Abstract

The invention discloses an observation window glass device. The observation window glass device comprises a rubber belt, a special leather ring, observation window glass, a transmission shaft, a connecting shaft and an observation window. The technical scheme of the invention has the beneficial effects that the rubber belt is used, and a gap between the observation window glass and the transmission shaft is filled on the premise of not introducing pollution, so that the friction between the observation window glass and the transmission shaft is increased, the transmission shaft can drive the observation window glass to rotate more easily, and the possibility of non-rotation of the observation window glass is greatly reduced, so that the normal operation of smelting is ensured; and in addition, according to the technical scheme, large-area modification of a vacuum electron beam furnace is avoided, and a large amount of capital and time are saved.

Description

technical field [0001] The invention relates to the field of metal smelting, in particular to an observation window glass device. Background technique [0002] Vacuum electron beam furnace is a special metal smelting equipment for electron beam smelting; high-purity metal refers to the metal whose purity reaches more than 99.9% through refining, and vacuum electron beam furnace is a main equipment for refining and casting high-purity metal . [0003] In the prior art, the rotation of the observation window glass of the vacuum electron beam furnace is generally to use the rotating transmission shaft to drive the rubber apron to rub the observation window glass to make the observation window glass rotate. However, due to the smooth surface of the observation window glass and the The observation window glass is movable, and using gravity to make the observation window glass contact with the transmission shaft will cause a gap between the two, which will cause the rubber ring o...
