Safety requirements for vacuum drum filters
1. When the system is in normal operation, its granulated water volume, purge air volume, sweeping water volume, granulator maximum water temperature and slag flow rate shall meet the design specifications.
2. When the system is running, the equipment inspection should meet the following requirements: no abnormality in equipment inspection, no clogging of the granulating head, no slag block in the trough grille, reasonable high and low ditch and slag gate, no slag in the hot water tank, and pit in the pit There is no water and slag, no leaks in each pipeline valve, the tape transportation is stable, no deviation, and the water level of the accident is normal.
3. The slag ditch used in tapping shall have the conditions for diverting the dry slag or other measures for treating the slag. The time for diverting the shunt shall not exceed 3 min.
4. During normal production, the operation of system equipment should be automatically controlled.
