[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] like Figure 1 As shown, alumina is the most important material in the electrolytic aluminum process. Common feeding methods include using compressed air to move the material in the feed pipe until it enters the chamber 1. In order to balance the atmospheric pressure during the feeding process, a return air pipe 5 is installed in the chamber 1 to connect the feed box to the electrolytic cell.

[0024] Due to various factors, the material supply air pressure often becomes unstable during the feeding process. When excessive air pressure occurs, the material may be carried into the electrolytic cell 1 through the return air pipe 5 under the action of compressed air.

[0025] like Figure 1 As shown, hollow arrows indicate the material movement trajectory during normal feeding; black arrows indicate the material movement trajectory when material leaks.

[0026] Therefore, the main problems caused by material leakage include:

[0027] Firstly, uneven material thickness in certain areas of the anode shell can cause the anode rod to break when the electrode is replaced due to excessive weight of the residual electrode.

[0028] Secondly, some materials may leak into the electrolyte, disrupting the electrolyte concentration in certain areas and causing a loss of concentration in the electrolytic zone. This leads to uncontrolled alumina concentration in the electrolytic cell, frequent electrolytic effects, and increased resistance. Consequently, the cell temperature rises, current utilization efficiency decreases, and the cell is prone to overheating.

[0029] Thirdly, it leads to material waste. The leaked alumina does not participate in the electrolytic reaction, resulting in increased production costs.

[0030] Fourthly, the insulation material on the anode shell becomes uncontrolled. This, in turn, affects the thermal balance of the electrolytic cell, and changes in the thermal balance can easily lead to anodizing.

[0031] Fifthly, the multi-functional overhead crane's shell-opening head cannot enter. The inability of the overhead crane's shell-opening head to enter affects the quality of the pole-changing operation, which in turn leads to problems such as uneven current distribution.

[0032] Sixthly, the repeated cleaning of leaking material from the anode shell by employees increases their workload. The increased size of the crust leads to a greater workload during electrode replacement, wasting manpower.

[0033] Currently, the main difficulties in solving the leakage problem are: the upper structure of the electrolytic cell tank has a compact layout of equipment and facilities; there is a high magnetic field on site, making it difficult to install large equipment; existing solutions do not completely solve the leakage problem; and a large amount of leakage still needs to be manually cleaned up during the on-site cleanup.

[0034] To address the above issues, existing methods for preventing material leakage have not yielded satisfactory results, such as installing a dust collector at point 5 of the return air duct.

[0035] This application analyzes the main causes of leakage in return air duct 5. The main causes of leakage in return air duct 5 include:

[0036] Reason 1: The air duct of the shell-breaking cylinder is connected to the alumina material box. When the cylinder retracts during shell breaking, the compressed air pressure increases. Since the compressed air is connected to the feed inlet 2 of the electrolytic cell material box, this causes excessive internal pressure in the box 1. The excessively pressurized compressed air flows back into the material box, carrying alumina into the return air duct 5, and finally falls onto the shell surface through the gas collection hood.

[0037] Reason 2: Unstable quality of alumina raw materials. When the quality of alumina changes significantly, the particle size varies greatly, resulting in excessively small alumina particles. Alumina particles that are too small are easily carried into the return air duct 5 by compressed air, causing material leakage.

[0038] Reason 3: Structural issue with return air duct 5. When the gas-material mixture containing alumina passes through return air duct 5, the material falls back into box 1 upon colliding with the inner wall of return air duct 5. However, due to the compact upper structure of the electrolytic cell's material box, and to avoid interference with other equipment, such as... Figure 1 As shown, the return air duct 5 is generally installed at an angle. The angle of inclination of the return air duct 5 is small and the duct is short, which means that most of the material cannot fall completely back into the box 1.

[0039] In this embodiment of the application, considering the cause of material leakage in the return air duct 5, this application designs an electrolytic cell material box with gas-material separation function, which fundamentally solves the material leakage problem.

[0040] like Figure 2 As shown in the figure, this application embodiment provides an electrolytic cell material box with gas-material separation function, which mainly includes: box body 1, inlet 2, outlet 3, gas-material output port 6, gas-material separation device 8, filter component 7, and return pipe 9.

[0041] In this embodiment, the connection relationships between the components of the electrolytic cell tank with gas-material separation function are further described. The tank body 1 is fixedly equipped with an inlet 2 and an outlet 3. An outlet 3 is fixedly equipped with a gas-material output port 6. The gas-material output port 6 is sleeved onto a transfer pipe 7. The transfer pipe 7 is sleeved onto a gas-material separation device 8. A filter component 7 is installed inside the gas-material separation device 8. The gas-material separation device 8 is fixedly connected to a return pipe 9, which connects to the electrolytic cell 4 to prevent gas leakage into the atmosphere.

