[0002] Aluminum electrolytic cells are the main equipment in aluminum industry production. When electrolytic cells are in operation for a long time, the upper structure of aluminum electrolytic cells, such as the anode busbar, is prone to damage, so maintenance and replacement are required.

After maintenance, the hinged supports need to be lifted and installed and fixed to the cell shell. Due to the excessive weight of the hinged supports, the entire installation process is labor-intensive, inefficient, and may even result in hand injuries due to improper manual operation.

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0024] Please refer to Figure 1 As shown, the first aspect of this application proposes an installation structure 1 for an aluminum electrolytic cell, which can assist in the alignment and installation of the hinge support 20 and the cell shell 10 when installing the hinge support 20, making the operation convenient and effectively improving the assembly efficiency.

[0025] The mounting structure 1 includes a slot shell 10, a bearing base 30, a hinged support 20, and a fastener 40. The slot shell 10 includes a connecting portion 11. The hinged support 20 includes a first part 21 and a second part 22. The first part 21 is connected to the connecting portion 11 along a first direction, and the second part 22 is connected to the side of the first part 21 away from the connecting portion 11 in the first direction. The bearing base 30 is detachably connected to the second part 22. The fastener 40 includes a main body 411, a first segment 412 and a second segment 413 connected to the main body 411 on the same side. The first segment 412 and the second segment 413 are arranged opposite to each other in the first direction. In the first direction, the first segment 412 abuts against the surface of the connecting portion 11 away from the first part 21, and the second segment 413 abuts against the surface of the first part 21 away from the connecting portion 11. The surface of the main body 411 is in contact with the surfaces of the first part 21 and the connecting portion 11, respectively.

[0026] The following combination Figures 1 to 4 The specific structure of installation structure 1 will be described in detail.

[0027] like Figure 1 and Figure 2 As shown, the mounting structure 1 includes a groove shell 10, a bearing base 30, a hinged support 20, and a fastener 40.

[0028] like Figure 1 As shown, the tank shell 10 is a structural component used to connect the upper structure (such as the anode busbar, anode guide rod, etc.) of the aluminum electrolysis cell (not shown in the figure) and other components in the mounting structure 1 (such as the hinged support 20 and other components described below). The tank shell 10 has good corrosion resistance and rigidity, which can meet the requirements of long-term stable operation of the aluminum electrolysis cell.

[0029] like Figure 1 As shown, the hinged support 20 serves as a structural component in the mounting structure 1 that supports the aforementioned slotted shell 10. The hinged support 20 possesses good rigidity and strength. The specific features and structure of the hinged support 20 will be described in detail below.

[0030] The first part 21 of the hinge support 20 is connected to the connecting part 11 of the slotted shell 10 along a first direction. It is easy to understand that the slotted shell 10 is disposed above the hinge support 20 along the first direction, which may be the direction of gravity.

[0031] like Figure 1 As shown, the support base 30 serves as a carrier for other components in the installation structure 1, such as the slot shell 10 and the hinged support 20. The support base 30 has good rigidity and strength, and it is not easily damaged by external forces (such as bending deformation or breakage). The specific shape of the support base 30 is not limited here, and designers can design it reasonably according to actual needs. For example, the support base 30 can be a plate structure, a frame structure, or a box structure.

[0032] Understandably, when the upper structure of the electrolytic cell needs to be replaced or repaired, the hinge support 20 and the cell shell 10 are disassembled and separated, and the cell shell 10 is disassembled and separated from the bearing base 30. The cell shell 10 is lifted together with the upper structure of the cell. After the repair is completed, on the one hand, due to the large weight of the hinge support 20, a very large supporting force is required to support the hinge support 20 during installation and then fix it in place. The whole process is labor-intensive and inefficient. On the other hand, the entire installation process takes place in the working environment of the aluminum electrolytic cell, that is, the aluminum electrolytic cell generates a large amount of current when it is working, which makes the magnetic field near the cross-cell busbar relatively strong. During installation, the hinge support 20 is easy to be attracted to the cell shell 10. If the operator does not cooperate properly during installation, it is very easy to squeeze and injure their hands. Figures 1-3As shown, to solve this problem, the installation structure 1 is designed to also include a fastener 40, which is used to reduce the labor intensity of operators and improve installation efficiency. The specific form of the fastener 40 will be described in detail below.

