The shortcomings that traditional gas recyclable device needs fixed and exhaust gas easily to reveal and cause laboratory pollution.
Anti-suck, explosion-proof principle: when experiment, if being positive pressure in conical flask 2, gas, which can rush, heaves strip latex thin skin
10, so that gas is smoothly discharged from gas vent 16；If being negative pressure in conical flask 2, strip latex thin skin 10 will tightly
The end for being attached to air guide glass inner tube 6 is inhaled, that is, has blocked gas vent 16, has blocked the reflux of gas, it is therefore prevented that liquid suck-back is existing
The generation of elephant.When preparing the gases such as readily soluble ammonia, hydrogen chloride, because gas is discharged by micro- diameter of plastic straw 14, it can make
The velocity of discharge of gas be greater than its solution rate, therefore will not because gas dissolve it is too fast due to generate liquid suck-back the phenomenon that, prevent from sending out
Raw secondary suck-back.Even if a small amount of reflux occurs because of gas dissolution, also air guide glass can be tightly attached to because of strip latex thin skin 10
The end of inner tube 6 blocks and terminates.Therefore use the device that there is dual fail-safe anti-suck effect.
It is proved by flammability test, implosion guard inner tube 11 has apparent explosion-proof, is carrying out gas flammability
When test, even if containing a certain amount of air in the imflammable gas of preparation, gas generating unit will not explode.Because from double
The tempering of the burning to come to 17 port of glass point mouth can cause after encountering explosion-proof wire mesh column 12 because heat scatters and disappears rapidly
The temperature of gas reduces and extinguishes or block, therefore the tempering burnt is difficult to burn into outer glass tube 7 and conical flask 2.
The above is only the preferred embodiment of the utility model only, is not intended to limit the protection model of the utility model
It encloses.Any modification, equivalent substitution, improvement and etc. made within the spirit and principle of the present invention, are all contained in this reality
With in novel protection scope.
