Cover plate glass platinum channel thermocouple device and manufacturing method thereof

Abstract

The invention discloses a cover plate glass platinum channel thermocouple device and a manufacturing method thereof. A thermocouple is extended and straightened and then is subjected to double-layer cladding, so the fact that the surface of the thermocouple is not corroded by harmful foreign matters is guaranteed, bending and distortion of the thermocouple in the cladding process can be effectively avoided, and the strength reduction of the thermocouple caused by bending and distortion of the thermocouple which is collided by external force is avoided; a mould with the structure the same as that of the cladded thermocouple is put into a thermocouple mounting hole, the lower half part in the thermocouple mounting hole is poured, and the mould is taken out after the lower half part pouring layer is coagulated; the cladded thermocouple is put on the lower half pouring layer in the thermocouple mounting hole, so the fact that the thermocouple is not damaged by extrusion is guaranteed, and the bending and distortion of the thermocouple in the pouring process is avoided; the cover plate glass platinum channel thermocouple device is fixed, stable and insusceptible to deformation through once pouring and fixing, and the extrusion force, generated by thermal expansion, of the platinum channel is counteracted by the cladding layer cladding the thermocouple.

Description

technical field [0001] The invention belongs to the field of cover glass production, and in particular relates to a cover glass platinum channel thermocouple device and a manufacturing method thereof. Background technique [0002] The main function of the platinum channel in the production process of the cover glass is to clarify, homogenize and cool the glass liquid, and provide qualified glass liquid to the next process; the cost of the platinum channel is high, the cost is expensive, and the number of thermocouples used on the channel is large Widely distributed, once damaged, it will affect the normal production process control. Therefore, the service life of the thermocouple on the glass channel has a certain far-reaching significance for the supply of qualified glass liquid to the downstream process. Due to the limitation of the existing manufacturing process, the thermocouple on the platinum channel is directly embedded in the platinum channel. The expansion of the c...

Problems solved by technology

[0002] The main function of the platinum channel in the production process of the cover glass is to clarify, homogenize and cool the glass liquid, and provide qualified glass liquid to the next process; the cost of the platinum channel is high, the cost is expensive, and the number of thermocouples used on the channel is large, Widely distributed, once damaged, it will affect the normal production process control

Therefore, the service life of the thermocouple on the glass channel has a certain far-reaching significance for the supply of qualified glass liquid to the downstream process. Due to the limitation of the existing manufacturing process, the thermocouple on the platinum channel is directly embedded in the platinum channel. The expansion of the channel body during the heating process is easy to damage the thermocouple caused by extrusion, and it is not easy to repair, so a new structure is urgently needed to protect the thermocouple on the platinum channel
