Description

Technical Field

[0001] This invention relates to the field of electrode calcination technology, and in particular to a graphite electrode calcination apparatus and calcination method. Background Technology

[0002] The graphite electrode calcination device is a specialized thermal equipment that performs high-temperature heat treatment on graphite electrode green blanks under the protection of filler material, so that the coal tar binder is carbonized to form a stable carbon skeleton. Multiple materials can be placed at the same time during calcination to ensure processing efficiency.

[0003] For example, Chinese Patent Publication No. CN120313353B discloses a graphite electrode calcination device, belonging to the field of graphite electrode calcination technology. It includes a furnace body with a bottom plate on one side. Vertical plates are fixedly installed on both sides of the top of the bottom plate. Multiple sets of drive shafts and driven shafts are installed between the two vertical plates. Connecting shafts are fixedly installed at the ends of the drive shafts and driven shafts, passing through the vertical plates and rotatably engaging with them. A collar is rotatably fitted onto each drive shaft and driven shaft, and a top-pressing unit is provided on the outer wall of the collar. The drive shafts and driven shafts can drive the graphite electrode to rotate, thus facilitating uniform heating of the graphite electrode. Furthermore, the top-pressing unit, during the counterclockwise rotation of the drive shaft, can drive the top-pressing unit to deflect upwards to a horizontal state, thus facilitating the loading and unloading of the graphite electrode.

[0004] After roasting, the collar and top pressure unit can be rotated to a horizontal position to facilitate the feeding of the roasted material. During this process, the roasted material needs to move continuously along the drive shaft, driven shaft, collar and top pressure unit, which poses a risk of collision damage. At the same time, the drive shaft and driven shaft are relatively fixed based on the position of the vertical plate, which still makes it inconvenient to feed the material onto the drive shaft and driven shaft. It is subject to the structural limitations of the bottom plate and vertical plate, and has certain limitations in use.

[0005] Therefore, it is necessary to provide a graphite electrode calcination apparatus and calcination method to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a graphite electrode calcination apparatus and calcination method to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, a graphite electrode calcination device and calcination method are designed, in which the supporting component can support the material as it moves out from one side of the support. This facilitates the loading and unloading of the material relative to the supporting component, and the supporting component directly moves the material out without worrying about damage to the material after calcination.

[0008] Based on the above ideas, the present invention provides the following technical solution: a graphite electrode calcination device, including a support, a guide rail seat for sliding the support, and a furnace body corresponding to the support. The support is provided with a plurality of bases arranged in an array, and the bases are provided with support components for supporting materials. The support is provided with an adjustment component for driving all support components to rotate. After the support enters the furnace body along the guide rail, the starting adjustment component can drive the material to rotate in the furnace body through the support component; after the support returns to its original position along the guide rail, the starting adjustment component can drive all the bases to move out from one side of the support through the support component.

[0009] As a further aspect of the present invention: two horizontally adjacent bases are fixedly connected by a crossbar, and two vertically adjacent bases are fixedly connected by a vertical bar, and the inside of the bracket is provided with a sliding groove for the base to slide.

[0010] As a further aspect of the present invention: the support assembly includes a sleeve and two rollers rotatably mounted on the base, the sleeve and the two rollers rotating synchronously via belt drive, and the end of the sleeve being elastically connected to a shaft driven by an adjustment assembly via a first spring, the shaft being keyed to both the sleeve and the adjustment assembly.

[0011] As a further aspect of the present invention: the shaft includes a round rod, and two edges are fixedly installed on the outer surface of the round rod. The round rod rotates synchronously with the sleeve and the adjusting assembly through the edges.

[0012] As a further aspect of the present invention: a top rod corresponding to the position of the round rod is fixedly installed on the guide rail seat, the number of top rods is adapted to the number of round rods, and the diameter of the top rod is less than or equal to the diameter of the round rod.

[0013] As a further embodiment of the present invention: the adjustment assembly includes a motor fixedly mounted on a bracket and several driven wheels rotatably mounted on the bracket. The output shaft of the motor is fixedly mounted with a driving wheel that is connected to one of the driven wheels. A transmission belt is sleeved together among the several driven wheels, and the shaft and the corresponding driven wheel are connected to each other by a key shaft assembly to form a coaxial transmission.

[0014] As a further embodiment of the present invention: the surface of the transmission belt is elastically connected to a push rod by a second spring, and the surface of the base is slidably mounted with a protrusion corresponding to the edge position.

[0015] As a further aspect of the present invention: an arc edge is provided on the edge to movably fit the protrusion. When the edge moves along the axial direction of the sleeve, the arc edge can drive the protrusion to extend from the top of the base.

