Description

Technical Field

[0001] This utility model relates to the field of graphitization furnace technology, and in particular to a snap-fit ​​mechanism and a vertical two-stage graphitization furnace device. Background Technology

[0002] The vertical two-stage graphitization furnace is an industrial equipment used to produce graphite materials. In the existing technology, the vertical two-stage graphitization furnace generally adopts an integrated device. This device is mostly horizontal and open in structure. This structural design results in a large footprint, which not only puts high demands on the spatial layout of the factory, but also easily causes a large amount of heat loss in actual operation. Due to the large heat loss, the energy consumption of the equipment is relatively high, which increases production costs to a certain extent and also places a greater burden on the environment.

[0003] To address the aforementioned issues, existing technologies have introduced vertically split-type two-stage graphitization furnaces. However, the connection methods for these split-type devices mostly rely on bolt fixing. This connection method is not convenient during installation and disassembly, especially when frequent equipment maintenance and component replacement are required. It is time-consuming and labor-intensive, which is not conducive to improving production efficiency and reducing operation and maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the inconvenience of disassembly and assembly of the existing split-type two-stage graphitization furnace, and to provide a snap-fit ​​mechanism and a vertical two-stage graphitization furnace device.

[0005] The present invention solves the above-mentioned technical problems through the following technical solution:

[0006] A snap-fit ​​mechanism, comprising:

[0007] A snap-fit ​​rod, the snap-fit ​​rod having a snap-fit ​​portion and a first outer flange disposed on the outer periphery of the snap-fit ​​portion;

[0008] A snap-fit ​​sleeve having a base and a second outer flange disposed on the outer periphery of the base;

[0009] The base has an open receiving cavity. The snap-fit ​​part extends into the receiving cavity from the end opposite to the first outer flange along the axial direction of the snap-fit ​​rod and is clearance-fitted with the receiving cavity. The first outer flange and the second outer flange form a snap-fit ​​gap between them along the axial direction of the snap-fit ​​rod.

[0010] The side wall of the receiving cavity is provided with a through clearance hole, and the extension direction of the clearance hole is not parallel to the axial direction of the snap-fit ​​rod;

[0011] A locking block is slidably disposed in the clearance hole. When the locking block is in the locked position along the sliding direction, it abuts against the surface of the latching rod to fix the latching rod on the latching sleeve. When the locking block is in the unlocked position along the sliding direction, it disengages from the latching rod.

[0012] A drive component for driving the locking block to move between the locked position and the unlocked position.

[0013] In this technical solution, after the locking block is driven to the unlocked position, the locking part of the locking rod is inserted into the receiving cavity of the locking sleeve. Then, the locking block is driven to the locked position, thereby fixing the locking rod inside the locking sleeve and fixing the locking gap. When using the locking structure to fix other structures, the structure to be fixed needs to be provided with a connecting through hole. After the locking part passes through the connecting through hole, it is inserted into the receiving cavity of the locking sleeve, so that the structure to be fixed is clamped in the locking gap. The locking and fixing of the structure is completed by the first outer flange and the second outer flange abutting against the structure to be fixed.

[0014] Preferably, the outer periphery of the latching part has a latching groove, and when the locking block is in the locking position, the end of the locking block near the latching rod along the sliding direction extends into the latching groove.

[0015] This technical solution provides a specific structural form for fixing the locking block to the latching rod: the locking block extends into the latching groove on the latching rod when it is in the locked position to fix the latching rod, which can better prevent the latching rod from falling out of the receiving cavity and make the locking of the locking block more reliable.

[0016] Preferably, the driving assembly has a driving block that is slidably disposed on the outside of the snap-fit ​​sleeve along the axial direction of the snap-fit ​​rod. The outer surface of the driving block is inclined inward along the axial direction of the snap-fit ​​rod from the snap-fit ​​sleeve toward the snap-fit ​​rod. The locking block has a third outer flange at one end away from the snap-fit ​​rod along the sliding direction. The third outer flange extends out of the relief hole and abuts the driving block between the first outer flange and the side wall of the receiving cavity.

