Description
Technical field
The utility model is related to a kind of device for being used to filter large volume water sample, specifically a kind of to be used for substantially
The auxiliary frame and auxiliary device of product scene water sample filtering, belong to ocean water quality process field.
Background technology
With the development that China's ocean development and marine protection work, marine environmental monitoring and investigation work are increasingly frequent,
And the water sample that marine monitoring inquiry agency is adopted generally requires to be filtered and dosing (fixative) is stored refrigerated afterwards, to ensure
The validity of sample data.
The filtering of water sample is general according to National Standard of the People's Republic of China (GB17378.3- in marine environment investigation
2007) method in is carried out, and is measured certain volume water sample into sand core funnel, using Vacuum filtration device, is passed through 0.45 micron
Fibrous filter membrane filtered (wherein heavy metal water sample need to adjust pH value to less than 2), the water sample after all filterings need to refrigerate guarantor
Deposit, final transport to laboratory is analyzed.Filter in GB17378.3-2007 is adopted always during marine monitoring works
Traditional water sample filter, general sand core funnel volume is generally used, bottom is without fixation in an experiment in 0.5-1L
Device (is used) in land laboratory.
Laboratory on the important step that sample filtering works as marine environment investigation sample pre-treatments, ocean monitoring ship
Often the very first time filters to field sample, for the water sample of some routine monitoring indexs, such as nutrient salts (inorganic nitrogen,
Reactive phosphate), heavy metal (copper, lead, zinc, cadmium etc.), chlorophyll a etc., often only need to filter 0.1-1L or so water quality sample
Product, you can meet refrigeration and preserve the minimum volume requirement of sample., can in the water sample filter process of routine monitoring index
So that the volume of water sample number of required sample is well disposably poured into the funnel of filter with measurer amount, it is to be filtered be about at the end of plus
Enter the filter process that the medicines such as fixative just complete such assay.But working as needs the specific of high-volume measure in monitoring
When water sample volume is larger needed for index, such as the measure (polycyclic aromatic hydrocarbon, benzene homologues) of some organic indexs, often
Need to filter 4-10L seawater sample and add the medicines such as fixative, this kind of monitoring index sample volume exceeds well over core often
The capacity (generally 0.5-1L) of funnel, it is impossible to the water sample of required volume was just added to sand core funnel once or several times
In, and organic assay often requires that filtering terminates or adds another liquid (fixative class medicine at the end of being bordering on
Product), this just forces the scientific research personnel on ship to expend considerable time and effort and measured to carry out the volume of seawater sample, count with
Dosing.In addition, cabin where marine experimental implementation is general very narrow, space is limited, and liquid is measured using multigroup large volume measuring device
Body is natively very inconvenient, if the bulk sample of high-volume filtering simultaneously, easily causes operation chaotic and personnel wastes, and
When the sea is rough, for security consideration, or even sample filtering work can only be stopped.On the other hand, even in normal work
Under the conditions of, the funnel volume of conventional water filter be it is fixed, it is temporarily customized for different marine monitoring tasks and index
Many size large volume filters are very inconvenient and actual.To sum up, considered based on above real work situation, one kind can be with
The design and use of servicing unit for filtering large volume water sample and Automatic Dosing liquid are current marine environmental monitoring works
In work in the urgent need to.
The content of the invention
The purpose of this utility model is to provide a kind of sample pretreatment apparatus (the large volume water quality of marine monitoring field investigation
Sample filtering), specifically a kind of auxiliary frame and auxiliary device for the live water sample filtering of large volume, using this reality
The sample treatment efficiency of marine monitoring personnel can be obviously improved with the device of new offer, simplifies sample filtering flow and improves work
Make comfort level.
A kind of device for being used to filter large volume water sample, including sample filtering mechanism, automatic liquid-feeding structure and auxiliary