[0016] As a further aspect of the present invention: the number of push rods on the transmission belt is set to several, and the several push rods are arranged at equal intervals based on the transmission belt.

[0017] The present invention also provides the following technical solution: a graphite electrode calcination method, wherein the material is placed sequentially on the support assembly, and then the bracket moves along the guide rail to drive the support assembly and the material into the furnace for calcination. During this process, the adjustment assembly is activated to drive the material to rotate in the furnace through the support assembly; then the bracket is reset along the guide rail, and the adjustment assembly is activated to drive all the bases to move out from one side of the bracket through the support assembly.

[0018] Compared with the prior art, the beneficial effects of the present invention are: through the cooperation between the bracket, base, adjustment component and support component, the material can be driven to rotate in the furnace after entering the furnace, which helps to ensure uniform heating of the material, thereby ensuring the roasting effect of the material and the reliability of the overall quality.

[0019] After roasting is completed and the support is reset, all bases can be moved out from one side of the support. When they are moved out, the support components can move synchronously to maintain the support for the roasted material. At this time, the roasted material can be exposed from one side of the support. Therefore, the loading and unloading of the material is no longer restricted by the structure of the support, which can effectively improve the loading and unloading speed of the material. At the same time, the roasted material does not need to move along the support components or other structures, which can avoid collision damage between adjacent materials after roasting, and further ensure the overall roasting quality of the material.

[0022] Example 1: Please see Figures 1 to 8 This invention provides a graphite electrode calcination device, mainly used to achieve rapid loading and unloading of material 7 while ensuring calcination effect. The device includes a support 1, a guide rail seat 2 for horizontal reciprocating sliding of the support 1, and a furnace body 3 corresponding to the position of the support 1. The support 1 has an overall U-shaped design, and its interior is provided with a number of bases 4 arranged in an array. In this embodiment, there are six bases 4, and each of the six bases 4 is provided with a support component 5 for supporting material 7. When the support 1 moves along the guide rail seat 2 into the furnace body 3, the support component 5 can drive the material 7 to move synchronously into the furnace body 3, thereby completing the rapid calcination of material 7. The guide rail seat 2 and the furnace body 3 are existing mature technologies and will not be described in detail here.

[0023] Furthermore, such as Figure 1 As shown, the support 1 is equipped with an adjustment component 6 that is connected to all support components 5 in a transmission manner. When the support 1 drives the material 7 into the furnace body 3, the adjustment component 6 can be activated to drive the material 7 to rotate within the furnace body 3 through the support components 5, thereby ensuring the roasting effect of the material 7. When the support 1 is reset and corresponds to the guide rail seat 2, the transmission connection between the support components 5 and the adjustment component 6 can be released. At this time, the adjustment component 6 can be activated to drive the base 4, support components 5 and material 7 to move out from the left side of the support 1 through the support components 5.

[0024] In the above process, such as Figure 2As shown, when the base 4 moves out from one side of the bracket 1, the support component 5 can still support the material 7. At this time, the loading and unloading of the material 7 is not restricted by the structure of the bracket 1. The staff can quickly pick up and put down the material 7 of the support component 5 one by one from one side of the guide rail seat 2, or use external equipment to pick up and put down all the material 7 at the same time, which can effectively improve the loading and unloading speed of the material 7. On the other hand, it can avoid collision damage between adjacent materials 7. At the same time, the material 7 does not need to move continuously along the support component 5 after roasting, which can further ensure the overall processing quality of the material 7.

[0025] Reference Figure 3 In this embodiment, preferably, two horizontally adjacent bases 4 are fixedly connected by a horizontal bar 401, and two vertically adjacent bases 4 are fixedly connected by a vertical bar 402. At this time, there is one vertical bar 402 and several horizontal bars 401. The vertical bars 402, all horizontal bars 401 and all bases 4 are arranged in an I-shape, so that all bases 4 can move synchronously.

[0026] Furthermore, such as Figure 2 and Figure 3 As shown, the bracket 1 has a sliding groove 101 inside for the base 4 to slide. The sliding groove 101 can be a dovetail groove, which can ensure that the base 4 slides horizontally and prevent the base 4 from falling off the bracket 1.

[0027] Reference Figures 2 to 5 In this embodiment, preferably, the support assembly 5 includes a sleeve 503 and two rollers 502 rotatably mounted on the base 4. The sleeve 503 and the two rollers 502 rotate synchronously through a belt drive 506. The side of the sleeve 503 away from the furnace body 3 is elastically connected to a shaft 504 that is connected to the adjustment assembly 6 via a first spring 505. The shaft 504 is keyed to both the sleeve 503 and the adjustment assembly 6. The keyed assembly allows the shaft 504 to rotate synchronously with the sleeve 503, and the first spring 505 causes the shaft 504 to tend to extend out of the sleeve 503.

