Description

Technical Field

[0001] The invention belongs to the technical field of graphite felt, and in particular relates to a production and processing technology of graphite felt. Background Art

[0002] Graphite felt is obtained by treating carbon felt at a temperature above 2000°C in a vacuum or inert atmosphere. Its carbon content is higher than that of carbon felt, reaching more than 99%. It has good thermal insulation, heat insulation and electrical conductivity properties and is widely used in the industrial field.

[0003] In the existing processing of graphite felt, the carbon felt rolled into a tube will be heated unevenly, affecting the quality of graphite felt production, and the felt body is mostly loaded and unloaded manually, which is too troublesome. At the same time, a large amount of waste gas will be generated when the graphite felt is heated. These waste gases will cause serious pollution to the operating space and environment, and endanger people's health. After the graphite felt is formed, a lot of burrs and dust will be generated. If not processed, it will affect the smoothness of the graphite felt surface. For this reason, we propose a graphite felt production and processing technology. Summary of the invention

[0004] The purpose of the present invention is to provide a graphite felt production and processing technology to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a graphite felt production and processing process, specifically comprising the following steps:

[0006] 1. A graphite felt production and processing process, comprising, characterized in that: specifically comprising the following steps:

[0007] S1. According to the length of the felt core, the electric slide is slid in the slide rail to limit the length of the felt core. The threaded rod is driven to rotate by the fourth motor to shrink the clamping plate to fix the felt core. When the carbon felt is loaded and graphitized, the third motor drives the rotating shaft to rotate to unwind the carbon felt. At the same time, the first motor drives the rotating rod to rotate. The rotating rod drives the carbon felt to be rolled up between the cover plate and the limit plate. When the carbon felt is rolled up, the carbon felt is rolled up along the winding limit ring so that there is a gap between the carbon felts.

[0008] S2. After the carbon felt is rolled up, the cover plate and the carbon felt are driven to be retracted into the graphitization furnace by the first servo electric cylinder, and the air in the graphitization furnace is extracted by the vacuum pump to make the inside of the graphitization furnace in a vacuum state, and at the same time, an inert gas is introduced into the inside. At this time, the electromagnetic induction coil works to generate a magnetic field, so that the metal tube heats up, and then the carbon felt in the graphitization furnace is heated, and the first gear is driven to rotate by the second motor, and the first gear rotates, driving the gear ring to rotate, and the gear ring drives the graphitization furnace to rotate;

[0009] S3. When the graphitization of the carbon felt is completed, the graphitization furnace is cooled and the inert gas is extracted. The inert gas and high-temperature gas in the graphitization furnace are discharged into the U-shaped water pipe through the gas control valve. The cold water in the water tank cools the gas in the U-shaped water pipe. At the same time, the water in the water tank is also heated by the high-temperature gas to be gasified. The gasified water vapor enters the heat exchanger in the insulation box through the connecting pipe and is stored in the insulation box. When the carbon felt is heated next time, it is discharged into the graphitization furnace through the fan and the gas control valve. The cooled gas in the U-shaped water pipe is discharged into the gas purification component through the connecting pipe. The gas purification component adsorbs and removes the dust, sulfur-containing impurities, and nitrogen-containing impurities generated by the deepening of the high-temperature treatment of the raw material felt, and purifies the inert gas. When the graphitization furnace needs to be filled with inert gas again, the purified inert gas is discharged into the graphitization furnace;

The removed dust and burrs are collected by a vacuum cleaner, and then the two limit plates are driven to move by the third servo electric cylinder on the surface of the two support plates to limit the movement of the graphite felt.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This graphite felt production and processing technology can make the carbon felt roll up along the limit ring through the cooperation of the cover plate, the rotating rod, the clamping assembly, the limit plate and the limit ring, so that the carbon felt is rolled up along the limit ring, so that there is a distance between the carbon felts, so that the carbon felt can be heated more evenly when it is heated. The second motor can drive the first gear to rotate, and the rotation of the first gear can drive the gear ring to rotate. The rotation of the gear ring can drive the graphitization furnace to rotate, so that the heating direction of the carbon felt by the graphitization furnace is no longer single, thereby making the carbon felt in the graphitization furnace heated more evenly.

