluminum electrolytic cell 200'.

[0049] Understandably, during the replacement of the anode in the aluminum electrolysis cell 200', before the new anode is placed in the cell, the new anode that will be placed near the material feeding area 201' of the aluminum electrolysis cell 200' can be identified as the anode to be protected. Correspondingly, the anode carbon block of the anode to be protected is the anode carbon block 100'. Then, based on the preset placement position and posture of the anode carbon block 100' in the aluminum electrolysis cell 200', the first sidewall 101' of the anode carbon block 100' can be determined. Then, the anti-oxidation device 100 can be installed on the anode carbon block 100' so that the cover plate 120 covers at least part of the first sidewall 101'. After the anti-oxidation device 100 is installed, the corresponding new anode can be installed in the designated position in the aluminum electrolysis cell 200'.

[0050] It is understood that the aforementioned anode carbon block 100' to be protected may also have a second side wall, a bottom wall and a top wall. The aforementioned bottom wall and top wall are two opposite outer walls of the anode carbon block 100' to be protected in the height direction, and the position height of the aforementioned top wall is higher than that of the aforementioned bottom wall. Accordingly, the aforementioned connecting rod portion 110 can be set on the aforementioned top wall during use. The aforementioned first side wall 101' and the aforementioned second side wall are both located between the aforementioned top wall and the aforementioned bottom wall, and the distance between the aforementioned first side wall 101' and the aforementioned feeding area 201' is greater than the distance between the aforementioned second side wall and the aforementioned feeding area 201'. The number of the aforementioned first sidewall 101' and the aforementioned second sidewall is greater than or equal to one. Accordingly, the first sidewall 101' includes the sidewall of the anode carbon block 100' to be protected that is closest to the aforementioned feeding area 201', and the second sidewall includes the sidewall of the anode carbon block 100' to be protected that is furthest from the aforementioned feeding area 201'. When the number of the aforementioned first sidewall 101' is greater than one, at least one of the aforementioned anti-oxidation devices 100 can be installed on each first sidewall 101' to ensure the protective effect on the anode carbon block 100' to be protected. Alternatively, the aforementioned anti-oxidation device 100 can be installed only on the first sidewall 101' that is closest to the aforementioned feeding area 201' among the multiple aforementioned first sidewalls 101' to reduce the protection cost.

[0051] It is understood that the aforementioned cover plate portion 120 can completely cover the aforementioned first sidewall 101', or cover only a portion of the aforementioned first sidewall 101'. For example... Figure 3 , Figure 6 and Figure 9 As shown, when the cover plate portion 120 covers the aforementioned first sidewall 101', considering that the top area of ​​the aforementioned first sidewall 101' is more likely to be exposed, the cover plate portion 120 can be used to cover the top area of ​​the aforementioned first sidewall 101', that is, to cover the portion of the aforementioned first sidewall 101' near the aforementioned top wall.

[0052] Understandably, in practical applications, the aforementioned cover plate 120 can be attached to the aforementioned first sidewall 101' to avoid forming a large gap between the cover plate 120 and the first sidewall 101', which is beneficial to improving the anti-oxidation effect of the aforementioned anti-oxidation device 100 on the protected anode carbon block 100'. Correspondingly, if there is a gap between the cover plate 120 and the aforementioned first sidewall 101' during installation, anti-oxidation filler can be filled into the gap. The aforementioned anti-oxidation filler can include, but is not limited to, alumina and thermal insulation crushed material, thereby reducing the probability of the aforementioned first sidewall 101' coming into contact with air.

[0053] It is understood that there are various ways to fix the aforementioned cover plate 120 to the aforementioned anode carbon block 100' to be protected, such as by gluing or by using fasteners. The specific fixing method can be selected according to actual needs, and no further limitations are made here. Similarly, there are also various ways to fix the aforementioned connecting rod 110 to the aforementioned anode carbon block 100' to be protected. For example, it can be fixed by gluing or by using fasteners, or the connecting rod 110 and the top of the aforementioned anode carbon block 100' can be compacted with insulating material after the anode carbon block 100' is placed in the tank. The specific fixing method can be selected according to actual needs, and no further limitations are made here. Accordingly, when the connecting rod 110 is fixed to the aforementioned anode carbon block 100' to be protected, the connection relationship between the connecting rod 110 and the cover plate 120 can further improve the installation stability of the cover plate 120, reduce the risk of the cover plate 120 falling off, and provide a guarantee for the protective effect of the aforementioned anti-oxidation device 100.

[0054] In some examples, the link portion 110 includes an aluminum link, and the cover portion 120 includes an aluminum cover.

