The term "more than two" includes two or more than two situations.

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

[0036] At present, in the process of aluminum electrolysis using continuous anodes, due to the adoption of a special current-inducing structure, when the anode is powered on, uneven current density distribution will occur, resulting in problems such as reduced electrolysis efficiency.

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

[0038] Figure 1 A top view of a current regulating device for a continuous anode of an aluminum electrolysis cell provided in an embodiment of the present application. Figure 1 As shown, the current regulating device 1 for the continuous anode of the aluminum electrolytic cell includes: a plurality of regulating devices 10 and a conductive component 20, wherein the conductive component 20 is transmission-connected to the regulating device 10, and the conductive component 20 is connected to the anode component of the aluminum electrolytic cell, and the conductive component 20 is located between the regulating device 10 and the anode component, and is used for conducting ionization of the continuous anode of the aluminum electrolytic cell.

[0039] The specific number of the regulating devices 10 in the embodiment provided in the present 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 an aluminum electrolytic cell with a larger current load, the embodiments provided in the present application may be provided with at least 6 regulating devices 10; and for an electrolytic cell with a smaller current load, the embodiments provided in the present application may be provided with at least 4 regulating devices 10.

[0041] It should be noted that current load refers to the amount of current consumed in the working state, usually in amperes (Ampere, A) as the unit, indicating the strength of the current. The magnitude of the current load is closely related to the power in the working state. The greater the power, the greater the current1.

[0042] In some examples, at least two adjustment devices 10 form a group, and at least two adjustment devices 10 in a group of adjustment devices 10 are respectively arranged on opposite sides of the anode assembly, and the adjustment devices 10 in the same group apply pressure to or release pressure on the anode assembly through the conductive assembly 20 to adjust the current density of the anode assembly, wherein the structures of at least two adjustment devices 10 in the same group can be exactly the same, and the structures of the adjustment devices 10 between different groups can also be exactly the same.

[0043] The regulating device 10 in the embodiment provided in the present application is used to adjust the pressure between the conductive component 20 and the anode component; the principle of forming at least two regulating devices 10 into a group and arranging at least two regulating devices 10 in a group of regulating devices 10 on opposite sides of the anode component is to perform zoned regulation of the current density of the anode component during the electrolysis process; the present application connects the conductive component 20 with the regulating device 10 in a transmission manner, and when it is detected that the current density of the continuous anode of the aluminum electrolytic cell is unevenly distributed, the regulating device 10 is used to press or loosen the conductive component 20, change the pressure between the regulating conductive component 20 and the anode component, and then change the resistance between the regulating conductive component 20 and the anode component. Since the voltage is a fixed voltage value applied externally, according to Ohm's law, when the voltage is constant, if the resistance between the regulating conductive component 20 and the anode component changes, then the current density distribution between the conductive component 20 and the anode component will also change, thereby achieving the improvement of the uneven current density distribution problem of the continuous anode component during the electrolysis process and improving the electrolysis efficiency of the aluminum electrolytic cell.

[0044] It should be noted that when the pressure between the conductive component 20 and the anode component is increased, it is determined that the resistance between the conductive component 20 and the anode component decreases. At this time, it is determined that the current density distribution between the conductive component 20 and the anode component increases, and it is possible to enhance the current density distribution between the conductive component 20 and the anode component; when the pressure between the conductive component 20 and the anode component is decreased, it is determined that the resistance between the conductive component 20 and the anode component increases. At this time, it is determined that the current density distribution between the conductive component 20 and the anode component decreases, and it is possible to reduce 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 embodiment provided in the present application is specifically set to 4 or 6, and the 4 or 6 adjustment devices 10 are respectively arranged in groups of two, and the two adjustment devices in each group are respectively arranged on the opposite sides (on two opposite sides) of the anode assembly to adjust the current density distribution of the anode assembly.

[0046] The electrolytic cell in the embodiments provided in the present application is composed of a cell body, an anode and a cathode. Most of the anode chamber and the cathode chamber are separated by a diaphragm. The electrolytic cell 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 electricity passing through a unit area per unit time. Its direction vector is the normal vector of the corresponding cross-section per unit area. The direction of its direction vector is determined by the direction of the positive charge passing through this cross-section.

[0048] In some examples, the conductive component 20 includes a plurality of conductive rods 201, a built-in conductor group 202, and a conductive frame 203, wherein the plurality of conductors of the built-in conductor group 202 are embedded in the anode component, the conductive frame 203 is fixedly disposed on the outer wall of the anode component, the conductive rod 201 is connected to the outer side 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 fitted with the adjustment device 10, wherein the number of the conductive rods 201 is the same as the number of the adjustment devices 10, and corresponds one to one.

