Abstract
A carbon fiber far infrared electro-thermal tube belongs to electrical heating elements, comprising a quartz cover and a long carbon fiber bundle. The utility model is characterized in that a quartz inner tube is arranged in the quartz tube; the heads of two hair-clamper electrodes are clamped a the two ends of the quartz inner tube; the long carbon fiber bundle is evenly wound on the quartz inner tube; the distance between the circles is increased at the two ends of the quartz inner tube, and then the two ends of the quartz inner tube is connected to the hair-clamper electrodes. The utility model is convenient to be made into carbon fiber far infrared electro-thermal tubes of different length, different power and different voltage, and gas phase aggradation effect can be reduced to prolong the service life of electro-thermal tube.
Description
Technical field
The utility model relates to a kind of electric heating device, particularly the carbon fiber far infrared electro-thermal tube.
Background technology
The electrothermal tube that the carbon fiber far infrared electro-thermal tube is made far above other materials owing to its far infrared transfer ratio is widely adopted.But existing carbon fiber far infrared electro-thermal tube has weak point.As carbon fiber is pressed solidly moulding, carbon carbon crystallizes into plates and packs into and be filled with the far infrared electro-thermal tube of making in the quartz ampoule of protective gas under the high temperature.Its complex process, the cost height, and, be difficult to satisfy needs for electrothermal tube different length, different capacity, different voltages because electric heating body needs compression molding.China ZL022482350 has proposed a kind of carbon fiber far infrared heating pipe, be that the carbon fiber exothermic part fasciculation is arranged in the quartz ampoule, tie up at the two ends of pencil carbon fiber exothermic part, links to each other with lead-out wire, is provided with the ring-type or the wiring shape supporter of supporting carbon fiber exothermic part in quartz ampoule.It is big that difficulty is not only implemented in this design concept, and to tie up lead-out wire at the carbon fiber working interface be irrational.Because carbon at high temperature changes the lead-out wire physical characteristic to the carbonization meeting of metal, the effect of vapour deposition is simultaneously constantly piled up the carbon volatile matter around lead-out wire, lead-out wire is become fragile, and it is big that contact resistance becomes, and influences the heat-generating pipe life-span.
Summary of the invention
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of and can slow down the vapour deposition effect, and the convenient carbon fiber far infrared electro-thermal tube of making different length, different capacity, different voltages on demand.
The utility model is realized in the following way: this carbon fiber far infrared electro-thermal tube comprises quartzy shell and carbon fiber filament bundle, the utility model is provided with quartz inner pipe in quartzy shell, two hair fastener shape electrode heads difference clamp is at the quartz inner pipe two ends, carbon fiber filament bundle uniform winding is on quartz inner pipe, and its two ends are strengthened turn-to-turn and are connected with hair fastener shape electrode after forming the cold-zone.Closed quartz tube shell two ends vacuumize the back and add protective gas according to a conventional method.
Described carbon fiber filament bundle can be made of two parts, and core is the straight endless tow of carbon fiber, and its periphery is carbon fiber filament bundle or the glass fiber bundle that spiral twines.Can strengthen the intensity of carbon fiber filament bundle like this.
Clamp place, described quartz inner pipe two ends is preferably in and opens two or more breach on the diagonal positions, in order to fixed carbon fiber filament bundle, does not allow its slip.
The utility model compared with prior art has following advantage:
1. be convenient to make on demand the carbon fiber far infrared electro-thermal tube of different length, different capacity, different voltages.By changing the carbon fiber filament wrapping just can reach the power of change electrothermal tube, voltage, length around the K number of the pitch of quartz inner pipe, the diameter that changes quartz inner pipe, change carbon fiber purpose.
2. can slow down the vapour deposition effect of carbon fiber far infrared electro-thermal tube, prolong electrothermal tube useful life.The temperature of carbon fiber vapour deposition is generally about 1000 ℃, the utility model strengthens the turn-to-turn distance of carbon fiber filament bundle coiling at the quartz inner pipe two ends, the power-intensive degree is reduced, form the cold-zone, thereby the temperature of hair fastener shape electrode junction is reduced to below 400 ℃, thereby can play the effect that slows down vapour deposition, carbonization also reduces simultaneously.