[0055] In this technical solution, the connecting rod portion 110 may include the aforementioned aluminum connecting rod, and the cover plate portion 120 may include the aforementioned aluminum cover plate. The aforementioned aluminum connecting rod can be used to be disposed at the top of the aforementioned anode carbon block 100' to be protected, and the aforementioned aluminum cover plate is connected to one end of the aforementioned aluminum connecting rod and is used to cover at least a portion of the aforementioned first sidewall 101'. Based on the aforementioned arrangement, on the one hand, the connecting rod portion 110 and the cover plate portion 120 can have relatively high structural strength, thereby reducing the risk of damage to the aforementioned anti-oxidation device 100 during use and facilitating the extension of the previous lifespan. The service life of the aforementioned anti-oxidation device 100 is extended; on the other hand, the materials of the connecting rod portion 110 and the cover plate portion 120 can be more adapted to the aluminum electrolysis production process, thereby reducing the risk of contaminating the aluminum electrolysis cell 200' of the aforementioned anti-oxidation device 100 after it is put into the cell along with the anode carbon block 100' to be protected, which is conducive to ensuring production quality; furthermore, the ease of sourcing materials for the aforementioned anti-oxidation device 100 can be improved, thereby reducing the manufacturing cost and operating cost of the anti-oxidation device and improving the manufacturing efficiency of the aforementioned anti-oxidation device 100.

[0056] In some examples, the connecting rod portion 110 and the cover plate portion 120 are integral structures.

[0057] In this technical solution, the connecting rod portion 110 and the cover plate portion 120 can be set as an integral structure. Based on the aforementioned setting, the connection reliability between the connecting rod portion 110 and the cover plate portion 120 can be improved, and the assembly difficulty between the connecting rod portion 110 and the cover plate portion 120 can be reduced. This is beneficial to reduce the manufacturing difficulty of the aforementioned anti-oxidation device 100 while ensuring the structural reliability of the aforementioned anti-oxidation device 100.

[0058] like Figures 3 to 6 and Figure 9 As shown, in some examples, the aluminum electrolytic cell anode carbon block anti-oxidation device 100 further includes: a connecting part 130, disposed on the cover plate part 120, for fixing the cover plate part 120 to the first side wall 101'.

[0059] In this technical solution, the aforementioned anti-oxidation device 100 may further include the aforementioned connecting portion 130; based on the aforementioned configuration, the aforementioned anti-oxidation device 100 can be connected to the first sidewall 101' of the aforementioned anode carbon block 100' to be protected through the aforementioned connecting portion 130, thereby achieving a fixed connection between the cover plate portion 120 and the aforementioned first sidewall 101', which is beneficial to improving the installation stability of the cover plate portion 120 and ensuring the covering effect of the cover plate portion 120 on the first sidewall 101', thereby providing a guarantee for the protective effect of the aforementioned anti-oxidation device 100.

[0060] like Figure 3 and Figure 9 As shown, in some examples, the connecting portion 130 includes a fastener 131 for connecting to the first sidewall 101' through the cover portion 120.

[0061] In this technical solution, the connecting part 130 may include the aforementioned fastener 131; based on the aforementioned configuration, the cover part 120 can be connected to the aforementioned first side wall 101' through the aforementioned fastener 131, thereby improving the installation stability of the cover part 120, ensuring the covering effect of the cover part 120 on the first side wall 101', providing a guarantee for the protective effect of the aforementioned anti-oxidation device 100, and fixing the aforementioned cover part 120 and the aforementioned first side wall 101' by fastening can also reduce the installation difficulty and installation cost of the cover part 120, which is conducive to further reducing the operation difficulty of operators and improving the execution efficiency of anti-oxidation operations.

[0062] It is understood that the aforementioned cover plate portion 120 may have a connection hole 121 for the aforementioned fastener 131 to pass through.

[0063] It is understandable that there may be multiple fasteners 131.

[0064] It is understood that the aforementioned fastener 131 can be, but is not limited to, fasteners such as pins, bolts, or screws.

[0065] like Figures 4 to 6 As shown, in some examples, the connecting portion 130 includes an adhesive layer 132 disposed on one side of the cover portion 120 for bonding to the first sidewall 101'.

[0066] In this technical solution, the connecting portion 130 may include the aforementioned adhesive layer 132. Based on the aforementioned configuration, the cover portion 120 can be bonded to the aforementioned first sidewall 101' via the adhesive layer 132. This improves the installation stability of the cover portion 120, ensures the coverage effect of the cover portion 120 on the first sidewall 101', and guarantees the protective effect of the aforementioned anti-oxidation device 100. Furthermore, the adhesive layer 132 can seal the gap between the cover portion 120 and the aforementioned first sidewall 101', further reducing the risk of the first sidewall 101' contacting air and enhancing the protective effect of the aforementioned anti-oxidation device 100.

