Description

A protective platform for high-temperature discharge of graphitized materials in a furnace

Technical Field

The utility model relates to the technical field of protection platforms, in particular to a protection platform for high-temperature discharge of graphitized materials in a furnace.

Background technique

Graphitization furnace is mainly used in the manufacturing process of graphite electrode. It is a high-temperature heat treatment equipment for the transformation of its molecular structure from amorphous carbon to graphite structure. The heat treatment temperature is as high as 2800 degrees or more. The currently used graphitization furnace is a horizontal internal string graphitization furnace. The horizontal internal string graphitization furnace occupies a large area and has a long production cycle, usually taking one week.

The existing patent with publication number CN216864856U proposes a protection platform, which prevents construction workers from falling from the outer edge of the protection platform body by setting a guardrail at the outer edge, thereby improving safety and construction efficiency. A plurality of fixing seats are set at the inner edge of the protection platform body, and a rotating assembly is screwed to the threaded hole of the fixing seat. By rotating the assembly, one end of the rotating assembly is brought close to and pressed against the pier body of the vase pier, thereby achieving stability of the protection platform on the pier body. However, the protection platform lacks adjustment of the platform height. When the operator needs to work at a high place, it needs to be disassembled and welded due to insufficient height. The operation is cumbersome, which increases the workload of the staff and reduces the application scope of the platform. In view of the above problems, we propose an improved and upgraded protection platform for high-temperature discharge of graphitized materials in a furnace.