The discontinuous manner can be specifically provided with a plurality of openings on the conductive frame 203, and an insulating component 40 is provided in each opening, that is, the insulating component 40 is tightly connected with the conductive frame 203 at the opening, and the insulating component 40 in the embodiment provided in the present application is also evenly distributed on the outside of the anode component, and can be specifically provided on two opposite sides of the outside of the anode component, and the insulating component 40 and the conductor are spaced apart, so that any two adjacent insulating components 40 can space the anode component into several parts, that is, multiple anode partitions, to facilitate the control of current density distribution.

[0050] Any anode partition in the embodiments provided in the present application is a relatively independent area, which is convenient for the sensor in the sensing assembly to detect the current density. In the embodiments provided in the present application, the position of the insulating assembly 40 cannot be on the same straight line as the conductor, and the number of insulating assemblies 40 is 2 less than the number of adjusting devices 10.

[0051] In some examples, the adjustment device 10 includes a sensor assembly, and a plurality of sensors in the sensor assembly are electrically connected to a conductor. Here, the plurality of conductors separate the anode assembly into a plurality of anode partitions, and the sensors are used to detect current density of the anode partitions.

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

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

[0054] It should be noted that the support assembly 30 is installed around the outer wall of the anode group and is 20-50 cm away from the anode assembly, and more than four adjustment devices 10 are respectively installed at different positions of the support assembly 30, and in the embodiment provided in the present application, the support assembly 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 assembly in the aluminum electrolytic cell.

[0055] It should be noted that the support assembly 30 in the embodiment provided in the present application may specifically be but not limited to a support frame.

[0056] In some examples, in order to improve the adjustment accuracy of the current density of the anode assembly, the data of the adjustment device 10 can be determined to be 6. At this time, it is determined that the 6 adjustment devices 10 are grouped in pairs and arranged on opposite sides of the support frame, and the 6 adjustment devices 10 are evenly spaced and distributed on opposite sides of the anode assembly, respectively located on the upper left side (such as Figure 1 10a position), the middle of the upper side (such as Figure 1 10b position), upper right side (such as Figure 1 10c position), lower left side (such as Figure 1 10d position), the lower middle (such as Figure 1 10e) and the lower right side (such as Figure 1 For the convenience of distinction, the adjusting devices 10 at the above six positions are respectively denoted as 10a (upper left side), 10b (upper middle side), 10d (upper right side), 10c (lower left side), 10e (lower middle side) and 10f (lower right side), and the setting of the adjusting device 10 will not affect the normal operation of other equipment hot pot components of the continuous anode electrolyzer.

Figure 2 As shown, the adjustment device 10 includes a power component 101, a deceleration component 102, a telescopic rod 103 and a contact pad 104.

The adjustment device 10 also includes a connecting component 105, which is connected to the power component 101 and the deceleration component 102. The telescopic rod 103 passes through the support component 30 and is connected to the contact pad 104.

[0058] The various components in the adjustment device 10 in the embodiment provided in the present application will be connected in sequence according to the power transmission direction, and the number of the above-mentioned partial components is the same. In the embodiment provided in the present application, the power component 101 drives the connection component 105, so that the connection component 105 drives the telescopic rod 103 to move (forward or backward) through the deceleration component 102, thereby driving 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.

[0060] The current regulating device 1 for continuous anodes of an aluminum electrolytic cell provided in an embodiment of the present application, compared with the prior art, is connected to the regulating device 10 through a conductive component 20, and the conductive component 20 is connected to the anode component of the aluminum electrolytic cell, and the regulating device 10 of the same group applies pressure to or releases pressure on the anode component through the conductive component 20 to adjust the current density of the anode component. In the embodiment provided by the present application, when uneven current density distribution occurs in the continuous anode of the aluminum electrolytic cell, that is, the local current density is high or low, the power component 101 is controlled to drive the connecting component 105, so that the connecting component 105 drives the telescopic rod 103 to move, that is, move forward or backward, through the deceleration component 102, thereby driving the contact pad 104 to press or loosen the conductive rod 201, and the anode partitions that need to adjust the current density deviation are adjusted to be pressed or loosened, so as to eliminate the uneven current density distribution in different areas, which can improve the problem of uneven current density distribution of the continuous anode assembly during the electrolysis process, and at the same time reduce the local overheating in different anode partitions, thereby improving the electrolysis efficiency of the aluminum electrolytic cell.

