Description

Glass tube heater

1, technical field

The utility model relates to a kind of electrical heating elements, specifically a kind of Glass tube heater.

2, technical background

As everyone knows, the electric heating element of prior art mostly uses nichrome, molybdenum filament, tungsten filament material to do electric heating element.Owing to the reason of these electric heating element materials self inherent characteristic in use has a lot of deficiencies, the electric heating element of making as general nichrome material, molybdenum filament, tungsten filament material, easily oxidation of surface in the electric heating use causes local overheating thus and is blown, and useful life is short.Have visible light to exist simultaneously in the electric heating process, so the heat efficiency is low.Though above-mentioned thermo electric material has the field of the application of broad, but they are difficult to be made into the electric heating element that uses anti-permanent and heat efficiency height and do not influence its range of application.

3, summary of the invention

The purpose of this utility model is at above weak point, and a kind of simple in structure, long service life, electric conversion efficiency height, operating temperature range is wide, the course of work does not have visible light Glass tube heater are provided.

The technical scheme that its technical problem that solves the utility model adopts is: adopt carbon fiber bundle, carbon fiber preform to replace common nichrome, molybdenum filament, tungsten filament material to make heater, interior insulation fixed mount is arranged in the insulation shell, carbon fiber electrothermal part is coated on the interior insulation fixed mount, its two ends are connected helical casing and connect with interior electrode, insulating case is equipped with at the two ends of insulation shell, the end that external electrode connecting line, brace and interior electrode are connected helical casing joins and is enclosed in the insulating case, and carbon fiber electrothermal part is with the external insulation fixed mount outward; Have bleeding point on the insulation shell, the transition insulating barrier can be set in the inner chamber of insulation shell in addition also the transition insulating barrier can be set.

Glass tube heater of the present utility model is compared with prior art, has reasonable in design, and processing technology is simple, and is easy to use, the life-span is long, heat efficiency height, and characteristics such as serviceability temperature wide ranges and applied range, thereby, have good value for applications.

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 Glass tube heater;

Accompanying drawing 2 is the enlarged diagram at Figure 1A place.

5, embodiment

Explain below with reference to Figure of description Glass tube heater of the present utility model being done.

Glass tube heater of the present utility model, its structure is by external electrode connecting line 1, insulating case 2, brace 3, interior electrode connects helical casing 4, insulation shell 6, interior insulation fixed mount 7, carbon fiber electrothermal part 8 and external insulation fixed mount 9 constitute, interior insulation fixed mount 7 is arranged in the insulation shell 6, carbon fiber electrothermal part 8 is coated on the interior insulation fixed mount 7, its two ends are connected helical casing 4 and connect with interior electrode, insulating case 2 is equipped with at the two ends of insulation shell 6, external electrode connecting line 1, brace 3 is connected helical casing 4 with interior electrode end joins and is enclosed in the insulating case 2, the carbon fiber electrothermal part 8 outer external insulation fixed mounts 9 that are with; Have bleeding point 5 on the insulation shell 6; Transition insulating barrier 10 can be set in the inner chamber of insulation shell 6 also transition insulating barrier 10 can be set.

Its processing and fabricating of Glass tube heater of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.The processing and fabricating of carbon fiber is a known technology, and electric heating element can use polypropylene hydrogen base or asphalt base carbon fiber to make; The transition insulating barrier is to be made by inorganic insulating material, quartzy class glass insulating material and inert gas, and insulation shell is to be made by exotic materials such as inorganic insulating material and quartzy class glass insulating materials; External insulation fixed mount and interior insulation fixed mount are made with quartz or ceramic material; The transition brace is made by metal material.

The advantage of the carbon fibre compound heating element that this use is novel is:

1, structural design is simple;

2, thermo-lag is little, quick heating, and heating temp is even;

3, surface temperature is at 200 ℃-900 ℃; Surface heat power is at 5W/cm²-40W/cm ²It Between, the technical parameter range of variation is wide;

4, the geometry range of variation is wide, therefore in actual application, can adopt standard or non-standard unit mode to use;

5, electric property is stable, reliable, and useful life is up to more than 10000 hours.

6, applied environment: can be in water, use in the air.Industry can be applied in widely, agricultural, air heat of civil area or the like.

Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
