Installation and precautions for glass reactors

Unpacking and pre-installation preparation 1) Open the box and check the assembly
according to the packing list.
2) Remove the frame from the box, place the flat floor or tabletop, and level the base and frame
.
3) Carefully clean the glass device so that its cleanliness meets the test requirements
.
Note: Glass devices are fragile, please remove them carefully
.
Kettle body installation The kettle body has been installed on
the frame when it is shipped.
Stir paddle, kettle cover installation Put flat section bolts, the stirring paddle is gently placed in the kettle body, the kettle mouth and the kettle cover mouth are evenly coated with silicone grease and put PTFE gasket, and the kettle cover, the kettle cover gasket and the kettle cover pressure plate are installed in turn, and the bolts are pre-tightened after adjusting the position of
the kettle cover 。 Stir guide installation Remove the stir guide and loosen the upper nut; Pass the stirring paddle through the stirring seal; The stirring seal body cone is mounted on the corresponding stirring port of the kettle lid face down, and a small amount of silicone grease is applied to the cone surface; The sealing cone, the upper end of the sealing support ring, the locking sleeve, and the upper screw are successively mounted on the mixing paddle, pay attention not to fix, and lock the upper nut
after adjusting the height of the mixing paddle.
The height of the stirring paddle is greater than 20mm from the bottom of the kettle to avoid collision
with the kettle body.
Installation of the top agitator The top mixer is installed on the head holder in the direction indicated by the red arrow; The alignment can be checked by adjusting the motor holder and guide sleeve so that it is installed in the right position, locking the top stirrer lock nut, and then locking the top wire
.
Nozzle installation Constant pressure funnel, condenser, temperature sensor, feeding valve installation Constant pressure funnel, condenser mounted on the
kettle cover.
The suction joint is mounted at the top of
the condenser.
The flask clip is secured, and the temperature sensor and the dosing valve are installed in their respective interfaces
.
Operation precautions 1) The solid material or liquid material is slowly added to the kettle body through the feeding port
.
2) Adjust the set speed and start the stirring motor
.
3) According to the needs of the reaction, open the supporting vacuum device and extract the reactor to the state of
required pressure.
4) According to the needs of the reaction, open the supporting heating (refrigeration) circulation device to meet the temperature control requirements
.
5) After the reaction is completed, the temperature control heating or refrigeration function is turned off according to the actual situation, and the circulation device
should be turned off when the material temperature in the kettle is close to room temperature.
Note: After the circulating device of the temperature control product is closed, the valve in the circulation pipeline cannot be closed; So as not to cause the liquid to burst due to thermal expansion and contraction 6) Turn off the vacuum acquisition device
.
7) Change the speed setting value to the minimum value and stop the stirring work
.
8) Power
off the controller.
9) The discharge port of the self-discharge valve
.
After the discharge is completed, please remove the discharge valve in time and carefully clean the discharge valve and the discharge port
.
10) Reinstall the discharge valve
.
Tip: When discharging, the black knob
at the lower end of the discharge valve should be adjusted counterclockwise.
After the glass device is cleaned, wipe the attached liquid inside and outside the device with a clean soft cloth to avoid contamination
.
