For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0023] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] In some embodiments, the alumina feeding control of the electrolytic cell is achieved by automatically analyzing the slope change of the cell resistance using a cell control machine to control the feeding rate, thereby balancing the alumina concentration at each feeding point in the electrolytic cell, suppressing the alumina effect, and improving current efficiency. However, in actual production, unexpected situations such as major overhauls and power outages of the cell control machine, power supply system failures, and damage to internal components caused by regional lightning strikes frequently occur. These situations can easily lead to a complete loss of control over the cell control system, causing the cell control machine to lose its core control functions of automatic shell breaking and automatic feeding. It will then be unable to continue performing alumina concentration balancing control, and the electrolytic cell will be prone to localized material shortages, leading to frequent occurrences of the alumina effect that is difficult to extinguish. This could potentially cause cell leakage accidents, seriously affecting the safety of the electrolytic series.

[0025] In the event of a malfunction in the cell control unit, the relevant technology typically involves installing a simple pneumatic control cabinet next to the control unit. Once the control unit malfunctions, the valves in the pneumatic control cabinet are manually operated at regular intervals to release material into the electrolytic cell at the feeding point. Alternatively, manual pushing of material into the feeding point or manual operation of the solenoid valve using a shell-breaking control valve simultaneously releases material into the electrolytic cell at the same time can compromise the uniformity of alumina concentration in the electrolytic cell, leading to significant sedimentation at the bottom of the furnace, damaging the furnace chamber, and affecting the stability of the electrolytic cell's operation. Furthermore, this method requires on-site workers, increasing labor intensity and labor costs. A single-point, rotating shell-breaking method can also be used, but the shell-breaking solenoid valves are all installed on top of the electrolytic cell. In the event of a malfunction, workers must climb to the top of the cell to open the valves one by one to feed material into the electrolytic cell, resulting in high labor intensity, high operational risks, and safety hazards. These methods cannot achieve balanced feeding at all points in the electrolytic cell, and the uniformity of alumina concentration in the electrolytic cell cannot be guaranteed. The uncontrolled alumina concentration in the electrolytic cell significantly affects the stability of the cell condition. Furthermore, the simultaneous shelling and feeding at each feeding point increases the consumption of compressed air, leading to fluctuations in air source pressure, which further aggravates abnormal operation of the actuator and creates a vicious cycle of production failure.

[0026] To address the current issue of aluminum electrolysis systems typically using a simple pneumatic control cabinet installed next to the cell control unit, which requires manual intervention to periodically operate the cabinet valves to discharge material to the electrolytic cell in case of machine malfunction, this method relies on manual monitoring and operation, resulting in significant response delays and a high risk of sedimentation at the bottom of the electrolytic cell, potentially inducing the anode effect. This application provides an emergency shell-breaking and material-discharging system for aluminum electrolysis cells.

[0027] like Figure 1As shown, an embodiment of this application provides an emergency shell-breaking and feeding system for aluminum electrolytic cells. The system includes: an emergency shell-breaking and feeding device 11 and an electrolytic cell actuator 12. The emergency shell-breaking and feeding device 11 is used to determine the feeding data corresponding to the electrolytic cell based on the online data collected by the electrolytic cell when the operating condition of the electrolytic cell is detected to be abnormal, generate a feeding control command corresponding to the feeding data, and send the feeding control command to the electrolytic cell actuator 12. The emergency shell-breaking and feeding device 11 is used to control at least one electrolytic cell. The electrolytic cell actuator 12 is used to receive the feeding control command sent by the emergency shell-breaking and feeding device 11 and perform single-point uniformity automatic control of the electrolytic cell according to the feeding control command.

