[0003] At present, the method for preparing graphite felt electrodes is: intermittent production in a high-temperature furnace. After the carbon fiber filaments enter the intermittent furnace, they are heated up-cooled to room temperature-heated up-cooled to room temperature several times to form carbonized filaments, and then the filaments are woven into a felt structure through a needle punching machine.

[0004] Although the existing can-type carbonization furnace can realize the production of graphite felt electrodes, each production of a furnace requires multiple heating and waiting for cooling, which results in low thermal efficiency and production efficiency but high energy consumption.

[0018] The reciprocating drive group includes a round cam load wheel and an elliptical ring frame;

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0041] like Figure 1 As shown in FIG. 2 , the present invention provides a carbonization device for producing graphite felt electrodes, comprising a cabinet furnace body 1 and a cabinet roller frame 2, wherein the cabinet roller frame 2 is arranged in front of the cabinet furnace body 1;

[0042] Several independent heating compartments 11 are sequentially arranged in the cabinet furnace body 1 along the height direction, and each heating compartment 11 can heat the wire separately. A wire inlet and a wire outlet are constructed at one end of each heating compartment 11 facing the cabinet roller frame 2. The heating compartments 11 are independent of each other, and the wire in and out are realized through the wire inlet and the wire outlet. Rollers 3 are arranged in each heating compartment 11 and on the cabinet roller frame 2 corresponding to the heating compartment 11. A wire unwinder and a wire take-up are arranged on the outside of the cabinet furnace body 1 and the cabinet roller frame 2. In this embodiment, an electric drive take-up device is used, and two sets of electric drive take-ups are used as driving sources for the movement of the wire unwinding and unwinding.

[0043] When winding the wire, the wire is wound around the lowest roller 3 in the cabinet roller frame 2, enters the winding roller 3 from the wire inlet of the lowest heating compartment 11 in the cabinet furnace body 1, and is led out from the wire outlet of the heating compartment 11, and then is wound around the roller 3 adjacent to the lowest roller in the cabinet roller frame 2. The above process is repeated, so that the moving trajectory of the wire is continuously rising, and is wound in a continuous S shape in the cabinet roller frame 2 and the heating compartment 11 of the cabinet furnace body 1;

[0044] During high-temperature carbonization, when each heating compartment 11 reaches the threshold temperature, the unwinder and the take-up are started, and the wire moves from the wire outlet to the outside to enter the room temperature environment after passing through a heating compartment 11, and then enters the next heating compartment 11 for heating through the steering action of the cabinet roller frame. During this process, each heating compartment 11 only needs to maintain the threshold temperature. As the wire moves, the above process is repeated, and then the carbonization process of heating up-cooling to room temperature-heating-cooling to room temperature is realized several times without stopping the movement of the wire and without waiting for the furnace body to cool down. Such a design improves the utilization of thermal efficiency and production efficiency, and also reduces energy consumption.

[0045] Furthermore, considering that a large amount of tar and ash impurities will be generated during the high-temperature carbonization process, some of these impurities will adhere to the wire. If they are not handled in time, during the repeated rolling of the roller 3 and the process of heating and cooling, the tar and ash impurities will solidify on the wire, and with the subsequent winding and needle punching processes, they will be wrapped in the graphite felt, thereby seriously affecting the quality of the graphite felt and reducing the service life of the graphite felt.

[0046] Therefore, the carbonization equipment also includes an external insulation mechanism installed above the outlet of the cabinet furnace body 1. The wire coming out of the tar outlet is insulated by the external insulation mechanism. On the one hand, it can avoid the tar solidifying when it encounters cold due to a sudden drop in temperature, which is convenient for subsequent scraping. On the other hand, it can avoid the large internal stress caused by a sudden drop in the wire temperature.

[0047] like Figure 2 As shown in FIG6 , specifically, the external heat preservation mechanism includes a plurality of electric heating plates 41 and a centralized and distributed flip drive group;

[0048] The gathering and dispersing flipping drive group is used to drive a plurality of electric heating plates 41 to disperse or gather along the lateral direction of the cabinet furnace body 1, so that it can adapt to the high-temperature carbonization treatment of wire groups of different widths, and increase or decrease the heating area according to the overall width of the wire group. The wire group is composed of a plurality of strands of wire, and the width of the wire group is the overall width of the plurality of strands of wire on the roller 3;

[0049] In addition, the centralized and distributed flipping drive group can also synchronously drive the electric heating plate 41 to flip clockwise or counterclockwise along the horizontal direction of the cabinet furnace body 1, and then change the vertical spacing between the electric heating plate 41 and the wire group by adjusting the angle, so as to adjust the range of heat radiation corresponding to the wire groups of different widths, so as to avoid insufficient cooling time of the wire due to excessively high temperature or tar solidification due to excessively low temperature;

