(201) and bottom (202) are set as Demountable.
9. the production method that washing reaction kettle is used in a kind of PES polyether sulfone production, it is characterised in that: production method is as follows:
Step 1: bisphenol S is dissolved in solvent sulfolane, carry out at 100-200 DEG C with sodium hydroxide or potassium hydroxide solution at
Reactant salt generates bisphenol S salt, and system, which is then warming up to 210-230 DEG C, makes bisphenol S salt and 4, and 4 '-dichloro diphenyl sulfones contract
Poly- reaction obtains reactant；
Step 2: reactant is carried out pulverization process；
Step 3: suitable washing water is added into washing reaction kettle by the metering scale on watch window, the second electricity is opened
Machine, driving agitating shaft drive stirring rod rotation, open first motor, driving bottom drive autoclave body rotation, direction of rotation with stir
The direction of rotation of axis is mixed on the contrary, the temperature in washing reaction kettle is controlled in 120-180 DEG C at this time；
Step 4: the reactant after crushing is added in washing reaction kettle, when radar level gauge detects that liquid level arrival refers to
When determining liquid level, radar level gauge will test information and feed back to control system, and control system controls stirring motor starting, drives multiple
Transmission shaft rotation, due to being cooperated between transmission shaft and screw rod by the taper flank of tooth, so that screw rod is followed by rotation, screw rod and swivel nut
Between be threadedly engaged, swivel nut is displaced outwardly, push movable plate be displaced outwardly, the first voussoir of two on movable plate is led along first
Rail slides in and out, and the first voussoir and the second voussoir inclined-plane cooperate, and two the first voussoirs are to generation extruding between two the second voussoirs
Power so that two connectors between two the second voussoirs are mutually drawn close, thus by scissor extensible member along the second guide rail to
Outer stretching, extension so that catch bar drive stirring blade it is protruding, due in three mixing components push pole length from top to bottom by
Cumulative length, therefore the order that the catch bar in three mixing components stretches out is gradually to stretch out from bottom to top, enhances mixing effect；
Step 5: stopping stirring after stirring 3-8h, that is, first motor, the second motor and stirring motor are closed, due to the first bullet
Terminals are powered by the active force of spring and second spring so that catch bar is retracted into initial position, so that the coil in pedestal is logical
Electricity generates magnetic field and bottom is sucked, so that quickly control washing reaction kettle stops operating, is filtered later, adds washing water, is anti-
It operates 2-4 times again；
Step 6: the polyether sulfone after washing is placed in 80-100 DEG C, dry 1- under the vacuum condition of 0.07-1MPa
3h；
Step 7: carrying out extrusion granulation by extruder obtains finished product.
