The plasma fire head comprises a front cavity, a support saddle, a rear cavity, a nozzle, a tungsten electrode and a ceramic housing, wherein the support saddle is used for fixing the front cavity and the rear cavity, adopts a non-metal material and has an insulting role; the front cavity is fixed at the front end of the support saddle; the rear cavity is fixed at the rear end of the support saddle; the nozzle is mounted on the front cavity and is encircled at one end of the tungsten electrode; the tungsten electrode is mounted on the rear cavity; the ceramic housing is sleeved on the tungsten electrode and positioned between the tungsten electrode and the front cavity, can fix the tungsten electrode, and has the function of insulation; a channel is formed at the middle part of the support saddle and can be filled with argon; a processing cooling water channel is formed inside the support saddle; the front cavity and the rear cavity are fixed on the support saddle through bolts and are filled with cooling water; a shallow slot capable of being filled with argon is formed on the outer edge of the ceramic housing; and the length of the tungsten electrode is adjustable.
Description
Technical field
The utility model relates to a kind of plasma flame producer, relates in particular to a kind of plasma duration and degree of heating of sealing-in quartz glass tube in glove box that is used in the metal halide lamp manufacturing processed.
Background technology
The application of metal current halide lamp (Metal-halogen lamp) is very extensive.But on Metal-halogen lamp was made, particularly improve on the quality of Metal-halogen lamp fluorescent tube sealing-in and the efficient was the difficult point of industry always.Such as in common automobile Metal-halogen lamp manufacturing processed, the sealing-in fluorescent tube generally need add metal halide pill, mercury etc. in glove box, charge into xenon then, again with the fluorescent tube scorification, xenon etc. is enclosed in the fluorescent tube.Generally be to use coal gas, oxygen flame sealing-in now because the oxygen combustion of coal gas needs water oxygen, so sealing-in can not in glove box, carry out, and can only in glove box, finish annotate mercury and annotate ball after, take glove box again and take out outward and fill with the sealing-in of coal gas oxygen flame.But the fluorescent tube quality and the efficient of this traditional fluorescent tube sealing-in way are lower.
The utility model content
The technical problems to be solved in the utility model provides a kind of plasma duration and degree of heating that is used for the sealing-in quartz glass tube, can use in the Metal-halogen lamp manufacturing processed, with plasma fire sealing-in Metal-halogen lamp fluorescent tube, avoids fluorescent tube inside to contact with air, improves the quality of products.
For solving the problems of the technologies described above, the plasma duration and degree of heating that the utility model proposes comprises: preceding cavity, bearing, rear chamber, nozzle, tungsten electrode, ceramic jacket, cavity and rear chamber before wherein bearing is used for fixing, adopt non-metallic material to play insulating effect, preceding cavity is fixed on the bearing front end; Rear chamber is fixed on the base rear end; Before nozzle is installed on the cavity and around an end of tungsten electrode; Tungsten electrode is installed on the rear chamber; Ceramic jacket is placed on the tungsten electrode, and between tungsten electrode and preceding cavity, fixedly tungsten electrode also plays insulating effect.Above-mentioned bearing middle part has passage can lead to argon gas and there is the processing cooling-water duct inside; Forward and backward cavity is by being bolted on the bearing and all there is water coolant inside; The ceramic jacket outer rim has the shallow slot that can lead to argon gas; The length of tungsten electrode can be regulated.
The utility model is owing to adopt plasma arc sealing-in quartz glass tube in design, operations such as the fluorescent tube that must do outside glove box originally vacuumizes, inflation, sealing-in are finished in glove box, avoid Metal-halogen lamp fluorescent tube inside to contact, effectively improve the Metal-halogen lamp quality product with air.
Description of drawings
Fig. 1 is the diagrammatic cross-section of the plasma duration and degree of heating of a specific embodiment of the utility model, wherein: cavity, 2 bearings, 3 rear chambers, 4 nozzles, 5 tungsten electrodes, 6 ceramic jackets before 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 1, be specific embodiment of the utility model.This plasma duration and degree of heating comprises preceding cavity 1, bearing 2, rear chamber 3, nozzle 4, tungsten electrode 5 and ceramic jacket 6.Wherein: preceding cavity 1 is by being bolted on the bearing 2, and there is water coolant its inside, can reduce temperature at work; 4 at nozzle is installed on the preceding cavity 1; Rear chamber 3 is by being bolted on the bearing 2, and also there is water coolant its inside, plays cooling effect at work; Tungsten electrode 5 is installed on the rear chamber 3, and the other end then leads to nozzle 4, and the length of this tungsten electrode can be regulated by need of work.Ceramic jacket 6 plays fixedly tungsten electrode and insulating effect between tungsten electrode 5 and preceding cavity 1, its outer rim leaves the groove of logical argon gas, communicates in the ar gas passage of bearing 2; Bearing 2 is used for fixing forward and backward cavity, and it adopts the non-metallic material manufacturing can play insulating effect, and the inner processing of bearing cooling-water duct plays the cooling effect, at the bearing middle part ar gas passage that blows electric arc is arranged in addition.When real work, produce plasma arc between nozzle 4 and the tungsten electrode 5, by argon stream electric arc is blown out, the high temperature of plasma arc can be the silica glass scorification, thus effective sealing-in Metal-halogen lamp fluorescent tube.
In sum, owing to adopt above-mentioned plasma duration and degree of heating structure fire sealing-in Metal-halogen lamp fluorescent tube, several procedures of finishing outside glove box in the original Metal-halogen lamp manufacturing processed are finished in glove box.Fluorescent tube vacuumizes, inflation, and sealing-in is finished in glove box, can avoid Metal-halogen lamp fluorescent tube inside to contact with air, thereby effectively improve Metal-halogen lamp fluorescent tube sealing-in efficient and quality product.
Above-described is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present utility model.
