Function:
The soiled cooling lubricant is conveyed onto the non-woven filter lying in a cavity, via a liquid feed distributor. Owing to the gravitational force the coolant flows through the non-woven filter into a liquid container beneath the band filter.
The dirt particles contained in the cooling lubricant are filtered out by the non-woven filter and accumulate in the form of a sludge cake on it. This causes a reduction of the permeability of the filter paper and, therefore, an increase of the liquid level above the filter cavity.
As the liquid level increases, an adjustable float-type switch controls the continuous transport of the non-woven filter driven by an electric motor.
This way, non-woven filter clogged with dirt particles is discharged automatically driven by the quantity and permeability of the dirt accumulations.
