Oxygen index (OI) refers under prescribed test conditions, and sample maintains smooth combustion (i.e. aerobic in oxygen-nitrogen mixture stream
Burning) needed for minimum oxygen concentration, represented i.e. after the substance combustion with the numerical value of the percentage by volume shared by oxygen, (can be protected
Hold the concentration of volume percent of most hypoxia in oxygen-nitrogen mixture body required when burning 50mm length or burning time 3min).Its
As judgement material in atmosphere with flame contact when the complexity burnt it is highly effective.
According to national standard GI3/T2406.2-2009《Plastics determine burning behavior with oxygen index method》Its test philosophy is:
The sample vertical support of specified size has finite concentration bottom-up by rule in which in the transparent combustion barrel of a given size
Determining the mixed gas of the oxygen and nitrogen of flow rate, sample upper end being lighted with lighter, sample starts timing when burning, and observes examination
Sample combustion case, records burning time and burning length, by comparing with numerical value specified in national standard during fray-out of flame
Determine experimental result.In actual test, according to sample, combustion case estimates an initial oxygen concentration, Ran Hougen in atmosphere first
According to experimental result by " rise one and drop method " principle, minimum oxygen concentration needed for sample burning is progressively found.
The mixing of nitrogen and oxygen when prior art is tested typically adjusts the flow of nitrogen and oxygen to realize not on year-on-year basis
The mixing of example, but the flow control valve price of existing tester is high, complex structure, and adds additional joint, pipeline etc.
Equipment, makes the price of tester remain high always.Actually only need in some cases simply determine the general of oxygen index (OI)
Scope, and do not need accurate measurement, it is therefore necessary to design a kind of simple structure, low-cost for oxygen index (OI) simple measuring
Instrument.
The content of the invention

The other end is close to the lower surface of mixing pan；Nitrogen switch is connected with one end of nitrogen tube, the other end and mixing pan of nitrogen tube
Lower surface be close to；
Oxygen outlet, the nitrogen pore of multiple insertions be set along its axis direction on described mixing pan, described oxygen outlet, nitrogen
Pore arranges multiple along the radial direction circular symmetric of mixing pan, and the diameter of multiple oxygen outlets is each unequal, multiple nitrogen pores
Diameter is each unequal；Described oxygen hose is connected with an oxygen outlet, and described nitrogen tube is connected with a nitrogen pore；
The upper surface of described mixing pan is connected with the lower surface of mixing drum, the opening of mixing drum upper end and one end of sebific duct
Connection, the other end of sebific duct are connected with the opening of combustion barrel bottom, and combustion barrel is fixed in mensure case, the top of the combustion barrel
Hemispherical bell glass is set, is arranged in described combustion barrel.
Preferably, described oxygen switch, nitrogen switch are electromagnetic switch, and oxygen switch, nitrogen switch are by wireless
Mode is connected with controller.
Preferably, described mixing pan is connected with motor by train of reduction gears.
This utility model has the advantages that：The inconsistent oxygen outlet of multiple diameters, nitrogen pore are set, and are led to
The rotation for crossing mixing pan 7 selects different oxygen outlets, nitrogen pore to be connected with oxygen hose, nitrogen tube respectively, to change oxygen and nitrogen
The ratio value of oxygen mixture, so instead of flow control valve, greatly reduces cost；Connecting line is also without extra
Control and the detection circuit of flow control valve are set, simplify analyzer structure.