[0017] In this technical solution, a specific structural form for driving the locking block to unlock is provided: the distance between the driving block and the axis of the locking rod varies along the axial direction of the locking rod. The locking block is pushed to move away from the locking rod by the different contact positions between the first outer flange and the outer surface of the driving block when the driving block moves along the axial direction of the locking rod, that is, the locking block is pushed to move from the locking position to the unlocking position.

[0018] The drive assembly further includes a main gear, a driven gear, a screw, and a slider. The main gear meshes with the driven gear, the shaft of the driven gear is connected to the shaft of the screw, the screw and the slider are threadedly connected and drive the slider to move axially along the locking rod, and the slider and the drive block are fixedly connected.

[0019] In this technical solution, a specific structural form is provided for a driving component that moves the driving block along the axial direction of the locking rod: the driving block is driven to move along the axial direction of the locking rod through the cooperation of gears, screws and sliders, and the structure is simple and reliable.

[0020] Preferably, the drive assembly further includes a knob, which is fixedly connected to the main gear, and the outer peripheral side of the knob has an anti-slip structure.

[0021] In this technical solution, a knob is used to rotate the gear. The structure is simple and easy to operate. The anti-slip structure on the outer periphery of the knob makes it easy to rotate.

[0022] Preferably, the drive assembly further includes a first elastic element disposed along the sliding direction of the locking block, one end of the first elastic element along the extension direction being connected to the snap-fit ​​sleeve, and the other end being connected to the locking block.

[0023] In this technical solution, by setting a first elastic element, when the driving block moves away from the locking rod along the axial direction of the locking rod, the rebound of the first elastic element can make the locking block move towards the locking rod, that is, make the locking block move from the unlocking position to the locking position. The structure is simple and reliable.

[0024] Preferably, there are multiple clearance holes, which are spaced apart circumferentially along the locking mechanism, and there are multiple locking blocks, which are arranged in a one-to-one correspondence with the clearance holes.

[0025] In this technical solution, the reliability of the locking mechanism is improved by setting multiple clearance holes and locking blocks.

[0026] Preferably, the snap-fit ​​mechanism further includes a protrusion formed on the inner periphery of the snap-fit ​​sleeve and a groove formed on the outer periphery of the snap-fit ​​rod, the protrusion and the groove engaging, and both the protrusion and the groove extending axially along the snap-fit ​​rod.

[0027] In this technical solution, by setting protrusions and grooves, the circumferential positioning of the locking rod and locking sleeve is achieved, preventing the locking rod and locking sleeve from rotating relative to each other along the circumference of the locking rod, thereby improving the structural stability of the locking mechanism.

[0028] Preferably, the snap-fit ​​mechanism further includes a second elastic element, which is compressed between the inner wall of the receiving cavity along the axial direction of the snap-fit ​​rod toward the inner wall of the snap-fit ​​rod and the end face of the snap-fit ​​rod along the axial direction of the snap-fit ​​rod toward the end face of the snap-fit ​​sleeve.

[0029] In this technical solution, the convenience of disassembling the snap-fit ​​mechanism is improved. After the snap-fit ​​block is disengaged from the snap-fit ​​rod, the elastic element applies a force to the snap-fit ​​rod, causing the snap-fit ​​rod to disengage from the snap-fit ​​sleeve.

[0030] Preferably, the locking mechanism further includes a spring plate, which is disposed axially between the second elastic member and the locking rod along the locking rod.

[0031] In this technical solution, the rebound plate makes the force distribution of the second elastic element more uniform, thereby improving the reliability of the snap-fit ​​mechanism.