[0019] (2) In the production and processing technology of graphite felt, when the carbon felt is loaded and graphitized, the third motor drives the rotating shaft to rotate, thereby unwinding the carbon felt, and at the same time the first motor drives the rotating rod to rotate. The rotation of the rotating rod can drive the carbon felt to be rolled up between the cover plate and the limit plate, so as to facilitate the loading and unloading of the felt body. At the same time, the loading mechanism can be fixed according to the length and size of the felt body core, so that the electric slide slides in the slide rail and adjusts the length of the felt body core to limit the position. The fourth motor can drive the threaded rod to rotate. The threaded rod has the middle as the dividing line, and the threads at both ends are in opposite directions. When the threaded rod rotates, the clamping plate can be simultaneously contracted to fix the felt body core, so as to facilitate the loading and unloading of the felt body.

[0020] (3) In the production and processing technology of graphite felt, the surface of the graphite felt can be processed by a cleaning mechanism. The second servo electric cylinder drives the connecting frame to approach the graphite felt, and then the fifth motor drives the dust removal roller to rotate to remove dust and burrs on the surface of the graphite felt. The removed dust and burrs can be collected by a vacuum cleaner, thereby making the surface of the graphite felt smoother and improving the production quality of the graphite felt. At the same time, the third servo electric cylinder on the surface of the two support plates drives the two limit plates to move, thereby limiting the movement of the graphite felt and preventing the graphite felt from being deviated during movement, which is beneficial to the unloading and winding of the graphite felt.

[0021] (4) In the production and processing technology of graphite felt, after the graphitization of the carbon felt is completed, the graphitization furnace needs to be cooled and the inert gas needs to be extracted. The inert gas and high-temperature gas in the graphitization furnace can be discharged into the U-shaped water pipe through the gas control valve. The cold water in the water tank can cool the gas in the U-shaped water pipe. At the same time, the water in the water tank is also heated by the high-temperature gas to be gasified. The gasified water vapor will pass through the connecting pipe to the heat exchanger in the insulation box and be stored in the insulation box. When the carbon felt is heated next time, it will be discharged into the graphitization furnace through the fan and the gas control valve. This method is not only conducive to cooling the graphitization furnace, but also can partially recover the heat, saving energy loss. The cooled gas in the U-shaped water pipe can be discharged into the gas purification component through the connecting pipe. The inert gas is purified by the gas purification component. When the graphitization furnace needs to be filled with inert gas again, the purified inert gas can be discharged into the graphitization furnace, thereby ensuring the recyclability of the inert gas.

Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0041] See also Figure 1 As shown, a graphite felt production and processing technology, based on graphite felt processing equipment, specifically includes:

[0042] S1. Using graphite felt processing equipment, according to the length of the felt core, the electric slide 23 is slid in the slide rail 22 to adjust the length of the felt core, and the fourth motor 28 can drive the threaded rod 29 to rotate. The threaded rod 29 is divided by the middle, and the threads at both ends are in opposite directions. When the threaded rod 29 rotates, the clamping plate 210 can be simultaneously contracted to fix the felt core. When the carbon felt is loaded and graphitized, the third motor 2 The first motor 16 drives the rotating shaft 26 to rotate, thereby unwinding the carbon felt.

The surfaces of the cover plate 15 and the limiting plate 19 are both provided with a rolling limit ring 110. When the carbon felt is rolled up, the carbon felt will be rolled up along the rolling limit ring 110, so that there is a distance between the carbon felts, so that the carbon felts can be heated more evenly when being heated.

