Description
Technical field
The utility model relates to a kind of device for measuring pertroleum wax light stability, especially a kind of light stability determining instrument improving the pertroleum wax of accuracy of detection and reliability.
Background technology
Pertroleum wax has a wide range of applications in industries such as food, medical treatment, chemical industry.The principal ingredient of pertroleum wax is n-alkane, but the labile elements such as S, N, O compound also containing less isoparaffin, naphthenic hydrocarbon, aromatic hydrocarbons and trace, these labile elements are easily oxidized under ultraviolet and hot work, cause darkening of pertroleum wax, use value reduces, for this reason, need detect the light stability of pertroleum wax.At present, measure pertroleum wax light stability can basic skills be by cured for oil to be placed in planchet and to be placed in can heat, in the confined chamber of temperature control, when the temperature of control confined chamber is 90 DEG C ± 2 DEG C, start ultraviolet source, to pertroleum wax sample irradiation certain hour, again the sample of variable color and standard color sample are contrasted, the light stability of judgement sample.Existing UV-irradiation has direct irradiation, perspective illumination is penetrated, the modes such as the employing arc reflection hood-shaped one-tenth reflected light irradiation also had, but all can not ensure the homogeneity of sample illumination, is difficult to ensure accuracy of detection; In addition, although some determinators adopt optical fiber that ultraviolet light is drawn heated for controlling temperature confined chamber, can only detect and whether have illumination, cannot detect, controlled light intensity, the reliability of testing result is lower.
Summary of the invention
The utility model is for the above-mentioned technical matters existing for prior art, provides a kind of light stability determining instrument improving the pertroleum wax of accuracy of detection and reliability.
Technical solution of the present utility model is: a kind of light stability determining instrument of pertroleum wax, there is heated for controlling temperature confined chamber, support is had below described heated for controlling temperature confined chamber, the base plate of heated for controlling temperature confined chamber is fixed with hollow rotating shaft, be connected to by the rotary bracket of actuator drives with hollow rotating shaft, on rotary bracket, be fixed with planchet; Above described rotary bracket, be fixed with spherical reflector, ultraviolet source fluorescent tube is horizontally fixed on spherical reflector; The quartz glass light-guiding pillar through heated for controlling temperature confined chamber base plate is built-in with at hollow rotating shaft, be provided with outside heated for controlling temperature confined chamber and corresponding with quartz glass light-guiding pillar ultraviolet ray intensity sensor is set, be connected to ultraviolet ray intensity controller with ultraviolet ray intensity sensor.
The utility model adopts spherical reflector and sample is placed on rotary bracket, can make that reflection ray is vertical, uniform irradiation on sample, improve accuracy of detection; The confined chamber of light source from high temperature can be drawn by quartz glass cylinder light-guiding pillar, because quartz glass cylinder has certain sectional area, by ultraviolet ray intensity sensor and controller, can detect and control the ultraviolet ray intensity in unit area, improve the reliability of testing result.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
As shown in Figure 1, there is heated for controlling temperature confined chamber 1 same as the prior art, heating and temperature controlled closed container can be realized, have support 2 below heated for controlling temperature confined chamber 1 with prior art difference, the base plate of heated for controlling temperature confined chamber 1 is fixed with hollow rotating shaft 3, be connected to hollow rotating shaft 3 rotary bracket 5 driven by gearing 4, gearing 4 can be made up of stepper motor and gear drive, is evenly fixed with four planchets 6 on rotary bracket 5; Be fixed with spherical reflector 7 above described rotary bracket 5, ultraviolet source fluorescent tube 8 is horizontally fixed on spherical reflector 7, and spherical reflector 7 can be Surface of Sphere or ellipsoidal surface, ensures that reflection ray vertical irradiation is on sample; Hollow rotating shaft 3 internal fixtion have through heated for controlling temperature confined chamber 1 base plate quartz glass light-guiding pillar 9(namely with quartz glass processing the cylinder with certain xsect), be provided with outside heated for controlling temperature confined chamber 1 and corresponding with quartz glass light-guiding pillar 9 ultraviolet ray intensity sensor 10 is set, be connected to ultraviolet ray intensity controller 11 with ultraviolet ray intensity sensor 10.Ultraviolet ray intensity controller 11 is made up of PLC control unit etc., realizes controlling ultraviolet ray intensity.
