Description

Technical Field

[0001] This invention relates to the field of hot-dip galvanizing technology, specifically to a galvanizing re-blowing device and its usage method. Background Technology

[0002] In the hot-dip galvanizing production of steel products, excessive zinc liquid adheres to the surface of the galvanized workpiece. If this excess zinc is not removed promptly and evenly, it can lead to uneven zinc layer thickness, surface defects such as zinc nodules and porosity, severely affecting the corrosion resistance and appearance quality of the workpiece. Therefore, the reblowing process after galvanizing is a key step in the hot-dip galvanizing production line. Its core is to use airflow to blow away excess zinc liquid from the workpiece surface, allowing the zinc layer to solidify quickly and form a uniform and smooth coating.

[0003] The back-blowing devices currently used in hot-dip galvanizing production lines generally suffer from poor adaptability. The airflow channels of existing back-blowing devices are mostly fixed structures, unable to be flexibly adjusted according to workpiece specifications. When changing workpiece types, the entire back-blowing device often needs to be replaced, increasing equipment investment costs and extending production line downtime, severely impacting production efficiency. Furthermore, the splicing parts of existing devices mostly use traditional fixing methods such as bolt fastening, making disassembly and assembly cumbersome and further exacerbating the inconvenience of changeover adjustments.

[0004] In the reblowing process, airflow pressure and temperature are key factors affecting the reblowing effect. However, existing reblowing devices lack effective real-time monitoring methods and cannot accurately grasp pressure and temperature changes within the airflow channel. When production line conditions fluctuate, such as changes in zinc liquid temperature or adjustments to workpiece conveying speed, the airflow parameters cannot be adjusted in time, easily leading to problems such as workpiece deformation due to excessive pressure or zinc layer residue due to insufficient pressure. Especially when processing thin-walled pipes or complex structural workpieces, unstable airflow parameters can significantly increase the product defect rate.

[0005] Existing equipment mostly relies on manual adjustment of airflow parameters, resulting in low adjustment accuracy and slow response speed. This makes it impossible to achieve automated closed-loop control of process parameters, failing to meet the demands of modern production lines for precise and intelligent manufacturing. Therefore, we need to propose a galvanizing re-blowing device and its usage method. Summary of the Invention

[0030] A method for using a galvanizing re-blowing device includes the following steps:

[0031] S1. Installation and Positioning: By adsorbing and engaging the magnetic ring of the positioning component with the magnetic ring of the mounting and bearing component, the semi-circular ring structure of the first and second wind molds is aligned with the mounting holes on the bracket; precise positioning is achieved by the sliding engagement of the third limiting block and the third limiting groove; the bracket is fixed to the key work position of the production line by the bolts on the mounting plate, and the overall installation of the device is completed.

[0032] S2. Splicing and locking: Insert the first limiting block of the first wind model into the first limiting groove of the second wind model to achieve the initial splicing of the wind model components; by symmetrically engaging the two clamp components of the fixing component in the connecting groove, rotate the lever to make the fixing block embed into the arc groove of the first connecting block to complete the mechanical locking of the splicing part of the wind model.

[0033] S3. Parameter detection and adjustment: After the device is started, the miniature pressure sensor and miniature temperature sensor of the sensing component collect the airflow pressure and temperature data at each air hole in real time; the PLC controller receives and analyzes the detection signal, and when an abnormal pressure or temperature is detected in a certain area, it drives the electric push rod of the corresponding air hole, which drives the adjustment plate to move through the transmission mechanism in the protective box, so that the overlapping area of ​​the adjustment through hole and the air hole changes, and the air outlet area is dynamically adjusted.

[0034] S4. Maintenance and Cleaning: Regularly check the integrity of the superhydrophobic and oleophobic nano-coating on the inner wall of the air vents.

