It is merely to illustrate the utility model, and the scope of the utility model cannot be limited.
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 successively includes ladder with a scale that is detachable, being tightly connected from morphology upper end to lower end
Shape longitudal section injection port 1, multilayer round pie filter plate 2, integrally manufactured filter 3, longitudinal collection conduit 4, the injection port 1
Round 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 plate 2
Filter membrane.The 2 outsourcing glass annulus 21 of filter plate, in the whole circumference of the annulus 21, upper surface is provided with one or more
A concave aperture 22, lower surface are being provided with pillar 23 with 22 corresponding position of aperture, and pillar 23 can be just embedding with aperture 22
It closes, 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
In, it is fixed when being superimposed and use convenient for filter plate 2；Particular filter material 24 is inlayed inside the filter plate 2 to penetrate water sample.Institute
Stating filter plate 2 can selective stacking quantity as needed.The filter 3 divides for top 31 and lower part 32, the top 31 with it is described
2 structure of filter plate identical only no pillar 23, the lower part 32 are divided inside and outside two layers, and internal layer is funnel-form and the top 31
Filtered water sample is collected in connection, and outer layer abutting longitudinal collection conduit 4 plays fixed and sealing function, outer layer side wall and is provided with
The lateral aspirating hole 33 being connected with vacuum pump, entire filter is integrally manufactured, except filter plate external seal is extremely strong.In longitudinal collection
It is provided with leakage fluid dram 5 and longitudinal collection conduit valve 41 on pipeline 4, is provided with leakage fluid dram valve 42 on the leakage fluid dram 5, it is described
The height of longitudinal collection conduit valve 41 in the vertical direction is slightly above the leakage fluid dram 5, and is closing longitudinal collecting pipe
When road valve 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 protect
What card flowed down in longitudinal collection conduit 4 when closing longitudinal collection conduit valve 41 and opening the leakage fluid dram valve 42
Filtrate is discharged via leakage fluid dram 5；The filtrate collection part includes the oblique receipts being connected with 4 lower end of longitudinal collection conduit
Collect pipeline 6, oblique 6 left end of collection conduit is slightly above right end, and right end pipeline is that arc is downward, all to guarantee to collect
Filtrate can converge to the arc pipe lowest part of collection conduit right end, and liquid collection opening 51, the oblique collection is arranged in lowest part
Pipeline 6 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,
Rest part does not communicate with the outside world, and is provided with liquid collection opening valve 43 on the liquid collection opening 51, the oblique collection conduit 6 be used for from
The liquid that each longitudinal direction collection conduit 4 is discharged is collected, mixing, is discharged, such as required product is gained liquid after two kinds of liquid filterings
The mixing liquid that body is formed, the process of the mixing can be completed directly in lateral collection pipeline 6, then pass through 51 row of liquid collection opening
Out, it collects.
When being worked using the utility model, liquid to be filtered turbidity is looked first at, turbidity is greatly with regard to first carrying out preposition mistake
Filter off remove biggish impurity and silt, then filter 3 is inserted on longitudinal collecting pipe 4, it is ensured that the two joint place closely connect with
Guarantee to filter quality, it is ensured that joint place is dry to guarantee that device is detachable, if fitted between there are liquid, in external pressure
It is extremely difficult separated under effect, install after close all valves and by filter 3 lateral aspirating hole 33 and external device (ED) it is true
Sky pump is connected.The superposition quantity of filter plate 2 is selected as needed and the filter membrane in suitable aperture, a mistake are placed on filter plate 2
A filter membrane can only be placed on filter plate 2, ensure that filter membrane is completely covered by the round particular filter in 2 center of filter plate when placing filter membrane
Material 24 is embedded in the concave aperture 22 of 3 upper surface of filter with the pillar 23 of another 2 lower surface of filter plate later, pushes down filter
Film, if only need filter 3 can if directly pressed with injection port 1, when pressing, is careful not to that filter membrane is made to break away, and sideslip can lead
Cause part water sample that can not filter, filtering failure, such as if operator needs to obtain small-sized, miniature, three grades of superminiature
Phytoplankton the filter membrane in corresponding aperture can be pressed the placement of ascending sequence from bottom to top, in this way, a filter topmost
Film only has the phytoplankton of small-sized grade, and intermediate one layer of filter membrane only has the phytoplankton of miniature grade, and a bottom filter membrane is only
There is superminiature to swim grade plant, if filter membrane breaks away, then will lead on miniature and superminiature filter membrane can have small-sized grade
Phytoplankton, small-sized grade filter membrane fail to obtain all grade phytoplanktons, i.e. filtering failure.If only needing to obtain big
Filter plate 2 is not needed then in the phytoplankton of some grade, and corresponding filter membrane is directly placed on 3 top of filter, because
The only no pillar 23 identical as 2 structure of filter plate of filter top 31.After errorless to above-mentioned each link inspection, it is first shut off
All valves measure liquid obtained by liquid to be filtered or prefilter according to required volume, then slowly by the liquid of measurement
It is poured onto injection port 1, is careful not to splash out liquid, liquid filters products therefrom inaccuracy if splashing out.Vacuum pump is opened,
Device air pressure inside reduces, and the liquid in injection port 1 flows successively through filter plate 2 and each mistake under the action of gravity and air pressure
Filter membrane on filter plate 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 root
Filtrate is set to be discharged in oblique collection conduit 6 or be discharged via leakage fluid dram 5 according to needing to open or close longitudinal collection conduit valve 41
Outside device, if longitudinal collection conduit valve 41 and liquid collection opening valve 43 are opened, the closing liquid of leakage fluid dram valve 42 enters oblique
Collection conduit 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
Equal liquid just can be with after all filtering is completed.
