Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0022] Specific implementation examples are given below.
[0023] Please see Figures 1 to 5 As shown, a fire passage cover for a roasting furnace includes a fire passage cover body 1. A sealing block 2 is slidably connected to the inner side of the fire passage cover body 1. Connecting blocks 3 are fixedly connected to the outer sides of both the sealing block 2 and the fire passage cover body 1. A connecting rod 4 is slidably connected to the inner side of the connecting block 3. A lifting frame 5 is fixedly connected to the outer side of the sealing block 2. A first limiting rod 6 is slidably connected to the inner side of one side of the lifting frame 5, and a first screw 7 is threadedly connected to the inner side of the other side of the lifting frame 5. The first screw 7 is rotatably connected to the fire passage cover body 1. A second screw 8 is rotatably connected to the outer side of the fire passage cover body 1. Gears 9 are fixedly connected to the outer sides of both the first screw 7 and the second screw 8, and the gears 9 mesh with each other. High-temperature resistant glass 10 is threadedly connected to the outer side of the second screw 8. A second limiting rod 11 is slidably connected to the inner side of the high-temperature resistant glass 10, and the second limiting rod 11 is slidably connected to the fire passage cover body 1. By setting up a first screw 7, a second screw 8, and a high-temperature resistant glass 10, the fire channel cover body 1 and the sealing block 2 are first placed over the fire opening for heat preservation. When observing the production situation inside the roasting furnace, the connecting rod 4 is pulled to separate from the connecting block 3. The first screw 7 drives the gear 9 on its outer side to rotate. Through the meshing of the gears 9, the second screw 8 rotates in the opposite direction. The first screw 7 drives the sealing block 2 to rise until it no longer obstructs the fire channel cover body 1, so that the user can observe. The second screw 8 drives the high-temperature resistant glass 10 to move down. The high-temperature resistant glass 10 blocks the gap between the raised sealing block 2 and the fire channel cover body 1 to reduce heat loss during observation. After observation, the high-temperature resistant glass 10 is raised away from the fire channel cover body 1 so that it is not easily baked by high temperature. The sealing block 2 is moved down to its original position to continue sealing, which improves the practicality of the device.
[0024] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, slots 101 are provided on the surface of the connecting rod 4 and the inner side of the fire duct cover body 1. A plug rod 12 is slidably connected to the inner side of the slot 101. By setting the slots 101 and the plug rod 12, when the sealing block 2 and the fire duct cover body 1 need to be pulled up at the same time, the connecting rod 4 can be pulled to drive multiple connecting blocks 3 to rise. The multiple connecting blocks 3 can drive the fire duct cover body 1 and the sealing block 2 to rise synchronously. When the connecting rod 4 is inserted into the inner side of the multiple connecting blocks 3, the plug rod 12 can be inserted into the slots 101 on the surface of the connecting block 3 and the inner side of the fire duct cover body 1, thereby further restricting the position of the connecting rod 4, making it less likely for the connecting rod 4 to slip when pulled up, making its movement more stable, and improving the stability of the device.
[0025] Furthermore, such as Figure 1 As shown, a sealing frame 13 is fixedly connected to the outside of the high-temperature resistant glass 10. The sealing frame 13 and the sealing block 2 are used together. In this step, by setting the sealing frame 13, when the high-temperature resistant glass 10 moves down to block the space between the sealing block 2 and the fire channel cover body 1, the sealing frame 13 is close to the upper side of the sealing block 2, thereby further sealing the gap between the sealing block 2 and the high-temperature resistant glass 10, thereby further reducing heat loss and improving the stability of the device's heat preservation.
[0026] Furthermore, such as Figure 1 As shown, a magnetic plate 14 is fixedly connected to the outside of the sealing circular frame 13, and a metal sheet 15 is fixedly connected to the outside of the sealing block 2. By setting the magnetic plate 14 and the metal sheet 15, when the sealing circular frame 13 blocks and seals the sealing block 2, the magnetic plate 14 is attracted to the outside of the metal sheet 15, thereby making the connection between the sealing circular frame 13 and the sealing block 2 more stable, making its blocking more stable, and improving the stability of the device in use.
[0027] Furthermore, such as Figure 1 and Figure 3 As shown, one end of the second screw 8 and one end of the second limiting rod 11 are both fixedly connected to a limiting plate 16. This step, by setting the limiting plate 16, ensures that when the high-temperature resistant glass 10 moves to its highest position, it is aligned and blocked by the limiting plate 16, making it less likely to separate from the second screw 8, thus improving the stability of the device.
[0028] Furthermore, such as Figure 1 and Figure 3As shown, a limiting frame 17 is fixedly connected to the outer side of the fire channel cover body 1, and the gear 9 and the limiting frame 17 are used together. This step, by setting the limiting frame 17, allows the gear 9 to rotate, and the limiting frame 17 cooperates with the fire channel cover body 1 to be close to the planes on the upper and lower sides of the gear 9, thereby further restricting the rotation of the gear 9, making its meshing more stable, and improving the stability of the device.
[0029] The working principle is as follows: First, the fire channel cover body 1 and sealing block 2 are placed on the fire opening for heat preservation. When observing the production situation inside the roasting furnace, the connecting rod 4 is pulled to separate from the connecting block 3 of the sealing block 2. The first screw 7 is rotated, which drives the gear 9 on its outer side to rotate. Through the meshing of the gears 9, the second screw 8 rotates in the opposite direction. The first screw 7 drives the sealing block 2 to rise until it no longer obstructs the fire channel cover body 1, so that the user can observe. The second screw 8 drives the high-temperature resistant glass 10 to move down. The high-temperature resistant glass 10 blocks the gap between the raised sealing block 2 and the fire channel cover body 1 to reduce heat loss during observation. After observation, the high-temperature resistant glass 10 is raised away from the fire channel cover body 1 so that it is not easily baked by high temperature. At the same time, the sealing block 2 is moved down to its original position to continue sealing.