[0032] A vertical two-stage graphitization furnace device includes a calcination furnace body, a graphitization furnace body, and a snap-fit ​​mechanism as described above. The vertical two-stage graphitization furnace device further includes:

[0033] Two connecting rings, one of which is connected to one end of the calcination furnace body along the height direction near the graphitization furnace body, and the other connecting ring is connected to one end of the graphitization furnace body along the height direction near the calcination furnace body. The two connecting rings are provided with multiple connecting through holes arranged at intervals along their circumference and penetrating the connecting rings along the height direction. The connecting through holes on the two connecting rings correspond one-to-one, and the two corresponding connecting through holes are coaxial.

[0034] In a plurality of the aforementioned snap-fit ​​mechanisms, the snap-fit ​​assembly formed by the snap-fit ​​rod and the snap-fit ​​sleeve in a single snap-fit ​​mechanism passes through two corresponding connecting through holes, such that two connecting rings are located within the snap-fit ​​gap, with one connecting ring abutting against the first outer flange and the other connecting ring abutting against the second outer flange.

[0035] By using a snap-fit ​​mechanism to connect the calcination furnace body and the graphitization furnace body, connecting rings are set on the outer periphery of the calcination furnace body and the outer periphery of the graphitization furnace body. The snap-fit ​​component of the snap-fit ​​mechanism passes through the connecting through holes on the two connecting rings, so that the two connecting rings are fixed in the snap-fit ​​gap, making it easy to assemble and disassemble the calcination furnace body and the graphitization furnace body, and ensuring high connection reliability.

[0036] Preferably, the vertical two-stage graphitization furnace equipment further includes a cooling furnace body, the furnace cavity of the cooling furnace body is connected to the furnace cavity of the graphitization furnace body, and the cooling furnace body has an air inlet and an air outlet extending from the outer surface of the cooling furnace body into the furnace cavity of the cooling furnace body.

[0037] In this technical solution, a cooling furnace body with an air inlet and an air outlet is set up to achieve cold air circulation and quickly reduce the temperature of the material passing through the cooling furnace body.

[0038] Preferably, the air inlet and the air outlet are arranged horizontally at opposite ends of the cooling furnace body.

[0039] In this technical solution, by setting the air inlet and outlet horizontally at opposite ends of the cooling furnace body, the coverage area of ​​the cold air circulation zone is increased, thereby improving the cooling effect on the materials.

[0040] Preferably, the cooling furnace body also has a plurality of discharge ports extending from the outer surface of the cooling furnace body into the furnace cavity of the cooling furnace body, and the discharge ports are located below the air inlet and the air outlet.

[0041] In this technical solution, by setting the discharge port below the air inlet and outlet, the material is cooled by air before being collected, resulting in a higher cooling effect.

[0042] The significant advantages of this invention are as follows: After the locking block is moved to the unlocked position, the locking part of the locking rod extends into the receiving cavity of the locking sleeve. Then, the locking block is moved to the locked position, thereby fixing the locking rod inside the locking sleeve and thus fixing the locking gap. When using the locking structure to fix other structures, the structure to be fixed needs to have a connecting through hole. The locking part is passed through the connecting through hole and inserted into the receiving cavity of the locking sleeve, so that the structure to be fixed is clamped in the locking gap. The locking and fixing of the structure is completed by the first and second outer flanges abutting against the structure to be fixed. Attached Figure Description

[0087] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment.

