Pressure Leaf Filters
Pressure Leaf Filter is a MS/ SS Vertical Vessel with Filter Leaves inside. This leaves are mounted vertically on a common manifold pipe, through which the filtered liquid flows out, on the top, the leaves are held by a vibrating shaft. A mechanical vibrator driven by electric motor / pneumatic vibrator is provided for vibrating the leaf shaft for cake discharge. Jacket for hot filtration can be offered it desired over flow, vent / steam / air charging, pressure gauge & safety value are provided on the top. The top cover is provided with devit arm mechanism for raising the lid for cleaning / removing the leaves. I bolts are provided for quick opening and closing of top lid. A mechanical jack is provided to lift the top for cleaning / removing the leaves. Lugs are provided for mounting the PLF.
The Filter Leaves filter on both sides and hence a large filteration area is obtained in a relatively small vessel. Our SS filter leaves for PLF are Rivetted with the following materials.
- Hollandar Mesh of SS316L, 24/110 — 2 Layers.
- SS 304 mesh of 8×8=22 swg. — 2 Layers.
- SS 304 mesh of 4×4=14 swg. — 1 Layers.
Functions of PLF
Niagara type pressure leaf filters are widely used in the world to separate / filter suspended solids, foreign matters, spent earths from liquids.
