Description

Technical Field

[0001] This invention relates to the field of electrolytic cell monitoring technology, and in particular to an electrolytic cell deformation monitoring and compensation device and its usage method. Background Technology

[0002] In electrolysis industrial production, the electrolytic cell is the core equipment for realizing electrochemical reactions, and its structural stability directly affects production efficiency and safety. However, under long-term high temperature, high pressure, and gravity, horizontally placed electrolytic cells are prone to deformation. Irregular deformation of the cell not only alters the internal electrode spacing, affecting the uniformity of the electrolytic reaction, but may also cause electrolyte leakage, increasing equipment maintenance costs and safety risks.

[0003] Meanwhile, the sealing performance of the electrolytic cell depends on the gasket between the cell body and the cover plate. Existing gaskets are made of rubber, which is prone to localized compression, stretching, or even detachment due to cell deformation. Gasket detachment leads to electrolyte leakage, exacerbates equipment corrosion, wastes energy, and in severe cases, requires shutdown for gasket replacement, disrupting continuous production.

[0004] Currently, monitoring of electrolytic cell deformation relies heavily on periodic manual measurements, which is not only cumbersome and inaccurate but also fails to provide real-time updates on deformation dynamics. Furthermore, there is a lack of effective adjustment methods for deformation compensation, often requiring major overhauls only after severe deformation has occurred. Regarding the issue of gasket detachment, existing technologies primarily address it by increasing gasket thickness or improving installation tightness, but these methods fail to fundamentally solve the problem of uneven gasket stress caused by cell deformation, making it difficult to completely eliminate the risk of detachment. Summary of the Invention

[0007] Preferably, the displacement monitoring device includes a T-shaped steel plate horizontally fixed above the electrolytic cell, and the infrared rangefinder is vertically fixed at the bottom of the T-shaped steel plate.

[0016] Preferably, a mounting box is fixedly provided on the bottom edge of the movable base, and rollers are rotatably arranged on the bottom of the mounting box. A drive motor for driving the rollers to rotate is provided inside the mounting box, and the movable controller controls and connects to the drive motor.

[0017] A method for using an electrolytic cell deformation monitoring and compensation device includes the following steps: S1. Device initialization: Complete the installation, positioning, and signal connection of the electrolytic cell and monitoring and compensation components, and reset the compensation structure to its initial state; S2. Deformation monitoring: The position data of the electrolytic cell plates are collected by a displacement monitoring device to determine the deformation area and record relevant parameters. S3. Compensation Positioning: The moving seat of the drive compensation device slides along the axial direction of the electrolytic cell, so that the compensation structure is aligned with the deformation area; S4. Precise compensation: The compensation structure is adjusted to act on the deformed area of ​​the electrolytic cell, and a corresponding force is applied to correct the deformation. S5. Feedback Adjustment: Continuously monitor the state of the deformed area and fine-tune the compensation parameters based on the feedback data until the deformation is corrected. S6. Cyclic maintenance: Periodically monitor the condition of the electrolytic cell, dynamically compensate for new deformation areas, and regularly maintain the device components. Preferably, the device initialization in step S1 includes: horizontally erecting the electrolytic cell via support piers; welding and fixing the two ends of the T-shaped steel plate to the top of the end pressure plates at both ends of the electrolytic cell; ensuring that the infrared rangefinders are equidistantly distributed along the axial direction of the electrolytic cell and that the detection end is vertically aligned with the top of the electrode plate; fixing the base plate directly below the electrolytic cell; installing the moving seat in a slot to fit the track plate; ensuring the rollers are in contact with the ground; connecting the end of the rope displacement sensor to the end of the moving seat; completing the signal connection between the infrared rangefinder, encoder, and moving controller; resetting the hydraulic cylinder to the initial position; and positioning the support rod at the reserved gap at the bottom of the electrolytic cell. Preferably, the deformation monitoring in step S2 includes: starting the infrared rangefinder, labeling each infrared rangefinder, continuously collecting vertical distance data between the top of the electrode plate and the bottom of the T-shaped steel plate at each detection point and transmitting it to the control terminal; the control terminal presets a standard distance threshold under normal electrode plate conditions, and when the data of a certain detection point deviates from the threshold by more than 0.5mm, it is determined that deformation has occurred in the corresponding area, and the axial coordinate of the deformation location and the amount of deformation are recorded. The axial coordinate is the axial coordinate corresponding to the label of the infrared rangefinder. Preferably, the compensation positioning in step S3 includes: the control terminal sending a command to the motion controller to drive the drive motor in the mounting box to rotate, causing the roller to rotate and the moving seat to slide along the track plate; through the meshing transmission of the rack and pinion on the side wall of the track plate and the gear in the slot, the encoder collects the displacement data of the moving seat in real time, and the pull rope displacement sensor synchronously assists in calibrating the displacement accuracy until the support rod is precisely aligned with the deformation position recorded in step S2 along the axial direction, and the motion controller controls the drive motor to stop. Preferably, the precise compensation in step S4 includes: the control terminal sends a telescopic command to the hydraulic cylinder according to the deformation amount recorded in step S2, and the moving end of the hydraulic cylinder drives the reset component to rise vertically along the guide rod, so that the top of the support rod is tightly attached to the deformation area at the bottom of the electrolytic cell; The hydraulic cylinder continuously pressurizes to the preset pressure value, and applies an upward supporting force to the deformed area through the support rod until the infrared rangefinder detection data returns to the standard threshold.

