Description
Technical field
The utility model belongs to sampling thief field, is mainly used in gathering metallic ion in water body and soil, and especially a kind of multi-joint dress heavy metal is dynamic Simple sampler easily.
Background technology
1994, by a British scientist Davison and diffusion thin film technique (DiffusiveGradients in Thin-films that sky is invented, DGT), can more authentic and valid simulation soil dynamic course of reaction, and performance model can estimate the kinetic parameter of soil dynamic process, thus the importance of soil dynamic process can be assessed better.DGT device based on DGT technological development is made up of filtering membrane, diffusion barrier and adsorption film and the plastic wrapper of fixing this trilamellar membrane.Wherein filtering membrane is mainly used to protection diffusion barrier and adsorption film, avoids the particle in environment to be measured to enter DGT device; Diffusion barrier can allow the ion free diffusing of solution state; Adsorption film experimentally object can select different absorption materials.Along with the development of science and technology, DGT material is also being updated and is being upgraded, and if liquid is in conjunction with the use of phase, the different diffusion phase of thickness and the combination etc. in conjunction with phase, makes traditional support can not meet the demand of practical application.The advantages such as the support opening the DGT device of vast and boundless teacher invention is made up of base and enclosing cover, has simple structure, small volume, easy to carry, but can not be used for placing liquid in conjunction with phase.
In the patent that the patent No. is (201120009011.8) disclosed the passive sampling apparatus of metallic ion " in water environment or the soil pore water ", overcoat is made up of sampling container and base plate, sampling container and base plate are fixed by screw, there is the hole of cylindrical shape sampling container inside, the right cylinder of band circular cone cavity is placed in empty, although this invention solves liquid and combines application on DGT, this overcoat also exist remove and install complexity, volume greatly, the deficiency that solid bond can not be used to be on good terms.
The patent No. be (201320066419.8) " metallic ion biologically effective state sampling thief overcoat of multi-usage adjustable thickness " its by plastic ring supporter, plastics circle inner core, plastics rounded body enclosing cover and two sealing rubber rings form, although this invention solves liquid and combines mutually and the application of solid bond on DGT, also there is making DGT sampling thief complexity in this overcoat, the problem such as inconvenience, easily leakage and equipment cost height preserved by sampling thief.
The mechanism of said apparatus is all comparatively complicated, and cost of manufacture is relatively high, and carries with operability low, haves much room for improvement.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and provide one to make simply, facilitate easy-to-use, lower-cost multi-joint dress heavy metal easily dynamic Simple sampler, capsule shape design, greatly improves the use simplification of sampling thief.
The technical scheme that the utility model realizes object is as follows:
A kind of multi-joint dress heavy metal is dynamic Simple sampler easily, comprise base and coverlay, base upper surface is pasted in coverlay sealing, base integrated injection molding forms multiple hollow cylindrical recessed groove, the sidewall of recessed groove is coaxially integrally shaped with radial extension step trough, extension step trough coboundary one connects plane on base, under-filled sorbing material layer in recessed groove, diffusing material layer is filled on the top of sorbing material, the height of diffusing material layer equals recessed groove height, protective seam is filled in extension step trough, protective seam contacts with diffusing material layer, the height of protective seam is equal with extension step trough, base is fixedly mounted with a seal ring piece around extension step trough, inner edge and the cylindrical depression groove of seal ring piece are isometrical, and axially align.
And, described extension step trough height 0.13mm, cylindrical depression groove 0.8-1.6mm.
The beneficial effects of the utility model are:
The sampling thief that the application provides can as required quick Fabrication, each layer thickness can flexible configuration, can according to the metallic ion diffusion phase of different-thickness with in conjunction with phase, select different-thickness supporter, manufacturing process is simple and easy to do, do not need main equipment, manufacturing cost is low.
The sealing property of the sampling thief that the utility model provides is strong, applies when can sample in water body and sediment, and usable range is wide, and its capsule shape design simultaneously, greatly improves the use simplification of sampling thief.