[0050] Specifically, the collecting and distributing flip driving group includes: a plurality of groups of parallelly arranged conveyor belts 51, the wheel diameters of the pulleys 52 at the ends of the conveyor belts 51 decrease or increase in sequence along the arrangement sequence of the conveyor belts 51, and are connected to the output end of the rotary driver through a synchronous shaft 53, two electric heating plates 41 are arranged on each group of conveyor belts 51, one of the electric heating plates 41 is connected to the conveyor belt 51 above the pulley 52 through an electric heating plate mounting frame 42, and the other electric heating plate 41 is connected to the conveyor belt 51 below the pulley 52 through another electric heating plate mounting frame 42, because when the conveyor belt 51 is running, the conveyor belts 51 above and below the pulley 52 move in opposite directions, and then the electric heating plate mounting frames 42 are moved toward or away from each other through the positive or reverse rotation of the pulley 52;

[0051] In this embodiment, six groups of electric heating plate mounting frames 42 are provided, the two outermost groups are mounted on the conveyor belt 51 with the largest diameter of the pulley 52, the two middle groups are mounted on the conveyor belt 51 with the medium diameter of the pulley 52, and the two innermost groups are mounted on the conveyor belt 51 with the smallest diameter of the pulley 52;

[0052] When the rotary drive rotates forward, each conveyor belt 51 drives its corresponding electric heating plate mounting frame 42 to move in opposite directions. Since the wheel diameters of the pulleys 52 are different, the linear speeds of the corresponding conveyor belts 51 are also different, so the gaps between adjacent electric heating plate mounting frames 42 are continuously expanded, thereby realizing the lateral dispersion of the electric heating plates 41. Similarly, when the rotary drive rotates reversely, the corresponding electric heating plates 41 on each conveyor belt 51 are synchronously retracted, and the gaps between adjacent electric heating plate mounting frames 42 are continuously reduced, thereby realizing the lateral aggregation of the electric heating plates 41.

[0053] Specifically, the electric heating plate 41 is fixedly mounted on the rotating frame 44, the electric heating plate mounting frame 42 is rotatably connected to the rotating frame 44 via a horizontal rotating shaft 43, and a vertical rotating shaft 45 is vertically mounted on the electric heating plate mounting frame 42 above the rotating frame 44 via a seat bearing. On the horizontal rotating shaft 43 and the vertical rotating shaft 45, corresponding fixed sleeves are provided with bevel gears I46 and bevel gears II47, and the bevel gear I46 is meshedly connected to the bevel gear II47;

[0054] The end of the synchronization shaft 53 is rotatably connected in the shell frame 54 through a seat bearing. The shell frame 54 is used as a support body and is fixedly connected to the outside of the cabinet furnace body 1. A rack 55 is fixedly installed on the inner cavity side of the shell frame 54, and a gear 48 meshing with the rack 55 is also fixedly mounted on the vertical shaft 45; thereby, the electric heating plate mounting frame 42 is driven to rotate through the rack 55 during the movement with the conveyor belt 51. The rotation of the gear 48 drives the vertical shaft 45 to rotate at the same time. The vertical shaft 45 drives the horizontal shaft 43 to rotate through the bevel gear II47 and the bevel gear I46. The horizontal shaft 43 is fixedly connected to the electric heating plate mounting frame 42 and synchronously drives the electric heating plate mounting frame 42 to rotate, thereby realizing the angle adjustment of the electric heating plate 41 relative to the electric heating plate mounting frame 42.

[0055] like Figure 7 As shown in FIG8 , specifically, the carbonization equipment further includes a reciprocating wire scraping mechanism;

[0056] The reciprocating scraping mechanism includes a scraper 71 and a reciprocating drive group. The two groups of reciprocating drive groups are arranged on both sides of the two groups of scrapers 71. The two groups of scrapers 71 are respectively constructed above and below the outlet of the cabinet furnace body 1. The reciprocating drive group can synchronously drive the two groups of scrapers 71 to move back and forth along the direction of the outlet under the drive of the roller 3 in the cabinet roller frame 2. The moving path of the scraper 71 is located within the heat radiation range of the electric heating plate 41, and then the wire is scraped synchronously from the top and bottom of the wire group to remove tar and ash impurities attached to the wire.

[0057] Specifically, the reciprocating drive group includes a round cam wheel 62 and an elliptical ring frame 63;

[0058] The cam wheel 62 is connected to the roller 3 in the cabinet roller frame 2 through a synchronous belt 61. A cam 64 is constructed on the end side of the cam wheel 62. The cam 64 is sleeved in the elliptical ring frame 63. The cam wheel 62 and the elliptical ring frame 63 are designed to be coaxial in the horizontal direction. The head end and the tail end of the elliptical ring frame 63 are both connected to the extension arm 65 in the horizontal direction. The two ends of the scraper 71 are fixedly connected to the extension arm 65. The two groups of the extension arms 65 are sleeved on the guide tube 66. The guide tube 66 is an anti-detachment guide tube structure, that is, it can only reciprocate in the guide tube 66 but cannot be separated from the guide tube 66. The tail end of the guide tube 66 is fixed to the outside of the cabinet furnace body 1, and the two guide tubes 66 are fixedly connected in the vertical direction by a reinforcing rib column to increase stability. The support shaft 621 of the cam wheel 62 is rotatably connected to the support shaft carrier 67, and the tail end of the support shaft carrier 67 is fixed to the outside of the cabinet furnace body 1.

