Abstract

The utility model discloses a heatproof and anticorrosion composite ceramic thermocouple, and the structure of the thermocouple comprises a thermode, and a protective sleeve which is used for sleeving the thermode. The key point lies in that the structure of the protective sleeve comprises an alumina-ceramic inner layer, and a silicon nitride ceramic outer layer disposed at the periphery of the alumina-ceramic inner layer. The above structure prolongs the service life of the thermocouple, improves the stability and accuracy of measurement, reduces cost, and improves benefits.

Description

A kind of heat-resistant anticorrosion composite ceramics thermopair
Technical field
The utility model belongs to temperature measuring device field, relates to a kind of thermopair, specifically a kind of heat-resistant anticorrosion composite ceramics thermopair.
Background technology
At present, for the temperature thermocouple on all-oxygen combustion kiln arch top by platinum-rhodium wire, corundum sleeve pipe, additional platinum sleeve pipe forms, and for sensitive measurement kiln temperature in real time, cannula tip need to be inserted to kiln inside, and end is contacted with flame space.Yet it is serious that the outermost platinum sleeve pipe of thermopair is corroded by the complex environments such as the high-temperature oxydation in kiln, very easily damaged, antioxidant anticorrosive not, after using a period of time, there is breakage, can cause the fluctuation of thermopair indicating value, directly affect the accuracy of measurement of thermopair.
Summary of the invention
In order to strengthen the heat-resistant anticorrosion of thermopair; designed a kind of heat-resistant anticorrosion composite ceramics thermopair; the utility model thermocouple protective casing internal layer is aluminium oxide ceramics; skin is silicon nitride ceramics; extended the serviceable life of thermopair; improve stability and the accuracy of measuring, reduced cost, improved benefit.
The technical solution of the utility model is: a kind of heat-resistant anticorrosion composite ceramics thermopair; structure comprises the protective casing that thermode and suit thermode are used, and key is: the structure of described protective casing comprises aluminium oxide ceramics internal layer and is arranged at the silicon nitride ceramics skin of aluminium oxide ceramics internal layer periphery.
The beneficial effects of the utility model are: 1, utilize the good characteristic of silicon nitride ceramics fire-resistant oxidation resistant and toughness, using it as skin, strengthened the heat-resistant anticorrosion type of thermopair, extended the serviceable life of thermopair; 2, between aluminium oxide ceramics internal layer and silicon nitride ceramics skin, alumina fibre middle layer is set, can makes aluminium oxide ceramics internal layer 2 coordinate closely with silicon nitride ceramics outer 4.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In accompanying drawing, the 1st, thermode, the 2nd, aluminium oxide ceramics internal layer, the 3rd, alumina fibre middle layer, the 4th, silicon nitride ceramics is outer.
Embodiment
A kind of heat-resistant anticorrosion composite ceramics thermopair; structure comprises the protective casing of thermode 1 and suit thermode 1 use, and key is: the structure of described protective casing comprises aluminium oxide ceramics internal layer 2 and is arranged at the silicon nitride ceramics skin 4 of aluminium oxide ceramics internal layer 2 peripheries.
Between aluminium oxide ceramics internal layer 4 and silicon nitride ceramics skin 5, be also provided with alumina fibre middle layer, when coordinating between silicon nitride and aluminium oxide ceramics when not fine and close, available alumina fibre fills, and makes it to coordinate closely.
During concrete enforcement; platinum rhodium thermode 1 is installed in the protective casing tube chamber of tubular thermopair, and protective casing internal layer is aluminium oxide ceramics layer, works to prevent matrix oxidation; skin is silicon nitride ceramics layer; rise and increase structural strength, corrosion-resistant, resistance to oxidation; resistant to elevated temperatures effect; when coordinating between silicon nitride and aluminium oxide ceramics when not fine and close, available alumina fibre fills, and makes it to coordinate closely.
