Description
Technical field
Laboratory glassware field is the utility model is related to, more particularly to a kind of addition funnel and is leaked using the liquid feeding
The reflux of bucket.
Background technology
During chemical operation, it usually needs build a set of reactor using glass apparatus.If add in the reactor
During volatile reagent, a whole set of reactor needs to build in fume hood in advance.Space is limited in fume hood, usually in fume hood most
Rack is fixedly mounted in inner side, and glass apparatus is fixed on installation rack by flask holder, cross clamp, geometrical clamp, uses up reactor
Amount is at the ventilating opening in fume hood.After reactor fixes, reaction raw materials are added in corresponding glass apparatus.Due to
The bottleneck of glass apparatus is smaller, is needed into glass apparatus during pouring liquid by funnel.
Reactor is fixed on installation rack, and the spacing between reactor and installation rack is smaller, and conventional funnel is back taper
Shape, upper end opening is larger, when it is positioned over the bottleneck of glass apparatus, takes up space larger, is easily interfered with installation rack,
Be inconvenient to pick and place.
Utility model content
The purpose of this utility model is to provide a kind of addition funnel, it, which has, saves space, the advantages of beneficial to fluid injection.
The above-mentioned technical purpose of the utility model technical scheme is that：A kind of addition funnel, bag
Integrally formed funnel body and filler neck are included, funnel body includes buffering side wall, and the top for buffering side wall is liquid injection port, buffers side wall
Bend inwards to form resigning portion close to one end of liquid injection port.
Preferably, resigning portion is vertical with liquid injection port end face.
Using above technical scheme, the buffering side wall of funnel body is made of two parts, and a part retains falling for conventional funnel
Pyramidal structure, another part are arranged to the resigning portion parallel with filler neck, and resigning portion is a vertical plane.Glass apparatus combines
Reactor put up after, if than narrow, the addition funnel fluid injection can be used in liquid feeding space.Due to buffering the shape of side wall
Shape is inverted cone-shaped structure, and end opening is larger thereon, it has not been convenient to is placed at small space.In use, resigning portion snug space by
Space is saved at limit, buffering side wall facilitates liquid feeding towards operator direction.
Preferably, the axis direction of the upper end of resigning portion towards funnel tilts.
Using above technical scheme, resigning portion back bending is more, liquid injection port smaller, when liquid is injected into reactor, if having
Liquid is spilt, and resigning portion can play the role of certain block.
Further, the height of resigning portion is the 3/4-4/5 of funnel height degree.
Using above technical scheme, the height of resigning portion is so set, further reduce the space shared by funnel body, side
Just it is used for the operating mode of liquid feeding narrow space.
Further, connected between funnel body and filler neck using cambered surface.
Using above technical scheme, the liquid of addition is added from the opening of funnel body, and flows into reaction by filler neck
In device.Cambered surface is set between funnel body and filler neck, is smoothly flowed down easy to fluid.
Further, the bottom of filler neck is arranged to beam ground.
Using above technical scheme, chemically react reaction bulb used and usually all carry beam ground, filler neck lower end
The beam ground in portion, convenient and reaction bulb are fitted close.Since the filler neck of conventional funnel bottom is thinner, using routine
Funnel carry out liquid feeding when, filler neck is respectively less than the bottleneck of reaction bulb, when adding volatile solvent, volatilization gas can from filler neck with
The gap location effusion of reaction bulb.And when using the addition funnel that beam ground is carried in this programme, addition funnel is tight with reaction bulb
Close fit, can reduce escaping gas effusion.
Further, it is 120-150 degree to buffer side wall with filler neck angulation.
Using above technical scheme, the angle between side wall and filler neck is buffered in the scope, and liquid can be along slow
Side wall is rushed slowly to flow downward in reactor.
Further, the bottom of filler neck sets drainage oblique angle.
Using above technical scheme, when liquid edge buffering side wall is flowed out from filler neck lower end, work of the liquid at drainage oblique angle
Quickly flowed down with lower, addition funnel can be extracted after fluid injection, change glass stopper or rubber stopper into, seal reactor.
If filler neck lower end be not provided with drainage oblique angle, liquid from filler neck flow out when, easily formed liquid drippage, extension feed time.
The another object of the utility model is to provide a kind of reflux, during the limited space that feeds, its have save it is empty
Between the advantages of.
The above-mentioned purpose of the utility model is achieved through the following technical solutions：A kind of reflux, including it is above-mentioned
Addition funnel.
When building reflux, if liquid feeding space is relatively more limited, grafting is above-mentioned at the filling opening of reflux adds
Liquid funnel, the resigning portion of addition funnel are placed at restricted clearance, save charging space.
In conclusion the utility model has the advantages that：
Addition funnel includes buffering side wall and resigning portion, and when running into the environment of liquid feeding limited space, resigning portion is to funnel body
Inside back bending, save space.