[0059] When the cam wheel 62 is driven to rotate, the cam 64 is driven to rotate. During the rotation, the cam 64 drives the elliptical ring frame 63 to move back and forth in the guide tube 66, and then drives the scraper 71 to move back and forth through the extension arm 65 to scrape the wire.

[0060] Specifically, the support shaft 621 and the corresponding roller 3 in the cabinet roller frame 2 are both equipped with a transmission wheel 68, and the synchronous belt 61 is mounted on the transmission wheel 68, and then the scraper 71 is synchronously driven to reciprocate through the roller 3 in the cabinet roller frame 2, that is, the scraper 71 starts and stops synchronously with the roller 3, so as to avoid the phenomenon of scraping omission, and there is no need to add an additional driving source and control unit; and during the entire reciprocating motion of the scraper 71, there must be a section of the stroke that is opposite to the moving direction of the wire, so as to achieve the stretching and scraping of the wire. On the one hand, it can bounce off the impurities remaining on the surface of the wire, and on the other hand, it can also separate the wires that are attached during the movement.

[0061] like Fig. 9 As shown, specifically, considering that a small amount of tar and ash impurities will stick to the scraper 71 during the repeated scraping process, which will reduce the scraping effect in the long run, the scraper 71 is designed to be a comb-shaped structure, and a plug plate 72 with the same comb-shaped structure is also provided on the moving path of the scraper 71. The tail end of the plug plate 72 is fixedly mounted on the outside of the cabinet furnace body 1 through a connecting foot. The plug plate 72 is arranged horizontally relative to the scraper 71, and the comb teeth of the two are staggered with each other, so as to be plugged into each other to achieve cleaning of the scraper 71.

[0062] Specifically, a U-shaped storage rack is also provided below the plug plate 72, and the tail end of the storage rack is also fixedly mounted on the outside of the cabinet furnace body 1 through a connecting foot. The storage rack is used to collect impurities that fall after the plug plate 72 and the scraper 71 are plugged in. The inner bottom surface of the storage rack is arranged in an inclined surface along the port, so that under the action of gravity, the impurities can slide in the storage rack to the port for discharge.

[0063] The working principle and working process of the present invention are as follows:

[0064] Before the high-temperature carbonization process, the spacing and flipping angle of the electric heating plates 41 are adjusted according to the overall width of the batch of wires on the roller 3. If the width is wide, when the rotary driver rotates in the forward direction, each conveyor belt 51 drives its corresponding electric heating plate mounting frame 42 to move in reverse. Since the wheel diameters of the pulleys 52 are different, the linear speeds of the corresponding conveyor belts 51 are also different, so the gaps between adjacent electric heating plate mounting frames 42 are continuously expanded, thereby realizing the lateral dispersion of the electric heating plates 41. Similarly, if the width is narrow, the rotary driver rotates in the reverse direction, so that the corresponding electric heating plates 41 on each conveyor belt 51 are synchronously retracted, and the adjacent electric heating plate mounting frames are The gap between the mounting frames 42 is continuously reduced, so that the electric heating plate 41 is gathered horizontally, and the heating area is adjusted in the width direction of the wire. At the same time, when the electric heating plate mounting frame 42 moves with the conveyor belt 51, it also drives the gear 48 to rotate through the rack 55. The gear 48 rotates and drives the vertical shaft 45 to rotate. The vertical shaft 45 drives the horizontal shaft 43 and the electric heating plate mounting frame 42 to rotate through the bevel gear II47 and the bevel gear I46, so that the angle of the electric heating plate 41 relative to the electric heating plate mounting frame 42 is adjusted, and the heat radiation range of the electric heating plate 41 is adjusted in the vertical direction of the wire.

[0065] During high-temperature carbonization, when each heating compartment 11 reaches the threshold temperature, the unwinder and the take-up are started, and the wire moves from the outlet to the outside to enter the room temperature environment after passing through a heating compartment 11, and then enters the next heating compartment 11 for heating through the steering effect of the cabinet roller frame. During this process, each heating compartment 11 only needs to maintain the threshold temperature. As the wire moves, the above process is repeated to achieve a carbonization process of heating up-cooling to room temperature-heating-cooling to room temperature for several times;

[0066] Every time the wire comes out of the tar outlet, the electric heating plate 41 keeps the wire in the radiation range warm, which can prevent the tar from solidifying when it is cold due to a sudden drop in temperature, making it easier to scrape it off, and can also prevent the wire from having a large internal stress due to a sudden drop in temperature.

[0067] The roller 3 in the cabinet roller frame 2 drives the cam wheel 62 to rotate through the synchronous belt 61, which in turn drives the cam 64 at the outer end of the cam wheel 62 to rotate. The cam 64 drives the elliptical ring frame 63 to move back and forth in the guide tube 66 during the rotation, so that the extended arm 65 of the elliptical ring frame 63 drives the scraper 71 to move back and forth above and below the wire to scrape the wire. During the movement of the scraper 71, the plug-in plate 72 will be continuously plugged in, thereby continuously cleaning the scraper 71.

[0068] The embodiments of the present invention are described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the present invention.
