Description
Technical field
The utility model relates to a kind of water sample filtering device, is a kind of vacuum core Suction filtration device specifically.
Background technology
Will filter water sample before every biochemical indicator in analysis water-like, object is the solid particulate matter in removing water sample, can protect analytical instrument, and convenient mensuration can filter the content of state component, and the water sample good stability simultaneously after filter, is beneficial to preservation.The core filtration unit principle of current filtration water sample pours water sample in the open filter bowl of wide-mouth, recycling vacuum pump is bled the negative pressure caused in filter flask, thus making water sample by millipore filtration and core filtration unit, in water, solid particulate matter is stayed on filter membrane, thus reaches the object of filtration.But there is following defect in above-mentioned filtered water sampling device in actually operating: filter bowl volume is less, and pouring water sample into toward filter bowl when single water sample is more wastes time and energy; When water sample poured into by filter bowl, inevitably have water sample trickle down, impact analysis precision; Below filter bowl back of the body body, solid particulate matter in turning point meeting accumulated water, needs to rinse, comparatively bothers.These defective effects filter the working efficiency of water sample, reduce water sample analysis precision, thus need a kind of device of better filtration water sample to solve these problems.
Summary of the invention
For the problems referred to above, the utility model provides a kind of vacuum core Suction filtration device, and the negative pressure extracting water sample utilizing vacuum pump to cause carries out suction filtration.
The technical scheme that the utility model provides is as follows: a kind of vacuum core Suction filtration device, comprises closed filter bowl, iron fixture, millipore filtration, core filtration unit, filter flask, pipe connecting, vacuum pump line one, vacuum pump one, vacuum pump line two, vacuum pump two and these parts of water sample bottle.It is characterized in that, be connected below the closed filter bowl of this device with above core filtration unit, solid particulate matter etc. in middle placement filtering with microporous membrane water, closed filter bowl and the iron fixture of core filtration unit are fixed.Be connected with filter flask below core filtration unit.Connect water sample to be filtered with pipe connecting above closed filter bowl, perforate on the right side of it, connect vacuum pump one by vacuum pump line one.Perforate on the right side of core filtration unit, connects vacuum pump two by vacuum pump line two.
Do not communicate with air during above-mentioned closed filter bowl work, lateral opening hole is connected with vacuum pump two by vacuum pump line two, to be bled the negative pressure caused in closed filter bowl, thus absorption water sample enters filter bowl by vacuum pump.
Above-mentioned core filtration unit connects vacuum pump one by vacuum pump line one, and during work, core filtration unit and get along well air airtight with between filter flask communicates.
The power of above-mentioned vacuum pump one is greater than the power of vacuum pump two, and namely the rate of air sucked in required per second of vacuum pump one is greater than the rate of air sucked in required per second of vacuum pump two.
Below above-mentioned closed filter bowl with core filtration unit above connection place millipore filtration, and to fix with iron fixture.
Be level and smooth curvic structure below above-mentioned closed filter bowl.
Compared with prior art, the utility model has simple to operate, reduces water sample waste, efficiency advantages of higher.
Accompanying drawing explanation
Details of the present utility model and using method is further illustrated below in conjunction with accompanying drawing.
Accompanying drawing is structural representation of the present utility model.
In figure: the closed filter bowl of 1-, the iron fixture of 2-, 3-millipore filtration, 4-core filtration unit, 5-filter flask, 6-pipe connecting, 7-vacuum pump line one, 8-vacuum pump one, 9-vacuum pump line two, 10-vacuum pump two and 11-water sample bottle.
Embodiment
In the drawings, pass into water sample to be filtered by pipe connecting 6 above closed filter bowl 1, perforate on the right side of filter bowl, connected the vacuum pump 2 10 of smaller power by vacuum pump pipe connecting 29.Below closed filter bowl 1, place millipore filtration 3 above core filtration unit 4, fix, communicate below core filtration unit 4 with filter flask 5 with iron fixture 2, on the right side of it, perforate connects the vacuum pump 1 of relatively high power by vacuum pump pipe connecting 1.
During work, first open vacuum pump 2 10, closed filter bowl 1 inner air pressure reduces, and due to normal atmosphere and action of gravity, the water sample in water sample bottle 11 is entered in closed filter bowl 1 by pipe connecting 6.Now open vacuum pump 1, more powerful due to vacuum 1, the communicate air pressure of part of core filtration unit 4 and filter flask 5 can be less than air pressure in closed filter bowl 1, thus make water sample flow in the filter flask 5 of below by millipore filtration 3, core filtration unit 4, remaining solid particulate matter is stayed on millipore filtration 3, reaches filtration object.After having filtered water sample, first close vacuum pump 2 10, in formula filter bowl 1 to be closed, water all flows to after in filter flask 5 and closes vacuum pump 1 again.