[0033] The fastener 40 includes a main body 411 and a first segment 412 and a second segment 413 connected to the main body 411 on the same side. The first segment 412 and the second segment 413 are arranged opposite to each other in a first direction. It is easy to understand that the first segment 412 and the second segment 413 are arranged opposite to each other, that is, there is a gap between the first segment 412 and the second segment 413. When installing the hinge support 20, the hinge support 20 is lifted, and only the first part 21 and the connecting part 11 of the hinge support 20 need to be snapped between the first segment 412 and the second segment 413. No special force is required for support, which is convenient for workers to operate and has high work efficiency.

[0034] In the first direction, the first segment 412 abuts against the surface of the connecting portion 11 away from the first part 21, and the second segment 413 abuts against the surface of the first part 21 away from the connecting portion 11. The surface of the main body 411 is in contact with the surfaces of the first part 21 and the connecting portion 11, respectively. It can be understood that the first segment 412 and the surface of the connecting portion 11, the second segment 413 and the first part 21, and the surface of the main body 411 and the surfaces of the first part 21 and the connecting portion 11, respectively, are all in surface contact. This results in greater friction between the first segment 412 and the surface of the connecting portion 11, the second segment 413 and the first part 21, and the surface of the main body 411 and the surfaces of the first part 21 and the connecting portion 11, respectively. Consequently, the relative position between the hinge support 20 and the connecting portion 11 is more stable.

[0035] Based on the installation structure 1 of this application embodiment, a fastener 40 is designed, and the surface of the fastener 40 abuts against the surfaces of the connecting part 11 and the hinge support 20. The fastener can achieve relative position stability between the hinge support and the connecting part, which facilitates subsequent installation and fixing of the hinge support and the connecting part by the operators, thereby effectively improving installation efficiency while reducing labor intensity.

[0036] To ensure that when the first segment 412 abuts against the surface of the connecting portion 11 and the second segment 413 abuts against the surface of the first portion 21, the relative position between the first segment 412 and the second segment 413 can be fixed, in some embodiments, such as Figures 1-3As shown, the main body 411 includes a vertical rod 4111 and a handle 4112. The vertical rod 4111 is connected to the first segment 412 and the second segment 413 respectively. The handle 4112 is located on the side of the vertical rod 4111 away from the first segment 412 and the second segment 413, and extends along a second direction at an angle to the first direction. With this design, the vertical rod 4111 is fixedly connected to the first segment 412 and the second segment 413 respectively, forming a U-shape. When installing the hinge support 20, the operator holds the handle 4112 and inserts the U-shaped structure along the second direction onto the periphery of the connecting part 11 and the first part 21, so that the first segment 412 and the second segment 413 can fix the relative position between the first part 21 and the connecting part 11, thereby preventing the hinge support 20 from dropping due to its own weight and affecting the installation process. It should be noted that the second direction forms an angle with the first direction, that is, the second direction includes at least a first component perpendicular to the first direction.

[0037] Furthermore, considering that the first segment 412 and the second segment 413 can fix the relative position between the first part 21 and the connecting part 11, there can be many ways to connect the main body 411 with the first segment 412 and the second segment 413, and these methods can be, but are not limited to, the following embodiments.

[0038] like Figure 3 As shown, for example, in a first embodiment, the main body 411 is integrally formed with the first segment 412 and the second segment 413. The main body 411 can be, but is not limited to, forming an integral structure with the first segment 412 and the second segment 413 through injection molding, welding, or 3D printing. In this design, by designing the main body 411 as an integrally formed structure with the first segment 412 and the second segment 413, the processing difficulty between the main body 411 and the first segment 412 and the second segment 413 can be reduced, and the connection stability between the main body 411 and the first segment 412 and the second segment 413 can be enhanced, making the connecting part 11 and the first part 21 more stably positioned between the first segment 412 and the second segment 413.

