[0002] Graphite powder purification refers to the process of removing impurities in graphite powder through a series of physical or chemical methods to improve its purity and performance. Physical purification of graphite generally involves putting graphite powder into a purification furnace, then evacuating the furnace, introducing inert protective gas and purification gas, and heating to 2800 degrees Celsius to volatilize impurities and other elements in the graphite.

[0003] At present, graphite powder is generally discharged from a discharge pipe at the bottom of a purification furnace after high-temperature purification is completed. A valve for controlling the on-off of the discharge pipe is provided on the discharge pipe, but the valve is a certain distance away from the bottom of the purification chamber of the purification furnace. This results in part of the graphite powder remaining in the discharge pipe when the purification furnace purifies the graphite powder and cannot be completely purified. In order to prevent the graphite powder from accumulating inside the pipe, a discharge device for a high-purity graphite preparation furnace is proposed. Utility Model Content

The powder purification chamber 2 is connected. When the adjustment part drives the mounting rod 4 to descend, the blocking head 5 descends to block the discharge pipe 3. The adjustment part includes a mounting block 11 fixedly mounted at the bottom of the mounting rod 4. A circular hole 12 is opened in the mounting block 11.
