A liquid outlet tube communicated with the cavity is arranged on the top of the outer glass layer, and a liquid inlet tube communicated with the cavity is arranged at the bottom of the outer glass layer. Solvent can be circulated between the inner glass layer and the outer glass layer and can be selected according to needs, the dropped material can be heated by circulated hot water and can be balanced by ice salt water or circulated alcohol when in low temperature, so that required uniform temperature of the dropped material is guaranteed, the experiment can be more convenient in operation, experiment results can be more stable and reliable, and affection on experiment results due to ununiformity of feeding is eliminated.
Description
Technical field
The utility model relates to a kind of experiment and uses glassware, specifically relates to a kind of constant temperature tap funnel.
Background technology
Tap funnel is a reinforced glassware commonly used in the laboratory, comprises 2 kinds of constant voltage and normal pressure tap funnels, and existing tap funnel major part is only processed with single-glass.In organic synthesis, because the solubility with temperature of material in solvent changes,, usually need be incubated heating for guaranteeing to feed in raw material evenly, existing tap funnel generally can't be accomplished, solute can occur and separate out, and stops up the situation of piston; When perhaps dripping solidfying point a little more than the material of room temperature for needs, existing tap funnel also can't normally use; To adopt heating wire to be layered on sometimes on glass for meet requirements in some cases, and there are a lot of defectives in this kind type of heating, and for example its heating is inhomogeneous, and for organic solvent, certain danger is arranged; In another kind of reaction, the material of dropping possibly be heat-labile, and perhaps reaction is more violent, all need drip low-temperature material, and existing tap funnel also can't be accomplished.
Summary of the invention
The utility model provides a kind of constant temperature tap funnel, and this tap funnel both can be used for conventional occasion, also can be used for occasion that dropping temperature is had higher requirements, and applicability is wide, and is practical.
A kind of constant temperature tap funnel; Comprise the liquid storage body, the liquid storage bodies top is provided with charge door, and the bottom is provided with and drips pipe; Drip pipe and be provided with control cock; Described liquid storage body sidewall is made up of interior glassy layer and outer glassy layer, and interior glassy layer is tightly connected with the tip edge and the bottom edge of outer glassy layer each other, forms the fully enclosed cavity between the layer glass layer; Outer glassy layer top is provided with the drain pipe that is communicated with cavity, and the bottom is provided with the feed tube that is communicated with cavity.
In the actual use, be used to deposit the liquid that needs drip in the liquid storage body.The cavity that forms between interior glassy layer and the outer glassy layer is used for the circulation of solvent.Solvent types can be confirmed according to actual needs.
Be provided with the catheter that the top port is communicated with cavity in the described dropping pipe, the catheter top is tightly connected with dropping pipe top.The setting of catheter guarantees that dropping liquid directly splashes in the reaction system, prevent dropping liquid stick on the reaction vessel inwall and cause reacting not exclusively.
For the situation that need in closed system, drip liquid, in the optimized technical scheme, be provided with the transition phase that is communicated with between described charge door and the liquid storage body; Transition phase is provided with the conduction pipe that both are communicated with dripping between the tube wall.Like this,, guarantee pressure equilibrium between the two, avoid owing to pressure differential strengthens the problem that causes dropping liquid to drip smoothly gradually because conduction pipe is communicated with the dropping liquid upper space with reaction vessel.
For needs fully enclosed system, evaporate into the external world for preventing dropping liquid or reactant liquor, in the optimized technical scheme, described charge door is the ground setting.Be similarly the increase leakproofness, can select described dropping pipe lower port is the ground setting.
The port of feed tube and drain pipe generally is communicated with external device through flexible pipe, and this moment, the port outer wall of described feed tube and drain pipe was protruding the setting, to improve feed tube and drain pipe and flexible pipe bonded assembly fastness.
The constant temperature tap funnel of the utility model can circulating solvent between the double glass, and solvent can be adjusted as required; As can use hot water circulation when heating, can use brine ice during low temperature, perhaps alcohol circulation; Guaranteed to drip the required uniform temperature of material; Make experimental implementation convenient, observed data is more reliable and more stable, has eliminated because reinforced inhomogeneous influence to observed data.

Fig. 1 is a kind of structural representation of embodiment of the constant temperature tap funnel of the utility model;
Fig. 2 is the structural representation of another kind of embodiment of the constant temperature tap funnel of the utility model;
Fig. 3 is the left view of constant temperature tap funnel shown in Figure 2.
The specific embodiment
As shown in Figure 1, first kind of embodiment of the utility model, a kind of constant temperature tap funnel; Comprise liquid storage body 1, liquid storage body 1 top is provided with charge door 2, and the bottom is provided with and drips pipe 3; Drip pipe 3 and be provided with control cock 4; Liquid storage body 1 sidewall is made up of with outer glassy layer 6 interior glassy layer 5, and interior glassy layer 5 is tightly connected with the tip edge and the bottom edge of outer glassy layer 6 each other, forms fully enclosed cavity 7 between the layer glass layer; Outer glassy layer 6 tops are provided with the drain pipe 8 that is communicated with cavity 7, and the bottom is provided with the feed tube 9 that is communicated with cavity 7.
Drip in the pipe 3 and be provided with the catheter 10 that the top port is communicated with cavity 7, catheter 10 top are tightly connected with dropping pipe 3 top.The setting of catheter 10 guarantees that dropping liquid directly splashes in the reaction system, prevent dropping liquid stick on the reaction vessel inwall and cause reacting not exclusively.Catheter 10 bottom ports are the angle setting, are convenient to dropping liquid and drip smoothly.
The port outer wall of feed tube 9 and drain pipe 8 is protruding the setting, to improve feed tube 9 and drain pipe 8 and flexible pipe bonded assembly fastness.Inlet point 2 is the ground setting with the port of the bottom that drips pipe 3, is convenient to be tightly connected with other devices.
Above-mentioned constant temperature tap funnel generally is used for the occasion of constant temperature normal pressure, charge door 2 general uncovered settings in the use.Different according to actual use occasion, feed tube 9 perhaps cools off solvent with hot water and is connected.
Shown in Fig. 2 and 3; The another kind of embodiment of the utility model; This constant temperature tap funnel is with the difference of first kind of embodiment: between inlet point 2 and liquid storage body 1, be provided with the transition phase 11 that is communicated with, transition phase 11 is provided with the communicating pipe 12 that both are communicated with dripping between pipe 3 outer walls.This tap funnel can be used for the occasion that need in enclosed system, drip, and this moment, inlet point 2 can seal with sealing plug, being provided with of communicating pipe 12 guarantee dropping liquid up and down pressure equate, guarantee the smooth dropping of dropping liquid.
