Abstract

The utility model relates to an instrument for measuring paraffin colour. The instrument is composed of a visual measurement mirror system, a colour comparing plate system, a colour comparing tank system and a light source system. Due to the adoption of the light source system, the structure of a light path is more reasonable, and the colour is clear and identifiable. Both sides of a sample colour comparing tank are provided with an insulating device to guarantee accuracy of measuring result of the paraffin colour. The lower side of the sample colour comparing tank is provided with a paraffin receiving disc, and waste paraffin spilled from a colour comparing vessel naturally flows into the paraffin receiving disc to guarantee normal operation of the instrument.

Description

Paraffin determination of colority instrument

The utility model is an instrument of measuring pertroleum wax series products colourity about a kind of, specifically, is the instrument of measuring paraffin colourity after the UV-irradiation about a kind of.

Paraffin generally is white solid, but when containing heterogeneous ring compound such as a certain amount of sulphur, nitrogen in the paraffin, along with storing or the increase of service time, the color of paraffin can be deepened gradually, therefore, the color of paraffin is to weigh an important indicator of paraffin quality after the UV-irradiation.

The mensuration of colourity is to adopt SH/T0403-92 type paraffin determination of colority instrument after the existing paraffin UV-irradiation, and this instrument is owing to unreasonable structure, and instrument does not have light-source system, makes that the color identification is unclear.The standard color chips of instrument color board adopts pmma material to make, and along with the instrument prolongation of service time, the color chips of pmma material can take place aging and make and darken, and therefore, the serviceable life of instrument is shorter.Do not have heating and heat-insulating device in the sample cell, the paraffin of heat can produce crystallization in the cuvette in measuring process, influences the accuracy of measurement result.And the no wax discharging port in sample cell bottom, the wax that overflows in the cuvette in measuring process can condense in the bottom of sample cell.

It is clear that the purpose of this utility model provides the identification of a kind of color, the color chips color accurately and reliably, the cell temperature can be controlled, instrument that can rapid and accurate determination paraffin colourity.

The utility model paraffin determination of colority instrument comprises range estimation mirror system, color board system, cell system, light-source system composition, wherein light-source system comprises lamp house, light source, filter glass, reflective mirror, light source and cell system are separated by by filter glass, and light source is between reflective mirror and filter glass.

Fig. 3 is the utility model light path synoptic diagram.

Describe the utility model 26S Proteasome Structure and Function in detail below in conjunction with accompanying drawing.

As shown in Figure 1, the instrument that provides of the utility model is made up of range estimation mirror system 1, color board system 2, cell system 3, light-source system 4.

As shown in Figure 3, described range estimation mirror system is made up of imaging hole 5, lens 6, lens 7, reflective mirror 8, reflective mirror 9, prism 10 and lens barrel.Respectively there is tilting reflective mirror 8, the reflective mirror 9 of a symmetry prism 10 both sides, and reflective mirror 8, reflective mirror 9 cooperate with prism 10, will become directional light by the beam reflection of sample cell and blank cell.Apart from retractable,, two bundle directional lights of prismatic reflection can be focused on imaging hole 5 between lens 6 and the lens 7 by regulating the spacing of lens 6 and lens 7.

As shown in Figure 2, the color board system is made up of standard colorimetric plate 11, spur bevel gear 12, drive link 13, standard color chips 14, reversible stepper motor 16.Described standard colorimetric plate 11 is circular, studs with 9 different color standard glass color chips 14 on it.On the shell of analyzer, offer colourity indicator hole 15.

As seen from Figure 1, Figure 2, the cell system is made up of blank cell 17, sample cell 18, grafting wax dish 19.Blank cell 17 and sample cell 18 are rectangular parallelepiped, and described sample cell 18 both sides are added with electric heating piece 20, and the top of sample cell 18 has insulation cover.Sample cell bottom has a de-waxing hole 21, and the sample cell is communicated with the grafting wax dish 19 of bottom, and grafting wax dish 19 is a drawer structure.

As shown in Figure 2, light-source system is made up of lamp house 22, light source 23, filter glass 24, reflective mirror 25, and lamp house 22 is separated by with filter glass 24 with the cell system.The light that is sent by daylight lamp is divided into two-way, and one the tunnel enters in the sample cell through filter glass 24, and the light that sees through sample reflexes to prism 10 by catoptron 8, is reflected into straight line light by prism 10 again and enters lens 7 and lens 6 respectively; Another road enters in the blank cell through filter glass 24, and the light that sees through blank cuvette reflexes to the another side of prism 10 by catoptron 9, is reflected into directional light by prism 10 again and enters lens 7 and lens 6 respectively.

Using method of the present utility model is: will be higher than the about 10 ℃ wax of fusing point and pour in the quartz colorimetric utensil, put into the sample cell then, again the quartz colorimetric utensil of another identical sky is put into blank cell, opening sample cell heating arrangement makes wax be in temperature constant state, the turn on lights source, adjust the spacing of lens 6 and lens 7, two-way light is focused on the imaging hole respectively.Press reversible stepper motor rotation standard colorimetric plate, make the two-way light color identical, the numerical value that this moment, front panel colourity indicator hole showed is the color number of wax sample.

The utility model is applicable to the colourity of evaluating with paraffin behind the UV-irradiation, and then the ultraviolet of evaluation paraffin Light stability, the utility model also are applicable to the colourity of evaluating with microwax behind the UV-irradiation.

Paraffin determination of colority instrument of the present utility model has following advantage:
