If the spray dryer is running for a long time or due to improper operation, aggregates will appear in some spray granulation dryers and affect normal operation. At this time, it is necessary to stop work for cleaning. For the cleaning of aggregates in the drying tower, the cleaning door should be opened and used Use a long broom to sweep the bottom of the funnel and open the discharge valve. When the freezer is turned on, the circulating water must be turned on, and the boiling granulating dryer tower must be rinsed with tap water.
After about 600 hours of operation, the spray dryer needs to be inspected and maintained as necessary to enter the boiling granulating dryer. For the feeding system, check the filters, pipes, valves, nozzles, etc. to see if they are blocked, clean them regularly, and check the nozzle wear of the boiling granulating dryer so that it can be replaced when the boiling granulating dryer.
After about 600 hours of operation, check whether the feed pump is leaking, whether the pressure is normal, whether the oil level is normal, etc. For the fan of the boiling dryer, check whether the shaft and bearing are lack of oil to generate heat, whether there is vibration, noise, etc., and if necessary, clean the three filters of the oil pipe, oil pump, and oil nozzle.
In case of emergency, the equipment must be shut down immediately, and the blower and material pump should be shut down first. If there is a sudden power failure, pull out the gas engine to cool the tower naturally, then open the drain valve, drain the slurry in the slurry pipeline, and clean the equipment.
