Description

Technical Field

[0001] The utility model relates to the technical field of graphitization furnaces, in particular to a graphitization furnace with an automatic ignition device. Background Art

[0002] A graphitization furnace is a high-temperature treatment equipment for the sintering and graphitization of carbon materials, the graphitization of PI films, the graphitization of heat-conducting materials, the sintering of carbon fiber ropes, the sintering and graphitization of carbon fiber filaments, the purification of graphite powder, and other materials that can be graphitized in a carbon environment. With the improvement of national environmental protection emission standards, during the graphitization process of anode materials, raw materials such as petroleum coke and needle coke need to be added.

[0003] During the electric heating process, the volatile components (volatile ingredients) generated in the graphitization furnace are mostly harmful gases such as carbon monoxide, sulfur dioxide, and sulfides that have not fully reacted with oxygen. Therefore, it will pollute the environment. During the treatment process, when there is generally a spill of volatile substances, the manual ignition method is adopted to make harmful gases such as carbon monoxide fully react with oxygen to form harmless gases and then be discharged or collected.

[0004] However, due to the large-scale of the graphitization furnace, when there is gas volatilization and spillage on the existing furnace surface, the diffusion range is large and it cannot be concentrated. The manual ignition is difficult and the operation is highly dangerous, which does not meet the safety production standards. Therefore, it is necessary to design an automatic ignition device to achieve a fully automatic ignition operation. Content of the Utility Model

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, this embodiment provides a graphitization furnace with an automatic ignition device. The graphitization furnace with an automatic ignition device includes a furnace body 1, and a plurality of ventilation holes 2 are uniformly arranged on the furnace body 1. It is characterized in that an ignition mechanism for high-temperature oxidation of the gas discharged from the ventilation holes 2 is provided at the ventilation holes 2 of the furnace body 1.

[0024] Compared with the prior art, by automatically igniting the gas discharged from the ventilation holes 2, first, the discharged gas can be fully oxidized, reducing pollution emissions while meeting the safety production standards and reducing the harm to the environment. Second, it also solves the problems of difficult manual ignition and high operation risk, and improves the overall safety of the equipment during use.

[0025] As Figures 1-2As shown, in one embodiment, a lead screw 5, a threaded block 6 threadedly connected to the lead screw 5, and a driving mechanism for driving the lead screw 5 to rotate are provided on the furnace body 1. Two sets of threads with opposite helix directions are provided on the lead screw 5. The two sets of threads, the ignition mechanism, and the threaded block 6 are all symmetrically arranged with respect to the central cross-section of the furnace body 1. A first guiding groove 4 is formed on the furnace body 1 in the same direction as the arrangement direction of the air-permeating holes 2. The threaded block 6 is slidably fitted in the first guiding groove 4. The axial direction of the lead screw 5 is the same as the extending direction of the first guiding groove 4. The ignition mechanism is installed on the threaded block 6 so that when the driving mechanism is started, the ignition mechanism can be linked and high temperature can be applied to the air outlets of a plurality of air-permeating holes 2 on the moving route of the ignition mechanism in sequence.

[0026] In an embodiment of the present utility model, the driving mechanism is composed of a motor 12 fixedly installed on the heat insulation plate 10, a first belt pulley 13 fixedly installed at the power end of the motor 12, and a second belt pulley 14 fixedly installed at one end of the lead screw 5. The first belt pulley 13 and the second belt pulley 14 are connected by a belt. The ignition mechanism selects an igniter 8.

[0027] Specifically, by controlling the motor 12 to drive the first belt pulley 13 to rotate, the first belt pulley 13 drives the second belt pulley 14 to rotate under the action of the belt, and the second belt pulley 14 drives the lead screw 5 to rotate accordingly. Since the lead screw 5 is threadedly connected to the threaded block 6, the threaded block 6 can be moved along the extending direction of the first guiding groove 4, thereby driving the igniter 8 on the threaded block 6 to apply high temperature to the air outlets of a plurality of air-permeating holes 2 on the moving route at one time, completing the high-temperature oxidation treatment of the gas. By providing two sets of threads with opposite helix directions on the lead screw 5, the traveling path of the igniter 8 can be shortened, and the ignition efficiency can be further improved.

[0028] As Figures 1-2 shown, in one embodiment, it further includes: a heat insulation plate 10, a water storage tank 11, a water pump, a cooling tank 7, a water inlet pipe 15, and a water outlet pipe 16. The heat insulation plate 10, the water storage tank 11, the water pump, the cooling tank 7, the water inlet pipe 15, and the water outlet pipe 16 are also symmetrically arranged with respect to the central cross-section of the furnace body 1. The heat insulation plate 10 is fixedly installed on the furnace body 1. The water storage tank 11 is fixedly installed on the heat insulation plate 10. The cooling tank 7 is fixedly installed on the threaded block 6 and a water outlet pipe 16 is connected to the cooling tank 7. The water storage tank 11 and the cooling tank 7 are connected by a water inlet pipe 15, and a water pump is connected to the water inlet pipe 15.

[0029] Since the igniter 8 contains electrical wires and cables inside, high temperatures can damage the igniter 8. When the temperature of the igniter 8 reaches the dangerous range, the water pump is started to inject cooling water from the water storage tank 11 into the cooling box 7 through the water inlet pipe 15. By cooling the cooling box 7, the temperature of the igniter 8 is reduced, which is beneficial to protecting the igniter 8. After the water in the cooling box 7 cools the igniter 8, its temperature rises. The hot water in the cooling box 7 can be discharged through the outlet pipe 16 to receive new cooling water. By installing heat insulation plates 10 for each component, heat insulation protection can be provided for each component on the heat insulation plates 10.