[0088] like Figures 1-7As shown, this embodiment provides a snap-fit ​​mechanism and a vertical two-stage graphitization furnace device 100. The snap-fit ​​mechanism 5 includes a snap-fit ​​rod 53, a snap-fit ​​sleeve 51, a locking block 54, and a drive assembly 52. ​​The snap-fit ​​rod 53 has a snap-fit ​​portion 535 and a first outer flange 532 disposed on the outer periphery of the snap-fit ​​portion 535. The snap-fit ​​sleeve 51 has a base and a second outer flange 515 disposed on the outer periphery of the base. An open receiving cavity 5101 is provided in the base. The end of the snap-fit ​​portion 535, which is axially opposite to the first outer flange 532 along the snap-fit ​​rod 53, extends into the receiving cavity 5101 and is clearance-fitted with the receiving cavity 5101. A snap-fit ​​gap 501 is formed between the flange 532 and the second outer flange 515 along the axial direction of the snap-fit ​​rod 53; the side wall of the receiving cavity 5101 is provided with a through clearance hole 5102, the extension direction of the clearance hole 5102 is not parallel to the axial direction of the snap-fit ​​rod 53, the locking block 54 is slidably disposed in the clearance hole 5102, when the locking block 54 is in the locked position along the sliding direction, it abuts against the surface of the snap-fit ​​rod 53 and fixes the snap-fit ​​rod 53 on the snap-fit ​​sleeve 51, and when it is in the unlocked position along the sliding direction, it disengages from the snap-fit ​​rod 53; the driving assembly 52 is used to drive the locking block 54 to move between the locked position and the unlocked position. After the locking block 54 is moved to the unlocked position, the locking part 535 of the locking rod 53 is inserted into the receiving cavity 5101 of the locking sleeve 51. Then, the locking block 54 is moved to the locked position, thereby fixing the locking rod 53 in the locking sleeve 51 and fixing the locking gap 501. When using the locking structure to fix other structures, the structure to be fixed needs to be provided with a connecting through hole. After the locking part 535 passes through the connecting through hole, it is inserted into the receiving cavity 5101 of the locking sleeve 51, so that the structure to be fixed is clamped in the locking gap 501. The locking and fixing of the structure can be completed by the first outer flange 532 and the second outer flange 515 abutting against the structure to be fixed.

[0089] In this embodiment, as Figure 1As shown, the vertical two-stage graphitization furnace equipment 100 includes a calcination furnace body 1 and a graphitization furnace body 2, and also includes two connecting rings 4 and multiple snap-fit ​​mechanisms 5 as described above. One connecting ring 4 is connected to the end of the calcination furnace body 1 near the graphitization furnace body 2 along the height direction, and the other connecting ring 4 is connected to the end of the graphitization furnace body 2 near the calcination furnace body 1 along the height direction. The two connecting rings 4 are provided with multiple connecting through holes arranged at intervals along their circumference and penetrating the connecting rings 4 along the height direction. The holes correspond one-to-one, and the two corresponding connecting through holes are coaxial; a single snap-fit ​​mechanism 5 is set at the two corresponding connecting through holes, the snap-fit ​​part of the snap-fit ​​rod extends into the two corresponding connecting through holes of the two connecting rings, and the snap-fit ​​sleeve is located outside the two connecting rings; the snap-fit ​​assembly formed by the snap-fit ​​rod 53 and the snap-fit ​​sleeve 51 in the single snap-fit ​​mechanism 5 passes through the two corresponding connecting through holes, so that the two connecting rings 4 are located in the snap-fit ​​gap, one of the connecting rings 4 abuts against the first outer flange 532, and the other connecting ring abuts against the second outer flange 515.

[0090] Specifically, in this embodiment, since the second outer flange 515 is located at the end of the base near the opening of the receiving cavity, the snap-fit ​​sleeve 53 cannot extend into the connecting through hole. Instead, the snap-fit ​​part passes through the corresponding two connecting through holes and extends into the receiving cavity to cooperate with the snap-fit ​​sleeve 53, so that the two connecting rings 4 are located in the snap-fit ​​gap 501. One connecting ring 4 abuts against the first outer flange 532, and the other connecting ring 4 abuts against the second outer flange 515. By using the snap-fit ​​mechanism 5 to connect the calcining furnace body 1 and the graphitization furnace body 2, connecting rings 4 are provided on the outer peripheral side of the calcining furnace body 1 and the outer peripheral side of the graphitization furnace body 2. The snap-fit ​​part of the snap-fit ​​mechanism 5 passes through the connecting through holes on the two connecting rings 4, so that the two connecting rings 4 are fixed in the snap-fit ​​gap 501, making it easy to assemble and disassemble the calcining furnace body 1 and the graphitization furnace body 2, and ensuring high connection reliability.

