Description

Technical Field

[0001] This application relates to preheating collection and utilization technology for graphitization furnaces, and more particularly to a thermal energy utilization device for an Atchison graphitization furnace. Background Technology

[0002] The Atchison graphitization furnace is a key piece of equipment used in the production of graphite products. It converts electric current into heat energy to heat carbon calcined products to a high temperature of 2200℃-3000℃ to complete the graphitization process.

[0003] In existing graphitization furnaces, carbon calcined materials are placed in graphite crucibles and heated inside the furnace. After graphitization is completed, the graphite crucibles containing the materials are lifted out of the furnace by an overhead crane to cool naturally. After cooling, the materials are then transferred out.

[0004] In existing graphitization furnaces, the graphite crucible cools down slowly due to natural cooling, which affects the output efficiency. At the same time, the residual heat energy after graphitization cannot be recovered and utilized, which also results in the waste of heat energy. Utility Model Content

[0005] This application provides a thermal energy utilization device for an Atchison graphitization furnace to solve the problem that the graphite crucible cools slowly after graphitization in existing graphitization furnaces, and the thermal energy cannot be recovered and utilized.

[0006] This application provides an Atchison graphitization furnace thermal energy utilization device, including a graphitization furnace. Each furnace chamber of the graphitization furnace has partition walls on both sides. A heat exchanger for placing a graphite crucible is provided between two adjacent partition walls. The heat exchanger has a chamber capable of accommodating the flow of heat exchange medium. The heat exchanger is located at both ends of the flow of heat exchange medium and is connected to an inlet pipe and an outlet pipe, respectively.

[0007] Optionally, there may be multiple heat exchangers that can move along the length of the partition wall.

[0008] Optionally, the inlet pipe and outlet pipe are laid and fixed along the length of the partition wall, and the two ends of the heat exchanger are slidably connected on the inlet pipe and outlet pipe, respectively. The inlet pipe and outlet pipe are connected to the two ends of each heat exchanger through flexible telescopic hoses.

[0009] Optionally, the top surface of the heat exchanger is formed with a plurality of downwardly recessed heat exchange cavities, and the graphite crucible is placed inside the heat exchange cavities.

[0011] Compared with the prior art, the beneficial effects of the Atchison graphitization furnace thermal energy utilization device provided in this application are:

[0012] The high-temperature graphite crucible, after being removed from the furnace, is placed on a heat exchanger for heat exchange. The heat exchange medium absorbs heat energy, which rapidly cools the graphite crucible, facilitating its transfer and discharge, and improving discharge efficiency. Simultaneously, the residual heat in the graphite crucible is extracted through the heat exchange medium in the heat exchanger, allowing for the recovery and reuse of this heat energy.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0022] like Figures 1-3As shown, one embodiment of this application provides an Atchison graphitization furnace thermal energy utilization device, including a graphitization furnace 1. Each furnace chamber of the graphitization furnace 1 has partition walls 2 on both sides. A heat exchanger 3 for placing a graphite crucible 8 is provided between two adjacent partition walls 2. The heat exchanger 3 has a chamber that can accommodate the flow of heat exchange medium. The heat exchanger 3 is located at both ends of the heat exchange medium flow and is connected to an inlet pipe 5 and an outlet pipe 6, respectively.

[0023] During graphitization, the material is placed in a graphite crucible 8 and then heated in the furnace of the graphitization furnace 1. After graphitization, the upper covering material needs to cool down. During discharge, water enters the heat exchanger 3 through the inlet pipe 5. The graphite crucible 8 is lifted from the furnace by an overhead crane and placed on top of the heat exchanger 3. The water entering the heat exchanger 3 exchanges heat with the graphite crucible 8 at the top, and then the hot water is discharged and stored through the outlet pipe 6. The graphite crucible 8 is placed into the heat exchanger 3 in batches for cooling and heat exchange, and then removed by an overhead crane after heat exchange.

[0024] In this embodiment, the high-temperature graphite crucible 8 exiting the furnace is placed on the heat exchanger 3 for heat exchange. The heat exchange medium absorbs heat energy to rapidly cool the graphite crucible 8, facilitating its transfer and discharge, and improving discharge efficiency. Simultaneously, the residual heat in the graphite crucible 8 is obtained through the heat exchange medium in the heat exchanger 3, allowing the heat energy to be transferred to the heat exchange medium for recovery and reuse.

[0025] In one possible implementation, the heat exchangers 3 are multiple and can move along the length of the partition wall 2.

[0026] The heat exchanger 3 facilitates continuous operation. The graphite crucible 8 is placed on each heat exchanger 3 in sequence. During the heat exchange process of the first heat exchanger 3, the remaining heat exchangers 3 can be operated, saving time and improving the furnace output efficiency.

[0027] The heat exchanger 3 can move along the length of the partition wall 2, making it easy to remove the heat exchanger 3 and place the graphite crucible 8 below it. The distance that each heat exchanger 3 can move is equal to its width.

[0028] In one possible implementation, the inlet pipe 5 and the outlet pipe 6 are laid and fixed along the length of the partition wall 2, and the two ends of the heat exchanger 3 are slidably connected on the inlet pipe 5 and the outlet pipe 6, respectively. The inlet pipe 5 and the outlet pipe 6 are connected to the two ends of each heat exchanger 3 through flexible telescopic hoses.

[0029] The inlet pipe 5 and outlet pipe 6 serve as both the water supply and drainage pipes for the heat exchanger 3 and the track for its movement. The inlet pipe 5 and outlet pipe 6 can be connected to the side of the heat exchanger 3 via flexible hoses without affecting the water supply, drainage, or movement of the heat exchanger 3.

[0030] like Figure 4 and Figure 5As shown, in one possible implementation, the top surface of the heat exchanger 3 has a plurality of downwardly recessed heat exchange cavities 4, and the graphite crucible 8 is placed inside the heat exchange cavities 4.

[0031] The graphite crucible 8 is placed in the downward-recessed heat exchange cavity 4, which increases the contact area between the heat exchanger 3 and the graphite crucible 8, further improving the heat conduction efficiency and effect. It also makes the graphite crucible 8 more stable and avoids falling and causing safety hazards.

[0032] like Figure 4 and Figure 5 As shown, in one possible implementation, the bottom surface of the heat exchanger 3 is fixed with a plurality of heat-conducting fins 7 integrally formed therewith.

[0033] During graphitization, after the upper covering material of the graphitization furnace is opened, the heat exchanger 3 absorbs high-temperature heat energy from the bottom of the furnace. The heat-conducting plate 7 can improve the efficiency of heat transfer, so that the heat energy during the furnace opening waiting process can also be recovered and utilized, thereby improving the waste heat utilization rate.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
