Description
Technical field
The utility model belongs to glass experimental apparatus technical field, is specifically related to a kind of reflux condensate device providing atmosphere of inert gases in chemical reaction process.
Background technology
Condenser pipe is a kind of laboratory equipment as facilitating condensation, usually be made up of one li of one outer two glass tube, wherein less glass tube runs through larger glass tube, and it utilizes heat exchange principle to make condensing gas cool a kind of glass apparatus being condensed into liquid.There is roll line at the interior pipe two ends of condenser pipe, can connect other equipment of experimental provision, allow hotter gas or liquid stream condensation through interior pipe.Outer tube is the usual opening had in both sides one on the other then, the plastic pipe of delivery cooling material (as water) of plugging into.During use, the under shed of outer tube is docked with tap usually, above automatically flowing to, reaches to larger cooling effect because water understands heat in condenser pipe.For in distillating liquid or organic synthesis, play condensation or backflow effect.Reflux and distillation are two experimental provisions often using condenser pipe.Conventional condenser pipe has straight shape, spherical and snakelike three kinds, and wherein serpentine condenser is used for the backflow of organic synthesis, and condensation efficiency is high.But traditional condenser pipe all cannot provide the function of inert gas shielding, for the reaction needing inert gas shielding, just can only carry out by connecting inert gas protection device at condenser pipe upper end open place.
Summary of the invention
The technical problem that the utility model solves there is provided a kind of reflux condensate device providing atmosphere of inert gases in chemical reaction process.
The utility model adopts following technical scheme for solving the problems of the technologies described above, a kind of reflux condensate device that atmosphere of inert gases is provided in chemical reaction process, it is characterized in that the serpentine condenser comprising glass straight tube He be arranged at glass straight tube inside, wherein the bottom of glass straight tube is provided with reaction bulb connector, the top of glass straight tube is provided with tube connector, tube connector is provided with three-way valve, three interfaces of this three-way valve respectively with glass straight tube, inert gas air inlet and gas displacement mouth communicate, inert gas air inlet is connected with inert gas tank by pipeline, gas displacement mouth is connected with negative-pressure air fan by pipeline, the head and the tail two ends of serpentine condenser are run through glass straight tube sidewall respectively and are extended to outside glass straight tube, the upper side interface of serpentine condenser is condensed water delivery port, the lower side interface of serpentine condenser is condensed water water inlet.
Compared with prior art, control repeatedly vacuumize and pass into inert gas by glass straight tube upper end three-way valve in succession in course of reaction of the present utility model, thus make whole reaction system reach inert gas shielding.Meanwhile, the design feature of serpentine condenser increases the contact area of liquid to be condensed and cooling fluid, reaches high-efficiency condensation.

In figure: 1, glass straight tube, 2, serpentine condenser, 3, reaction bulb connector, 4, tube connector, 5, three-way valve, 6, inert gas air inlet, 7, gas displacement mouth, 8, condensed water delivery port, 9, condensed water water inlet.
Detailed description of the invention
Describe particular content of the present utility model by reference to the accompanying drawings in detail.A kind of reflux condensate device that atmosphere of inert gases is provided in chemical reaction process, comprise glass straight tube 1 and the serpentine condenser 2 being arranged at glass straight tube 1 inside, wherein the bottom of glass straight tube 1 is provided with reaction bulb connector 3, the top of glass straight tube 1 is provided with tube connector 4, tube connector 4 is provided with three-way valve 5, three interfaces of this three-way valve 5 respectively with glass straight tube 1, inert gas air inlet 6 and gas displacement mouth 7 communicate, inert gas air inlet 6 is connected with inert gas tank by pipeline, gas displacement mouth 7 is connected with negative-pressure air fan by pipeline, the head and the tail two ends of serpentine condenser 2 are run through glass straight tube 1 sidewall respectively and are extended to outside glass straight tube 1, the upper side interface of serpentine condenser 2 is condensed water delivery port 8, the lower side interface of serpentine condenser 2 is condensed water water inlet 9.
The utility model is for avoiding in reaction condensation process because entering of air makes reactant oxidation deterioration become accessory substance, its reaction principle is after the reaction bulb connector 3 of condensing unit and reaction bottleneck being connected, to be extracted the air in glass straight tube 1 by gas displacement mouth 7 with negative-pressure air fan, making it inner is vacuum, make inert gas enter from inert gas air inlet 6 in glass straight tube 1 after closing gas displacement mouth 7 by regulating three-way valve door 5 again, then regulating three-way valve door 5 closes inert gas air inlet 6 and gas displacement mouth 7 simultaneously; In serpentine condenser 2, pass into condensed water, condensed water is entered from condensed water water inlet 9 and flows out from condensed water delivery port 8 again; Heating reaction bulb, solvent evaporation enters in glass straight tube 1, because serpentine condenser 2 can make the abundant condensation by contact water of solvent vapo(u)r for serpentine design, its condensation efficiency is greatly improved than traditional condenser pipe.
More than show and describe general principle of the present utility model; principal character and advantage; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present utility model.
