Notes
1) Knoll Rotating Vacuum Filtration System, 1999, Model
VRF 450
Liquid Flows Through the Inflow Chamber Into the Rotating
Vacuum Filter from a Lifting Pump. a Sieve Drum Is Arranged
Such That It Is Completely Immersed in the Liquid and Forms a
Vacuum Chamber
a Vacuum Pump Sucks the Liquid from the Inside of the Drum and
Conveys It to the Clean Tank. the Resulting Vacuum Causes
Liquid to Flow Into the Drum, Dirt Particles Are Retained by the
Sieve Drum Mesh.
Vacuum Pressure Increases Due to Dirt Particles (Filter Cake)
Deposited on the Fine Filter Mesh.
The Preset Subpressure Value Sets the Drum Rotating Via the
Drive Motor and the Chain.
The Sludge Cake Is Scraped off the Filter and the Filter Is
Rinsed by Reverse Flow.
Simultaneously, the Sludge Is Discharged Into a Sludge
Container by Means of a Scraper Chain.
The Lower Tank Is a Dirty Tank and the Upper Tank Is the Clean
Tank. There Is High Pressure (80 Gpm) and Lower Pressure Pumps
for Returning the Oil to the Equipment.
This Can Be Also Be Used to Receive the Oil from the Chip
Spinner and Store the Clean Oil Until Ready to Use.
Condition - Very Good
