Abstract

The utility model provides a solid filament carbon fiber electrothermal tube, belonging to the electric heating element. The structure comprises a connection electrode, an insulation layer, a carbon fiber heating layer and a carbon fiber heating layer supporting skeleton. The carbon fiber heating layer is arranged on the outer layer of the carbon fiber heating layer supporting skeleton. A clamping element is tight fixed out the carbon fiber heating layer of the both ends of the carbon fiber heating layer supporting skeleton. The connection electrode of inner part of the carbon fiber heating layer is clamped and fixed in the inner cavities on both ends of the carbon fiber heating layer supporting skeleton. The insulation layers are arranged on the carbon fiber heating layer and the outer layer of the clamping element. Compared with the prior art, the solid filament carbon fiber electrothermal tube of the utility model has the characteristics of simple structure, long service life, high conversion efficiency of the electricity and the heat, broad operating temperature range, etc. and does not have the visible light in the operating process.

Description

Entity long filament carbon fiber electric heating tube
1, technical field
The utility model relates to a kind of electrical heating elements, a kind of specifically entity long filament carbon fiber electric heating tube.
2, background technology
As everyone knows, the thermo electric material under the prior art mostly uses nichrome, molybdenum filament, copper wire, tungsten filament or ptc material to do electric heating element.Reason owing to these thermo electric materials self inherent characteristic, in use exist many deficiencies, as the electric heating element that general nichrome material, molybdenum filament, copper wire, tungsten filament material are made, easily oxidation of surface in the electric heating process, cause local overheating thus and be blown, useful life is short.Have visible light to exist in the process of electric heating simultaneously, so the heat efficiency is low; Easily decay and puncture of electrical heating power during ptc material uses, useful life is short, and the heat efficiency is low.Though above-mentioned thermo electric material has the application of broad, they but are difficult to be made into the anti-permanent and high electric heating element that does not influence its range of application again of the heat efficiency of use.
3, summary of the invention
Technical assignment of the present utility model is at above weak point, provides that a kind of simple in structure, long service life, electric conversion efficiency height, operating temperature range are wide, the entity long filament carbon fiber electric heating tube of no visible light in the course of work.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of entity long filament carbon fiber electric heating tube, comprise connection electrode, insulating barrier, carbon fiber heating layer and carbon fiber heating layer support frame, carbon fiber heating layer support frame skin is provided with the carbon fiber heating layer, the carbon fiber heating layer at carbon fiber heating layer support frame two ends is fastened with clamping element outward, and the connection electrode that it is inner fixes in the two ends inner chamber of carbon fiber heating layer support frame, and carbon fiber heating layer and clamping element skin are provided with insulating barrier.
Entity long filament carbon fiber electric heating tube of the present utility model is compared with prior art, have that simple in structure, long service life, electric conversion efficiency height, operating temperature range are wide, characteristics such as no visible light in the course of work, except that above characteristics, the utility model also comprises:
1, structural design is simple;
2, thermo-lag is little, quick heating, and heating temp is even;
3, electric property is stable, and reliable, useful life is up to more than 10 years;
4, applied environment: can be applied in the air of industry, agricultural, civil area and liquid heat or the like widely.
Thereby, the utlity model has excellent popularization use value.
4, description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the structural representation of entity long filament carbon fiber electric heating tube.
5, embodiment
Explain below with reference to Figure of description entity long filament carbon fiber electric heating tube of the present utility model being done.
A kind of entity long filament carbon fiber electric heating tube, comprise connection electrode 1, insulating barrier 2, carbon fiber heating layer 4 and carbon fiber heating layer support frame 5, carbon fiber heating layer support frame 5 skins are provided with carbon fiber heating layer 4, the carbon fiber heating layer 4 outer clamping element 3 that is fastened with at carbon fiber heating layer support frame 5 two ends, and connection electrode that it is inner 1 fixes in the two ends inner chamber of carbon fiber heating layer support frame 5, and carbon fiber heating layer 4 and clamping element 3 skins are provided with insulating barrier 2.
When making the utility model, connection electrode 1 is inserted at the two ends of the carbon fiber heating layer support frame of making at insulating material 5, twine the carbon fiber heating layer 4 that adopts carbon fiber bundle or carbon fiber preform to make at its skin then, with the clamping element 3 of conductive metallic material the carbon fiber heating layer 4 at carbon fiber heating layer support frame 5 two ends is fixed on the skin of connection electrode 1 again, simultaneously connection electrode 1 is fixed on inside, carbon fiber heating layer support frame 5 two ends, at carbon fiber heating layer 4 and clamping element 3 skins insulating barrier 2 is set at last.
During use, at 1 liang of termination electricity of connection electrode, electric current directly forms the loop by carbon fiber heating layer 4 to other end connection electrode 1 through connection electrode 1, finishes energising heating function of the present utility model.
Entity long filament carbon fiber electric heating tube of the present utility model, its connection electrode 1 and clamping element 3 adopt the metallic conduction material; Insulating barrier 2 and carbon fiber heating layer support frame 5 adopt nonmetallic materials such as quartz, pottery; Carbon fiber heating layer 4 adopts carbon fiber bundle or carbon fiber preform to be entwined.
Entity long filament carbon fiber electric heating tube of the present utility model, its processing and fabricating is very simple, gets final product processing and fabricating shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
