FILTER PLATES
Overview: N M Patel & Co. offers a wide range of Filter Plates, which are essential components in filter presses. Our filter plates are designed for durability and optimal performance in various filtration applications.
Key Features:
– Material Variety: Available in polypropylene, stainless steel, and other materials.
– Design Options: Chamber, membrane, and plate & frame designs.
– High Durability: Engineered to withstand rigorous use.
– Customizable: Tailored to meet specific application requirements.
– Efficient Filtration: Ensures high filtration efficiency and effective solid-liquid separation.
Filter Plates & Their Different Variations
Filter cake thicknesses and filter plate thicknesses are freely configurable depending on the application and filtration conditions. The plate formats vary from 250mm x 250mm up to 2000mm x 2000mm with a cake thickness of 10mm up to 55mm and thus allow an optimal adaptation to the filtration tasks. In this context, we offer a variety of inlet types and plate designs with chamber or membrane technology for older as well as newer makes and third-party systems. Depending on the application, the inlet positions are located in the upper corner, in the center, or on the upper side of the filter plate.
Filter press plates with membrane technology allow mechanical squeezing of the filter cake after the actual filtration process, which results in a higher dry matter content. These filter press plates are available either with permanently integrated membranes or with replaceable membranes on request.
Chamber filter press plates and membrane filter press plates can also be supplied in gas-tight & drip-tight designs (CGR). Depending on customer requirements, filter press plates can be individually designed and retrofitted to any existing and commissioned filter press.
Filter presses from N.M Patel Filter Presses meet the specific requirements of different applications and industries by equipping each filter press with the appropriate filter plates.
Standard sizes – 250mm x 250mm, 310mm x 310mm, 350mm x 350mm, 410mm x 410mm, 470mm x 470mm, 500mm x 500mm, 610mm x 610mm, 800mm x 800mm, 915mm x 915mm, 1000mm x 1000mm, 1060mm x 1060mm, 1200mm x 1200mm, 1500mm x 1500mm, 1500mm x 2000mm, 2000mm x 2000mm.
Recessed Chamber
This is the most common type of filter plate. The filter cloth is hung or draped over the filter plate. Filtration takes place as filtrate passes through the cloth and drains out through the raised pips to the corner discharge holes.
• Standard web thickness (For 100 or 225 psi, maximum feed pressure)
• Available in Polypropylene for standard operations
• Durco-Temp™ high-temperature thermoplastic for high temp application
Caulked and Gasketted
Designed to prevent leaking during the filtration cycle.
Plates have a caulking groove just outside the recessed portion of the plate, and cloths have a rope sewn in the edge that is inserted in the caulking groove.
A second groove is provided in the perimeter sealing surface on one side of each plate and the gasket fits in this groove to contact the adjacent plate and prevent slurry leakage across the sealing surface.
Another circular groove on one side of each plate surrounds each corner eye and a gasket fits in each corner eye groove to prevent leakage across the sealing surface.
Corner Feed
Used when solid in the slurry stream has a high specific gravity.
Allows filter chambers to be filled completely when heavy slurries are dewatered.
Membrane
The filter plate has three layers: a central web or support. Thin membranes are on either side.
Filtration takes place the same as with a recessed chamber plate.
When the cycle is finished, the spaces between the web and membranes are inflated with air or water. This squeezes the cake between the plates resulting in dryer cake.
Often, membrane plates are mixed with companion non-membrane plates. Referred to as “Mixed Pack”.
Cast Iron & Aluminium
Metal Plates in cast iron, stainless steel, aluminum, or other materials are used for higher temperatures or other unique applications.
