Background technology
5L pet reaction still is the pressure vessel that use for laboratory used when small-scale polyester is tested.Polyester experiment with
PTA and EG is reaction raw materials, and reaction is carried out under high temperature (280 DEG C), vacuum condition, and polyester product is full-bodied melt, often
Secondary experiment needs to clean in time reactor after terminating.The cleaning of pet reaction still is with liquid charging stock EG as solvent.When washing still, first to
Add EG in the reactor of drained material, then reactor is kept one hour at certain temperature (higher than EG boiling point) and pressure
Above, open bottom baiting valve afterwards, the salvage stores being dissolved in EG is discharged.But, due to the temperature in the kettle boiling point higher than EG,
When opening bottom baiting valve, substantial amounts of EG steam can spurt out rapidly and fill the air to whole laboratory, and this not only gives experiment
Personnel bring and scald risk and the neurotoxic injury of excess suction greatly, and substantial amounts of EG aerosol adds and washes still difficulty, causes
The pollution of environment.
Utility model content
The purpose of this utility model is the drawbacks described above for prior art, it is provided that a kind of pet reaction still, it is simple to anti-
Answer still dismounting and PROCESS FOR TREATMENT, solve EG steam when washing still and gush the difficult problem filled the air, eliminate the operational risk of experimenter, it is to avoid
The personal injuries such as scald, reduce work difficulty and intensity, it is ensured that being smoothed out of experiment.
To achieve these goals, this utility model provides a kind of pet reaction still, including:
One kettle；
One opens bolt group soon, is located at described kettle upper end；
One end cap, is covered on described kettle upper end, and described end cap is connected with described kettle by described bolt group of opening soon；
One support bracket, is arranged between described kettle and described end cap；
One kettle lowering or hoisting gear, including a lifting body and the transverse axis that is connected with described lifting body, described transverse axis and institute
State kettle to connect.
Above-mentioned pet reaction still, it is characterised in that described kettle includes kettle in a chuck and, and described chuck is sheathed
Outside described interior kettle.
Above-mentioned pet reaction still, it is characterised in that described transverse axis is connected with described chuck.
Above-mentioned pet reaction still, it is characterised in that described bolt group of opening soon is hexagon socket head cap screw.
Above-mentioned pet reaction still, described interior kettle upper end is additionally provided with and opens bolt group soon for what described hexagon socket head cap screw passed
Hole.
Above-mentioned pet reaction still, described end cap is provided with and assembles the hole slot of conjunction with described bolt of opening soon.
Above-mentioned pet reaction still, described interior kettle upper end is additionally provided with the O type seal groove of a placement O RunddichtringO.
Above-mentioned pet reaction still, described support bracket is located at what described kettle upper surface contacted with described end cap lower surface
Position.
Above-mentioned pet reaction still, described kettle volume is 5L.
Relative to prior art, effect of the present utility model is as follows:
This pet reaction still, not only changes the structure of original kettle, makes the dismounting of reactor and PROCESS FOR TREATMENT become letter
Single the most easy, and change and original wash still solvent and method, with water for washing still medium, decrease the consumption of raw material EG, keep away
Exempt from high temperature EG steam to gush the human injuries such as the scald that may bring, protected laboratory environment, it is ensured that experiment smooth
Carry out.
Below in conjunction with the drawings and specific embodiments, utility model is described in detail, but not as the limit to utility model
Fixed.

Detailed description of the invention
In conjunction with accompanying drawing, structural principle and the operation principle of the present invention are described in detail:
See Fig. 1, Fig. 2, Fig. 3.Fig. 1 is a kind of pet reaction still overall structure schematic diagram.Fig. 2: open bolt group 3 and end soon
Cover close-up schematic view at 4 assemblings.Fig. 3: kettle main sectional structure schematic diagram.This pet reaction still, changes original kettle
Structure, make the dismounting of reactor and PROCESS FOR TREATMENT become simple, and change and original wash still solvent and method, with water
For washing still medium, decrease the consumption of raw material EG, it is to avoid high temperature EG steam gushs the human injuries such as the scald that may bring,
Protect laboratory environment, it is ensured that being smoothed out of experiment.
The pet reaction still that this utility model provides, including:
One kettle 1；
One opens bolt group 3 soon, is located at this kettle 1 upper end；
One end cap 4, is covered on this kettle 1 upper end, and this end cap 4 is opened bolt group 3 soon and is connected with this kettle 1 by this；
One support bracket 2, is arranged between this kettle 1 and this end cap 4；
One kettle lowering or hoisting gear 5, including a lifting body 51 and the transverse axis 52 that is connected with this lifting body 51, this transverse axis 52
It is connected with this kettle.
Wherein, kettle 1 is made up of chuck 11 and interior kettle 12, and kettle volume is 5L, and wherein, this opens bolt group 3 soon for interior
