Description
Technical field
The utility model relates to a kind of heating element, is specifically related to a kind of heating tube.
Background technology
As everyone knows, heating tube connects after electricity, electric energy conversion can be become to heat energy, due to its low price, easy to use, pollution-free, is widely used in various heating occasions.At present, the heating tube that applies to metal processing and manufacturing industry is generally arranged in a plurality of U-shaped pipes by the metal tube that multiply resistance wire twisted wire is housed, and then, by the interface of each U-shaped pipe and heat-transfer pipe welding, heat-transfer pipe is connected with plug through insulator.Its shortcoming is because the resistance of the weld of the interface of U-shaped pipe and power supply tube connector is less, therefore cause by electric current excessively, the resistance wire in U-shaped pipe easily burnt out.Greatly reduced the useful life of heating tube.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of heating tube, overcomes above-mentioned defect, by the transformation to U-shaped pipe, makes the current stabilization passed through in pipeline, and protective resistance silk extends useful life of heating tube, reduces production costs.
For solving the problems of the technologies described above, the utility model provides a kind of heating tube, comprise plug, insulator, metal tube, resistance wire and heat-insulating block, in described metal tube, be provided with resistance wire, described metal tube is spirally wrapped around on described heat-insulating block, described metal tube connects described insulator, and described resistance wire is connected with plug through described insulator.
As a kind of preferred version of a kind of heating tube described in the utility model, the number of described heat-insulating block is a plurality of.
As a kind of preferred version of a kind of heating tube described in the utility model, between described adjacent two described heat-insulating blocks, be interference fit.
As a kind of preferred version of a kind of heating tube described in the utility model, between described adjacent two described heat-insulating blocks for being threaded.
As a kind of preferred version of a kind of heating tube described in the utility model, the material of described heat-insulating block is asbestos.
As a kind of preferred version of a kind of heating tube described in the utility model, described insulator is flange.
As a kind of preferred version of a kind of heating tube described in the utility model, described insulator is quartz material.
Compared with prior art, a kind of heating tube the utility model proposes, by the transformation to U-shaped pipe, makes the current stabilization passed through in pipeline, has protected resistance wire, has extended the useful life of heating tube, has reduced production cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.Wherein,
Fig. 1 is the perspective view of a kind of heating tube of the present utility model.
Wherein: 1 is that plug, 2 is that insulator, 3 is that metal tube, 4 is heat-insulating block.
Embodiment
A kind of heating tube described in the utility model, it comprises: plug 1, insulator 2, metal tube 3, resistance wire (not shown) and heat-insulating block 4, in described metal tube 3, be provided with resistance wire, described metal tube 3 is spirally wrapped around on described heat-insulating block 4, described metal tube 3 connects described insulator, and described resistance wire is connected with plug 1 through described insulator 2.
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with embodiment, the utility model is described in further detail.
First, herein alleged " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model.Different local in this manual " in one embodiment " that occur not all refer to same embodiment, neither be independent or the embodiment mutually exclusive with other embodiment optionally.
Secondly; the utility model utilizes structural representation etc. to be described in detail; when the utility model embodiment is described in detail in detail; for ease of explanation; the schematic diagram that represents heating-pipe structure can be disobeyed local amplification of general ratio work; and described schematic diagram is example, it should not limit the scope of the utility model protection at this.The three dimensions that should comprise in addition, length, width and the degree of depth in actual fabrication.
Embodiment mono-
Refer to Fig. 1, the perspective view that Fig. 1 is a kind of heating tube of the present utility model.As shown in Figure 1, described a kind of heating tube, it comprises: comprise plug 1, insulator 2, metal tube 3, resistance wire (not shown) and heat-insulating block 4.
In described metal tube 3, be provided with resistance wire, described metal tube 3 is spirally wrapped around on described heat-insulating block 4, and described metal tube 3 connects described insulator 2, and described resistance wire is connected with plug 1 through described insulator 2.
Its operation principle is: when power connection plug 1, electric current imports in resistance wire by plug 1, and when electric current is when the resistance wire, electric current work done and consume electric energy, has produced heat, and heat dispels the heat by metal tube 3, produces thermal effect.
In one embodiment, in order to adapt to the heating surface (area) (HS requirement of the metal of required heating, the number of described heat-insulating block 4 is a plurality of.Described a plurality of heat-insulating block 4 links together, and described metal tube 3 is wrapped on these a plurality of heat-insulating blocks 4, and described metal tube 3 is one, without cutting off.
For the ease of making described heat-insulating block 4 repeat rationally to utilize, between adjacent two described heat-insulating blocks 4, be interference fit.
In another embodiment, also can be for being threaded between adjacent two described heat-insulating blocks 4.
In addition, the material of described heat-insulating block 4 is asbestos, and such design is because of metal tube 3 excess Temperatures, to cause heat-insulating block burning accidents caused in order to prevent.
Heating tube in actual use often can with other equipment connections, or fix with other planes, so, described insulator 2 is designed to form of flanges, like this can be so that be connected and fixed with other equipment or plane.
Because quartz is a kind of highly stable material, fusing point, boiling point are higher, are difficult for reacting with other materials generations, therefore described insulator can be selected quartz material.
What the those of ordinary skill in affiliated field should be understood that is; one of feature of the present utility model or object are: a kind of heating tube of the present utility model; by the transformation to U-shaped pipe; make the current stabilization of passing through in metal tube 3; protected resistance wire; extend the useful life of heating tube, reduced production cost.
It should be noted that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
