Solid Liquid Vertical Pressure Leaf Filter 0.4MPA Industrial
Filtration Leaf Separator Filter
High Performance Vertical Pressure Leaf Filter for Industrial
Filtration Needs
Working Principle
The vertical pressure leaf filter operates by pumping filtrate into
the tank through the liquid inlet pipe. Under pressure, solid
impurities are intercepted by the filter screen, forming a filter
cake while clear filtrate passes through the screen into the outlet
pipe. As filtration continues, the filter cake thickness increases,
raising internal pressure. When pressure reaches approximately
0.4MPa, filtration stops and compressed air is introduced to dry
the filter cake. The vibrator then shakes off the dried cake for
discharge through the slag outlet.
Filter Slag Discharge Process
As filtration volume increases and filter cake thickens, pressure
rises within the tank. When the pressure gauge indicates 0.4MPa,
the bleaching earth mixture feed is stopped. Compressed air is then
introduced through the overflow port, pressing residual oil from
the filter cake back to the decolorizing pot. After approximately
30 minutes of drying, air input ceases. When pressure returns to
zero, the butterfly valve opens and the vibrator activates to
discharge the slag, completing the filtration cycle.