[0030] As Figures 1-2 shown, in one embodiment, a temperature sensor 9 is fixedly installed on the ignition mechanism, and a control panel 3 is fixedly installed on the furnace body 1. The temperature sensor 9 is electrically connected to the control panel 3.

[0031] By providing a temperature sensor 9 on the igniter 8, the temperature sensor 9 can accurately detect the temperature of the igniter 8 and transmit a signal to the control panel 3. The control panel 3 controls the opening of the water inlet pipe 15, so that the cooling water in the water storage tank 11 enters the cooling box through the water inlet pipe 15 to cool the igniter 8. The water whose temperature has risen after cooling is discharged from the cooling box 7 by opening the outlet pipe 16, and the cooling box 7 can receive new cooling water.

[0032] As Figure 1 shown, in one embodiment, a flue gas hood covering all the ventilation holes 2 is installed on the furnace body 1. The flue gas hood is connected to the desulfurization tower through a pipeline.

[0033] In order to facilitate the collection of the gas after high-temperature oxidation treatment, after the gas is subjected to high-temperature oxidation by the igniter 8, it is collected through the flue gas hood and sent to the interior of the desulfurization tower through the pipeline connected to the flue gas hood, which can realize the collection of harmful gases and protect the atmospheric environment.

[0034] As Figures 2-5 shown, in one embodiment, the ignition mechanism is detachably installed on the cooling box 7.

[0035] By realizing the installation and disassembly of the igniter 8, the flexibility of the igniter 8 can be effectively enhanced. On the one hand, different models of igniters 8 can be selected according to different required temperatures. On the other hand, when the technology is upgraded and improved, and when the igniter 8 is improved or new functions are added, it is convenient to install and disassemble the igniter 8.

[0036] As Figures 2-5As shown, in one embodiment, the cooling box 7 is provided with an adjusting mechanism. The cooling box 7 is provided with a slot 18, and the ignition mechanism is provided with a plug rod 26 that can be adaptively inserted into the slot 18. The operation of the adjusting mechanism can lock the plug rod 26 in the slot 18.

[0037] Overall, by controlling the operation of the adjusting mechanism, the plug rod 26 can be adaptively inserted into the slot 18 on the cooling box 7, realizing the installation and disassembly of the igniter 8. By realizing the installation and disassembly of the igniter 8, the flexibility of the igniter 8 can be effectively enhanced. On the one hand, different models of igniters 8 can be selected according to different required temperatures. On the other hand, when the technology is upgraded and advanced, and the igniter 8 is improved or new functions are added, it is convenient to install and disassemble the igniter 8.

[0038] As Figures 2-5 shown, in one embodiment, the adjusting mechanism specifically includes: a turntable rotatably installed on the cooling box 7 and a driving device. The turntable is provided with a slot 18, and the turntable is also provided with a second guiding groove 22. A ejector rod arranged along the radial direction of the turntable is movably installed on the turntable. The ejector rod can move relative to the turntable along the radial direction of the turntable. One end of the ejector rod is installed with a guiding shaft 25 that is adaptively inserted into the second guiding groove 22. When the driving device drives the turntable to rotate in one direction, the wall of the second guiding groove 22 can drive the ejector rod to enter the slot 18 along the radial direction of the turntable by pushing the guiding shaft 25 and be stuck in the slot 27 on the outer wall of the plug rod 26 in the slot 18.

[0039] In the embodiment of the present utility model, the driving device is composed of an electromagnetic slide rail 19 fixedly installed on the cooling box 7, an electromagnetic slider 20 sliding along the track of the electromagnetic slide rail 19, and a rack 21 fixedly installed on the electromagnetic slider 20. The turntable is selected as a gear 17 that meshes with the rack 21. The ejector rod includes a supporting block 23 fixedly installed on the gear 17 and a clamping rod 24 slidably installed on the supporting block 23.

[0040] Specifically, when the igniter 8 needs to be installed, the insertion rod 26 at the bottom of the igniter 8 is inserted into the slot 18 opened on the gear 17 and the latch rod 24 is aligned with the card slot 27. The electromagnetic slider 20 slides along the track of the electromagnetic slide rail 19 under the magnetic field force of the electromagnetic slide rail 19 and drives the rack 21 to move. Through the movement of the rack 21, the meshing transmission between the rack 21 and the gear 17 is realized, and then the gear 17 rotates in one direction. During the counterclockwise rotation of the gear 17, the second guiding groove 22 pushes the guiding shaft 25 to drive the latch rod 24 on the support block 23 to move radially along the gear 17, so that a plurality of latch rods 24 synchronously enter the inside of the card slot 27 to realize the fixed installation of the igniter 8. When the igniter 8 needs to be disassembled, only by controlling the rotation of the gear 17 in the other direction through the movement of the rack 21 can a plurality of latch rods 24 be simultaneously withdrawn from the inside of the card slot 27, thereby completing the disassembly of the igniter 8. By realizing the installation and disassembly of the igniter 8, the flexibility of the igniter 8 can be effectively enhanced. On the one hand, different models of igniters 8 can be selected according to different required temperatures. On the other hand, with the upgrading and progress of technology, when the igniter 8 is improved or new functions are added, it is convenient to install and disassemble the igniter 8.