[0035] S5. Fault Diagnosis and Emergency Handling: When the sensing components detect a continuous abnormal signal, the PLC controller triggers an alarm mechanism and automatically shuts down the electric push rod in the corresponding area to prevent equipment damage; maintenance personnel can quickly locate the faulty components through RFID tags for targeted repair or replacement.

[0036] Compared with the prior art, the beneficial effects of the present invention are:

[0037] 1. This invention effectively solves the problems of fixed airflow channels and poor adaptability of existing return blowing devices by using a detachable splicing design of the wind mold components and a locking and fixing function of the snap-fit ​​fixing components. The airflow channel structure can be flexibly adjusted according to different specifications of workpieces without the need to replace the entire device, which significantly reduces the equipment investment cost. At the same time, compared with traditional bolt fastening, the snap-fit ​​fixing method greatly simplifies the disassembly and assembly process of the splicing parts, shortens the downtime of production line changeover and adjustment, and improves production efficiency.

[0038] 2. This invention uses sensing components to detect airflow pressure and temperature parameters in real time, and combines this with control components to automatically control the air outlet adjustment components, thus constructing a complete closed-loop parameter adjustment system. This effectively solves the problems of existing technologies, such as the lack of real-time detection methods, reliance on manual airflow parameter adjustment, low accuracy, and slow response. It can adjust the air outlet area in a timely and accurate manner according to fluctuations in production line conditions, ensuring that airflow parameters are stable and adapted to the workpiece processing requirements. This reduces defects such as workpiece deformation and zinc layer residue caused by improper parameters, and especially improves the product qualification rate under special working conditions such as thin-walled pipes and complex structure workpieces, meeting the precision and intelligent production needs of modern production lines.

[0039] 3. This invention achieves precise positioning and detachable connection between the wind mold component and the mounting support component by connecting the positioning component. Combined with the mounting support component's role in supporting the installation of each component and fixing the production line station, it effectively solves the problems of insufficient connection and positioning accuracy, installation offset affecting the uniformity of backblowing, and poor versatility of the support structure in existing devices. It not only ensures the precise alignment of the airflow blowing direction with the workpiece surface and improves the uniformity of backblowing, but also enhances the adaptability of the device to different production line station layouts, further improving the device's versatility and flexibility of use.

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] Example 1:

[0052] Please see Figures 1-9 The present invention provides a technical solution:

[0053] A galvanizing re-blowing device, comprising:

[0054] The wind mold assembly is used to form an airflow channel for galvanized back blowing and to achieve detachable splicing. The wind mold assembly includes a first wind mold 1 and a second wind mold 2. The first wind mold 1 is provided with a first limiting block 3, and the second wind mold 2 is provided with a first limiting groove 4 that is adapted to the first limiting block 3. The first limiting block 3 is engaged in the first limiting groove 4 to achieve splicing and positioning of the first wind mold 1 and the second wind mold 2.

[0055] Both the first wind model 1 and the second wind model 2 have air holes 5 for forming a return airflow. The air holes 5 are arranged in an inclined manner, and the inner wall of the air holes 5 is provided with a superhydrophobic and oleophobic coating, which is a nano-coating.

[0056] The locking and fixing assembly is used to lock and fix the splicing parts of the wind mold assembly. The locking and fixing assembly includes two symmetrically arranged clamp assemblies. Both ends of the first wind mold 1 and the second wind mold 2 are provided with connecting grooves 6 for the clamp assemblies to engage.

[0057] Each clamp assembly includes two arc-shaped rings 7, a first connecting block 8, and a second connecting block 9. The two arc-shaped rings 7 are respectively engaged in the connecting groove 6 at the joint of the first wind mold 1 and the second wind mold 2. The first connecting block 8 and the second connecting block 9 are respectively connected to the ends of the two arc-shaped rings 7, and the other ends of the two arc-shaped rings 7 are hinged.

[0058] The first connecting block 8 is provided with a connector 10, one end of which is provided with an arc groove 11. The second connecting block 9 is rotatably connected to a fixing block 12, and a lever 13 is connected to the fixing block 12.

