[0002] An Acheson furnace is a heat treatment device for graphitizing carbonaceous materials. It makes carbide transform into graphite at high temperature through resistance heating. During the heating process of the Acheson furnace, the internal temperature can rise above 3000°C. And to ensure that carbon atoms can be fully rearranged to form high-quality graphite, it is necessary to keep the temperature for a period of time after heating. With the setting of the insulation layer, the temperature dissipation speed in the furnace is slow, and it takes several days to open the furnace under natural conditions, which leads to a reduction in the graphite production efficiency. Therefore, it is necessary to cool down the Acheson furnace after heating and insulation to improve the production efficiency.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0040] For the embodiments, please refer to Figures 1-12 As shown in the figure, an Acheson furnace layered cooling device includes a furnace body 11 arranged on a bottom plate 1; as Figure 1 shown in the figure, two layered cooling components 2 are symmetrically arranged in the upper opening of the furnace body 11, side cooling components 3 are arranged on both opposite side walls of the furnace body 11, a tin liquid cooling component 4 connected to the two layered cooling components 2 and a water cooling component 5 connected to the two side cooling components 3 are installed on the bottom plate 1. At high temperature, the tin liquid cooling component 4 is used to transport tin liquid into the two layered cooling components 2, and the tin liquid is used to take away the high temperature generated after the production of the furnace body 11 for preliminary cooling;

[0041] As Figure 2 and Figure 3 shown in the figure, a plurality of crucibles 12 are arranged in a rectangular array in the furnace body 11, and the cooling ends of the two layered cooling components 2 are inserted into the gaps between the plurality of crucibles 12. The tin liquid flows in the layered cooling components 2, thereby taking away the high temperature inside the furnace body 11;

[0042] As Figure 3 、 Figure 4 and Figure 5 shown in the figure, the layered cooling component 2 includes a heat preservation plate 21, a connecting channel 27 arranged in an S-shaped intermittent arrangement is opened in the heat preservation plate 21, a plurality of insertion plates 26 are fixedly connected to the bottom of the heat preservation plate 21 at the intermittent positions of the connecting channel 27, the insertion plates 26 are evenly inserted into the gaps between the plurality of crucibles 12, a U-shaped channel 28 is arranged in each insertion plate 26, and both ends of the U-shaped channel 28 are communicated with the connecting channel 27. The tin liquid circulates in the connecting channel 27 and the U-shaped channel 28 to take away the high temperature inside the furnace body 11 and between the plurality of crucibles 12, so that the temperature inside the furnace body 11 is initially reduced, and the materials in the plurality of crucibles 12 can be cooled rapidly. Moreover, using tin liquid for cooling can effectively avoid the formation of defective products due to too fast cooling speed of the materials;

[0043] As Figure 4 and Figure 5In the middle, a liquid inlet 24 and a liquid outlet 25 are fixedly connected to the head and tail openings of the connecting channel 27 respectively, and the liquid inlet 24 and the liquid outlet 25 form a loop by communicating with the tin liquid cooling assembly 4. Above the heat preservation plate 21, a first overhead plate 22 and a second overhead plate 23 are arranged in sequence. The heat preservation plate 21, the first overhead plate 22 and the second overhead plate 23 are used to keep the temperature required during raw material production. After production, the second overhead plate 23, the first overhead plate 22 and the heat preservation plate 21 are lifted out of the opening of the furnace body 11 layer by layer by a crane, which can achieve the effect of layered cooling and further accelerate the cooling speed.

[0044] Such as Figure 1 , Figure 2 And Figure 10 In the middle, the layered cooling assembly 2 further includes two positioning pipes 212 fixed by support rods 211. One-way sealing rings 213 are fixedly connected to the ports of the positioning pipes 212. Inner pipes 214 are slidably arranged in the one-way sealing rings 213. Second sealing rings 215 are fixedly connected to the ends of the inner pipes 214 located in the positioning pipes 212. The ends of the two inner pipes 214 can be respectively connected to the liquid inlet 24 and the liquid outlet 25. The ends of the two positioning pipes 212 are respectively communicated with the tin liquid cooling assembly 4 through pipelines. The inner pipes 214 slide and expand in the positioning pipes 212 to connect and disconnect with the liquid inlet 24 and the liquid outlet 25, playing a connecting role. When in use, it is convenient to lift the heat preservation plate 21 out of the opening of the furnace body 11 and take out the crucible 12 from the furnace body 11, and ensure the circulation of the tin liquid.