[0091] Specifically, compared to bolted connections, the vertical dual-stage graphitization furnace equipment 100 in this embodiment uses the snap-fit ​​mechanism 5 to connect the calcination furnace body 1 and the graphitization furnace body 2, which has the following advantages: First, the snap-fit ​​mechanism 5, through its unique mechanical design, can achieve a quick and stable connection between the calcination furnace body 1 and the graphitization furnace body 2. This design not only simplifies the connection process but also improves the stability and reliability of the connection. Traditional bolted connections require tightening or loosening bolts one by one, which is a cumbersome and time-consuming process. The snap-fit ​​mechanism 5, on the other hand, allows for quick connection or disassembly by adjusting the position of the locking block 54 through simple mechanical operations, such as rotating the knob 528. Second, the design of the snap-fit ​​mechanism 5 ensures the consistency and repeatability of each connection. By rotating the knob 528 and the main gear 522, the position of the locking block 54 can be precisely controlled, thereby ensuring accurate docking between the calcination furnace body 1 and the graphitization furnace body 2. In contrast, bolted connections cannot achieve such precise position control, which may lead to inconsistent connection quality. Furthermore, the snap-fit ​​mechanism 5 reduces the need for manual operation, eliminating the need for external tools such as wrenches for installation and disassembly. This design not only improves operational convenience but also reduces the labor intensity of operators. In contrast, bolted connections require the use of wrenches and other tools to tighten or loosen bolts one by one, making the operation process more cumbersome. Finally, the snap-fit ​​mechanism 5 has a compact design that does not occupy too much space, contributing to the miniaturization and weight reduction of the equipment. Bolted connections, on the other hand, require sufficient space to accommodate bolts and nuts, which may increase the size of the equipment.

[0092] In other embodiments, the base of the snap-fit ​​sleeve may pass through the two corresponding connecting through holes in the two connecting rings and then engage with the snap-fit ​​rod; alternatively, the snap-fit ​​portion and the base may extend into the connecting through holes and engage within them. In this case, the first outer flange is not located at the end of the base near the receiving cavity, but rather at a distance from that end. The specific part of the snap-fit ​​assembly extending into the connecting through hole depends on the specific structure of the snap-fit ​​assembly and will not be elaborated further here.

[0093] When using the snap-fit ​​mechanism 5 to connect the calcining furnace body 1 and the graphitization furnace body 2, the first outer flange 532 can abut against the connecting ring 4 on the calcining furnace body 1, and the second outer flange 515 can abut against the connecting ring 4 on the graphitization furnace body 2; or the second outer flange 515 can abut against the connecting ring 4 on the calcining furnace body 1, and the first outer flange 532 can abut against the connecting ring 4 on the graphitization furnace body 2. Which connecting piece the first and second outer flanges abut against depends on the vertical position of the snap-fit ​​rod 53 and the snap-fit ​​sleeve 51. Specifically, in this embodiment, the second outer flange 515 abuts against the connecting ring 4 on the calcining furnace body 1, and the first outer flange 532 abuts against the connecting ring 4 on the graphitization furnace body 2.

[0094] Specifically in this embodiment, such as Figures 2-4As shown, the outer periphery of the latching part has a latching groove 531. When the locking block 54 is in the locked position, the end of the locking block 54 near the latching rod 53 extends into the latching groove 531 along the sliding direction. That is, in this embodiment, the latching rod 53 is fixed by the locking block 54 engaging with the latching groove 531 on the latching rod 53 when in the locked position. When the locking block 54 engages with the latching groove 531, the locking block 54 presses against the latching rod 53, fixing the latching rod 53 in the latching sleeve 51. The latching rod 53 and the latching sleeve 51 cannot move relative to each other along the axial direction of the latching rod, thus forming a limit along the axial direction of the latching rod.