[0059] The assembly of the wind model components is performed as follows: Align the first limiting block 3 on the first wind model 1 with the first limiting groove 4 on the second wind model 2 and engage them in place for initial positioning. Then, insert the two arc-shaped rings 7 of the engaging and fixing component into the connecting grooves 6 at both ends of the two wind models. Rotate the fixing block 12 on the second connecting block 9, and through the lever 13, engage it with the arc-shaped groove 11 of the connecting piece 10 on the first connecting block 8, completing the locking and fixing of the assembly. Here, the engagement and positioning of the first limiting block 3 and the first limiting groove 4, combined with the locking structure of the clamp component, forms a quick-disassembly and assembly system for the wind model components. This not only simplifies the assembly operation but also ensures the airtightness of the airflow channel, effectively solving the problems of cumbersome assembly and poor sealing leading to airflow leakage in traditional wind model assembly. Simultaneously, the synergistic effect of the engaging and fixing component and the wind model components achieves rapid assembly while avoiding energy loss and reduced back-blowing effect caused by airflow leakage, further enhancing the practicality of the device.

[0060] When shutting down, the airflow input device must be turned off first. After the airflow pressure inside the wind model assembly drops to a safe range, the power to the control assembly should be turned off. During maintenance, the fixing block 12 can be disengaged from the connector 10 by moving the lever 13 of the locking assembly, the clamp assembly can be released, and the first wind model 1 and the second wind model 2 can be separated, making it easier to clean or repair the inner wall of the air hole 5 and the adjustment assembly. If the wind model assembly needs to be replaced, the magnetic ring can be released directly, the wind model assembly can be pulled out along the third limiting groove 24, and then reinstalled and positioned. This process makes full use of the detachable splicing structure of the wind model assembly and the detachable connection characteristics of the connecting positioning assembly, which greatly improves the convenience of maintenance and reduces maintenance costs.

[0061] The sensing component is used to detect the airflow pressure and temperature parameters in the wind turbine component in real time. The sensing component includes a miniature pressure sensor 14 and a miniature temperature sensor 15. The miniature pressure sensor 14 and the miniature temperature sensor 15 are integrated in the vicinity of each air hole 5 to detect the airflow pressure and temperature at the corresponding air hole 5 respectively.

[0062] An air outlet adjustment component is used to adjust the air outlet area of ​​the wind model component according to the detected parameters. The air outlet adjustment component includes an air hole 5 adjustment unit, which is installed on the first wind model 1 and the second wind model 2 in correspondence with the air hole 5.

[0063] Each air hole 5 adjustment unit includes an electric push rod 16 and an adjustment plate 17. The electric push rod 16 is installed on the first wind mold 1 or the second wind mold 2. The output end of the electric push rod 16 is connected to the adjustment plate 17. The adjustment plate 17 is provided with an adjustment through hole 18 for adjusting the air outlet area of ​​the air hole 5.

[0064] The adjusting plate 17 is provided with a second limiting block 19, and the first wind mold 1 and the second wind mold 2 are both provided with a second limiting groove 20 for sliding connection of the second limiting block 19;

[0065] The connection positioning component is used to achieve precise positioning and detachable connection between the wind mold component and the installation support component. The connection positioning component includes a magnetic ring set on the first wind mold 1 and the second wind mold 2 and embedded on a semi-circular ring, and a magnetic ring set on the bracket 21.

[0066] The mounting support assembly is used to provide mounting support for various components of the device and to fix the device to the key work station of the production line. The mounting support assembly includes a bracket 21 and a mounting plate 22. The bracket 21 has mounting holes 23 for the wind mold assembly to be snapped into place. The mounting holes 23 have third limiting grooves 24 on both sides. The third limiting block 25 on the wind mold assembly is slidably connected to the third limiting groove 24.

