Abstract
The utility model discloses a multilayer filtration Buchner funnel device. The multilayer filtration Buchner funnel device is characterized in that an assembling method comprises the following processes that 1, a ceramic filter mold is sleeved on the traditional Buchner funnel and the ceramic filter mold and the traditional Buchner funnel are isolated by a rubber gasket and are fastened by a lock catch; 2, another ceramic filter mold is sleeved on the ceramic filter mold and the upper and lower two ceramic filter molds are isolated by a rubber gasket and are fastened by a lock catch; and 3, one or more ceramic filter mold are orderly sleeved on the upper ceramic filter mold, wherein the assembling process is the same as the previous processes, in use, filter papers having different specifications can be orderly put on pore plates of all layers of the filter molds from up to bottom. The multilayer filtration Buchner funnel device solves the intractable problems of the traditional Buchner funnel, can be operated simply, has a low cost and can satisfy price and practicality requirements of a laboratory and companies.
Description
Technical field
The utility model is improving on its device take traditional Buchner funnel as basic, can better be applied in the experimentation of suction filtration, for experimental study work is contributed.
Background technology
Buchner funnel is a kind of ceramic instrument that uses in the laboratory, and also useful plastic production is used for using the suction of vacuum or negative pressure to filter.Generally believe that the inventor is Nobel chemistry Prize winner Edward Joachim Büchner in 1907, in fact Buchner funnel is invented by chemist ErnstB ü chner.Be shaped as oblate tubular, opened a lot of apertures on the cylinder bottom surface.Long and narrow tubular outlet of lower company.When using, general first filter paper on the pad of cylinder bottom surface injects Bu Shi flask upper opening with funnel and with sealing joint (for example using rubber ring).The side mouth of Bu Shi beaker connects extract system.Then solid, the liquid mixture that wish is separated poured the top into, and liquid component is drawn into beaker under the negative pressure effect, and solid is stayed the top.Be usually used in extracting in the Experiment of Organic Chemistry crystallization.After the filtration of this situation is finished, can also wash up the impurity of crystal surface off with a small amount of neat solvent.
The utility model content
The composition of the utility model innovative product is a traditional Buchner funnel, puts a ceramic filter mould in the above, middle separate with rubber washer, and with snap close fastening Buchner funnel and ceramic filter mould; On the ceramic filter mould, put a ceramic filter mould, the centre separates with rubber washer, and with snap close fastening two ceramic filter moulds up and down, then put again successively one or several ceramic filter moulds, assemble method is identical with back, when using, it puts the filter paper of different size at the orifice plate of every layer of filter by order from top to bottom, easily stop up filter paper and make the rate of filtration this problem that slows down with regard to solving traditional Buchner funnel filter residue, secondly it can also solve the filtration problem of some specific (special) requirements.
Description of drawings
Fig. 1 is a kind of multiple filtration Buchner funnel device
Fig. 2 is the ceramic filter mould
The specific embodiment
Below in conjunction with accompanying drawing and its specific embodiment utility model is described in further details.
1. ceramic filter mould: similar with the model of Buchner funnel, just the lower end is cylinder type, and wide at the top and narrow at the bottom, is convenient to be nested with next mould
2. rubber washer: pad prevents that the suction filtration system from leaking gas between the bottom and next ceramic filter mould of a upper ceramic filter mould.
3. snap close: two ceramic filter mold locks prevent the gas leakage of suction filtration system together up and down.
Innovation is summed up:
1. the innovation product focuses on, and it can solve traditional Buchner funnel filter residue and easily stop up filter paper and make the rate of filtration this problem that slows down, and secondly it can also solve the filtration problem of some specific (special) requirements.Such as, distinguish respectively the disposable filtering of the big or small filter residue of multiple difference etc.This product device is simple, and is cheap, is easy to promote.
2. to the prospect of innovative product: wish that the innovation product can bring convenience for laboratory and some enterprises, make the experimenter do not blocked because of filter residue filter paper filter slowly worried, thereby can better engage in experimental study, for society makes larger contribution.
Claims (1)
1. multiple filtration Buchner funnel device, it is characterized in that: its part and assembling sequence thereof are a traditional Buchner funnel, put a ceramic filter mould in the above, middlely separate with rubber washer, and with snap close fastening Buchner funnel and ceramic filter mould; On the ceramic filter mould, put a ceramic filter mould, the centre separates with rubber washer, and with snap close fastening two ceramic filter moulds up and down, then put again successively one or several ceramic filter moulds, assemble method is identical with back, puts the filter paper of different size when it uses at the orifice plate of every layer of filter by order from top to bottom.