[0095] In this embodiment, the driving assembly 52 has a driving block 521, which is slidably disposed on the outside of the snap-fit ​​sleeve 51 along the axial direction of the snap-fit ​​rod. The outer surface of the driving block 521 is inclined inward along the axial direction of the snap-fit ​​rod from the snap-fit ​​sleeve 51 toward the snap-fit ​​rod 53. The locking block 54 has a third outer flange 541 at one end away from the snap-fit ​​rod 53 along the sliding direction. The surface of the third outer flange 541 facing the snap-fit ​​rod 53 abuts against the outer surface of the driving block 521. That is, the outer surface of the driving block 521 forms a slope, and the thickness of the driving block 521 gradually decreases along the direction close to the snap-fit ​​rod 53, and the distance between the outer surface and the axis of the snap-fit ​​rod 53 gradually decreases. The locking block 54 is pushed to move away from the snap-fit ​​rod 53 by the different abutment positions of the third outer flange 541 and the outer surface of the driving block 521 when the driving block 521 moves along the axial direction of the snap-fit ​​rod, that is, the locking block 54 is pushed to move from the locked position to the unlocked position.

[0096] like Figure 4 and Figure 6 As shown, the drive block 521 is provided with a groove that extends through the sliding direction of the locking block 54. The locking block 54 passes through the groove, and the third outer flange 541 of the locking block 54 abuts against the outer surface of the drive block 521. When the drive block 521 moves closer to the locking rod 53 along the axial direction of the locking rod, the thickness of the drive block 521 at the point of contact with the third outer flange 541 gradually increases, and the distance from the axis of the locking rod 53 gradually increases, thereby pushing the locking block 54 to move away from the locking rod 53 along the sliding direction, so as to unlock or not block the locking rod 53 from entering the receiving cavity 5101.

[0097] In this embodiment, the drive assembly 52 further includes a main gear 522, a driven gear 523, a screw 525, and a slider 524. The main gear 522 meshes with the driven gear 523, the shaft of the driven gear 523 is connected to the shaft of the screw 525, the screw 525 and the slider 524 are threadedly connected, and the screw 525 drives the slider 524 to move axially along the locking rod. The slider 524 and the drive block 521 are fixedly connected. Through the cooperation of the gear, screw 525, and slider 524, the drive block 521 is driven to move axially along the locking rod, resulting in a simple and reliable structure.

[0098] Specifically, in this embodiment, the rotational motion of the screws 525 is converted into the linear motion of the slider 524 by simultaneously turning multiple screws 525. The slider 524 has a threaded cylinder 5241 fixedly connected to it, and the screws 525 are threadedly engaged with the threaded cylinder 5241. In other embodiments, other methods in the prior art can also be used to convert the rotational motion of the screws 525 into the linear motion of the slider 524, which will not be elaborated here.

[0099] Meanwhile, the drive assembly 52 also includes a knob 528, which is fixedly connected to the main gear 522. The outer periphery of the knob 528 has an anti-slip structure, the specific form of which is existing technology, such as providing raised strips or knurling on the outer periphery of the knob 528. That is to say, in this embodiment, the rotation of the gear is achieved by turning the knob 528, which makes the structure simple and the operation convenient. The anti-slip structure on the outer periphery of the knob 528 facilitates turning.

[0100] Furthermore, in this embodiment, the drive assembly 52 also includes a first elastic element 526 disposed along the sliding direction of the locking block 54. One end of the first elastic element 526 along the extension direction is connected to the snap-fit ​​sleeve 51, and the other end is connected to the locking block 54. By providing the first elastic element 526, when the drive block 521 moves away from the snap-fit ​​rod 53 along the axial direction of the snap-fit ​​rod, the rebound of the first elastic element 526 can cause the locking block 54 to move towards the snap-fit ​​rod 53, that is, to move the locking block 54 from the unlocked position to the locked position.

