In order to solve the above technical problems, the technical solution of the utility model is:
The extraction kettle of one kind 1,2- pentanediol production, including autoclave body, the autoclave body is interior to be equipped with shaft, the shaft and drive
Dynamic motor drive connection, the shaft include the first stirring frame, the second stirring along multiple stirring frames, multiple stirring frames are axially arranged with
Frame and third stirring frame, and be respectively equipped in the framework of first stirring frame, the second stirring frame and third stirring frame multiple
Agitator disk and screw blade.
As an improvement technical solution, first stirring frame and third stirring frame are mirror settings on shaft top
With the U-shaped stirring frame of bottom, second stirring frame is that the rectangular stirring frame in shaft middle position is arranged in.
As an improvement technical solution, the agitator disk be polygon agitator disk.
As an improvement technical solution, the agitator disk includes disk body, and the upper surface of the disk body is uniformly provided with more
A inverted L-shaped stirring rod, the lower surface of the disk body are uniformly provided with multiple V-arrangement agitating plates.
As an improvement technical solution, multiple agitator disks are arranged on the two sides frame of stirring frame framework, multiple spiral shells
Rotation blade is arranged on the upper and lower frame of stirring frame framework, and the screw blade is equipped with multiple flow-disturbing holes.
After above-mentioned technical proposal, the beneficial effects of the utility model are:
Due to being equipped with shaft in the autoclave body of extraction kettle, for shaft along being axially arranged with multiple stirring frames, multiple stirring frames include the
One stirring frame, the second stirring frame and third stirring frame, and in the framework of the first stirring frame, the second stirring frame and third stirring frame
It is respectively equipped with multiple agitator disks and screw blade.In actual production, raw material n-pentene, formic acid and hydrogen peroxide are through after a period of time
Reaction, the intermediate product pentanediol and sodium formate of generation enter extraction kettle, adds ethyl acetate extractant, starting electricity
Machine, the first stirring frame, the second stirring frame and third stirring frame are as shaft rotates and is stirred to the material in extraction kettle mixed
It closes, while agitator disk and screw blade synergistic effect are sufficiently mixed pentanediol, sodium formate and ethyl acetate, in use
The extraction kettle for stating structure considerably increases the contact area of pentanediol, sodium formate and extractant ethyl acetate, and increases
The mobility of pentanediol, sodium formate and extractant ethyl acetate in kettle, improves extraction efficiency.
U-shaped stirring frame due to the first stirring frame and third stirring frame for mirror settings on shaft top and bottom, second
Stirring frame is that the rectangular stirring frame in shaft middle position is arranged in.Stirring frame using the above structure, is more conducive to material
It is stirred.
Due to agitator disk polygon agitator disk.Using the agitator disk of above-mentioned shape, help to increase pentanediol and acetic acid second
The contact area of ester facilitates the extraction to pentanediol.
Since agitator disk includes disk body, the upper surface of disk body is uniformly provided with multiple inverted L-shaped stirring rods, and the lower surface of disk body is equal
It is even to be equipped with multiple V-arrangement agitating plates.In extraction, agitator disk and L shape stirring rod, the collaboration of V-arrangement agitating plate to material stirring, into
One step improves the mobility of ethyl acetate, pentanediol and sodium formate, facilitates ethyl acetate molecule and comes into full contact with pentanediol,
Facilitate the extraction to pentanediol.
