[0022] The present application provides a heating furnace structure, Figures 1 to 5 The present application provides a heating furnace structure.

[0023] As Figures 1 to 5 The present application provides a heating furnace structure 100, which comprises a heating furnace body 1, a furnace door 2, a driving mechanism 3 and a transmission mechanism 4. The heating furnace body 1 is provided with a furnace opening 11. The driving mechanism 3 is arranged on the heating furnace body 1. The driving mechanism 3 drives the furnace door 2 to move through the transmission mechanism 4. The moving path of the furnace door 2 comprises a vertical segment and a horizontal segment. The starting point of the vertical segment is higher than the highest point of the furnace opening 11, and the ending point of the vertical segment is lower than the lowest point of the furnace opening 11. The furnace opening 11 is located at the ending point of the horizontal segment, so that the furnace door 2 can tightly cover the furnace opening 11.

[0024] The utility model discloses a driving mechanism 3 drives the stove door 2 moves, in the stove door 2 closing process, the stove door 2 moves along the vertical section of mobile path, when stove door 2 moves to the path end point of vertical section, stove door 2 is directly opposite the furnace mouth 11 of heating furnace body 1, the driving mechanism 3 can drive stove door 2 along the horizontal section of mobile path through transmission mechanism 4, until moving to the furnace mouth 11 position, to compact cover the furnace mouth 11, the utility model discloses the way of driving stove door 2 lifting realizes the switch of stove door 2, compared with the swing arm structure drive stove door 2 swing realizes the switch mode, occupies the space of furnace front extremely little, and through the linkage of driving mechanism 3, transmission mechanism 4 and stove door 2 realizes the lifting and compacting of stove door 2, makes driving mechanism 3 simultaneously as the driving source of lifting and compacting, need not set up additional compacting driving part in furnace front, further reduces the space of furnace front occupancy.

[0025] Need to explain, the driving mechanism 3 is air cylinder. Air cylinder can directly realize vertical drive compared with motor, need not set transmission part of variable rotation for translation.

[0026] Because the heating furnace body 1 and stove door 2 are rigid material, even if through transmission mechanism 4 compacting cover stove door 2 the furnace mouth 11, stove door 2 and furnace mouth 11 still exist between the tiny gap, therefore, in some embodiments, as shown in Figure 2 The side of stove door 2 facing heating furnace body 1 is provided with flexible sealing part 9, so that flexible sealing part 9 blocks the gap between stove door 2 and furnace mouth 11. By setting flexible sealing part 9 to block the gap between stove door 2 and furnace mouth 11, the sealing performance of heating furnace structure 100 is improved, and the quality of metallurgical products is improved.

[0027] Specifically, the flexible sealing part 9 is a ceramic fiber blanket. The ceramic fiber blanket can withstand high temperatures above 1000 DEG C and can maintain structural stability in the high-temperature environment of the heating furnace structure 100 for a long time, avoiding the sealing failure problem of traditional rubber sealing elements caused by high-temperature aging.

[0028] To ensure that the stove door 2 moves to the path end point of the vertical section to directly face the furnace mouth 11 of the heating furnace body 1 and stop vertical movement, in some embodiments, as shown in Figure 1 , Figure 2 And Figure 4As shown, the heating furnace structure 100 also includes a limiting mechanism 5 disposed on the heating furnace body 1. The limiting mechanism 5 is located at the end of the vertical path and has a limiting surface that can abut against the furnace door 2 to restrict the furnace door 2 from continuing to descend. With this configuration, after the furnace door 2 moves to the end of the vertical path, it abuts against the limiting surface of the limiting mechanism 5, which restricts the furnace door 2 from continuing to descend. At this time, the driving mechanism 3 can drive the furnace door 2 to move along the horizontal section of the moving path through the transmission mechanism 4 until it moves to the position of the furnace opening 11 to press and cover the furnace opening 11.

[0029] The specific structure of the limiting mechanism 5 is not limited, as long as the limiting surface of the limiting mechanism 5 can limit the furnace door 2 from continuing to descend. For example, in some embodiments, such as... Figure 1 , Figure 2 and Figure 4 As shown, the limiting mechanism 5 includes a bracket 51 and a roller 52. The roller 52 is fixed to the heating furnace body 1 by the bracket 51 and is rotatably mounted on the bracket 51. The limiting surface is formed on the roller 52. With this configuration, since the furnace door 2 stops descending under the restriction of the limiting mechanism 5, the driving mechanism 3 can then drive the furnace door 2 to move along the horizontal section of the moving path to approach the furnace opening 11 via the transmission mechanism 4. During the process of the furnace door 2 approaching the furnace opening 11, the furnace door 2 moves horizontally relative to the roller 52. Since the rolling friction is much smaller than the translational friction, the limiting mechanism 5 can be avoided from being damaged due to excessive friction when the furnace door 2 moves relative to the roller 52.

