[0021] In this embodiment: the graphite green body roasting furnace is mainly divided into two parts: a workbench 1 and a roasting furnace 2. When the device is in use, the motor 122 is first started through the control panel 105. When the motor 122 drives the gear ring 112 to rotate counterclockwise through the driving gear 123, the multiple groups of unloading plates 106 move outward under the drive of the linkage gear 111. When the unloading plate 106 slides outward along the sliding cavity 101, the lifting gear 116 located on the right side of the unloading plate 106 will drive the top threaded rod 117 to rotate clockwise, and the lifting gear 116 located on the left side of the unloading plate 106 will drive the top threaded rod 117 to rotate counterclockwise, and at this time, the door plate 203 opens upward along the feeding channel 202. Then the staff will place the graphite green body on the unloading plate 106, and when the driving gear 123 drives the gear ring 112 to rotate clockwise, the unloading plate 106 slides inward along the sliding cavity 101. At this time, the lifting gear 116 located on the right side of the unloading plate 106 will drive the top threaded rod 117 to rotate counterclockwise, and the lifting gear 116 located on the left side of the unloading plate 106 will drive the top threaded rod 117 to rotate clockwise, and the door panel 203 will close downward along the feed channel 202.

[0022] See attached Figure 2 -Attached Figure 3 and attached Fig.11A mounting groove 119 is provided at the top of the inner rotating chamber 104 , and a mounting rail 118 is fixedly provided at the top of the lifting gear 116 , and the lifting gear 116 is rotatably arranged in the inner rotating chamber 104 through the mounting rail 118 .

[0023] In this embodiment, in order to make the lifting gear 116 drive the threaded rod 117 at the top to rotate, the lifting gear 116 is rotatably arranged in the inner rotating chamber 104 through the mounting rail 118. The threaded rod 117 is located at the center of the annular mounting rail 118.

[0024] See attached Figure 2 -Attached Figure 3 and attached Figure 8 The convex plate 107 is provided with a slot 108 that cooperates with the lifting gear 116 .

[0025] In this embodiment: when the lifting gear 116 rotates and the blanking plate 106 reciprocates, in order to avoid interference from the convex plate 107 on the blanking plate 106, a groove 108 structure is designed, and the depth of the groove 108 is the same as the depth of the installation groove 119.

[0026] See attached Figure 1 and attached Figure 8 A pressure relief valve 205 is also provided on the top of the roasting furnace 2, and a limit ring 208 is provided on the top of the pressure relief valve 205. A plurality of groups of protruding arms 209 are provided on the inner wall of the pressure relief valve 205, and a reset spring 210 is connected to the top of the protruding arm 209, and a moving block 211 is connected to the top of the reset spring 210; a plurality of groups of exhaust holes 212 are provided on the edge of the moving block 211, and a horizontal plate 213 is provided between the protruding arms 209, and a cylinder 214 cooperating with the moving block 211 is installed in the middle of the horizontal plate 213, and a sensor 215 is also installed at the bottom of one group of the protruding arms 209.

[0027] In this embodiment: during the roasting process, inert gas is injected into the roasting furnace 2 through the inflation device 206, and during the roasting process, the gas will expand and the pressure inside the roasting furnace 2 will also increase. In order to avoid the effect of the roasting effect caused by excessive pressure, a pressure relief valve 205 is also provided on the top of the roasting furnace 2. When the sensor 215 detects that the pressure reaches the critical value, the cylinder 214 will be closed, and the output end of the cylinder 214 will retract outward. The gas in the roasting furnace 2 will impact the moving block 211 outward, and under the impact of the airflow, the moving block 211 will move outward, and the exhaust hole 212 will be separated from the limit ring 208, and the gas will be discharged through the exhaust hole 212. As the airflow weakens, the moving block 211 will gradually move inward under the action of the reset spring 210. When the sensor 215 detects that the airflow intensity is weakened to a preset value, the cylinder 214 will be started, and the cylinder 214 will restore the moving block 211 to its original position and abut against its bottom. When the roasting is finished, the fan 124 will inflate the roasting furnace 2 and cool it down. At this time, the cylinder 214 will start again and release the pressure through the exhaust hole 212.

[0029] In this embodiment, in order to automatically drive the ring gear 112 to rotate, thereby realizing the loading and unloading of graphite, the output end of the motor 122 is connected to a driving gear 123 meshing with the ring gear 112 .

[0030] See attached Fig. 9 -Attached Fig.10 , opposite threads are formed on the threaded rods 117 on both sides of the sliding cavity 101.

[0031] In this embodiment: in order to ensure synchronous driving of the threaded seat 204, opposite threads are designed. When the lower plate 106 slides outward along the sliding cavity 101, the lifting gear 116 located on the right side of the lower plate 106 will drive the top threaded rod 117 to rotate clockwise, and the lifting gear 116 located on the left side of the lower plate 106 will drive the top threaded rod 117 to rotate counterclockwise, and the door panel 203 will open upward along the feed channel 202. When the lower plate 106 slides inward along the sliding cavity 101, the lifting gear 116 located on the right side of the lower plate 106 will drive the top threaded rod 117 to rotate counterclockwise, and the lifting gear 116 located on the left side of the lower plate 106 will drive the top threaded rod 117 to rotate clockwise, and the door panel 203 will close downward along the feed channel 202.

[0033] In this embodiment, in order to install the gear ring 112 and rotate it relative to the bottom of the workbench 1, a T-rail 113 and a T-slot 114 structure that cooperate with each other are designed.

[0034] See attached Figure 5 -Attached Figure 6 A fan 124 is disposed at the bottom of the workbench 1 , and an output end of the fan 124 is connected to a duct 125 disposed inside the roasting furnace 2 .

[0035] In this embodiment, after the roasting is completed, in order to quickly cool down the graphite, the air duct 125 is arranged inside the roasting furnace 2.

[0036] See attached Figure 1 An aeration device 206 is also installed on the workbench 1, and the aeration device 206 is connected to the interior of the roasting furnace 2 through an aeration pipe 207.

[0037] In this embodiment, in order to inject inert gas into the roasting furnace 2 and thus improve the roasting effect, an aeration device 206 is installed on the workbench 1.