[0067] The RFID tag is installed on the bracket 21 at a position opposite to the mounting hole 23; the bracket 21 is provided with a mounting plate 22, which is fixedly connected to the key work station of the production line by bolts.

[0068] After assembling the wind turbine components, the connection between the wind turbine components and the mounting support components is performed: the third limiting block 25 on the wind turbine component is aligned with the third limiting grooves 24 on both sides of the mounting hole 23 on the bracket 21 and slid into the designated position. At this time, the magnetic ring on the wind turbine component and the magnetic ring on the bracket 21 are attracted and attached, achieving precise positioning and temporary fixation. After checking the stability, the installation is confirmed to be in place. This operation relies on the cooperative structure of the magnetic ring and magnetic ring of the connecting positioning component being attracted and positioned, and the third limiting block 25 and the third limiting groove 24 being slidably guided, to achieve precise and rapid docking between the wind turbine components and the mounting support components, while also having a detachable feature. Finally, the compatibility of the control components with other components is checked to ensure that the electrical connection between the PLC controller 26 and the electric push rod 16, pressure sensor, and temperature sensor is normal. The mounting plate 22 of the mounting support components is then fixed to the key workstation of the production line with bolts, completing the overall assembly. The mounting support components provide stable support for the entire device, and the RFID tag integrated on its bracket 21 can also realize the identification of the device and full life cycle traceability, effectively solving the problems of chaotic management of multiple devices on the production line and unclear maintenance records.

[0069] The control component is used to receive the detection signals from the sensing component and control the operation of the air outlet regulating component. The control component includes a protective box mounted on the bracket 21 and a PLC controller 26 mounted inside the protective box. The PLC controller 26 is electrically connected to the electric push rod 16, the pressure sensor and the temperature sensor respectively.

[0070] Upon startup, the sensing components immediately begin operation. Miniature pressure sensors 14 and miniature temperature sensors 15, integrated near each air vent 5, collect real-time airflow pressure and temperature parameters at the corresponding air vent 5 and continuously transmit the signals to the PLC controller 26 of the control component. The PLC controller 26 analyzes and processes the received parameters, comparing them with preset standard parameters. This process constitutes a collaborative data transmission and analysis system between the sensing and control components. When the detected parameters deviate from the preset range, the PLC controller 26 automatically sends an adjustment command to the corresponding electric push rod 16. The electric push rod 16 drives the adjustment plate 17 to slide along the second limit groove 20 on the second wind mold 2 and the first wind mold 1. By adjusting the degree of overlap between the adjustment through hole 18 on the adjustment plate 17 and the air vent 5, the airflow area is changed, causing the airflow pressure and temperature to return to the preset range. If the parameters meet the requirements, the current airflow state is maintained for stable operation. Here, the sensing component, control component, and air outlet adjustment component form a closed-loop control system. These three components work together to achieve dynamic balance of airflow parameters, ensuring the stability of the galvanizing back-blowing process and solving the problem of unstable galvanizing quality and low product qualification rate caused by uncontrollable airflow parameters in traditional back-blowing devices. Simultaneously, the synergistic effect of the second limiting block 19 on the adjustment plate 17 and the second limiting groove 20 of the wind mold component ensures the smoothness and precision of the sliding of the adjustment plate 17, further improving the accuracy of the air outlet area adjustment. It is worth noting that the air holes 5 of the wind mold component are arranged at an angle, and the inner wall is coated with a nano-superhydrophobic and oleophobic coating. This structural feature enables the inner wall of the air holes 5 to resist oil stains and adhesion, solving the problem of oil stains and impurities adhering and clogging the air holes 5 during the galvanizing process, leading to poor airflow and reduced back-blowing efficiency, thus ensuring stable airflow output.

