Description
Technical field
The utility model relates to infrared ray heating tube technical fields, and in particular to a kind of infrared ray with double pipe structure adds
Heat pipe.
Background technique
Infrared electric-heating pipe is the tubular heater to be worked using infrared ray principle, as shown in Figure 1, existing red
Outside line heating tube generally by quartz ampoule 1,1 both ends of quartz ampoule and molybdenum sheet 3 with the molybdenum rod 2 that is connected with power supply are set, are arranged
Heating wire 4(in quartz ampoule 1 is also heater strip sometimes) it constitutes, it is evacuated in quartz ampoule, to protect heating wire 4 in vacuum
It can be long lasting for stable work in environment.
Although above-mentioned infrared electric-heating pipe structure is simple, low in cost, there is also following shortcomings:
(1) using mono-tube design, there are security risks, broken after quartz ampoule 1 bursts (generally blown and caused by heating wire 4)
Broken quartz-glass pieces are easy pollution heating object；(2) it is limited to the quartz ampoule 1 softening temperature (softening point of quartz glass
About 1730 DEG C of temperature, can be used for a long time at 1100 DEG C, short time maximum operation (service) temperature is up to 1450 DEG C) limitation, cannot
It is made into powerful heating tube.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of infrared ray heating tube with double pipe structure, with solution
The technical issues of polluting heating object after certainly existing infrared heating pipe explosion and high-power heating pipe cannot be made into.
The technology employed by the present utility model is
A kind of infrared ray heating tube with double pipe structure, including interior quartz ampoule, outer quartz ampoule and setting are designed described
Heating wire inside interior quartz ampoule, the outer quartz pipe sleeve is on the outside of the interior quartz ampoule, and the inside and outside quartz ampoule both ends are close
Seal so as to form a closed cavity between the two, the outer quartz ampoule be equipped with the cooling medium that is connected to the closed cavity into
Mouth and cooling medium outlet.
Preferably, the inside and outside quartz ampoule coaxial arrangement.
Preferably, the interior quartzy pipe outside diameter is 11~12mm, and wall thickness is 0.5~1.5mm, outer quartz pipe outside diameter is 25~
30mm, wall thickness are 1~2mm.
Preferably, the cooling medium outlet is set to the top of the outer quartz ampoule, the cooling medium inlet setting
In the lower part of the outer quartz ampoule.
Preferably, the inside and outside quartz ampoule is transparent quartz glass tube.
Compared with prior art, the advantageous effects of the utility model are:
1, inside and outside two layers of quartz ampoule is equipped in the utility model, after interior quartzy pipe explosion, broken quartz glass is wrapped
It wraps up in in outer quartz ampoule, to prevent pollution heating object, plays safeguard protection.
2, it is passed through transparent cooling medium in the closed cavity that the utility model is arranged between inside and outside two layers of quartz ampoule, passed through
Cooling medium reduces the temperature of quartzy pipe surface, prevents heating tube from softening, to make heating tube long-time under high power density
Continual and steady work is possibly realized；Cooling medium transparent simultaneously will not influence heating tube to the infrared hot spoke of heating object
It penetrates.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of existing infrared ray heating tube；
Fig. 2 is the structural schematic diagram of the utility model；
1 is quartz ampoule, and 2 be molybdenum rod, and 3 be molybdenum sheet, and 4 be heating wire, and 5 be interior quartz ampoule, and 6 be outer quartz ampoule, and 7 be confined air
Chamber, 8 export for cooling medium, and 9 be cooling medium inlet.
Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings and examples, but following embodiment only uses
It is described in detail the utility model, does not limit the scope of the utility model in any way.Involved in following embodiment
The devices such as unit module components, structure, mechanism are then unless otherwise instructed conventional commercial product.
Embodiment: as shown in Fig. 2, a kind of infrared ray heating tube with double pipe structure, including interior quartz ampoule 5, outer quartz
Pipe 6 and heating wire 4, heating wire 4 are set to inside interior quartz ampoule 5, and are electrically connected with the molybdenum sheet 3 of the both ends of interior quartz ampoule 5 setting,
With the molybdenum rod 2 for being connected with power supply on molybdenum sheet 3, the outer coaxial arrangement of quartz ampoule 6 is in interior 5 outside of quartz ampoule, interior 5 He of quartz ampoule
Outer 6 both ends of quartz ampoule carry out press seal so as to a closed cavity 7 be formed between interior quartz ampoule 5 and outer quartz ampoule 6, on outer quartz ampoule 6
Portion and lower part are respectively equipped with the cooling medium outlet 8 being connected to confined space 7 and cooling medium inlet 9.
In the present embodiment, interior quartz ampoule 5 and outer quartz ampoule 6 are transparent quartz glass tube, wherein interior quartz pipe outside diameter is
11~12mm, wall thickness are 0.5~1.5mm, and outer quartz pipe outside diameter is 25~30mm, and wall thickness is 1~2mm.
The operate with method of the above-mentioned infrared ray heating tube with double pipe structure is as follows:
The molybdenum rod 2 at heating tube both ends is electrically connected to a power source, 4 heating power of heating wire carries out infrared emanation with to being added
Hot object is heated, and (media such as water or air, transparent medium will not cause infrared radiation heating transparent cooling medium
Influence) enter closed cavity 7 from cooling medium inlet 9, after the heat for absorbing interior quartz ampoule 5 and outer quartz ampoule 6, from cooling medium
