V reflection groove, and the reflection groove is just to the tuyere.The bottom plate set in preheating cavity bottom and is worked as just to wire netting
Warm-air pipe is sprayed after high temperature air, and high temperature air is directly gathered in reflection groove through wire netting, because the section of reflection groove is in V
Shape so that high temperature air is applied directly on the lower surface of glass tube by the reflecting surface of reflection groove, and then ensure glass tube
Two surfaces are sufficiently heated up and down.
The main jet head is spiral nozzle with secondary shower nozzle, and the distance of the main jet head end away from branch pipe is more than secondary shower nozzle
Distance away from branch pipe.Preferably, multiple main jet heads are staggered with multiple secondary shower nozzles, and the water residing for two kinds of shower nozzle
Flat height is different, and uses spiral nozzle so that the radiation scope of main jet head and secondary shower nozzle is complementary, to avoid the upper of glass tube
Occur dead angle on lower two surfaces and cause the portions under heat degree to be unable to reach softening temperature.
The present invention compared with prior art, has the following advantages and advantages：
The present invention is applied to the pre-heating mean of electrothermic film element, in heating chamber, and multiple main jet heads on branch pipe spray with secondary
Head is heated to glass tube simultaneously so that the temperature in whole heating chamber reaches the softening temperature of glass tube, while ensureing glass
The each several part of glass pipe is heated evenly, it is to avoid local heating occur excessively, and the inadequate phenomenon of the heated dynamics of remainder occurs, to protect
Demonstrate,prove performance of the glass tube before spraying plating and meet spraying plating standard.
