Description

Technical Field

[0001] This application relates to the technical field of hot-dip galvanizing production equipment, and in particular to a furnace nose device that facilitates the removal of zinc ash. Background Technology

[0002] The furnace nose is a key component of a continuous hot-dip galvanizing production line. As a transitional channel connecting the annealing furnace and the zinc pot, its main function is to seal the process of the strip steel entering the zinc pot, maintain a reducing atmosphere to prevent oxidation, and thus isolate the air to ensure the coating quality.

[0003] In continuous hot-dip galvanizing production lines, zinc ash easily adheres to the inner wall of the furnace nose. These impurities can cause zinc ash defects on the surface of the strip steel. Therefore, manual cleaning is required by manually scraping or blowing with a hose through the small holes reserved at the top of the furnace nose. However, due to the limitation of the pipe diameter, this method is difficult to cover all cleaning areas and requires a lot of time and effort from workers. At the same time, there is a risk that the metal ash will be blown into the heating furnace. Utility Model Content

[0004] To improve the cleaning effect and operating efficiency of the furnace nose, this application provides a furnace nose device that facilitates the removal of zinc ash.

[0005] This application provides a furnace nose device for easy removal of zinc ash, which adopts the following technical solution: A furnace nose device for easy removal of zinc ash includes a furnace nose body with a cavity. The furnace nose body is provided with a vibration assembly, which includes a pneumatic vibrator and a gas pipe. The gas pipe is disposed on the pneumatic vibrator and is provided with a drive source for supplying gas. There are two pneumatic vibrators, which are respectively located on opposite sides of the furnace nose body.

[0006] By adopting the above technical solution, two pneumatic vibrators are located on opposite sides of the furnace nose body. The two pneumatic vibrators can stably output vibration to the inner wall of the furnace nose body. The high-frequency vibration force generated by the pneumatic vibrators causes the adhering zinc ash to detach from the inner wall under the vibration action, avoiding the limitations of relying solely on airflow. Workers do not need to manually clean the ash, reducing their workload and avoiding the risk of metal ash being blown into the heating furnace. This further ensures the surface quality of the coated products, reduces product downgrading caused by impurities and defects, maintains production continuity, and improves the overall operating efficiency and stability of the continuous hot-dip galvanizing production line.

[0007] Optionally, the gas pipeline is equipped with a control component for precisely regulating the flow rate within the gas pipeline.

[0008] By adopting the above technical solution, a control component is installed on the gas pipeline, which can precisely adjust the flow rate in the gas pipeline to meet the gas pressure control requirements. The operator can adjust the gas pressure in the gas pipeline to a certain value by adjusting the control component, so that the gas can be stably input into the pneumatic vibrator, thereby achieving stable high-frequency vibration of the pneumatic vibrator and better peeling off stubborn adhering impurities.

[0009] Optionally, the gas pipeline includes a first pipeline and a second pipeline, wherein the first pipeline and the second pipeline are threadedly connected and welded to both ends of the control component.

[0010] By adopting the above technical solution, the first and second pipes are threadedly connected and welded to both ends of the control component, so that the control component can be sealed and connected inside the gas pipe. The airtightness of the gas pipe is enhanced, reducing the possibility of gas escaping from the connection of the control component. At the same time, it can be adapted to high-temperature and corrosive working conditions, reducing the possibility of conventional pipe failure, thereby improving the stability of the furnace nose ash removal device. The staff can manually disassemble and install the control component, providing greater convenience for the staff.

[0011] Optionally, the control element includes a threaded ball valve.

[0012] By adopting the above technical solution, and through the control components including threaded ball valves, operators can manually control the gas pressure in the gas pipeline, reducing the possibility of excess airflow carrying impurities to diffuse, so that the gas pressure in the gas pipeline can be adapted to impurities of different thicknesses, thereby enhancing the applicability of the furnace nose cleaning device.

[0013] Optionally, the control element includes a solenoid valve.

[0014] By adopting the above technical solution, and through control components including solenoid valves, it is possible to remotely adjust the gas flow and pressure through the central control system. Operators do not need to approach the high-temperature furnace nose area to operate, avoiding the safety hazards of high-temperature environment to operators. At the same time, it can realize the synchronous control of multiple furnace nose ash cleaning devices, reduce manual inspection and operation costs, thereby improving the overall automation management level of the production line.

[0015] Optionally, the gas pipeline is equipped with a pressure gauge for monitoring the working gas pressure inside the gas pipeline.

[0016] By adopting the above technical solution, a pressure gauge is installed on the gas pipeline to detect the working gas pressure inside the gas pipeline. The pressure gauge can display the current gas pressure inside the gas pipeline in real time, so that the staff can monitor the gas pressure inside the gas pipeline and thus ensure that the vibration frequency of the pneumatic vibrator is stable within the optimal range.

[0017] Optionally, the gas pipeline is equipped with a T-junction, the two ends of which are respectively connected to the gas pipelines on both sides. The T-junction is used to balance the gas pressure of the two gas pipelines.

[0018] By adopting the above technical solution, the two ends of the three-way pipe are connected to the two pipes respectively, so that the three-way pipe can balance the air pressure of the two air paths. The staff can simultaneously adjust the air pressure of the two air paths, so as to balance the air pressure in the gas pipeline and thus enhance the overall stability of the device.