[0039] Of course, in the second embodiment, the main body 411 is detachably connected to the first segment 412 and the second segment 413 (not shown in the figure), and the first segment 412 and the second segment 413 can move relative to the main body 411 along the first direction to abut against the surfaces of the connecting part 11 and the first part 21. In this design, along the aforementioned first direction, by adjusting with external force, the first segment 412 and the second segment 413 are brought closer to each other until the first segment 412 abuts against the surface of the connecting part 11 and the second segment 413 abuts against the surface of the first part 21. At this time, the fastener 40 can provide a pre-tightening force to keep the connecting part 11 and the first part 21 in a fixed relative position, thereby preventing the first part 21 from falling along the first direction due to its own gravity. It is worth mentioning that by setting the relatively movable first segment 412 and the second segment 413, the application range of the fastener 40 can be further expanded.

[0040] Furthermore, such as Figure 5 As shown, in some embodiments, there are multiple fasteners 40. It is understood that due to the large overall weight of the slot shell 10 and its upper structure, multiple mounting structures 1 are needed to provide support. Installing multiple mounting structures 1 involves a complex workload, resulting in high labor intensity and low installation efficiency for workers. Therefore, fasteners 40 are needed to assist in the installation process. The specific number of fasteners 40 is not limited here; designers can design them reasonably according to actual needs. For example, when there are two fasteners 40, they are arranged opposite each other about the slot shell 10. It is worth mentioning that, to further enhance the stability of the connection between the connecting part 11 and the hinge support 20, multiple fasteners 40 can also be designed in each mounting structure 1 for reinforcement. In this design, by setting multiple fasteners 40, the connection between the connecting part 11 and the hinge support 20 becomes more stable, preventing individual fasteners 40 from breaking due to long-term use and the hinge support 20 from falling and injuring workers during installation.

[0041] Multiple fasteners 40 are spaced apart in the second part 22. It is worth mentioning that, to facilitate the storage of the fasteners 40, the aluminum electrolysis cell mounting structure 1 also includes a storage component 70, such as... Figures 4-5The storage component 70 shown includes a first rotating part 71 and a second rotating part 72. The first rotating part 71 is fixedly connected to the fixing member 40. One end of the second rotating part 72 is coaxially arranged with the first rotating part 71 to achieve relative rotation. The other end of the second rotating part 72 is fixedly connected to the hinge support 20. When the hinge support 20 needs to be installed, by turning the first rotating part 71, the first rotating part 71 drives the fixing member 40 to rotate along a first preset trajectory, thereby stabilizing the relative position between the hinge support 20 and the connecting part 11. When the fixing member 40 needs to be stored, by turning the first rotating part 71, the first rotating part 71 drives the fixing member 40 to rotate along a second preset trajectory, thereby storing the fixing member 40 in the second part 22. The first preset trajectory and the second preset trajectory are opposite.

[0042] Considering that the installation of fastener 40 is affected by magnetic fields, thus affecting installation efficiency, such as Figures 1-3 As shown, in some embodiments, the tank shell 10 is used to install electromagnetic components capable of generating a magnetic field, and the fixing member 40 is a metal fixing member 40 containing non-ferrous elements. It is easy to understand that the electrochemical reaction in the aluminum electrolysis cell typically generates a huge current. The current path to the aforementioned electromagnetic components results in a strong magnetic field around the tank shell 10. During installation, the fixing member 40 is subjected to magnetic field attraction or repulsion, causing inconvenience in assembly and disassembly. Here, the material of the fixing member 40 is not limited; for example, the fixing member 40 can be made of, but is not limited to, aluminum, stainless steel, etc. In this design, by designing the fixing member 40 to be made of a non-ferrous metal, the fixing member 40 possesses properties such as light weight, high rigidity, and immunity to magnetic field influence, thus facilitating assembly and disassembly.

[0043] like Figure 3 As shown, considering the huge current generated by the electrochemical reaction in the aluminum electrolysis cell, the current will pass through the cell shell 10 to the ground, thus posing a safety hazard. Therefore, an insulating structure needs to be set between the cell shell 10 and the ground to prevent the cell shell 10 from being grounded. In this embodiment, at least a portion of the hinge support 20 is provided to prevent the cell shell 10 from being grounded. Based on this, in this embodiment, the hinge support 20 and the cell shell 10 are separately provided so that an insulating structure can be machined on the hinge support 20.

