Background technology

Glass cold traps are conventional a kind of experimental apparatus in chemical laboratory, make condensing gas using heat exchange principle Cooling is condensed into liquid, is used as to facilitate a kind of glass apparatus of condensation, generally has straight, spherical, snakelike three kinds of glass cold Solidifying pipe, is generally made up of one li of one outer two glass tubing, wherein less glass tubing is through in larger glass tubing.Glass is cold There is interface at the inner glass tube two ends of solidifying pipe, can connect the other equipment of experimental provision, allow hotter gas or liquid flow through inner tube And condense；Outer glass pipe then generally has opening one on the other, the conduit of delivery condensed fluid (as water) in both sides.During use, The under shed of outer glass pipe is import, and condensed fluid from bottom to top, flows out from the outlet of upper shed, reaches preferable cooling work( Effect.But, when the room temperature temperature difference of the condensed fluid in glass cold traps and outside is larger, can produce a large amount of outside glass cold traps The globule, the globule accumulation after can along glass cold traps wall downstream to connect instrument and equipment in, affect experiment effect.

In view of above-mentioned defect, the design people, actively research and innovation in addition, to founding a kind of glass cold traps, make It has more the value in industry.

Utility model content

For solving above-mentioned technical problem, the purpose of this utility model is to provide a kind of glass cold traps, this glass cold traps The globule of tube wall condensation can effectively be derived.

A kind of glass cold traps of the present utility model, including outer glass pipe and run through its interior inner glass tube, described outer In glass tubing, the edge of upper port and lower port is tightly connected with the outer wall of described inner glass tube respectively, described outer glass pipe inwall Enclose the cavity for containing condensed fluid with inner glass tube outer wall, be respectively provided with above and below described outer glass pipe The export and import of condensed fluid circulation, described inner glass tube two ends are equipped with interface, lower port and institute in described outer glass pipe The junction periphery stating inner glass tube outer wall is vertically arranged with detachable, horizontally disposed ring-type water proof circle, outside described water proof circle Enclose and be made up of rigid material, inside enclose and be made up of elaxtic seal.

Further, the apopore that described water proof circle passes through to open up is communicated with conduit.

Further, described water proof circle periphery is inclined upwardly.

Further, described inner glass tube is spherical, straight or snakelike.

Further, described interface is frosted standard interface.

Further, described rigid material is politef, and described elaxtic seal is rubber.

By such scheme, this utility model at least has advantages below：

The glass cold traps of this utility model, devise a kind of mechanism of effective process tube wall condensed exterior water, and utilizing can The ring-type water proof circle of dismounting and by apopore and its integrally formed aqueduct, effectively prevents the condensed water of tube wall from entering It is ensured that experiment is normally carried out in the experimental apparatus that lower section connects；This water proof circle periphery is made up of rigid material, effective support every Hydrosphere, inside encloses and is made up of elaxtic seal, and effective stop is oozed under water, and detachable after the completion of experiment, or uses other glass On the cold condensing tube of glass.

Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model Art means, and being practiced according to the content of description, below with preferred embodiment of the present utility model and coordinate accompanying drawing detailed Describe in detail bright as after.

Brief description

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of water proof circle in this utility model.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used for this utility model is described, but is not limited to scope of the present utility model.

Referring to Fig. 1 and Fig. 2, a kind of glass cold traps described in this utility model one preferred embodiment, including outer glass pipe 1 and run through its interior inner glass tube 2, in described outer glass pipe 1 edge of upper port 3 and lower port 4 respectively with described interior glass The outer wall of glass pipe 2 is tightly connected, and described outer glass pipe 1 inwall and inner glass tube 2 outer wall enclose for containing condensed fluid Cavity 5, is respectively provided with outlet 6 and the import 7 of condensed fluid circulation, described interior glass above and below described outer glass pipe 1 Glass pipe 2 two ends are equipped with interface 7, and in described outer glass pipe 1, lower port 4 and the junction periphery of described inner glass tube 2 outer wall are hung down Directly it is arranged with detachable, horizontally disposed ring-type water proof circle 9, described water proof circle 9 periphery is made up of rigid material 12, inside encloses by bullet Property encapsulant 13 is made.

For preventing the water excess on water proof circle 9 from overflowing, realize effective draining, described water proof circle 9 passes through the apopore opening up 10 are communicated with conduit 11.

For preventing water proof circle 9 from stopping condensed water outflow, described water proof circle 9 periphery is inclined upwardly.

Preferably, described inner glass tube is spherical, straight or snakelike, spherical and snakelike increase heat exchange area.

Use for convenience of glass cold traps, described interface is frosted standard interface 8.

Preferably, described rigid material is politef, and described elaxtic seal is rubber.

Operation principle of the present utility model is as follows：

When carrying out backflow experiment or revolving recycling design, the cavity 5 of spherical glass condensing tube or snakelike glass cold traps In the condensed fluid industrial alcohol of circulation that is passed through, because industrial alcohol temperature is too low, larger with the room temperature temperature difference, glass cold traps Outer wall can condense the globule, when the globule is excessive, can form current, outside lower port 4 and described inner glass tube 2 in outer glass pipe 1 The horizontal endless water proof circle 9 that the junction periphery of wall is vertically sheathed can effectively stop that condensed water is dirty, the condensation on water proof circle 9 Water by be connected with the apopore 10 of conduit 11 derive to wastewater trough can and, when experiment after the completion of can take off water proof circle 9, use To on other glass cold traps.

The above is only preferred implementation of the present utility model, be not limited to this utility model it is noted that For those skilled in the art, on the premise of without departing from this utility model know-why, can also do Go out some improvement and modification, these improve and modification also should be regarded as protection domain of the present utility model.