[0019] Optionally, the pneumatic vibrator is provided with fasteners, the pneumatic vibrator is provided with a mounting plate, the mounting plate is provided with mounting holes for fasteners to be inserted, and the furnace nose body is provided with a fixing plate, the fixing plate is provided with fixing holes for fasteners to be inserted.

[0020] By adopting the above technical solution, the mounting plate has mounting holes for fasteners to be inserted, and the fixing plate has fixing holes for fasteners to be inserted. By inserting the fasteners through the mounting holes into the fixing holes, the operator can fix the pneumatic vibrator to the furnace nose body, reducing the possibility of the vibrator falling off the furnace nose body when it is started, thereby enhancing the overall stability of the equipment and enabling the pneumatic vibrator to continuously vibrate the furnace nose body.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. Two pneumatic vibrators are located on opposite sides of the furnace nose body. These two pneumatic vibrators can stably output vibration to the inner wall of the furnace nose body. The high-frequency vibration force generated by the pneumatic vibrators causes the adhering zinc ash to detach from the inner wall under the vibration, avoiding the limitations of relying solely on airflow. Workers do not need to manually clean the ash, reducing their workload and avoiding the risk of metal ash being blown into the heating furnace. This further ensures the surface quality of coated products, reduces product downgrading caused by impurities and defects, maintains production continuity, and improves the overall operating efficiency and stability of the continuous hot-dip galvanizing production line.

[0022] 2. The gas pipeline is equipped with a control device that can precisely adjust the flow rate within the gas pipeline to meet the gas pressure control requirements. By adjusting the control device, the operator can control the gas pressure within the gas pipeline to a certain value, allowing the gas to be stably input into the pneumatic vibrator. This enables the pneumatic vibrator to achieve stable high-frequency vibration, thus better removing stubborn adhering impurities. Attached Figure Description

The gas pipe 22 is fixedly connected to the pneumatic vibrator 21, which is fixedly connected to the outer surface of the furnace nose body 1. Two pneumatic vibrators 21 are provided, located on opposite sides of the furnace nose body 1. The high-frequency vibration force generated by the pneumatic vibrators 21 allows the adhered zinc ash to detach from the inner wall under the vibration.

[0027] Reference Figure 2 A control component 3 is fixedly connected to the gas pipeline 22. The control component 3 includes a threaded ball valve and is used to precisely regulate the flow rate within the gas pipeline 22. There are two control components 3, located on either side of the two pneumatic vibrators 21.

[0028] Reference Figure 2 The gas pipeline 22 includes a first pipeline 221 and a second pipeline 222, which are threaded to opposite end faces of the control component 3. The first pipeline 221 is a rigid pipe, and the second pipeline 222 is a flexible pipe. The flexibility of the flexible pipe allows operators to adjust its bending direction. The controller also includes a solenoid valve, allowing operators to switch between manual and remote automated control without modifying the gas pipeline 22. The solenoid valve can remotely adjust the gas flow and pressure through the production line's central control system to achieve synchronous control of multiple furnace nose cleaning devices.

[0029] Reference Figure 2 A pressure gauge 4 is fixedly connected to the gas pipeline 22. The pressure gauge 4 is used to detect the working gas pressure in the gas pipeline 22. The pressure gauge 4 can display the current gas pressure in the gas pipeline 22 in real time, which is convenient for staff to monitor.

[0030] Reference Figure 2 A three-way pipe 223 is fixedly connected between the two second pipes 222. The two ends of the three-way pipe 223 are respectively connected to two gas paths. The pressure gauge 4 is fixedly connected to the three-way pipe 223. The three-way pipe 223 is used to balance the gas pressure of the two gas paths, so that the gas path is divided into two paths, which are controlled by different control components 3 respectively.

A mounting plate 211 is integrally formed on the surface of the pneumatic vibrator 21 near the furnace nose body 1. The mounting plate 211 has mounting holes 212 for the fasteners 12 to be inserted.

[0032] Reference Figure 1 , Figure 2 and Figure 3 A fixing plate 11 is integrally formed on the outer surface of the gas furnace nose body 1. The fixing plate 11, which abuts against the pneumatic vibrator 21, has fixing holes 111 for fasteners 12 to be inserted. The pneumatic vibrator 21 is installed on the furnace nose body 1 by inserting the fasteners 12 through the mounting holes 212 into the fixing holes 111.

[0033] The implementation principle of the furnace nose device for easy removal of zinc ash in this application embodiment is as follows: gas enters the device from the inlet end of the three-way pipe 223. The pressure gauge 4 displays the current gas pressure in the gas pipeline 22 in real time for the staff to monitor. The gas entering the three-way pipe 223 is divided into two paths, which pass through the corresponding control components 3 respectively. The staff controls the flow rate by adjusting the opening and closing degree of the control components 3, so as to stabilize the gas pressure in the gas pipeline 22 at a certain value, so that the zinc ash on the inner wall of the furnace nose body 1 can be removed under the high-frequency vibration force of the pneumatic vibrator 21.
