Description
Technical field
This utility model relates to heat-treatment furnace electric-heating technology field, particularly relates to a kind of energy-saving efficient electricity spoke
Penetrate pipe.
Background technology
It is known that along with the development of modern science and technology, people are to the energy-conservation, efficient of heat-treatment furnace and use
The requirement in life-span is more and more higher.The radial canal of traditional electrothermal radiation tube is a resistant to elevated temperatures stainless steel tube,
Pipe is built with being inserted in many group insulators the heating unit assembly formed, the heat after its energising by many resistance wires
Amount first passes through radial canal to outside radiations heat energy, and one is the heat energy consuming heat generating component；Two is heat collection
In inside radial canal, affect the service life of whole radial canal.
Utility model content
For solving above-mentioned technical problem, this utility model purpose is to provide a kind of energy-saving efficient electric radiant tube.
To achieve these goals, this utility model provides a kind of energy-saving efficient electric radiant tube, including spoke
Beam assembly, heater, the first insulating part, the second insulating part and electrode lead-out rod, described radiant body assembly
Including some radial canals and connector, being connected by some described connectors between described radial canal, formation is engraved
Vacant duct, the two ends of described hollow out pipeline are separately fixed on described first insulating part and the second insulating part, institute
State in heater is arranged on described hollow out pipeline and one end of described heater and through described first insulating part
Two electrode lead-out rods are connected.
Further, described connector is set to rustless steel lath, and the width of described rustless steel lath is
30～40mm.
Further, described radial canal is set to stainless steel tube, and the thickness of described stainless steel tube is 3～5mm.
Concrete, a length of the 30 of described stainless steel tube～50mm.
Further, described heater includes heating element heater and protection pipe, and described heating element heater is arranged on described
In protection pipe.
Concrete, described heating element heater is set to nickel filament or Fe-Cr-Al wire.
By such scheme, this utility model at least have the advantage that energy-saving efficient electric radiant tube except
Ensure that outside thermal-radiating intensity, moreover it is possible to reach more energy efficient, heat distribute more fully and service life more
Long purpose.
Described above is only the general introduction of technical solutions of the utility model, in order to it is new to better understand this practicality
The technological means of type, and can be practiced according to the content of description, below with preferable reality of the present utility model
After executing example and coordinating accompanying drawing to describe in detail such as.
Accompanying drawing explanation
Fig. 1 shows the cut-away view of a kind of energy-saving efficient electric radiant tube of the present utility model；
Fig. 2 shows the A-A` sectional view of a kind of energy-saving efficient electric radiant tube in Fig. 1.
Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.
Following example are used for illustrating this utility model, but are not limited to scope of the present utility model.
See Fig. 1 and Fig. 2, including radiant body assembly, heater the 1, first insulating part the 2, second insulating part
3 and electrode lead-out rod 4, radiant body assembly includes some radial canals 5 and connector 6, logical between radial canal 5
Crossing some connectors 6 to be connected, form hollow out pipeline, the two ends of hollow out pipeline are separately fixed at the first insulating part 2
With on the second insulating part 3, heater 1 be arranged in hollow out pipeline and heater 1 one end with through first
Two electrode lead-out rods 4 of insulating part 2 are connected.
A kind of energy-saving efficient electric radiant tube operation principle that this utility model provides is as follows:
Energy-saving efficient electric radiant tube improves this trocar sheath of overall electric radiant tube in conventional electric radiant tube,
But the short radial canal pipeloop cut by radial canal according to the Design of length three to five of radial canal, then
Coupled together by 6 radial canal pipeloops of several connectors, the radial canal trocar sheath pipe of one hollow out of composition
Road, its internal heater 1 is constant, heater 1 is put in the pipeline of radial canal trocar sheath of hollow out,
Heater 1 is connected with extraneous power supply by two electrode lead-out rods 4, logical during heater 1 heating
The pipeline crossing hollow out externally carries out radiations heat energy, heat will not be made to concentrate on inside radial canal, affect heater 1
Service life, and the radiation efficiency of radial canal can also be improved.
In order to ensure the intensity of hollow out pipeline in electric radiant tube, connector is set to rustless steel lath, rustless steel
The width of lath is 30～40mm.
In order to preferably play the radiation efficiency of electric radiation, radial canal is set to stainless steel tube, stainless steel tube
Thickness is 3～5mm, a length of the 30 of stainless steel tube～50mm.
In order to protect heater, heater includes heating element heater and protection pipe, and heating element heater is arranged on
In protection pipe, heating element heater is set to nickel filament or Fe-Cr-Al wire, preferably plays insulation effect to play
Really, the first insulator and the second insulator are disposed as high temperature resistant nonmetallic materials.
Below it is only preferred implementation of the present utility model, is not limited to this utility model, it should refer to
Go out, for those skilled in the art, before without departing from this utility model know-why
Putting, it is also possible to make some improvement and modification, these improve and modification also should be regarded as guarantor of the present utility model
Protect scope.
