The equipment is composed of a lamp chamber, a constant temperature chamber and an electric appliance chamber. The utility model has the advantage of reasonable structure. The utility model guarantees stable ultraviolet irradiation intensity and constant temperature of the constant temperature chamber, and therefore, the utility model guarantees accuracy and precision of the measuring result of wax light stability to accurately determine the grade of the wax. The measuring process adopts programmed control by a microcomputer. The utility model realizes full automation of the control of temperature, irradiation intensity and time in the checking process and raises work efficiency.
Description
The invention belongs to a kind of paraffin quality grade inspection machine in the petrochemical industry.
In the petroleum refinery process, a kind of product is arranged, can in the development of the national economy, be widely used in paraffin.In order to determine the paraffin quality grade, need paraffin is detected definite grade, so that be applied to different industries.
The present invention detects in the used instrument the paraffin quality in the past, and the prior art the most approaching with the present invention is that China's the seventies absorbs the SH/T 0404-92 type wax light stability measuring instrument that designs voluntarily behind the foreign technology.As shown in Figure 1: light source 1 is directly installed in the constant temperature enclosure 2, and electric fan 3 is from the below air-supply of constant temperature enclosure 2.
This instrument is because unreasonable structure, the uv energy that radiation of light source goes out, be subjected to the influence of environment, radiant illumination is stable inadequately in testing process, thereby have influence on degree of accuracy and precision to the wax light stability testing result, give and determine that the paraffin quality grade causes difficulty, can have a strong impact on the correct application of paraffin, very cause sometimes and can cause the tremendous economic loss.
In order to overcome above-mentioned shortcoming, the objective of the invention is to design a kind of brand-new instrument, in order to improve degree of accuracy and precision, realize the robotization of testing process simultaneously to the wax light stability testing result, increase work efficiency greatly.
Detailed content of the present invention is as shown in Figure 2: be made up of lamp house (4,5,6,7), constant temperature enclosure (8,9,10,11,12,13,14,16), ventiduct 15, electric apparatus room (17,18,19,20).
Lamp house is made up of upper box 4, view window 5, catoptron 6, light source 7; Constant temperature enclosure is made up of Ultraviolet sensor 8, quartz glass 9, examination ware frame 10, constant temperature oven 11, axial flow blower 12, temperature sensor 13, ventilation base plate 14, middle casing 16; Electric apparatus room is made up of power-supply system 17, Control System of Microcomputer 18, electric-control board 19, lower box 20.
In upper box 4, the reflecting surface of catoptron 6 is towards the bottom surface of upper box 4, and fixing with upper box 4, light source 7 places the focus place of catoptron 6, and view window 5 is arranged on the front of upper box 4; Constant temperature oven 11 is installed in middle casing 16, the upper level of constant temperature oven 11 is installed quartz glass 9, ventilation base plate 14 is installed in the bottom, on the symmetric position of center, the left and right sides, front and back four examination ware framves 10 are being installed on the ventilation base plate 14, at the center of ventilation base plate 14 mounting temperature sensor 13, in the front and back of temperature sensor 13 rectilinear direction Ultraviolet sensor 8 is installed, an axial flow blower 12 is respectively installed in the both sides outside constant temperature oven 11; Be provided with ventiduct 15 between middle casing 16 and the lower box 20, be arranged side by side power-supply system 17 and Control System of Microcomputer 18 in lower box 20, the front of lower box 20 is provided with control panel 19.
Principle of work explanation of the present invention: the radiation flux that light source 7 sends, part direct irradiation is on examination ware frame 10, another is partly reflexed on the examination ware frame 10 by catoptron 6, in the radiation flux of light source 7, ultraviolet portion is had an effect with the paraffin on the examination ware frame 10, color changed after paraffin received ultraviolet light irradiation, determined the paraffin grade according to the paraffin color.
Infrared part in the radiation of light source flux makes the constant temperature enclosure heat temperature raising.For guaranteeing that paraffin is in molten state, the temperature in the constant temperature oven 11 reaches by axial flow blower 12 air-supplies that are installed in both sides regulates the temperature control effect, and whole testing process is controlled by microsystem.
Good effect of the present invention: the present invention is rational in infrastructure, has guaranteed the stability of uv radiation intensity and the constant temperature of constant temperature enclosure, thereby has guaranteed the degree of accuracy and the precision of wax light stability measurement result, can accurately determine the paraffin grade.Measuring process adopts microcomputor program control, has realized the testing process full-automation, has improved work efficiency greatly.
Description of drawings: Fig. 1 is the structural representation of prior art, and Fig. 2 is a structural representation of the present invention, and Figure of abstract also adopts Fig. 2.
Most preferred embodiment: three tank materials of upper, middle and lower adopt cast aluminium, light source 7 to adopt high-pressure sodium lamp, and catoptron 6 adopts the material of parabolic aluminium alloy catoptron, quartz glass 9 to adopt JGS
8, temperature sensor 13 adopts PT
100, UV sensor 8 adopts the ultraviolet silicon photocells to add ultraviolet filter, the material of ventilation base plate 14 adopts aluminium sheet, the material of examination ware frame 10 adopts stainless steel, microcomputer adopts 51 machine systems.
