Description

Technical Field

[0001] The utility model relates to the technical field of graphite crucibles, and more specifically, to a lifting and transferring device for high-temperature graphite crucibles. Background Art

[0002] A graphite crucible is made of graphite, clay, silica, and wax stone. Its characteristics include high-temperature resistance, strong thermal conductivity, excellent corrosion resistance, and a long service life. Common methods for heat treating graphite powder include the Acheson graphitization furnace. The graphite crucible is filled with graphite powder and placed vertically in a conductive powder container that can accommodate the Acheson furnace. When electricity is applied, the conductive powder surrounding the crucible heats up, indirectly heating the crucible and ultimately the graphite powder within.

[0003] Graphite crucibles can reach temperatures exceeding thousands of degrees Celsius after heating. To save production time and improve product quality, the heated crucibles can be cooled directly before removal and packaging. However, the cooled crucibles still retain residual heat, and conventional methods typically rely on manual transport. This traditional method is not only inefficient, but the residual heat can also cause burns to operators, compromising safety. Utility Model Content

This lifting and transporting device can adjust its height according to the different heights of the conveyor platform and flexibly rotate according to the conveying direction, allowing it to transport high-temperature crucibles on conveyor platforms with different paths. It has the advantages of low failure rate, low energy consumption, and low cost.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:
