The water sample suction filtration device capable of automatically discharging liquid is simple in structure, reasonable in design and convenient to clean; the liquid inside the suction filtration flask can be automatically discharged in time by the liquid discharging pipe on the side wall of the bottom of the suction filtration flask; the flow rate of the discharged liquid can be controlled by adjusting the cock; and the water sample suction filtration device is convenient to operate, time-saving and labor-saving and has practical significance for suction filtration of large-volume filtrate.
Description
Technical field
The utility model relates to a kind of laboratory apparatus, specifically, but is a kind of water sample suction filtration device of automatic drain.
Background technology
The suction filtration device is laboratory a kind of laboratory apparatus commonly used, and bottle,suction of the prior art needs the stopper that connects on the bottle,suction is extracted after suction filtration is finished, and just can pour out the liquid of bottle,suction the inside.Because the finite capacity of bottle,suction, when the water sample of suction filtration is more, for preventing that liquid is inhaled into vavuum pump, need in time the liquid of bottle,suction the inside to be poured out, need in the operating process once or for several times interrupt operation, so increase work load to the operator, and increased the probability that damages vavuum pump.
Therefore, but need a kind of water sample suction filtration device of automatic drain.
The utility model content
The purpose of this utility model is, but a kind of water sample suction filtration device of automatic drain is provided, can be in the suction filtration process in time, automatically liquid is discharged.
For achieving the above object, the technical scheme taked of the utility model is:
But a kind of water sample suction filtration device of automatic drain, comprise bottle,suction, funnel, perforated rubber stopper, rubber tube and vavuum pump, described funnel inserts in the bottle,suction by described perforated rubber stopper, described rubber tube one end is connected with the air exhaust nozzle of bottle,suction, the other end is connected with described vavuum pump, the sidewall of described bottle,suction bottom is provided with discharging tube, and discharging tube is equipped with cock at the mouth of pipe place of bottle,suction outside.
Described discharging tube and bottle,suction are one-body molded.
Described funnel is sand core funnel or Buchner funnel.
The utility model advantage is: but the water sample suction filtration device of this automatic drain is simple in structure, reasonable in design, easy to clean, discharging tube on the sidewall of bottle,suction bottom can be in time, automatically the liquid in the bottle,suction is discharged, can control the flow velocity of discharging liquid by regulating cock, easy to operate, time saving and energy saving, to suction filtration substantially the filtrate of accumulated amount have more practical meaning.
Description of drawings
But accompanying drawing 1 is the structural representation of the water sample suction filtration device of the utility model automatic drain.
The Reference numeral and the part that relate in the accompanying drawing are as follows:
1. bottle,suction 11. bottle,suction bottlenecks
12. discharging tube 13. cocks
14. air exhaust nozzle 2. funnels
3. perforated rubber stopper 4. rubber tubes
5. vavuum pump
The specific embodiment
Below in conjunction with embodiment and with reference to accompanying drawing the utility model is further described.
Please refer to Fig. 1, but Fig. 1 is the structural representation of the water sample suction filtration device of a kind of automatic drain of the utility model.This suction filtration device comprises bottle,suction 1, funnel 2, perforated rubber stopper 3, rubber tube 4 and vavuum pump 5.Funnel 2 inserts in the bottle,suction bottleneck 11 of bottle,suction 1 by perforated rubber stopper 3, and rubber tube 4 one ends are connected with the air exhaust nozzle 14 of bottle,suction 1, and the other end is connected with vavuum pump 5.The sidewall of bottle,suction 1 bottom is provided with discharging tube 12, and discharging tube 12 is equipped with cock 13 at the mouth of pipe place of bottle,suction 1 outside.
Before the suction filtration operation, bottle,suction 1, funnel 2, perforated rubber stopper 3, rubber tube 4 and vavuum pump 5 are assembled cut-out tap 13.The liquid that needs filter is poured in the funnel 2, opened vavuum pump 5 beginning suction filtration work.When the filtrate liquid level in the bottle,suction 1 exceed discharging tube 12 go out open height the time, open cock 13, filtrate is namely flowed out from discharging tube 12 automatically by self gravitation, bottle,suction 1 interior filtrate liquid level can not reach the height of air exhaust nozzle 14, more can not be inhaled in the vavuum pump.Can control the flow velocity of filtrate in the discharging tube 12 by regulating cock 13, avoid bottle,suction 1 interior filtrate liquid level to be lower than the open height that of discharging tube 12.In the suction filtration process, need not pull up the rubber tube 4 that connects air exhaust nozzle 14, also need not close vavuum pump 5, until all liq is drawn in the bottle,suction 1 fully, pull up again the rubber tube 4 that connects air exhaust nozzle 14 from funnel, close vavuum pump 5.Filtrate is flowed out from discharging tube 12 automatically, being lower than the filtrate that discharging tube 12 goes out open height and can it being flowed out fully by the bottle,suction 1 that tilts a little of bottle,suction 1 the inside.
Need to prove, discharging tube 12 can be one-body molded with bottle,suction 1, and funnel 2 can be sand core funnel, also can be Buchner funnel, perhaps the funnel that is used for filtration of other type.
But the water sample suction filtration device of the utility model automatic drain is simple in structure, reasonable in design, easy to clean, discharging tube on the sidewall of bottle,suction bottom can be in time, automatically the liquid in the bottle,suction is discharged, can control the flow velocity of discharging liquid by regulating cock, easy to operate, time saving and energy saving, to suction filtration substantially the filtrate of accumulated amount have more practical meaning.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement and replenish, these improvement and replenish and also should be considered as protection domain of the present utility model.
