Description
Technical field
This utility model relates to adding heat pipe field, particularly relates to a kind of electric heating tube.
Background technology
The operation principle of electrothermal tube is to produce heat after heating wire energising in metal tube, by the metal shell of electrothermal tube to
Heating target transmission heat.Existing heater specifically includes that and adds heat pipe, heater strip, magnesium oxide packed layer, and adding heat pipe is steel
Pipe, heater strip is located at and adds in heat pipe, for preventing electric leakage, heater strip not with add heat pipe inner wall and contact, mainly by being filled in heating
Magnesium oxide packed layer between pipe and heater strip insulate, and meanwhile, magnesium oxide packed layer also acts as the effect of heat conduction, this kind of side
The greatest problem that formula exists is: owing to the variation of material and the compaction rate of packed layer influence whether heat-conducting effect, make
The quality obtaining product is extremely difficult to best and unified, and to adding, thermal medium heating is slow.
Utility model content
Based on this, it is necessary to provide a kind of preferable electric heating tube of heat-conducting effect.
A kind of electric heating tube, including porcelain knob and electric heating tube body, described electric heating tube body one end is solid with described porcelain knob
Fixed connection, electric heating tube body includes outer steel pipe, quartz tube layer, heating wire and magnesia powder, and described quartz tube layer is positioned at described
Inside outer steel pipe, and the outer wall of described quartz tube layer is fitted with described outer steel pipe inner wall, and described heating wire is positioned at described quartz ampoule
The inside of layer, is filled with magnesia powder at described quartz tube layer inwall and described heating wire gap.
Wherein in an embodiment, also including two binding posts, described porcelain knob is provided with the through hole making binding post pass,
Heating wire upper end is connected with the lower end of two described binding posts.
Wherein in an embodiment, described heating wire is helical form heating wire.
Wherein in an embodiment, described heating wire is near described quartz tube layer inwall.
Above-mentioned electric heating tube, owing to steel pipe inner wall is provided with quartz tube layer, the heat conductivility of quartz tube layer and insulation outside
Performance is preferable, it is possible to significantly improve the thermal conduction effect of electric heating tube, and firing rate is faster, in hgher efficiency.

Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus protection domain of the present utility model is made apparent clearly
Define.
Referring to Fig. 1, a kind of electric heating tube, including porcelain knob 1 and electric heating tube body 2, electric heating tube body 2 one end and porcelain
Post 1 is fixing to be connected, and electric heating tube body 2 includes outer steel pipe 21, quartz tube layer 22, heating wire 23 and magnesia powder 24, quartz ampoule
Layer 22 is positioned at inside outer steel pipe 21, and the outer wall of quartz tube layer 22 is fitted with outer steel pipe 21 inwall, and heating wire 23 is positioned at quartz ampoule
The inside of layer 22, is filled with magnesia powder 24 at quartz tube layer 22 inwall and heating wire 23 gap.The heat transfer of quartz tube layer and absolutely
Edge performance is better than the performance of magnesia powder, it is possible to is preferably conducted by heat and heats, and reduces thermal loss.
Preferably, electric heating tube also includes two binding posts 3, and porcelain knob 1 is provided with the through hole making binding post 3 pass, heating
Silk 23 upper ends are connected with the lower end of two described binding posts.
Wherein, heating wire 23 is helical form heating wire.Heating wire 23 is near quartz tube layer 22 inwall.Heating wire 23 near but
Not contacting quartz tube layer 22 inwall, the heat that such heating wire 23 produces can be conducted by quartz tube layer 22 as soon as possible, adds
The thermal efficiency is higher.
The production process of above-mentioned electric heating tube is: quartz tube layer 22 overlapped outside on steel pipe 21 inwall, after in quartz tube layer
22 internal put into heating wire 23 and magnesia powder 24, carry out vibrating, draw molding, baking operation, by binding post 3 and heating wire 23
Upper end is welded to connect, after with casting glue, porcelain knob is connected fixing with electric heating tube body 2.
Above-mentioned electric heating tube, owing to steel pipe inner wall is provided with quartz tube layer, the heat conductivility of quartz tube layer and insulation outside
Performance is preferable, it is possible to significantly improve the thermal conduction effect of electric heating tube, and firing rate is faster, in hgher efficiency.
Embodiment described above only have expressed several embodiments of the present utility model, and it describes more concrete and detailed,
But therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, common for this area
For technical staff, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these all belong to
In protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
