Internal flush type；Such heater form heating wire fixation, even if heating wire softening at high temperature will not deform,
Trigger short circuit.But the heating wire of such heater form is embedded in inside ceramic fibre, it is around heating wire coil and intermediate
Entirely insulating layer, due to only exposing 5%~10% part, outside radiations heat energy it is less able, thermal reservoir is being protected
Inside warm layer, cause actual power lower than design power；On the other hand, such heater form radiant heat transfer is slow, insulating layer
Internal heating wire temperature is excessively high, generally can be 200~250 DEG C higher than actual in-furnace temperature, easily fuses, even if not fusing the service life
Also can shorten；Moreover, the internal temperature of insulating layer is excessively high, the temperature resistant grade requirement of insulating layer is become higher, improves cost.
Another heater form：It is to slot on ceramic fibre part, such mode bearing is easy, and it is convenient to replace；Heat dissipation
Property it is good, heating wire only about 150 DEG C higher than in-furnace temperature or so, service life is relatively longer；Simultaneously as all heating wire are
It exposes in air, therefore radiant heat transfer is fast.But the heater form heating wire of such form is not fixed well, easily
It is subjected to displacement, pops up, short circuit etc.；Moreover, only can be used in siege position, side wall and top can not be used, and make for a long time
With due to not fixing, electric heating deformation of filament can be caused.
Utility model content
The utility model can not only have mainly solving the technical problems that providing a kind of ceramic fibre one heating module
The position of the fixed heating wire of effect, and thermal diffusivity is good, and the thermal efficiency is high, can make at other positions such as siege, furnace wall, furnace roof
With, under high temperature heating wire will not softening transform, service life is significantly improved than aforesaid way.
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of ceramic fibre one is provided

Width is 0.5~0.6 times of heating wire spiral winding diameter, and the embedded ceramic wool insulation layer of each heating wire is interior and electric
The identical depth of heated filament diameter, the heating wire is apart from the position of 5mm below inlay card slotted openings.
Preferably, the quantity at least two of the inlay card fluting, the adjacent inlay card are mutually parallel between slotting.
Preferably, the length of the inlay card fluting is less than the length of the ceramic wool insulation layer, and inlay card is in corresponding inlay card
Heating wire one end in fluting is pierced by from ceramic wool insulation layer one side.
Preferably, the one side of the ceramic wool insulation layer in the width direction is provided with electrode bar, the electrode bar insertion
One end of ceramic wool insulation layer is provided with inlay card hole, and the heating wire is inserted into corresponding inlay card hole.
Preferably, the ceramic wool insulation layer uses silicic acid aluminium material.
The beneficial effects of the utility model are：
1. heating wire is in the spiral coil of inner hollow, internal no insulating layer prevents heat from coming out, electric heating
Silk thermal diffusivity is good, and the thermal efficiency is high, and heating wire only can be about 150 DEG C higher than in stove, and service life is relatively longer.
2. 5mm below heating wire embedment ceramic wool insulation layer, is slotted by the inlay card of setting and is communicated with outside, heated
Object can be directly placed on ceramic wool insulation layer, without being contacted with heating wire.
3. in heating wire insertion ceramic wool insulation layer, insert depth is the diameter of heating wire, strong with very high fixation
Degree at high temperature, phenomena such as heating wire will not deform because of softening, ensure that the security reliability of heating wire.
4. can use at any position, including siege, furnace wall, furnace roof etc., its use scope has effectively been widened.
