Description
Technical field
The utility model relates to a kind of quick filter.
Technical background
Chlorophyll-a is to estimate one of water body eutrophication degree very important index, when surveying chlorophyll-a, general experimenter buys assembly assembly units such as bottle,suction, Buchner funnel and vavuum pump to finish, gas leak phenomenon is general, filtration time is longer, and because chlorophyll is seen photo-labile, the time, long more decomposition was many more, so filter for a long time, influence conventional efficient and experimental result greatly.
At present, the relevance filtering device price of Shi Yonging is higher on the market, the rate of filtration is slower, and for this reason, design has been processed this and overlapped quick filter, this device is processing and installation easily, and cost is low, and simultaneously, speed improves greatly during filtration, not only improve conventional efficient, and improved the degree of accuracy and the reliability of experimental result.
Summary of the invention
The purpose of this utility model is to provide the quick filter that a kind of cost is lower, easy to operate, can more obviously raise the efficiency and test accuracy.
The quick filter that the utility model proposes is made up of measuring container 1, filter tunnel 2, pvc pipe 3, vacuum meter 5, control valve 6, vacuum tank 7, atmospheric valve 8, vavuum pump 9 and base plate 10.Wherein, filter tunnel 2 is made up of suction filtration threeway 4, funnel upper strata parts 12, funnel lower part 13, antidrip pipe fitting 14 and funnel ground parts 15, funnel upper strata parts 12 are positioned at funnel lower part 13 tops, and it is fixedly connected by screw, antidrip pipe fitting 14 is positioned at funnel lower part 13, and place below, funnel lower part 13 tops, funnel ground parts 15 are positioned at funnel lower part 13 belows, and funnel lower part 13 1 sides are provided with suction filtration threeway 4; Measuring container 1 is fixed in base plate 10 tops by fixed screw 11, and filter tunnel 2 is positioned at measuring container 1 top, and funnel ground parts 15 are placed in measuring container 1 top drilling position, filter tunnel 2 and measuring container 1 is screwed be one; Vacuum tank 7 is fixed in base plate 10 tops, vacuum meter 5 and control valve 6 are equipped with in vacuum tank 7 tops, the bottom is provided with atmospheric valve 8, and the suction filtration threeway 4 of filter tunnel 2 connects the pvc pipe joint 16 that is positioned at vacuum tank 7 one sides by pvc pipe 3, and vacuum tank 7 tops connect vavuum pump 9 by pvc pipe 3.
In the utility model, funnel lower part 13 tops have aperture, and the number of aperture is 4-6/cm
2, be the twice of little hole count on the conventional funnel unit are.
The course of work of the present utility model is as follows:
Filter membrane entirely is positioned over funnel lower part 13 tops, and water is wetting slightly, makes filter membrane be close to funnel lower part 13, and funnel upper strata parts 12 are in placing funnel lower part 13 tops, and tightens upper and lower layer is become one.Let slip filter funnel 2 in measuring container 1 top, and screw.Measuring container 1, vacuum tank 7 all are fixed in base plate 10 tops.Pvc pipe 3 one ends insert suction filtration threeway 4, and the other end inserts the pvc pipe joint 16 of vacuum tank 7, and vacuum tank 7 and vavuum pump 9 also can link together by pvc pipe, make control valve 6 and atmospheric valve 8 be in closed condition.The water sample of pouring the need filtration into is opened vavuum pump 9 in filter tunnel 2, rotating regulation valve 6 is regulated vacuums to desired value (characterizing by vacuum meter 5 readings).Water sample filters and to finish, and closes vavuum pump 9, opens atmospheric valve 8, and the volume of water sample takes out the filter membrane in the filter tunnel 2 in the record measuring container 1, and this filter membrane is that to survey in the water body chlorophyll a content used.The filtration time of a water sample shortens greatly, only is the part of the suction filtration device filtration time of routine.
The beneficial effects of the utility model are, have avoided that similar experimental provision is easily broken, gas leakage is serious, it is not enough easily inadequately to use, and that this experimental provision has is easy to assembly, sealing is tight, filtering surface big, filter efficiency is than characteristics such as height.
