Description

Technical Field

[0001] This application relates to the field of aluminum electrolysis technology, and in particular to a current regulating device, method and related equipment for a continuous anode in an aluminum electrolysis cell. Background Technology

[0002] Currently, with social development and technological progress, electrolytic cell anodes have evolved from small prebaked anodes to side-inserted self-baking anodes, to top-inserted self-baking anodes, and back to prebaked anodes. Traditional self-baking cells suffer from drawbacks such as uneven current distribution, complex anode operation, harsh environment, high energy consumption, and difficulty in achieving automation, intelligence, and large-scale production. Therefore, prebaked cell technology is mostly used in actual production. Although current prebaked cell technology has made significant progress in terms of large-scale production and automation, it still has obvious shortcomings such as long process and interference with the stability of the electrolytic cell during the electrode switching process. Therefore, further research and development has been carried out to address the shortcomings of traditional self-baking cells and prebaked cells, resulting in the discovery of continuous anode self-baking cells.

In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0035] First, the applicable application scenarios of this application will be introduced. The embodiments provided in this application are applicable to the field of aluminum electrolysis technology.

[0036] Currently, in the process of aluminum electrolysis using continuous anodes, the special current-leading structure results in uneven current density distribution during the operation of the anode, leading to problems such as reduced electrolysis efficiency.

[0037] Based on this, the embodiments of this application provide a current regulation device, method and related equipment for a continuous anode of an aluminum electrolysis cell. The embodiments provided by this application can improve the problem of uneven current density distribution in the continuous anode assembly during electrolysis and improve the electrolysis efficiency of the aluminum electrolysis cell.

[0038] Figure 1 This is a top view of a current regulating device for a continuous anode in an aluminum electrolysis cell, provided in an embodiment of this application. Exemplary, such as... Figure 1 As shown, the current regulating device 1 of the continuous anode of the aluminum electrolysis cell includes: multiple regulating devices 10 and conductive components 20. The conductive components 20 are connected to the regulating devices 10 and connected to the anode components of the aluminum electrolysis cell. The conductive components 20 are located between the regulating devices 10 and the anode components and are used to conduct conductive ionization of the continuous anode of the aluminum electrolysis cell.

[0039] The specific number of the regulating devices 10 in the embodiments provided in this application is determined according to the magnitude of the current load in the aluminum electrolysis cell, and the specific number is not limited.

[0040] In some examples, for aluminum electrolytic cells with large current loads, the embodiments provided in this application may provide at least 6 regulating devices 10; while for electrolytic cells with small current loads, the embodiments provided in this application may provide at least 4 regulating devices 10.

[0041] It should be noted that current load refers to the amount of current consumed during operation, usually expressed in amperes (A), which indicate the strength of the current. The magnitude of the current load is closely related to the power during operation; the greater the power, the greater the current.

[0042] In some examples, at least two regulating devices 10 are grouped together. At least two regulating devices 10 in a group are respectively disposed on opposite sides of the anode assembly. The regulating devices 10 in the same group apply pressure to or release pressure to the anode assembly through the conductive component 20 to adjust the current density of the anode assembly. The at least two regulating devices 10 in the same group can have the same structure, and the regulating devices 10 in different groups can also have the same structure.

[0043] The regulating device 10 in the embodiments provided in this application is used to regulate the pressure between the conductive component 20 and the anode component. The principle of grouping at least two regulating devices 10 together and setting at least two regulating devices 10 in a group on opposite sides of the anode component is to regulate the current density of the anode component in a zone during electrolysis. In this application, the conductive component 20 and the regulating device 10 are connected by a transmission. When uneven current density distribution is detected in the continuous anode of the aluminum electrolysis cell, the regulating device 10 presses or loosens the conductive component 20 to change the pressure between the conductive component 20 and the anode component, thereby changing the resistance between the conductive component 20 and the anode component. Since the voltage is a fixed externally applied voltage value, according to Ohm's law, if the resistance between the conductive component 20 and the anode component changes when the voltage is constant, the current density distribution between the conductive component 20 and the anode component will also change. This improves the problem of uneven current density distribution in the continuous anode component during electrolysis and increases the electrolysis efficiency of the aluminum electrolysis cell.

