[0031] At the same time, refer to Figure 3-4The 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. The output end of the driving motor 41 can be coaxially 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 top center of the partition plate 31. The driving screw 42 passes through and is threadedly connected to a plurality of moving blocks 312. The moving blocks 312 are slidably connected to the top of the crucible 2, so that the movement of the partition plate 31 is more stable, and the partition plate can be adjusted. The user places the material in front of the partition plate 31 when installing the partition plate 31, and then installs the adjacent partition plates 31 into the crucible 2, and adjusts the position of the adjacent partition plates 31 to achieve the division of the internal space of the crucible 2, while reducing the interaction between adjacent spaces, reducing the possibility of mutual contamination of materials, and improving the processing accuracy. At the same time, at least one ventilation hole can be opened on the top of the crucible 2 between adjacent partition plates 31 to achieve ventilation, improve the safety of the present application, and achieve the purpose of users processing multiple materials at the same time, while improving processing efficiency and saving resources.

[0032] Reference 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 . When the user has installed the partition plate 31, the driving motor 41 is turned off and the blocking member 5 is threadedly connected to the end of the driving screw 42 to reduce the possibility of the partition plate 31 slipping out of the crucible 2 and improve working stability and safety. At the same time, the driving screw 42 is provided with a cooling groove 421 along its own axial direction. Cooling holes 7 are provided at both ends of the driving screw 42. The blocking member 5 is provided with a cooling hole 7. The cooling hole 7 on the driving screw 42 and the cooling hole 7 on the blocking member 5 are interconnected. The cooling hole 7 and the cooling groove 421 are interconnected. The inner wall of the cooling hole 7 is provided with an internal thread.

The external coolant is connected to the cooling hole 7 and the inside of the cooling groove 421 to cool the driving screw 42, reduce the temperature of the driving screw 42, and reduce the damage of the driving screw 42 to the high temperature.

[0033] Reference Figure 3-5The partition plate 31 is slidably connected to the crucible 2 along the axial direction of the crucible 2 to achieve a stable connection of the partition plate 31. A partition groove 311 is provided on the surface of the partition plate 31. Each partition plate 31 is connected to two sliding blocks 33. One sliding block 33 is slidably connected to the top of the partition groove 311, and the other sliding block 33 is slidably connected to the bottom of the partition 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 top sliding block 33. The rotating shaft 32 The other end of the 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, so that the movement of the rotating shaft 32 is more stable. One end of the partition plate 34 is fixedly connected to the rotating shaft 32. When the rotating shaft 32 rotates, the other end of the partition plate 34 moves along the direction of the bottom of the groove close to or away from the spacing groove 311. The end of the partition plate 34 away from the rotating shaft 32 is attached to the adjacent spacing plate 31. The driving mechanism 4 is driven and connected to the spacing plate 31, and the spacing plate 31 moves along the axial direction of the crucible 2.

[0034] Reference Figure 3-5 One end of the dividing plate 34 is set as a connecting end 341, and the cross-section of the connecting end 341 is an arcuate surface. The connecting end 341 is arranged around and semi-surrounds the rotating shaft 32. The rotating shaft 32 is provided with a plurality of connecting holes 6 in a direction perpendicular to the axis, which increases the contact area between the connecting end 341 and the rotating shaft 32 and improves the stability of the connection. The plurality of connecting holes 6 are evenly arranged along the axis direction of the rotating shaft 32, and the connecting end 341 is provided with a plurality of connecting holes 6 along the axis direction of the rotating shaft 32. The number of connecting holes 6 on the rotating shaft 32 and the connecting end 341 is equal, and the connecting holes 6 on the rotating shaft 32 and the connecting holes 6 on the connecting end 341 correspond one to one. An internal thread is provided inside the connecting hole 6, and a bolt is inserted into two connecting holes 6 on the rotating shaft 32 and the connecting end 341 that are opposite to each other and is threadedly connected to the connecting hole 6, so as to realize the detachable connection between the dividing plate 34 and the rotating shaft 32.

