Description

Technical Field

[0001] The utility model relates to the field of electrolytic aluminum anode guide rods, in particular to an anode guide rod group with enhanced conductivity. Background Art

[0002] In modern industrial production, especially in the field of aluminum electrolysis, the anode guide rod group is a key component for current conduction. The quality of its conductive performance directly affects production efficiency, energy consumption and product quality. In the prior art, the anode part is mainly composed of the anode guide rod, the anode steel claw and the carbon block. The anode voltage drop energy consumption is very large. Further enhancing the conductive performance of the anode carbon block is an effective way to reduce the energy consumption of aluminum electrolysis.

[0003] At present, a Chinese invention patent application with publication number CN110079830A and publication date August 2, 2019 proposes an anode claw for electrolytic aluminum, including: the anode claw for electrolytic aluminum includes a claw head and a guide rod for connecting the claw head to lift the claw head, the guide rod is welded and fixed to the claw head, the claw head is provided with a claw head welding surface welded and fixed to the guide rod, the guide rod is provided with a guide rod welding surface welded and fixed to the claw head, the claw head welding surface and the guide rod welding surface are made of the same material, and the same material is used at the welding position of the claw head and the guide rod to improve the connection strength between the guide rod and the claw head, which is conducive to increasing the conductivity of the welding surface.

[0004] With regard to the above-mentioned related technologies, the anode steel claw guide rod and the anode steel claw are connected by welding. The same material is used only on the welding surface, and the inner core of the gripper is aluminum. After long-term use, due to the higher contact rate between the steel claw and the electrolyte, when the outer steel layer of the steel claw is melted through, it is very easy to cause a high voltage drop, increased contact resistance, and increased electrical loss. Utility Model Content

[0005] In order to improve the conductive effect of electrolytic aluminum anodes, the utility model provides an anode guide rod group with enhanced conductivity.

[0006] The utility model provides an anode guide rod assembly with enhanced conductivity, which adopts the following technical solutions:

[0007] An anode guide rod group with enhanced conductivity includes a guide rod, a steel claw, a conductive core and a connecting mechanism for connecting the guide rod and the steel claw, wherein the steel claw is arranged on the guide rod, the conductive core is arranged inside the guide rod, the conductive core is plugged into the steel claw, one end of the connecting mechanism is arranged on the upper end of the steel claw, and the other end of the connecting mechanism is arranged on the guide rod.

[0008] By adopting the above technical solution, during the aluminum electrolysis process, the guide rod is energized, and then the conductivity between the guide rod and the steel claw is improved under the action of the conductive core, so that the contact resistance is reduced, thereby reducing the electrical loss and saving the electrical energy loss during the aluminum electrolysis process.

[0009] Optionally, the connection mechanism comprises an expansion block, the expansion block is arranged in the guide rod, and one end of the expansion block abuts against the conductive core.

[0010] By adopting the above technical solution, during the electrolytic aluminum process, due to the high temperature of the electrolytic cell, the guide rod and the conductive core will expand to varying degrees after being heated. Since the guide rod and the conductive core are made of different materials, the heat elongation between the guide rod and the conductive core will also be different. Through the expansion block, the expansion elongation after heating is greater than that of the guide rod and the conductive core, thereby pushing the other end of the conductive core to abut against the steel claw, thereby reducing the possibility of the conductive core being out of the conductive position and reducing the impact on the conductivity between the guide rod and the conductive core.

[0011] Optionally, the connecting mechanism further comprises a mounting plate and a connecting plate, wherein the mounting plate is arranged on the steel claw, the connecting plate is slidably arranged on the guide rod, and the mounting plate is fixedly connected to the connecting plate.

[0012] By adopting the above technical solution, during the process of electrolytic aluminum, the steel claws and the guide rods are supported by the mounting plate and the connecting plate, thereby reducing the possibility of deformation of the steel claws and the guide rods after being heated, so that the carbon blocks fixed on the steel claws can be in more balanced contact with the electrolytic cell liquid, thereby reducing the impact on the electrolysis efficiency.

