Description

Quick suction filtration device
Technical field
This utility model is related to a kind of Suction filtration device, more particularly to a kind of can in line liquid Quick suction filtration device.
Background technology
In detection and analysis work, it is often necessary to carry out efficient solid-liquid separation.Sample collecting process in environmental monitoring In, referring to《The measure inductively coupled plasma mass spectrometry of HJ 700-2014 65 kinds of elements of water quality》Etc. relevant criterion, work people Multiple sampled points carry out water body sampling to member's needs and scene completes to filter in the wild.Height of the front man to filtration in-situ Imitate quick demand very urgent.
In hydrology and water conservancy field, referring to《GB 50159-1992 Code for measurement of sus pended sediment in open channels》Etc. relevant criterion, hang It is frequently necessary to carry out filter operation to obtain solid-state silt in the courses of work such as silt detection.Under this scene, sample Amount is very big, does not often reach tonne not, filters workload very huge;Staff is a kind of efficient in the urgent need to having, quickly, surely Fixed, the Suction filtration device of high degree of automation is assisting them preferably to complete to detect work.
Fig. 1 is the structure chart of traditional Suction filtration device.
Reduce pressure in bottle,suction as shown in figure 1, sucking filtration is one kind using steam extraction pump, so as to accelerated filtration reaches solid-liquid Separate the filter method of purpose.Commonly use Suction filtration device in the market and all can be similar to figure below, its operation principle is:
Vacuum pump forms negative pressure by the bleeding point on bottle,suction, in bottle,suction.In Buchner filter, liquid is made in negative pressure People is leaked to bottle,suction with lower, solid is stayed in funnel.After liquid is crowded with bottle,suction, needs first to pull out exhaust tube, make sucking filtration Bottle inside and outside air pressure balance;Buchner filter is further taken out, after pouring out bottle,suction hydrops, sucking filtration next time could be continued.This sucking filtration dress Putting mainly has this some deficiency in actually detected work:
(1) sucking filtration speed is slow.
Especially when in water sample, silt equal size is more than 2/1000ths, can slowly even sucking filtration stopping.Must change After filter paper, and re-start filtration.And this is unsatisfactory for standard《GB 50159-1992 Code for measurement of sus pended sediment in open channels》To one Secondary filtration can not change the requirement of filter paper.Therefore the sediment test gauging work in the high river of the sediment charges such as similar the Changjiang river can not be met.
(2) inconvenient operation, efficiency are low
The detection work for taking solid sample is needed for sediment test gauging is this, and liquid can not be in line.When sucking filtration starts every time, It is required for the liquid that first clears up in bottle,suction:Trachea is extracted in bleeding point, air pressure balance is made;Funnel is further taken out, bottle,suction is poured out In liquid.This obviously can not meet the filtration work that river load detects this tonnage magnitude.
(3) single sucking filtration process is often interrupted, and experiment needs are reformed
From above from the point of view of (1) and (2) two points of deficiencies, either because bottle,suction hydrops is completely also because that water sample concentration height makes Filter paper loses filtration, is required for stopping sucking filtration, discards the water sample in Buchner filter, re-starts sucking filtration test.So Work efficiency has just been had a strong impact on
(4) frequently artificial plug operation it cannot be guaranteed that air-tightness
In air pressure balance and cleaning bottle,suction, the artificial operation of liquid, often causes air-tightness bad.So as to affect to take out Filter effect.