[0044] Optionally, the first part 21 is an insulating support with insulation properties, and the second part 22 is a rigid support. The first part 21 is integrally formed with the second part 22. The first part 21 being integrally formed with the second part 22 means that the first part 21 can be, but is not limited to, forming a single structure with the second part 22 through injection molding, welding, or 3D printing. It is worth noting that the second part 22 includes a first rigid support 221 and a second rigid support 222. The first rigid support 221 is wide and flat, increasing the support area and allowing the hinge support 20 to better perform its load-bearing function. The second rigid support 222 is narrow, facilitating the insertion of the first pin 60 for fixation when the hinge support 20 is installed on the support base 30. In this design, by using insulating material at the contact point between the hinge support 20 and the connecting part 11, it can limit the current. Furthermore, due to the high magnetic field strength around the housing 10, it can reduce magnetic interference during the installation of the hinge support 20, thus reducing installation inconvenience.

[0045] like Figures 1-4 As shown, in some embodiments, the first direction is the direction of gravity, and the support base 30 is used to support the mounting surface, which can be the ground or the surface of other structures. The hinge support 20 rests on the support base 30, and the connecting part 11 rests on the hinge support 20. It is understood that the connecting part 11 and the hinge have a downward tendency along their own gravity direction due to their own gravity factors. In this design, along the direction of gravity, by designing the connecting part 11 to rest on the hinge support 20 and the hinge support 20 to rest on the support base 30, the various components are fixedly connected and in a stable state, so that the entire mounting structure 1 has good installation stability, and thus can play a better load-bearing role.

[0046] Furthermore, based on the sequential support of the connecting part 11, the hinged support 20, and the bearing base 30, and considering the stability between the aforementioned components, the design is as follows: Figures 3 to 5As shown, in some embodiments, the connecting part 11 and the first part 21 are coaxially provided with a threaded hole 11a extending in a first direction. A bolt 50 is provided in the threaded hole 11a. The connecting part 11 and the first part 21 are connected by the bolt 50, and an insulating sleeve is provided around the bolt 50 to insulate the connection between the bolt 50 and the first part 21. The bearing base 30 is pin-connected to the second part 22. Since some current will pass through the tank shell 10 when the aluminum electrolysis cell is working, and the tank shell 10 itself is conductive, the insulating sleeve is provided around the bolt 50 to insulate the connecting part 11 and the bolt 50, thereby indirectly insulating the connecting part 11 and the hinge support 20. In this design, by designing the first part 21 of the hinge support 20 and the connecting part 11 to be threadedly connected, and the bearing base 30 and the second part 22 of the hinge support 20 to be pin-connected, the entire mounting structure 1 is indirectly fixedly connected.

[0047] It is worth mentioning that when the support base 30 is pinned to the second part 22, the second part 22 and the support base are coaxially provided with a mounting hole 22a extending along the second direction. At this time, the pin can pass through the mounting hole 22a along the second direction to achieve a fixed connection between the support base 30 and the second part 22. Of course, in some other embodiments, at least one of the second part 22 of the hinge support 20 and the support base 30 is provided with a first insert (not shown in the figure), and at least the other of the second part 22 of the hinge support 20 and the support base 30 has a first slot (not shown in the figure). The first insert is inserted into the first slot, thereby achieving a fixed connection between the second part 22 and the support base 30. The above two connection methods achieve a fixed connection between the support base 30 and the second part 22, while facilitating subsequent installation and disassembly between the hinge support 20 and the support base 30.

[0048] The second aspect of this application discloses an aluminum electrolytic cell, including a mounting structure 1. In this design, the aluminum electrolytic cell with the aforementioned mounting structure 1 allows the hinged support 20 to maintain a stable relative position with the connecting part 11 before being fixedly connected, improving the assembly efficiency of the entire mounting structure 1 and thus making the aluminum electrolytic cell as a whole have good ease of installation.
