Vertical Pressure Leaf Filters
It consist of a vertical MS / SS tank with filter elements leaves inside. The 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. Optionally spray nozzles can also be provided for wet cake discharge. Jacket for hot filtration can be offered if desired Over flow, vent steam air charging pressure gauge and safety valve 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. Bottom opening is a simple and economical manual swing type which gives 100% opening or optionally a pneumatically actuated butterfly valve which opens about the center axis and divides the bottom in 2 halves is provided.

Horizontal Pressure Leaf Filters
Horizontal PLF works on similar principle but the shell is horizontal & leaves are vertical on common manifold. The filter shell has 4 wheels & can be retractable by a hydraulic cylinder on a rail. Two hydraulic cylinders are provided one each for opening & closing the wedge lock mechanism between the shell & cover. A hydraulic power pack unit, Pressure gauge, vent / steam valves, panel board etc is provided. After the filtration & cake drying is over, the outer vessels is retracted, thus opening up the leaves for cake discharge,. During opening / cleaning no connections have to be removed as the cover with leaves remain in fixed position. Cake can either be discharged manually by rubber mallet or optionally pneumatic / mechanical vibration can be provided for dry cake discharge. Spray nozzles can be provided for wet cake discharge. Horizontal PLF is preferred for higher filtration area or when solid cake has to be removed manually in semidry condition & in short period.
