Description
Technical field
The utility model is related to the experimental provision of processing sample, and especially one kind can obtain grade stratified sediment sample
Experimental provision.
Background technology
Deposit is not only the remittance of pollutant, or pollutant source.The physical chemistry of water/sediment interface and biological work
With the environmental index (such as oxidation-reduction potential), microbial bacteria group structure caused in surface deposit vertical direction in gradient
Variation tendency.Also exactly because the graded characteristic of these indexs affects pollutant and cuts down work on hole-transport direction
With.Therefore Biological indicators, physical and chemical index and the variation characteristic of contamination index are most important in the vertical direction of research deposit top layer.
And the collection layering of deposit is also the key link in this research.The method for obtaining stratified sediment sample existing at present
It is to gather column shaped deposit using columnar sampler, then is bottom-up released surface deposit with push rod, then on demand
Carry out layering collection.The problem of this method is that the major function of this sampler is sampling, is layered thicker, unsuitable grade
The collection of stratified sediment.
Utility model content
The utility model provides a kind of experimental provision for obtaining grade stratified sediment sample, and the device is applied to
The variation characteristic of contamination index, physical and chemical index, Biological indicators etc. on hole-transport direction is studied, surface deposit point is solved
The technical barrier of layer collection is conducive in the vertical direction of research deposit top layer there is provided the method that grade deposit is gathered
Variation characteristic.
In order to solve the above-mentioned technical problem, the utility model is achieved through the following technical solutions：
A kind of experimental provision for obtaining grade stratified sediment sample, including cylindrical drum, hassock piece and shim liner, circle
Column casing is hollow, and inside sets round pie hassock piece and shim liner with identical area, and hassock piece is located above shim liner,
The locus on edge forms deposit room, the lower surface of shim liner and the lower edge of cylindrical drum in the upper surface of hassock piece to cylindrical drum
Holding is flushed, and hassock piece and shim liner match with cylindrical drum, between the internal diameter of the outer and cylindrical drum of hassock piece and shim liner
The gap that width is 0.25-0.5mm is formed, a diameter of 95-105mm of cylindrical drum is highly 50-70mm, the thickness of barrel
For 5-10mm, the thickness of hassock piece is 2-8mm, and quantity is 1-10 pieces, and the thickness of shim liner is 1-5mm, and quantity is 1-10 pieces.
Moreover, the thickness of described hassock piece is preferably 4-6mm, quantity is preferably 1-5 pieces.
Moreover, the thickness of described hassock piece is preferably 1-3mm, quantity is preferably 1-5 pieces.
Compared with prior art, the beneficial effects of the utility model are：
Cylindrical drum and the repeatable utilization of pad, and have the advantages that easy processing cost is low；During sampling, pad causes deposit
Position is moved up, and the deposit for protruding cylindrical drum is accurately collected, and is realized the longitudinal millimeter stage layered of deposit, is effectively solved burning
The problem of cup experiment deposit is difficult to gather, is difficult layering；And the material of the device uses lucite, is easy to experimentation
In observation and use.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view planar structure schematic diagram of the present utility model.
Wherein 1 is cylindrical drum, and 2 be hassock piece, and 3 be shim liner, and 4 be deposit room.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, a kind of experimental provision for obtaining grade stratified sediment sample, including cylindrical drum 1,
Hassock piece 2 and shim liner 3, cylindrical drum is hollow, and inside sets round pie hassock piece and shim liner with identical area, hassock
Piece is located above shim liner, and the locus on edge forms deposit room on the upper surface of hassock piece to cylindrical drum, shim liner
The lower edge of lower surface and cylindrical drum keeps flushing, and hassock piece and shim liner match with cylindrical drum, hassock piece and shim liner outside
Along the gap that width is 0.25mm is formed between the internal diameter of cylindrical drum, a diameter of 100mm of cylindrical drum is highly 60mm,
The thickness of barrel is 8mm, and the thickness of hassock piece is 5mm, and quantity is 8, and the thickness of shim liner is 2mm, and quantity is 2.
A kind of application method for the experimental provision for obtaining grade stratified sediment sample is to follow the steps below：
Step 1：Sediment sample is put into deposit room into cylindrical drum, paves to form deposit layer；Make deposit
The upper surface of layer is flushed with cylindrical drum top edge；
Step 2：N piece shim liners are put into by the lower end of cylindrical drum, hassock piece thereon, shim liner and deposit layer is upward
Push away, until the shim liner of bottom is inserted in cylindrical drum, and deposit layer is boosted accordingly apart from (n piece shim liners
Thickness)；
Step 3：The deposit of protrusion is swept using upper surface of the thin slice instrument along cylindrical drum, is moved in culture dish；
Step 4：Repeat step 3 and step 4, until the hierarchical operations of deposit are completed, the sample of layering is standby to enter
The follow-up experiment of row.
To the stratified sampling of deposit for Biological indicators, physical and chemical index and pollution in the vertical direction of research deposit top layer
The variation characteristic of index is most important, and the present apparatus is caused by way of adding pad to cylindrical drum bottom on deposition object location
Move, the deposit for protruding cylindrical drum is accurately collected, realize the longitudinal millimeter stage layered of deposit, realize the layering to deposit
The improvement of sampling experimental operating technology.
The utility model is described in detail above, but the content is only preferred embodiment of the present utility model,
It is not to be regarded as being used to limit practical range of the present utility model.All equivalent changes made according to present utility model application scope with
