Abstract
The utility model relates to a primary and secondary dropping funnel and belongs to the technical field of chemical reaction glassware. The primary and secondary dropping funnel comprises a primary dropping funnel and a secondary dropping funnel, wherein the secondary dropping funnel is connected in parallel to the upper side of the primary dropping funnel through a pipeline. The secondary dropping funnel is connected in parallel to the upper side of the primary dropping funnel through the pipeline; double-dropping or constant pressure dual-functions are realized through the primary dropping funnel, the secondary dropping funnel, and control valves of the primary dropping funnel and the secondary dropping funnel; during dropping of a reaction agent, the trouble caused by bottleneck limitation can be reduced; the primary and secondary dropping funnel is practical, and convenient to operate; and the experimental accuracy is ensured.
Description
Technical field:
The utility model relates to a kind of tap funnel, particularly relates to a kind of primary and secondary tap funnel, belongs to chemical reaction glass ware technical field.
Technical background:
Dropping be in chemical reaction with liquid reactants or raw material, progressively add a kind of operation of reacting in the reactor by tap funnel.ZL200920234759.0 discloses a kind of tap funnel, comprises main body pipe and cold finger, and ground interface in the main body pipe is provided with an outer grinding port interface and, cold finger are installed in the main body pipe; But the tap funnel that ZL201120391775.8 discloses a kind of constant temperature or heated, formed by main body pipe, cock and dropper, pipe outer tube wall at the main body pipe is provided with constant temperature jacket, the constant temperature jacket bottom has water inlet, top has water return outlet, can be connected by the circulation pump that flexible pipe and thermostatic equipment carry, between main body pipe and dropper, be connected with arm.But usually need plurality of raw materials or reagent to drip simultaneously in the organic synthesis, above-mentioned two kinds of tap funnels all can't be realized this function, and because the restriction of reaction bottleneck, even employing four-necked bottle, stir at the same time, when backflow and temperature are observed, to take three bottlenecks, a bottleneck can only be arranged for tap funnel is installed; If drip two kinds of reagent, because the restriction of bottleneck need be fed in raw material from condenser top; If drip two or more reagent, can only alternately drip, this will make troubles to experimental implementation, also can have influence on the accuracy of experiment simultaneously.
Summary of the invention
The purpose of this utility model is in order to solve in the chemical reaction, and the defective of the trivial operations that exists when plurality of raw materials or reagent drip simultaneously provides a kind of primary and secondary tap funnel.
A kind of primary and secondary tap funnel comprises female tap funnel and sub-tap funnel, is parallel with a sub-tap funnel at female tap funnel upside by pipeline.
The drip nozzle of described female tap funnel and the drip nozzle of sub-tap funnel are mutual socket.
The beneficial effects of the utility model are: be parallel with a sub-tap funnel at female tap funnel upside by pipeline, realize two dropping liquids or constant voltage dual-use function by primary and secondary tap funnel and control cock thereof, when carrying out the reaction reagent dropping, can reduce because the trouble that the bottleneck restriction brings, practical and easy to operate, and guaranteed the accuracy of testing.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of primary and secondary tap funnel comprises female tap funnel 1 and sub-tap funnel 2, is parallel with a sub-tap funnel 2 at female tap funnel 1 upside by pipeline.
The drip nozzle of the drip nozzle of described female tap funnel 1 and sub-tap funnel 2 is mutual socket, is convenient to operation and uses.
The utility model is fixed on the iron stand, the drip nozzle of primary and secondary tap funnel is positioned on the reaction bulb bottleneck, close the control cock 3 of female tap funnel 1 and the control cock 4 of sub-tap funnel 2, two kinds of different reaction reagents are injected into respectively in female tap funnel 1 and the sub-tap funnel 2.When needs drip a kind of reaction reagent, open the control cock 3 of female tap funnel or the control cock 4 of sub-tap funnel, can drip the reaction reagent of female tap funnel 1 or the reaction reagent of sub-tap funnel 2; When needs drip two kinds of reaction reagents, open the control cock 3 of female tap funnel and the control cock 4 of sub-tap funnel simultaneously, can drip the reaction reagent of female tap funnel 1 and the reaction reagent of sub-tap funnel 2 simultaneously.
Claims (2)