[0028] In some embodiments, the emergency shell-breaking and feeding device 11 can control one or more electrolytic cells to operate synchronously according to on-site needs, and receive online data collected by the electrolytic cells during the production process. Based on the online data collected, the device can determine the operating condition of the electrolytic cells. When it is determined that the operating condition is abnormal, the device can calculate the feeding data corresponding to the electrolytic cells, generate the feeding control command corresponding to the feeding data, drive the electrolytic cell actuator 12 to perform the corresponding control operation, adjust the operating condition of the electrolytic cells to the normal operating condition, thereby achieving balanced control of the alumina concentration in the electrolytic cells and ensuring the safety of the electrolysis series.

[0029] Specifically, the online data acquisition can be real-time operating data of at least one electrolytic cell, including cell voltage, cell resistance, current, cell control system operating status, alumina concentration in the cell, shell-breaking status, feeding status, emergency power supply status, feeding action signal, and shell-breaking action signal for each electrolytic cell. Feeding data can include feeding point, feeding quantity, feeding time (including feeding trigger time and feeding duration), feeding interval, and shell-breaking time (including shell-breaking trigger time and shell-breaking duration) for each electrolytic cell. Based on the online data acquisition, the operating conditions of each electrolytic cell can be detected and judged, and feeding control commands can be generated based on the feeding data to control the uniformity of feeding across multiple electrolytic cells.

[0030] In some embodiments, the electrolytic cell actuator 12 serves as the action execution terminal in the emergency shell-breaking and feeding system. It can receive the feeding control command issued by the emergency shell-breaking and feeding device 11 in real time, and immediately execute specific operations such as shell breaking and feeding according to the action sequence based on the feeding control command. By controlling each feeding point of the electrolytic cell point by point and taking turns to act, it realizes the automatic control of the single-point uniformity of alumina feeding in the electrolytic cell, ensuring that alumina is evenly distributed in the electrolytic cell, avoiding local material shortages or excessive accumulation, ensuring that the electrolytic cell can still operate stably and safely in the emergency working condition of the cell control system failure, and immediately executing the corresponding feeding control operation when receiving the feeding control command, reducing the lag in emergency control.

[0031] The feeding control command can be an electrical signal command issued by the emergency shell-breaking feeding device 11 to each actuator, controlling the timing and processing interval of different feeding operations (such as the shell-breaking operation at the feeding point and the quantitative alumina dispensing operation). The timing can be preset to execute the shell-breaking operation at the feeding point first, followed by the quantitative alumina dispensing operation; the processing interval can be preset according to production needs.

[0032] Correspondingly, the electrolytic cell actuator 12 can perform single-point alternating actions for multiple feeding points of the electrolytic cell, reducing the problems of excessive compressed air loss and uneven alumina distribution caused by synchronous feeding, realizing automatic control of single-point uniformity, effectively avoiding faults such as furnace bottom sedimentation and anode effect, and ensuring the continuous and stable operation of the electrolytic cell under emergency conditions.

[0033] In this way, the emergency shell-breaking and feeding device 11 in this embodiment can acquire online data from each electrolytic cell in real time and determine the operating condition of the electrolytic cell. When it is determined that the operating condition of the electrolytic cell is abnormal, it generates a feeding control command corresponding to the feeding data based on the online data, and drives the electrolytic cell actuator 12 to perform single-point uniformity automatic control of the electrolytic cell in a timely manner according to the feeding control command. This realizes automatic feeding processing under abnormal conditions, without the need for manual monitoring and feeding, improving the feeding control response efficiency, ensuring the alumina concentration in the electrolytic cell is balanced, avoiding furnace bottom sedimentation and the occurrence of anode effect, ensuring that the electrolytic cell can still operate stably in emergency conditions, and ensuring the safety of the electrolysis series.

[0034] Furthermore, as a refinement and extension of the specific implementation of the above embodiments, and to fully illustrate the implementation of this embodiment, optionally, the emergency shell-breaking and unloading device 11 includes an intelligent processing module 111. The intelligent processing module 111 is used to monitor the operating condition of the electrolytic cell using an online data detection intelligent algorithm based on the online collected data corresponding to the electrolytic cell. When an abnormal operating condition of the electrolytic cell is detected, the module determines the unloading data corresponding to the electrolytic cell based on the online collected data and generates an unloading control command corresponding to the detected unloading data. Abnormal operating conditions include the electrolytic cell being unable to shell-break and unload, the original cell control system corresponding to the electrolytic cell being out of control, and the alumina concentration in the electrolytic cell being uneven. The intelligent processing module 111 is also used to adjust the action sequence and processing interval corresponding to the electrolytic cell actuator 12.

