[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1 and Figure 4The utility model provides an embodiment of a high-temperature heat treatment furnace with an internal insulation structure, comprising a furnace body 1, the bottom of the left and right inner walls of the furnace body 1 are fixedly connected to supporting rods 3, the middle part of the outer wall of the supporting rod 3 is threadedly connected to a knob 4, grooves 5 are provided on the upper and middle parts of the left and right inner walls of the furnace body 1, a rack 6 is slidably connected inside the groove 5, a clamping plate 7 is fixedly connected to the top of the rack 6, a turning handle 8 is rotatably connected to the front side of the outer groove 5, and the other end of the turning handle 8 is fixedly connected to a gear 9, the gear 9 and the rack 6 are meshed and connected, and insulation layers 10 are installed on the left and right sides of the inner wall of the furnace body 1, and a heat insulation layer 11 is installed on the far side of the two insulation layers 10, and a sealing mechanism 2 is installed on the front side of the outer wall of the furnace body 1, and the sealing mechanism 2 is used to seal the furnace body 1; anti-collision shells 12 are installed at the four corners of the rear side of the outer wall of the furnace body 1, and the four anti-collision shells 12 are equidistantly distributed;

[0033] Specifically, during the operation of the heat treatment furnace, it is first necessary to open the furnace door panel 203, and then turn the handle 8. Driven by the handle 8, the gear 9 starts to rotate, and the gear 9 is engaged with the rack 6, so that the rack 6 can move up and down. As the rack 6 moves up and down, the clamping plate 7 also starts to move up and down accordingly. The function of the clamping plate 7 is to clamp the insulation structure to ensure its stability. The insulation structure is placed at the top position of the supporting rod 3, and the knob 4 needs to be turned to fix it, which realizes the convenient replacement of the insulation structure and greatly improves work efficiency and safety. The anti-collision shell 12 effectively reduces the damage caused to the operator by collision with the furnace body 1.

[0034] Reference Figure 2 and Figure 5 The sealing mechanism 2 includes a slide groove 201, which is provided at the upper and lower ends of the front side of the outer wall of the furnace body 1. A slide rail 202 is fixedly connected to the inside of the slide groove 201, and a door panel 203 is slidably connected to the other side of the slide rail 202. A handle 204 is fixedly connected to the middle part of the front side of the outer wall of the door panel 203. A threaded hole 205 is provided at the left end of the front side of the outer wall of the door panel 203. A fixing bolt 206 is threadedly connected to the middle part of the left end of the outer wall of the furnace body 1. A square groove 207 is provided at the front end of the left side of the inner wall of the furnace body 1. A magnet 208 is fixedly connected to the inside of the square groove 207. Support columns 13 are fixedly connected to the four corners of the bottom of the furnace body 1, and an anti-slip pad 14 is installed at the bottom of the support column 13.

[0035] Specifically, during the heat treatment process, the material to be heated is placed in a high-temperature heat treatment furnace. Through the coordinated action of the slide groove 201 and the slide rail 202, the handle 204 is pulled to move the door panel 203 along the direction of the slide groove 201 and the slide rail 202. The magnet 208 is designed to adsorb the door panel 203 so that it fits the furnace body 1 more closely, thereby avoiding heat leakage. The fixing bolt 206 is rotated to fix the door panel 203 through the threaded hole 205 to ensure that the door panel 203 will not be displaced in a high temperature environment, thereby maintaining its sealing. Compared with the traditional opening and closing door panel 203, this solution has significantly improved the sealing performance through these design improvements, has a more outstanding sealing effect, and ensures the efficiency and safety of the heat treatment process. The support column 13 supports the entire heat treatment furnace, and the anti-slip pad 14 can prevent the support column 13 from sliding.

[0036] Reference Figure 1 and Figure 3 A control panel 15 is installed in the middle of the top wall of the furnace body 1, and the control panel 15 is electrically connected to the furnace body 1; a hook 18 is fixedly connected to the upper middle part of the rear side of the outer wall of the furnace body 1, and a silicone glove 19 is installed at the bottom of the hook 18;

[0037] Specifically, the temperature in the furnace is controlled by the control panel 15 , and the silicone gloves 19 hung on the hooks 18 can reduce the risk of burns to operators when taking out heat-treated objects.

[0038] Reference Figure 2 and Figure 3 , the left and right sides of the outer wall of the furnace body 1 are threadedly connected with anti-scalding cotton 16, and the four corners of the outer wall of the anti-scalding cotton 16 are threadedly connected with bolts 17; the bottom of the furnace body 1 is fixedly connected to a tool box 20, and the front side of the outer wall of the tool box 20 is installed with a cabinet door 21;

[0039] Specifically, the anti-scalding cotton 16 effectively prevents burns to the operator and the high-temperature heat treatment furnace. The anti-scalding cotton 16 is fixed by bolts 17. The tool box 20 can store tools needed for the heat treatment furnace, and the cabinet door 21 ensures the integrity of the tool box 20.

[0040] Working principle: When the heat treatment furnace is working, open the door panel 203 and turn the handle 8. Under the action of the handle 8, the gear 9 starts to rotate, and the meshing rack 6 starts to move up and down, and the clamping plate 7 starts to move up and down to clamp the insulation structure. The insulation structure is placed on the top of the supporting rod 3, and the knob 4 is turned to fix the insulation structure, which realizes the convenient replacement of the insulation structure. The insulation layer 10 is made of insulation materials of different materials stacked alternately, which can include ceramic fiber and rock wool to effectively improve the insulation performance. The heat insulation layer 11 can reflect the heat in the furnace and is made of metal materials with high reflectivity to reduce heat loss. In actual application, a staggered composite insulation layer 10 is laid. Through this structural design, the insulation effect in the furnace can be significantly improved, energy consumption can be reduced, and the heat treatment quality of high-temperature carbon materials can be guaranteed at the same time.

[0041] After the material that needs to be heat treated is placed in the high-temperature heat treatment furnace, the handle 204 is pulled to move the door panel 203 through the action of the slide groove 201 and the slide rail 202, thereby realizing the sealing effect of the door panel 203 on the furnace body 1. The magnet 208 adsorbs the door panel 203 to further enhance the sealing effect, and the fixing bolt 206 is rotated so that the fixing bolt 206 fixes the door panel 203 through the threaded hole 205. Compared with the traditional opening and closing door panel 203, the sealing of this solution is stronger and has a better sealing effect.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
