Filament dryers are indispensable equipment in industrial production, which is used to reduce material moisture and ensure production efficiency and product quality. Proper routine maintenance can not only extend the service life of the equipment, but also ensure its normal operation and efficient performance. This paper will introduce the daily maintenance steps, skills and common problems of the filament dryer in detail.

Daily inspection and maintenance

Pre-filter check: Check the automatic blowdown valve on the pre-filter before each shift every day. If there is blockage, it should be cleaned in time. Ensuring the cleanliness of the filter is the basis for ensuring the normal operation of the dryer.

Check the running status of the device: Check whether the dryer has abnormal sound or vibration during operation. If an anomaly is found, stop the machine immediately for inspection and restart it after troubleshooting.

Temperature and humidity monitoring: Periodically check the inlet pressure and air flow of the equipment to ensure that the temperature sensor and humidity sensor are working properly. High or low temperature and abnormal humidity may affect the drying effect and even damage the equipment.

Filter replacement: Periodically check the pressure drop of the front filter and the rear filter. If the pressure drop exceeds 0.5bar, the filter element should be replaced in time. Ensuring the cleaning of the filter element can effectively improve the ventilation effect and work efficiency of the equipment.

Muffler check: Check whether the muffler is dirty and blocked. If the recoil pressure of the regenerator is too large, it indicates that the muffler needs to be replaced or cleaned.

Lubrication maintenance: Regularly lubricate the bearings, chains, gears and other parts of the dryer to reduce wear and noise. For special equipment, food grade lubricants should be used for lubrication.

Scheduled maintenance schedule

Weekly maintenance: Clean the dust and impurities inside and outside the dryer to keep the equipment clean. Check whether the equipment is corroded. If so, handle it in time.

Monthly maintenance: Check the heater, fan, control panel and other components to ensure that they work properly. Lubricate bearings, chains, gears and other components to reduce wear and noise.

Quarterly maintenance: Complete inspection of the control system, including temperature sensor, humidity sensor, control panel, etc., to ensure its normal operation.

Annual maintenance: carry out a comprehensive inspection and maintenance of the dryer, including replacing the aging parts, checking the connection of the electrical system and the condition of the wires.

Common problems and solutions

Abnormal temperature: If the temperature is found to be too high or too low, check whether the heating element and cooling system are normal, and repair or replace it if necessary.

Abnormal humidity: If the humidity is too high or too low, check whether the humidity sensor and control instrument are normal and adjust or maintain them in time.

Electrical fault: If the device cannot operate normally due to an electrical fault, check whether the connection of the electrical parts is tight or whether the wires are damaged, and repair or replace them if necessary.

Filter blockage: If the filter blockage leads to poor ventilation of the equipment, the filter element should be replaced regularly to ensure the normal operation of the equipment.

Maintenance record

To ensure the effectiveness of maintenance, it is recommended to record each maintenance and maintenance operation, including the date, operation content, and operator information. This can not only facilitate the maintenance work in the future, but also provide a reference for the diagnosis of equipment faults.

Conclusion

The daily maintenance of the filament dryer is very important for the normal operation and extended service life of the equipment. Through daily inspection, regular cleaning, lubrication, control system inspection and maintenance records, the performance and service life of the dryer can be effectively improved. In actual operation, the maintenance and maintenance plan should be determined according to the specific model and use environment of the equipment to ensure the safe and stable operation of the equipment.
