Background technology
The field condition collected specimens is the requisite links of work such as scientific research and environmental management, geologic examination.The greatest problem that field sampling runs into is the sample retention problem: in order to obtain the real conditions of survey area, former state is preserved sample as far as possible.But this point is difficult to accomplish under the condition in fact in the open air: sample needs the regular hour from the collection site to the laboratory usually, and owing to the acute variation of condition, sample can change in transit.The preservation of sediment sample is difficulty especially: because sediment sample is under water for a long time; Its top layer is in weak reducing condition; Subsurface stratum and deep layer generally are in anaerobic state, collected land after because the acute variation of external condition (becomes oxygen enrichment by anaerobism; Great changes have also taken place in temperature) very big variation also taken place in its physicochemical property, result of study produced have a strong impact on.
At present still there is not special open-air sediment sampling storage box, the main way that adopts the built-in ice cube of common sampling box in the practical operation.But in the open air, ice cube is easy to melt, and a large amount of frozen water of generation can immerse sample sack, and sample is changed; And a large amount of air (the case lid switching manipulation also can be brought air into) are arranged in the case, and oxygen wherein makes anaerobism sediment generation oxidation, causes Eh (ORP), AVS important indicators such as (sour volatile sulfur compoundses) to measure.The problem that exists in addition is: the sediment columnar samples can't former state be preserved (in order to further investigate sediment character, gather columnar samples and be absolutely necessary), and is difficult to transportation.
The utility model content
The purpose of the utility model be to provide a kind of preservation effect good, be convenient for carrying, the on-the-spot former state save set of sediment simple to operate, low cost of manufacture.To solve the deficiency that above-mentioned existing apparatus exists.
A kind of sampling box of preserving sediment sample comprises the casing and the porous barrier 6 that have case lid 1, and said porous barrier 6 is divided into two chambers up and down with casing, is the sample chamber above, is icehouse below, and said icehouse is placed with ice cube.
Also be provided with air intake opening 8 and gas outlet 3 on the said box body wall, air intake opening 8 is connected with nitrogen cylinder through pipeline, and the pipeline that connects said air intake opening 8 and gas outlet 3 is equipped with valve.
Also comprise columnar samples conserving case 10 and be used for columnar samples conserving case 10 is fixed on the columnar samples dividing plate 9 in the casing that columnar samples dividing plate 9 is a porous plate, columnar samples conserving case 10 places the hole; Columnar samples conserving case 10 comprises air admission hole 12 and the venthole 13 that appearance bottle 9, bottle stopper 11 and the bottle stopper of placement cylindrical sample are provided with.The appearance bottle is shaped as right cylinder.
Said casing both sides are provided with drop handle, and cabinet shell is double-deck hollow plastic material.
The quantity of said porous barrier 6 is a plurality of.
The method of application of described sampling box comprises following concrete steps:
(1) seal case, from air intake opening 8 toward casing in logical nitrogen 1 ~ 2 min, residual air 3 is discharged from the gas outlet in the casing;
(2) put sediment sample into sample sack or columnar samples conserving case 10 rapidly, to the air admission hole 12 logical nitrogen 15 ~ 30s of sample sack or columnar samples conserving case 10, residual gas is discharged through pipeline from venthole 13;
(3) open case lid 1, sample sack or columnar samples conserving case 10 are put to casing; Cover case lid 1 rapidly, from air intake opening 8 toward casing in logical nitrogen 1 ~ 2 min.
The gas speed of nitrogen is 180 ~ 250cm in the step (1)
3/ min, the gas speed of nitrogen is 18 ~ 25cm in the step (2)
3/ min, the gas of nitrogen speed 180 ~ 250cm in the step (3)
3/ min.
The utility model is compared with existing save set, has following advantage and effect: the utility model effectively former state is preserved sample, guarantees relevant physicochemical character Data Detection accurate and effective as a result; Easy and simple to handle, cheap, easy to carry.