[0044] It should be noted that when the pressure between the conductive component 20 and the anode component is increased, the resistance between them decreases, resulting in a larger current density distribution. This enhances the current density distribution between the conductive component 20 and the anode component. Conversely, when the pressure between the conductive component 20 and the anode component is decreased, the resistance between them increases, resulting in a smaller current density distribution. This reduces the current density distribution between the conductive component 20 and the anode component.

[0045] It should be noted that the adjustment device 10 in the embodiments provided in this application is specifically set to 4 or 6, and the 4 or 6 adjustment devices 10 are set to a group of two, and the two in each group are respectively set on opposite sides of the anode assembly (on the two opposite sides) to adjust the current density distribution of the anode assembly.

[0046] The electrolytic cell provided in this application consists of a cell body, an anode, and a cathode. Most of them use a diaphragm to separate the anode chamber and the cathode chamber. Electrolytic cells can be divided into three categories according to the different electrolytes: aqueous solution electrolytic cells, molten salt electrolytic cells, and non-aqueous solution electrolytic cells. When direct current passes through the electrolytic cell, an oxidation reaction occurs at the interface between the anode and the solution, and a reduction reaction occurs at the interface between the cathode and the solution to produce the desired product.

[0047] It should be noted that current density is a physical quantity used to describe the strength and direction of current at a point in a circuit. Its magnitude is equal to the amount of charge passing through a unit area per unit time, and its direction vector is the normal vector of the corresponding cross section of the unit area. The direction of its direction vector is determined by the direction in which the positive charge passes through this cross section.

[0048] In some examples, the conductive component 20 includes multiple conductive rods 201, an internal conductor group 202, and a conductive frame 203. Multiple conductors of the internal conductor group 202 are embedded inside the anode component. The conductive frame 203 is fixedly mounted on the outer wall of the anode component. The conductive rods 201 are connected to the outside of the conductive frame 203. One end of the conductive rod 201 is connected to the conductive frame 203, and the other end of the conductive rod 201 is attached to the adjustment device 10. The number of conductive rods 201 is the same as the number of adjustment devices 10, and they correspond one-to-one.

[0049] In the embodiments provided in this application, multiple conductors within the built-in conductor group 202 are equally spaced and embedded inside the anode assembly, and the spacing between any two conductors can be, but is not limited to, 15-20 cm; in the embodiments provided in this application, conductive rods 201 are evenly distributed on the outside of the conductive frame 203, one side of which is pressed against the conductive frame 203, and the other side is attached to the adjustment device 10, and the number of conductive rods 201 is consistent with the number of adjustment devices 10; in the embodiments provided in this application, the conductive frame 203 is located around the outer wall of the anode assembly, closely attached to the anode assembly, and the embodiments provided in this application... In the example, the conductive frame 203 is discontinuous. Specifically, the discontinuity can be achieved by providing multiple openings on the conductive frame 203 and providing an insulating component 40 at each opening. That is, the insulating component 40 is tightly connected to the conductive frame 203 at the opening. In the embodiment provided in this application, the insulating component 40 is also evenly distributed on the outside of the anode component. Specifically, it can be set on opposite sides of the outside of the anode component. The insulating component 40 and the conductor are spaced apart, so that any two adjacent insulating components 40 can divide the anode component into several parts, that is, multiple anode partitions, which facilitates the control of current density distribution.

[0050] In the embodiments provided in this application, each anode partition is a relatively independent area, which facilitates the sensor in the sensing component to detect the current density. In the embodiments provided in this application, the position of the insulating component 40 and the conductor cannot be on the same straight line, and the number of insulating components 40 is two fewer than the number of adjusting devices 10.