[0013] Optionally, the connection mechanism further includes a protective layer, a filling groove is provided on the connection plate, the protective layer is arranged in the filling groove of the connection plate, and one end of the protective layer abuts against the guide rod.

[0014] By adopting the above technical scheme, during the process of electrolytic aluminum, the connection between the guide rod and the steel claw is susceptible to corrosion, which may damage the guide rod. The guide rod is protected by the mounting plate and the connecting plate, and at the same time, the guide rod is protected by a protective layer. The protective layer may be aluminum oxide, which reduces the possibility of corrosion of the aluminum guide rod. The protective layer can provide a buffer during the electrolysis process, reduce the loss rate of the guide rod, and thereby reduce the possibility of a decrease in the conductivity of the guide rod.

[0015] Optionally, the connecting mechanism further comprises a connecting piece, wherein the connecting piece is arranged on the guide rod and connected to the conductive core.

[0016] By adopting the above technical solution, during the electrolytic aluminum process, the conductive wire that is in contact with the guide rod and is energized is in contact with the connecting piece, so that electricity can directly flow to the conductive core, further improving the conductivity.

[0017] Optionally, a conductive plate is further provided on the guide rod, the conductive plate is provided on the guide rod, and the conductive plate is connected to the conductive core.

[0018] By adopting the above technical solution, during the electrolytic aluminum process, the contact area between the conductive plate and the steel claw is larger, so that the current entering the steel claw can be distributed more evenly, and each gripper on the steel claw can distribute an equal amount of current, while the conductivity can be improved.

[0019] Optionally, the steel claw is also provided with an installation mechanism, which includes a installation tube, an installation ring and a fixing ring. The installation tube is arranged on the steel claw, a installation groove is opened on the steel claw, the installation ring is arranged on the installation tube, the installation ring is arranged in the installation groove, and the fixing ring is arranged on the installation tube.

[0020] By adopting the above technical solution, the mounting tube is formed by casting, so that the anode carbon block and the steel claw can be fixedly connected. By arranging a mounting ring on the mounting tube, the connection between the mounting tube and the steel claw is made more stable. A fixing ring is arranged on the mounting tube, so that the mounting tube can be in contact with the anode carbon block more firmly, reducing the possibility of loosening, thereby making the current guided by the steel claw to the anode carbon block more stable.

[0021] Optionally, the mounting mechanism further includes a disassembly ring, and the disassembly ring is arranged on the mounting tube.

[0022] By adopting the above technical solution, when the anode needs to be replaced, after the anode carbon block is removed, the installation pipe can be easily removed from the steel claw by breaking the disassembly ring, which reduces the difficulty of disassembling the flow installation pipe and is conducive to casting molding.

[0023] In summary, the present invention includes at least one of the following beneficial technical effects:

[0024] By providing a conductive core, the conductivity between the guide rod and the steel claw is improved under the action of the conductive core, so that the contact resistance is reduced, thereby reducing the electrical loss and saving the electrical energy loss in the electrolytic aluminum process.

[0025] By providing the expansion block, the possibility of the conductive core being separated from the conductive position is reduced, and the influence on the conductivity between the guide rod and the conductive core is reduced.

[0026] By providing a protective layer, which may be aluminum oxide, the possibility of corrosion of the aluminum guide rod is reduced. During the electrolysis process, the protective layer can provide a buffer, reduce the loss rate of the guide rod, and further reduce the possibility of a reduction in the conductivity of the guide rod.

DETAILED DESCRIPTION

[0031] The following combination Figures 1 to 3 The utility model is described in further detail.

[0032] The utility model embodiment discloses an anode guide rod assembly with enhanced conductivity. Figures 1 to 3 A conductive anode guide rod group with enhanced conductivity mainly includes a guide rod 100, a steel claw 200, a conductive core 300, a conductive plate 400, a connecting mechanism 500 and a mounting mechanism 600. One end of the steel claw 200 is installed on the guide rod 100 through the connecting mechanism 500. The conductive core 300 is inserted through the guide rod 100 and the steel claw 200. The conductive plate 400 is installed on the guide rod 100. The conductive plate 400 is connected to the conductive core 300. The mounting mechanism 600 is installed on the steel claw 200. Under the action of the conductive core 300, the conductivity between the guide rod 100 and the steel claw 200 is improved.

