Description
Technical field
The utility model relates to a kind of novel carbon fiber infrared ray electric thermal element, specifically a kind of novel carbon fiber quartz electrothermal tube.
Background technology
Carbon fiber infrared ray quartz electrothermal tube is in the hope of the electric conversion efficiency height, and environmental protection and energy saving are pollution-free to wait good characteristic, waits until extensive use at civilian and industrial circle.The characteristics of carbon fiber electric heating tube be exactly with carbon fiber filament as heater, be the electrothermal tube of insulation crust with the quartz glass tube, the caliber of normally used quartz glass tube is φ 10, φ 12, φ 14, φ 16, φ 18mm etc.Because carbon fiber wire is nonmetallic materials, the material softness is fixed (general supporter is φ 5, and φ 6, and φ 7, φ 8 quartz glass tubes such as grade) on the supporter of tubulose by carbon fiber is fastened.What also have ropes the twisting of carbon fiber filament heater through the technology typing.Have for further strengthening the carbon filament of twisting typing, again the carbon fiber wire heater is provided with reinforcements such as metal tungsten wire or molybdenum filament outward, metal reinforcing be wrapped in uniformly the carbon fiber filament heater around, to strengthen the intensity of carbon fiber wire hollow spiral.
All there are a lot of drawbacks in above manufacture craft, and the technology relative complex, and drawback is as follows:
1. be wrapped in caliber φ 5 after carbon fiber filament being twisted into rope, φ 6, and φ 7, and on the inner supporting body of quartz glass tubes such as φ 8mm, there is following drawback in carbon fiber filament bundle two ends with spiral molybdenum filament electrode casing pressure or with the manufacture method that molybdenum filament is tied up:
Make the electrothermal tube heating slow 1.1 its supporter absorbs heat, cause toggle speed slow;
1.2 carbon fiber filament is wrapped in the quartz glass supporter, the volatilization of quartz glass tube supporter silica flour can spread on the inwall of quartz ampoule tube chamber under the long term high temperature, influences attractive in appearance; Because of constantly filling the air of silica flour, cause the heat radiation of carbon fiber filament heater bad, thereby influence the life-span, even cause the interior impurity component of airtight quartzy tube chamber constantly to increase, foreign gas expands, and causes electrothermal tube explosion etc.
1.3 tie up owing to adopt molybdenum filament screw electrode casing pressure and molybdenum filament, at casing pressure with tie up the coup injury that process all can cause the carbon fiber filament heater, and because the internal orifice dimension of screw electrode size and quartz glass supporter external diameter size all have error, and the carbon fiber filament softness, can cause casing pressure not tight, firmly, cause spark phenomenon, from influencing the life-span, even because of electrode is connected insecurely with carbon fiber filament heater junction, the energy that momentary arcing produces causes phenomenon such as electrothermal tube explosion to take place.
2. rope is twisted in the carbon fiber filament heating, and because of the dynamics size bad grasp of carbon filament in twisting process twisting, photochromic non-uniform phenomenon can appear in the hollow coiled carbon fibers long filament heater of the carbon fiber filament heater of twisting behind technological forming.Because in the twisting process, the twisting dynamics is crossed conference and caused the carbon filament fracture of wire more, influences the attractive in appearance of carbon filament, and because of the big tension of twisting power, also can cause the elongated or phenomenon such as shorten of hollow coiled carbon fibers long filament heater size behind technological forming.
3. for reducing the variation of the hollow coiled carbon fibers long filament heater size of twisting back carbon fiber filament behind technological forming, what have is just twining metal reinforcing on the carbon fiber filament heater, but because the ratio of the expansion of metallic heating body and nonmetal carbon fiber exothermic part and shrinkage is different, also can have influence on the life-span of carbon fiber exothermic part, and this production method complex process.
4. the single bag pressure formula molybdenum sheet electrode or the stainless steel electrode that mostly adopt of the electrode connecting parts of hollow screw carbon fibre long filament heater, because the big very thin thickness of molybdenum matter electrode hardness, when crimping carbon fiber filament heater, if it is bad that the crimping dynamics is handled, can cause damage to the carbon fiber filament heater; Because the molybdenum sheet electrode is very thin, the fragility of molybdenum matter electrode in addition, when the mechanically use that vibrations are arranged, the afterbody of the molybdenum sheet electrode of press seal inside the quartz glass ruptures easily.And the very big electric current of the welding of molybdenum and molybdenum needs, firm welding degree instability, therefore carbon fiber electrode occurring through regular meeting draws molybdenum rod and molybdenum sheet electrode pads obscission.
5. at present a lot of practices is filled with a spot of inert gas with exactlying in airtight quartz glass tube tube chamber, since reduce the oxidation of carbon fiber filament heater, and the small amount of impurities gas compression that of burning of carbon fiber filament heater long filament time is arrived between the electrode cold-zone.But the carbon fiber filament heater is in long-time combustion process, can produce certain foreign gas really, and along with long use foreign gas can constantly increase, if these a spot of foreign gases are not removed, to accumulate over a long period and can cause the oxidation of carbon fiber filament heater, vacuum degree sharply descends, because the continuous accumulation of foreign gas, the inert gas that had before charged in the airtight in addition quartz glass tube can cause breaking of quartz electrothermal tube, even phenomenon such as explosion.
