Reaction kettle stirring is one of the common operation steps in chemical production, which can help the mixture to dissolve evenly and improve the process efficiency. However, the reactor mixing also needs to pay attention to some operational details to avoid accidents. The following will introduce some matters needing attention and solutions to common problems of reaction kettle stirring.

1. operation precautions:

1. select the appropriate mixing mode: according to the nature of the mixture and process requirements to choose the appropriate mixing mode, including blade type, anchor type, spiral type, etc.

2. Stirring speed control: according to the concentration of the mixture, viscosity and other characteristics to determine the stirring speed, to avoid speed too fast or too slow and lead to adverse effects.

3. Check the state of the agitator: Before the mixing operation, check the state of the agitator regularly to ensure that there is no abnormality.

4. Avoid blocking: When adding the mixture, pay attention to avoid adding too fast to avoid blocking the mixer and affecting the mixing effect.

5. Pay attention to safety protection: Pay attention to safety protection when mixing to ensure the safety of personnel and equipment.

2. common problems and solutions:

1. uneven mixing: may be the mixing speed is not suitable, mixing the wrong choice and other reasons, the solution is to adjust the mixing speed or replace the appropriate mixer.

2. Agitator blockage: It may be that the mixture is added too fast and the agitator is blocked. The solution is to stop the mixing operation, clean the agitator and restart the mixing.

3. Abnormal sound of agitator: It may be that the agitator is malfunctioning or worn. The solution is to replace the agitator parts in time or replace it as a whole.

through the above introduction, I believe we have understood the reaction kettle stirring operation matters needing attention and solutions to common problems. In the reaction kettle stirring operation, must be strictly in accordance with the operating procedures, keep the equipment in good condition, to ensure the safety and effect of mixing operation. If problems are encountered, stop the operation in time and take effective solutions according to the actual situation.
