Description

Technical Field

[0001] The present application relates to the technical field of hot-dip galvanized strip production, and in particular to a method for treating zinc ash pump jamming in a hot-dip galvanizing production line and related equipment. Background Art

[0002] Hot-dip galvanizing is a widely used anti-corrosion technology in automotive sheet metal, steel structures, and other fields. The formation of zinc ash and slag is an unavoidable problem during the hot-dip galvanizing process. Zinc ash and slag are formed due to surface oxidation of the zinc bath, floating on the surface and in the bath. To maintain the purity of the bath and the quality of the coating, this ash and slag must be regularly cleaned. Ash pumps play a key role in this process, pumping ash from the surface of the bath and the overflow tank. However, ash pump obstruction is a common problem in hot-dip galvanizing production.

[0003] A blocked zinc ash pump can prevent timely removal of zinc ash from the surface of the zinc bath, increasing the zinc ash content in the bath and preventing the overflow trough from overflowing, leading to product defects and degradation, increasing production costs. Furthermore, impurities and unreacted oxides in the zinc ash can adhere to the coating, degrading it and potentially causing plating leaks, impacting coating quality. In severe cases, this can even cause the hot-dip galvanizing line to shut down, significantly impacting production efficiency.

[0004] Therefore, how to clear the zinc ash and zinc slag deposits in the zinc ash pump and effectively avoid the problem of zinc ash pump blocking has become a technical problem that needs to be solved urgently. Summary of the Invention

[0041] See also Figure 1 , which is a schematic flow chart of a method for treating a jammed zinc ash pump in a hot-dip galvanizing production line according to an embodiment of the present application, which may specifically include:

[0042] S110. Blow nitrogen into the zinc ash pump based on the jam signal. The jam signal is used to represent a signal sent by the zinc ash pump when a jam occurs.

[0043] For example, when the zinc ash pump becomes stuck, a jam signal is generated. Upon receiving the jam signal, the control system triggers the nitrogen supply device to deliver nitrogen to the zinc ash pump. In actual hot-dip galvanizing production, the zinc ash and slag are easily deposited inside the pump body during the extraction process of the zinc slag from the surface of the zinc liquid, causing a jam. In this case, a jam signal is generated, and the nitrogen purge process is initiated.

[0044] S120. Zinc ash and zinc slag attached to the inner wall of the zinc ash pump are removed by nitrogen, and the operating status of the zinc ash pump is monitored in real time.

[0045] For example, nitrogen creates a high-speed airflow inside the zinc ash pump, using the impact of the airflow to blow off zinc ash and zinc slag adhering to the inner walls of the zinc ash pump and discharge it through the zinc ash pump outlet. Simultaneously, throughout the purge process, the zinc ash pump's operating status is continuously monitored, such as pump speed, motor current, and other parameters, to determine the cleaning effect and the zinc ash pump's operating condition. Furthermore, the nitrogen gas acts as a cooling agent, lowering the zinc ash pump's operating temperature and further reducing zinc ash adhesion.

[0046] S130. Adjust the flow rate and pressure of the nitrogen gas based on the operating status of the zinc ash pump and a preset threshold value until the nitrogen gas removal effect reaches a preset target, and then release the blocked state of the zinc ash pump.

[0047] For example, the preset thresholds are flow and pressure standards set in advance based on the ash pump's structure, operating environment, and other factors. The real-time monitored operating status of the ash pump is compared with the preset thresholds. If the clearing effect is inadequate, the nitrogen flow and pressure are adjusted. When the ash pump resumes normal operation and reaches the preset normal operating state target (e.g., the motor shaft can rotate and the ash pump resumes normal operation), the jam is considered resolved.

[0048] In some examples, nitrogen is used to remove zinc ash and zinc slag adhering to the inner wall of the zinc ash pump, including:

[0049] Based on the axial structure of the zinc ash pump, the nitrogen is controlled to be blown in from the inlet and outlet of the zinc ash pump at the same time;

[0050] Multiple nitrogen nozzles are set at the inlet and outlet ends to form counter-flow of nitrogen gas along the rotation direction of the impeller of the zinc ash pump;

[0051] Removal of zinc ash and zinc slag based on counter-flow airflow.

[0052] For example, considering the axial structure of the zinc ash pump, blowing nitrogen from both the inlet and outlet allows the nitrogen to more fully cover the interior of the pump, improving the purge effect. The axial structure of different zinc ash pump models may vary, but the overall goal is to ensure that the nitrogen is fully effective in the areas where zinc ash and zinc slag are attached.

[0053] Multiple nitrogen nozzles at the inlet and outlet allow nitrogen to enter the zinc ash pump in a more dispersed, uniform, and directional manner. This counterflow of nitrogen along the impeller's rotation direction enhances the impact and disturbance on the zinc ash and zinc slag, effectively stripping them from the pump's inner wall.

[0054] The strong impact force and turbulence generated by the counter-flow can destroy the adhesion between the zinc ash and zinc slag and the inner wall of the zinc ash pump body, so that the zinc ash and zinc slag are separated from the inner wall and discharged through the zinc ash pump outlet along with the air flow, thereby achieving the purpose of removing the zinc ash and zinc slag.

