Chemical experiment sometimes needs to carry out under cryogenic, particularly subzero forties degree or subzero eighties degree etc.
A kind of harsh conditions, it is necessary to special low-temp reaction equipment.Current laboratory, as low-temperature receiver, is manually poured into typically with liquid nitrogen container
In Dewar bottle equipped with suitable solvent such as ethanol, then solvent instantaneous solidification under cryogenic can maintain the low of a period of time
Temperature, but as the volatilization of nitrogen, solvent are slowly melted, system temperature slowly gos up；Sometimes reaction is needed for a long time
During progress, such as 24h, it is necessary to artificial timing supplement liquid nitrogen is relatively time-consuming.The general volume of other liquid nitrogen container is big, quality weight, every time
Topple over fluid infusion all very laborious.
Liquid nitrogen cryogenics reaction is general to need reaction system to carry out under anaerobic simultaneously, in order to ensure oxygen-free seal bar
Part, the magneton used in the prior art in magnetic stirring apparatus complex reaction bottle is carried out, and magnetic stirring apparatus is being arranged on Dewar bottle just
Lower section, adds the distance between magneton, hence it is evident that reduce mixing speed, and the temperature that can directly affect solvent in reactor is homogeneous
Property, so as to influence reaction mass and yield；Also someone uses polytetrafluoroethylene (PTFE) plug sleeve the stirring in agitator with sealing ring in addition
Mix on bar, be fixed on reaction bulb central closing, but be due to motor oscillating, cause sealing effectiveness bad.
Therefore, how to solve the above problems, it has also become those skilled in the art's technical barrier urgently to be resolved hurrily.
Utility model content
There is provided one kind is time saving and energy saving, fluid infusion is convenient, sealing effect for the deficiencies in the prior art for the utility model
Really good liquid nitrogen cryogenics anaerobic reaction system, solves above-mentioned technical problem.
To achieve these goals, the utility model provides following technical scheme：A kind of liquid nitrogen cryogenics anaerobic reaction system,
Including reaction unit and automatic liquid supply nitrogen device；The reaction unit includes three mouthfuls of reaction bulbs, agitating paddle and motor；The stirring
The puddler of oar passes through the adapter plug for being cased with a rubber tube, and puddler upper end passes through No. two rubber tubes and motor connection, adapter
Plug is arranged on the middle opening of three mouthfuls of reaction bulbs；The left side opening of three mouthfuls of reaction bulbs sets vacuum glass plug, right side opening
Mouth is connected by three-way valve with aerating device；The automatic liquid supply nitrogen device includes being arranged on Du immediately below three mouthfuls of reaction bulbs
Watt bottle, it is arranged on the upper left liquid nitrogen container of Dewar bottle and the ball float level controller being arranged in Dewar bottle, the Floating Ball Liquid Level
Controller includes ball float and the valve connected by lever, and the valve is connected by woven hose with liquid nitrogen container.
A rubber tube lower end is enclosed on adapter and held beyond the Great Wall in above-mentioned, and puddler is from bottom to top through adapter plug, a rubber
Vaseline, increase lubrication and sealing function are smeared on the inside of pipe upper end with puddler contact portion, such motor passes through No. two rubber
Pipe drives puddler to rotate, while can guarantee that adapter plug is not rotated.
The position of bottleneck of three mouthfuls of reaction bulbs and adapter plug, vacuum glass plug, the contact position of three-way valve are in above-mentioned
Frosted structure, adds sealing.
In above-mentioned, by rotating three-way valve, it is connected with vacuum extractor, can takes out what is itself existed in three mouthfuls of reactors
Air；Then rotate three-way valve to communicate with aerating device, aerating device filling inert nitrogen gas or argon gas ensure that
Reaction is carried out under absolute oxygen free condition.
The operation principle of above-mentioned middle automatic liquid supply nitrogen device is solvent liquid after the nitrogen worked as in Dewar bottle is slowly vapored away
Change, ball float is reduced to certain altitude with liquid level, and the liquid nitrogen that can now open in valve, liquid nitrogen container adds to Du by woven hose
In watt bottle, after ball float returns to original height, valve is closed, and stops fluid infusion；The device plays a part of timing fluid infusion, no
Need manually to keep by experimental provision for a long time, while liquid nitrogen container is fixed on Dewar bottle upper left side, it is not necessary to be lifted to reality from ground
Test on operating desk, it is time saving and energy saving, it is easy to operate.
It is preferred that, the Dewar bottle and three mouthfuls of reaction bulb peripheries set heat-insulation layer, and effect is reduction of the volatilization speed of liquid nitrogen
Degree, maintains the longer low temperature time, saves resource.
It is preferred that, temperature-detecting device is set in the Dewar bottle, and effect is more accurately to measure outside reaction bulb
Portion's temperature.
It is preferred that, the aerating device is balloon, can more easily provide inert gas source, and light weight is not
The stability of single unit system is influenceed, gas leakage situation can be whether there is by the size judgment means of observation baloon in addition.
Compared with prior art, the utility model has advantages below：The system by set automatic liquid supply nitrogen device and
The adapter plug for being cased with rubber tube is set on puddler, and simple in construction, reasonable in design, easy to operate, automaticity is high, time saving
Laborsaving, fluid infusion is convenient, good sealing effect, applied widely, is with a wide range of applications.