[0067] It is understood that the aforementioned adhesive layer 132 can be made of heat-resistant adhesive to improve the temperature resistance of the adhesive layer 132, reduce the risk of failure of the adhesive layer 132 during aluminum electrolysis production, and help ensure the installation stability of the cover plate portion 120. For example, the aforementioned adhesive layer 132 can be made of heat-resistant adhesive with a failure temperature not lower than 1000°C, so that the temperature resistance of the adhesive layer 132 is higher than or equal to 1000°C.

[0068] like Figures 7 to 9 As shown, in some feasible examples, the cover plate portion 120 is a bent plate. One side of the cover plate portion 120 in the bending direction is used to cover at least part of the aforementioned first sidewall 101', and the other part is used to at least partially cover the sidewall of the anode carbon block 100' to be protected that is adjacent to the aforementioned first sidewall 101'. Based on the aforementioned configuration, the cover plate portion 120 can simultaneously cover at least partially the first sidewall 101' of the anode carbon block 100' to be protected and the sidewall adjacent to the aforementioned first sidewall, thereby further preventing the loss of covering material from the sidewall adjacent to the aforementioned first sidewall 101'. This is beneficial to increasing the coverage area of ​​the cover plate portion 120 on the anode carbon block 100' to be protected and further improving the protective effect of the aforementioned anti-oxidation device 100.

[0069] It is understood that the aforementioned sidewall adjacent to the first sidewall 101' can be the side of the anode carbon block 100' to be protected facing other anode carbon blocks when it is placed in the electrolytic cell 200', that is, the aforementioned sidewall adjacent to the first sidewall 101' can be the side of the anode carbon block 100' to be protected facing the electrode seam between the anode carbon blocks.

[0070] Understandably, in practical applications, the bend in the cover plate 120 can be arranged to correspond to the structural corner on the side of the anode carbon block 100' to be protected.

[0071] like Figures 10 to 12As shown, a second aspect of the present disclosure provides a manufacturing apparatus 200 for an anti-oxidation device, used to manufacture an anti-oxidation device 100 for an anode carbon block of an aluminum electrolytic cell as described in any of the first aspects above. The manufacturing apparatus 200 includes: a first casting section 210, comprising a connecting rod casting groove 211 and a first support 212. The first support 212 is disposed at the bottom end of the connecting rod casting groove 211, and the connecting rod casting groove 211 and the first support 212 form a first... A heat dissipation channel 2101 and a connecting rod casting groove 211 are used to cast the connecting rod portion 110; a second casting portion 220 includes a cover plate casting groove 221 and a connecting rod clamp 222. The connecting rod clamp 222 is disposed in the cover plate casting groove 221. The cover plate casting groove 221 is used to cast the cover plate portion 120. The connecting rod clamp 222 is used to clamp one end of the connecting rod portion 110 so that the connecting rod portion 110 is suspended above the cover plate casting groove 221 along the depth direction of the cover plate casting groove 221.

[0072] The apparatus 200 for manufacturing an anti-oxidation device provided in this embodiment includes the aforementioned first casting section 210 and the aforementioned second casting section 220. The first casting section 210 includes a connecting rod casting groove 211 and a first support 212 disposed at the bottom of the connecting rod casting groove 211. The connecting rod casting groove 211 is used to cast the aforementioned connecting rod portion 110; that is, the connecting rod casting groove 211 can be used as a casting mold for the aforementioned connecting rod portion 110 and can accommodate the first molten material used for casting the aforementioned connecting rod portion 110. The first support 212 supports the connecting rod casting groove 211 and forms a first heat dissipation channel 2101 with the connecting rod casting groove 211 to facilitate heat dissipation and cooling of the first molten material within the connecting rod casting groove 211, thereby improving the casting efficiency of the aforementioned connecting rod portion 110. The aforementioned second casting section 220 includes a cover plate casting groove 221 and a connecting rod clamp 222. The cover plate casting groove 221 is used to cast the aforementioned cover plate section 120, that is, the aforementioned cover plate casting groove 221 can be used as a casting mold for the aforementioned cover plate section 120, and can accommodate the second molten material used for casting the aforementioned cover plate section 120. The aforementioned connecting rod clamp 222 is disposed on the aforementioned cover plate casting groove 221 and is used to clamp one end of the cast connecting rod section 110, so that the aforementioned connecting rod section 110 is suspended above the cover plate casting groove 221 along the depth direction of the cover plate casting groove 221, and so that... The end of the connecting rod portion 110 that is away from the connecting rod clamp 222 is located in the aforementioned cover plate casting groove 221. Thus, during the casting of the cover plate portion 120, the connecting rod portion 110 can be inserted into the aforementioned second molten material. After the second molten material cools and solidifies into the aforementioned cover plate portion 120, the fixed connection between the connecting rod portion 110 and the cover plate portion 120 can be completed accordingly. This helps to reduce the assembly difficulty of the connecting rod portion 110 and the cover plate portion 120, saves the assembly operation between the connecting rod portion 110 and the cover plate portion 120, and improves the manufacturing efficiency of the aluminum electrolytic cell anode carbon block anti-oxidation device 100.

