Spray granulation dryer is an important part of the production process. Maintaining the normal operation of the equipment is a necessary condition to ensure the stability of PTC production. Regular cleaning, maintenance and maintenance help to identify problems in a timely manner, resolve potential failures, reduce downtime, and ensure normal production stability. Proper maintenance can also extend the life of your equipment.
If the equipment is operated for a long time or due to improper operation, aggregates will appear in some equipments and affect normal operation. At this time, it is necessary to stop working for cleaning. For the cleaning of the aggregate in the drying tower, open the cleaning door, sweep the funnel-shaped bottom aggregate with a long broom, open the discharge valve, and rinse the tower with tap water. To remove the dust in the cyclone, it is also necessary to open the cyclone, sweep the aggregate with a broom, and rinse with water if necessary. For the cleaning of the bag filter, open the control switch, tap continuously, then open the cleaning door, hit the bag filter, and replace the filter bag after the Zui. For the cleaning of the slurry pipeline system, the sewage valve of the two-way filter should be opened, the filter screen and the pipeline should be cleaned, and then the material pump should be opened to replace the pump tube, the pressure regulation package and the pipeline with water. After a period of operation, the spray granulation dryer needs to be inspected and cured as necessary. For the feeding system, check the filter, pipe, valve, nozzle, etc. to see if there is any blockage, regular cleaning, check the nozzle wear condition for timely replacement. The material pump should be checked for oil leakage, whether the pressure is normal, and whether the oil level is normal. For the fan, check whether the shaft and the bearing are short of oil and heat, whether there is vibration, noise, etc. If necessary, clean the blades and balance the blades. For the heater, check whether the heat pipe is normal, and if necessary, clean the filter of the oil pipe, oil pump and grease nipple. In addition, you should also pay attention to whether the motor has heat, vibration, abnormal sound, etc., whether the instrument and electrical appliances of the control cabinet work normally.
In addition, when the equipment is running for about 2400 hours (generally during the shutdown period), the equipment must be partially disassembled and maintained by the maintenance personnel.
