Abstract
The invention discloses a liquid dropping funnel, comprising an inner conical type ground, a main pipe body, a piston, an outer conical type ground, a branch pipe and a ground plug; the inner conical ground, the main pipe body, the piston, the outer conical type ground and the branch pipe are sequentially connected, the inner ground is connected with the ground plug, and the ground plug is provided with an air hole which is matched with an air hole of the inner ground. Compared with the prior art, the liquid dropping funnel has the beneficial effects that: an outer glass ground is arranged between the main pipe body and the branch pipe, a rubber plug and the like are not used for fixing the liquid dropping funnel, the branch pipe with a certain length is connected at a connecting port of the outer conical type ground and can be inserted below the liquid level, the dropped liquid can be mixed with a reaction liquid uniformly, the volatilization of the dropped liquid in a heating system is reduced, thereby increasing the producing efficiency, the liquid dropping funnel is simple in structure, convenient in operation and low in production cost, the connecting port of the outer conical type ground is a common port and is convenient in use, each of the ground plug and an inner conical type ground plug is respectively provided with an air hole, therefore, the liquid can be dropped under an ordinary pressure condition and a reduced pressure condition.
Description
Technical field
The present invention relates to funnel, relate in particular to a kind of tap funnel.
Background technology
Dropping is in the organic synthesis process, liquid reactants or reactant solution controlledly to be joined a basic operation in the reaction through tap funnel.Common tap funnel is divided into two kinds; A kind of main body pipe and arm of only comprising usually; In use, need after the arm place uses soft rubber ball to wait to be fixed on the flask, to drip, the use of soft rubber ball or other stoppers exists and is prone to pollute, be prone to deficiencies such as aging; Another kind is main body pipe and the arm that has outer grinding port, and its arm can not insert below the reaction liquid level, in the experiment that the limit heating edge drips, often causes the volatilization of reactant liquor, brings inconvenience for experiment and operation.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of tap funnel is provided.
Tap funnel comprises inner conical ground, main body pipe, piston, male-tapered ground, arm and grinding port plug; Inner conical ground, main body pipe, piston, male-tapered ground, arm link to each other in order; Be placed with grinding port plug on the interior ground, on grinding port plug, be provided with the air extractor vent that matches with interior ground air extractor vent.
The beneficial effect that the present invention compared with prior art has:
1) design one glass outer grinding port between main body pipe and the arm needn't re-use soft rubber ball etc. and fix tap funnel.
2) the outer grinding port interface connects the arm of an appropriate length, can insert below the liquid level, and the liquid and the reactant liquor that are added dropwise to are mixed, and can reduce the volatilization that is added dropwise to liquid in the heating systems, and yield structure is simple, easy to operate, productive costs is low thereby improve.
3) outer grinding port Interface design of the present invention is general purpose interface, and is easy-to-use.
4) grinding port plug and inner conical grinding port plug place are equipped with air extractor vent, and dropping liquid all can be used under normal pressure and decompression situation.
Description of drawings
Fig. 1 is the structural representation of tap funnel.
The specific embodiment
As shown in Figure 1; Tap funnel comprises inner conical ground 1, main body pipe 2, piston 3, male-tapered ground 4, arm 5 and grinding port plug 6; Inner conical ground 1, main body pipe 2, piston 3, male-tapered ground 4, arm 5 link to each other in order; Be placed with grinding port plug 6 on the interior ground 1, on grinding port plug 6, be provided with the air extractor vent that matches with interior ground 1 air extractor vent.
Concrete method of application: closure piston 3, reactant liquor is joined in the main body pipe 2, cover grinding port plug; Use under normal pressure like need, air extractor vent on the then accurate grinding port plug 6 and the air extractor vent on the inner conical grinding port plug 1 align, and communicate with air; Then tap funnel is inserted in the flask, makes male-tapered ground 4 and flask ground leak-tight joint, arm 5 will insert below the reaction liquid level simultaneously; Again piston 3 is opened, thus the task of completion dropping liquid.
