[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] Heating furnaces typically have furnace doors with a thickness of 250-300mm. When the furnace door is opened to discharge material, not only will high-temperature hot air flow out in the direction of material discharge from the furnace opening, but a large amount of hot air will also overflow from both sides of the furnace door. Since the lifting mechanism of multi-layer furnace doors can only be designed on both sides of the furnace door, the hot air generated on the sides has a significant impact on the lifespan of the lifting mechanism, which can easily cause deformation or even damage to the lifting mechanism, seriously affecting the lifespan of other parts, and also exacerbating the loss of heat from the furnace opening, which is not conducive to the energy saving of the furnace.

[0004] To overcome the above drawbacks, existing technologies consider setting up heat insulation strips on both sides of the furnace door. However, the heat insulation strips may wear down during the process of pulling the furnace door up and down, leading to heat insulation failure.

[0022] Please see Figure 1-4 This embodiment provides a heat insulation device for the side of a furnace door, used to insulate the furnace door 200. The furnace door 200 is placed on one side of the furnace body 100. The heat insulation device for the side of the furnace door 200 includes: Fixed base 1, the fixed base 1 is fixedly connected to the outer wall of the furnace body 100, and the fixed base 1 is disposed near the side wall of the furnace door 200; The clamping device 2 includes a first connecting plate 21, a connecting column 22, a pressure sleeve 23, a pressure plate 24, and an elastic mechanism 25. The first connecting plate 21 is connected to the fixed base 1 and includes a screw hole 211. The outer wall of the connecting column 22 has an external thread. The connecting column 22 passes through the screw hole 211 and is threadedly connected to the first connecting plate 21. The connecting column 22 has a first end and a second end that are arranged opposite to each other. The first end of the connecting column 22 is arranged towards the side wall of the furnace door 200. The pressure sleeve 23 is sleeved on the first end of the connecting column 22 and the first end of the pressure sleeve 23 is connected to the pressure plate 24. The elastic mechanism 25 is sleeved on the pressure sleeve 23. The first end of the elastic mechanism 25 abuts against the second end of the pressure sleeve 23 and the second end of the elastic mechanism 25 abuts against the first end of the first connecting plate 21. A heat insulation strip 3 is installed at the first end of the pressure plate 24, and the first end of the heat insulation strip 3 is used to abut against the side wall of the furnace door 200.

[0023] Based on the above structure, during use, the furnace door 200 is opened. The specific opening and lifting methods can be found in CN116536498A, etc. The furnace door 200 is placed on one side by the corresponding lifting mechanism. After sliding friction with the first end of the heat insulation strip 3, the side wall of the furnace door 200 is positioned, causing the furnace door 200 to press against the heat insulation strip 3, which in turn presses against the pressure plate 24. The pressure sleeve 23 connected to the pressure plate 24 presses against the elastic mechanism 25. The elastic mechanism 25 undergoes elastic deformation under the pressure of the pressure sleeve 23 and the first connecting plate 21. In other words, the side wall of the furnace door 200 always receives compressive force from the heat insulation strip 3.

[0024] Even after the heat insulation strip 3 is thinned by friction against the side wall of the furnace door 200, the aforementioned elastic compressive force still exists, ensuring that the heat insulation strip 3 can always provide a corresponding compressive force against the side wall of the furnace door 200.

[0025] During the above process, the operator can rotate the connecting column 22 to accommodate the heat insulation strips 3 of different thicknesses installed on one side of the first end of the pressure plate 24. The operator can also replace the elastic mechanism 25 with different elastic strengths to provide different levels of compressive force on the side wall of the furnace door 200.

[0026] In the above scheme, the heat insulation strip 3 can be elastically pressed against the furnace door 200 by the clamping device, so that the heat insulation strip 3 is always pressed against the side wall of the furnace door 200, which has a better heat insulation effect. Specifically, by rotating the connecting column 22, the elastic mechanism 25 can provide a certain support force to the pressure plate 24, and the pressure plate 24 can press the heat insulation strip 3 on the first end against the side wall of the furnace door 200. This ensures that even if the heat insulation strip 3 is worn during the frequent replacement or opening of the furnace door 200, the heat insulation strip 3 itself can still be stably close to the side wall of the furnace door 200, ensuring a stable heat insulation effect.