[0043] S2. After the carbon felt is rolled up, the cover plate 15 and the carbon felt are driven to be retracted into the graphitization furnace 12 by the first servo electric cylinder 13, and the air in the graphitization furnace 12 is extracted by the vacuum pump to make the inside of the graphitization furnace 12 in a vacuum state, and at the same time, an inert gas is introduced into the inside. At this time, the electromagnetic induction coil works to generate a magnetic field, so that the metal tube 1202 is heated, and then the carbon felt in the graphitization furnace 12 is heated. The second motor 113 is driven to rotate the first gear 114, and the first gear 114 rotates, which can drive the gear ring 115 to rotate. The gear ring 115 rotates, which can drive the graphitization furnace 12 to rotate, so that the carbon felt in the graphitization furnace 12 is heated more evenly;

[0044] S3. After the graphitization of the carbon felt is completed, the graphitization furnace 12 needs to be cooled down and the inert gas needs to be extracted. The inert gas and the high-temperature gas in the graphitization furnace 12 can be discharged into the U-shaped water pipe 43 through the gas control valve 41. The U-shaped water pipe 43 is arranged in the water tank 42. The cold water in the water tank 42 can cool down the gas in the U-shaped water pipe 43.

The gasified water vapor will pass through the connecting pipe to the heat exchanger in the insulation box 45, and will be stored in the insulation box 45 for heating the carbon felt next time. When the inert gas is discharged into the graphitization furnace 12 through the fan 46 and the gas control valve 41, the gas in the U-shaped water pipe 43 that has been cooled can be discharged into the gas purification component 44 through the connecting pipe. The gas purification component 44 includes an active adsorption layer, a metal reaction layer, and a wet reaction solution layer, and then adsorbs and removes dust, sulfur-containing impurities, and nitrogen-containing impurities generated as the raw material felt is treated at high temperature, thereby purifying the inert gas. When the graphitization furnace 12 needs to be filled with inert gas again, the purified inert gas can be discharged into the graphitization furnace 12, thereby ensuring the recycling of the inert gas.

[0045] S4. When the carbon felt is graphitized and becomes graphite felt, the surface of the graphite felt is processed by the cleaning mechanism 30, and the connecting frame 34 is driven to approach the graphite felt by the second servo electric cylinder 33, and then the dust removal roller 38 is driven to rotate by the fifth motor 35 to remove dust and burrs from the surface of the graphite felt. The removed dust and burrs are collected by the vacuum cleaner 312, and the third servo electric cylinder 310 on the surface of the two support plates 39 drives the two limit plates 311 to move, so as to limit the movement of the graphite felt to prevent the graphite felt from being displaced during movement, thereby affecting the winding and unloading of the graphite felt, and finally the cleaned graphite felt is wound and unloaded by the feeding mechanism 20.

When the graphitization of the carbon felt is completed, the graphitization furnace 12 needs to be cooled down and the inert gas needs to be extracted. The inert gas and the high-temperature gas in the graphitization furnace 12 can be discharged into the U-shaped water pipe 43 through the gas control valve 41. The U-shaped water pipe 43 is arranged in the water tank 42. The cold water in the water tank 42 can cool down the gas in the U-shaped water pipe 43. At the same time, the water in the water tank 42 is also heated by the high-temperature gas to be gasified. The gasified water vapor will pass through the connecting pipe to the heat exchanger in the insulation box 45, and will be stored in the insulation box 45. When the carbon felt is heated next time, it will be discharged through the fan 46 and the gas control valve. 41 is discharged into the graphitization furnace 12. This method is not only conducive to cooling the graphitization furnace 12, but also can partially recover heat, saving energy loss. The cooled gas in the U-shaped water pipe 43 can be discharged into the gas purification component 44 through the connecting pipe. The gas purification component 44 includes an active adsorption layer, a metal reaction layer, and a wet reaction solution layer, and then adsorbs and removes dust, sulfur-containing impurities, and nitrogen-containing impurities generated by deepening the high-temperature treatment of the raw material felt, thereby achieving purification of the inert gas. This is a prior art. The inert gas is purified by the gas purification component 44. When the graphitization furnace 12 needs to be filled with inert gas again, the purified inert gas can be discharged into the graphitization furnace 12, thereby ensuring the recyclability of the inert gas.
