Embodiment
Referring to Fig. 1 and Fig. 2, automatic sampling of the present invention and treating apparatus are used mark 25 chief representatives.But in order to realize the problem of spot sampling and processing, design of the present invention is: a kind of portable water quality heavy metal element on-the-spot sampling and treating apparatus automatically, it comprises sampling pump 22, sampler chamber 23, sampling hut 3 and sampling rotating mechanism 24, the rising pipe of sampling pump 22 is communicated with sampler chamber 23 imports 19, is provided with spring valve 17 between sampler chamber 23 and the extraction chamber 3.
The roughly process of sampling is: sample 20 → sampling pump 22 → sampler chamber 23 imports 19 → spring valve 3 → coiled filament A of 17 → extraction chamber → sampling rotating mechanism 24 rotation → coiled filament B.
After the sampling, can pass through 11 pairs of sample heat treated of electrode.
Sampler chamber comprises solenoid valve A1, piston 2 and spring valve 17,2 to-and-fro movements of solenoid valve A1 control piston, and 17 actions of piston 2 control spring valves are opened spring valve 17, and spring valve 17 separates sampler chamber 23 imports and extraction chamber 3.
The structure of described sampling rotating mechanism comprises: driving mechanism and rotating mechanism, driving mechanism comprises solenoid valve B12, control lever 14, feeding ratchet 13 and ratchet 6, solenoid valve B12 upper end horizontal direction is provided with control lever 14, and these control lever 14 rear ends are connected with spring 10; Control lever 14 front end sleeves are on feeding ratchet 13, and ratchet 6 is contained on the support axle 21-1 of support 21, ratchet 13 and ratchet 6 engagements; The sampling rotating mechanism comprises two dwangs 5, two turrets 7 and coiled filament seat A4, B8, the upper and lower respectively symmetry of two dwangs 5 is inserted on the ratchet 6, be set with turret 7 on the every dwang 5, coiled filament seat A4, B8 are contained in respectively and rotate up and down on the frame 7, and coiled filament seat top communicates with extraction chamber 3.
Extraction chamber's 3 one sides are communicated with zeolite pump 16.
At ordinary times, under unsampled duty, the sample liquid that sampling pump 22 pumps into enters import 19, enters in the chamber through inlet channel 18, and the discharging tube on support (not drawing among the figure) is discharged again.
When needing sampling, control center sends instruction by instrument, solenoid valve 1 action promotes piston 2 and moves right, back down spring valve 17, sampler chamber 23 imports 19 are communicated with extraction chamber 3, sample 20 enters extraction chamber 3 from import 19, because the injection hole of extraction chamber 3 inflow points is very little, water sample is sprayed onto extraction chamber 3 with certain pressure from spray-hole.The amount of reagent that sprays into is several milligrams, and every part of liquor sample forms tight jet, can guarantee that 90% the solution of importing hits on the coiled filament A4.Extraction chamber 3 links to each other with zeolite pump 16 and condenser, can play the effect that vacuumizes and remove steam, and this part has condensation, makes sample remove moisture content under low temperature, low pressure, and remaining component to be measured is then stayed on the coiled filament A4.After sampling is finished, solenoid valve B12 opens, jacking control lever 14, control lever 14 drives feeding ratchet 13 and moves up and down, thereby ratchet 6 is rotated around support axle 21-1, ratchet 6 is when rotating, and with the coiled filament seat A4 Rotate 180 ° coiled filament B8 place of having taken a sample in top to the below, coiled filament B8 then Rotate 180 ° descends sub-sampling to the wait of coiled filament seat A4 place, top.
The filament that has new extraction sample directly occupies the cell of ion gun 9, and according to the fusing point different heating of compounds such as tested heavy metal component such as Pb, Hg, Cr, Cd, Fe, Zn, Mn, Cu, As to different temperature, filament adopts tungsten-rhenium alloy, heating-up temperature is controlled, with electron beam tested component is bombarded, make its abundant ionization, can improve the accuracy of measurement of instrument greatly.The metallic filament that measurement finishes is got back to the sampling hut from ion gun again, takes a sample next time.
The automatic sampling and the processing mechanism of portable water quality heavy metal element in-site measurement system can provide measuring system quantitative water sample automatically, and heavy metal substance to be measured is remained on the filament, heavy metal substance to be measured sent into ion gun automatically and to heating before it, improve Ionization Efficiency, this device also can be used in the instrument that other ultimate analysis is measured in the water.
Certainly, above-mentioned is not to be limitation of the present invention for example, under the present invention's design, can also change, replaces, retrofits and add, and should belong to protection scope of the present invention yet.