[0061] Figure 3 This is a flow chart of a method for regulating the current of a continuous anode of an aluminum electrolysis cell provided in an embodiment of the present application. Figure 3 As shown, the current regulation method of the continuous anode of the aluminum electrolysis cell includes the following steps:

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

[0063] In this step, during the continuous anode assembly operation of the aluminum electrolytic cell, the embodiment provided in the present application first obtains the current density data of the anode assembly of the aluminum electrolytic cell based on the sensor in the sensor assembly, and sends the above current density data to an external control host computer, so that the external control host computer can judge in real time whether there are current density deviation points in the current density data, and calculate the distribution status of the current density in real time according to the judgment result.

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

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

[0066] In this step, after the current density data is determined, an external control host computer performs data analysis and calculation on the current density data to determine whether there is an uneven current density distribution, and when the current density distribution is uneven, that is, the current density of the local anode partition is higher or lower, the adjustment device is controlled to make the power component drive the connecting component, so that the connecting component drives the telescopic rod to move through the deceleration component, that is, move forward or backward, thereby driving the contact pad to press or loosen the conductive rod, and adjust the tightening or loosening of the anode partition that needs to adjust the current density deviation, so that the current density of the entire anode assembly is uniform, the cell condition of the aluminum electrolytic cell is more stable and reliable, and the smooth operation of the continuous anode of the aluminum electrolytic cell is achieved.

[0067] In one embodiment, when the conductor assembly includes a built-in conductor group, the built-in conductor group includes a plurality of conductors, the plurality of conductors separate the anode assembly to form a plurality of anode partitions, and the adjustment device includes a sensor assembly, step S302 includes the following sub-steps:

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

[0069] In this step, during the continuous anode assembly operation of the aluminum electrolytic cell, the embodiment provided in the present application first obtains the actual current density data actually detected by the anode assembly of the aluminum electrolytic cell through the sensor in the sensor assembly, and sends the above current density data to an 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 a preset current density threshold corresponding to the anode assembly, determine whether there is a current density deviation in the area corresponding to the conductor.

[0071] In this step, the embodiment provided in the present application compares the actual current density data collected by each sensor with the preset current density threshold to determine whether the actual current density data is within the provisions of the preset current density threshold. If it is within the provisions, it is determined that there is no current density deviation in the area corresponding to the conductor; if it is not within the provisions, 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 partition, based on the current density deviation, the regulating device is controlled to apply pressure or release pressure to the anode partition with the current density deviation through the conductive component to adjust the current density of the anode component.

[0073] In this step, if there is a current density deviation in any anode partition, the pressure change value that the anode partition is required to withstand is calculated and determined based on the magnitude of the current density deviation, and then the regulating device is controlled based on the pressure change value 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 driving the contact pad to press or loosen the conductive rod, thereby achieving pressure being applied to or released from the anode partition with the current density deviation to adjust the current density of the anode assembly.

[0074] Examples of current density applications during implementation are as follows:

[0075] For example, when the current load in the continuous anode of the aluminum electrolysis cell in the embodiment provided in the present application is determined to be 20 kA, the continuous anode of the aluminum electrolysis cell is used for aluminum electrolysis, and when the current density on the left side of the anode assembly is detected to be higher than 0.2 A / cm 2 The current density on the right side is 0.2A / cm lower 2 , 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 servo motor on the left side drives the connecting assembly, so that the connecting assembly drives the telescopic rod to move backward through the deceleration assembly, thereby driving the contact pad to loosen the conductive rod, eliminating the high current density distribution on the left side; at the same time, the servo motor on the right side drives the connecting assembly, so that the connecting assembly drives the telescopic rod to move forward through the deceleration assembly, thereby driving the contact pad to press the conductive rod, eliminating the low current density distribution on the left side, so that the continuous anode assembly achieves uniform current density distribution during the electrolysis process.

[0076] For example, when the current load in the continuous anode of the aluminum electrolysis cell in the embodiment provided in the present application is determined to be 186 kA, the continuous anode of the aluminum electrolysis cell is used for aluminum electrolysis, and when the current density on the left side of the anode assembly is detected to be lower than 0.3 A / cm 2 , the current density in the middle part is 0.1A / cm higher 2 , the current density on the right is 0.2A / cm higher 2 , the servo motors of the adjusting devices 10a, 10b, 10c, 10d, 10e and 10f are started. At this time, the servo motor on the left side drives the connecting assembly, so that the connecting assembly drives the telescopic rod to move forward through the deceleration assembly, thereby driving the contact pad to press the conductive rod, eliminating the high current density distribution on the left side; at the same time, the servo motors in the middle and right sides drive the connecting assembly, so that the connecting assembly drives the telescopic rod to move backward through the deceleration assembly, thereby driving the contact pad to loosen the conductive rod, eliminating the low current density distribution on the left side, so that the continuous anode assembly achieves uniform current density distribution during the electrolysis process.