[0073] It is understandable that, in the case that the cover plate 120 is a bent plate, it can be further bent and shaped using a bending machine after the cover plate 120 is cast.

[0074] like Figure 10 and Figure 12 As shown, in some examples, the connecting rod clamp 222 includes: a support member 2221 disposed in the cover plate casting groove 221; a plurality of limiting rods 2222 disposed in the support member 2221, the limiting rods 2222 extending along a first direction, the plurality of limiting rods 2222 being arranged at intervals along a second direction, and a clamping space being formed between two adjacent limiting rods 2222, the clamping space being used to accommodate one end of the connecting rod portion 110; wherein, the first direction, the second direction and the depth direction of the cover plate casting groove 221 intersect each other.

[0075] In this technical solution, the connecting rod clamp 222 may include the aforementioned support member 2221 and multiple aforementioned limiting rods 2222. Based on the aforementioned configuration, on the one hand, the connecting rod clamp 222 can use two adjacently arranged limiting rods 2222 to clamp one end of the aforementioned connecting rod portion 110, so that the aforementioned connecting rod portion 110 is suspended above the cover plate casting groove 221 along the depth direction of the cover plate casting groove 221, and the end of the connecting rod portion 110 away from the aforementioned connecting rod clamp 222 is located in the aforementioned cover plate casting groove 221. Thus, during the casting of the cover plate portion 120, the connecting rod portion 110 can be inserted into the aforementioned second molten material, and then the second molten material cools... After being formed into the aforementioned cover plate portion 120, the fixed connection between the connecting rod portion 110 and the cover plate portion 120 can be completed accordingly, which helps to reduce the assembly difficulty of the connecting rod portion 110 and the cover plate portion 120. On the other hand, when there are multiple clamping spaces, the relative position of the connecting rod portion 110 and the aforementioned cover plate casting groove 221 in the aforementioned second direction can be changed by snapping the aforementioned connecting rod portion 110 into different clamping spaces, thereby facilitating the adjustment of the installation position of the connecting rod portion 110 on the cover plate portion 120.

[0076] It is understood that the aforementioned first direction, the aforementioned second direction, and the aforementioned third direction can be perpendicular to each other. For example, the aforementioned first direction is consistent with the width direction of the aforementioned cover plate casting groove 221, and the aforementioned second direction is consistent with the length direction of the aforementioned cover plate casting groove 221.

[0077] For example, the number of the aforementioned limiting rods 2222 is greater than or equal to 3. For instance, the number of the aforementioned limiting rods 2222 can be, but is not limited to, 3, 4, 5, or 6, etc.

[0078] In some feasible examples, the aforementioned limiting rod 2222 is adapted to slide with the aforementioned connecting rod portion 110 so that the position of the connecting rod portion 110 in the aforementioned first direction is adjustable; based on this, in the process of manufacturing the aforementioned anti-oxidation device 100, the relative position adjustability between the connecting rod portion 110 and the cover plate casting groove 221 can be further improved, thereby facilitating the adjustment of the installation position of the connecting rod portion 110 on the cover plate portion 120.

[0079] like Figure 10 and Figure 11 As shown, in some examples, the first casting part 210 further includes a first handle 213 disposed in the connecting rod casting groove 211.

[0080] In this technical solution, the first casting part 210 may also include the aforementioned first handle 213; based on the aforementioned configuration, it is convenient for the operator to pour the cast connecting rod part 110 out of the aforementioned connecting rod casting groove 211 after the aforementioned connecting rod part 110 has been cast, thereby improving the ease of use of the first casting part 210.

[0081] like Figure 10 and Figure 12 As shown, in some examples, the second casting section 220 further includes a second handle 223 disposed in the cover plate casting groove 221.

[0082] In this technical solution, the second casting section 220 may also include the aforementioned second handle 223; based on the aforementioned configuration, it is convenient for operators to pour the cast cover section 120 out of the aforementioned cover casting groove 221 after the cover section 120 has been cast, thereby improving the ease of use of the second casting section 220.

[0083] In some feasible examples, the apparatus 200 for manufacturing the anti-oxidation device may further include a removal tool for removing the connecting rod portion 110 from the connecting rod casting groove 211 and / or for removing the cover plate portion 120 from the cover plate casting groove 221. Exemplarily, the removal tool may include, but is not limited to, a pry bar and a flat chisel.

[0084] In some feasible examples, the second casting section 220 may also include a second support, which is disposed at the bottom end of the cover plate casting groove 221, and the cover plate casting groove 221 and the second support form a second heat dissipation channel.
