Abstract

The utility model provides a suction filtration device for a laboratory, belonging to the technical field of chemical experimental equipment and solving the technical problem that filtrate enters an air extractor through an extraction opening in a suction filtration process in the prior art. The suction filtration device comprises a suction flask and a suction filtration seat, wherein the suction flask comprises a flask neck and a flask belly connected with the flask neck, the outer wall of the flask belly is provided with at least one extraction opening communicated with the flask belly, the suction filtration seat comprises a rubber plug in interference fit with the flask neck, a conduit passing through the rubber plug and a funnel communicated with the conduit and fixedly connected with the conduit, and the flask belly is also internally provided with a striker plate. Due to the design of the striker plate, the filtrate is blocked outside the extraction opening, so that the filtrate is prevented from entering the air extractor from the extraction opening, and the air extractor is protected from being corroded by the filtrate.

Description

Use for laboratory suction filtration device
Technical field
The utility model belongs to equipment of chemical industry technical field, relates to a kind of air-exhausting filtering device, especially relates to a kind of use for laboratory suction filtration device.
Background technology
Bottle,suction is a kind of vessel that often use in laboratory, mostly is glassware, and a kind of for flask has the bleeding point of a side direction at mouth of pipe place, be used for bleeding or connecting vacuum extractor.By suction filtration seat is installed on bottle,suction, just form a suction filtration device.In use, by air extractor (being generally vavuum pump) bleeding point, bleed, make the inner formation of bottle,suction vacuum, thereby the liquid on suction filtration seat is drawn in bottle,suction, and solid is blocked by the filter paper in suction filtration seat or filter member, realizes Separation of Solid and Liquid.
But existing suction filtration device in use, because bleeding point has Air Flow, filtrate can be sucked or is incorporated in bleeding point, and these filtrates finally can enter into air extractor (vavuum pump), to air extractor, can produce certain corrosiveness, thereby affect suction filtration effect.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of use for laboratory suction filtration device is provided; Solve filtrate in the existing suction filtration process of prior art and can enter into through bleeding point the technical problem of air extractor.
For achieving the above object, the utility model has adopted following technical proposal: a kind of use for laboratory suction filtration device, comprise bottle,suction and suction filtration seat, described bottle,suction comprises bottleneck and the bottle tripe being connected with bottleneck, on described bottle tripe outer wall, is provided with at least one bleeding point, and described bleeding point is communicated with bottle tripe, described suction filtration seat comprises the rubber stopper with bottleneck interference fit, the conduit that runs through rubber stopper, the funnel that is communicated with and is fixedly connected with conduit with conduit is also provided with striker plate in bottle tripe.
Described bottle,suction is conical flask.
Described striker plate is inclined to set with respect to vertical direction.
Described tilt angle alpha is 10 °-30 °.
Compared with prior art, the utility model has the advantage of: by the design of striker plate, make filtrate be blocked in bleeding point outside, thereby prevented that filtrate from entering into air extractor by bleeding point, protected air extractor by filtrate, not corroded.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model provides.
In figure, bottle 1, bottleneck 11, bottle tripe 12, bleed 13, striker plate 14, suction filtration seat 2, rubber stopper 21, conduit 22, funnel 23.
The specific embodiment
As shown in Figure 1, a kind of use for laboratory suction filtration device, comprise bottle,suction 1 and suction filtration seat 2, described bottle,suction 1 comprises bottleneck 11 and the bottle tripe 12 being connected with bottleneck 11, on described bottle tripe 12 outer walls, is provided with at least one bleeding point 13, and described bleeding point 13 is communicated with bottle tripe 12, described suction filtration seat 2 comprises the rubber stopper 21 with bottleneck 11 interference fit, the conduit 22 that runs through rubber stopper 21, the funnel 23 that is communicated with and is fixedly connected with conduit 22 with conduit 22 is also provided with striker plate 14 in bottle tripe 12.Described striker plate 14 blocks the air inlet of bleeding point 13, in the present embodiment, as a kind of preferred scheme, between striker plate 14 and the bottle wall of bottle tripe 12, seals, and striker plate 14 exists space with the bottom of bottle tripe 12, can allowing air flow.
Described bottle 1 is conical flask.Described striker plate 14 is inclined to set with respect to vertical direction; Described tilt angle alpha is 10 °-30 °.
In use, only suction filtration seat 2 need be inserted in bottleneck 11 by rubber stopper 21, can realize being fixedly connected with of suction filtration seat 2 and bottle,suction 1, bleeding point 13 is connected to vavuum pump or other air extractors, in funnel 23, add filter paper, filter paper needs to cover the port of conduit 22, then needs the filtrate of filtration can realize work toward pouring in funnel 23.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