[0030] To improve the stability of the furnace door 2 during vertical movement, in some embodiments, such as... Figure 1 As shown, the heating furnace structure 100 also includes a mounting bracket 6 and a guide structure 7. The drive mechanism 3 and the transmission mechanism 4 are connected via the mounting bracket 6. The guide structure 7 is disposed on the heating furnace body 1 and extends along the height direction of the heating furnace body 1. The mounting bracket 6 is driven by the drive mechanism 3 to move on the guide structure 7. With this configuration, the drive mechanism 3 drives the mounting bracket 6 to move on the guide structure 7, causing the transmission mechanism 4 to move accordingly, thereby moving the furnace door 2. The guide structure 7 can eliminate horizontal shaking when the mounting bracket 6 moves, making the movement of the mounting bracket 6 more stable, thereby improving the stability of the furnace door 2 when it moves.

[0031] Furthermore, such as Figure 1As shown, there are two guide structures 7, and the mounting bracket 6 is movably mounted on the two guide structures 7. This arrangement, by using two guide structures 7, further improves the stability of the mounting bracket 6 during movement, thereby enhancing the movement stability of the furnace door 2.

[0032] In some embodiments, such as Figure 1 and Figure 2 As shown, the drive mechanism 3 is connected to the center of the top surface of the mounting bracket 6. Multiple connecting parts 21 are evenly distributed on both sides of the furnace door 2, and multiple transmission mechanisms 4 are correspondingly provided. Each transmission mechanism 4 is connected to a corresponding connecting part 21 on the furnace door 2. This arrangement increases the connection stability between the mounting bracket 6 and the furnace door 2 by increasing the number of transmission mechanisms 4. Simultaneously, the even distribution of the multiple connecting parts 21 and the multiple transmission mechanisms 4 ensures that the furnace door 2 is subjected to uniform force, preventing deformation over prolonged use due to uneven force distribution and ensuring good sealing performance.

[0033] The specific structure of the transmission mechanism 4 is not limited, as long as it ensures that the drive mechanism 3 can drive the furnace door 2 to move along the horizontal segment of the moving path through the transmission mechanism 4. For example, in some embodiments, such as... Figures 1 to 3 As shown, the transmission mechanism 4 includes a connecting plate assembly 41. One end of the connecting plate assembly 41 is rotatably connected to the furnace door 2, and the other end is rotatably disposed relative to the mounting frame 6. During the descent of the furnace door 2, the connecting plate assembly 41 extends vertically. When the furnace door 2 descends to the furnace opening 11, it stops descending under the restriction of the limiting mechanism 5, while the driving mechanism 3 continues to drive the mounting frame 6 to descend, causing the connecting plate assembly 41 to rotate relative to the mounting frame 6. The connecting plate assembly 41 gradually changes from vertical extension to horizontal extension, resulting in a gradual increase in the distance between the furnace door 2 and the mounting frame 6. Since the mounting frame 6 is located on the guide structure 7, it does not move horizontally, allowing the furnace door 2 to move horizontally, gradually approaching the furnace opening 11, thereby realizing the horizontal movement of the furnace door 2 along the moving path. The connecting plate assembly 41, through rotatable connection, converts the downward pressure applied by the driving mechanism 3 into a horizontal clamping force, resulting in a simple structure that is less prone to failure.

[0034] Furthermore, in some embodiments, such as Figure 3 and Figure 5As shown, the heating furnace structure 100 also includes a clamping adjustment part 8, which is adjustablely mounted on the mounting frame 6 in the clamping direction of the furnace door 2. The end of the connecting plate assembly 41 away from the furnace door 2 is rotatably connected to the clamping adjustment part 8. With this configuration, the horizontal clamping force can be adjusted by adjusting the position of the clamping adjustment part 8 on the mounting frame 6.

[0035] The specific structure of the connecting plate assembly 41 is not limited, as long as both ends of the connecting plate assembly 41 are rotatably connected to the furnace door 2 and the pressing adjustment part 8, respectively. For example, in some embodiments, such as Figure 3 and Figure 5 As shown, the connecting plate assembly 41 includes a first connecting plate 411 and two second connecting plates 412. The two ends of the first connecting plate 411 are respectively connected to the middle portions of the two second connecting plates 412. The transmission mechanism 4 also includes a rotating assembly 42. Two rotating assemblies 42 are provided between the two second connecting plates 412, and are located on opposite sides of the first connecting plate 411. Each rotating assembly 42 includes a pin 421 and a bearing 422 sleeved on the pin 421. The connecting plate assembly 41 is fixedly connected to the inner rings of the two bearings 422 via the two pins 421. The outer ring of one bearing 422 is fixedly connected to the furnace door 2, and the outer ring of the other bearing 422 is fixedly connected to the pressure adjustment part 8. This configuration, with the first connecting plate 411 and the two second connecting plates 412 working together, makes the connecting plate assembly 41 H-shaped, improving the structural strength of the connecting plate assembly 41 and preventing deformation due to prolonged stress, which could affect the sealing performance.

[0036] Furthermore, in some embodiments, such as Figure 3 and Figure 5 As shown, the transmission mechanism 4 further includes a fixing plate 43, which is connected to the outer wall of one of the second connecting plates 412. Both pins 421 have locking grooves into which the fixing plate 43 extends and engages. By setting the fixing plate 43, the pins 421 are fixedly connected to the connecting plate assembly 41, restricting the axial movement of the pins 421 and thus improving the stability of the connecting plate assembly 41 during rotation.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
