Specific embodiments

[0034] The following will further elaborate on this application in conjunction with the attached Figures 1-7 drawings.

[0035] The embodiment of this application discloses an internal series graphitization furnace. Referring to Figures 1-3 , an internal series graphitization furnace includes a furnace body 1, a crucible 2 located inside the furnace body 1, a zoning mechanism 3 connected to the crucible 2, a driving mechanism 4 connected to the zoning mechanism 3, a blocking member 5 connected to the driving mechanism 4, and a coolant interface 8 connected to the driving mechanism 4. The zoning mechanism 3 includes a plurality of spacer plates 31, a rotating shaft 32 connected to the spacer plates 31, a dividing plate 34 detachably connected to the rotating shaft 32, and a sliding block 33 slidably connected to the spacer plates 31. The circumferential surface of the spacer plate 31 is attached to and slidably connected to the inner wall of the crucible 2. By providing a plurality of spacer plates 31, the interior of the crucible 2 is divided into a plurality of spaces, and users can place various materials in different spaces to achieve the purpose of processing different and multiple materials, saving resources.

[0036] Meanwhile, referring to Figures 3-4, the driving mechanism 4 includes a driving motor 41 fixedly connected to the furnace body 1 and a driving screw 42 rotatably connected to the crucible 2. The driving motor 41 is located outside the crucible 2, and the output end of the driving motor 41 can be coaxially and fixedly connected to the end of the driving screw 42 by means of a coupling. In the embodiment of the present application, the driving screw 42 is a graphite driving screw 42. A moving block 312 is provided at the center of the top of the spacer 31. The driving screw 42 passes through and is threadedly connected to a plurality of moving blocks 312. The moving block 312 is slidably connected to the top of the crucible 2, making the movement of the spacer 31 more stable while realizing the adjustment of the position of the spacer 31. When the user installs the spacer 31, the material is placed in front of the spacer 31, and then the adjacent spacers 31 are installed inside the crucible 2, and the positions of the adjacent spacers 31 are adjusted to complete the division of the internal space of the crucible 2, while reducing the interaction between adjacent spaces, reducing the possibility of material mutual contamination, improving the processing accuracy. At the same time, at least one ventilation hole can be opened at the top of the crucible 2 between adjacent spacers 31 to realize air exchange, improve the safety of the present application, achieve the purpose of the user to process multiple materials at the same time, improve the processing efficiency while saving resources.

[0037] Refer to Figure 3 , Figure 6 and Figure 7 , a blocking member 5 and a coolant interface 8 are provided at one end of the driving screw 42 away from the driving motor 41. The blocking member 5 is located outside the crucible 2, and the blocking member 5 is threadedly connected to the end of the driving screw 42 away from the driving motor 41. After the user installs the spacer 31, the driving motor 41 is turned off, and at the same time, the blocking member 5 is threadedly connected to the end of the driving screw 42, reducing the possibility of the spacer 31 sliding out of the crucible 2, improving the working stability and safety. At the same time, a cooling groove 421 is opened in the driving screw 42 along its own axis direction, and cooling holes 7 are provided at both ends of the driving screw 42. The blocking member 5 is provided with cooling holes 7. The cooling holes 7 on the driving screw 42 and the cooling holes 7 on the blocking member 5 are communicated with each other. The cooling holes 7 and the cooling groove 421 are communicated with each other. Internal threads are provided on the inner wall of the cooling hole 7, and the coolant interface 8 is threadedly connected to the inside of the cooling hole 7. After the user installs the spacer 31, the coolant interface 8 can be threadedly connected to the position of the cooling hole 7, and the external coolant is communicated with the coolant interface 8. The external coolant is communicated with the inside of the cooling hole 7 and the cooling groove 421 to cool the driving screw 42 and reduce the temperature of the driving screw 42, reducing the damage to the driving screw 42 caused by high temperature.

[0038] Refer to Figures 3-5, the spacer 31 is slidably connected to the crucible 2 along the axial direction of the crucible 2 to achieve stable connection of the spacer 31. The surface of the spacer 31 is provided with spacer grooves 311. Each spacer 31 is connected with two sliding blocks 33. One sliding block 33 is slidably connected to the top of the spacer groove 311, and the other sliding block 33 is slidably connected to the bottom of the spacer groove 311, so that the sliding block 33 can move stably. The axis of the rotating shaft 32 is parallel to the vertical direction. One end of the rotating shaft 32 passes through and is rotatably connected to the sliding block 33 at the top, and the other end of the rotating shaft 32 is rotatably connected to the sliding block 33 at the bottom. The two sliding blocks 33 support and position the rotating shaft 32, making the movement of the rotating shaft 32 more stable. One end of the dividing plate 34 is fixedly connected to the rotating shaft 32. When the rotating shaft 32 rotates, the other end of the dividing plate 34 moves along the direction close to or away from the bottom of the spacer groove 311. The end of the dividing plate 34 away from the rotating shaft 32 abuts against the adjacent spacer 31. The driving mechanism 4 is drivingly connected to the spacer 31, and the spacer 31 moves along the axial direction of the crucible 2.

