Description

Technical Field

[0001] The utility model relates to the technical field of graphite carbonization, and particularly relates to a spliced crucible. Background Art

[0002] In the carbonization process of graphite powder, a graphite crucible is used as a carrier. The traditional graphite crucible adopts a graphite core-out process, which wastes a lot. Moreover, when one side or one corner of the graphite crucible is damaged, the whole crucible cannot be used continuously, resulting in a short service life of the crucible and a high use cost. Therefore, the research on spliced crucibles is becoming increasingly extensive. Currently, some spliced crucibles usually adopt the method of adding side plate connectors inside the crucible, but this will reduce the loading capacity of the crucible and the output. Or, some existing spliced crucibles adopt a trapezoidal tenon-mortise structure for splicing. After long-term use, the strength of this kind of crucible will decrease, and even large gaps will appear, resulting in the loss of the crucible structure's function. Summary of the Utility Model