[0035] In some embodiments, the intelligent processing module 111 may embed an online data detection intelligent algorithm. During the operation of each electrolytic cell, the intelligent processing module 111 can detect the current cell voltage signal and the current cell feeding action signal in real time to detect the current feeding interval of the electrolytic cell. The current feeding interval is compared with the normal feeding interval to determine the feeding interval multiple of the current feeding interval relative to the normal feeding interval, as well as the voltage change trend of the current cell voltage signal, such as the slope of the cell voltage rise / fall. Based on the U-shaped electrolyte concentration-voltage law corresponding to each electrolytic cell, the correlation factor between the feeding interval multiple and the voltage change trend is continuously and dynamically evaluated to determine the evaluation factor corresponding to the current electrolytic cell, such as the low concentration area factor (the feeding interval multiple is strongly correlated with the voltage change trend or there is a voltage effect trend) and the high concentration area factor (the feeding interval multiple is not correlated with the voltage change trend or is inversely correlated).

[0036] Specifically, the system can first identify and eliminate interference from anode operation (voltage surge), mark factors near low concentration areas and factors near high concentration areas, and determine the dynamic relevant factor area under normal operating conditions; identify the current feeding status based on the current feeding interval multiple, such as overfeeding or underfeeding; determine whether the electrolytic cell is in an abnormal operating condition based on the current feeding status and evaluation factors; if it is determined that the electrolytic cell is in an abnormal operating condition, such as a feeding system failure, the intelligent processing module 111 can activate the alarm mechanism and take over the feeding control authority of the electrolytic cell.

[0037] For example, if a low-concentration factor is detected during excessive feeding, or a high-concentration factor is detected during insufficient feeding, and the current shell-breaking feeding action is determined to be normal based on the current electrolytic cell feeding action signal and the current electrolytic cell shell-breaking action signal, it indicates that the current feeding system has malfunctioned and the electrolytic cell is in an abnormal operating condition. The intelligent processing module 111 will activate an alarm, send an alarm message to the display module 15, take over the feeding control authority, automatically determine the feeding strategy corresponding to each electrolytic cell, and generate the corresponding feeding control command.

[0038] For example, when the algorithm detects that a single cell cannot be shelled and unloaded, the emergency shelling and unloading system for aluminum electrolysis cells is directly activated to control the on-demand single-point automatic shelling and unloading function of the electrolysis cells. Specifically, when it is detected that the cell voltage is higher than 3.6V and a single cell or series of electrolysis cells cannot be shelled and unloaded, the intelligent shelling and unloading system can be directly activated to control the on-demand single-point automatic shelling and unloading function of the electrolysis cells. The intelligent processing module 111 can also provide functions such as shelling, unloading, processing interval adjustment, unloading method, and manual / automatic selection of electrolysis cells and issue corresponding control commands. It provides electrolysis cells with functions such as shelling, unloading, processing interval, and unloading method selection, and can realize multiple unloading methods such as manual, single-point, and alternating shelling. Operators can set the processing interval, shelling, unloading time, and shelling and unloading interval according to the needs of the site.

[0039] By intelligently analyzing online data from the electrolytic cells, the system automatically controls the uniformity of material feeding at each point. This ensures normal shell breaking and feeding in electrolytic cells even when the cell control system malfunctions, preventing major production safety accidents such as high energy consumption, high carbon emissions, and cell leakage caused by material shortages. Furthermore, the system features intelligent algorithms, simple operation, lightweight design, high stability, and strong anti-interference capabilities. It can quickly solve the problem of manual shell breaking and feeding required in cases of cell control system malfunctions, such as major maintenance shutdowns, power supply system failures, regional lightning strikes causing malfunctions, and internal faults. This achieves uniform control of alumina concentration in the electrolytic cells under abnormal cell control conditions, maintaining material balance and stability of the electrolytic cells.

