Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is described further:
As shown in Figure 1, totally-enclosed automatic ration sample introduction determination of trace water system, comprise automatic sampling apparatus 1, automatic sampling apparatus 1 comprises substrate 11, linear electric motors 12, sampling injector 13, linear electric motors 12 are installed on the substrate 11, the handle 131 of sampling injector 13 is connected with linear electric motors 12, and the injection head 132 of sampling injector 13 is communicated with by the left part of pipeline with U-shaped stopple coupon 2, on the connecting pipeline of sampling injector 13 and U-shaped stopple coupon 2 first solenoid valve 14 is set;
The right part of U-shaped stopple coupon 2 is communicated with electrolytic cell 3 by pipeline, and second solenoid valve 31 is set on this connecting pipeline;
The right part top of U-shaped stopple coupon 2 is communicated with lubricating cup 9 by pipeline, and the 3rd solenoid valve 91 is set on this connecting pipeline;
The right part of U-shaped stopple coupon 2 arranges optoelectronic switch 6, and optoelectronic switch 6 can move up and down along the right part of U-shaped stopple coupon 2, that is regulates the injection rate IR of sample to be tested;
Linear electric motors 12, heating blower 4, optoelectronic switch 6, air pump 7, first solenoid valve 14, second solenoid valve 31, the 3rd solenoid valve 91, the 4th solenoid valve 51, the 5th solenoid valve 81 all electrically connect with a controller.
Principle of work of the present invention and the course of work are as follows:
As shown in Figure 1, when the linear electric motors 12 on being fixed on substrate 11 rotate with the speed of 0.5mm/s, be installed in the sampling injector 13 on the linear electric motors 12, be generally the 100mL syringe and seal with Capsule; By 131 motions of linear electric motors 12 pushing syringe handles, sample in the sampling injector 13, from injection head 132 and connecting line thereof, enter stopple coupon 2 by first solenoid valve 14, this moment, first solenoid valve 14, the 3rd solenoid valve 91 were set to open mode by controller;
When the liquid level in the U-shaped stopple coupon 2 arrives the height of optoelectronic switch 6 settings, optoelectronic switch 6 passes to controller with signal, send control signal by controller and give linear electric motors 12, thereby control linear electric motors 12 stop operating, and control first solenoid valve 14 simultaneously, the 3rd solenoid valve 91 cuts out;
Then, second solenoid valve 31, the 4th solenoid valve 51 are set to open mode by controller, heating blower 4 is with the hot blast of 50 ℃ of constant temperature, after carrying out finish-drying by 5 pairs of air of two drying bottles, be blown into U-shaped stopple coupon 2, utilize air pressure, the whole samples with in the U-shaped stopple coupon 2 are pressed in the electrolytic cell 3 by second solenoid valve 31; Afterwards, second solenoid valve 31, the 4th solenoid valve 51 are set to open mode by controller, thereby finish airtight, the quantitative sample injection of sample; Sample introduction finishes, and just can carry out sample testing work in electrolytic cell 3.
Sample testing finishes, and carries out pipeline and cleans.By controller control the 3rd solenoid valve 91, the 5th solenoid valve 81 is opened, the organic solvent of perfusion in the washer bottle 8, comprise absolute ethyl alcohol, sherwood oil, acetone etc., under the effect of air pump 7, in washer bottle 8, flow out, to U-shaped stopple coupon 2, by the road waste liquid is entered lubricating cup 9 more by the road, namely 2 cleanings finish to the U-shaped stopple coupon earlier; Afterwards, again by controller opens second solenoid valve 31, with the pipeline between a small amount of washing lotion cleaning U-shaped stopple coupon 2 and the electrolytic cell 3; Can allow waste liquid come through above-mentioned two paths shunting like this, the small part waste liquid is flowed in the electrolytic cell 3, be unlikely to consume the electrolytic solution in the electrolytic cell 3 like this, the serviceable life of extended period electrolyte inside.
After last time detection finished, clean U-shaped stopple coupon 2 and respective line, control the 3rd solenoid valve 91 by controller and close this moment, opens second solenoid valve 31, the 5th solenoid valve 81; Open air pump 7, the organic solvent of perfusion in the airtight washer bottle 8 will be contained in, being pressed into U-shaped stopple coupon 2 and pipeline cleans, then, the 5th solenoid valve 81 cuts out, and the 4th solenoid valve 51 is opened, 4 runnings of controller control heating blower, freeze-day with constant temperature air in the drying bottle 5 is blown into U-shaped stopple coupon 2 and pipeline, and they are dried up, in order to using next time.
When needing other sample of replacing to detect, after above-mentioned cleaning with an organic solvent, also will be with sample to be tested to U-shaped stopple coupon 2 and respective line flushing, at this moment, by controller first solenoid valve 14, second solenoid valve 31, the 3rd solenoid valve 91 are opened, allow a certain amount of sample stream through U-shaped stopple coupon 2 and respective line, be not subjected to the influence of other sample to guarantee this this measurement.
All pipelines can use corrosion resistant four fluorine tube.
As above, carry out application of sample with 12V, 12 pairs of samples of 1A linear electric motors and measure, realized automatic sampling, reduced artificial sample introduction error, improved work efficiency greatly; Closure with high-accuracy each pipeline of solenoid control, the inner abrasive disc of solenoid valve selects for use the polytetrafluoro abrasive disc should have oil resistant, characteristics such as acidproof, alkaline-resisting, and closed performance height is stablized, the permanently effective influence of stopping the sample external factor of energy has improved accuracy of measurement and repeatability; Adopt a kind of U-shaped (or V-arrangement) stopple coupon 2 of height printing opacity, utilize the liquid level of optoelectronic switch 6 test samples, can guarantee the accuracy of sample size; After adopting heating blower 4 to produce air pressure, through the moisture in the middle of dual drying bottle 5 filtered airs, guarantee to enter the air adiabatic drying of U-shaped (or V-arrangement) stopple coupon 2, avoided the influence of the moisture in the outside air to sample; Heating blower 4 makes air themperature reach 50 ℃ and constant temperature, and temperature error reaches ± and 0.5 ℃, do not change under stationary temperature with the volume that guarantees U-shaped (or V-arrangement) stopple coupon 2, guarantee the accuracy of sample size; Utilize air pump 7 that anhydrous organic solvents such as absolute ethyl alcohol are compressed into each pipeline, pipeline is cleaned, use the dry air of 50 ℃ ± 0.5 ℃ of constant temperature to dry up then, not only guarantee each pipeline drying, cleaning, increase the service life; Utilization has the glass tube of mill plug as the sample introduction pipe of electrolytic cell 3, puts into below the electrolysis liquid surface, and the purpose of selecting glass tube for use is that it has stable chemical property, can not be corroded by electrolytic solution, improves the serviceable life of equipment; Utilize the discharge of solenoid control sample waste liquid, can play and with the sample detergent line time, to be unlikely to allow more sample enter electrolytic cell 3, to increase the serviceable life of electrolytic solution.The total system pipeline designs for totally-enclosed, and sample does not contact with extraneous moisture, has reduced extraneous moisture greatly to the influence of sample, has improved accuracy of analysis, has reduced artificial sample introduction error, can satisfy under the big condition of ambient humidity and use.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
