Technical field
This utility model belongs to heating tape technical field and in particular to a kind of petrochemical industry with automatic temperature-control electric heating belt is defeated
Send pipeline.
Background technology
That electric-heating belt has the advantages that to prevent is overheated, working service is easy and saves energy, be suitable for pipeline, equipment and
Container temperature control, heat tracing, insulation, heating, are widely used to oil, chemical industry, electric power, metallurgy, light industry, food at present, freeze, build
Build, coal gas, agricultural byproducts produce and other multiple industries.
When electric-heating belt is applied on petrochemical industry conveyance conduit, can play and prevent the solidification of petrochemical materials low temperature from leading
Cause the effect of line clogging.But the petrochemical industry conveyance conduit carrying electric-heating belt at present is all simply to wind electric-heating belt
Outside pipeline, when pipe diameter is based on needing to change, electric-heating belt heating effect not enough situation often occurs, difficult
To meet use requirement.
Utility model content
For above technical problem, this utility model provides a kind of structure optimization, can meet the band of various use requirements
The petrochemical industry conveyance conduit of automatic temperature-control electric heating belt.
This utility model is achieved through the following technical solutions：
A kind of petrochemical industry conveyance conduit with automatic temperature-control electric heating belt, the body including diameter change and orientation are wound around
In the electric-heating belt of body periphery, described electric-heating belt includes two conductive core and is covered in PTC core ribbon outside conductive core,
It is sequentially provided with flame retardant insulation, tincopper fuse wire braided armor and flame retardant sheath layer, described electric-heating belt is meeting outside PTC core ribbon
On the premise of adjacent spacing is not less than 5cm and no more than 20cm, its winding number of turns in body unit length is according to body
Diameter direct ratio change.
As preferred embodiment, described PTC core ribbon cross section is track type, the axle center of two conductive core respectively with its
The center of circle at two ends overlaps.
As preferred embodiment, flame retardant insulation equal with the thickness of flame retardant sheath layer and be tincopper fuse wire braided armor
Twice of thickness or more, the width of described PTC core ribbon is three times of flame retardant insulation thickness or more.
The beneficial effects of the utility model are：The electric-heating belt spacing that pipeline of the present utility model is wound around is defined in necessarily
In the range of, test proves that this spacing has good heating effect；In addition, electric-heating belt density is become according to the diameter of body
Change it is ensured that produced heat can be adjusted based on the size of body, thus meeting use requirement.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is electric-heating belt structural representation of the present utility model.
Label declaration：1- body, 2- electric-heating belt, 3- conductive core, 4-PTC core ribbon, 5- flame retardant insulation, 6- tinned copper wire
Braiding layer, 7- flame retardant sheath layer.
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and in conjunction with the embodiments.
With reference to Fig. 1, a kind of petrochemical industry conveyance conduit with automatic temperature-control electric heating belt of this utility model include body 1 and
Electric-heating belt 2.The diameter of body 1 can change, and electric-heating belt 2 orientation is wound in body 1 periphery.With reference to Fig. 2, electric-heating belt 2
Including two conductive core 3 and the PTC core ribbon 4 that is covered in conductive core 3 outside, outside PTC core ribbon 4, it is sequentially provided with flame retardant insulation
5th, tincopper fuse wire braided armor 6 and flame retardant sheath layer 7.
Spacing between adjacent electric-heating belt 2 is defined between 5cm to 20cm this utility model, and this kind of spacing is through experiment
Prove the distance values that can meet petrochemical pipe heating requirements, if spacing is too small, then the reliability between electric-heating belt 2
It is difficult to ensure that.On the premise of meeting above-mentioned restriction, winding circle in body 1 unit length for the electric-heating belt 2 of the present utility model
Several diameter direct ratio changes according to body 1, therefore, with the diameter change of body 1, the density of electric-heating belt 2 can be therewith
Change, in unit length, produced heat can adjust it is ensured that heat can meet use requirement according to body 1 diameter.
The quantity of conductive core 3 of the present utility model is two, and it is wound along cordage orientation by tinned copper wire, fiber
Rope can greatly increase the tensile strength of conductive core 3, and the mode that orientation is wound around may insure that tinned copper wire and cordage cooperation are tight
Close.
PTC core ribbon 4 cross section is track type, and its length and width ratio range is 4～5.The axle center of two conductive core 3 respectively with its
The center of circle at two ends overlaps.The edge at PTC core ribbon 4 two ends is equal from the centre distance of conductive core 3, integrally generates heat all during its work
Even, produced heat outwards transmit good to temperature consistency during belt body surface, therefore electric-heating belt 2 can realize better
Good heating properties.In order to reach better conductive effect, the diameter of conductive core 3 is preferably set to the one of PTC core ribbon 4 width
Half, in addition, the cross-sectional sizes of conductive core 3 are preferably 10 square millimeters to 20 square millimeters.
Flame retardant insulation 5, tincopper fuse wire braided armor 6 and flame retardant sheath layer 7 are sequentially arranged in outside PTC core ribbon 4, fire retardant insulating
Layer 5 and flame retardant sheath layer 7 can be realized using various current materials.Flame retardant insulation 5 equal with the thickness of flame retardant sheath layer 7 and
Twice for tincopper fuse wire braided armor 6 thickness or more, the width of PTC core ribbon 4 is that flame retardant sheath layer 7 is thick for flame retardant insulation 5
Three times of degree or more.Aforementioned proportion may insure tincopper fuse wire braided armor 6, flame retardant insulation 5 and flame retardant sheath layer 7, PTC core
With 4 in entirety shared by ratio increase successively, the structure of electric-heating belt 2 is compacter, and service behaviour is more preferable.
The foregoing is only preferred embodiment of the present utility model, be not limited to this utility model, for this
For the technical staff in field, this utility model can have various modifications and variations.All of the present utility model spirit and principle