[0101] Specifically in this embodiment, such as Figure 6 and Figure 7 As shown, the first elastic element 526 is a helical spring. The end of the first elastic element 526 near the locking rod 53 is fixedly connected to the locking sleeve 51, and the end away from the locking rod 53 is fixedly connected to the locking block 54. When the locking block 54 is in the locked position, the first elastic element 526 is in its original length state. When the locking block 54 is pulled outward, the first elastic element 526 is stretched, thereby having a restoring force to contract inward.

[0102] Of course, in other embodiments, the first elastic element 526 may also be fixedly connected to the locking block 54 at one end near the locking rod 53, and fixedly connected to the locking sleeve 51 at the other end away from the locking rod 53. When the locking block 54 is in the locked position, the first elastic element 526 is in its original length state. When the locking block 54 is pulled outward, the first elastic element 526 is compressed, thereby having a restoring force to extend inward. This will not be described in detail here.

[0103] In this embodiment, the snap-fit ​​sleeve 51 has a second outer flange 515 at one end of the snap-fit ​​rod 53 along the axial direction of the snap-fit ​​rod, and the snap-fit ​​rod 53 has a first outer flange 532 at one end of the snap-fit ​​rod 53 away from the snap-fit ​​sleeve 51 along the axial direction of the snap-fit ​​rod. The surfaces of the second outer flange 515 facing the connecting ring 4 and the surfaces of the first outer flange 532 facing the connecting ring 4 both abut against the connecting ring 4. That is, by providing the first outer flange 532 and the second outer flange 515 on the snap-fit ​​rod 53 and the snap-fit ​​sleeve 51 respectively, and by having the second outer flange 515 and the first outer flange 532 abut against the connecting ring 4, the snap-fit ​​mechanism will not fall off the connecting ring from either end along the axial direction of the snap-fit ​​rod when it is in the locked position, thereby achieving the fixation of the connecting ring 4 when the snap-fit ​​mechanism is locked.

[0104] In this embodiment, there are multiple clearance holes 5102 and locking blocks 54. The multiple clearance holes 5102 are arranged at intervals along the circumference of the locking mechanism, and the locking blocks 54 are arranged in a one-to-one correspondence with the clearance holes 5102. By providing multiple clearance holes 5102 and locking blocks 54, the reliability of the locking mechanism is improved.

[0105] In this embodiment, the latching mechanism 5 further includes a protrusion 513 formed on the inner circumferential side of the latching sleeve 51 and a groove 534 formed on the outer circumferential side of the latching rod 53. The protrusion 513 and the groove 534 cooperate, and both the protrusion 513 and the groove 534 extend axially along the latching rod. By providing the protrusion 513 and the groove 534, the circumferential positioning of the latching rod and the latching sleeve is achieved, preventing the latching rod and the latching sleeve from rotating relative to each other circumferentially along the latching rod, thereby improving the structural stability of the latching mechanism.

[0106] In this embodiment, the snap-fit ​​mechanism 5 further includes a second elastic element 6, which is also a helical spring. The second elastic element 6 is compressed between the inner wall of the receiving cavity 5101 along the axial direction of the snap-fit ​​rod towards the snap-fit ​​rod 53 and the end face of the snap-fit ​​rod 53 along the axial direction of the snap-fit ​​rod towards the snap-fit ​​sleeve 51. By providing the second elastic element 6, the convenience of disassembling the snap-fit ​​mechanism 5 is improved. When the snap-fit ​​block is pulled outward, the elastic element applies a force to the snap-fit ​​rod 53, causing the snap-fit ​​rod 53 to disengage from the snap-fit ​​sleeve 51.

[0107] Meanwhile, the snap-fit ​​mechanism 5 also includes a spring plate 7, which is arranged along the axial direction of the snap-fit ​​rod between the second elastic member 6 and the snap-fit ​​rod 53. The two ends of the second elastic member 6 are respectively connected to the snap-fit ​​sleeve 51 and the spring plate 7, so that the force distribution of the second elastic member 6 is more uniform and the reliability of the snap-fit ​​mechanism is improved.

