Abstract
The utility model relates to an industry electric tracing technical field is an even electric heat tracing pipe of thermal field. Including the conveyer pipe, be provided with 3 strip metal braid over braids along axial direction on the surface of conveyer pipe, the braid over braid is connected with three phase current's electrode respectively, be provided with a plurality of electro -heat equipment between the braid over braid, braid over braid and electrothermal welding parcel have the first insulation layer. Be provided with the second insulating layer between conveyer pipe and the braid over braid. Braid over braid equidistance interval sets up. Electro -heat equipment evenly arranges on the surface of conveyer pipe. The utility model discloses as long as even connect with the mains just passablely, consequently the installation is more convenient, in addition, sends out an electro -heat equipment and arranges evenly on the body that being heated of body is more even, can not lead to the fact the too high phenomenon of the local temperature, and is not only energy -conserving, can lengthen the life of product in addition during the use, and in addition, because adoption three phase power supply, the electric current is less, and the loss of voltage is not notable, can make longer heat tracing pipe.
Description
Technical field
This utility model relates to industrial electro heat tracing technical field, is a kind of uniform electric tracing tube of thermal field.
Background technology
Electric tracing tube in the market, is that additional electric tracing cable composition, the sampling tube of such as flue gas are managed in conveying mostly
The heat tracings of line etc. are all to adopt in this way, but this way has many shortcomings, mainly has:
1, installation difficulty, the heat tracing of the sampling pipeline of some flue gases, sampling tube is the most relatively fine, but electric tracing cable is
The specification of standard, installs on tiny pipe and just seems relatively difficult.
2, heat tracing thermal field is uneven, and traditional heat tracing mode is that accompanying-heat cable is bundled on conveying pipe or sampling tube, the way of contact
Being wire-shaped contact, the thermal field of heat tracing is uneven.
3, uneven due to heat tracing, want the energy of accompanying-heat cable to be delivered to carry on pipe, hence it is evident that the temperature ratio of cable can be felt
Higher, particularly it is especially apparent in the application scenario that the media such as flue gas sampling are high-temperature gases.
4, heat tracing is frequently with two core cable, and if same heat tracing power, heart yearn electric current is big, and voltage drop is big, and single-point power supply is powered
Apart from short etc..
Utility model content
The technical problems to be solved in the utility model is to provide a kind of uniform electric tracing tube of thermal field, has easy to install and use, companion
Heat uniformly, service life length feature.
In order to solve above-mentioned technical problem, this utility model includes conveying pipe, and the outer surface of described conveying pipe in axial direction sets
Being equipped with 3 metallic braids, described braid over braid is connected with the electrode of three phase mains respectively, is provided with some between described braid over braid
Electric heating device, described braid over braid and electric heating melting are enclosed with the first insulating barrier.
It is provided with the second insulating barrier between described conveying pipe and braid over braid.
Described braid over braid equi-spaced apart is arranged.
Described electric heating device is evenly arranged on the outer surface of conveying pipe.
Electric tracing tube described in the utility model is installed more convenient, and the ratio that is heated of body is more uniform, does not results in local temperature too high
Phenomenon, and longer heat tracing pipe can be manufactured.
Accompanying drawing explanation
Fig. 1 is sectional drawing of the present utility model；
Fig. 2 is the layout drawing of electric heating device
Detailed description of the invention
Embodiment cited by this utility model, is only intended to help and understands this utility model, should not be construed as this utility model
The restriction of protection domain, for those skilled in the art, on the premise of without departing from this utility model thought,
Can also make improvements and modifications this utility model, these improve and modify the model also falling into the protection of this utility model claim
In enclosing.
As depicted in figs. 1 and 2, this utility model includes carrying pipe 1, and described conveying pipe 1 can be tube for transfusion or appendix.
If described conveying pipe 1 is made up of insulant, then conveying pipe 1 outer surface on be in axial direction provided directly with 3 by
The braid over braid 2 of copper wire establishment, if conveying pipe 1 has metal material to make, then first arranges the second insulation at the outer surface carrying pipe
Layer 5, this insulating barrier 5 can be fluoro-containing plastic layer, is more in axial direction laid in by metallic braid 2 on second insulating barrier 5.
Described braid over braid 2 is connected with the electrode of three phase mains respectively, is welded with some electric heating devices 3, electric heating between described braid over braid 2
Quantity and the power of device determine according to heating requirements.This electric heating device 3 can be heating wire or electric heating block etc., is evenly arranged in
On the outer surface of conveying pipe 1, described braid over braid 2 and electric heating device 3 are enclosed with the first insulating barrier 4 being made up of fluoro-containing plastic,
Thus at the outer surface formation layer protective layer of braid over braid 2 and electric heating device 3.
This utility model, by electric heating device and conveying pipe overall processing, as long as it is the most permissible to connect power source in use, is therefore installed
More convenient, it addition, generating thermal is to be evenly arranged on body, the ratio that is heated of body is more uniform, does not results in local temperature
Spend high phenomenon, the most energy-conservation, and the service life of product can be extended, further, since use three phase supply, electric current
Less, voltage reduces inconspicuous, can manufacture longer heat tracing pipe.
