Description
【Technical field】
Technical field of chemical is the utility model is related to, more particularly 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.Oblate tubular is shaped as, many apertures have been opened on cylinder bottom surface, lower one long and narrow tubular of company goes out
Mouthful.When use, the general first filter paper on the pad of cylinder bottom surface, back taper cylinder is injected into Bu Shi flasks upper opening and by interface
Sealing (such as：Rubber ring).The side port of Bu Shi beakers connects extract system.Then it is intended to the solid of separation, liquid mixture is poured into
Top, liquid component are drawn into beaker under negative pressure effect, and solid stays in top.But when cleaning, filtration fraction
Long and narrow tubular outlet below is difficult to thoroughly clean up, and especially for some stickums, cleaning up is extremely difficult, and
And solid stockpiles excessive also bad removing.A kind of therefore, it is proposed that Buchner funnel.
【Utility model content】
Main purpose of the present utility model is to provide a kind of Buchner funnel, by detachable upset structure, is easy to filter paper
Lay, and by splitting structure, each structure can be cleaned, greatly reduce cleaning difficulty, improve work effect
Rate, effectively can solve the problems, such as in background technology.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of Buchner funnel, including charging hopper, accept ring and funnel, the undertaking ring be arranged on charging hopper and funnel it
Between, the undertaking ring is connected by screw thread with charging hopper, is accepted ring and is connected by overturning structure with funnel.
Further, the upset dress, which includes being arranged on, accepts ring and the fixed ear on funnel and rotating shaft, the fixed ear
It is bolted.
Further, filter disc is provided with the inside of the undertaking ring, the filter disc is provided with filter paper and pressure ring.
Further, it is provided with rubber washer between the undertaking ring and funnel.
Compared with prior art, the utility model has the advantages that：By detachable upset structure, it is easy to filter paper
Lay, and by splitting structure, each structure can be cleaned, greatly reduce cleaning difficulty, improve work effect
Rate.

【Embodiment】
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
As shown in figure 1, a kind of Buchner funnel, including charging hopper 1, undertaking ring 4 and funnel 5, the undertaking ring 4 are arranged on dress
Between hopper 1 and funnel 5, the undertaking ring 4 is connected by screw thread 9 with charging hopper 1, accepts ring 4 by overturning structure and funnel 5
Connection.
A kind of Buchner funnel of the utility model is overturn charging hopper 1 by rotating shaft 8, it is necessary to when cleaning, can will be filtered
Solid is directly poured out, and rotates charging hopper 1, is removed, and so single unit system can be split, and makes each structure only
It is vertical, and when needing to filter solidliquid mixture, first filter paper 10 can be laid on filter disc 7, and by pressure ring 11 by the side of filter paper 10
Edge compresses, and is not only convenient for cleaning by splitting structure, and be easy to the lay of filter paper 10.
Wherein, rubber washer 6 is provided between the undertaking ring 4 and funnel 5, improves overall tightness.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, all should fall into the scope of protection of the utility model.
