Description

Technical Field

[0001] The utility model relates to the technical field of graphite experimental equipment, in particular to an experimental table for studying the anti-oxidation performance of a graphite crucible impregnation method. Background Art

[0002] Graphite crucibles are made of natural flake graphite as the main raw material and plastic refractory clay or carbon as a binder. They have the characteristics of high temperature resistance, strong thermal conductivity, good corrosion resistance and long service life. Since graphite crucibles are mainly used to smelt non-ferrous metals such as copper, brass, gold, silver, zinc and lead and their alloys, graphite crucibles need to undergo antioxidant performance tests.

[0003] Patent publication number CN211652473U, titled "Test Bench for Studying the Antioxidant Properties of Graphite Crucible Immersion Method," discloses a test bench for studying the antioxidant properties of graphite crucible immersion methods. The bench comprises a support, a container fixedly connected to the middle portion of the upper end of the support, an electric heating tube mounted on the inner wall of the container, a drain pipe disposed at the bottom end of the container, a horizontally disposed shaft rotatably connected within the container, a plurality of rods sleeved on the shaft, a drive mechanism connected to the shaft, and a partition disposed horizontally at the bottom end of the container, dividing the container into upper and lower spaces. The partition has a porous structure, and a stirring mechanism is disposed in the space below the partition. This utility model utilizes a container and rod combination for immersion. The container holds the impregnating agent, the rod is sleeved with the graphite crucible, and the rod is driven by the drive mechanism to rotate and gradually sink into the water, thereby preventing human contact with the impregnating agent. This patented technology has shortcomings in its actual application. After the graphite crucible enters the impregnant, it will produce a chemical reaction with the impregnant, which may produce harmful gases. The equipment was not protected during the impregnation experiment, resulting in its long-term operation affecting the health of the workers. Utility Model Content
