Abstract
Description
Technical field
The utility model relates to a kind of filter, particularly relates to a kind of Suction filtration device of prevented filtrate contamination of use for laboratory.
Background technology
At present, usually use the Separation of Solid and Liquid that Buchner funnel and bottle,suction device realize test specimen in the laboratory such as chemical industry, biology, and then respectively analytical test is carried out to solid and liquid.Suction filtration process is: extracted out by the air in bottle,suction by vavuum pump, and make bottle,suction inside form vacuum, and then sucked in bottle,suction by the liquid in funnel, solid is then blocked by filter paper, realizes Separation of Solid and Liquid.At the end of suction filtration, because still there is negative pressure in bottle,suction, often the oil in vavuum pump or suction filtration machine or water can be sucked in bottle,suction, contaminated liquid sample, makes the analytical test result of liquid inaccurate.In addition, during due to sample that suction filtration is different, need bottle,suction cleaned and changed frequently, operation inconvenience, adds burden to testing crew.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of Suction filtration device preventing filtrate contamination.
Its technical scheme is: a kind of Suction filtration device preventing filtrate contamination, comprise bottle and funnel, it is characterized in that: the filler tube of described funnel is connected and sealed by rubber stopper and bottle, be provided with suspension arrangement bottom described filler tube, sampling bottle hangs on the bottom of filler tube by suspension arrangement; The side, lower end of described bottle is provided with discharging tube, and described discharging tube is provided with draining valve; The side, upper end of described bottle is provided with suction filtering tube, described suction filtering tube has suction filtration mouth and blow vent, and described suction filtration mouth is provided with gas one-way valve, and described gas one-way valve only allows gas to discharge, and described blow vent is provided with gas valve.
The bore of described sampling bottle is less than the bore of bottle opening, is greater than the bore bottom filler tube.
The utility model compared with prior art, have the following advantages: structure is simple, reasonable in design, effectively prevent the oil in vavuum pump or suction filtration machine or water from entering contaminated liquid sample in bottle,suction, the fluid sample collected in sample bottle can take off directly to be preserved and for analyzing, avoid and run off because fluid sample shifts the sample caused, especially the situation that sampling requirement is high to liquid component content is few is adapted to, do not need to rinse bottle,suction, sample bottle is taken off the flushing just directly can carrying out solid sample, reduce the burden of operating personnel.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Drawing illustrates: 1. bottle 2. funnel 3. rubber stopper 4. filler tube 5. suspension arrangement 6. sampling bottle 7. discharging tube 8. draining valve 9. suction filtering tube 10. suction filtration mouth 11. gas one-way valve 12. blow vent 13. gas valve.
Detailed description of the invention
With reference to accompanying drawing 1, a kind of Suction filtration device preventing filtrate contamination, comprise bottle 1 and funnel 2, it is characterized in that: the filler tube 4 of described funnel 2 is connected and sealed by rubber stopper 3 and bottle 1, suspension arrangement 5 is provided with bottom described filler tube 4, sampling bottle 6 hangs on the bottom of filler tube 4 by suspension arrangement 5, and the bore of described sampling bottle 6 is less than the bore of bottle 1 mouthful, is greater than the bore bottom filler tube 4; The side, lower end of described bottle 1 is provided with discharging tube 7, and described discharging tube 7 is provided with draining valve 8; The side, upper end of described bottle 1 is provided with suction filtering tube 9, described suction filtering tube 9 has suction filtration mouth 10 and blow vent 12, and described suction filtration mouth 10 is provided with gas one-way valve 11, and described gas one-way valve 11 allows gas to discharge, and described blow vent 12 is provided with gas valve 13.
During use, hung on by sampling bottle 6 bottom filler tube 4, insert in bottle 1 by funnel 2 by rubber stopper 3, suction filtration mouth 10 is connected with vavuum pump or suction filtration machine by rubber tube, and draining valve 8 and gas valve 13 are all in closed condition.In funnel 2, place filter paper, in funnel 2, pour sample to be separated into.When vacuum pump work, air in bottle 1 is drawn out of by suction filtration mouth 10, make to form vacuum state in bottle 1, liquid in funnel 2 passes through filter paper under suction function, flow in sampling bottle 6 along filler tube 4, be not sealing bottom filler tube 4 and between sampling bottle 6, when sampling bottle 6 is filled, fluid sample can spill in bottle 1.In separation process be separated and terminate after, the gas one-way valve 11 that suction filtration mouth 10 place installs can effectively prevent the oil in vavuum pump or suction filtration machine and steam from entering in bottle 1, avoids fluid sample contaminated, ensures the accuracy of result of laboratory test.After liquid sample collection completes, first close vavuum pump or suction filtration machine, then funnel 2 is taken off on bottle 1, the sampling bottle 6 on suspension arrangement 5 is taken off and seals and deposits, so that follow-up analytical test.
After sampling bottle 6 takes out, then funnel 2 is inserted in bottle 1, clear water is poured into and is equipped with in the funnel 2 of solid sample, start vavuum pump or suction filtration machine, carry out the flushing to solid sample.When the liquid in bottle is too much, closes vavuum pump or suction filtration machine, open the gas valve 13 on blow vent 12 and the draining valve 8 on discharging tube 7 successively, washing lotion can be discharged.
