Abstract
An electric heating tube is characterized in that the heating tube comprises an outer quartz tube and a quartz support is arranged inside the outer tube, and a carbon fiber knitted belt serving as heating element is uniformly wound around the quartz support in a spiral manner. The carbon fiber knitted belt is pre-knitted to different specifications according to the knitting density and technical parameters. Accordingly, the utility model has low requirement for carbon fiber filament, and both the short and long carbon fiber can be adopted to save materials; and the carbon fiber knitted belt of a certain specification can be wound uniformly according to the requirement for the electric heating tube, thereby simplifying process and achieving high production efficiency and uniform density. The utility model has firm structure, stable working performance, uniform temperature, and good illumination effect, and the heating element is prevented from deformation and has long service life.

Application number is that 03214690.6 Chinese patent application discloses a kind of carbon fiber electric heating tube, its structure is to be made of glass tube, heater, lead brace, porcelain insulating fixed block, power lead and connecting line, heater is arranged among the inner chamber of glass tube, the lead brace is locked in the inboard, end of glass tube, the porcelain insulating fixed block is arranged on the outside, end of glass tube, one end of power lead joins by the end of connecting line and heater, and the other end of power lead joins by glass tube, lead brace and porcelain insulating fixed block and power supply.Its defective is, because inhomogeneous its heating temp that causes of the fine and closely woven degree of heater is also inhomogeneous, and naked eyes look that illumination effect is not good, and the power departure is bigger, and heater is easy to distortion, bending, and useful life is shorter.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides that a kind of heater density is even, illumination effect is good, cost is low, the electric heating tube of long service life.
Technical problem to be solved in the utility model is to realize by following technical scheme.The utility model is a kind of electrothermal tube, comprises outer tube, is characterized in, described outer tube is a quartz ampoule, is provided with quartzy supporter in the described outer tube, and even spiral twines and is provided with the carbon fiber knit band as heater element on the quartzy supporter.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of electrothermal tube, be characterized in, the two ends of outer tube all are connected with the power supply lead wire of tape insulation porcelain spare, be provided with brace in the both ends of outer tube, one end of brace is connected with power supply lead wire, and the other end is connected with joint pin, and carbon fiber knit band both ends are connected with joint pin, described outer tube is provided with vacuum vent holes, also is filled with inert gas in the outer tube.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of electrothermal tube, be characterized in, quartz ampoule or the stuffed quartz support stick of described quartzy supporter for not sealing is provided with the Mo connecting line in the winding of the both ends, the left and right sides of quartzy supporter spiral, is used for fixing and connects carbon fiber knit band and joint pin.Quartzy supporter of the present utility model is quartz ampoule or the stuffed quartz rod that directly cuts into required size and specification, and two portions of quartz ampoule need not seal, and needn't vacuumize in the pipe yet, processes very convenient, and cost-saved.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of electrothermal tube is characterized in, the canoe of described connecting line is that spiral twines.
Technical problem to be solved in the utility model can also further realize by following technical scheme.Above-described a kind of electrothermal tube is characterized in, the winding spacing a=2-10 millimeter of described carbon fiber knit band.Preferred a=4-8 millimeter, further preferred a=5-7 millimeter.
Compared with prior art, heater element carbon fiber knit band of the present utility model is a kind of braid over braid that prelists and weave, and is divided into plurality of specifications by its count and technical parameter when braiding, therefore, it is lower to the filametntary requirement of material carbon, and length all can participate in braiding, can save raw material; When twining, only need to select for use the carbon fiber knit band uniform winding of certain specification to get final product by the requirement of electrothermal tube, its processing technology is very simple, the production efficiency height, the electrothermal tube density that is processed is even, sound construction, stable work in work, heating temp is even, and naked eyes look that illumination effect is splendid; Heater element is not easy distortion, long service life.Employing quartz materials such as outer tube of the present utility model are made, but antiultraviolet has environment protecting, and high temperature strength is big.The utility model electric thermal power in use is stable, is opening and is closing the impact that Shi Buhui produces the moment maximum power, is applicable to the warm lamp of electricity and the heater product of all sizes such as warmer, super bath, disinfection cabinet, dishwasher, heating lamp.
