Description
Technical field
The utility model is related to a kind of Buchner funnel.
Background technology
Buchner funnel is a kind of ceramic instrument used in laboratory, also useful plastic production, for using vacuum or
Negative pressure suction is filtered.Inventor is generally believed for Nobel chemistry Prize winner's Edward's Joachim Büchner in 1907, thing
In reality, Buchner funnel is invented by chemist Ernst B ü chner.Oblate tubular is shaped as, has been opened on cylinder bottom surface a lot of little
Hole.The long and narrow tubular outlet of one, lower company.When use, funnel is injected Bu Shi by general first filter paper on the pad of cylinder bottom surface
Flask upper opening by sealing joint (such as use rubber ring).The side port of Bu Shi beakers connects extract system.Then it is intended to separate
Solid, liquid mixture pour top into, liquid component is drawn into beaker under negative pressure effect, and solid stays in top.Conventional
Crystallization is extracted in Experiment of Organic Chemistry.After the completion of the filtration of such case, up can also be washed off with a small amount of neat solvent
The impurity of crystal surface.
Existing Buchner funnel is using front needing to prepare pumping and filtering device, such as vavuum pump, the bottle,suction, (sealing of Buchner funnel support
Circle), vacuum tube (rubber tube), filter paper, Buchner funnel etc..First filter paper is soaked with water, taken out, make filter paper abut against hopper base
End, can prevent thing to be filtered from missing.Pour filtrate into, operate machine and take out, somewhat can stir, only remaining filtering solids.Directly
Connect with common funnel, after sticking filter paper, it is not all right to connect aspiration pump and carry out suction strainer (replacement Buchner funnel).Because funnel four
Wall is close at filter paper, and negative pressure suction strainer does not work to which.Pressure difference is produced only under funnel at drift angle.Due to this mouthful larger, and
Only one of which mouth, it is easy to rupture.
Existing filtered on buchner funnel effect is bad at present, not there is antiskid function, installs inconvenient.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of good filtration effect, with antiskid function, easy for installation
Buchner funnel.
For solving the above problems, the utility model is adopted the following technical scheme that：
A kind of Buchner funnel, including funnel housing, outer tube body and interior tube body, the outer tube body is located at funnel housing bottom,
The outer tube body is integrally formed with funnel housing, and said inner tube body is located in outer tube body, and the funnel housing central section was provided with
Filter plate, is provided with through hole in the filter, and the through hole is provided with nonwoven layer and work in being equally spaced on the filter
Property layer of charcoal, the filter, nonwoven layer and active carbon layer are arranged successively from bottom to up, and the outer tube body bottom is provided with frosted
Portion, described outer tube body one end are provided with radiating tube, the radiating tube and outer tube body by integral forming.
Preferably, the through-hole diameter is 1-5mm, keep filtrate good by property.
Preferably, said inner tube body is connected with funnel housing, facilitate the discharge of filtrate.
Preferably, the tapered setting in said inner tube body bottom, holding filtrate can be in Accelerating Removal in inner tube body.
Preferably, described radiating tube one end is arranged in screw thread, keep radiating tube easy for installation.
Preferably, the active carbon layer thickness is 4mm, keep filter efficiency high.
The beneficial effects of the utility model are：The active carbon layer of setting keeps good filtration effect；The nonwoven layer energy of setting
Enough prevent active carbon layer from revealing, keep easy to maintenance；The frosted portion of the outer tube body bottom of setting has antiskid function, keeps installing
Convenient；The radiating tube of setting can be passed through coolant, and effectively interior tube body is cooled down.
Description of the drawings
Fig. 1 is a kind of structure chart of Buchner funnel of the utility model.
Specific embodiment
As shown in figure 1, a kind of Buchner funnel, including funnel housing 1, outer tube body 2 and interior tube body 3, the outer tube body 2 is located at
1 bottom of funnel housing, the outer tube body 2 are integrally formed with funnel housing 1, and said inner tube body 3 is located in outer tube body 2, the leakage
Filter 4 is installed in the middle part of bucket housing 1, through hole 5 in the filter 4, is provided with, the through hole 5 is in be equally spaced, the mistake
Be provided with nonwoven layer 6 and active carbon layer 7 on filter plate 4, the filter 4, nonwoven layer 6 and active carbon layer 7 successively from down to
Upper setting, 2 bottom of the outer tube body are provided with frosted portion 8, and 2 one end of the outer tube body is provided with radiating tube 9, the radiating tube 9
It is integrally formed with outer tube body 2.
5 a diameter of 1-5mm of the through hole, keeps filtrate good by property.
Said inner tube body 3 is connected with funnel housing 1, facilitates the discharge of filtrate.
The tapered setting in 3 bottom of said inner tube body, holding filtrate can be in Accelerating Removal in interior tube body 3.
9 one end of the radiating tube is arranged in screw thread, keeps radiating tube 9 easy for installation.
7 thickness of the active carbon layer is 4mm, keeps filter efficiency high.
The beneficial effects of the utility model are：The active carbon layer of setting keeps good filtration effect；The nonwoven layer energy of setting
Enough prevent active carbon layer from revealing, keep easy to maintenance；The frosted portion of the outer tube body bottom of setting has antiskid function, keeps installing
Convenient；The radiating tube of setting can be passed through coolant, and effectively interior tube body is cooled down.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model do not limit to
In this, any change or replacement that expects without creative work should all be covered within protection domain of the present utility model.