[0040] Optionally, the electrolytic cell actuator 12 includes a shell-breaking cylinder and a feeding cylinder; the shell-breaking cylinder is used to perform a shell-breaking operation at the feeding point according to the action sequence and processing interval when receiving the feeding control command; the feeding cylinder is used to perform a quantitative alumina feeding operation according to the action sequence and processing interval when receiving the feeding control command.

[0041] In some embodiments, after receiving the corresponding feeding control command, the shell-breaking cylinder can be driven to impact downwards, breaking the shell on the electrolyte surface, opening a channel for feeding, and completing the shell-breaking operation at the feeding point. After the shell is opened, the extension and retraction stroke and start-stop duration of the feeding cylinder can be precisely controlled according to the preset action sequence and processing interval. The reciprocating motion of the feeding cylinder drives the opening and closing of the feeding valve to complete a single quantitative alumina feeding operation. After feeding is completed, the feeding valve is immediately reset and closed to avoid excessive alumina spillage and accumulation.

[0042] Optionally, the emergency shell-breaking and unloading device 11 also includes function buttons; the function buttons are arranged on the housing panel of the emergency shell-breaking and unloading device 11 and are used to switch the system control mode. The function buttons include a manual / automatic switching button, a shell-breaking control button, an unloading control button, and a power control button; multiple knock-out holes are arranged on different sides of the emergency shell-breaking and unloading device 11.

[0043] In some embodiments, human-computer interaction can be achieved through at least one configured function button, such as... Figure 2 As shown, operators can switch modes and manually intervene using function buttons. Pressing the manual / automatic switch button will switch the system to manual control mode or emergency automatic control mode. Alternatively, pressing the shell-breaking control button, material feeding control button, and power control button will manually trigger shell-breaking and material feeding actions, as well as system start / stop control, to adapt to the operation requirements of different operating conditions.

[0044] Optionally, the system also includes an emergency power supply module 13; the emergency power supply module 13 is used to switch the power supply circuit to supply power to the emergency shelling and feeding device 11 when the operating condition of the electrolytic cell is detected to be an emergency condition.

[0045] In some embodiments, the emergency power supply module 13 supplies power to the emergency shelling and unloading system of the aluminum electrolysis cell when the original cell control system malfunctions. The emergency power supply module 13 can be powered by an independent UPS. When the cell control system is under normal control, it is in a charging state. Once a single cell, area, or system experiences a control or power supply abnormality, it is immediately activated and ready to use. Alternatively, it can be implemented in other ways that can achieve the same function.

[0046] Specifically, the emergency power supply monitors the power supply status of the original cell control system in real time. If the cell control system is found to be out of control, the power supply circuit is switched immediately to provide uninterrupted emergency power supply to the emergency shell-breaking and feeding device 11, display module 15, button module, MOS tube drive circuit and electrolytic cell actuator 12. This ensures that the emergency control link is powered on and running normally, so as to achieve uniform control of the alumina concentration in the electrolytic cell under abnormal cell control machine conditions, thereby maintaining the material balance and stability of the electrolytic cell.

[0047] Optionally, the emergency power supply module 13 includes a UPS emergency power supply 131; the UPS emergency power supply 131 adopts an instant-on working mode, which is used to immediately activate when the electrolytic cell is in an emergency working condition, and to supply power to the emergency shell-breaking and feeding device 11.

