Drum dryers are widely used in the food,
chemical, and pharmaceutical industries. After extended use, they may need
inspection, repair, or adjustment. Here is a general process for inspecting and
adjusting drum dryers:
- Shutdown and safety inspection: Stop the drum dryer and ensure
the power is disconnected, and the equipment is in a safe state.
- Cleaning and maintenance: Clean and maintain parts like the
drum surface, air vents, fan impeller, motor, and electrical control box;
check for abnormalities.
- Belt and drive inspection: Check the tension, alignment, and
wear of the belt and drive system; confirm the proper operation of
components like chains, sprockets, and reducers.
- Heating system inspection: Inspect the heating system,
including the boiler, steam pipeline, valves, and condensate drainage
system; confirm proper operation and heating temperature.
- Control system inspection: Check the control system, including
sensors, temperature controllers, electrical control boxes, and PLCs;
confirm proper operation.
- Test run: After inspection, test the operation and ensure all
parts are running correctly.
- Parameter adjustment: Adjust parameters if needed, such as
temperature, airflow, and material feed speed.
- Maintenance records: Record maintenance details for future
reference.
Follow safety regulations and ensure personal safety during inspection and adjustment. Untrained personnel should not perform adjustments; seek professional help if needed.
