Abstract
The utility model relates to a combined-type suction filtration device which comprises a vacuum pig tail, a liquid collection bottle, a funnel, a perforated rubber plug, a rubber tube and a vacuum pump, wherein the upper end opening of the vacuum pig tail is connected with the funnel through the perforated rubber plug; the lower end opening of the vacuum pig tail is connected with the liquid collection bottle; a vacuum pig tail suction nozzle is arranged on one side surface of the vacuum pig tail, and is connected with the vacuum pump through the rubber tube. The combined-type suction filtration device is simple in structure, reasonable in design and convenient to operate; the liquid collection bottle can be replaced according to the volume of filtrate and the requirements of follow-up operation to be suitable for all suction filtration operation. A suction filtration bottle is replaced by the combination of the liquid collection bottle and the vacuum pig tail, so that the suction filtration device is easy to clean, most predominantly, waste of the filtrate during a transition process is avoided fundamentally. Therefore, the combined-type suction filtration device has particularly practical significance for suction filtration operation of small-volume filtrate or high-concentration filtrate.
Description
Technical field
The utility model relates to a kind of laboratory apparatus, specifically, is a kind of Combined type suction filtering device.
Background technology
Suction filtration device is the conventional a kind of laboratory apparatus in laboratory, bottle,suction of the prior art is bled and liquid collecting one, therefore need the liquid filtering after suction filtration completes, while carrying out subsequent operation, filtrate must be transferred to other container from bottle,suction, so filtrate will become waste in transfer process, the filtrate of corpusculum accumulated amount and high concentration particularly, in practical operation, in order to reduce the loss, must repeatedly use solvent wash, so to operator, increase work load.
Summary of the invention
The purpose of this utility model is to provide a kind of Combined type suction filtering device, and this device can fundamentally be avoided the waste of filtrate in transfer process when suction filtration, and flow process simplifies the operation.
The technical scheme that the utility model adopts is: a kind of Combined type suction filtering device, comprise vacuum tap, liquid-collecting bottle, funnel, perforated rubber stopper, rubber tube, vavuum pump, be characterized in: vacuum tap upper port is connected with funnel by perforated rubber stopper, lower port is connected with liquid-collecting bottle, vacuum tap side is provided with vacuum tap air exhaust nozzle, and vacuum tap air exhaust nozzle is connected with vavuum pump by rubber tube.
Funnel is sand core funnel or Buchner funnel.Vacuum tap lower port outer wall and liquid-collecting bottle bottleneck inwall are equipped with frosted layer.Vacuum tap lower port overall diameter and liquid-collecting bottle bottleneck interior diameter measure-alike, its size range is 0 ~ 1000 mm.Liquid-collecting bottle is conical flask.
The beneficial effects of the utility model are: this Combined type suction filtering apparatus structure is simple, reasonable in design, easy to operate, liquid-collecting bottle can be changed as required according to the requirement of filtrate volume amount and subsequent operation, be applicable to all suction filtration operations, bottle,suction be divided into the combination of liquid-collecting bottle and vacuum tap, be easy to the cleaning of suction filtration device, more mainly fundamentally avoided the waste of filtrate in transfer process, particularly the suction filtration operation of corpusculum accumulated amount filtrate and high concentration filtrate has been had to more practical meaning.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is elaborated.
As shown in Figure 1, a kind of Combined type suction filtering device, comprises vacuum tap 1, liquid-collecting bottle 2, funnel 3, perforated rubber stopper 4, rubber tube 5 and vavuum pump 6.
Funnel 3 is connected with vacuum tap 1 upper end smooth mouth surface 7 by perforated rubber stopper 4, and liquid-collecting bottle 2 is connected with vacuum tap 1 lower end frosted mouth 8, and rubber tube 5 one end are connected with the vacuum tap air exhaust nozzle 9 of vacuum tap 1, and one end is connected with vavuum pump 6.
Funnel 3 is sand core funnel or Buchner funnel.Vacuum tap 1 lower port outer wall and liquid-collecting bottle bottleneck inwall are equipped with frosted layer.Vacuum tap 1 lower port overall diameter and liquid-collecting bottle 2 bottleneck interior diameters measure-alike, its size range is 0 ~ 1000 mm.Liquid-collecting bottle 2 is conical flasks.
The utility model connects the liquid-collecting bottle of select 2, vacuum tap 1, funnel 3, perforated rubber stopper 4, rubber tube 5 and vavuum pump 6 before use, and the liquid that needs are filtered is poured in funnel 3, opens vavuum pump 6, starts suction filtration.After suction filtration completes, must first rubber tube and the air exhaust nozzle of vacuum tap be separated, close vavuum pump, then liquid-collecting bottle and vacuum tap are separated, the related filtrate of liquid-collecting bottle can be carried out subsequent operation.If once cannot complete, select another identical liquid-collecting bottle, repeat aforesaid operations.
The utility model is Combined type suction filtering device, simple in structure, reasonable in design, easy to operate, liquid-collecting bottle can be changed as required according to the requirement of filtrate volume amount and subsequent operation, is applicable to all suction filtration operations, bottle,suction is divided into the combination of liquid-collecting bottle and vacuum tap, be easy to the cleaning of suction filtration device, more mainly fundamentally avoided the waste of filtrate in transfer process, particularly the suction filtration operation of corpusculum accumulated amount filtrate and high concentration filtrate is had to more practical meaning.
The above is only preferred embodiment of the present utility model; should be understood that for those skilled in the art; do not departing under the prerequisite of the utility model principle, can also do some improvement and supplement, these improvement and supplement and all should be considered as protection domain of the present utility model.