[0027] Based on the above scheme, an annular gap 231 is included between the pressure sleeve 23 and the outer wall of the connecting post 22. The second end of the pressure sleeve 23 includes an annular portion 232 that fits against the outer wall of the connecting post 22. The first end of the connecting post 22 includes a radially protruding limiting portion 221. Specifically, the elastic mechanism 25 has a first pressed state and a second relaxed state. In the first state, the first end of the limiting portion 221 is flush with the first end of the pressure plate 24. In the second state, the second end of the limiting portion 221 fits against the annular portion 232. That is to say, the limiting portion 221 can actually restrict the pressure sleeve 23, the pressure plate 24, and the elastic mechanism 25 from disengaging from the connecting post 22. Furthermore, the first end face of the pressure plate 24 can always provide a complete plane for abutting the heat insulation strip 3. In this scheme, the movement of the limiting portion 221 in the annular gap 231 can be determined by the left and right lengths of the annular gap 231.

[0028] In another embodiment, the clamping device 2 further includes a guide rod 26, and the first connecting plate 21 further includes a guide hole 27. The first end of the guide rod 26 is fixedly connected to the pressure plate 24, and the second end of the guide rod 26 passes through the guide hole 27. The guide rod 26 is arranged parallel to the connecting post 22. During the contact and movement of the pressure plate 24 against the heat insulation strip 3, the guide rod 26 also undergoes a misalignment movement relative to the first connecting plate 21. Therefore, the guide rod 26 can play a role in assisting positioning and guiding the movement of the pressure plate 24, making the contact of the pressure plate 24 more stable.

[0029] In this embodiment, the elastic mechanism 25 is set as a metal helical spring, which has a stable structure and is easy to manufacture.

[0030] In another embodiment, the heat insulation device on the side of the furnace door 200 further includes a second connecting plate 28 and an adjusting screw 29. The adjusting screw 29 is threadedly connected to the fixing seat 1 in a direction parallel to the side wall of the furnace door 200. The second connecting plate 28 is sleeved on the adjusting screw 29 and is fixedly connected to the first connecting plate 21. The operator can rotate the adjusting screw 29 to move the position of the second connecting plate 28 parallel to the direction of the heat insulation strip 3. That is, the position of the pressure plate 24 on one side of the first connecting plate 21 can be moved up and down to accommodate heat insulation strips 3 of different widths. Specifically, the furnace body 100 includes a groove 101, and the pressure plate 24 includes a clamping plate 241 disposed opposite to the groove 101. The heat insulation strip 3 is embedded between the groove 101 and the clamping plate 241. The heat insulation strip 3 is positioned between the groove 101 and the clamping plate 241. By adjusting the position of the pressure plate 24, the distance between the groove 101 and the clamping plate 241 can be changed to accommodate heat insulation strips 3 of various sizes.

[0031] The heat insulation strip 3 in this utility model includes a steel plate 31 and a fiber cloth 32. The fiber cloth 32 is wrapped around the steel plate 31. In actual use, the outer multi-layer fiber cloth 32 can be worn thinner. After being worn to a certain extent, the fiber cloth 32 can be replaced, while the steel plate 31 can be used multiple times.

[0032] In fact, it is obvious that the heat insulation device on the side of the furnace door in this application can be configured as a pair mirror-image arranged on both sides of the furnace door 200, or multiple pairs arranged at intervals.

Therefore, all equivalent technical changes made using the contents of the present utility model specification and drawings are included in the scope of the patent application of the present utility model.

[0035] Although this application has been described by way of examples, those skilled in the art will know that this application has many modifications and variations without departing from the spirit of this application, and it is intended that the appended embodiments include these modifications and variations without departing from this application.