[0051] In some examples, the regulating device 10 includes a sensing assembly with multiple sensors electrically connected to conductors, where the conductors space the anode assembly to form multiple anode partitions, and the sensors are used to detect the current density of the anode partitions.

[0052] It should be noted that the sensor in the embodiments provided in this application is electrically connected to the conductor and is used to detect the current density of the anode zone in real time.

[0053] In some examples, the current regulating device 1 of the continuous anode of the aluminum electrolysis cell further includes: a support component 30, which is installed on the outer wall of the anode group and at a preset distance from the anode group. The regulating devices 10 are all fixedly installed on the support component 30, which is used to support the regulating devices 10.

[0054] It should be noted that the support component 30 is installed around the outer wall of the anode group and at a distance of 20-50cm from the anode group. More than four adjustment devices 10 are installed at different positions on the support component 30. In the embodiment provided in this application, the support component 30 is used to support each adjustment device 10 so that the adjustment device 10 can more accurately and stably determine the current density distribution adjustment of the anode group in the aluminum electrolysis cell.

[0055] It should be noted that the support component 30 in the embodiments provided in this application may be specifically, but is not limited to, a support frame.

[0056] In some examples, to improve the adjustment accuracy of the current density of the anode assembly, the number of adjustment devices 10 can be determined to be six. In this case, the six adjustment devices 10 are arranged in pairs on opposite sides of the support frame, and the six adjustment devices 10 are equally spaced on opposite sides of the anode assembly, respectively located on the upper left side (e.g., Figure 1 (position 10a) and the middle of the upper side (e.g.) Figure 1 (position 10b), upper right side (e.g.) Figure 1 (10c position in the middle) and lower left side (such as...) Figure 1 (middle 10d position), lower middle (e.g.) Figure 1 (10e position in the middle) and the lower right side (such as Figure 1 For ease of distinction, the adjustment devices 10 at the above six positions are respectively labeled as 10a (upper left), 10b (upper middle), 10d (upper right), 10c (lower left), 10e (lower middle), and 10f (lower right). The setting of the adjustment device 10 will not affect the normal operation of other equipment components in the continuous anode electrolysis cell.

[0057] Figure 2 This is a side view of the regulating device in a current regulating apparatus for a continuous anode in an aluminum electrolysis cell, as provided in an embodiment of this application. For example,... Figure 2 As shown, the adjustment device 10 includes a power component 101, a reduction component 102, a telescopic rod 103, and a contact pad 104. The drive output end of the power component 101 is connected to the input end of the reduction component 102. The output end of the reduction component 102 is connected to one end of the telescopic rod 103. The other end of the telescopic rod 103 is connected to the contact pad 104. The contact pad 104 is in contact with the other end of the conductive rod 201. The adjustment device 10 also includes a connecting component 105, which is connected to the power component 101 and the reduction component 102. The telescopic rod 103 passes through the support component 30 and is connected to the contact pad 104.

[0058] In the embodiments provided in this application, the components of the adjustment device 10 are connected sequentially according to the power transmission direction, and the number of each component is the same. In the embodiments provided in this application, the power component 101 drives the connecting component 105, so that the connecting component 105 drives the telescopic rod 103 to move (forward or backward) through the deceleration component 102, thereby causing the contact pad 104 to press or loosen the conductive rod 201. Here, the conductive rod 201 is in contact with the contact pad 104 on one side and pressed with the conductive frame 203 on the other side.

[0059] It should be noted that the power component 101 in the embodiments provided in this application may be specifically, but is not limited to, a servo motor. The servo motor is set at the upper end of the support frame and is used to accurately drive the connecting component 105 to rotate. The reduction component 102 in the embodiments provided in this application includes a worm gear and a worm. The connecting component 105 in the embodiments provided in this application may be specifically, but is not limited to, a coupling. The coupling is rotatably connected to the worm gear, and the worm gear is meshed with the worm, thereby realizing that the coupling drives the worm gear to rotate and adjusts the movement of the telescopic rod 103.

