Clamping groove type graphite thin crucible for preparing silicon carbide powder
By setting an arc-shaped plug structure at the bottom of the graphite crucible cover and adding elastic inserts between the graphite crucible cover and the left and right crucibles, the problem of powder leakage caused by the separation of crucibles during the preparation of silicon carbide powder is solved, and a more stable lifting process and higher production efficiency are achieved.

AI Technical Summary
Technical Problem
During the preparation process of silicon carbide powder, the thin crucible built-in in slotted graphite is prone to be separated in advance due to uneven pulling force during the lifting process, which leads to leakage of silicon carbide powder, which increases the difficulty and risk of operation.
Method used
By setting an arc-shaped interposer structure at the bottom end of the graphite crucible cover and adding elastic inserts between the graphite crucible cover and the left and right crucibles, we ensure that the left and right crucibles will not separate during the lifting process.
Benefits of technology
It effectively avoids leakage of silicon carbide powder, simplifies operating procedures, improves production efficiency, and reduces the risks of operators.

Abstract
The utility model discloses a clamping groove type graphite thin crucible for preparing silicon carbide powder, which comprises a right bayonet type built-in thin crucible and a left bayonet type built-in thin crucible which is arranged on the outer wall of one side through a double-column calibration plug-in structure and a bayonet butt joint structure, the right bayonet type built-in thin crucible and the left bayonet type built-in thin crucible form a columnar graphite thin crucible, a left graphite semi-ring and a right graphite semi-ring are respectively fixed at one end inside the right bayonet type built-in thin crucible and one end inside the left bayonet type built-in thin crucible, and the left graphite semi-ring and the right graphite semi-ring are used for forming an annular piece. According to the utility model, the left thin crucible and the right thin crucible are limited through the arc-shaped plug-in structure at the bottom end of the graphite crucible cover, so that the left crucible and the right crucible cannot be separated in the lifting process, and the leakage of silicon carbide powder is avoided.