[0033] Reference Figure 1 and Figure 2 The connecting mechanism 500 includes a mounting plate 510, an expansion block 520, a connecting plate 530, a protective layer 540 and a connecting piece 550. The mounting plate 510 is fixedly mounted on the steel claw 200 by bolts. The connecting plate 530 is slidably arranged on the guide rod 100. The expansion block 520 is fixedly mounted in the guide rod 100 by snapping. One end of the expansion block 520 abuts against the conductive core 300. The mounting plate 510 and the connecting plate 530 are fixedly connected by bolts. A filling groove 560 is provided on the connecting plate 530. The protective layer 540 is filled in the filling groove 560 of the connecting plate 530. The protective layer 540 is aluminum oxide. One end of the protective layer 540 abuts against the guide rod 100. The connecting piece 550 is arranged on the guide rod 100, and the connecting piece 550 is connected to the conductive core 300.

[0034] During the electrolysis of aluminum, the steel claw 200 and the guide rod 100 are supported by the mounting plate 510 and the connecting plate 530, which reduces the possibility of deformation of the steel claw 200 and the guide rod 100 after being heated, so that the carbon block fixed on the steel claw 200 can be in more balanced contact with the electrolytic cell liquid, reducing the impact on the electrolysis efficiency. During the electrolysis process, the protective layer 540 can provide a buffer, reducing the loss rate of the guide rod 100, and thus reducing the possibility of a decrease in the conductivity of the guide rod 100. Due to the high temperature of the electrolytic cell, the guide rod 100 is After being heated, the rod 100 and the conductive core 300 will both expand to varying degrees. Since the guide rod 100 and the conductive core 300 are made of different materials, the amount of elongation caused by heating between the guide rod 100 and the conductive core 300 will also be different. Through the expansion block 520, the amount of expansion and elongation after being heated is greater than that of the guide rod 100 and the conductive core 300, thereby pushing the other end of the conductive core 300 to abut against the steel claw 200, thereby reducing the possibility of the conductive core 300 being out of the conductive position, and reducing the impact on the conductivity between the guide rod 100 and the conductive core 300.

[0035] During the electrolytic aluminum process, the contact area between the conductive plate 400 and the steel claw 200 is larger, which can make the current entering the steel claw 200 more evenly distributed, so that each gripper on the steel claw 200 can distribute an even amount of current, and at the same time improve the conductivity.

[0036] Reference Figures 1 to 3 The mounting mechanism 600 includes a mounting tube 610, a mounting ring 620, a fixing ring 630 and a disassembly ring 640. The mounting tube 610 is arranged on the steel claw 200. The steel claw 200 is provided with a mounting groove 650. The mounting ring 620 is arranged on the mounting tube 610. The mounting ring 620 is sleeved in the mounting groove 650. The fixing ring 630 is arranged on the mounting tube 610. The disassembly ring 640 is arranged on the mounting tube 610.

[0037] The mounting tube 610 is formed by casting, so that the anode carbon block and the steel claw 200 can be fixedly connected. By arranging a mounting ring on the mounting tube 610, the connection between the mounting tube 610 and the steel claw 200 is more stable. A fixing ring 630 is arranged on the mounting tube 610, so that the mounting tube 610 can be in contact with the anode carbon block more firmly, reducing the possibility of loosening, thereby making the current guided to the anode carbon block by the steel claw 200 more stable. When the anode needs to be replaced, after the anode carbon block is removed, the mounting tube 610 can be easily disassembled from the steel claw 200 by breaking the disassembly ring 640, which reduces the difficulty of disassembling the flow mounting tube 610 and is conducive to casting molding.

[0038] The implementation principle of the anode guide rod group for enhancing electrical conductivity in the embodiment of the utility model is as follows:

[0039] During the aluminum electrolysis process, the guide rod 100 is energized, and then the conductivity between the guide rod 100 and the steel claw 200 is improved under the action of the conductive core 300, so that the contact resistance is reduced, thereby reducing the electrical loss and saving the electrical energy loss during the aluminum electrolysis process.

[0040] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
