Description
Technical field
It the utility model is related to infrared ray heating tube, specifically a kind of infrared heating for having glazing layer on heating wire surface
Pipe.
Background technology
Most infrared ray heating tube is for the advantage of price on the market, using transparent or semitransparent quartz glass as pipe
Shell, metal heating wire are as heater.Because quartz glass thermal resistance is big so that heat does not distribute not go out, the accumulation of pipe internal heat,
Cause script to be just exposed to the heating wire in the air of oxidation characteristic to be under hot environment, accelerate oxidation rate, generate heat
Silk resistance becomes big, and power is significantly decayed, and the life-span shortens therewith.To protect heating wire, the method for generally use is in pipe at present
Vacuumize, existing vacuumizing method is that pipe is burnt in outside by using flame, and the air thermal expansion of the inside flows out from vacuum port, this
Vacuumizing method one is not environmentally；Second, vacuum is inadequate, DeGrain；Third, cost of labor height.
Utility model content
In order to find the metal heating wire guard method that a kind of effect is more preferable, cost is lower, spy has invented a kind of heating wire
There is the infrared ray heating tube of glazing layer on surface, it is desirable to provide the infrared ray that a kind of power attenuation speed is slow, long lifespan, the thermal efficiency are high
Heating tube.
The technical scheme that the utility model solves above-mentioned technical problem is as follows：
A kind of infrared ray heating tube for having glazing layer on heating wire surface, including insulation end socket, electrode, heating wire, fixation
Support and quartz glass tube, the heating wire are metal heating wire；There is one layer of glazing layer on described metal heating wire surface；It is described
Glazing layer be any blackness.
Further, the quartz glass inside pipe wall is shiny surface or roughening face；
Further, the quartz glass pipe outer wall is shiny surface or roughening face；
Further, described roughening face shape is corrugated, trapezoidal；
Further, the quartz glass pipe outer wall or inwall have dyed layer；
Further, the dyed layer is any blackness.
The beneficial effects of the utility model are：There is one layer of glazing layer on metal heating wire surface, has on the one hand prevented metal hair
Heated filament is exposed in application environment, on the other hand causes the thermal radiation capability of heating wire to strengthen, while improving the thermal efficiency, more
It is important that enhancing the oxidation resistance of heating wire, power attenuation speed is reduced, the life-span of heating wire is improved, increases
The service life of infrared ray heating tube is added.Meanwhile glazing layer has electric insulation capacity, due to table between heating wire circle and circle
The presence of body glazing layer, prevented substantially traditional heating wire caused by a variety of causes turn-to-turn short circuit and burn out the phenomenon of heating wire.
Brief description of the drawings
Fig. 1 is the utility model structure diagram one；
Fig. 2 is the utility model structure diagram two；
Fig. 3 is the sectional view for the heating wire that the utility model has glazing layer.
Reference is as follows：
1st, insulate end socket, 2, electrode, 3, heating wire, 4, quartz glass tube, 5, glazing layer, 6, fixed support, 7, outer wall, 8,
Inwall, 9, dyed layer.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality
It is new, it is not intended to limit the scope of the utility model.
Case study on implementation 1：
As shown in figure 1, there is the infrared ray heating tube of glazing layer on a kind of heating wire surface described by the present embodiment, including it is exhausted
Edge end socket 1, electrode 2, heating wire 3 and quartz glass tube 4.Described heating wire 3 is metal heating wire.Described metal heating
There is one layer of glazing layer 5 in silk table face.The described blackness convergence 1 of glazing layer 5.
Described quartz glass inside pipe wall 8 is shiny surface.
Described quartz glass pipe outer wall 7 is shiny surface.
Glazing layer 5 is realized by glazing technique.
The beneficial effects of the utility model are：There is one layer of glazing layer on metal heating wire surface, has on the one hand prevented metal hair
Heated filament is exposed in application environment, on the other hand causes the thermal radiation capability of heating wire to strengthen, in the case of cost optimization
While improving the thermal efficiency, it is often more important that enhance the oxidation resistance of heating wire, reduce power attenuation speed, improve
In the life-span of heating wire, significantly increase the service life of infrared ray heating tube.Meanwhile glazing layer has electric insulation capacity,
Due to the presence of table body glazing layer between heating wire circle and circle, it is short traditional heating wire turn-to-turn caused by a variety of causes has been prevented substantially
Road and the phenomenon for burning out heating wire.This embodiment cost is low.
Case study on implementation 2：
As shown in figure 3, there is the infrared ray heating tube of glazing layer on a kind of heating wire surface described by the present embodiment.
Including insulation end socket 1, electrode 2, heating wire 3, fixed support 6 and quartz glass tube 4.Described heating wire 3 is gold
Belong to heating wire.There is one layer of glazing layer 5 on described metal heating wire surface.The described blackness convergence 1 of glazing layer 5.
