Abstract
The utility model provides a kind of vent cabinet for preventing from condensing mixing liquid refluence pollution, a kind of to prevent from condensing the vent cabinet that mixing liquid flows backwards pollution, including：Cabinet, upper end inside the cabinet is gas sampling chamber, it is vented airduct, the exhaust, exhaust airduct has ring-type septal leaflet, and ring-type septal leaflet collecting tank annular in shape together with being formed between being vented the inner tubal wall of airduct, the side of the collecting tank offers a through hole discharged for waste liquid, the through hole connects one end of a waste liquid drainage tube, the other end connection waste liquid collection vessel of the waste liquid drainage tube.The utility model is to avoid discharged waste gas condensation or the waste liquid condensed into from flowing backward at distribution experiment operation platform, it is ensured that test not contaminated and experimenter safe.
Description
Technical field
The utility model is related to experiment safeguard field, more particularly to a kind of prevents that condensing mixing liquid flows backwards pollution
Vent cabinet.
Background technology
Exhaust duct for the vent cabinet used in experiment generally all with discharge waste gas, but the operation carried out in vent cabinet
It is much the experiment for discharging sour gas, alkaline gas or other harmful dusts to have, and these gases or impurity are in discharge process
If meeting wet weather or cold snap, harmful waste liquid will be easily condensed on the inwall of exhaust duct, foregoing this
If a little harmful waste liquids flow backwards and dropped onto in vent cabinet in operating table surface, ongoing experiment can be polluted, meanwhile,
Also injury can be produced to experimenter.
Utility model content
In order to solve the above-mentioned technical problem, disclosed in the utility model it is a kind of prevent condense mixing liquid flow backwards pollution
Vent cabinet, to avoid discharged waste gas condensation or the waste liquid condensed into from flowing backward at distribution experiment operation platform, it is ensured that experiment is not
Contaminated and experimenter is safe.The technical solution of the utility model is implemented：
It is a kind of to prevent from condensing the vent cabinet that mixing liquid flows backwards pollution, including：
Upper end inside cabinet, the cabinet is gas sampling chamber,
Be vented airduct, the exhaust, exhaust airduct there is ring-type septal leaflet, the ring-type septal leaflet with exhaust airduct inner tubal wall it
Between form one of collecting tank annular in shape, the side of the collecting tank offers a through hole discharged for waste liquid, and the through hole connects
One end of a logical waste liquid drainage tube, the other end connection waste liquid collection vessel of the waste liquid drainage tube.
Preferably, being provided with the waste liquid drainage tube is used to have the pump that waste liquid detaches collecting tank.
Preferably, the quantity of the ring-type septal leaflet for it is multiple and along exhaust airduct bearing of trend arrange, multiple ring-types every
The quantity of the collecting tank formed between valve and exhaust airduct is multiple；The side of each collecting tank offers one and discharged for waste liquid
Through hole, each through hole connects a waste liquid drainage tube, and all waste liquid drainage tubes conflux and are communicated in waste liquid collection vessel.
Preferably, the cross sectional shape of the collecting tank is inverted trapezoidal or circular arc.
Implementing the beneficial effects of the utility model is：
1st, with ring-type septal leaflet, with exhaust airduct formation collecting tank, the harmful waste liquid of backflow can be drained, it is ensured that experiment
Not contaminated and experimenter is safe.
2nd, it is simple and reliable for structure, it is easy to implement, while without prejudice to flue gas is discharged, above-mentioned accident can be avoided to send out again
It is raw.
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art

Upper end inside cabinet, the cabinet is gas sampling chamber,
Be vented airduct, the exhaust, exhaust airduct there is ring-type septal leaflet, the ring-type septal leaflet with exhaust airduct inner tubal wall it
Between form one of collecting tank annular in shape, the side of the collecting tank offers a through hole discharged for waste liquid, and the through hole connects
One end of a logical waste liquid drainage tube, the other end connection waste liquid collection vessel of the waste liquid drainage tube.
Being provided with as a kind of preferred scheme, in the waste liquid drainage tube is used to have the pump that waste liquid detaches collecting tank.
As a kind of preferred scheme, the quantity of the ring-type septal leaflet is bearing of trend row multiple and along exhaust airduct
Row, the quantity of the collecting tank formed between multiple ring-type septal leaflets and exhaust airduct is multiple；The side of each collecting tank is opened up
There is a through hole discharged for waste liquid, each through hole connects a waste liquid drainage tube, and all waste liquid drainage tubes conflux and are communicated in useless
Liquid collection vessel.
As a kind of preferred scheme, the cross sectional shape of the collecting tank is inverted trapezoidal or circular arc.
It is pointed out that preferred embodiment of the present utility model is the foregoing is only, not to limit this reality
With new, all within spirit of the present utility model and principle, any modification, equivalent substitution and improvements made etc. all should be included
Within protection domain of the present utility model.
