An automatic scraper bottom discharging intermittent operation centrifuge is a filtering centrifuge that operates automatically.
The machine is controlled by a variable-frequency inverter, with adjustable separation factors. It features medium-speed feeding, high-speed separation, and low-speed unloading. After the machine starts and reaches the feeding speed, materials enter the drum through the upper feeding tube for separation. Depending on the material process, after cleaning and dewatering, the speed is reduced for unloading, with solid phase materials discharged from the bottom. Unloading is done with a narrow scraper, low-speed sealed unloading, resulting in minimal grain breakage. Feeding and washing are controlled by pipes and valves. The machine's operation is controlled by a programmable logic controller (PLC), with automatic operation for feeding, preliminary filtration, fine filtration, and scraping. The scraper system can be hydraulically, pneumatically, or electrically driven. The control cabinet can be operated on-site or remotely.
