Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] As attached Figure 1-7 As shown, the heat-insulating graphitization furnace includes a furnace body 1, furnace legs 2 are fixedly provided at the bottom of the furnace body 1, and a heat-insulating component is provided in the inner cavity of the furnace body 1.

[0026] The insulation component includes a spiral cooling pipe 3 and a spiral heating pipe 4 welded to the furnace body 1. The spiral cooling pipe 3 is welded to the inner cavity of the furnace body 1, and the spiral heating pipe 4 is welded to the inner cavity of the furnace body 1. Both the spiral cooling pipe 3 and the spiral heating pipe 4 are made of high-temperature alloy material. The spiral cooling pipe 3 is located on one side of the spiral heating pipe 4. Multiple cooling columns 5 are fixedly provided on the inner side of the spiral cooling pipe 3, and multiple heat-conducting columns 7 are fixedly provided on the inner side of the spiral heating pipe 4. Multiple transmission shells 6 are fixedly provided on the outer side of the multiple cooling columns 5 and heat-conducting columns 7. The cross-sectional shape of the transmission shells 6 and 8 is funnel-shaped.

[0027] In some embodiments, according to Figure 1 As shown, a water pump 9 is provided at one end of both the spiral cooling tube 3 and the spiral heating tube 4. An output pipe 12 is provided on one side of the water pump 9. Water can only come out when the water pump 9 is connected to the output pipe 12, and the water flow is ensured to flow through the spiral cooling tube 3.

[0028] In some embodiments, according to Figure 1 As shown, both the spiral cooling tube 3 and the spiral heating tube 4 have an output pipe 22 at their other ends. The output pipe 22 is connected to the water tank 10. The water tank 10 has an external connecting pipe 21. The output pipe 22 is connected to the water tank 10 so that the water can flow out and ensure that the water flows through the spiral heating tube 4 and circulates out through the external connecting pipe 21.

[0029] In some embodiments, according to Figure 1 As shown, the furnace body 1 has a crucible 11 inside the cavity and a furnace door fixing 13 on one side of the furnace body 1. The furnace body 1 is fixedly connected to the furnace door fixing 13. The furnace door fixing 13 is used to fix the furnace body 1 to ensure that the furnace door 14 does not shake or fall off during the opening and closing process.

[0030] In some embodiments, according to Figure 1 As shown, the furnace door 14 is connected to the inner wall hinge of the furnace door fixing 13. The furnace door 14 is fixed with a door handle 15. When opening the furnace door 14, the door needs to be opened by holding the door handle 15.

[0031] In some embodiments, according to Figure 1 As shown, a central cylinder 16 is provided inside the furnace body 1, and a transmission rod 17 is sleeved inside the central cylinder 16. The transmission rod 17 is made of high-temperature alloy. The central cylinder 16 and the transmission rod 17 are movably connected. Both the central cylinder 16 and the transmission rod 17 have a funnel-shaped cross-section. The central cylinder 16 and the transmission rod 17 work together to deliver the heat converted from heat more quickly.

[0032] In some embodiments, according to Figure 1 As shown, a heat-conducting plate 18 is provided on one side of the transmission rod 17, and a spiral heat-conducting tube 19 is fixedly provided on the outside of the heat-conducting plate 18. A heat-conducting shell 20 is fixedly provided on one side of both the spiral heat-conducting tube 19 and the heat-conducting plate 18. Both the heat-conducting plate 18 and the spiral heat-conducting tube 19 can conduct heat to the heat-conducting shell 20.

[0033] The working principle of this utility model is as follows: the spiral cooling pipe 3 and the spiral heating pipe 4 inside the furnace body 1 are used to assist in cooling and heating inside the furnace body 1.

[0034] If the interior of the furnace body 1 needs to be cooled, the spiral cooling pipe 3 needs to be opened. The water tank 10 next to the spiral cooling pipe 3 contains hot water and coolant. Then the water pump 9 will draw the coolant from the water tank 10 to the output pipe 12 and then transport it to the spiral heating cooling pipe 3. The spiral cooling pipe 3 is spirally wrapped around the inner cavity of the furnace body 1. So once the coolant enters the spiral cooling pipe 3, the heat-conducting columns 5 on the surface of the spiral cooling pipe 3 will concentrate the heat converted here and then transport it to the inner wall of the furnace body 1 by the transmission shell 6. The multiple heat-conducting columns 5 on the surface of the spiral cooling pipe 3 and the transmission shell 6 will absorb heat and convert it at the same time. The heat of the inner wall of the furnace body 1 will cool the interior of the furnace body 1. During the operation of the structure, only one of the spiral cooling pipe 3 and the spiral heating pipe 4 can be opened and used. The used coolant will flow out through the external pipe 21. When used next time, the water pump 9 will continue to draw out coolant to replenish it.

[0035] If the structure requires heating and insulation of the furnace body 1 during use, simply turn on the spiral heating tube 4. The water pump 9 will draw hot water from the water tank 10 to the output pipe 22 and then transport it to the inside of the spiral heating tube 4. The heat-conducting columns 7 on the surface of the spiral heating tube 4 will concentrate the heat converted into heat here, and then diffuse it over a wide area through the transmission shell 2 8. The multiple heat-conducting columns 7 on the surface of the spiral heating tube 4 and the transmission shell 2 8 will transport heat simultaneously. In addition, the heat of the inner wall of the furnace body 1 can keep the inside of the furnace body 1 warm and heat up. The furnace body 1 has a heat-conducting shell 20 on the outside. If it is necessary to cool the inside of the furnace body 1, the heat-conducting plates 18 on the outside of the furnace body 1 will also play a role. The heat will be gathered through the concentrator 16, and then the heat from the concentrator 16 will be transferred to the transmission rod 17 and then to the heat-conducting shell 20. The inside and outside of the furnace body 1 will work together to cool down, which can greatly improve the cooling speed and avoid wasting too much time waiting for the inside of the furnace body 1 to cool down on its own.

[0036] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