[0042] Optionally, a filter element 7 can be installed inside the gas-material separation device 8 by providing a window that can be opened and closed. The filter element 7 is used to further filter the gas-material mixture.

[0043] Optionally, filter element 7 can be replaced periodically or irregularly.

[0044] like Figure 2 As shown, arrow a represents the material movement trajectory during normal feeding; arrow b represents the material movement trajectory during leakage; arrow c represents the material movement trajectory after gas-material separation; and arrow d represents the gas movement trajectory after gas-material separation. The gas-material separation device 8 achieves the function of gas-material separation, meaning that gas is discharged into the electrolytic cell 4 through the return pipe 9, while the material enters the interior of the tank 1. Therefore, it solves the problem of material leakage caused by back-blowing of the alumina material box in the electrolytic cell, avoids the labor costs associated with manual recovery due to leakage, and improves the quality of operation.

[0045] In this embodiment of the application, no other energy source is used to address the air leakage problem of the reverse blowing device. The gas-material separation device 8 achieves the gas-material separation function through physical isolation, fundamentally solving the leakage problem caused by reverse blowing.

[0046] like Figure 3 As shown in the figure, this application provides a gas-material separation device 8 for an electrolytic cell tank. The gas-material separation device 8 mainly includes: an installation pipe 8-1, a trapezoidal hopper 8-2, a separation box 8-3, a baffle plate 8-4, a top plate 8-5, a connecting pipe 8-6, and a separated gas outlet pipe 8-7.

[0047] Optionally, the gas-material separation device 8 further includes a window 8-8. By opening and closing the window 8-8, a filter element 7 can be installed inside the gas-material separation device 8. The filter element 7 is used for further filtering the gas-material mixture.

[0048] Optionally, the filter element 7 can be a filter bag. The filter bag has a connecting structure and can be fixed inside the gas separation outlet pipe 8-7. A double-door (an example of window 8-8) is provided at the same height as the filter bag in the gas separation outlet pipe 8-7 for filter bag replacement; the double-door is surrounded by a sealing layer. The purpose of the filter bag is to increase the travel distance of the gas-material mixture, increase the travel angle of the gas-material mixture, and increase the material collision distance. The filter bag, fixed inside the gas separation outlet pipe 8-7, can filter the gas-material mixture inside the gas separation outlet pipe 8-7, further blocking material and further preventing leakage.

[0049] Optionally, the filter element 7 can be a filter bag. The gas separation outlet pipe 8-7 is divided into an upper gas separation outlet pipe and a lower gas separation outlet pipe at the location where the filter bag is placed. The filter bag serves as a connecting structure and is fixed inside the gas separation outlet pipe, meaning the filter bag completely covers the outlet of the upper gas separation outlet pipe. The filter bag is fixedly connected to the upper gas separation outlet pipe and the lower gas separation outlet pipe respectively by adhesive.

[0050] like Figure 3 As shown, the arrows indicate the movement path of the gas-fuel mixture. The length of this path increases due to the action of multiple baffles 8-4. Because of the bending arrangement of the multiple baffles 8-4, the gas-fuel mixture undergoes multiple large-angle turns, entering the space formed by the next baffle 8-4 through narrow gaps. This increases the probability of collisions between the gas-fuel mixture and the sidewalls of the separation chamber 8-3 and the surfaces of the baffles 8-4.

[0051] In other words, the increased movement path length and collision probability of the gas-material mixture increase the likelihood of the material in the gas-material mixture entering the chamber 1 after colliding with the side wall of the separation chamber 8-3 and the surface of the baffle plate 8-4, thereby improving the gas-material separation effect.

[0052] Optionally, multiple baffles 8-4 can be configured, or the number of baffles 8-4 can be increased to further improve the gas-material separation effect.

[0053] Optionally, multiple baffles 8-4 are staggered, with one edge of each baffle 8-4 welded to the inner wall of the separation chamber 8-3. For example, the welded end of the first baffle 8-4, which is inclined, is lower than the end of the second baffle 8-4 in a horizontal position, and the welded end of the second baffle 8-4 is lower than the end of the third baffle 8-4.

[0054] Optionally, the separator 8-3 has a cuboid structure, and the baffle 8-4 is a rectangular plate. Three sides of the rectangular baffle 8-4 are welded to the three sides of the separator 8-3. The unwelded sides of the baffle 8-4, also referred to as the ends, form a narrow gap between the unwelded sides of the baffle 8-4 and the unwelded sides of the separator 8-3. This narrow gap allows the gas-material mixture or separated air to pass through. This narrow gap reduces the flow velocity of the gas-material mixture and increases the probability of collision between the gas-material mixture and the side walls of the separator and the baffle.