[0071] Example 2:

[0072] The difference between Example 2 and Example 1 is that:

[0073] A method for using a galvanizing re-blowing device includes the following steps:

[0074] S1. Installation and Positioning: By adsorbing and engaging the magnetic ring of the positioning component with the magnetic ring of the mounting and bearing component, the semi-circular ring structure of the first wind mold 1 and the second wind mold 2 is aligned with the mounting hole 23 on the bracket 21; precise positioning is achieved by the sliding engagement of the third limiting block 25 and the third limiting groove 24; the bracket 21 is fixed to the key station of the production line by the bolts on the mounting plate 22, and the overall installation of the device is completed.

[0075] S2. Splicing and locking: Insert the first limiting block 3 of the first wind mold 1 into the first limiting groove 4 of the second wind mold 2 to achieve the initial splicing of the wind mold components; by symmetrically engaging the two clamp components of the fixing components in the connecting groove 6, rotate the lever 13 to make the fixing block 12 embed into the arc groove 11 of the first connecting block 8 to complete the mechanical locking of the splicing part of the wind mold.

[0076] S3. Parameter detection and adjustment: After the device is started, the miniature pressure sensor 14 and miniature temperature sensor 15 of the sensing components collect the airflow pressure and temperature data at each air hole 5 in real time; the PLC controller 26 receives the detection signal and analyzes it. When an abnormal pressure or temperature is detected in a certain area, it drives the electric push rod 16 of the corresponding air hole 5, which drives the adjustment plate 17 to move through the transmission mechanism in the protective box, so that the overlapping area of ​​the adjustment through hole 18 and the air hole 5 changes, and the air outlet area is dynamically adjusted.

[0077] S4. Maintenance and Cleaning: Regularly check the integrity of the superhydrophobic and oleophobic nano-coating on the inner wall of the air hole 5. If the coating is found to be worn, surface repair is required. The wind turbine assembly can be disassembled and maintained by removing the clamp assembly. Clean the residual impurities inside the air hole 5 to ensure that the airflow channel is unobstructed.

[0078] S5. Fault Diagnosis and Emergency Handling: When the sensing component detects a continuous abnormal signal, the PLC controller 26 triggers the alarm mechanism and automatically shuts down the electric push rod 16 in the corresponding area to prevent equipment damage; maintenance personnel can quickly locate the faulty component through the RFID tag and carry out targeted repair or replacement.

Splicing and locking: Insert the first limiting block (3) of the first wind mold (1) into the first limiting groove (4) of the second wind mold (2) to achieve the initial splicing of the wind mold components; by symmetrically engaging the two clamp components of the fixing components in the connecting groove (6), rotate the lever (13) to make the fixing block (12) embed into the arc groove (11) of the first connecting block (8) to complete the mechanical locking of the splicing part of the wind mold; S3. Parameter detection and adjustment: After the device is started, the miniature pressure sensor (14) and miniature temperature sensor (15) of the sensing component collect the airflow pressure and temperature data at each air hole (5) in real time; the PLC controller (26) receives the detection signal and analyzes it. When an abnormal pressure or temperature is detected in a certain area, the electric push rod (16) of the corresponding air hole (5) is driven to move the adjustment plate (17) through the transmission mechanism in the protective box, so that the overlapping area of ​​the adjustment through hole (18) and the air hole (5) changes, and the air outlet area is dynamically adjusted. S4. Maintenance and cleaning: Regularly check the integrity of the superhydrophobic and oleophobic nano-coating on the inner wall of the air hole (5). If the coating is found to be worn, surface repair is required. The wind turbine assembly can be disassembled and maintained by removing the clamp assembly. Clean the residual impurities inside the air hole (5) to ensure that the airflow channel is unobstructed. S5. Fault diagnosis and emergency handling: When the sensing component detects a continuous abnormal signal, the PLC controller (26) triggers the alarm mechanism and automatically shuts down the electric push rod (16) in the corresponding area to prevent equipment damage; maintenance personnel can quickly locate the faulty component through the RFID tag and carry out targeted repair or replacement.