[0045] Such as Figure 2 And Figure 4 In the middle, brackets 29 are fixedly connected to the heat preservation plate 21, the first overhead plate 22 and the second overhead plate 23. Positioning ribs 210 that are fitted with the brackets 29 are fixedly connected to the bottoms of the first overhead plate 22 and the second overhead plate 23. The first overhead plate 22 and the second overhead plate 23 are supported and overhead arranged through the brackets 29 and the positioning ribs 210. Slag materials are laid on the heat preservation plate 21, the first overhead plate 22 and the second overhead plate 23. Four connecting grooves 13 are opened on the side wall of the furnace body 11. The liquid inlets 24 and the liquid outlets 25 in the two layered cooling assemblies 2 are respectively arranged in the four connecting grooves 13. Slag materials are laid between the heat preservation plate 21, the first overhead plate 22 and the second overhead plate 23 and above the second overhead plate 23 to ensure the heat preservation effect in the furnace body 11 and avoid too fast heat loss in the furnace body 11. And the crane is connected to the brackets 29 on the heat preservation plate 21, the first overhead plate 22 and the second overhead plate 23 to lift and carry them.

[0046] Such as Figure 2 , Figure 11 And Figure 12Among them, the side cooling assembly 3 includes an installation groove 31 formed on the outer wall of the furnace body 11. A fixed shell 32 is fitted in the installation groove 31. A plurality of heat dissipation fins 33 are fixedly connected horizontally in the fixed shell 32. A cooling pipe 34 is bent in an S shape in the fixed shell 32, and the cooling pipe 34 passes through and is fixed between the plurality of heat dissipation fins 33. The head and tail ends of the cooling pipe 34 respectively penetrate the fixed shell 32 and extend outside the furnace body 11 to be provided with a liquid inlet 35 and a liquid outlet 36. The liquid inlet 35 and the liquid outlet 36 are both communicated and arranged in the water cooling assembly 5. A heat preservation cover 37 is rotatably installed at the lower edge of the opening of the installation groove 31. Locking buckles 38 for locking are installed on both sides of the heat preservation cover 37, and the heat preservation cover 37 can be locked outside the installation groove 31 by using the locking buckles 38. After the temperature in the furnace body 11 is lower than the temperature of the tin liquid, the water cooling assembly 5 is used to convey the cooling liquid into the side cooling assemblies 3 on both sides. The cooling liquid circulates in the cooling pipe 34 and the water cooling assembly 5 to further reduce the temperature of the furnace body 11. And under the action of the heat dissipation fins 33, the heat dissipation area of the furnace body 11 can be increased, and the dissipation of the temperature can be accelerated. When processing, the heat preservation cover 37 is closed outside the installation groove 31, which can avoid the loss of heat in the furnace body 11 and play a role in heat preservation.

[0047] As Figure 1 and Figure 6 Among them, the tin liquid cooling assembly 4 includes a heat preservation tank 41 fixed on the bottom plate 1. A tin delivery pipe 42 is installed at the lower part of the heat preservation tank 41, and the end of the tin delivery pipe 42 is communicated with two of the positioning pipes 212 through a pipeline. A tin liquid pump 43 is installed on the tin delivery pipe 42. A tin return pipe 44 is installed on the heat preservation tank 41, and the end of the tin return pipe 44 is connected to the other two positioning pipes 212. A heating control module 45 is installed on the heat preservation tank 41. The acting end of the heating control module 45 penetrates and is installed with a heating rod 46 in the heat preservation tank 41. A first valve 47 is installed on the tin delivery pipe 42. The tin liquid pump 43 is used to convey the tin liquid in the heat preservation tank 41 into the two layered cooling assemblies 2. The circulating tin liquid flows back into the heat preservation tank 41 through the tin return pipe 44. The heating rod 46 is used to heat the tin liquid in the heat preservation tank 41 to prevent the tin liquid from solidifying due to the decrease of the tin liquid temperature during shutdown, as Figure 6 、 Figure 8 and Figure 9In it, a sunken groove portion 48 is recessed inward at the bottom of the heat preservation tank 41. A motor 49 is installed at the bottom of the heat preservation tank 41 through a fixing member. The output end of the motor 49 is fixedly connected to a rotating shaft 411. And the rotating shaft 411 is rotatably arranged below the heat preservation tank 41 through a shaft sleeve 410. The top end of the rotating shaft 411 extends into the sunken groove portion 48 and is fixedly connected to a magnet 412. A closed shell 413 is rotatably installed at the inner bottom of the heat preservation tank 41 outside the sunken groove portion 48. A magnetic ring 414 is fixedly connected to the inner wall of the closed shell 413. A plurality of stirring blades 415 are fixedly connected to the outer wall of the closed shell 413. By adsorbing and driving with the magnet 412 and the magnetic ring 414, the stirring blades 415 are driven to rotate in the heat preservation tank 41 to stir the tin liquid in the heat preservation tank 41, increase its fluidity, avoid uneven heating caused by the deposition of tin liquid, and through the non-contact drive of the magnet 412 and the magnetic ring 414, avoid the leakage of tin liquid in the heat preservation tank 41.