[0035] Reference Figure 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 partition plate 31 to support the partition plate 31. In other embodiments of the present application, the sliding block 33 at the bottom can be eliminated, and the bottom of the partition groove 311 and the inner bottom surface of the crucible 2 are located in the same plane. The bottom of the dividing plate 34 is directly in contact with the inner bottom of the crucible 2, so that the space between the adjacent partition plates 31 can also be divided and isolated, thereby improving applicability.

[0036] When the partition plate 34 and the spacer plate 31 work for a long time in a high temperature environment, the partition plate 31 and the partition plate 34 will inevitably crack. The user can remove the blocking member 5 and the coolant interface 8 at the end of the driving screw 42 from the end of the driving screw 42, take the partition plate 31 and the partition plate 34 out of the crucible 2 through the driving mechanism 4, replace the partition plate 31, and then remove the bolts on the rotating shaft 32 and the partition plate 34, and replace the partition plate 34, thereby reducing waste and improving the safety and working stability of the present application. At the same time, when the user installs the partition plate 31, the user can adjust the spacing between two adjacent partition plates 31 by adjusting the speed of the driving motor 41, etc., to adjust the spacing between the partition plates 31. However, when the spacing between the two partition 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, thereby reducing the possibility of the partition plate shaking during processing.

[0037] Referring to the figure, a handle is set on the top of the rotating shaft 32. In the embodiment of the present application, the rotating shaft 32 can be made of high-temperature resistant materials such as graphite to reduce the probability of damage to the rotating shaft 32 at high temperatures. When the user adjusts the angle and position of the dividing plate 34, the user can hold the handle and rotate it, or after holding the handle, drive the sliding block 33 to move in the spacing groove 311, so that the user can adjust the angle and position of the dividing plate 34.

[0038] Furthermore, in other embodiments of the present application, the user can replace the handle with a motor, provide a mounting base for a small motor on the partition plate 31, and coaxially fix the output end of the motor to the top of the rotating shaft 32 using a coupling to drive the rotating shaft 32 to rotate, thereby adjusting the angle of the partition plate 34, reducing the user's labor and improving work efficiency. At the same time, in order to reduce the possibility of damage to the motor, after adjusting the angle of the partition plate 34, the user needs to disassemble and separate the motor from the rotating shaft 32, and then install the partition plate 31 and the partition plate 34 together inside the crucible 2 using a drive assembly.

[0039] Furthermore, the length of the rotating shaft 32 is extended so that the top of the rotating shaft 32 extends out of the crucible 2, and the motor is installed 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 damage to the motor when the crucible 2 is working. However, in order to ensure that the rotating shaft 32 can drive the dividing plate 34 to change its position, it is necessary to open a through groove on the top of the crucible 2. After changing the position of the dividing plate 34, a square block is used to cover and install it in the position of the through groove to reduce the heat loss of the crucible 2, or the position change function of the dividing plate 34 is canceled, and the rotating shaft 32 is installed in the middle position of the partition plate 31. The angle of the dividing plate 34 is changed only when necessary.

[0040] Furthermore, in other embodiments of the present application, when the user changes the position of the dividing plate 34, a motor and a screw parallel to the horizontal direction can be set. The axial direction of the screw is parallel to the groove direction of the spacing groove 311. The screw is also made of graphite. The output end of the motor is coaxially fixedly connected to the end of the screw. A mounting seat for mounting a small motor is provided on the dividing plate 31. The output end of the motor is coaxially fixedly connected to the top of the screw by a coupling. At the same time, the screw passes through and is threadedly connected to the sliding block 33. When the motor is started, the screw is driven to rotate, so that the sliding block 33 moves inside the spacing groove 311, thereby driving the rotating shaft 32 and the dividing plate 34 to move, achieving the position adjustment of the dividing plate 34, and achieving the division of the space between adjacent dividing plates 31. After adjusting the position of the dividing plate 34, the user needs to disassemble and separate the motor from the screw, thereby reducing the damage of the crucible 2 to the motor, while reducing the workload and improving the user's work efficiency.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