[0048] In some embodiments, the UPS emergency power supply 131 can be used to immediately start in emergency situations, supplying power to components such as the emergency shell-breaking and feeding device 11, actuators, and button / display module 15 via power supply and signal transmission cables. Specifically, when the original cell control system is normally controlling the electrolytic cell, the UPS emergency power supply 131 is in a charging state, maintaining a fully charged state. When the aluminum electrolytic cell emergency shell-breaking and feeding system detects a loss of control of the cell control system due to major maintenance power outage, power supply system failure, regional cell control machine lightning strike loss of control, or internal fault power outage of the cell control machine, i.e., in an emergency situation, the UPS emergency power supply 131 of the electrolytic enterprise is immediately and automatically activated, supplying power to one or more electrolytic cell emergency intelligent shell-breaking and feeding systems via power supply cables. Correspondingly, when the emergency power supply module 13 detects that the original cell control system has been repaired, it can automatically switch back to the original power supply circuit.

[0049] For example, such as Figure 3 As shown, in emergency situations, the UPS power supply configured in the low-voltage power distribution room can be used to power multiple emergency shell-breaking and feeding devices 11 on site, as well as the electrolytic cell actuators 12 corresponding to the multiple emergency shell-breaking and feeding devices 11.

[0050] Optionally, the system also includes a signal transmission module 14, which includes a power supply and signal transmission cable. The power supply and signal transmission cable is used to transmit the cell voltage detection signal and feeding control command corresponding to the electrolytic cell, as well as to drive the UPS emergency power supply 131. The cell voltage detection signal is used to monitor the operating condition of the electrolytic cell.

[0051] In some embodiments, the power supply and signal transmission cables can be integrated multi-core cables, which can transmit the cell voltage detection signal corresponding to the online acquired data to the emergency shell-breaking and feeding device 11 in real time. This provides data support for the device to determine the operating conditions of the electrolytic cell and identify emergency needs. After determining the operating conditions and generating a feeding control command, the control signal corresponding to the command is transmitted to the electrolytic cell actuator 12. The device connects the emergency shell-breaking and feeding device 11, the electrolytic cell actuator 12, and the emergency power supply module 13 to drive the UPS emergency power supply 131 in emergency situations. The UPS emergency power supply 131 provides timely power to other modules and devices, realizing the physical connection and signal transmission between various modules, and has the dual functions of signal transmission and auxiliary power supply. For example, the signal transmission module 14 can transmit the feeding control command issued by the intelligent processing module 111 to the electrolytic cell actuator 12 and display it in an emergency through the client in the display module 15.

[0052] Optionally, the signal transmission module 14 also includes a MOSFET; the MOSFET is used to receive the control signal corresponding to the feeding control command transmitted by the power supply and signal transmission cable, and to perform action timing control on the electrolytic cell actuator 12.

[0053] In some embodiments, the emergency shell-breaking and unloading device 11 can analyze the unloading requirements based on the collected online data such as cell resistance and cell voltage, generate corresponding shell-breaking and unloading control commands, and transmit stable drive signals to the electrolytic cell actuator 12 through the MOS transistor drive circuit to drive the electrolytic cell actuator 12 to perform specific operations. It can precisely control the circuit conduction timing and has the characteristics of low power consumption, fast response, and strong anti-interference under low voltage, avoiding the problems of lag response and contact sticking of traditional switching devices.

[0054] Optionally, the system also includes a display module 15; the display module 15 is used to display the corresponding operating condition information of the electrolytic cell in real time based on the online collected data when the operating condition of the electrolytic cell is an emergency operating condition.

[0055] The display module 15 can be connected to the emergency shell-breaking and feeding device 11 and the emergency power supply module 13 via the signal transmission module 14.

[0056] In some embodiments, the display module 15 can be a client configured for the emergency shell-breaking and feeding system of aluminum electrolytic cells, serving as a human-machine interface display unit to display the system's operating status and the electrolytic cell's working condition in real time. When the emergency shell-breaking and feeding device 11 determines that the electrolytic cell is in an emergency working condition, the key working condition information is displayed intuitively based on the real-time collected electrolytic cell operating data, facilitating the staff's intuitive determination of the electrolytic cell's status and ensuring that the emergency process is safe, controllable, and monitorable. The working condition information may include cell voltage, cell current, operating mode (automatic / manual / emergency), shell-breaking status, feeding status, power supply status, emergency power supply status, fault prompts, etc.

