Abstract
The utility model relates to a buchner funnel for automatically feeding a material, which belongs to the field of a chemical apparatus, and solves the problems that manpower is needed to continuously supply fluid in the existing experiment or production process, and the exchange of filter paper is not convenient caused by excessive added fluid. The buchner funnel comprises a buchner funnel body; a taper bottle is connected to the lower end of the buchner funnel body; the buchner funnel body is connected with a glass container through a glass tube; a sealing cover is arranged at the top part of the glass container; one end of the glass tube, connected with the glass container is higher than one end of the glass tube, connected with the buchner funnel body; and a manual valve is arranged on the glass tube. The buchner funnel is simple to operate in the production process, does not need to feed material to the cylinder by manpower in the filtering process, and ensures the production continuity. The position of the highest liquid level of the liquid inside the cylinder is determined by the position of an open pore in the inner side of the cylinder; the liquid inside the cylinder is not too much in the production process; the filter paper can be changed conveniently; and the filtering efficiency is also improved.
Description
Technical field
The utility model relates to a kind of novel Buchner funnel, is a kind of Buchner funnel of automatic feeding specifically, belongs to the chemical apparatuses field.
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, and is shaped as oblate tubular, has opened a lot of apertures on the cylinder bottom surface, connects a long and narrow tubular outlet down.When using, general filter paper on the pad of cylinder bottom surface earlier, funnel injected Bu Shi flask top opening and with sealing joint (for example using rubber ring), the side mouth of Bu Shi beaker connects extract system (for example establishing vacuum inlet), solid, the liquid mixture that desire is separated poured the top into then, liquid component is drawn into beaker under the negative pressure effect, solid is stayed the top.Buchner funnel is in pharmacy, and chemical industry has a wide range of applications in the health care of food experiment process, is bringing into play immeasurable effect in filtering technique.
Existing Buchner funnel needs hand stock after the feed liquid in the cylinder has been aspirated in the process of using.After if reinforced untimely feed liquid in cylinder has been aspirated, vacuum may be inhaled filter paper broken; If overcharge, the filter paper aperture stops up the reduction of suction filtration efficient when solid particle is too much, need all pour out the feed liquid in the cylinder when changing filter paper and change filter paper again.Bring great inconvenience so all for experiment and production.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned defective, and a kind of Buchner funnel of automatic feeding is provided.It can judge the liquid level of feed liquid in the cylinder, when the liquid level in the cylinder is less than when a certain amount of can automatic liquid supply; Can stop charging when being added to automatically when a certain amount of.
The technical solution adopted in the utility model is: it comprises Buchner funnel, the Buchner funnel lower end is connected with conical flask, described Buchner funnel is connected with glass container by glass tube, the glass container top is provided with seal cover, the end that glass tube is connected with glass container is higher than the end that glass tube is connected with Buchner funnel, and glass tube is provided with manually-operated gate.
The utility model technical scheme preferably is: described glass container bottom is provided with support.
The utility model is simple to operate in the process of producing, and does not need in the process of filtration manually constantly to feed in raw material the continuity of the production of assurance in cylinder.In the cylinder determining positions of STH the highest liquid level position of liquid in the cylinder, the liquid that can not in the process of producing in the cylinder is too much, and is also more convenient when changing filter paper, improved the efficient of filtering.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1-conical flask; 2-Buchner funnel; 3-hole; 4-manually-operated gate; 5-glass tube; 6-seal cover; 7-glass container; 8-support.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the present invention, but they do not constitute restriction to the utility model.
As shown in Figure 1, the utility model comprises Buchner funnel 2, Buchner funnel 2 lower ends are connected with conical flask 1, Buchner funnel 2 is connected with glass container 7 by glass tube 5, glass container 7 tops are provided with seal cover 6, the end that glass tube 5 is connected with glass container 7 is higher than the end that glass tube 5 is connected with Buchner funnel 2, and glass tube 5 is provided with manually-operated gate 4, and glass container 7 bottoms are provided with support 8.
During installation, as shown in Figure 1, the suitable height in side of the cylinder of Buchner funnel 2 is opened a hole 3, hole 3 connects glass tube 5, adorn a manually-operated gate 4 on the glass tube 5, the other end of glass tube 5 is connected a glass container 7 vertically upward again with the end in hole 3 on connecing cylinder sides, and glass container 7 is used for the feed liquid that splendid attire need filter, the seal cover 6 of container upper end can be opened reinforced, adds material and can cover sealing later.
The course of work of the present utility model is: as shown in Figure 1, feed liquid adds in the glass container 7 of glass tube 5 upper ends when producing or test beginning, open the manually-operated gate 4 on the glass tube 5, feed liquid can enter in the cylinder of Buchner funnel 2 through glass tube 5 under the effect of gravity by manually-operated gate 4, be added to when flooding on the cylinder sides hole 3 position up to feed liquid, because the upper end of glass container 7 sealing, liquid in the glass tube that glass container 7 is connected with it 5 are because atmospheric effect is held up, and the liquid in the glass container 7 flow into no longer temporarily that charging at this moment finishes in the cylinder of Buchner funnel 2.Along with the liquid level in the cylinder that carries out Buchner funnel 2 that filters begins to descend, liquid and atmosphere when liquid level is exposed in the hole 3 on dropping to cylinder sides in the glass tube 5 communicate, balance in glass container 7 and the glass tube 5 is broken, atmospheric pressure no longer holds up in glass pipe 5 and the glass container 7 liquid, liquid begins to flow in the cylinder of Buchner funnel 2 in glass container 7, when liquid level floods hole 3 again, reach balance again in glass container 7 and the glass tube 5, atmospheric pressure holds up in glass tube 5 and the glass container 7 liquid fluid infusion process again to be finished.
In the process of producing, constantly repeat the liquid of above step in glass container 7 and all filtered.If in the process of producing, need to change filter paper, in the cylinder of Buchner funnel 2 determining positions of STH 3 the highest liquid level position of liquid in the cylinder of Buchner funnel 2, liquid that can not in the process of producing in the cylinder of Buchner funnel 2 is too much, only need close manually-operated gate 4, liquid in the glass container 7 no longer flow in the cylinder of Buchner funnel 2, are replaceable filter paper after waiting in the cylinder of Buchner funnel 2 remaining small amount of liquid suction filtration intact.
