In the daily production process, the necessary preparations should be carried out before starting the equipment. Check whether the joints of the bearings and sealing parts of each device are loose, the lubricating oil condition of each mechanical part, and whether the valve ports of each water, air, and slurry pipe are in the required positions.
Then turn on the power to check whether the voltage and meter are normal, and then check the amount and concentration of the slurry in the slurry mixing tank. If there is a problem, it should be eliminated in time. Then turn on the blower and exhaust fan in turn, and then turn on the heating switch to start heating. When the temperature of the discharge port reaches the set temperature (usually about 130 ℃), start the material pump and the dust removal system. When the pump pressure reaches 2MPa, open the spray gun and start granulation. After the equipment is running, the atomization situation and the working condition of the material pump should be observed in time. If the gun is blocked, the nozzle should be cleaned or replaced immediately. After the equipment is in normal operation, it should also receive materials regularly, check the operation of each system regularly, record various process parameters, and pay attention to cleaning the vibrating filter screen.
At the end of granulation, the heating device should be turned off, and the gas engine should be stopped. Then close the gun valve, replace the gun, unscrew the nozzle and rinse. When the inlet temperature is reduced to below 100 ℃, the operation of the blower and the exhaust fan can be stopped. Then clean the residual material in the drying tower and the dust collector, close the dust collector and the air hammer, and then turn off the main power supply to complete the production operation.
In case of emergency, shut down the equipment immediately, and shut down the blower and feed pump. In the event of a sudden power failure, the gas engine should be pulled out to cool the tower body naturally, and then the blowdown valve should be opened to drain the slurry in the slurry pipeline and clean the equipment.
