The filter is formed by clamping and fixedly connecting the three filter cups from the top down by the fixed clamps; filter membranes in different hole diameters are arranged in the middle; the sand core funnel and the liquid collection bottle are arranged at the lower part; the filter membranes are convenient to replace; a water sample is filtered by the filter membranes in the different hole diameters via the filter cups, and finally collected in the liquid collection bottle; the filter realizes synchronous filter treatment in the different hole diameters for the same water sample; the working efficiency is improved; the sample loss is reduced; and an experimental error is greatly decreased.
Description
Technical field
The utility model relates to the marine ecology studying technological domain, relates in particular to a kind of multilayer film changeable filter, can realize that the synchronous filtering of same water sample different pore size is processed.
Background technology
In marine ecology research, marine field investigation is for guaranteeing the representativeness of experimental result, the classifications such as the investigation erect-position usually arranged, water intaking water layer are more, the seawater sample quantity of corresponding acquisition is also just very many, the suction filtration process of seawater sample is the first step of sample pretreatment normally, therefore, the quite very long work often of the suction filtration process in laboratory.Ageing for the seawater sample that guarantees to obtain, seawater sample will start suction filtration after taking back laboratory usually immediately, and because investigation labour intensity in sea own is just very high, with working continuously to often causing very large puzzlement on staff's body and mind of a collection of staff.
The suction filtration of seawater sample mainly completes by the suction filtration system be comprised of filter, tube connector, vavuum pump etc. at present.In the processing procedure of a plurality of samples, what extensively adopt at present is various multichannel filtration systems, mainly comprise that the filter holder of being furnished with independent by-pass valve control realizes, when can realizing a plurality of water sample sample, this method processes, improved operating efficiency, shorten the working time, but, because the water sample of this method after to each sample suction filtration realized mixed collection, therefore can only realize the once filtration of sample.In the scientific experiments such as chlorophyll grain size grading research, usually need to use filter membrane or the bolting silk in the multiple apertures such as 0.45 μ m, 2 μ m, 20 μ m, that is to say, each water sample will just can complete processing through the suction filtration more than three times.The suction filtration method adopted at present is mainly successively suction method,, after the bolting silk or filter membrane in the complete aperture of operating personnel's suction filtration, pours the water sample after suction filtration into the another one container, changes the bolting silk in another one aperture or filter membrane suction filtration again.This method complex operation, workload is large, operating personnel's logic had relatively high expectations, and frequent loss volume of water sample very easily in the process of falling the water sampling, and then experimental result is impacted.
The utility model content
For above-mentioned defect, the utility model provides a kind of multilayer film changeable filter, can realize that the synchronous filtering of same water sample different pore size is processed, and increases work efficiency, and reduces the loss of sample size, reduces experimental error.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of multilayer film changeable filter, this filter is by both ends open the upper filter cup that communicates, middle filter cup and lower filter cup are connected in sequence from top to bottom, upper filter cup, be provided with bolting silk in middle filter cup and lower filter cup, the aperture of bolting silk reduces gradually from upper and little, between upper filter cup and middle filter cup, the filter membrane pad is set, between middle filter cup and lower filter cup, lower filter membrane pad is set, connect funnel and liquid-collecting bottle under lower filter cup, described upper filter cup, middle filter cup, lower filter cup, fold fixed engagement by being arranged on the outer geometrical clamp of filter cup between the adjacent component of funnel four parts.
Further, on the tubule of described funnel lower end, rubber stopper is set, connector is in the bottleneck of liquid-collecting bottle.
Further, described funnel is sand core funnel.
Further, described upper filter cup bottleneck is wide-mouth, and the both ends open of the bottle Di Kou of described upper filter cup, middle filter cup and lower filter cup is for closing up, and its diameter is less than the diameter of wide-mouth.
Filter of the present utility model, gripped and be formed by connecting by geometrical clamp from top to bottom by three filter cups, centre arranges the filter membrane of different pore size, lower sand core funnel and the liquid-collecting bottle of arranging, water sample is the membrane filtration through different pore size by filter cup, finally in liquid-collecting bottle, collects.This filter has been realized the synchronous filtering processing of same water sample different pore size, and operating efficiency is improved, and the sample loss reduces, and experimental error reduces greatly.

The specific embodiment
Below in conjunction with specific embodiment, the utility model is further described.
As shown in Figure 1, multilayer film changeable filter of the present utility model, this filter is by both ends open the upper filter cup 1 that communicates, middle filter cup 2 and lower filter cup 3 are connected in sequence from top to bottom, upper filter cup 1, be provided with bolting silk in middle filter cup 2 and lower filter cup 3, the aperture of bolting silk reduces gradually from upper and little, between upper filter cup 1 and middle filter cup 2, filter membrane pad 4 is set, between middle filter cup 2 and lower filter cup 3, lower filter membrane pad 5 is set, lower filter cup connects funnel 6 and liquid-collecting bottle 7 for 3 times, described upper filter cup 1, middle filter cup 2, lower filter cup 3, fold fixed engagement by being arranged on the outer geometrical clamp 8 of filter cup between funnel 6 four parts adjacent components.
On the tubule of described funnel 6 lower ends, rubber stopper 9 is set, connector is in the bottleneck of liquid-collecting bottle 7.
Described funnel 6 is sand core funnel.
The bottleneck of described upper filter cup 1 is wide-mouth, and the both ends open of bottle Di Kou, middle filter cup 2 and the lower filter cup 3 of described upper filter cup 1 is for closing up, and its diameter is less than the diameter of wide-mouth.
The water sample gathered is the membrane filtration through different pore size by filter cup, finally in liquid-collecting bottle 7, collects, thereby has realized that the synchronous filtering of same water sample different pore size processes, and operating efficiency is improved, and the sample loss reduces, and experimental error reduces greatly.
The above is only a kind of embodiment of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model know-why; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