[0039] Refer to Figures 3-5 , one end of the dividing plate 34 is provided with a connecting end 341. The cross section of the connecting end 341 is an arc surface. The connecting end 341 winds around and semi - surrounds the rotating shaft 32. The rotating shaft 32 is provided with a plurality of connecting holes 6 in the direction perpendicular to the axis, which increases the contact area between the connecting end 341 and the rotating shaft 32 and improves the connection stability. The plurality of connecting holes 6 are uniformly arranged along the axial direction of the rotating shaft 32. The connecting end 341 is provided with a plurality of connecting holes 6 along the axial direction of the rotating shaft 32. The number of the connecting holes 6 on the rotating shaft 32 is equal to that of the connecting holes 6 on the connecting end 341, and the connecting holes 6 on the rotating shaft 32 and the connecting holes 6 on the connecting end 341 are in one - to - one correspondence. Internal threads are provided inside the connecting holes 6. Bolts pass through two mutually facing connecting holes 6 on the rotating shaft 32 and the connecting end 341 and are threadedly connected to the connecting holes 6, realizing the detachable connection between the dividing plate 34 and the rotating shaft 32.

[0040] Refer to Figures 3-5 , in the embodiment of the present application, the bottom of the dividing plate 34 does not contact the bottom surface of the crucible 2. The dividing plate 34 only abuts against the surface of the adjacent spacer 31 to support the spacer 31. In other embodiments of the present application, the sliding block 33 at the bottom can be cancelled. The bottom of the spacer groove 311 and the inner bottom surface of the crucible 2 are in the same plane, and the bottom of the dividing plate 34 is directly in contact with the inner bottom of the crucible 2, so that the space between adjacent spacers 31 can also be divided and isolated, improving the applicability.

[0041] When the partition plate 34 and the spacer plate 31 work in a high-temperature environment for a long time, it is inevitable that the spacer plate 31 and the partition plate 34 will crack. The user can remove the stopper 5 and the coolant interface 8 at the end of the driving screw 42 from the end of the driving screw 42, take out the spacer plate 31 and the partition plate 34 from the inside of the crucible 2 through the driving mechanism 4, replace the spacer plate 31, and then remove the bolts on the rotating shaft 32 and the partition plate 34 to replace the partition plate 34, reducing waste and improving the safety and working stability of this application. At the same time, when the user installs the spacer plate 31, the distance between adjacent two spacer plates 31 can be adjusted by adjusting the rotation speed of the driving motor 41, etc., to realize the adjustment of the distance between the spacer plates 31. However, when the distance between the two spacer plates 31 is too large, the partition plate 34 cannot play a supporting role. At this time, the user can rotate the rotating shaft 32 to place the partition plate inside the spacing groove 311, reducing the possibility of the partition plate shaking during processing.

[0042] Referring to the figure, a handle is provided at the top of the rotating shaft 32. In the embodiment of this application, the rotating shaft 32 can be made of a high-temperature resistant material such as graphite, reducing the probability of damage to the rotating shaft 32 at high temperatures. When the user adjusts the angle and position of the partition plate 34, the user can hold the handle and rotate it, or drive the sliding block 33 to move in the spacing groove 311 after holding the handle position, facilitating the user to adjust the angle and position of the partition plate 34.

[0043] Furthermore, in other embodiments of this application, the user can replace the handle with a motor, provide a mounting seat for installing a small motor on the spacer plate 31, coaxially and fixedly connect the output end of the motor to the top end of the rotating shaft 32 through a coupling to drive the rotating shaft 32 to rotate, realizing the angle adjustment of the partition plate 34, reducing the labor intensity of the user and improving work efficiency. At the same time, in order to reduce the possibility of damaging the motor, after the user adjusts the angle of the partition plate 34, the motor needs to be disassembled and separated from the rotating shaft 32, and then the spacer plate 31 and the partition plate 34 are installed inside the crucible 2 together by using the driving assembly.

[0044] Furthermore, extend the length of the rotating shaft 32 so that the top of the rotating shaft 32 extends out of the crucible 2, and install the motor on the top of the rotating shaft 32. At this time, the rotating shaft 32 is rotatably connected to the top of the crucible 2, reducing the possibility of damaging the motor when the crucible 2 is working. However, at this time, in order to ensure that the rotating shaft 32 can drive the partition plate 34 to realize the position change, a through groove needs to be opened at the top of the crucible 2. After changing the position of the partition plate 34, a square plug block is used to cover and install at the position of the through groove, reducing the heat loss of the crucible 2, or cancel the position change function of the partition plate 34, install the rotating shaft 32 at the middle position of the spacer plate 31, and only change the angle of the partition plate 34 when needed.

[0045] Further, in other embodiments of the present application, when the user changes the position of the partition plate 34, a motor and a screw parallel to the horizontal direction can be provided. The axis direction of this screw is parallel to the groove body direction of the spacer groove 311. The screw is also made of graphite material. The output end of the motor is coaxially fixedly connected to the end of the screw. An installation seat for installing a small motor is provided on the spacer plate 31. The output end of the motor is coaxially fixedly connected to the top of the screw by means of a coupling. At the same time, the screw passes through and is threadedly connected to the sliding block 33. When the motor is started, it drives the screw to rotate, so that the sliding block 33 moves inside the spacer groove 311, achieving the purpose of driving the rotating shaft 32 and the partition plate 34 to move, realizing the adjustment of the position of the partition plate 34, and realizing the division of the space between adjacent spacer plates 31. After the user adjusts the position of the partition plate 34, it is necessary to disassemble and separate the motor from the screw, reducing the damage of the crucible 2 to the motor, reducing the labor intensity at the same time, and improving the working efficiency of the user.

[0046] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