[0028] When the adjustment component 6 is started, the sleeve 503 is driven to rotate synchronously through the shaft 504 and the key shaft assembly. The sleeve 503 drives the two roller shafts 502 to rotate synchronously through the belt drive 506. When the two roller shafts 502 rotate, the placed material 7 can rotate on its own inside the furnace body 3, thereby ensuring the roasting effect of the material 7.

[0029] Specifically, such as Figure 5As shown, the shaft 504 includes a round rod 5041, and two edges 5042 are fixedly installed on the outer surface of the round rod 5041. The round rod 5041, together with the edges 5042, forms a key shaft assembly with the sleeve 503 and the adjusting assembly 6 in sync, thereby enabling the shaft 504 to rotate synchronously and move relative to the sleeve 503.

[0030] Correspondingly, such as Figure 2 and Figure 4 As shown, a top rod 501 corresponding to the position of the round rod 5041 is fixedly installed on the guide rail seat 2. The number of top rods 501 is matched with the number of round rods 5041, and the diameter of the top rod 501 is less than or equal to the diameter of the round rod 5041. This allows the top rod 501 to push the shaft 504 to retract into the sleeve 503 after the bracket 1 drives the base 4 to move away from the furnace body 3. This releases the transmission connection between the shaft 504 and the adjusting component 6. At this time, when the adjusting component 6 rotates again, the shaft 504 and the sleeve 503 no longer rotate.

[0031] In the above structure, such as Figure 4 As shown, the base 4 has a T-shaped design and is in the state after rotating 90 degrees clockwise. The sleeve 503 and the shaft 504 are located in the horizontal part of the base 4, while the two rollers 502 are located at both ends of the vertical part of the base 4.

[0032] Reference Figures 1 to 4 In this embodiment, preferably, the adjustment component 6 includes a motor 601 fixedly mounted on the bracket 1 and six driven wheels 602 rotatably mounted on the bracket 1. The number of driven wheels 602 is adapted to the number of shafts 504. The motor 601 is a servo motor 601 capable of forward and reverse rotation. Its output shaft is fixedly mounted with a drive wheel 603 that is connected to one of the driven wheels 602. A transmission belt 604 is sleeved together among the six driven wheels 602, thereby enabling the synchronous rotation of the six driven wheels 602, which in turn enables the synchronous rotation of all shafts 504. Finally, the rotation of the roller 502 drives the material 7 to rotate.

[0033] Among them, such as Figures 3 to 5 As shown, the shaft 504 and the driven wheel 602 are connected by a key shaft assembly transmission. When the top rod 501 abuts against the end of the shaft 504, causing the shaft 504 to retract into the sleeve 503, the shaft 504 and the driven wheel 602 disengage. At this time, the rotation of the driven wheel 602 no longer drives the shaft 504 to rotate, thereby releasing the rotation state of the roller 502 and the material 7.

[0034] Furthermore, such as Figure 3 , Figure 5 and Figure 7As shown, a push rod 607 is elastically connected to the surface of the transmission belt 604 near the bracket 1 via a second spring 605. The second spring 605 causes the push rod 607 to tend to extend out of the transmission belt 604. A protrusion 507 corresponding to the position of the shaft 504 is slidably mounted on the base 4. When the push rod 501 pushes the shaft 504 to retract into the sleeve 503, the shaft 504 drives the protrusion 507 to extend out of the base 4. At this time, as the push rod 607 moves with the transmission belt 604, it can contact the surface of the protrusion 507 and push the protrusion 507 and the base 4 to translate along the slide groove 101.

[0035] Specifically, such as Figure 4 and Figure 5 As shown, an arc edge that can be formed on the edge 5042 to movably fit with the protrusion 507 is provided. When the round rod 5041 extends out of the sleeve 503 under the action of the first spring 505 and is connected to the driven wheel 602, the protrusion 507 and the arc edge are movably fitted. At this time, the top of the protrusion 507 is coplanar with the top of the base 4. When the round rod 5041 retracts into the sleeve 503 under the action of the top rod 501, the movement of the round rod 5041 and the edge 5042 can drive the protrusion 507 to extend out of the base 4 through the arc edge.