[0060] Compared with the prior art, the current regulating device 1 for the continuous anode of the aluminum electrolysis cell provided in this application embodiment is connected to the regulating device 10 via a conductive component 20 and to the anode component of the aluminum electrolysis cell via the conductive component 20. The regulating device 10 of the same group applies pressure or releases pressure to the anode component through the conductive component 20 to regulate the current density of the anode component. When the current density distribution of the continuous anode of the aluminum electrolysis cell is uneven, i.e., the local current density is high or low, the embodiment of this application controls the power component 101 to drive the connecting component 105, so that the connecting component 105 drives the telescopic rod 103 to move, i.e., move forward or backward, through the deceleration component 102. This causes the contact pad 104 to press or loosen the conductive rod 201, thereby adjusting the anode section where the current density deviation needs to be adjusted, so as to eliminate the uneven current density distribution in different areas. This can improve the problem of uneven current density distribution in the continuous anode component during electrolysis, and at the same time reduce the local overheating in different anode sections, thereby improving the electrolysis efficiency of the aluminum electrolysis cell.

[0061] Figure 3 This is a flowchart illustrating a method for adjusting the current of a continuous anode in an aluminum electrolysis cell, as provided in an embodiment of this application. For example,... Figure 3 As shown, the current regulation method for the continuous anode of an aluminum electrolysis cell includes the following steps:

[0062] S301. Obtain the current density data of the anode assembly of the aluminum electrolysis cell.

[0063] In this step, during the continuous anode assembly process of the aluminum electrolysis cell, the embodiment provided in this application first obtains the current density data of the anode assembly of the aluminum electrolysis cell based on the sensor in the sensing component, and sends the current density data to the external control host computer so that the external control host computer can determine in real time whether there are current density deviation points in the current density data, and determine the distribution state of the current density in real time according to the judgment result.

[0064] For example, the sensor is connected to an external control host computer.

[0065] S302. Based on current density data, control the regulating device to apply or release pressure to the anode assembly through the conductive component to regulate the current density of the anode assembly.

[0066] In this step, after the current density data is determined, the external control host computer analyzes and calculates the current density data to determine whether there is uneven current density distribution. If uneven current density distribution occurs, i.e., the current density of local anode zones is higher or lower, the control adjustment device is activated. This causes the power component to drive the connecting component, which in turn drives the telescopic rod to move forward or backward through the deceleration component. This causes the contact pad to press or loosen against the conductive rod, adjusting the pressing or loosening of the anode zone where the current density deviation needs to be adjusted. This ensures that the current density of the entire anode assembly is uniform, making the aluminum electrolysis cell condition more stable and reliable, and achieving smooth operation of the continuous anode in the aluminum electrolysis cell.

[0067] In one embodiment, where the conductor assembly includes a built-in conductor group comprising a plurality of conductors that space the anode assembly to form a plurality of anode partitions, and the adjustment device includes a sensing component, step S302 includes the following sub-steps:

[0068] Sub-step 3021: Based on the sensing component, obtain the actual current density data of the conductor in the anode component.

[0069] In this step, during the continuous anode assembly process of the aluminum electrolysis cell, the embodiment provided in this application first obtains the actual current density data detected by the anode assembly of the aluminum electrolysis cell through the sensor in the sensing component, and sends the current density data to the external control host computer so that the external control host computer can determine the distribution state of the current density of the anode assembly in real time.

[0070] Sub-step 3022: Based on the actual current density data and the preset current density threshold corresponding to the anode component, determine whether there is a current density deviation in the region corresponding to the conductor.

[0071] In this step, the embodiments provided in this application compare the actual current density data collected by each sensor with a preset current density threshold to determine whether the actual current density data is within the specified range of the preset current density threshold. If it is within the specified range, it is determined that there is no current density deviation in the area corresponding to the conductor; if it is not within the specified range, it is determined that there is a current density deviation in the area corresponding to the conductor.

[0072] Sub-step 3023: If there is a current density deviation in the anode zone, then based on the current density deviation, control the regulating device to apply pressure or release pressure to the anode zone with the current density deviation through the conductive component, so as to regulate the current density of the anode component.

