Description

Technical Field

[0001] The utility model relates to the technical field of graphite processing, in particular to a vibration platform. Background Art

[0002] Graphite crucibles offer advantages such as high-temperature resistance, strong thermal conductivity, excellent corrosion resistance, and a long service life. During high-temperature use, they exhibit a low coefficient of thermal expansion and a certain degree of strain resistance to rapid cooling and heating. They are also highly resistant to corrosion from acidic and alkaline solutions and possess excellent chemical stability, making them widely used in metal smelting and graphite carbonization. However, when filling a graphite crucible with granular or powdered materials, they require vibration to compact them, necessitating the use of a vibration platform to improve efficiency.

[0003] A Chinese patent discloses a charging vibration platform device (authorization announcement CN213445192U). This patented technology achieves an ideal vibration compaction effect for the graphite in the crucible on the platform by setting a vibration platform with a shock-absorbing effect and adjusting the vibration amplitude, frequency, and vibration time of the motor. This breaks the original graphitization enterprise's charging method of relying entirely on manual pounding of the crucible. It not only improves production efficiency and reduces production costs, but also solves the technical problem of unstable power supply to the graphitization furnace caused by inaccurate manual charging. However, it cannot automatically clamp the graphite crucible, which may cause the graphite crucible to shift or overturn during the vibration process. Utility Model Content
