The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude other embodiments. Embodiment 1:

[0020] Please refer to Figure 1 As shown, the utility model provides a baking device for a blast furnace iron runner, which includes a baking support frame 1. An insulating baking frame 2 is arranged inside the baking support frame 1. Vertical plates 6 are arranged above both sides of the inner cavity of the baking support frame 1. A support shaft 7 is fixedly installed in the middle of the outer side of the vertical plate 6. The outer end of the support shaft 7 is rotatably installed on the inner wall of the baking support frame 1. A lower fixed seat 8 is fixedly installed inside the lower end of the vertical plate 6. An upper fixed seat 11 is correspondingly arranged above the lower fixed seat 8. A speed reduction motor 13 is fixedly installed at the top of the right side of the baking support frame 1. The output shaft of the speed reduction motor 13 is fixedly installed at the end of the support shaft 7 on the right side.

[0021] The application of the upper fixed seat 11, the lower fixed seat 8 and the speed reduction motor 13 in this technical solution can fix the iron runner to be baked by integrating the upper fixed seat 11 and the lower fixed seat 8, and can install three iron runners at the same time. Moreover, during baking, the iron runner can rotate stably, avoiding baking residues. At the same time, the speed reduction motor 13 can control and adjust the rotation speed of the iron runner, improving the overall baking uniformity. Embodiment 2:

[0022] On the basis of Embodiment 1, as shown in the utility model Figure 4 As shown, guide slide bars 3 are fixedly installed at the bottoms of both sides of the inner cavity of the baking support frame 1. The inner ends of the guide slide bars 3 are clamped inside the insulating baking frame 2 and are slidably connected. A locking knob 4 is arranged below the inner cavity of the insulating baking frame 2. The locking end of the locking knob 4 penetrates through the insulating baking frame 2 and is tightly connected to the inner wall of the baking support frame 1.

[0023] Adopting the technical solution as shown in Figure 1 As shown, the inner ends of the guide slide bars 3 are located inside the sliding grooves. While limiting both sides of the insulating baking frame 2, balance can be maintained during height adjustment, avoiding tilting of the insulating baking frame 2 after movement. Moreover, baking equipment can be placed below, and the height of the placement space can also be adjusted. The locking knob 4 can adjust the lower end of the insulating baking frame 2 and can also lock and fix it. The locking knob 4 is made of high-temperature resistant material.

[0024] Secondly, in the technical solution, an installation groove 9 is horizontally opened inside the lower fixed seat 8. Heat-insulating filler pads 10 are fixedly installed on both the front and rear sides of the inner cavity of the installation groove 9; on both sides of the bottom of the upper fixed seat 11, clamping sleeves 12 are fixedly installed. The lower ends of the clamping sleeves 12 are clamped outside the upper ends of the vertical plates 6 and are tightly connected.

[0025] It adopts the one as shown in Figure 1In the technical solution shown, the installation groove 9 can accommodate the lower end of the iron runner, and the internal heat insulation filling pad 10 is used for reinforcement. The heat insulation filling pad 10 can resist temperatures above two hundred degrees and will not be affected. The clamping groove at the bottom of the upper fixing seat 11 can accommodate and fix the upper end of the iron runner. After the upper fixing seat 11 is installed above the vertical plate 6, the bottom is fixed by the clamping sleeve 12. Embodiment 3:

[0026] As shown in the present utility model Figures 1-4 As shown, at the bottom of both ends of the baking support frame 1, a bottom plate 5 is fixedly installed, and positioning holes are formed in the top of the bottom plate 5; sliding grooves are formed on both sides of the heat insulation baking rack 2, and the inner end of the guiding slide rod 3 extends into the interior of the sliding groove; there is a gap between the bottom of the heat insulation baking rack 2 and the bottom of the baking support frame 1, and the heat insulation baking rack 2 is designed in a bent shape.

[0027] By adopting the above technical solution, the bottom plate 5 and the positioning holes on the surface can install and fix the lower end of the baking support frame 1 and ensure the firmness of the overall device.

[0028] The working principle of the present utility model is as follows: Align the lower end of the iron runner to be baked with the installation groove 9 and force it to be inserted. Then, insert the upper end into the clamping groove inside the upper fixing seat 11. Next, align the clamping sleeve 12 at the bottom of the upper fixing seat 11 with the vertical plate 6 and insert it to complete the installation of both ends of the upper fixing seat 11. During baking, the reduction motor 13 drives the support shaft 7, the vertical plate 6, the upper fixing seat 11, and the lower fixing seat 8 to rotate to bake the iron runner evenly. In addition, the height of the heat insulation baking rack 2 can be adjusted by the locking knob 4 to make timely adjustments according to the baking requirements.
