[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation, connection, and linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0027] Reference Figure 1 and Figure 2 This application provides a tunnel furnace device, including: a tunnel furnace body 100, a support 110 at the feed end of the tunnel furnace body 100 for mounting sensors; an exhaust device including a first exhaust hood 210, which is disposed above the feed end of the tunnel furnace body 100 and fixedly connected to the side wall of the tunnel furnace body 100, and has a vent 220 at its top; and a baffle 300, which is disposed below the vent 220, with both ends of the baffle 300 being snapped and fixed to the tunnel furnace body 100 and the support 110, respectively.

[0028] By setting a first exhaust hood 210 at the feeding end of the tunnel furnace body 100, not only can the hot air overflowing from the tunnel furnace body 100 be absorbed away, preventing the hot air from contacting the outer wall of the tunnel furnace body 100 and forming water droplets, thus ensuring the quality of subsequent sintering, but it can also absorb impurities at the feeding end, improving product quality. By setting the baffle 300 below the vent 220, it can block the dripping water droplets and also prevent foreign objects from falling and damaging the sensors on the support 110, ensuring the stability and safety of operation and improving product quality.

[0029] Reference Figures 1 to 3Specifically, the baffle 300 is provided with a first locking block 310, and the first locking block 310 is provided with a first locking groove 320 with its opening facing downwards. The tunnel furnace body 100 is provided with a first locking plate, which is embedded in the first locking groove 320. During installation, one end of the baffle 300 is placed on the locking plate and the locking plate is embedded in the first locking groove 320, thereby achieving the connection between the baffle 300 and the tunnel furnace body 100 and preventing the baffle 300 from detaching from the tunnel furnace body 100, which would affect the stability and safety of operation. Furthermore, the other end of the baffle 300 away from the tunnel furnace body 100 is provided with a second locking block 330, and the second locking block 330 is provided with a second locking groove 340. The bracket 110 is provided with a second locking plate, which is embedded in the second locking groove 340. The baffle 300 is attached to the bracket 110 and the bracket 110 is embedded in the second locking groove 340, thereby achieving the connection between the baffle 300 and the bracket 110 and improving the stability of the baffle 300. The baffle 300 has upward-curving bends around its perimeter, giving it a disc-shaped structure. This prevents water droplets or foreign objects from falling from the edges of the baffle 300, further enhancing its protective effect.

[0030] In this embodiment, extension plates are provided on both sides of the first exhaust hood 210, and the extension plates are fixedly connected to the tunnel furnace body 100. By fixing the first exhaust hood 210 to the tunnel furnace body 100 through the extension plates, the first exhaust hood 210 and the tunnel furnace body 100 are tightly fitted together, thereby improving heat absorption efficiency and ensuring product quality.

[0031] Reference Figure 1 and Figure 2 In some embodiments, the exhaust device further includes a second exhaust hood 230. An exhaust port 240 is provided on the top of the tunnel furnace body 100, and the second exhaust hood 230 is positioned above the exhaust port 240. By positioning the second exhaust hood 230 at the exhaust port 240, the gas discharged from the exhaust port 240 can be drawn away, ensuring a hygienic working environment. The exhaust port 240 is provided with an exhaust pipe 250, and the second exhaust hood 230 covers the exhaust pipe 250. By adopting the above structure, the top of the exhaust pipe 250 completely extends into the second exhaust hood 230, improving exhaust efficiency.

[0032] As can be conceived, the exhaust device also includes a connecting pipe 260 and an exhaust fan 270. One end of the connecting pipe 260 is connected to the vent 220 and the exhaust pipe 250, respectively, and the other end is connected to the exhaust fan 270. When the exhaust fan 270 operates, it creates a negative pressure inside the connecting pipe 260, thereby allowing the first exhaust hood 210 and the second exhaust hood 230 to draw in the gas. The structure is simple and the operation is convenient. The connecting pipe 260 is located above the tunnel furnace body 100 and is equipped with a support column 280. The bottom of the support column 280 is fixedly connected to the tunnel furnace body 100. The support column 280 supports the connecting pipe 260, improving the stability and reliability of the structure. It is easy to understand that the connecting pipe 260 is equipped with a filter 290, which is used to filter the gas inside the connecting pipe 260. By setting up the filter 290, the gas can be filtered to ensure that the final discharged gas meets environmental protection requirements.
