Description
Technical field
It the utility model is related to a kind of test bottle, more particularly to a kind of experiment safety flack.
Background technology
Vacuum extractor is often used in experiment of synthetic chemistry, for example in polyester synthesis experiment, polycondensation phase needs
Alcohol that will be unnecessary in discharge system in time is, it is necessary to which vacuum extractor constructs vacuum environment.Using existing safety flack and vavuum pump
With reference to after using a period of time, many liquid can be entered in the pump housing, these liquid can have a strong impact on the practical longevity of vavuum pump
Life, if corrosive liquids influences more very, in addition can also cause pump housing oil spout, vacuum declines.Existing safety flack is made
It is actual to pump housing protective effect and little for a kind of suck-back device, meanwhile, sold safety flack bottle is smaller on the market, air inlet
Manage it is oversize, typically also do not have liquid collecting function.
Utility model content
A kind of the defects of the utility model is in order to overcome prior art, there is provided use for laboratory anti-suck safety flack.
Use for laboratory anti-suck safety flack, including safety flack bottle, the side of the safety flack bottle are provided with an outlet
Conduit, the top of the safety flack bottle are provided with an air induction conduit, and one end of the air induction conduit extends vertically into safety
In bottle bottle, the other end is arranged at outside the safety flack bottle, and the air induction conduit stretched into safety flack bottle is in hook-shaped, and end
Raise up setting.
Preferably, the air induction conduit stretched into safety flack bottle is L-shaped, and end raises up and sets formation to raise up section, described
The section that raises up is vertically arranged with L-shaped junction.
Preferably, it is highly 0.4cm -0.6cm that the section that raises up, which raises up,.
Preferably, the bottom of the air induction conduit stretched into safety flack bottle is higher than the outlet side of the outtake tube.
Preferably, the bottom of the air induction conduit stretched into safety flack bottle is higher than the outlet side 2cm- of the outtake tube
5cm。
Preferably, the air induction conduit direction that raises up is oppositely arranged with outgassing direction.
Preferably, the safety flack bottle is in column structure, and lower end diameter is straight more than the upper end of the safety flack bottle
Footpath.
Preferably, vavuum pump is connected with by pipeline on the outtake tube, the air induction conduit is connected with by pipeline
Reactor.
Preferably, the pipeline on the outtake tube and the pipeline on the air induction conduit are flexible duct.
Preferably, connected between the safety flack bottle and air induction conduit and outtake tube using glass solder.
The beneficial effects of the utility model are embodied in：Safety flack can be very good to play a part of anti-suck, while can also
Liquid as far as possible in collection conduit, so as to extend the service life of vavuum pump.
Brief description of the drawings
Fig. 1：Structural representation of the present utility model.
Embodiment
The utility model discloses a kind of use for laboratory anti-suck safety flack, with reference to shown in Fig. 1, including safety flack bottle 6,
The side of the safety flack bottle 6 is provided with an outtake tube 4, and the top of the safety flack bottle is provided with an air induction conduit 2,
Vavuum pump is connected with by outlet pipe 5 on the outtake tube 4, the air induction conduit 2 is connected with reaction by admission line 1
Kettle.In order to preferably install and portability, outlet pipe 5 and admission line 1 use flexible duct.
The safety flack bottle 6 and air induction conduit 4 and outtake tube 2 are all made of glass, and use glass between connecting
Glass is welded to connect integrally.Glass solder ensure that the seal in bottle.
One end of the air induction conduit 2 is extended vertically into safety flack bottle, and the other end is arranged at the safety flack bottle
In vitro.The air induction conduit stretched into safety flack bottle is in hook-shaped, and end raises up setting.And hook-shaped bottom is away from safety flack bottle bottom
The distance in portion is more than the gas outlet of outtake tube to the cm-5cm of safety flack bottle body bottom 2.
Specifically, the air induction conduit stretched into safety flack bottle is L-shaped, and end raises up and sets formation to raise up section, described
The section that raises up is vertically arranged with L-shaped junction.The section that raises up ensure that the function of anti-suck, and it is highly 0.4 that the section that raises up, which raises up,
Cm-0.6cm, it is typically preferable using 0.5cm.The air induction conduit direction that raises up is oppositely arranged with outgassing direction, due to air inlet side
To opposite with outlet, the condensation that there can be greater room into the gas in bottle is ensure that, can sufficiently be condensed.
To ensure that safety flack bottle can absorb enough solution, and be advantageous to the condensation of gas, the safety flack bottle 6
In column structure, and lower end diameter is more than the upper end diameter of the safety flack bottle, and safety flack bottom of bottle is flat.Safety flack bottle
Lower end diameter is larger, also make it that its standing is more firm.
The utility model still has a variety of specific embodiments.All institutes formed using equivalent substitution or equivalent transformation
Have technical scheme, all fall within the requires of the utility model protection within the scope of.