[0048] As Figure 1 and Figure 6 In it, the water cooling assembly 5 includes a liquid storage tank 51 fixed on the bottom plate 1 and a sleeve 52 fixed outside the tin return pipe 44. A water return pipe 58 is installed on the liquid storage tank 51. A first water outlet pipe 53 is installed at the side bottom of the liquid storage tank 51. A water pump 54 is installed on the first water outlet pipe 53. An inlet water pipe 55 is installed on the sleeve 52. A second valve 56 is installed on the inlet water pipe 55. And the end of the first water outlet pipe 53 is communicated with the inlet water pipe 55 and the liquid inlet 35 in two side cooling assemblies 3 through pipelines respectively. A second water outlet pipe 57 is installed on the sleeve 52. The end of the water return pipe 58 is communicated with the liquid discharge port 36 in two side cooling assemblies 3 and the second water outlet pipe 57 through pipelines respectively. Pressure relief assemblies 6 are installed on both the water return pipe 58 and the sleeve 52. The second water outlet pipe 57 is connected to the stage of the water return pipe 58 between the pressure relief assembly 6 and the liquid storage tank 51. The water pump 54 is used to transport the coolant in the liquid storage tank 51 to two side cooling assemblies 3 to cool the furnace body 11 for the second time and improve the cooling effect. And by transporting the coolant into the sleeve 52 through the inlet water pipe 55, the tin liquid flowing back in the tin return pipe 44 can be cooled, so that the temperature of the tin liquid circulating out of the furnace body 11 is reduced, to further improve the cooling effect of the tin liquid on the furnace body 11.

[0049] As Figure 1 、 Figure 6 and Figure 7Among them, the pressure relief component 6 includes a steam chamber 61. A pressure relief pipe 62 is fixedly connected to the lower part of the steam chamber 61. Supported by the pressure relief pipe 62, the steam chamber 61 is fixed on the water return pipe 58 and the casing 52. A nozzle 63 is fixedly connected to the end of the pressure relief pipe 62 located inside the steam chamber 61. A generator 64 is installed on the side wall of the steam chamber 61 through a fixing member. The rotating shaft of the generator 64 penetrates through the steam chamber 61 and is fixedly connected with a blade 65. The center line of the nozzle 63 is tangent to the rotation trajectory of the blade 65. An exhaust pipe 66 is installed on the steam chamber 61, and the end of the exhaust pipe 66 extends outdoors. When the coolant is transported to the side cooling component 3 and steam is generated inside the casing 52 due to high temperature, the high-pressure steam will move upward and enter the pressure relief pipe 62 through the water return pipe 58 and the casing 52, and is blown at high speed towards the blade 65 through the nozzle 63 to make it rotate. When the blade 65 rotates, it will drive the rotating shaft of the generator 64 to rotate, thereby driving the generator 64 to generate electricity. By connecting the generator 64 to a power storage device, the generated high-temperature steam can be converted into electrical energy for use, so as to reduce production costs. Moreover, the centralized discharge of the high-temperature steam from the exhaust pipe 66 can effectively prevent the high-temperature steam from scalding the staff.

