[0022] The lifting assembly is used to pull the cover plate 10 up and down, so that the cover plate 10 can use the two carrying rods 12 to pull the crucible placed on the fixed ring 13 into and out of the heating box 1 as needed. In this way, the crucible can be taken in and out of the heating box 1 more safely. The first electric push rod 6 can be used to adjust the height of the scraper 11, so that the scraper 11 moved down into the crucible can scrape off the graphite phase carbon nitride attached to the inner wall of the crucible under the traction of the first motor 8, making the subsequent unloading of graphite phase carbon nitride more convenient.

[0023] Among them, the lifting assembly includes a rectangular frame plate 14, which is fixedly installed on the heating box 1.

[0028] When in use, the crucible is placed on the fixing ring 13, a certain amount of urea is added to the crucible, the crucible is covered with a lid, the second motor 17 is started to drive the screw 15 to rotate, the screw 15 pulls the cover plate 10 downward in a screw transmission manner, so that the cover plate 10 blocks the inlet and outlet slots 2, and the crucible completely enters the interior of the heating box 1, the operation of the second motor 17 is stopped, and the electric heating wire 3 is enabled to heat the crucible. After a period of time, the preparation of graphite phase carbon nitride is completed, the electric heating wire 3 is turned off, and the graphite phase carbon nitride is cooled to room temperature. , operate the second motor 17 to drive the screw rod 15 to pull the cover plate 10 upward, so that the crucible cover extends out of the heating box 1, stop the operation of the second motor 17, and after removing the cover, operate the first electric push rod 6 to extend, so that the first electric push rod 6 pushes the scraper 11 to move downward into the crucible, and the first motor 8 pulls the scraper 11 to rotate, so that the scraper 11 scrapes off the graphite phase carbon nitride attached to the inner wall of the crucible, and the first electric push rod 6 pulls the scraper 11 to move up and down, and the blocky graphite phase carbon nitride can be broken up with the help of the scraper 11;

[0029] After the graphite carbon nitride is broken up and scraped off from the inner wall of the crucible, the first electric push rod 6 is controlled to pull the scraper 11 upward and then reset, the second electric push rod 19 is controlled to push the feed pipe 22 to move above the crucible, and the second motor 17 is continued to be controlled to pull the crucible upward, and the fan 23 is controlled to operate so that the fan 23 discharges the air inside the collecting tube 20.
