Technical Field

The invention relates to the field of metal smelting, in particular to an observation window glass device.

Background

The vacuum electron beam furnace is a special metal smelting device for electron beam smelting; the high-purity metal refers to metal with purity of more than 99.9 percent by refining, and the vacuum electron beam furnace is a main device for refining and casting the high-purity metal.

In the prior art, the rotation of the observation window glass of the vacuum electron beam furnace generally utilizes a rotation transmission shaft to drive a rubber leather ring so as to rub the observation window glass to enable the observation window glass to rotate, however, because the surface of the observation window glass is smooth and the observation window glass is movable, the observation window glass is in contact with the transmission shaft by utilizing gravity, a gap exists between the observation window glass and the transmission shaft, so that the rubber ring on the transmission shaft cannot rotate the observation window glass frequently, further, the smelting work is directly interrupted, and great economic loss is caused.

Disclosure of Invention

According to the problems in the prior art, an observation window glass device is provided, and aims to provide a connection mode of an observation window glass and a rotating shaft so as to solve the problem that the observation window glass cannot rotate frequently due to a gap between the rotating shaft and the observation window glass.

The technical scheme specifically comprises the following steps:

an observation window glass device suitable for a vacuum electron beam furnace, comprising:

the rubber belt is arranged on the outer side of the observation window glass in a surrounding way;

the special leather ring is arranged on the outer side of a transmission shaft in a surrounding mode, is provided with a groove facing the rubber belt, the rubber belt is embedded into the groove, and when the transmission shaft rotates, the groove drives the rubber belt to rotate, so that the observation window glass rotates along with the transmission shaft.

Preferably, the rubber belt is a high-temperature resistant plastic belt.

Preferably, the adhesive tape is fixed on the observation window glass through high-temperature-resistant vacuum glue.

Preferably, the specially-made leather collar is a high-temperature-resistant plastic leather collar.

Preferably, the viewing window glass is lead glass.

Preferably, the method further comprises the following steps:

the connecting shaft is fixedly arranged at the centers of the observation window glass and the upper cover of the vacuum electron beam furnace and is used for connecting the observation window glass and the upper cover;

when the observation window glass rotates, the upper cover simultaneously rotates through the connecting shaft;

and the observation window is arranged on the upper cover.

Preferably, the diameter of the observation window is smaller than the observation window glass.

Preferably, the observation window is a through hole.

The technical scheme of the invention has the beneficial effects that: the invention uses the rubber belt, fills the gap between the observation window glass and the rotating shaft on the premise of not introducing pollution, thereby increasing the friction between the observation window glass and the rotating shaft, leading the rotating shaft to more easily drive the observation window glass to rotate, greatly reducing the possibility of the observation window glass, further ensuring the normal operation of smelting work, avoiding the large-area change of the vacuum electron beam furnace, and saving a large amount of funds and time.

The invention is further described with reference to the following drawings and specific examples, which are not intended to be limiting.

The present invention provides an observation window glass device suitable for a vacuum electron beam furnace, as shown in fig. 1 and 2, comprising:

the rubber belt 1 is arranged around the outer side of the observation window glass 2;

the special leather ring 3 is arranged on the outer side of the transmission shaft 4 in a surrounding mode, a groove 31 facing the rubber belt 1 is formed in the special leather ring, the rubber belt 1 is embedded into the groove 31, when the transmission shaft 4 rotates, the groove 31 drives the rubber belt 1 to rotate, and therefore the observation window glass 2 rotates along with the transmission shaft 4.

Specifically, the rubber belt 1 is a high-temperature resistant plastic belt.

Specifically, the rubber belt 1 is fixed on the observation window glass 2 through high-temperature-resistant vacuum glue.

Specifically, the rubber belt 1 is used for filling a gap between the observation window glass 2 and the transmission shaft 4 without introducing pollution, and increasing friction force.

Specifically, the specially-made leather collar 3 is a high-temperature-resistant plastic leather collar.

Specifically, the observation window glass 2 is lead glass.

The observation window glass device in the technical scheme has the following specific using process:

further, the driving shaft 4 is continuously rotated during the operation of the vacuum electron beam furnace.

Further, the special leather ring 3 arranged on the transmission shaft 4 rotates along with the transmission shaft 4.
