Vacuum melting device for non-oxide optical glass

Abstract

The invention discloses a vacuum melting device for non-oxide optical glass, and belongs to the technical field of glass production equipment. The device mainly solves the problems that the production yield and product stability are affected due to the fact that a rocking body is heavy, a motor consumes power and production abnormity is likely to appear when an existing rocking furnace rocks integrally. The vacuum melting device is mainly characterized in that a melting furnace comprises a furnace body, a heating element and a vacuum melting container, and a through hole is formed in one side of the furnace body; a rocking device is composed of a motor, a power conveyor belt, a rocking shaft and a rocking box; the rocking box is located inside the furnace body, the rocking shaft penetrates through the through hole, one end of the rocking shaft is connected with the rocking box, the other end of the rocking shaft is connected with one end of the power conveyor belt, the other end of the power conveyor belt is connected with the motor, and the vacuum melting container is installed inside the rocking box. The vacuum melting device has the advantages of improving the vacuum melting efficiency and being more stable in production and capable of lowering power consumption, and is mainly used for vacuum melting of non-oxide optical glass.

Description

technical field [0001] The invention belongs to the technical field of glass production equipment, in particular to a vacuum melting device for non-oxide optical glass. Background technique [0002] The existing general vacuum smelting technology is to put the raw materials into the smelting container (ampoules) after batching according to the formula, and then use a vacuum pump to pump the smelting container (ampoules) into a relative vacuum, and use rock swing method for homogenization during the smelting process carried out in a manner. In terms of swing furnaces, the prior art adopts the overall swing method of the swing furnace, but the overall swing method will not only increase the excess load, increase the power consumption of the motor, but also make the wires connected to the swing furnace body Or the brush is more easily damaged, that is, it is more likely to cause abnormal production, thereby affecting the yield rate and product stability of non-oxide optical gl...

Problems solved by technology

In terms of swing furnaces, the prior art adopts the overall swing method of the swing furnace, but the overall swing method will not only increase the excess load, increase the power consumption of the motor, but also make the wires connected to the swing furnace body Or the brush is more easily damaged, that is, it is more likely to cause abnormal production, thereby affecting the yield rate and product stability of non-oxide optical glass production. In addition, due to the limitation of wires or brushes, the swing angle of the existing swing furnace is 180° Within, the homogenization effect and production efficiency of glass are not high
