Abstract
The utility model relates to a zirconium-oxide heating element, which is mainly characterized in that the utility model is formed by that a leading wire body, heating end, the 'cold ' end of the heating body and a connecting body are assembled into the structure of a U-shaped heating element. The connecting body belongs to a heterotype structure having two taper holes. The heating end and the connecting body are tightly matched together by adopting a taper type, and high temperature ZrO2 slurry is filled between the heating end and the connecting body. The heating end, the 'cold ' end of the heating body and the wire leading body are all a thin-wall pipe. The heating element of the utility model has the advantages of the length of the heating end of the heating body stretching, the power of the heating element increasing, furnace construction simplifying, electric power consumption saving, convenient assembly and disassembly, being capable of using a closed type furnace bottom.
Description
The utility model belongs to heater element.Mainly be applicable to high-temperature heater etc. under the oxidizing atmosphere.
Along with the development of material science, day by day many specific harsh requirements have been proposed also its corresponding technology, under specific oxidizing atmosphere, carry out high temperature (as 1800 ℃) heat treatment as some material, to obtain property; For the material or the device of some no specific (special) requirements, what have can carry out sintering or heat treatment in air, and both safe and reliable, cost also reduces with the simplification of technology, thereby shows the glamour of using high temperature heat source under the oxidizing atmosphere more.
Zirconia matter heater element is under oxidizing atmosphere, and serviceability temperature is up to the heater more than 2000 ℃.It is the present the highest heater of serviceability temperature under oxidizing atmosphere.
At present, be used for the zirconia matter heater element of high-temperature heater, structurally major part is (the Chinese patent application CN92203760.4) of straight bar type.Because the great (5.7g/cm of ratio of zirconia ceramics
3About), elevated temperature strength is low, and high temperature easily generation creep down, so straight bar type zirconia matter heater element at high temperature easily deforms, the life-span is short.Zirconia matter heater element in the described ceramic heat stove of Japanese kokai publication hei 2-210785 is also taked the U type on the structure, but is whole U type structure, processing difficulties; In addition, its " lead-in wire body " adopts precious metal platinum, cost height.
The purpose of this utility model is to provide a kind of processing and manufacturing easy, and cost is low, and is out of shape little assembly type U type zirconia matter heater element.
Assembly type U type zirconia matter heater element described in the utility model is made up of heating end, heater " cold " end, lead-in wire body and connector.Heating end, heater " cold " end, lead-in wire body are light-wall pipe; Connector is abnormally-structured.The lead-in wire body is made by combined oxidation chromic acid lanthanum base pottery, and heating end, heater " cold " end, connector are by ZrO
2-CaO pottery is made.Four parts of above-mentioned heater element are processed respectively, are assembled into the zirconia matter heater element of U type then.
Compared with prior art, the utlity model has following advantage:
1, this assembly type U type zirconia matter heater element can prolong the length of heating end, increases power.
2, compare with the described U type of Japanese kokai publication hei 2-210785 heater element, resistance is more even, and production technology is simple simultaneously.
Be convenient to dismounting when 3, U type heater element uses.Simultaneously can simplify furnace binding (furnace bottom can adopt closed), reduce thermal loss, saves energy consumption.
Now the utility model is described in further detail in conjunction with the accompanying drawings.
Accompanying drawing 1 is the structural representation of a kind of zirconia matter of the utility model heater element.
Accompanying drawing 2 is the schematic diagram of connector 4.
Accompanying drawing 3 is the vertical section schematic diagram of connector.
Among Fig. 1 and 2,1 is the lead-in wire body, and 2 is heater " cold " end, and 3 are the heating end, and 4 is connector, and 5 is bellmouth.
Lead-in wire body 1 adopts with heater " cold " end 2 and is threaded.One end of heater " cold " end 2 has external screw thread, and lead-in wire body 1 has internal thread with heater " cold " end 2 ends that join, and both match by internal and external threads, link together.Lead-in wire body 1 also can adopt the inclined-plane to be connected with heater " cold " end 2.In above-mentioned two kinds of syndetons, all insert resistant to elevated temperatures ZrO in the junction
2Or LaCrO
3In slurry.
Find out that by Fig. 3 connector 4 is for having the specificity structure of two bellmouths.
Heating end 3 has with the connected mode of heater " cold " end 2: 1. tight fit is connected; 2. the inclined-plane connects; 3. step connects.
Heating end 3 adopts the cone type tight fit to be connected with connector 4, is filled with ZrO therebetween
2Slurry.Both not only are connected firmly, and contact-making surface is big, are beneficial to conduction.
Lead-in wire body 1, heater " cold " end 2, heating end 3 and connector 4 are connected to each other the back and form U type structure.
Claims (5)
1, a kind of zirconia matter heater element comprises lead-in wire body and heater, it is characterized in that it assembles into U type structure by lead-in wire body 1, heater " cold " end 2, heating end 3 with connector 4.
2, heater element according to claim 1 is characterized in that connector 4 is for having the abnormally-structured of two bellmouths.
3, heater element according to claim 1 is characterized in that 4 of heating end 3 and connectors adopt cone type to closely cooperate, and the junction is filled with ZrO
2Slurry.
4, heater element according to claim 1 is characterized in that heating end 3, heater " cold " end 2 and lead-in wire body 1 are light-wall pipe.
5, heater element according to claim 1, the body 1 that it is characterized in that going between is made by composite oxides chromic acid lanthanum base pottery; Heating end 3, heater " cold " end 2 and connector 4 are ZrO
2-CaO pottery is made.
