The accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this application. Furthermore, the same reference numerals denote the same parts throughout the drawings. In the drawings:

[0030] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings.

[0031] The accompanying drawings illustrate various structural schematics according to embodiments of this application. These drawings are not to scale, and some details have been enlarged for clarity, and some details may have been omitted. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art can design regions / layers with different shapes, sizes, and relative positions as needed.

[0032] To better understand the above technical solutions, the following will describe the above technical solutions in detail with reference to specific implementation methods. It should be understood that the embodiments of this disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0033] The furnace nose is the connection point between the heating furnace and the zinc pot. Products output from the heating furnace, such as zinc-aluminum-magnesium alloys and high-strength hot-dip galvanized steel strips, are fed into the zinc pot through the furnace nose for galvanizing.

[0034] Cameras are typically installed inside the furnace nose to observe the overflow status and cleanliness. Taking cold-rolled high-end automotive outer panels as an example, during the production process, the zinc ash inside the furnace nose can cause the camera to adhere to the zinc ash, making it impossible to see the overflow status and cleanliness inside the furnace nose, thus preventing the outer panels from being produced normally.

[0035] In view of this, this application provides a purging device 100, please refer to...Figure 1 , Figure 1 This is a wireframe diagram of the purging device 100 in this embodiment. The purging device 100 is applied to a furnace nose 108, which is located between the heating furnace and the zinc pot. A camera mechanism 109 is installed inside the furnace nose 108. The purging device 100 includes: a gas source 101 storing purging gas; a purging mechanism 102 connected to the purging interface of the camera mechanism 109; a first gas supply branch 103 with its inlet connected to the gas source 101 and its outlet connected to the purging mechanism 102; a first valve 104 located in the first gas supply branch 103, the opening of which is adjustable; a second gas supply branch 105 with its inlet connected to the gas source 101 and its outlet connected to the purging mechanism 102; a second valve 106 located in the second gas supply branch 105; and a controller 107 electrically connected to the second valve 106 for controlling the opening or closing of the second valve 106.

[0036] The purging device 100 provided in this embodiment controls the opening of the first valve 104 to deliver a continuous micro-airflow to the camera via the first air supply pipe for stable purging, ensuring a stable purging flow for the camera during normal production. During production, the second valve 106 is opened as needed to deliver a strong airflow to the camera via the second air supply pipe, efficiently cleaning the camera and preventing excessive zinc ash from falling into the camera area, which could cause problems with the steel strip output. Simultaneously, the camera's clarity is consistently maintained, providing conditions for stable production of high-end automotive outer panels. Furthermore, the two branches complement each other; if one branch fails, the other continues to operate, further ensuring production efficiency.

[0037] Understandable Figure 1 The arrow pointing from the first valve 104 to the first gas supply branch 103 indicates that the first valve 104 can control the gas flow rate of the first gas supply branch 103 by adjusting its opening degree. The arrow pointing from the second valve 106 to the second gas supply branch 105 indicates that the second valve 106 can control the on / off state of the second gas supply branch 105.

[0038] In some alternative implementations, the first valve 104 is a manual valve and the second valve 106 is a solenoid valve.

[0039] The manual valve is low-cost, and its opening is manually adjusted to a set value. This manual valve maintains a consistent flow rate for purging the camera mechanism 109, ensuring its clarity throughout the production process. To more fully and effectively purge the camera mechanism 109, the second valve 106 uses a solenoid valve, enabling remote control and providing high-flow purging capabilities, thus significantly improving the cleaning capacity and efficiency of the camera mechanism 109. For example, during adjustments to the outer panel's production status, the second air supply branch 105 can be repeatedly opened and closed by starting and stopping the solenoid valve to achieve high-flow repeated purging, further ensuring the clarity of the camera mechanism 109.

[0040] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be implemented independently or in combination with each other. The same or similar concepts or processes may not be described again in some embodiments.

[0041] Below, in conjunction with Figure 2 The purging device 100 provided in the embodiments of this application will be described in detail. This example does not constitute a limitation on the embodiments of this application. The following embodiments can be combined with each other, and the same or similar concepts or processes will not be described again.

[0042] like Figure 2 As shown, the camera mechanism 109 includes a first camera 201, and the purging mechanism 102 includes a first purging branch 1021, the outlet of which is connected to the first purging interface of the first camera 201; the purging mechanism 102 also includes a main pipe 1022, the inlet of which is connected to the outlet of the first air supply branch 103 and the second air supply branch 105 respectively, and the outlet is connected to the inlet of the first purging branch 1021.