[0055] In some examples, the process of removing zinc ash and zinc slag attached to the inner wall of the zinc ash pump by nitrogen gas further includes:

[0056] The zinc ash pump is controlled to operate intermittently at a preset speed; wherein the preset speed is less than or equal to 180 revolutions per minute, and the interval period of the intermittent operation is dynamically adjusted based on the degree of zinc ash deposition.

[0057] For example, during the nitrogen purge process, the zinc ash pump is intermittently operated at a preset speed of less than or equal to 180 r / min. Intermittent operation allows the zinc ash and zinc slag inside the pump body to be purged with nitrogen at different motion states, preventing some zinc ash and zinc slag from being difficult to remove due to the pump body being continuously stationary.

[0058] The preset speed limit is less than or equal to 180r / min to prevent excessive speed from adversely affecting the pump body and nitrogen purge efficiency. The interval between intermittent operations is dynamically adjusted based on the degree of zinc ash deposition. If zinc ash deposition is severe, the interval can be appropriately shortened to increase the frequency of pump movement and improve removal efficiency. If zinc ash deposition is light, the interval can be appropriately extended.

[0059] In some examples, the flow rate and pressure of nitrogen are adjusted based on the operating status of the zinc ash pump and a preset threshold, including:

[0060] Determine the preset threshold value based on the size of the zinc ash pump and the degree of zinc ash deposition;

[0061] Based on the nitrogen scavenging effect and the preset threshold, the nitrogen flow and pressure are adjusted.

[0062] For example, different zinc ash pump sizes, internal space dimensions, and flow path structures vary, requiring varying nitrogen flow rates and pressures. Furthermore, the more severe the zinc ash deposits, the higher the flow rate and pressure required for effective removal. Therefore, the preset flow rate and pressure thresholds are determined by comprehensively considering the zinc ash pump size and the severity of the zinc ash deposits.

[0063] During the actual purge process, the observed nitrogen purge effect is compared with the preset threshold. If the purge effect is not ideal, it means that the current flow rate and pressure may not meet the requirements. Adjustments are needed until the purge effect is achieved and the zinc ash pump blockage problem is resolved.

[0064] In some examples, the method for treating a zinc ash pump jam in a hot-dip galvanizing production line further includes:

[0065] Restart the zinc ash pump after the blocking state of the zinc ash pump is released;

[0066] Control the zinc ash pump to operate within the preset speed range and gradually increase it to the target operating speed.

[0067] For example, after nitrogen purging and related adjustments, the zinc ash pump resumes normal operation, the blocking state is released, and after confirming that the motor shaft can rotate, the production personnel restart the zinc ash pump on the local operation screen on the zinc pot drive side to put it into operation again.

[0068] After restarting, first run the zinc ash pump within the preset speed range (e.g., not less than 100r / min). This preset range is to allow the zinc ash pump body to adapt and avoid damage to the zinc ash pump body caused by sudden high-speed operation. Then, as the zinc ash pump body stabilizes, gradually increase the speed to the target operating speed so that the zinc ash pump can complete the task of extracting zinc ash and zinc slag normally and efficiently.

[0069] In some examples, after the stuck state of the zinc ash pump is released, the method further includes:

[0070] Preventive nitrogen backflushing is performed on the slag discharge ports on both sides of the zinc ash pump according to a preset period; wherein the preset period is greater than or equal to 10 minutes.

[0071] For example, after the zinc ash pump blockage issue is resolved, nitrogen backflushing is performed on both sides of the zinc ash pump's slag outlets at a preset interval of 10 minutes or longer. The slag outlets are prone to zinc ash and slag accumulation, and regular backflushing can promptly remove accumulated zinc ash and slag, preventing further accumulation and causing blockage.

[0072] In some examples, preventative nitrogen backflushing includes:

[0073] The nitrogen pressure is controlled within the preset threshold, and the slag discharge ports on both sides of the zinc ash pump are backflushed according to the preset cycle until the zinc ash flow rate at the slag discharge ports on both sides returns to the target range.

[0074] For example, during preventive nitrogen backflushing, the nitrogen pressure should be controlled within a preset threshold (e.g., 2 bar) to prevent excessive or insufficient pressure from affecting the backflushing effect. Backflushing the slag outlet continuously at a preset interval, and the effectiveness of the backflushing is determined by observing the zinc ash flow rate at the slag outlet. When the zinc ash flow rate returns to the target range, it indicates that the zinc ash accumulation at the slag outlet is effectively controlled and the backflushing has achieved the desired effect.

[0075] In summary, the present application provides a method for treating the blockage of the zinc ash pump in the hot-dip galvanizing production line. The zinc ash and zinc slag deposits in the zinc ash pump are removed through the purging effect of nitrogen, thereby effectively avoiding the blockage problem of the zinc ash pump, improving the quality of the strip coating, and improving the guarantee for the normal production of the subsequent production line.

[0076] The technical solution of this application is further described in detail below through specific embodiments.

