Description
Technical field
The present invention relates to the technical field of metal spectrum analysis, specially hollow cathode lamp device.
Background technology
Blade in the market, the main material of axle are all to be made up of dystectic alloy, but in manufacturing process,
The inside of material can be mixed into the low-melting-point metal impurity such as some such as stannum, lead, bismuths, causes during blade, axle run up,
These low-melting-point metal impurity first melt, and then form crack on blade, axle, cause the working life of these frame for movements
Short.
So-called plasma source in spectrum analysis, is often referred to be similar in appearance a class charging source of flame.Mesh
Before the most frequently used have three classes: i.e. induction coupled plasma torch (ICP), direct-current plasma bright eruption (DCP) and microwave is inducted
Gas ions torch (MIP).For MIP, although allowing micro-sampling, air consumption is little, and power mensuration low, easy is nonmetal, but right
Most metal detection limits are poor, Interelement interference serious, needs helium, is therefore mainly used in the detector of chromatography.ICP and
This two classes plasma source of DCP has preferable analytical performance, has the most been applied to Atomic Emission Spectrometer AES.But it is existing
This two classes plasma source of ICP and DCP detection be limited to 0.001% detection limit, for lower loading foreign metal its cannot
Detect.And in existing spectrogrph, hollow cathode lamp functions only as the effect of luminescence, and its effect is single.
Summary of the invention
For the problems referred to above, the invention provides hollow cathode lamp device, it can be by hollow cathode lamp internal junction
Close external spectrogrph, directly detect the content of low-melting impurities in alloy to be detected, and its precision can reach
0.00001%～0.0001%, its accuracy of detection is high.
Hollow cathode lamp device, its technical scheme is such that it and includes that glass tubing, top end cover, cushion block, rear portion are fixed
Block, the front end of described glass tubing is provided with described top end cover, and the rear end of described glass tubing is provided with described cushion block, and described cushion block is tight

End be welded to connect nickel sheet structure, the rear end of described tungsten bar is plugged in inside described cushion block, described graphite electrode towards described
One end of tungsten bar is provided with hollow object placing cavity, places alloy to be detected in described hollow object placing cavity, and the inside of described glass tubing is filled
Full noble gas.
It is further characterized by outside the outer ring surface of described glass tubing being provided with fixing bar, every described fixing bar
Two ends connect described top end cover, cushion block respectively, and are fastenedly connected by fixing screw；
It is provided with silicagel pad between the contact surface of described glass tubing and described top end cover；
Described silicagel pad, top end cover are run through in the front end of described connecting rod, and plug cover is loaded on the anterior suit of described top end cover
In hole, described plug blocks the front portion of described connecting rod.
After using the structure of the present invention, graphite electrode is as the negative electrode of hollow cathode lamp, the hollow object placing cavity of graphite electrode
Interior placement alloy to be detected, is welded with the tungsten bar of nickel sheet structure as anode, when applying high voltage between two-stage, to be detected
Low-melting-point metal in alloy is the most luminous, refractory metal luminescence afterwards, is divided by spectrogrph according to the spectrum that its metal is luminous
Analysis, it is possible to analyze the content of low-melting impurities drawing alloy to be detected, and its precision can reach 0.00001%～
0.0001%, accuracy of detection is high.
