[0045] The present utility model provides an automated system for the incoming and outgoing of graphitized crucibles.

[0046] Please refer to Figure 1 , in an embodiment of the present utility model, the automated system for the incoming and outgoing of the graphitized crucible 1 includes a crucible 1, a first functional area 2, a second functional area 3, a charging area 4, and a conveying track 5. The first functional area 2 is used to clean and load the crucible 1 when it enters the site. The second functional area 3 is used to suck and clean the crucible 1 when it exits the site. The charging area 4 is provided with a graphitization furnace 41 and a lifting device 42. The conveying track 5 is provided with a parking position 51 for parking the crucible 1. The conveying track 5 sequentially passes through the first functional area 2, the charging area 4, and the second functional area 3. The lifting device 42 is used to move the crucible 1 between the graphitization furnace 41 and the parking position 51.

[0047] In this embodiment, the first functional area 2 is provided with a loading device and a plurality of cleaning devices. When the crucible 1 enters the site, the crucible 1 is fixed at the parking position 51 on the conveying track 5 and passes through a plurality of cleaning devices and the loading device along with the transportation track. The cleaning device has a high-pressure air nozzle or a mechanical brush, etc., and is used to thoroughly clean the inner and outer surfaces of the crucible 1 to ensure no impurities. The loading device automatically fills the carbon material into the crucible 1 precisely according to a preset program to complete the loading process. After the crucible 1 passes through the first functional area 2, the crucible 1 that has been cleaned and loaded continues to reach the charging area 4 along with the conveying track 5. The graphitization furnace 41 in the charging area 4 is used to place and heat the loaded crucible 1. It is an important place for the graphitization reaction and also the place with the highest temperature. The charging area 4 is also provided with a lifting device 42. The lifting device 42 can take out the crucible 1 from the parking position 51 and put it into the graphitization furnace 41, or take out the crucible 1 from the graphitization furnace 41 and place it on the parking position 51 according to a preset program or remote control.

[0048] After the production is completed and the resistance material and heat-insulating material in the graphitization furnace 41 are discharged, the lifting device 421 transports the crucible 1 in the graphitization furnace 41 to the parking position 51 on the crucible 1 conveying track 5. The crucible 1 enters the second functional area 3 along with the conveying track 5. The second functional area 3 is provided with a material suction device and a plurality of cleaning devices. When the crucible 1 exits the field, the cleaning device cleans the residual resistance material and heat-insulating material on the outer wall of the crucible 1, and then starts the material suction device to efficiently suck out the graphitized finished product in the crucible 1 and convey it to the next process or storage container through a closed pipeline. Subsequently, the cleaning device cleans the inner wall of the crucible 1 again to prepare for the next use. During this process, the operator only needs to monitor the operating status of the equipment and does not need to approach the crucible 1 with residual high temperature.

[0049] In this embodiment, by arranging the conveying track 5 to sequentially connect the first functional area 2, the charging area 4, and the second functional area 3, and the crucible 1 moves along with the conveying track 5, automatic cleaning, loading, furnace charging, discharging, material suction, and re-cleaning are realized. In this way, the production efficiency of the graphitization process is improved.

[0050] Specifically, please refer to Figures 4 to 5 , in an embodiment of the present utility model, the crucible 1 includes an upper cover 11 and a crucible body 12. A protrusion 121 and an annular groove 12a are formed on the outer bottom wall of the crucible body 12. The upper cover 11 is provided with a groove 11a that is snap-fitted with the protrusion 121 for realizing the stacking of the crucibles 1.

[0051] In this embodiment, the crucible 1 adopts a cylindrical structure and is divided into a crucible 1 and an upper cover 11 of the crucible 1. The upper cover 11 is provided with a groove 11a, and a protrusion 121 is provided on the outer bottom wall of the crucible body 12. When the crucibles 1 are stacked, the protrusion 121 of the upper-layer crucible 1 is inserted into the groove 11a of the lower-layer crucible 1. The thickness of the protrusion 121 is higher than the depth of the groove 11a. In order to prevent the protrusion 121 from being stuck with the groove 11a, the diameter of the protrusion 121 is slightly smaller than the diameter of the groove 11a. Compared with the open crucible 1 commonly used in the existing graphitization process, the crucible 1 of this embodiment has an upper cover 11 that can seal the crucible body 12, avoiding the pollution of raw materials by auxiliary materials, the product quality is controllable, preventing the leakage of materials in the crucible 1 from polluting the external space, without additional environmental protection equipment, and the material recovery rate is high; the crucible 1 of this embodiment can be stacked through the cooperation of the protrusion 121 at the bottom of the crucible body 12 and the groove 11a of the upper cover 11, saving the floor area.

