Scraper Discharge Vacuum Drum Filter
A Scraper Discharge Vacuum Drum Filter is an industrial filtration device used to separate solids from liquids in slurry mixtures. Here’s a brief overview of how it works:
-
Vacuum Creation: The drum filter is partially submerged in a slurry mixture and rotates. A vacuum is created inside the drum, which draws the liquid through the filter medium on the drum's surface.
-
Filtration: As the drum rotates, the liquid passes through the filter medium, leaving the solids behind on the surface, forming a filter cake.
-
Scraper Discharge: A scraper blade is positioned against the drum surface. As the drum rotates out of the slurry, the scraper removes the accumulated filter cake from the drum.
-
Discharge and Collection: The scraped solids are discharged into a collection trough, while the filtered liquid (filtrate) is collected separately.
This type of filter is used in various industries, including chemical processing, food and beverage production, pharmaceuticals, and wastewater treatment, where efficient solid-liquid separation is required.
