Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as effect and the principle of work etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
As shown in Figure 1, this iodine abstraction reaction device connects vacuum pump 1 and reactor 15 by condensing container 13 dual-sides, and container bottom is connected with tapping bottle 14, plays buffer action during for tapping, and another side of reactor 15 is connected with CCl
4reagent bottle 17, above-mentioned all connections all connect by pipeline 18.The built-in stirrer 16 of reactor 15, stirrer 16 is that the taper of falling double helix adapts with the shape of reactor 15, stirrer 16 is made up of central shaft 161 and double helix paddle 162, and central shaft 161 is arranged on the axis of double helix paddle 162 and drives double helix paddle 162 to rotate.As shown in Figure 2, central shaft 161 is divided into two-section, and one is truncated into screwed son 21, and another is truncated into the female 2 coordinating with it, and such design is convenient to that the later stage removes and installs and the installation of cleaning device is below implemented.
When enforcement, first by screw thread, put-put 164 is connected with central shaft 161, then, opens vacuum pump valve 19, water sample, by charging aperture 36 injecting reactors 15, is then closed to the valve on charging aperture 36.Start vacuum condensation extracting, condenser 11 is down to zero the cooling medium in condensing container (ethanol) by condensation contact rod 12 following, is opening vacuum pump 1, will in reactor 15, be evacuated.Then, turn on agitator 16, under the double action of vacuum and condensation, steam enters condensing container 13 inside by pipeline, then, freezes on condensing container inside, accelerates concentrated.In the time that the volume of water in reactor 15 reaches 1L, close vacuum pump valve 19, will add NaHSO
3,
125the water sample of I tracer agent and carrier iodine, by charging aperture 36 injecting reactors 15, is then closed the valve on charging aperture 36, and adding a certain amount of concentration according to Production requirement by charging aperture 36 is the HNO of 6mol/L
3, fully stir and evenly mix, adjust pH value to≤2, in discharging opening 37 places of reactor 15 bottoms PH detection paper.Open vacuum pump valve 19, making in reactor 15 is vacuum, opens CCl is housed
4the valve of reagent bottle 17, CCl
4extractant in automatic injecting reactor 15, meanwhile, adds a certain amount of NaNO by charging aperture 36 under atmospheric effect
2, stir speed (S.S.) is transferred at a high speed, stirring in extraction process, open the valve of charging aperture 36, allow the gas of generation of extraction process discharge, then leave standstill, leave standstill 2-3 minute and wait for separatory, there is pink in lower floor, then emits, and continues to add CCl
4extract again.
In whole leaching process, adopt vacuum, condensation extracting, under vacuum state, water sample extracting is concentrated, avoided the destruction of the hotness material in water sample, owing to constantly stirring again in concentration process, add the specific surface area of flood, greatly accelerated concentration process, shorten the sample preparation time.Due to CCl
4than water weight, in reactor lower part, to mix comparatively fully and extraction efficiency in order to obtain, stirrer bottom adopts single shaft double helix paddle 162, and top adopts double leaf blade 163.Double helix paddle 162 rotary courses produce vertical flowing from bottom to top, by the CCl of bottom
4upwards carry, laterally fully mix and contact with aqueous phase substance, installed a double leaf blade 163 on top additional, strengthen horizontal CCl
4with mixing of aqueous phase substance, strengthen and mix, the efficiency of extraction.Adopt screw thread that put-put 164 is connected with central shaft 161, for convenience detach and cleaning, the extraction of mechanization, has avoided personnel to be connected to for a long time malicious CCl
4, concentrated and extraction is carried out simultaneously in a reactor, has accelerated experiment speed, simplifies experimental procedure, saves manpower.
After above-mentioned extraction is complete, in the time carrying out batch sample processing, for fear of memory effect, after sample preparation is complete, need to clean fully reactor, due to the special structure of reactor 15, can not effectively clear up some dead angles, in order to address this problem, the cleaning brush of reactor design 15.Take off stirrer 16, load onto telescopic cleaning device, realize the softened state at inside reactor, larger contact reactor inside, can effectively clean when High Rotation Speed.As shown in Figure 3, cleaning device is intersected and is symmetrically formed quadrilateral structure between two by pole 1, pole 2 32, pole 3 33 and pole 4 34, all tie points place all adopts and is articulated and connected, form multiple pin joints 35, central shaft 161 passes two pin joints 35 along quadrilateral diagonal line, hairbrush 3 is looped around the periphery of quadrilateral structure, and the bottom of central shaft 161 is provided with horizontal hairbrush near reactor 15 discharging opening 37 places, the convenient discharging opening 37 that cleans.Central shaft 161 is divided into two-section, one is truncated into screwed son 21, and another is truncated into the female 2 coordinating with it, a son 21 overhead female 2 are built-in, when central shaft 161 rotates sub 21 extension and contraction control bar that drives female 2 bottoms, under the effect of centrifugal force, realize the softened state in reactor 15 inside simultaneously.Above-mentioned according to the flexible principle of umbrella, hairbrush 3 struts in reactor 15 inside, because hairbrush 3 poles adopt plastics, there is certain plasticity, can fit with reactor 15 inwalls to greatest extent, because cleaning device is the device shape design according to reactor 15, can effectively clear up dead angle.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