[0043] Still Figure 2 As shown, the camera mechanism 109 also includes a second camera 202, and the purging mechanism 102 includes a second purging branch 1023. The outlet of the second purging branch 1023 is connected to the second purging interface of the second camera 202; the outlet of the main pipe 1022 is connected to the outlet of the second purging branch 1023.

[0044] It is understood that the first camera 201 and the second camera 202 are cameras with purge channels. For example, the exterior of the first camera 201 has a first transparent window for heat insulation. The first transparent window itself has a purge channel. The purge channel of the first camera 201 is connected to the purge channel of the first transparent window. The outlet of the first purge branch 1021 is connected to the first purge interface of the first purge channel of the first camera 201. The first purge branch 1021 sends the gas delivered through the main pipe 1022 into the first camera 201 through the first purge interface to purge the first transparent window.

[0045] The second camera 202 has a second transparent window for heat insulation on its exterior. The second transparent window itself has a purge channel. The purge channel of the second camera 202 is connected to the purge channel of the second transparent window. The outlet of the second purge branch 1023 is connected to the second purge interface of the second purge channel of the second camera 202. The second purge branch 1023 sends the gas delivered through the main pipe 1022 into the second camera 202 through the second purge interface to purge the second transparent window.

[0046] The first camera 201 and the second camera 202 of the camera mechanism 109 are respectively set on the transmission side and the working side of the strip 203 passing through the furnace nose 108, so as to facilitate observation of the strip 203 in two directions. The first purging branch 1021 and the second purging branch 1023 are connected to the first camera 201 and the second camera 202 respectively through the main pipe 1022, so that the first purging branch 1021 and the second purging branch 1023 can purge the first camera 201 at the same time, or purge the first purging branch 1021 and the second purging branch 1023 at the same time. The two cameras share the air source 101 and do not interfere with each other.

[0047] In some alternative implementations, it remains as follows Figure 2 As shown, the purging device 100 also includes a flow meter 204, which is disposed on the first gas supply branch 103 and located between the first valve 104 and the purging mechanism 102. The flow meter 204 monitors the gas flow rate in the first gas supply branch 103 in real time to adjust the opening of the first valve 104. The flow meter 204 can be an electronic flow meter, which will not be described in detail here.

[0048] In some alternative implementations, it remains as follows Figure 2 As shown, the purging device 100 also includes a one-way valve 205, which is disposed on the first gas supply branch 103. Specifically, the one-way valve 205 is located between the flow meter 204 and the main pipe 1022 of the purging mechanism 102. Since there is airflow in the furnace nose 108, the one-way valve 205 prevents the airflow in the furnace nose 108 from entering the first gas supply branch 103, thus preventing gas backflow.

[0049] In some alternative implementations, it remains as follows Figure 2 As shown, the purging device 100 also includes a ball valve 206, which is disposed on the second air supply branch 105 and is located between the air source 101 and the second valve 106.

[0050] During normal production, ball valve 206 is normally open. When the second valve 106 needs maintenance, ball valve 206 closes to cut off the second gas supply branch 105, preventing gas leakage and facilitating disassembly, inspection, and replacement of the second valve 106. Ball valve 206 can also be used to cut off the second gas supply branch 105 when the second valve 106 is damaged, preventing the second gas supply branch 105 from being normally open due to damage to the second valve 106. Ball valve 206 can be an electrically controlled ball valve, electrically connected to the controller 107 for control, or it can be a manually controlled ball valve.

[0051] Based on the same inventive concept, this application also provides a camera device applied to a furnace nose 108, which is disposed between the heating furnace and the zinc pot, such as... Figure 3 As shown, the camera device 300 includes: the camera mechanism 109 provided in the above embodiment and the purging device 100 provided in the above embodiment, with the camera mechanism 109 disposed inside the furnace nose 108.

[0052] In some alternative embodiments, the camera mechanism 109 includes a camera and a transparent window disposed outside the camera. The camera has a purge channel communicating with the transparent window, and the outlet of the purge mechanism 102 of the purge device 100 is connected to the purge interface of the purge channel on the camera.

[0053] Based on the same inventive concept, this application also provides a furnace nose, which is disposed between the heating furnace and the zinc pot, such as... Figure 4 As shown, the camera device 300 provided in the above embodiment is installed inside the furnace nose 400.