[0108] When connecting the calcining furnace body 1 and the graphitization furnace body 2 using the snap-fit ​​mechanism 5, first align the connecting through holes on the two connecting rings 4 to ensure that the snap-fit ​​structure is in the unlocked position. If the snap-fit ​​structure is in the locked position, turn the knob 528 to unlock it. Insert the snap-fit ​​part 535 into the connecting through hole and extend the connecting ring from the other side, so that the first outer flange 532 abuts against one of the connecting rings 4. Put the snap-fit ​​sleeve 51 onto the snap-fit ​​part 535, insert the snap-fit ​​part 535 into the receiving cavity 5101 of the snap-fit ​​sleeve 51, and the second outer flange 515 abuts against the other connecting ring 4. Turn the knob 528 to move the locking block 54 to the locked position to complete the connection between the calcining furnace body 1 and the graphitization furnace body 2.

[0109] In this embodiment, as Figure 5 As shown, the vertical two-stage graphitization furnace equipment also includes a cooling furnace body 3. The furnace cavity of the cooling furnace body 3 is connected to the furnace cavity of the graphitization furnace body 2. The cooling furnace body 3 has an air inlet 31 and an air outlet 32 ​​that extend from the outer surface of the cooling furnace body 3 into the furnace cavity. By setting the cooling furnace body 3 with the air inlet 31 and the air outlet 32, cold air circulation is achieved, which quickly reduces the temperature of the material passing through the cooling furnace body 3.

[0110] Specifically, the air inlet 31 and air outlet 32 ​​are horizontally positioned at opposite ends of the cooling furnace body 3. "Opposite ends" here means that the air inlet 31 and air outlet 32 ​​are positioned as far apart as possible; for example, the air inlet 31 and air outlet 32 ​​could be positioned at the front and rear, or left and right sides of the cooling furnace body 3, respectively. This will not be elaborated further. By increasing the horizontal positioning of the air inlet 31 and air outlet 32 ​​at opposite ends of the cooling furnace body 3, the coverage area of ​​the cold air circulation zone is increased, improving the cooling effect on the materials.

[0111] Meanwhile, the cooling furnace body 3 also has several discharge ports 33 extending from the outer surface of the cooling furnace body 3 into the furnace cavity of the cooling furnace body 3. The discharge ports 33 are located below the air inlet 31 and the air outlet 32. By placing the discharge ports 33 below the air inlet 31 and the air outlet 32, the material is cooled by air before being collected, resulting in a higher cooling effect.

[0112] Specifically, in this embodiment, there are two feed inlets, so that materials can be collected from different discharge outlets 33.

[0113] In this embodiment, the calcination furnace body 1, the graphitization furnace body 2, and the cooling furnace body 3 are all supported by a support frame 8. The support frame 8 has four support legs and is hollowed out on the periphery. Along the axial direction of the snap-fit ​​rod 4, the calcination furnace body 1 and the graphitization furnace body 2 are arranged above the support frame 8, and the cooling furnace body 3 is arranged in the space surrounded by the four support legs.

[0114] In addition, the calcination furnace body 1 of the two-stage graphitization furnace body 2 in this embodiment is equipped with graphite positive electrodes and graphite negative electrodes (not shown in the figure). The graphite positive electrodes and graphite negative electrodes enter the furnace cavity of the calcination furnace body 1 through different side walls. A rotating electrode conveying device is also provided between the cooling furnace body 3 and the graphitization furnace body 2. The rotating electrode conveying device can replenish the consumed electrodes. That is, the rotating electrode conveying device is used to replenish the graphite positive electrodes and graphite negative electrodes after they are consumed. Automatic replenishment ensures the continuity and stability of production.

[0115] Meanwhile, the calcining furnace body 1 is also equipped with a feed pipe 11 and a sealing cover 12, through which the material enters the calcining furnace body 1.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