[0036] Correspondingly, such as Figure 3 As shown, a cavity 102 corresponding to the top position of the base 4 is opened on the surface of the bracket 1 away from the furnace body 3. A chamfer can be set in the cavity 102 to facilitate the telescopic movement of the push rod 607 relative to the transmission belt 604. When the transmission belt 604 drives the push rod 607 into the cavity 102, the second spring 605 causes the push rod 607 to extend. At this time, the protrusion 507 extends from the top of the base 4 under the action of the shaft 504. Then, when the transmission belt 604 drives the push rod 607 to move, the push rod 607 can push the protrusion 507 and the base 4 to move.

[0037] Through the above design, the transmission belt 604 provides the feasibility for the synchronous rotation of all driven wheels 602, and enables the push rod 607 to have a horizontal travel, thereby providing the feasibility for the base 4 to move along the slide groove 101. Therefore, the overall functionality of the transmission belt 604 is stronger. Moreover, the arrangement of the transmission belt 604 corresponds to the arrangement of the base 4. After the base 4 is arranged in an array, the transmission belt 604 naturally enables the push rod 607 to have a horizontal travel. Subsequently, the push rod 607 acts on the protrusion 507 and the base 4, and the two complement each other.

[0038] It should be noted that in this embodiment, the transmission between the driving wheel 603 and the driven wheel 602, as well as the transmission of the six driven wheels 602 through the transmission belt 604, can be carried out by selecting existing sprockets and chain belts according to the requirements, and combined with existing gear meshing transmission. Furthermore, the thickness of the transmission belt 604 can also be increased or decreased according to the requirements.

[0039] To further increase the speed of pushing base 4, such as Figure 6 As shown, the number of push rods 607 on the transmission belt 604 can be set to several, and the several push rods 607 are arranged at equal intervals based on the transmission belt 604, so that one of the push rods 607 can quickly contact the protrusion 507, thereby quickly pushing the base 4 to move along the slide groove 101.

[0040] To further increase the speed of pushing base 4, such as Figure 8 As shown, protrusions 507 are slidably installed on the base 4 corresponding to the cavity 102. The edges 5042 on these bases 4 are also provided with arc edges, so that when the push rod 501 pushes the round rod 5041 to retract into the sleeve 503, all the protrusions 507 above can extend out from their respective bases 4 and contact one of the push rods 607, thereby ensuring the speed of the base 4 moving out.

[0041] In use, the support 1 moves along the guide rail seat 2 and drives the material 7 into the furnace body 3 through the roller shaft 502 to complete the roasting. During this process, the motor 601 starts and drives the two roller shafts 502 to rotate through the drive wheel 603, driven wheel 602, shaft 504, sleeve 503 and belt drive 506. The roller shafts 502 can drive the material 7 to rotate in the furnace body 3, thereby improving the roasting effect of the material 7. Next, the support 1 can move in the opposite direction along the guide rail seat 2 until the push rod 501 is inserted into the driven wheel 602 and pushes the shaft 504 to disengage from the driven wheel 602 (at this time, the edge 5042 is in the upper and lower corresponding state). At the same time, the edge 5042 pushes the protrusion 507 to extend out of the base 4. When the push rod 607 moves into the cavity 102 with the transmission belt 604, it can contact the extended protrusion 507 and push the base 4 to move along the slide groove 101. Multiple bases 4 move synchronously through the horizontal bar 401 and the vertical bar 402, so that all bases 4 can be moved out from one side of the support 1. During this process, the roller 502 can maintain the support state for the roasted material 7.

[0042] In summary, through the cooperation of the driven wheel 602, shaft 504, sleeve 503 and roller 502, the material 7 can be driven to rotate inside the furnace body 3, which helps to ensure that the material 7 is heated evenly, thereby ensuring the roasting effect of the material 7 and the overall quality reliability.

[0043] Through the cooperation of push rod 607, transmission belt 604, base 4 and protrusion 507, after roasting, all bases 4 can be pushed out from one side of support 1. When they are moved out, roller 502 can maintain the support state for the roasted material 7. This design allows the roasted material 7 to be exposed from one side of support 1. At this time, the loading and unloading of material 7 is not restricted by the structure of support 1. Workers can quickly pick up and put down material 7 individually from one side of support 1, or use external equipment to simultaneously pick up and put down all material 7 at once, thereby effectively improving the loading and unloading speed of material 7. At the same time, the above loading and unloading method can avoid collision damage between adjacent material 7 after roasting. After roasting, material 7 does not need to move along roller 502 or other structures, thereby further ensuring the overall roasting quality of material 7.

[0044] The overall structure is simple and more functional. The transmission belt 604 enables the synchronous rotation of all driven wheels 602, thereby enabling all materials 7 to rotate in the furnace body 3. On the other hand, it drives the push rod 607 to move, which in turn enables the base 4 to move out of the support 1. The linkage effect is better and the practicality is higher.

