The internal cavity of the screw-shaped silica glass pipe is provided with the carbon fiber heating body; both ends of the carbon fiber heating body are respectively fixed on the external side of the electrode fixing ceramic part; the outside of the carbon fiber heating body is in turn coated with the sheet internal electrode and the spring electrode; the spring electrode is connected to the outer electrode via the electrode connection lug arranged inside the silica glass pipe; the direction of the outer electrode is parallel to the rotary direction of the screw silica glass pipe. Compared with prior art, the carbon fiber screw heater has the advantages of simple structure, long service life, high electric heating conversion rate without visible light in heating process.
Description
1, technical field
The utility model relates to a kind of electrical heating elements, specifically carbon fiber spiral heating device.
2, background technology
As everyone knows, the heating element under the prior art mostly uses nichrome, molybdenum filament, 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, 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
The purpose of this utility model is at above weak point, and a kind of simple in structure, long service life, carbon fiber spiral heating device that electric conversion efficiency is high are provided.
The technical scheme that its technical problem that solves the utility model adopts is: carbon fiber spiral heating device, comprise external electrode, electrode connecting piece, spring electrode, electrode in the sheet, electrode is porcelain spare fixedly, carbon fiber exothermic part, quartz glass tube is formed, be provided with carbon fiber exothermic part in the spiral quartz glass tube cavity, the carbon fiber exothermic part two ends are separately fixed at the fixedly porcelain spare outside of electrode, external interior electrode of sheet and the spring electrode of coating successively of carbon fiber heating, spring electrode links to each other with external electrode by the electrode connecting piece in the quartz glass tube, and the direction of external electrode is parallel to the hand of spiral of spiral quartz glass tube.
Fill in the quartz glass tube and be provided with inert protective gas.
Bleeding point is arranged on the quartz glass tube.
Carbon fiber spiral heating device of the present utility model is compared with prior art, has characteristics such as no visible light in simple in structure, long service life, electric conversion efficiency height, the heating process, and except that above characteristics, the utility model also comprises:
(1), thermo-lag is little, quick heating, heating temp is even;
(2), electrical heating power is adjustable, the surface Working Temperature wide ranges;
(3), electric property is stable, reliable, useful life is up to more than 5 years;
(4), can be applied in the liquid of industry, agricultural, civil area and air heat or the like widely.
Thereby, the utlity model has excellent popularization use value.
4, description of drawings
Accompanying drawing 1 is the structural representation of carbon fiber spiral heating device;
Accompanying drawing 2 is a carbon fiber spiral heating general ability portion enlarged drawing.
5, embodiment
Explain with reference to Figure of description 1 with below 2 pairs of carbon fiber spiral heating devices works of the present utility model of accompanying drawing.
Carbon fiber spiral heating device of the present utility model, comprise external electrode 1, electrode connecting piece 2, spring electrode 3, electrode 4 in the sheet, electrode is porcelain spare 6 fixedly, carbon fiber exothermic part 7, quartz glass tube 8 is formed, be provided with carbon fiber exothermic part 7 in spiral quartz glass tube 8 inner chambers, carbon fiber exothermic part 7 two ends are separately fixed at fixedly porcelain spare 6 outsides of electrode, carbon fiber exothermic part 7 outer interior electrode 4 of sheet and the spring electrodes 3 of coating successively, spring electrode 3 links to each other with external electrode 1 by the electrode connecting piece 2 in the quartz glass tube 8, and the direction of external electrode 1 is parallel to the hand of spiral of spiral quartz glass tube 8.
Fill in the quartz glass tube 8 and be provided with inert protective gas 5.
During use, the external electrode 1 at carbon fiber spiral heating device two ends is inserted two poles respectively, electric current from an end external electrode 1 in electrode connecting piece 2, spring electrode 3 and sheet electrode 4 to carbon fiber heating body 7, get back to power supply from carbon fiber heating body 7 other ends electrode 4, spring electrode 3, electrode connecting piece 2 and external electrode 1 in sheet then, thereby constitute electric power loop; Carbon fiber heating body 7 heatings when electric current is flowed through carbon fiber heating body 7, the tube wall that heat is passed to quartz glass tube 8 by radiation and convection current dispels the heat.
Carbon fiber spiral heating device of the present utility model, carbon fiber exothermic part can adopt braid, and for example braid over braid, rope are made; Electrode and electrode connecting piece adopt metal material to make in external electrode, spring electrode, the sheet, and its processing and fabricating is very simple and convenient, 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.