[0055] Optionally, the multiple baffles 8-4 are staggered, with one edge of each baffle 8-4 welded to the inner wall of the separation chamber 8-3. For example, ... Figure 4 As shown, from top to bottom, the unwelded end of the first baffle 8-4, which is inclined, is lower than the welded end of the second baffle 8-4 in a horizontal position, and the unwelded end of the second baffle 8-4 is lower than the welded end of the third baffle 8-4.

[0056] Optionally, the angle between the baffle plate 8-4 and the side wall of the separation box 8-3, and the narrow gap between multiple baffle plates 8-4 can be designed according to the flow characteristics of the material to achieve the best gas-material separation effect.

[0057] Optionally, the installation pipe 8-1, trapezoidal hopper 8-2, separation box 8-3, baffle plate 8-4, top plate 8-5, connecting pipe 8-6, and separated gas outlet pipe 8-7 are all made of steel plates coated with anti-corrosion materials.

[0058] Optionally, the gas-material separation device 8 is a single welded component to ensure its airtightness. For example... Figure 4 As shown in the embodiments of this application, the welding process of the gas-material separation device 8 is further explained. Figure 4 The black graphic indicates the welding position.

[0059] like Figure 4 As shown, the upper part of the installation pipe 8-1 is welded to the trapezoidal hopper 8-2, and the lower part of the installation pipe 8-1 can be sleeved to the gas output port 6; the upper end of the trapezoidal hopper 8-2 is welded to the lower port of the separation box 8-3; multiple baffles 8-4 are welded to the inner surface of the side wall of the separation box 8-3; the top plate 8-5 is welded to the upper port of the separation box 8-3; the connecting pipe 8-6 is welded to the outer surface of the side wall of the separation box 8-3; one end of the separated gas outlet pipe 8-7 is welded to the connecting pipe 8-6, and the other end is sleeved to the return tank pipe 9.

[0060] Optionally, in order to make the installation pipe 8-1 fit into the gas outlet 6, the inner diameter of the lower part of the installation pipe 8-1 is equal to the outer diameter of the gas outlet 6; or the outer diameter of the lower part of the installation pipe 8-1 is equal to the inner diameter of the gas outlet 6.

[0061] For example, such as Figure 4 As shown, the inner diameter of the lower end of the mounting pipe 8-1 is set to d1, and its outer diameter is the same as the outer diameter of the gas outlet 6. The outer diameter of the separated gas outlet pipe 8-7 is set to d2, and its outer diameter is the same as the inner diameter of the returned pipe 9. Firstly, this simplifies the installation process of the gas-material separator 8, eliminating unnecessary adapters and reducing costs. Secondly, after the inner diameter circular surface of the lower part of the mounting pipe 8-1 is fitted with the outer diameter circular surface of the gas outlet 6, and after the outer diameter circular surface of the lower part of the separated gas outlet pipe 8-7 is fitted with the inner diameter circular surface of the returned pipe 9, the connection is sealed with sealant and a filter bag, improving the overall sealing performance of the device. Thirdly, this simplifies the installation and disassembly process of the gas-material separator 8, facilitating replacement and maintenance. In other words, there is no welding or screwing fixing between the gas-material separator 8 and the gas outlet 6 and returned pipe 9 of the housing 1, improving the efficiency of installation and disassembly of the gas-material separator 8.

[0062] Optionally, except for the mounting pipe 8-1, all components of the gas-material separation device 8 are fully welded together to ensure the airtightness of the gas-material separation device 8.

[0063] For example, the separation chamber 8-3 is a cuboid box with a length of 250mm, a width of 250mm, and a height of 620mm. The separation chamber 8-3 has four side walls and a top plate 8-5 fully welded to the four side walls. A connecting pipe 8-6 is connected to one of the side walls, positioned 75mm vertically from the top plate 8-5. A separated gas outlet pipe 8-7, with a total length of 855mm, is welded to the other end of the connecting pipe 8-6. A filter element 7, such as a cloth bag, is installed on the upper half of the gas outlet pipe 8-7. These dimensions are the optimal design dimensions obtained after repeated testing.

[0064] For example, three inclined baffles 8-4 are welded inside the separation chamber 8-3. The baffles 8-4 are all 297mm long. The first baffle 8-4 is welded to the side wall away from the connecting pipe 8-6 at the weld point with the top plate 8-5. The angle between the first baffle 8-4 and the top plate 8-5 and the side wall is 45°. The second baffle 8-4 is welded to the side wall of the connecting pipe 8-6 at a distance of 200mm from the top plate 8-5, also at a 45° angle. The third baffle 8-4 is welded to the side wall away from the connecting pipe 8-6 at a distance of 400mm from the top plate 8-5, also at a 45° angle. The 45° angles between the multiple baffles 8-4 and the top plate 8-5 and the side wall are the optimal angles calculated based on the flowability of the existing alumina, maximizing the gas-material separation effect.