[0018] Preferably, the feedback adjustment in step S5 includes: after the compensation operation is completed, the infrared rangefinder continuously monitors the deformed area for 5-10 minutes. If the monitoring data is stably maintained within the standard threshold range, the hydraulic cylinder maintains the current extension and retraction amount, and the moving seat maintains the positioning state. If the monitoring data still deviates from the standard threshold, repeat steps S3 and S4, and adjust the support pressure by fine-tuning the axial positioning of the moving seat or adjusting the hydraulic cylinder until the deformed area is completely restored to the normal state. Preferably, the cyclic maintenance in step S6 includes: the device is continuously in operation, and the infrared rangefinder completes a full scan of the electrolytic cell every 10-30 minutes to capture newly appearing deformed areas in real time; The moving seat moves back and forth along the track plate according to the scanning results, and performs the positioning, compensation and adjustment steps S3-S5 in sequence for the newly deformed area; Every 7-15 days of operation, check the wear of the rollers at the bottom of the moving seat and test the sealing performance of the hydraulic cylinder. Replace worn parts or repair sealing defects in a timely manner to ensure long-term stable operation of the device.

[0019] This invention provides an electrolytic cell deformation monitoring and compensation device and method, which has the following beneficial effects.

[0020] 1. By installing an infrared rangefinder on top of the electrolytic cell, the cell can be monitored in real time with high precision from all directions. After the initial data is entered into the control unit, when the cell deforms, the infrared rangefinder at the corresponding position can promptly feed the data back to the control unit. Combined with the equipment number, the deformation location can be accurately pinpointed. This solves the problems of cumbersome, low-precision, and unreal-time monitoring associated with traditional manual measurement, providing a precise basis for subsequent compensation work.

[0021] 2. The compensation component moves along the guide rail via a movable seat, precisely reaching directly below the deformation location. A hydraulic cylinder then pushes the reset component, using a support rod to perform targeted compensation. The reset component avoids the original tie rod, and the triangular support plate enhances the stability of the support rod. The high-strength steel support rod ensures reliable pushing during the process. This effectively solves the shortcomings of traditional compensation methods, such as lack of specificity and the need for major repairs only after severe deformation, significantly improving the efficiency and effectiveness of deformation repair.

[0022] 3. By timely monitoring and compensating for tank deformation, localized compression and stretching of the gaskets caused by irregular tank deformation are avoided, fundamentally alleviating the problem of uneven gasket stress and reducing the probability of gasket detachment. This not only reduces equipment corrosion and energy waste caused by electrolyte leakage, but also reduces the frequency of downtime due to gasket replacement, ensuring production continuity.

[0024] Figure 2 This is a schematic diagram of the compensation component in an embodiment of the present invention.

[0026] like Figure 1 and Figure 2 As shown, the present invention provides an electrolytic cell deformation monitoring and compensation device, including an electrolytic cell horizontally arranged by a support pier 1, a displacement monitoring device horizontally fixedly installed on the top of the electrolytic cell, the displacement monitoring device including an infrared rangefinder 7 with its detection end facing the top of the electrode plate 3 in the electrolytic cell, the infrared rangefinder 7 being equidistantly arranged along the axial direction of the electrolytic cell, and a compensation device provided at the bottom of the electrolytic cell, the compensation device including a movable seat slidably arranged along the axial direction of the electrolytic cell and a compensation structure vertically slidably arranged on the top of the movable seat.

[0027] The electrolytic cell body includes two support blocks 1, an end pressure plate 2 vertically fixed on the support blocks 1, and a tension bolt assembly 4 connecting the two end pressure plates 2. The electrode plates arranged at equal intervals are tensioned by the tension bolt assembly 4.

