Abstract
The utility model relate to a kind of can the Buchner funnel of auto injection, belong to chemical apparatuses field.It comprises funnel body (1), be positioned at the seal cover (3) at funnel body top and the charging aperture (2) that is arranged at above funnel body sidewall and the flexible pipe (4) be connected on charging aperture (2).When producing or experiment needs to add feed liquid (5), first seal cover (3) is connected on funnel body (1), one end of flexible pipe (4) is connected on charging aperture (2), and the other end then reaches in feed liquid (5).Under the effect of vavuum pump, pressure in Buchner funnel body (1) is lower than atmospheric pressure, and then feed liquid (5) sucks in Buchner funnel by flexible pipe (4) and charging aperture (2) automatically from receiver, realizes reinforced object.When feed liquid is added to a certain amount of, flexible pipe (4) can be taken out from feed liquid (5), stop charging.The utility model has the advantages that: quick and convenient, automatic feeding, reduce artificial, prevent feed liquid free and easy.
Description
Technical field
The utility model relate to a kind of can the Buchner funnel of auto injection, belong to chemical apparatuses field.
Background technology
Buchner funnel is a kind of filtering apparatus conventional in laboratory.Buchner funnel is a kind of pumping and filtering device coordinating Bu Shi flask to connect extract system to use, and major part belongs to ceramic quality, also has glass and plastic material, uses vacuum or negative pressure suction to filter.Be usually used in extracting crystallization in Experiment of Organic Chemistry.After the filtration of this situation completes, the impurity of crystal surface can also be washed up off with a small amount of neat solvent.At present, when using Buchner funnel to carry out suction filtration operation, need constantly in funnel, to pour feed liquid to be filtered into.This is a very numerous and diverse thing, and easily causes feed liquid free and easy.
Utility model content
Technical problem to be solved in the utility model is exactly need artificial constantly feed supplement for prior art and easily cause the defect of feed liquid unrestrainedness, provide a kind of can the Buchner funnel of auto injection.
For solving the problems of the technologies described above, of the present utility modelly a kind ofly the Buchner funnel of auto injection can to comprise Buchner funnel body and be positioned at Buchner funnel bodies top for playing the seal cover of sealing effectiveness.It is characterized in that: charging aperture is set above existing Buchner funnel body sidewall, charging aperture is connected with flexible pipe.
When the described seal cover being positioned at funnel body top is connected with funnel body, can adopt be threaded, ground connect or snap close connect.
The described seal cover being positioned at funnel body top is transparent material, in order to observe liquid level and filtration situation in funnel.
Described charging aperture is positioned at the middle and upper part of funnel, is 1cm apart from bell mouth, and the side of charging aperture is long is 2cm, and the radius of outside disc is 0.5cm.
Solvent welding, hot-melt adhesive paste, straight cutting can be adopted when described charging aperture is connected with flexible pipe to connect.
During utility model works: when producing or experiment needs to add feed liquid, first seal cover is connected to Buchner funnel bodies top, top hose is connected at charging aperture, the other end of flexible pipe is goed deep in feed liquid, under the effect of vavuum pump, pressure in Buchner funnel is lower than atmospheric pressure, and feed liquid is sucked in Buchner funnel by flexible pipe and charging aperture automatically from receiver.When feed liquid is added to a certain amount of, flexible pipe can be taken out from feed liquid, stop charging.
The utility model has the advantages that: 1, quick and convenient; 2, automatic feeding; 3, save manually; 4, prevent feed liquid free and easy.
Accompanying drawing explanation
Fig. 1 is operating diagram of the present utility model.
In figure: 1, Buchner funnel body, 2, charging aperture, 3, seal cover, 4, flexible pipe, 5, feed liquid.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, is convenient to be well understood to the present invention, but they do not form restriction to the utility model.
Of the present utility modelly as shown in Figure 1 a kind ofly the Buchner funnel of auto injection can to comprise Buchner funnel body 1 and be positioned at Buchner funnel body 1 top for playing the seal cover 3 of sealing effectiveness.It is characterized in that: charging aperture 2 is set above existing Buchner funnel body 1 sidewall, charging aperture 2 is connected with flexible pipe 4.
When the described seal cover 3 being positioned at funnel body 1 top is connected with funnel body 1, can adopt be threaded, ground connect or snap close connect.
The described seal cover 3 being positioned at funnel body 1 top is transparent materials, in order to observe liquid level and filtration situation in funnel.
Described charging aperture 2 is positioned at the middle and upper part of funnel, is 1cm apart from bell mouth, and the side of charging aperture is long is 2cm, and the radius of outside disc is 0.5cm.
Described charging aperture 2 can adopt solvent welding, hot-melt adhesive paste, straight cutting to connect when being connected with flexible pipe 4.
The course of work of the present utility model is: as shown in Figure 1, when producing or experiment needs to add feed liquid 5, the seal cover 3 being positioned at Buchner funnel body 1 top is connected on Buchner funnel body 1, one end of flexible pipe 4 is connected on the charging aperture 2 above Buchner funnel body sidewall, and the other end then reaches in feed liquid 5.Under the effect of vavuum pump, the pressure in Buchner funnel body 1 is lower than atmospheric pressure, and then feed liquid 5 sucks in Buchner funnel body 1 by flexible pipe 4 and charging aperture 2 automatically from receiver, realizes reinforced object.When feed liquid is added to a certain amount of, flexible pipe 4 can be taken out from feed liquid 5, stop charging.
