Abstract
This electro-thermal tube for liquid contains quartz far infrared tube, ring-flange and sealed cover. The quartz-infrared tube is plugged in the ring-flange and connected together, in the flange there are two seal layers, inner layer is sealed by heat-resisting materials outer layer is sealed by rigid structure material out of the quartz-far-infrared-ray tube covered by shelter net.
Description
Technical field
The present invention relates to the electrothermal tube that a kind of heating liquid is used.
Background technology
The most tubular metal electric heating elements that adopt of the electrothermal tube that present heating liquid is used.This electrothermal tube is generally made shell with stainless steel tube, and heating alloy places in the middle of the metal tube, fill insulant magnesia powder then, and sealing is made.If sealing is good inadequately or excess temperature, overload, can cause that all the magnesia powder moisture absorption is rotten, make electrothermal tube decreasing insulating even destruction, cause potential safety hazard.In addition, the metal tube thermal inertia is big, and startup is slow, efficient is low, corrosion-resistant, fouling easily again.Chinese patent 01262675 has proposed at tubular metal electric heating element surface coated one deck fluorocarbon polymer antiscale and corrosion resistance to be improved.But this technical measures are still failed to solve because of the moisture absorption or excess temperature, overload and are made electrothermal tube decreasing insulating and the low problem of the heat efficiency.
Summary of the invention
The purpose of this invention is to provide a kind of good insulation preformance, start fast, high, corrosion-resistant, the less scaling liquid electrothermal tube of the heat efficiency.
The present invention adopts following technical scheme to realize: this liquid is made of quartzy far-infrared tube, flange and sealant with electrothermal tube, quartzy far-infrared tube inserts flange and fixes, double-layer seal is set in the flange, inner sealant layer is a high-temperature flexible binding material sealant, outer sealing layers is a rigidity binding material sealant, and quartzy far-infrared tube is provided with protection network outward.
The present invention has following advantage compared to existing technology:
1. high insulating property.The present invention adopts quartzy far-infrared tube as heater element, at the high pressure resistant 3600V that reaches of the condition of high temperature, insulation resistance 〉=500M Ω.
2. the resisting temperature cataclysm is good.This electrothermal tube is not quick-fried under 1000～5 ℃ of temperature jump conditions not to be split, even with the heating of electrothermal tube overload, adding cold water then can explosion yet.
3. start fast.Can reach rated power and temperature in about three seconds.
4. far infrared radiation heating, heat distribution is even, heat efficiency height.
5. corrosion-resistant, and less scaling.Quartz ampoule can antiacid alkali and residual chlorine ion etching.
6. quartzy far-infrared tube is connected the employing flexibility with flange and two kinds of materials double-layers sealings of rigidity are bonding, the flexible shock resistance that strengthens, and rigidity makes the sealing intensity raising.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Referring to accompanying drawing, this liquid is made of quartzy far-infrared tube 5, flange 2, inner sealant layer 3, outer sealing layers 4 with electrothermal tube.The quartzy far-infrared tube 5 vertical flanges 2 that insert are fixed, and in the flange 2 double-layer seal are set, and outer sealing layers 3 adopts the rigidity binding materials to be sealing adhesive materials such as for example available inorganic glue, epoxy resin.Inner sealant layer 4 adopts the high-temperature flexible binding material to be sealing adhesive, for example materials such as available silicon rubber, organic siliconresin by the hot zone.Outside quartzy far-infrared tube 5, be provided with protection network 7.Protection network 7 can be connected on the flange 2.
Thermal convection causes that low frequency oscillation to the infringement of quartzy far-infrared tube and the anti-seismic performance that improves transportation and use, can be provided with flexible antishock device on quartzy far-infrared tube 5 when avoiding heating.This device can be made up of anti-vibration protected 8 and antirattle spring 9, and anti-vibration protected 8 perforate is inserted on the quartzy far-infrared tube 5, and antirattle spring 9 one ends and anti-vibration protected 8 hook connect, the other end and protection network 7 hooks company.
Quartzy far-infrared tube 5 can two ends extraction electrode line, also can single-ended extraction electrode line 1.Quartzy far-infrared tube 5 sides are provided with temperature control organ pipe 6, so that put into temperature-sensing element.