[0028] During operation, each infrared rangefinder 7 is numbered and its measurement distance is initialized. When the electrode plate 3 descends due to gravity and pressure, the infrared rangefinder 7 sends the measured data to the control center. The control center compares the data and can then determine that the electrode plate 3 at the measured position has descended. The data is then transmitted to the motion controller, which controls the drive motor to rotate the roller 12. The roller 12 moves the moving seat 10 to the set position. Then, the compensation structure pushes the electrode plate 3 to compensate for the deformation.

[0029] like Figure 1 As shown. The displacement monitoring device includes a T-shaped steel plate 5 horizontally fixed above the electrolytic cell, and an infrared rangefinder 7 vertically fixed to the bottom of the T-shaped steel plate 5. The infrared rangefinder 7 is installed vertically downwards using the T-shaped steel plate 5, and locked in place by mounting pieces 6. The T-shaped steel plate 5 prevents bending in the middle during long-term operation, ensuring that the installation position of the infrared rangefinder 7 does not shift, thereby maintaining the accuracy of the infrared rangefinder 7.

[0030] like Figure 1 As shown, to ensure the stability of the T-shaped steel plate 5 during installation, both ends of the T-shaped steel plate 5 are welded to the top of the end pressure plates 2 at both ends of the electrolytic cell.

[0031] like Figure 1 and Figure 2As shown. The compensation device includes a base plate 8 arranged directly below the electrolytic cell and a movable seat 10 slidably arranged on the base plate 8. The compensation structure includes a hydraulic cylinder 13 mounted on the movable seat 10 and a tubular support rod 16 fixed to the movable end of the hydraulic cylinder 13. The support rod 16 is arranged horizontally. When pushing the electrode plate 3, the movable end of the hydraulic cylinder 13 is controlled to extend upward, thereby driving the support rod 16 to move upward. The support rod 16 pushes the electrode plate 3 upward. During the pushing process, the infrared rangefinder 7 continues to monitor and continuously feed back the distance of the electrode plate 3. After the electrode plate 3 is reset, the hydraulic cylinder 13 is controlled to retract, and the movable seat 10 is reset.

[0032] like Figure 1 and Figure 2 As shown. A reset member 14 is fixedly connected to the movable end of the hydraulic cylinder 13. Vertical plates are fixedly connected to both ends of the top of the reset member 14, and the support rod 16 is connected to the top of the vertical plates. The reset member 14 includes a lifting plate at the bottom, which is directly connected to the movable end of the hydraulic cylinder 13. The vertical plates are installed through the lifting plate, and finally the support rod 16 is installed through the vertical plates. The vertical plates are arranged on both sides of the lifting plate to avoid interference between the vertical plates and the electrode plate 3.

[0033] like Figure 2 As shown, to ensure sufficient structural strength, the vertical plates are equidistantly distributed along the axial direction of the support rod 16, and each vertical plate is a triangular plate.

[0034] like Figure 2 As shown, to ensure the stability of the movement of the support rod 16, a guide rod 15 is vertically fixed to the top of the movable seat 10, and the guide rod 15 vertically passes through the reset member 14.

[0035] like Figure 1 and Figure 2 As shown, to ensure the stability of the movement of the movable seat 10, a track plate 9 is vertically fixed to the top of the base plate 8, and a slot adapted to the track plate 9 is provided at the bottom of the movable seat 10.

[0036] As a preferred embodiment of the present invention, a displacement detection feedback structure for the movable seat 10 is provided to ensure that the movable seat 10 moves accurately to the deformation point of the electrolytic cell, thereby achieving precise compensation of the electrolytic cell. A rack is horizontally arranged on the side wall of the track plate 9, and a gear meshing with the rack is rotatably arranged in the slot. An encoder is connected to the mounting shaft of the gear, and the encoder signal is connected to the movement controller of the movable seat 10. During the movement of the movable seat 10 along the track plate 9, the rack causes the gear inside the movable seat 10 to rotate. The gear, through its mounting shaft, drives the output end of the encoder to rotate, thereby transmitting the displacement of the movable seat 10 to the movement controller. After calculation, the position of the movable seat 10 on the track plate 9 can be determined.

[0037] As a preferred embodiment of the present invention, another displacement detection feedback structure for the movable seat 10 is provided. A pull-cord displacement sensor is connected to one end of the base plate 8, and the rope end of the pull-cord displacement sensor is connected to the end of the movable seat 10. The pull-cord displacement sensor signal is connected to the movement controller of the movable seat 10. The winding structure inside the pull-cord displacement sensor ensures the tension of the pull-cord. The movement of the movable seat 10 corresponds to the unwinding or winding of the pull-cord, thereby enabling feedback of the displacement of the movable seat 10 to the movement controller.