[0045] Example 2: Please see Figures 1 to 10 Based on Embodiment 1, to increase the movable distance of the base 4 from the bracket 1, improvements are made to the base 4 and the protrusion 507: A notch 403 is provided on the base 4 at the edge, and a side plate 508 fixedly connected to the protrusion 507 is provided within the notch 403. The top surface of the side plate 508 is flush with the top surface of the protrusion 507, and several grooves 509 are provided on the side plate 508. In this embodiment, as... Figure 1 and Figure 3 As shown, corresponding to the counterclockwise rotation of the driven wheel 602, the side plate 508 is located on the upper right base 4, and the side plate 508, like the base 4, is also hidden in the slide groove 101.

[0046] In the above structure, such as Figure 9 As shown, when push rod 607 enters cavity 102 and contacts protrusion 507, protrusion 507 corresponds to base 4 with notch 403. Subsequent push rods 607 entering cavity 102 can also correspond to side plate 508 and enter groove 509. Through this design, after push rod 607 pushes protrusion 507 on the outermost base 4, subsequent push rods 607, following the continued movement of transmission belt 604, can extend into groove 509 to push side plate 508. This, in turn, allows protrusion 507 and base 4 to move further along slide groove 101 via side plate 508, ultimately enabling all bases 4 to extend further from one side of bracket 1, facilitating faster loading and unloading of all materials 7.

[0047] Reference Figure 5 and Figure 10 A circular ring 5043, which is fixedly connected to the edge 5042, is fixedly mounted on the circular rod 5041. The surface of the circular ring 5043 near the sleeve 503 has a chamfer. By replacing the arc edge on the edge 5042 with the chamfered circular ring 5043, the circular ring 5043 is in movable contact with the bottom of the protrusion 507. With the above design, the stopping angle of the driven wheel 602 driving the circular rod 5041 is not restricted. At this time, no matter which direction the edge 5042 is facing, the movement of the circular rod 5041 driving the circular ring 5043 will cause the protrusion 507 to extend from the top of the base 4.

[0048] In use, the driven wheel 602, transmission belt 604, shaft 504, and roller 502 can drive the material 7 to rotate within the furnace body 3, improving the roasting effect. The roasted material 7 can be moved out from one side of the support 1 via the base 4 for easy loading and unloading. The working process and effect of this part are the same as in Example 1, and will not be repeated here. The difference is that when the round rod 5041 retracts into the sleeve 503, causing the protrusion 507 to extend from the top of the base 4, the protrusion 507 can drive the side plate 508 to move synchronously. At this time, when the transmission belt 604 drives the push rod 607 into the cavity 102, it can first contact the protrusion 507. When the upper right base 4 reaches the other side of the cavity 102, the subsequent push rod 607 can contact the groove 509 of the side plate 508, thereby pushing all the bases 4 to move a greater distance from one side of the support 1.

[0049] Compared to Embodiment 1, the combination of push rod 607, protrusion 507, side plate 508 and groove 509 can drive all bases 4 to move a greater distance from one side of the support 1, so that the roasted material 7 is further away from the support 1, which can further facilitate the rapid loading and unloading of the roasted material 7, further reduce the influence of the support 1 on the loading and unloading of the material 7, and relatively increase the loading and unloading speed of the material 7.

[0050] The overall design is combined with the arrangement of multiple push rods 607. The side plate 508 not only contacts the multiple push rods 607 to allow the base 4 to move further from the support 1, but also ensures that the base 4 will not fall off the support 1 after moving further, because the side plate 508 itself is also located in the slide groove 101, which can ensure the stable operation of the overall structure.

[0051] Example 3: Please see Figures 1 to 10 This invention provides a graphite electrode calcination method, which uses any one of the calcination devices in Embodiment 1 or 2, and therefore also has corresponding beneficial effects.

[0052] Specifically, material 7 is first placed onto support component 5 in sequence. Then, bracket 1 moves along guide rail 2, causing support component 5 and material 7 to enter furnace body 3 for roasting. During this process, adjustment component 6 is activated, which drives material 7 to rotate within furnace body 3 via support component 5, thus improving the roasting effect of material 7. Next, bracket 1 returns to its original position along guide rail 2, and adjustment component 6 is activated, which drives all bases 4 to move out from one side of bracket 1 via support component 5.

[0053] During the above process, when the material 7 is placed on the support component 5, the base 4 is also in a state of being moved out from one side of the bracket 1, which facilitates the rapid loading and unloading of all materials 7.
