Description

Technical Field

[0001] The utility model relates to the technical field of graphite crucibles, and more specifically to a graphite crucible used for purifying high-temperature gas in an Acheson graphitization furnace. Background Art

[0002] Graphite crucible is a kind of crucible made of graphite, clay, silica and wax stone. Graphite crucible uses natural flake graphite as the main raw material, and plastic refractory clay or carbon as a binder for processing. It has the advantages of high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life.

[0003] At present, common graphite powder heat treatment methods include the Acheson graphitization furnace heat treatment of graphite powder process. Graphite powder is placed in a graphite crucible and buried in parallel and upright in the conductive powder that can accommodate the Acheson furnace. The crucibles in the furnace are arranged in a rectangular shape of 4*30. When the power is turned on, the conductive powder around the crucible is heated, causing the crucible to be heated indirectly and eventually causing the graphite powder in the crucible to be heated indirectly. The graphite crucible is a cylindrical closed container with an opening at the top and a circular groove, which is sealed with a disc-shaped crucible cover. The process is easy to operate, but there are technical defects such as low energy utilization, unstable product quality and low production efficiency, which seriously affect the efficient industrial production of graphite powder heat treatment.

[0007] The slide plate adopts a circular plate structure, and the edge of the slide plate is matched with the inner wall of the crucible pot body.

[0008] The upper edge of the crucible pot body is provided with an arc-shaped groove.

[0009] An arc-shaped notch is arranged at the edge of the crucible cover, and the arc-shaped notch is matched with the circular arc-shaped groove.

[0010] The outer diameter of the crucible pot body is 600 mm, and the height of the crucible pot body is 1100 mm.

[0011] The side wall thickness and bottom thickness of the crucible pot body are both 50 mm.

[0012] The hole is a circular hole with a diameter of 200 mm.

[0013] The diameter of the sliding vane is 500 mm.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The holes at the bottom of the crucible pot body facilitate gas entry, which is conducive to the contact between gas and graphite powder and gas purification; the built-in sliding plate of the pot body, the size of the sliding plate matches the pot wall, and the edge is arc-shaped and can slide inside the pot wall to prevent the leakage of graphite powder during the heating of the crucible. At the same time, after the heating is completed, the crucible pot body is turned upside down, and the push rod can be inserted from the bottom hole to quickly push the product out, which is convenient for unloading and reduces related processes. The sliding plate is easy to replace after wear and saves costs. The arc groove is designed at the pot mouth, which fits with the inner and outer circles of the pot cover, meets the sealing requirements, and is convenient for positioning when the lid is closed. This crucible device can meet the processing requirements, while improving energy utilization, improving product quality and ensuring production efficiency, meeting the purpose of efficient production of graphite powder heat treatment.