[0052] In order to realize the movement of the crucible 1 between the graphitization furnace 41 and the parking position 51, please refer to Figures 8 to 9, in an embodiment of the present utility model, the lifting device 42 includes a lifting equipment 421, a first suspension rail 422 and a second suspension rail 423. The first suspension rail 422 is arranged along the length direction of the graphitization furnace 41, and the second suspension rail 423 is arranged along the width direction of the graphitization furnace 41. The first suspension rail 422 is connected to the second suspension rail 423. The lifting equipment 421 includes a sliding seat 4211, a lifting connecting rod 4212 and a bracket 4213. The sliding seat 4211 is slidably arranged on the first suspension rail 422. The lifting connecting rod 4212 is arranged along the height direction of the graphitization furnace 41. One end of the lifting connecting rod 4212 close to the sliding seat 4211 is connected to the sliding seat 4211, and the other end of the lifting connecting rod 4212 far from the sliding seat 4211 is rotatably connected to the bracket 4213. The bracket 4213 abuts against the bottom wall of the annular groove 12a.

[0053] In this embodiment, a driving device and a braking device are arranged in the sliding seat 4211, which can realize the movement of the sliding seat 4211 on the suspension rail and the positioning on the graphitization furnace 41. The top end of the lifting connecting rod 4212 is connected to the sliding seat 4211. The lifting connecting rod 4212 can be set as a hydraulic rod or a rack rod, and the lifting connecting rod 4212 is used to drive the crucible 1 to rise or fall. The bracket 4213 is rotatably connected to the bottom end of the lifting connecting rod 4212. When the crucible 1 is arranged at the parking position 51, the protrusion 121 abuts against the parking position 51, and the annular groove 12a is completely exposed. The bracket 4213 rotatably extends into the annular groove 12a and abuts against the bottom wall of the annular groove 12a to realize the grasping of the crucible 1. The first suspension rail 422 is arranged along the length direction of the graphitization furnace 41, and the second suspension rail 423 is arranged along the width direction of the graphitization furnace 41, and is perpendicular and crossed with the first suspension rail 422. The lifting equipment 421, the first suspension rail 422 and the second suspension rail 423 form a three-dimensional movement system, which realizes the movement and positioning of the crucible 1 between the graphitization furnace 41 and the parking position 51.

[0054] The traditional way of lifting the crucible is to clamp the side wall of the crucible by a fixture for lifting. In this way, it is easy to cause the side wall of the crucible to be damaged, affecting the secondary use. Different from the traditional way of lifting the crucible, the crucible 1 in this embodiment is lifted by the lifting equipment 421. When lifting, the bracket 4213 holds up the bottom of the crucible, improving the way of lifting the crucible 1 when loading and unloading, avoiding the most vulnerable side wall of the crucible 1 from being extruded by external force and cracked, and increasing the number of times the crucible 1 can be reused.

The first cleaning area 22 is provided with a cleaning device that can extend into the crucible body 12 for cleaning the inner wall of the crucible 1. The loading area 23 is provided with a loading device for conveying the graphitized raw material from the material storage tank into the crucible 1. The first capping area 24 is provided with an automatic capping device for installing the upper lid 11 on the crucible body 12.

[0057] When the crucible 1 enters the site, the crucible 1 is fixed at the parking position 51 on the conveying track 5 and successively enters the first lid-opening area 21, the first cleaning area 22, the loading area 23, the first capping area 24, and the second cleaning area 25 along with the transportation track. Finally, it is transported into the graphite furnace 41 body by the lifting device 42. In this way, through the cooperation of the mechanical equipment in each area of the first functional area 2, the crucible 1, and the conveying track 5, the automation of the operations of opening the lid, cleaning the inner wall, loading materials, capping, and cleaning the outer wall of the crucible 1 is realized, improving the production efficiency.

[0059] In this embodiment, a cleaning device capable of cleaning the outer wall of the crucible 1 is provided in the third cleaning area 31 to prevent the heat-insulating material and resistance material remaining on the outer wall of the crucible 1 from mixing into the product and affecting the product quality. An automatic lid-opening device is provided in the second lid-opening area 32 to remove the upper lid 11 from the crucible body 12 by means of negative pressure suction or clamping.
