Description
Technical field
The utility model is related to a kind of assembly type Buchner funnel, belongs to chemical laboratory instrument field.
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, and is shaped as on oblate tubular, cylinder bottom surface having opened many apertures, lower one long and narrow tubular of company goes out
Mouthful, when use, funnel is injected Bu Shi flasks upper opening and interface is close by the general first filter paper on the pad of cylinder bottom surface
Envelope, the side port of Bu Shi beakers connects extract system, is then intended to the solid of separation, liquid mixture and pours top into, liquid component exists
Beaker is drawn under negative pressure effect, solid stays in top, is usually used in Experiment of Organic Chemistry extracting crystallization.In chemical laboratory
During the practical operation of crystallization experiment, due to the effect of vacuum filtration, filter paper can be close to cylinder bottom surface after the completion of suction filtration, take out filter paper
And operated during filter cake on filter paper it is cumbersome, it is general using spoon scraping, inconvenient operation, and easily cause crystal
It is unrestrained.
Utility model content
The utility model purpose is to provide a kind of assembly type Buchner funnel, easy to operate during suction filtration, moreover it is possible to solve suction filtration
After the completion of crystal the technical problem such as be not easily taken out, trickle down.
Set some equal on assembly type Buchner funnel described in the utility model, including funnel body, funnel body madial wall
Position corresponding with each guide groove sets support slot in the guide groove of even distribution, funnel body inner bottom wall, and each support slot is intersected at
The center of circle of funnel body inner bottom wall；Funnel body peripheral hardware filter paper supports basket, and filter paper support basket includes bracing ring, guide rod, support
Bar, guide rod is coincide with the size of guide groove and quantity is equal, and support bar is coincide with the size of support slot and quantity is equal, filter paper
Support basket can be in the case where guide groove and guide rod coordinate in insertion funnel body.
Handle is set on bracing ring.
Filter paper support basket material is stainless steel, and stainless steel is rigidly strong, not flexible, is conducive to the patch to funnel body inwall
Close, moreover it is possible to provide effective support to filter paper and crystal.
Some equally distributed air-vents are set on support bar, it is to avoid because blocking for support bar causes to be evacuated blind area.
It is oriented to rod outer surface curved, the arc and funnel body madial wall coincide, filter paper is to leakage when being conducive to suction filtration
The laminating of bucket body madial wall.
Support rod outer surface is plane.
The utility model compared with prior art, has the advantages that.
The utility model is novel in design, and filter paper support basket can be inserted in funnel body in the case where guide groove and guide rod coordinate,
Suction filtration, which completes filter paper support basket, to be pulled out out of funnel body, while being provided a supporting role to filter paper by the knot on filter paper and filter paper
Brilliant thing is taken out of, easy to operate, solves crystal after the completion of suction filtration and the technical problem such as is not easily taken out, trickles down.
Brief description of the drawings

The top view of funnel body in Fig. 2, Fig. 1；
The partial enlarged drawing of support bar in Fig. 3, Fig. 1；
The partial enlarged drawing of guide rod in Fig. 4, Fig. 1.
In figure：1st, funnel body 2, guide groove 3, support bar 4, guide rod 5, bracing ring 6, handle 7, support slot
8th, air-vent.
Embodiment
The utility model is described further with reference to embodiment and Figure of description.
Such as Fig. 1-4, this uses new described assembly type Buchner funnel, including funnel body 1, the madial wall of funnel body 1
On set and set support slot 7, each with the corresponding position of each guide groove 2 in three uniform guide grooves 2, the inner bottom wall of funnel body 1
Support groove 7 intersects at the center of circle of the inner bottom wall of funnel body 1；The peripheral hardware filter paper of funnel body 1 supports basket, and filter paper support basket includes bracing ring
5th, guide rod 4, support bar 3, guide rod 4 is coincide with the size of guide groove 2 and quantity is equal, the size of support bar 3 and support slot 7
It coincide and quantity is equal, filter paper support basket can be in the case where guide groove 2 and guide rod 4 coordinates in insertion funnel body 1.
Handle 6 is set on bracing ring 5.
Filter paper support basket material is stainless steel.
Some equally distributed air-vents 8 are set on support bar 3.
The outer surface of guide rod 4 is curved, and the arc coincide with the madial wall of funnel body 1.
The outer surface of support bar 3 is plane.
The utility model in use, support basket to insert funnel body in the case where guide groove 2 and guide rod 4 coordinate filter paper first
In 1, carry out after the completion of suction filtration operation, suction filtration, support basket to be pulled out out of funnel body 1 filter paper, while providing support to filter paper
The crystal on filter paper and filter paper is taken in effect out of, directly takes out filter paper and crystal, easy to operate, after the completion of solving suction filtration
Crystal such as is not easily taken out, trickled down at the technical problem.