[0077] In the process of handling the related operations of the zinc ash pump jam in the hot-dip galvanizing production line, when the zinc ash pump is in the specific maintenance and starting stage during the galvanizing annealing roller cycle, the zinc ash pump is controlled to run at a preset speed of no more than 180r / min.

[0078] From the 6th day to the end of the galvanizing annealing roller cycle, the operator uses the transition roll or slag scoop roll on the production line to perform preventive nitrogen backflushing on the slag discharge ports on both sides of the zinc ash pump according to the preset cycle (each cycle is greater than or equal to 10 minutes). The nitrogen pressure is controlled within the preset threshold (here is 2 bar).

[0079] If the zinc ash pump becomes stuck, nitrogen is blown into the pump based on the jam signal to backflush the slag outlet. After 15 minutes, backflush is stopped and the operator attempts to manipulate the motor shaft using a tool (such as a pipe wrench or socket) (this can be considered a manual intervention test of the zinc ash pump's operating status). If the motor shaft cannot be rotated, the operator continues to backflush with nitrogen. Repeat this process of stopping backflush and rotating the motor shaft every 15 minutes until the motor shaft can rotate, indicating that the zinc ash pump's operating status has improved.

[0080] If the motor shaft still cannot be rotated after stopping backflush and rotating the motor shaft several times, the zinc ash pump can be further processed, such as removing the four fixing bolts of the zinc ash pump, raising the zinc ash pump with a chain, and then trying to rotate the motor shaft with a pipe wrench again. When the motor shaft can rotate, lower the zinc ash pump and install it again to restore it to the normal installation state in preparation for subsequent restart.

[0081] When the motor shaft can rotate, it indicates that the jam state of the zinc ash pump has been released. At this time, the operator restarts the zinc ash pump on the relevant operation interface, controls the zinc ash pump to operate within the preset speed range (not less than 100r / min, and the speed can be adjusted higher), and gradually increases it to the target working speed.

[0082] It should be noted that the above embodiments are only the best examples and are not intended to limit the implementation of the present application.

[0083] Furthermore, the present application also proposes a system for treating the blockage of zinc ash pump in hot-dip galvanizing production line, which is applied to any of the above embodiments of the method for treating the blockage of zinc ash pump in hot-dip galvanizing production line, specifically as follows: Figure 2 FIG. 1 is a functional module diagram of a system for treating zinc ash pump jamming in a hot-dip galvanizing production line proposed in this application, including:

[0084] A signal response module 21 is configured to blow nitrogen into the zinc ash pump based on the jam signal; wherein the jam signal is used to indicate a signal emitted by the zinc ash pump when a jam occurs;

[0085] The nitrogen removal module 22 is used to remove zinc ash and zinc slag attached to the inner wall of the zinc ash pump by nitrogen and monitor the operating status of the zinc ash pump in real time;

[0086] The jam releasing module 23 is used to adjust the flow rate and pressure of nitrogen based on the operating state of the zinc ash pump and a preset threshold value until the nitrogen removal effect reaches a preset target, and then release the jam state of the zinc ash pump.

[0087] For example, the signal response module 21 is responsible for receiving a jam signal from the zinc ash pump. Upon receiving the jam signal, it triggers the nitrogen supply device to deliver nitrogen into the zinc ash pump, initiating the entire process. The nitrogen removal module 22 controls the nitrogen to form a high-speed flow inside the zinc ash pump, removing zinc ash and zinc slag. Simultaneously, it monitors the zinc ash pump's operating status in real time, collecting relevant data to inform subsequent adjustments. The jam removal module 23 compares and analyzes the zinc ash pump's operating status, as monitored by the nitrogen removal module 22, with a preset threshold. If the cleaning effect does not meet the preset target, the nitrogen flow and pressure are adjusted until the zinc ash pump resumes normal operation and the jam is resolved.

[0088] In one specific embodiment, first connect the nitrogen supply device to the zinc ash pump, ensuring a tight connection to prevent nitrogen leakage. Select the appropriate connection method and connector based on the size of the zinc ash pump and the type of nitrogen supply device. Then, open the valve of the nitrogen supply device and adjust the nitrogen flow and pressure to achieve the appropriate purge effect. Generally, the nitrogen flow and pressure should be determined based on the structure of the zinc ash pump and the zinc ash deposition conditions. A pressure of 2 kg is generally used initially. Excessive pressure can cause zinc slag to backflow into the overflow lip of the furnace nose, causing slag to stick to the lip and hinder subsequent production. After ensuring that all preparations are in place, initiate the nitrogen purge procedure. Nitrogen will enter the zinc ash pump through the inlet and outlet of the zinc ash pump, forming a high-speed airflow that removes zinc ash and slag adhering to the zinc ash pump body and the inner wall of the pipeline. During the purge process, closely monitor the operation of the zinc ash pump and the nitrogen purge effect. If the purge effect is poor, adjust the nitrogen flow and pressure appropriately, or change the purge angle and position. After the nitrogen purge is completed, the zinc ash and zinc slag remaining on the inlet, outlet and inner wall of the zinc ash pump should be cleaned in time. Special cleaning tools or equipment can be used to clean them to ensure that the zinc ash pump can resume normal operation.