[0038] like Figure 2 As shown. A mounting box 11 is fixedly installed on the bottom edge of the movable base 10. Rollers 12 are rotatably arranged on the bottom of the mounting box 11. A drive motor that drives the rollers 12 to rotate is installed inside the mounting box 11. The motion controller controls and connects to the drive motor. The motion controller, combining the target position coordinates sent by the control center and the real-time coordinates given by the displacement feedback structure of the movable base 10, continuously adjusts the rotation of the drive motor, enabling the movable base 10 to move accurately to the set coordinates.

[0039] A method for using an electrolytic cell deformation monitoring and compensation device includes the following steps: S1. Device Initialization: The electrolytic cell is horizontally erected using support pier 1. The two ends of the T-shaped steel plate 5 are welded and fixed to the top of the end pressure plates 2 at both ends of the electrolytic cell, ensuring that the infrared rangefinders 7 are evenly distributed along the axial direction of the electrolytic cell and that the detection end is vertically aligned with the top of the electrode plate 3. The base plate 8 is fixed directly below the electrolytic cell. The moving seat 10 is fitted and installed with the track plate 9 through a slot. The roller 12 is in contact with the ground. The end of the rope displacement sensor is connected to the end of the moving seat 10, completing the signal connection between the infrared rangefinder 7, the encoder, the rope displacement sensor and the moving controller. The hydraulic cylinder 13 is reset to the initial position, and the support rod 16 is located at the reserved gap at the bottom of the electrolytic cell. S2. Deformation Monitoring: Start the infrared rangefinder 7, number the infrared rangefinder 7, and confirm the axial displacement coordinate of the infrared rangefinder 7. Continuously collect the vertical distance data between the top of the electrode plate 3 and the bottom of the T-shaped steel plate 5 at each detection point, and transmit the data to the control terminal. The control terminal presets the standard distance threshold under normal conditions of the electrode plate 3. When the data of a certain detection point deviates from the threshold by more than 0.5mm, it is determined that the corresponding area has deformed, and the deformation location and deformation amount are recorded. S3, Compensation Positioning: The control terminal sends a command to the motion controller to drive the drive motor in the mounting box 11 to rotate the roller 12, causing the moving seat 10 to slide along the track plate 9; through the meshing transmission of the rack and pinion on the side wall of the track plate 9 and the gear in the slot, the encoder collects the displacement data of the moving seat 10 in real time, and the pull rope displacement sensor synchronously assists in calibration until the support rod 16 is aligned axially with the deformation position recorded in S2, and the motion controller controls the drive motor to stop, completing the compensation positioning; S4. Precise Compensation: Based on the deformation recorded in S2, the control terminal sends a telescopic command to the hydraulic cylinder 13. The movable end of the hydraulic cylinder 13 drives the reset component 14 to rise vertically along the guide rod 15, so that the top of the support rod 16 is in contact with the deformation area at the bottom of the electrolytic cell. If the electrode plate 3 has a negative deviation due to sinking, the hydraulic cylinder 13 continues to increase the pressure to the preset pressure, which is set to 5-15MPa according to the weight of the electrolytic cell and the amount of deformation. The support rod 16 applies an upward supporting force to the deformation area until the data detected by the infrared rangefinder 7 returns to the standard threshold. If a local protrusion with a positive deviation occurs, the hydraulic cylinder 13 drives the support rod 16 to rise to fit the bottom of the protrusion. The elastic buffering characteristics of the reset component 14 limit further deformation of the protrusion, and the data changes are monitored simultaneously. S5. Feedback Adjustment: After compensation is completed, the infrared rangefinder 7 continuously monitors the data of the deformed area for 5-10 minutes. If the data is stable within the standard threshold, the hydraulic cylinder 13 maintains the current extension and retraction amount, and the moving seat 10 remains in the positioning state. If the data still has deviation, repeat steps S3-S4, and fine-tune the positioning by the moving seat 10 or adjust the support force by the hydraulic cylinder 13 until the deformed area is completely restored to the normal state. S6. Cyclic Maintenance: The device operates continuously. The infrared rangefinder 7 completes a full-area scan every 10-30 minutes. The moving seat 10 moves back and forth on the track plate 9 according to the monitoring results. The newly appearing deformed areas are compensated according to steps S3-S5. The wear of the roller 12 and the sealing performance of the hydraulic cylinder 13 are checked regularly to ensure the long-term stable operation of the device.