[0065] For example, the bottom of the separation chamber 8-3 is fully welded with a trapezoidal hopper 8-2. The upper surface of the trapezoidal hopper 8-2 is a square with a side length of 250mm, the lower surface is a circular surface with a diameter of 88mm, and the height is 60mm. The welding angle between the four walls of the trapezoidal hopper 8-2 and the four walls of the separation chamber 8-3 is 135°. The four side walls of the trapezoidal hopper 8-2 are inclined and fully welded to the four walls of the separation chamber 8-3, with the bottom tapering into a circle. The dimensions and angles involved are the result of multiple tests confirming the structure with the best separation effect.

[0066] For example, the bottom circular surface of the trapezoidal hopper 8-2 is used as the welding surface, and the mounting tube 8-1 is fully welded thereon. The upper diameter of the mounting tube 8-1 is 80mm, the lower diameter is 88mm, and the total length is 100mm. The upper length of the mounting tube 8-1 is 90mm, and the lower length is 10mm. After the upper part of the mounting tube 8-1 extends into the gas-material separator, the upper outer circular surface of the mounting tube 8-1 is fully welded to the bottom circular surface of the trapezoidal hopper 8-2.

[0067] Furthermore, this application provides a gas-material separation device for an electrolytic cell tank. Since simplistic and crude equipment management is a thing of the past, refined management has become an inevitable trend. Addressing leaks and spills is a crucial aspect of refined management. The problem of material leakage from the back-blowing air of the alumina tank in the electrolytic cell must be solved. Frequent leakage leads to repeated cleaning, significantly increasing workload. It also increases the size of the crust, making electrode replacement more difficult. Frequent leakage also causes material accumulation on the electrolytic cell surface, leading to a decline in electrode replacement quality and wasted costs. This application can solve the problem of material leakage from the back-blowing air of the alumina tank in the electrolytic cell.

[0068] In this embodiment, baffles 8-4 are used to physically isolate the gas-material mixture. The gas-material separation device 8 separates the gas and material, fundamentally solving the problem of material leakage from the back-blowing device. Furthermore, it eliminates the need for other energy sources, reducing costs.

[0069] In this embodiment, the problem of increased manual labor caused by the need for manual recovery of leaked materials is avoided.

[0070] In this embodiment, the electrolyte concentration is controlled, the runaway of the anode shell insulation material is avoided, and the quality of the electrolysis operation is improved.

[0071] In this embodiment of the application, taking alumina as an example, when the gas in the electrolytic cell tank carries alumina into the gas-material separation device 8, the baffles 8-4 fully welded in the gas-material separation device 8 will block the alumina. After being blocked by multiple layers of baffles 8-4, the alumina is blocked back to the electrolytic cell tank, while the gas is transferred to the next step through the separated gas outlet pipe 8-7, thereby realizing the physical separation of gas and alumina.

[0072] In this embodiment, to ensure gas-material separation after the gas-material mixture passes through the gas-material separator 8, the entire device must be a sealed space, with sealed edges and sides. The gas-material mixture can only be discharged through one channel. Therefore, during project implementation, all welding parts require full welding. However, to avoid interference with other equipment, the overall size of the gas-material separator 8 is small, preventing the welding torch from entering. Therefore, the welding process of the gas-material separator 8 needs to be broken down. For example, the internal and side structure assembly welding is completed first, followed by overall assembly welding. This is necessary to complete the welding of the baffle plate, thus achieving the goal of extending the gas-material mixture's travel distance. In other words, the gas-material mixture will not leak through the weld at the baffle plate 8-4 welding end, thus failing to achieve the goal of extending the gas-material mixture's travel distance.

[0073] In this embodiment, an installation pipe 8-1 is provided at the bottom. The lower outer diameter d1 of the installation pipe 8-1 is equal to the inner diameter of the gas-material output port 6. It is connected to the material box 1 of the electrolytic cell's material box to avoid welding, thus reducing the amount of welding required. After the lower outer diameter d1 of the installation pipe 8-1 is fitted with the inner diameter of the gas-material output port 6, the connection is secured by a cloth bag tie or sealant filling the joint, ensuring a tight seal. Furthermore, when replacing or maintaining the gas-material separation device 8, only the cloth bag tie or sealant needs to be removed, improving replacement efficiency.

[0074] For example, when the gas-material separation device 8 has been used for a long time, the process of replacing the gas-material separation device 8 with a new one can ensure that there will be no leakage of material or gas by sealing the gas output port 6.
