Specific embodiment
For a better understanding of the present invention, with reference to the accompanying drawing, embodiment is described in detail.It should be understood that the present embodiment is only used
In illustrating the present invention, and cannot limit the scope of the invention.
Unless otherwise indicated, technological means used by the present embodiment is ordinary skill in the art means.
Referring to Fig.1~4, the porous filter includes the filtrate collection portion of four filtration fractions above and bottommost
Point；The filtration fraction from morphology upper end to lower end successively include it is detachable, be tightly connected it is with a scale trapezoidal vertical
Section injection port 1, multilayer round pie filter plate 2, integrally manufactured filter 3, longitudinal collection conduit 4, the circle of the injection port 1
Bottom surface size is just fitted close with the upper bottom surface of the filter plate 2, for Sheng amount water sample and pushes down the filter of the filter plate 2
Film.The 2 outsourcing glass annulus 21 of filter plate, in the whole circumference of the annulus 21, upper surface is provided in one or more
Female aperture 22, lower surface are being provided with pillar 23 with 22 corresponding position of aperture, and pillar 23 can be just chimeric with aperture 22, when
When filter plate 2 is two layers or two layers or more, the pillar 23 of upper level filter plate 2 is just inserted into the aperture 22 of lower layer's filter plate 2, just
It is fixed when filter plate 2 is superimposed and uses；Particular filter material 24 is inlayed inside the filter plate 2 to penetrate water sample.The mistake
Filter plate 2 can selective stacking quantity as needed.The filter 3 divides for top 31 and lower part 32, the top 31 and the filtering
2 structure of plate identical only no pillar 23, the lower part 32 are divided inside and outside two layers, and internal layer is that funnel-form is connect with the top 31
Collect filtered water sample, longitudinal collection conduit 4 of outer layer being close to plays fixed and sealing function, outer layer side wall be provided with very
The connected lateral aspirating hole 33 of sky pump, entire filter is integrally manufactured, except filter plate external seal is extremely strong.In longitudinal collection conduit
It is provided with leakage fluid dram 5 and longitudinal collection conduit valve 41 on 4, is provided with leakage fluid dram valve 42, the longitudinal direction on the leakage fluid dram 5
The height of collection conduit valve 41 in the vertical direction is slightly above the leakage fluid dram 5, and is closing longitudinal collection conduit valve
When door 41, inclined surface (as shown in Figure 4) is formed between the longitudinal direction collection conduit valve 41 and the leakage fluid dram 5, to guarantee to close
The filtrate flowed down in longitudinal collection conduit 4 when closing longitudinal collection conduit valve 41 and opening the leakage fluid dram valve 42
It is discharged via leakage fluid dram 5；The filtrate collection part includes the oblique collecting pipe being connected with 4 lower end of longitudinal collection conduit
Road 6, oblique 6 left end of collection conduit is slightly above right end, and right end pipeline is that arc is downward, to guarantee all filtrates collected
The arc pipe lowest part of collection conduit right end can be converged to, liquid collection opening 51, the oblique collection conduit 6 is arranged in lowest part
Other than communicating with longitudinal collection conduit 4 of four filtration fractions and being communicated with the outside world by the liquid collection opening 51, remaining
Part does not communicate with the outside world, and liquid collection opening valve 43 is provided on the liquid collection opening 51, and the oblique collection conduit 6 is used for from each
The liquid that longitudinal collection conduit 4 is discharged is collected, mixing, is discharged, such as required product is gained liquid shape after two kinds of liquid filterings
At mixing liquid, the process of the mixing can complete directly in lateral collection pipeline 6, then by the discharge of liquid collection opening 51, receive
Collection.
When working using the present invention, liquid to be filtered turbidity is looked first at, turbidity is gone with regard to first carrying out prefilter greatly
Except biggish impurity and silt, then filter 3 is inserted on longitudinal collecting pipe 4, it is ensured that the two joint place is closely connected to guarantee
Filter quality, it is ensured that joint place is dry to guarantee that device is detachable, if fitted between there are liquid, in the effect of external pressure
Under it is extremely difficult separated, install after close all valves and by filter 3 lateral aspirating hole 33 and external device (ED) vacuum pump
It is connected.The superposition quantity of filter plate 2 is selected as needed and the filter membrane in suitable aperture, a filter plate 2 are placed on filter plate 2
On can only place a filter membrane, ensure that filter membrane is completely covered by the round particular filter material in 2 center of filter plate when placing filter membrane
24, the concave aperture 22 of 3 upper surface of filter is embedded in the pillar 23 of another 2 lower surface of filter plate later, pushes down filter membrane, if
Only need filter 3 that can then directly be pressed with injection port 1, when pressing is careful not to that filter membrane is made to break away, and breakking away will lead to portion
Divide water sample that can not filter, filtering failure, such as if operator needs to obtain small-sized, miniature, three grades of superminiature float
The placement of ascending sequence from bottom to top can be pressed for the filter membrane in corresponding aperture by swimming plant, in this way, a filter membrane topmost
There is the phytoplankton of small-sized grade, intermediate one layer of filter membrane only has the phytoplankton of miniature grade, and a bottom filter membrane is only super
The miniature grade plant that swims, if filter membrane breaks away, then will lead on miniature and superminiature filter membrane can have swimming for small-sized grade
Plant, small-sized grade filter membrane fail to obtain all grade phytoplanktons, i.e. filtering failure.If only needing to obtain big Mr. Yu
The phytoplankton of a grade does not need filter plate 2 then, corresponding filter membrane is directly placed on 3 top of filter, because of filter
The only no pillar 23 identical as 2 structure of filter plate of top 31.After errorless to above-mentioned each link inspection, it is first shut off all
Valve measures liquid obtained by liquid to be filtered or prefilter according to required volume, then slowly topples over the liquid of measurement
It into injection port 1, is careful not to splash out liquid, liquid filters products therefrom inaccuracy if splashing out.Open vacuum pump, device
Air pressure inside reduces, and the liquid in injection port 1 flows successively through filter plate 2 and each filter plate under the action of gravity and air pressure
Filter membrane on 2, filtrate is collected by the funnel shaped internal layer in filter lower part 32 and is discharged in longitudinal collection conduit 4, at this point, can be according to need
Opening or closing longitudinal collection conduit valve 41 is discharged to filtrate in oblique collection conduit 6 or via 5 discharger of leakage fluid dram
Outside, if longitudinal collection conduit valve 41 and liquid collection opening valve 43 are opened, leakage fluid dram valve 42 closes liquid and enters oblique collection
Pipeline 6 is discharged after mixing with filtered liquid in other longitudinal collection conduits 4 by liquid collection opening 51, if longitudinal collection conduit valve
41 close, leakage fluid dram valve 42 open then liquid by 5 discharge line of leakage fluid dram.To guarantee device leakproofness, drain needs to wait liquid
Body just can be with after all filtering is completed.
