Description
Technical field
The utility model is related to laboratory equipment field, specifically, being related specifically to a kind of Suction filtration device.
Background technology
The experiment of conventional ballast water is acquisition microorganisms in water, need to first filter the impurity in removal water sample.Normal practice be by
In water sample injection Suction filtration device, the water sample of primary about 400 milliliters of filtering.In practical operation, how much the impurity of water sample can not be intuitive
Observation, accumulation of the impurity in filter membrane cause follow-up water body to filter inefficiency, expend the time, it usually needs replaces filter membrane.
When replacing filter membrane, it be easy to cause water sample and splashes；When shifting water sample, microorganism is easily attached on container, and is easily caused to water sample
Secondary pollution.
Utility model content
The purpose of this utility model is that for deficiency of the prior art, a kind of Suction filtration device is provided, it can be more quick
Carry out filter, can one man operation complete, and can preferably protect when replacing filter membrane the integrality of water sample, toppling over water
The loss and pollution of water sample will not be caused during sample.
Following technical scheme may be used to realize in the technical issues of the utility model solves：
A kind of Suction filtration device, it is described including the filter assemblies for being used to place the container of water sample and being used cooperatively with container
Filter assemblies include filter cup, and the bottom of filter cup is connected by connector with the water inlet of container；
The opening for pouring into water sample is offered at the top of the filter cup, opening is with the cup lid for sealing, the mistake
The bottom of filter bowl is connected by the top of geometrical clamp and connector and fixed, and is equipped in the junction of the filter cup and connector
Filter membrane；
Valve is equipped in the connector, valve is used to control the opening and closing of the runner of filter assemblies, the connector bottom
Portion is connected by the water inlet of detachable structure and container and fixed.
Further, the cup lid is mounted on the opening of filter cup by helicitic texture, and helicitic texture includes being located at
The external screw thread of filter bowl opening and the internal thread on cup lid medial surface.
Further, the detachable structure includes being arranged on connector bottom end face and the magnetic of container head end face connects
Fitting.
Compared with prior art, the beneficial effects of the utility model are as follows：
1) it realizes the film that changes during filtering, reduces and filter the time, improve and filter efficiency.
2) integrality of effective protection water sample ensures to filter result accuracy.
Description of the drawings
Fig. 1 is the structure diagram of Suction filtration device described in the utility model.
Fig. 2 is the sectional view of magnetic coupling described in the utility model.
Specific embodiment
To be easy to understand technical means, creative features, achievable purpose and effectiveness of the utility model, below
With reference to specific embodiment, the utility model is expanded on further.
Referring to Fig. 1 and Fig. 2, a kind of Suction filtration device described in the utility model, the container 1 including being used to place water sample, with
And the filter assemblies 2 being used cooperatively with container 1, the filter assemblies 2 include filter cup 21, the bottom of filter cup 21 passes through connection
Part 22 is connected with the water inlet of container 1；
21 top of filter cup offers the opening for pouring into water sample, and opening is with the cup lid 211 for sealing, institute
The bottom for stating filter cup 21 connect fixation by geometrical clamp 4 with the top of connector 22, in the filter cup 21 and connector 22
Junction filter membrane is installed；
Valve 221 is equipped in the connector 22, valve 221 is used to control the opening and closing of the runner of filter assemblies 2, described
22 bottom of connector connect fixation by detachable structure with the water inlet of container 1.
The cup lid 211 is mounted on the opening of filter cup 21 by helicitic texture, and helicitic texture includes being located at filter cup
The external screw thread of 21 openings and the internal thread on 211 medial surface of cup lid.
The detachable structure includes the magnetic coupling 3 for being arranged on 1 top end face of 22 bottom end face of connector and container.
The course of work of the utility model is as follows：
1) first by Fig. 1 is looked for install Suction filtration device；
2) it and then by water sample by filter cup injects, when suction filtration speed becomes extremely slow, starts to change the operation of film water conservation.
3) cup lid is tightened, and screws the valve in connector, finally beat the magnetic coupling of connector and bottle mouth position
It opens.
4) top half removed is upside down on experimental bench, opens the clip of filter cup mouth, membrane operations are changed in completion.
5) it will put at film on geometrical clamp folder, top half will be closed with lower half portion by magnetic coupling.
6) cup lid of filtering rim of a cup is removed, glass valve is opened, continues to filter, is terminated until entirely changing film water conservation task.
The basic principle of the utility model and main feature and the advantages of the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
