Daily operation of spray granulation drier

Main products: drying equipment, mixing dryer, spray granulation dryer, vibratory fluidized bed dryer, air flash dryer, belt dryer, spray granulation dryer, daily operation: 1 In daily production process, the necessary preparatory work should be made before starting the spray granulation drier First of all, check whether the connection of bearing and sealing part of each device is loose, whether the lubricating oil condition of each mechanical part and the valve port of each water, air and slurry pipe are in the required position Then turn on the power supply to check whether the voltage and instrument are normal After Zui, check the quantity and concentration of slurry in the slurry mixing drum If there is any problem, it should be eliminated in time 2 Then turn on the forced draft fan and exhaust fan in turn, and then turn on the heating switch to start heating When the outlet temperature reaches the set temperature (generally about 130 ℃), start the feed pump and dust removal system When the pump pressure reaches 2MPa, open the spray gun and start granulation After the operation of the equipment, the atomization and the working condition of the feed pump shall be observed in time If the gun is blocked, the nozzle shall be cleaned or replaced immediately After the normal operation of the spray granulation drier, it should also regularly collect and check the operation of each system regularly, record the technological parameters, and pay attention to clearing the vibration filter screen 3 At the end of granulation, the heating device shall be shut down first and the gas turbine shall be stopped Then close the spray gun valve, replace the spray gun, screw off the spray nozzle and wash it When the inlet temperature drops below 100 ℃, the operation of forced draft fan and exhaust fan can be stopped Then clean up the residual materials in the drying tower and dust remover, close the dust remover and air hammer, turn off the main power supply after Zui, and complete the production operation 4 In case of emergency, the equipment must be shut down immediately, and the blower and feed pump shall be shut down first In case of power failure, the gas turbine shall be pulled out to cool the tower naturally, and then the blowdown valve shall be opened to drain the slurry in the slurry pipeline and clean the equipment.