[0050] During operation, currently, in addition to natural cooling, the Acheson furnace also uses a cooling device to cool the furnace body. It sprays water mist through the arranged atomizing nozzles during the movement on the furnace body to achieve the cooling effect. However, this cooling method has a slow cooling speed when in use, and cannot cool the inside of the furnace body, resulting in poor cooling effect. At the same time, the water mist sprayed on the high-temperature furnace body will generate high-temperature steam, and the high-temperature steam is likely to scald the operators, resulting in poor use safety. In this solution, the crucibles 12 loaded with materials are arranged in an array in the furnace body 11. Subsequently, slag is filled onto the crucibles 12 in the array. After the slag is filled, two heat preservation plates 21 are lifted and placed in the opening of the furnace body 11, and the insertion plates 26 below the heat preservation plates 21 are inserted into the slag between the crucibles 12 in the array. Subsequently, slag is laid on the two crucibles 12 again, and the first overhead plate 22 and the second overhead plate 23 are successively lifted and placed. Slag is also laid when the first overhead plate 22 and the second overhead plate 23 are stacked. Finally, after the second overhead plate 23 is lifted and placed, slag is laid on the second overhead plate 23 again. Subsequently, the inside of the furnace body 11 can be heated and raised in temperature.

[0051] When the heating is completed and the temperature starts to drop, the four inner tubes 214 are respectively pulled out from the positioning tubes 212 and connected to the liquid inlet 24 and the liquid outlet 25 on the sides of the two heat preservation plates 21. Then, the first valve 47 is opened to transport the tin liquid in the heat preservation tank 41 to two of the positioning tubes 212 through the tin delivery tube 42, and through the inner tubes 214 in the positioning tubes 212 and the liquid inlets 24 connected thereto, it is respectively transported into the connecting channels 27 in the two heat preservation plates 21. After the tin liquid enters the connecting channels 27, it will flow into the U-shaped channels 28 provided in the plurality of plug boards 26 along the set routes respectively to take away the high temperature between and above the plurality of crucibles 12. Then, the tin liquid will be discharged through the liquid outlet 25, the other two inner tubes 214 and the positioning tubes 212 and flow back into the heat preservation tank 41 through the tin return tube 44. When transporting the tin liquid, the second overhead plate 23 and the first overhead plate 22 can be lifted successively according to the process requirements and the actual temperature to achieve the effect of layered temperature reduction and improve the temperature reduction speed of the furnace body 11. When transporting the tin liquid, the second valve 56 can be opened and the liquid inlet 35 can be closed, and the coolant in the liquid storage tank 51 is transported into the housing 52 by using the water pump 54 to cool the high-temperature tin liquid flowing back in the tin return tube 44 to improve the temperature reduction effect of the tin liquid circulating into the heat preservation plates 21;

[0052] When the circulating temperature of the tin liquid cannot reduce the temperature in the furnace body 11, all the tin liquid is recycled into the heat preservation tank 41 and the first valve 47 is closed. Then, the four first sealing rings 213 are disconnected from the liquid inlet 24 and the liquid outlet 25 on the sides of the two heat preservation plates 21. Subsequently, the two heat preservation plates 21 are lifted from the furnace body 11 to improve the heat dissipation effect of the furnace body 11. Then, the lock 38 is unlocked to open the heat preservation cover 37 from the outside of the installation groove 31. After the heat preservation cover 37 is opened, the heat dissipation fins 33 will be directly exposed to increase the heat dissipation area of the furnace body 11 through the heat dissipation fins 33 and improve the heat dissipation effect. The liquid inlet 35 is opened and the second valve 56 is closed, so that the coolant in the liquid storage tank 51 is transported into the cooling tube 34 through the liquid inlet 35 by using the water pump 54. Under the action of the coolant circulating in the cooling tube 34, the temperature of the furnace body 11 is further reduced. Then, the circulating coolant will flow back into the liquid storage tank 51 through the liquid discharge port 36 and the water return pipe 58;

[0053] When the coolant forms steam due to high temperature when entering the housing 52 and the cooling tube 34, the high-temperature steam will move upward and enter the steam chamber 61 through the pressure relief pipe 62 connected to its pipeline. When the high-temperature steam enters the steam chamber 61, it will be quickly sprayed on the blades 65 through the nozzle 63, so that the blades 65 drive the generator 64 to operate and generate electricity. By connecting the generator 64 to the power storage device to store the generated electric energy, the production cost can be reduced, and finally the high-temperature steam will be discharged outdoors through the exhaust pipe 66 to avoid scalding the staff by the high-temperature steam;

[0054] The cooperation achieves the effect of layered cooling, and can cool the inside of the furnace body. Compared with the traditional Acheson furnace cooling device, it has a better cooling effect, a faster cooling speed, can avoid scalding workers by high-temperature steam, and ensure the safety of workers.

[0055] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
