Description
Technical field
The utility model belongs to technical field of analytical instruments, is related to applied to inserting oxygen inspector for zirconium oxide, especially
It is the furnace device for the Zirconia detector of sulfuric acid baking furnace gas detection.
Background technology
Inserting oxygen inspector for zirconium oxide heats in sulfuric acid baking furnace atmosphere, it is necessary to which tubular zirconium-oxide is put into electric furnace
Insulation, to ensure the accuracy of oxygen content measurement.Because the sulfur dioxide concentration for being calcined outlet of still is very high, also contain sulfur trioxide gas
The corrosive substance such as body and acid mist, so hot plate easily corrodes, the problems such as causing gas leakage, the damage of instrument detection part, make
The less reliable stabilization of oxygen content measurement, influence the continuous use life-span of Zirconia detector.
The content of the invention
The purpose of the present utility model is to during oxygen content measurement, reduce sulfur dioxide, sulfur trioxide, acid mist
And corrosion of other corrosive substances to hot plate, extend the service life of Zirconia detector；Meanwhile supported using lengthening
Design enables the deep enough test environment heating and thermal insulation of electric furnace, ensures the accurate reliable of oxygen content measurement.
Main technical schemes of the present utility model：For the furnace device of oxygen content determiner for zirconium oxide, it is characterized in that electric furnace
Device includes electric furnace shell, wrapping wire boiler tube, combustion chamber outer tube, ceramic gland, seal washer, transit joint screw, conductive supporting
Bar, ceramic spacer ring and ceramic wiring terminal；There is combustion chamber outer tube outside the wrapping wire boiler tube, have sealing gasket at combustion chamber exterior tubular zirconium-oxide
Enclose, have hole among ceramic spacer ring, conductive supporting bar is extended there through, fixed using bayonet lock.
Usually, the combustion chamber outer tube material is heat-stable ceramic.
The material of the seal washer is metallic graphite carbon.
The material of the conductive supporting bar is stainless steel, length 80-110cm.
The heating temperature range is at 550-750 DEG C.
Tubular zirconium-oxide and central tube are passed through among the electric furnace, electric furnace heats simultaneously to both.
The utility model has combustion chamber outer tube outside wrapping wire boiler tube, and material is heat-stable ceramic.Use ceramic powders plus glue
Gap between wrapping wire boiler tube and combustion chamber outer tube is tamped, electric furnace heating wire is sealed, then ceramic combustion chamber is filled with glass heat-insulating cotton
Gap between electric furnace shell, there is seal washer at combustion chamber exterior tubular zirconium-oxide, material is metallic graphite carbon.Electric furnace heating wire lead leads to
Cross ceramic gland with transition joint screw with stainless steel conductive supporting bar to be connected, the material of conductive supporting bar is stainless steel, length
For 80-110cm.There is ceramic spacer ring between conductive supporting bar, there is hole among ceramic spacer ring, conductive supporting bar extends there through, and uses
Bayonet lock is fixed.The another of conductive supporting bar is terminated on the screw of ceramic wiring terminal, is drawn hot plate lead, is connected to wiring
On box, operating personnel's wiring is facilitated to debug.Tubular zirconium-oxide and central tube are passed through among electric furnace, electric furnace adds simultaneously to both
Heat, heating temperature range is at 550-750 DEG C.
While the utility model realizes electric furnace to tubular zirconium-oxide heating and thermal insulation, overcome sulfur dioxide, sulfur trioxide,
Corrosion of the impurity such as acid mist to hot plate silk.Flue-gas temperature scope can be surveyed to widen significantly, anti-adverse environment ability is mentioned,
Oxygen content determiner for zirconium oxide is set more efficiently to work.
