The utility model relates to a rationally, compact structure makes thermocouple and heating element become a whole through armor manufacturing process to make heating element endow new temperature monitoring function.
Description
The utility model relates to a kind of armored electric heater with integration of self temperature control and heating, belongs to the electric-heating technology field.
Existing armoured electric heating element; no matter be screw type; or orthoscopic; no matter be that power supply wiring is drawn at two or the single head lead-out wire; no matter be large diameter, still miniature all is to be processed into the armouring entity by heating wires, insulating material and outer steel pipe through combination, because effective protection of the outer tube that adapts with working medium and temperature; effective isolation of closely knit insulating material has guaranteed that electric wire used as the long-life of heater members.But produce a joule heat energy at electricity by heating wires, when reaching electrically heated purpose, the heating situation of heated medium such as heating-up temperature must be obtained by an other sleeving temperature measurement and control system, are difficult to realize the automatic monitoring of temperature.
The purpose of this utility model provides and a kind of thermocouple is built among the heating element, make thermocouple become as a whole by the armouring manufacturing process, thereby make heating element give the armored electric heater with integration of self temperature control and heating of new temp monitoring function with heating element.
The utility model is an armored electric heater with integration of self temperature control and heating, comprise metal tube, place the insulating packing in the metal tube, place two heating wire that be arranged in parallel in the insulating packing, one end of two heating wire links to each other in insulating packing, and the other end is connected with respectively draws the outer lead-in wire of metal tube, it is characterized in that also comprising simultaneously placing two thermocouple wires that be arranged in parallel in the insulating packing, one end of two thermocouple wires is weldingly connected in insulating packing, and the other end is drawn outside the metal tube.
Also can be provided with wiring cap on the metal tube of described heating wire and thermocouple wire exit.
Described heating wire shape can be Double-spiral or single-screw-rectilinear structure.
Described two heating wire can be that whole bending links to each other or two root beads connect continuous in insulating packing.
The sectional area of described electrical heating elements can be the 5-30 square millimeter.
The cross sectional shape of described electrical heating elements can be round or square, the square type.
The material of described heating wire can be nichrome or nickel silicon alloy etc., and the material of described insulating packing can be magnesia ceramics powder etc.
Described electrical heating elements can adopt the moulding of drawing formula compaction process.
During manufacturing, diameter certain standard type thermocouple wire together is assembled among the suitable magnesium oxide moulding porcelain bead together with heating wire, the steel pipe of then porcelain bead being packed into carries out the armouring compaction process, after carrying out the processing of sealing and end socket again, can obtain the armoured electric heating element of built-in thermoelectric idol, owing to be porcelain bead assembling processing so the temperature-sensitive point can be placed electrical heating elements end, rear end, middle part and other any position before.
The utility model is reasonable in design, compact conformation, special structure design and assembly technology thereof, can be in armoured electric heating element the built-in any standardized thermocouple in any position, what the electrical heating elements of this band built-in thermoelectric idol had kept original armoured electric heating element can be around, withstand voltage, antidetonation, long-life, characteristics easy to use.Simultaneously, obtained the temperature perceptional function not strengthening under the long-pending prerequisite of armouring body section, can obtain the operating state of heater element by the electromotive force output of thermocouple, even the temperature information of heated medium, for the operation of monitoring heater provides effective means, inconvenience and trouble that the temperature monitoring system temperature-sensing probe is installed have also been exempted.
Accompanying drawing has provided structural representation of the present utility model.
Fig. 1 is an overall structure cutaway view of the present utility model;
Fig. 2 is an A-A face structure cutaway view shown in Figure 1;
Fig. 3 is the structure cutaway view of single-screw described in the utility model-linear electrical heating elements.
Among the figure, 1 is heating wire, and 2 is insulating packing, adopts the magnesia ceramics powder; 3 is metal tube; 4 are lead-in wire; 5 is wiring cap, adopts pyroceram glue; 6 is thermocouple wire.
Below in conjunction with embodiment the utility model is further described:
Miniature armoured electric heating element with the outgoing wire at one end of making a built-in K type thermocouple is an example: diameter of section Φ 4mm, length 500mm, heating power 350W/220V.The Cr20Ni80 electric wire of Φ 0.19-0.21 is turned to the spiral external diameter less than 0.8 millimeter, spiral is apart from the spirality heating wire 1 of certain (deciding according to heating element length 500mm and heating power 350W), adopt Φ 0.7mm pure nickel wire to make cold junction lead-in wire 4, at the fine scolder of a kind of Ni-Cu more than 950 ℃ pure nickel lead-in wire 4 and heating wire 1 being implemented fine weldering with fusing point is connected, penetrate then in two holes of the four hole MgO porcelain bead insulating packings 2 that are not less than Φ 4mm, in other two holes, penetrate simultaneously a pair of K type thermocouple wire 6, reinstall in the stainless steel tube 3 that is not more than Φ 6 * 0.5mm, and after implementing the location, again through the circular hole drawing die, three passages are pulled to the circular cross-section of 4 millimeters of Φ, after 1050 ℃/10min annealing in process, press the telltale mark crop end subsequently, the argon arc welding sealing, fire resistant resin wiring cap 5 end sockets desired armored electric heater with integration of self temperature control and heating.
