Abstract

The invention discloses a thermal insulating device of a sapphire processing furnace. The thermal insulating device comprises a furnace body and a furnace cover connected to the top of the furnace body; a first thermal insulating layer is arranged on the outer wall of the furnace body and a second thermal insulating layer is arranged on the inner wall of the furnace body; a heater is arranged in the bottom of the furnace body; an insulation board connected with the heater is further arranged at the bottom of the furnace body. Therefore, the thermal insulating device of the sapphire processing furnace is of a multi-layer thermal insulating structure, and is capable of achieving good heat gathering and thermal insulation effects on material inside the furnace body and also capable of preventing the heat loss of the material inside the furnace body; as a result, crystal pollution can be reduced, the thermal insulation property can be stabilized, the heating efficiency is high, the heating process is clean, hot air conveying is not needed and secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of sapphire processing, in particular to a heat preservation device for a sapphire processing furnace. Background technique [0002] Sapphire has the advantages of high hardness, high melting point, good light transmission, excellent electrical insulation, and stable chemical properties. It is widely used in high-tech fields such as machinery, optics, and information. [0003] The processing methods of sapphire mainly include flame melting method, flux method and melt method, and are generally synthesized in a processing furnace. In the prior art, during processing of sapphire, due to the poor thermal insulation performance of the furnace body, it is easy to cause poor quality of processed gemstones. Contents of the invention [0004] The main technical problem to be solved by the present invention is to provide a heat preservation device for a sapphire processing furnace, which adopts a multi-layer heat ...
