Galvanic couple protection structure and method for top of platinum channel cooling section

Abstract

The invention discloses a galvanic couple protection structure and method for the top of a platinum channel cooling section. The galvanic couple protection structure comprises a thermocouple filling layer, a special-shaped protection sleeve and a system filling layer. The special-shaped protective sleeve is arranged on the outer side of the thermocouple, the special-shaped protective sleeve is fixed on the cooling pipe body, a thermocouple filling layer is arranged between the special-shaped protective sleeve and the thermocouple, and grouting filling is carried out on the thermocouple filling layer; the special-shaped protective sleeve comprises a thermocouple wire vertical pipe and a base, the base is fixedly arranged on the cooling pipe body, a through hole is formed in the center of the base, the thermocouple penetrates through the through hole to be connected with the cooling pipe body, the thermocouple wire vertical pipe is fixed to the through hole of the base, and the system filling layer is arranged on the surface of the base and the surface of the cooling pipe body. And comprehensive independent isolation and sealing are carried out, so that the integrity of the thermo wire and the cooling flat tube and the comprehensive oxidation resistance of the thermo wire are realized.

Description

technical field [0001] The invention belongs to the technical field of substrate glass manufacturing, in particular to a galvanic couple protection structure and method at the top of a cooling section of a platinum channel. Background technique [0002] Substrate glass belongs to the field of high-temperature manufacturing, which requires different processes to process molten glass through various equipment, and there is a strict correspondence between different processes and temperatures, so temperature monitoring is very important. Thermocouple is a special temperature detection equipment. It converts the thermal electromotive force signal into the temperature value of the measured medium. Platinum rhodium thermocouple has the characteristics of high temperature measurement accuracy and high temperature resistance, and is widely used in the substrate glass industry. For the cooling section of the platinum channel, because it needs to have superior heat dissipation performa...

Problems solved by technology

Therefore, after the cooling flat tube of the empty tube partially collapses, it will drive the thermocouple to move downward, and the even wire itself is constrained by the filler, and finally the even wire cannot bear the stress caused by the collapse of the flat tube, and the root or even A break in the wire path, causing the thermocouple to fail