[0073] In this step, if there is a current density deviation in any anode zone, the pressure change value that the anode zone needs to withstand is calculated and determined according to the magnitude of the current density deviation. Then, according to the pressure change value, the regulating device is controlled to control the power component to drive the connecting component, so that the connecting component drives the telescopic rod to move (forward or backward) through the deceleration component, thereby causing the contact pad to press or loosen from the conductive rod, thereby applying pressure or releasing pressure to the anode zone with current density deviation, so as to adjust the current density of the anode component.

[0074] The following are examples of current density applications during implementation:

[0075] For example, when the current load in the continuous anode of the aluminum electrolysis cell in the embodiment provided in this application is determined to be 20kA, aluminum electrolysis is performed using the continuous anode of the aluminum electrolysis cell. When the appearance of the anode assembly is detected, the current density on the left side is higher than 0.2A / cm. 2 The current density on the right side is 0.2 A / cm² lower. 2 At this time, the servo motors of the regulating devices 10a, 10d, 10c and 10f are started, and the servo motors of 10b and 10e are turned off. At this time, the left servo motor drives the connecting assembly, which causes the connecting assembly to move the telescopic rod backward through the deceleration assembly, thereby causing the contact pad to loosen from the conductive rod and eliminating the phenomenon of high current density distribution on the left side; at the same time, the right servo motor drives the connecting assembly, which causes the connecting assembly to move the telescopic rod forward through the deceleration assembly, thereby causing the contact pad to press against the conductive rod and eliminating the phenomenon of low current density distribution on the left side, so that the continuous anode assembly achieves uniform current density distribution during electrolysis.

[0076] For example, when the current load in the continuous anode of the aluminum electrolysis cell in the embodiment provided in this application is determined to be 186kA, aluminum electrolysis is performed using the continuous anode of the aluminum electrolysis cell. When the appearance of the anode assembly is detected, the current density on the left side is lower than 0.3A / cm. 2 The current density in the middle section is 0.1 A / cm² higher. 2 The current density on the right side is 0.2 A / cm² higher. 2 When the servo motors of the regulating devices 10a, 10b, 10c, 10d, 10e, and 10f are activated, the left servo motor drives the connecting assembly, causing the connecting assembly to move the telescopic rod forward through the deceleration assembly, thereby causing the contact pad to press against the conductive rod and eliminating the phenomenon of high current density distribution on the left side. At the same time, the middle and right servo motors drive the connecting assembly, causing the connecting assembly to move the telescopic rod backward through the deceleration assembly, thereby causing the contact pad to loosen from the conductive rod and eliminating the phenomenon of low current density distribution on the left side, so that the continuous anode assembly achieves uniform current density distribution during electrolysis.

[0077] It should be noted that the sum of the current density deviations on the left, middle, and right sides in the two application examples is 0.

[0078] This application provides a current regulation method for the continuous anode of an aluminum electrolytic cell. Compared with the prior art, the embodiment provided by this application obtains the current density data of the anode assembly of the aluminum electrolytic cell and controls the regulating device based on the current density data. The device applies or releases pressure to the anode assembly through the conductive component to regulate the current density of the anode assembly. When the current density distribution of the continuous anode of the aluminum electrolytic cell is uneven, the embodiment provided by this application controls the power component to drive the connecting component, so that the connecting component drives the telescopic rod to move, i.e., move forward or backward, through the deceleration component. This causes the contact pad to press or loosen from the conductive rod, eliminating the uneven current density distribution in different areas. This can improve the problem of uneven current density distribution in the continuous anode assembly during electrolysis, reduce the local overheating in different anode zones, and improve the electrolysis efficiency of the aluminum electrolytic cell.

[0080] Memory 420 stores machine-readable instructions executable by processor 410. When electronic device 400 is running, processor 410 and memory 420 communicate via bus 430. When the machine-readable instructions are executed by processor 410, they can perform the operations described above.
