The advantages of the quartz electric heating tube are obvious. Because the sliver belt-shaped or circle electric heating body woven by filament carbon fiber and metal wires or nonmetal wires is taken, the quartz electric heating tube is flexible and is acid-alkali resistant. The usage temperature is 200-800 DEG C; the power is 10-40W/cm< 2 >; the electric appliance performance is stable and reliable; the service life is higher than 10000 hours. The utility model can be widely applied in liquid, water and air in industry, foods, pharmacy processing and instrument fields. Compared with the prior art, the quartz electric heating tube has strong random usability, random geometry change, reasonable structure, simple technology and wide usage range. The thermal efficiency reaches more than 98%. The utility model has the outstanding advantage that the filament carbon fiber section tube realizes the characteristics of high thermal efficiency, rapid startup, long service life and wide temperature range, and has wide application value.
Description
Technical field
The utility model belongs to the electric equipment accessory, particularly be in the electric equipment heating usefulness the important devices quartz electrothermal tube.
Background technology
As everyone knows, the quartz electrothermal tube of prior art, the general metallic heating body that adopts, as: nichrome, molybdenum filament, tungsten filaments etc., nonmetal heating unit have filament fiber and short silk gum grain tapetum fibrosum, and electric heating element is in the electric heating use, easily cause surface oxidation to be blown, simultaneously electricity is converted into the efficient of light, and metal material is than nonmetallic materials height, so, carbon purity is high more in the carbon fibre, and the heat efficiency of electricity conversion is just high more, and relatively all be no more than 5000 hours the useful life of its two classes exothermic material, and the difficult realization of the special-shaped calandria that exists use under the particular surroundings, the power less stable, useful life is short, the weak point that start-up time is long.
Summary of the invention
The purpose of this utility model is for a kind of long service life, the electric conversion efficiency height, and working temperature realizes wide ranges, the Far-infrared Heating effect is obvious, and external shape can adapt to special-shaped various quartz electrothermal tube that technological requirement changes.
The purpose of this utility model is realized by following mode, specifies as follows:
Present advanced quartz electrothermal tube, housing is a quartz glass tube, in establish the refractory metal heating wire; Vacuumize or be filled with inert gas in the housing; Electrode is high temperature resistant heating wire, and its shortcoming mainly is that the life-span is short, is difficult for making various obform bodies; Electric heating element of the present utility model is bar-shape or the circular electric heating element that is formed by long filament carbon fiber and wire or nonmetal wire braiding.
Advantage of the present utility model clearly because what adopt is that the long filament carbon fiber weaves bar-shape or the circular electric heating element that forms with wire or nonmetal wire, so be flexible, can be made shaped bodies such as U, S, annular; Structural design is simple; Quick heating, the even acid and alkali-resistance of heater temperature, serviceability temperature is at 200-800 ℃, and power is at 10-40W/cm
2, electric property is stable, and is reliable, exceeds 10000 hours useful life, can be widely used in industry, food, system; In the water of medicine processing, instrument field, use in the air; In a word, in sum, the utility model carbon fiber quartz electrothermal tube is compared with prior art, usability is strong at random, and the heat efficiency is up to more than 98%, and random geometry changes, rational in infrastructure, technology is simple, and the scope of application is wide, and outstanding advantage is that long filament carbon fiber shape tube has been realized heat efficiency height, start rapidly, long service life, the characteristics of the wide economize on electricity 30% of temperature range are with a wide range of applications.
Description of drawings

Fig. 2 is the utility model embodiment schematic diagram
Among the figure: the 1st, lead, the 2nd, connecting filament, the 3rd, brace, the 4th, connecting filament, the 5th, support, 6 electric heating elements, the 7th, housing, the 8th, pore, the 9th, fixed mount, the 10th, electrode, the 11st, fixed body, the 12nd, fixture.
Embodiment
Above-mentioned " special-shaped electric heating elements such as bar-shape that braiding forms or circle " are meant that the braiding of long filament carbon fiber and long filament carbon fiber wire forms; Be meant that the braiding of long filament carbon fiber and metal filament filament forms; Can be meant that also the braiding of long filament carbon fiber and nonmetal filament fiber silk forms; Also can be bar-shape or the circular electric heating element that long filament carbon fiber, wire, nonmetal wire three mixed weaving form.
As seen from Figure 1: power lead 1 is an external wire; Connecting filament 2 is that quartz electrothermal tube exposes the high temperature resistant wire that is connected with external power; Connect 2, brace 3, connecting filament 4 all are electric heating elements 6 with outer conductor between the high temperature resistant transitional lead that is connected, all good with being welded as, all make of the conductor molybdenum; Consistent book electrode 10 with the electric heating element shape, fixed body 11, fixture 12 are formed the electrode nipple device, electric heating element 6 evenly all is trapped among electrode 10 outsides of propping up by insulation fixed body 11, tighten up by fixture 12 compression sets again, each part is made of molybdenum filament, molybdenum sheet, reaches the best electrical coupling state of full contact; Make the crucial matter pipe perfection of this easy burn-out.
Support 5 is elements of housing 7 internal fixation electric heating elements 6, generally uses ceramics bracket; Electric heating element 6 is key elements of quartz electrothermal tube, usefulness be bar-shape or the circular electric heating element that long filament carbon fiber and wire or nonmetal wire braiding form, so be flexible, can make shaped bodies such as U, S, annular; Housing 7 is shells of quartz electrothermal tube, generally is quartz glass tube, can protect electric heating element 6, can charge into inert gas again in shell; Pore 8 is fabrication holes, vacuumize after completing or inert gas injecting after just shut; Fixed mount 9 is fixed on the adjacent wall of obform body glass tube bendings such as U-shaped.
Fig. 2 is the annular embodiment schematic diagram of quartz electrothermal tube, and is same, because electric heating element is a flexible body, so, can make different shape and big or small quartz glass tube as required.
The utility model colleague technical staff can implement.