[0057] In this way, when the original cell control system loses power or becomes uncontrollable, and the system enters emergency control mode, the display module 15 can display the current operating status information of the electrolytic cell in real time based on the real-time online data. This allows staff to intuitively and quickly grasp the operating status of the electrolytic cell under emergency conditions through the display module 15, without having to climb to the top of the electrolytic cell for observation. This improves the safety and convenience of emergency handling, provides reliable data support and visual monitoring for on-site emergency production, and realizes the transformation from manual to intelligent automatic shell-breaking and unloading of materials in the event of abnormal power loss or uncontrollability of the cell control system. This fills the gap in maintaining the material balance of the electrolytic cell even when the electrolytic cell control system is out of control.

[0058] Compared with related technologies, this embodiment utilizes the online data detection intelligent algorithm in the intelligent processing module 111 to monitor the operating condition of the electrolytic cell based on the online collected data. When an abnormal operating condition is detected, the corresponding feeding data is determined based on the online collected data, and a feeding control command corresponding to the detected feeding data is generated. Furthermore, when the emergency power supply module 13 detects an emergency operating condition, it switches the power supply circuit to supply power to the emergency shell-breaking and feeding device 11. Simultaneously, the display module 15 displays the operating condition information of the electrolytic cell in real time, thereby enabling... When the cell control system malfunctions, the emergency power supply module 13 supplies power to the emergency shell-breaking and feeding system of the aluminum electrolytic cell. Through online data detection and intelligent algorithms, feeding control commands are generated to drive the electrolytic cell execution mechanism to perform single-point uniform feeding of the electrolytic cell, ensuring stable operation of the electrolytic cell. This quickly solves the problem of manual shell-breaking and feeding required when the original cell control system malfunctions, such as major maintenance power outages, power supply system failures, regional cell control machine lightning strikes, or internal faults in the cell control machine. It achieves uniform control of the alumina concentration in the electrolytic cell under abnormal cell control conditions, maintaining the material balance and stability of the electrolytic cell.

[0059] Those skilled in the art will understand that the physical device structure provided in this embodiment does not constitute a limitation on the physical device, and may include more or fewer components, or combine certain components, or have different component arrangements.

[0060] Through the above description of the embodiments, those skilled in the art can clearly understand that this application can be implemented by means of software plus necessary general-purpose hardware platform, or it can be implemented by hardware. By applying the solution of this embodiment, compared with related technologies, this application utilizes the online data detection intelligent algorithm in the intelligent processing module 111 to monitor the operating condition of the electrolytic cell based on the online acquisition data corresponding to the electrolytic cell. When an abnormal operating condition of the electrolytic cell is detected, the corresponding feeding data of the electrolytic cell is determined based on the online acquisition data, and a feeding control command corresponding to the detected feeding data is generated. When the emergency power supply module 13 detects that the operating condition of the electrolytic cell is an emergency condition, the power supply circuit is switched to supply power to the emergency shell-breaking and feeding device 11. At the same time, the display module 15 displays the operating condition of the electrolytic cell in real time. Information is provided so that when the cell control system malfunctions, the emergency power supply module 13 can supply power to the emergency shell-breaking and feeding system of the aluminum electrolytic cell. Through online data detection and intelligent algorithms, feeding control commands are generated to drive the electrolytic cell execution mechanism to perform single-point uniform feeding of the electrolytic cell, ensuring the stable operation of the electrolytic cell. This quickly solves the problem of manual shell-breaking and feeding when the original cell control system is out of control, such as major maintenance power outages, power supply system failures, regional cell control machine lightning strikes, and internal faults of the cell control machine. It achieves uniform control of the alumina concentration in the electrolytic cell under abnormal cell control conditions, maintaining the material balance and stability of the electrolytic cell.
