Introduction – Filter Plates Are One Of The Most Vital Components
Filter plates are one of the most vital components in industrial filtration systems. They hold and support the filter media through which the target liquids pass through. Filter plates contain structures that facilitate controlled flow while removing impurities through different filtration mechanisms. In this blog, we will look at what filter plates are made of, their design features, manufacturing process, quality considerations, and the importance of sourcing them from expert filter plate factories.
What Are Filter Plates Made of?
Filter plates are manufactured from materials like polypropylene, polyvinyl chloride, stainless steel, titanium, and fibreglass reinforced plastics. The material is selected based on properties like chemical compatibility, temperature resistance, durability, and ease of fabrication. For instance, polypropylene suits both acidic and alkaline solutions but has low temperature resistance. Stainless steel handles high pressures and temperatures, but is difficult to fabricate and machine.
Key Design Aspects Of Filter Plates
Some key design aspects in filter plates are:
- Channel and gasket grooves to hold the filter media and seal between adjoining plates.
- Perforations or mesh structures that support the media while allowing uniform flow across the plate surface area. The hole size and pattern geometry impacts filtration efficiency.
- Inlet and outlet ports with pipe connections to direct flow in and out of the filter press.
- Surface finishes to facilitate cleaning and prevent particle adhesion.
- Structural ribs and frames to provide sufficient strength and rigidity.
The plate design is optimized based on the type of filter media, operating pressures, filtration accuracy needed, and throughput capacities.
Manufacturing Process For Filter Plates
- Filter plates are manufactured through methods like laser cutting, CNC machining, injection moulding and metal forming processes.
- Laser cutting can precisely cut plates of consistent quality out of sheet material. It is suited for softer materials like plastics.
- CNC machining is used to machine plates from metal blocks for high precision and complex 3D shapes.
- Plastic injection moulding involves melting plastic and injecting it into a mould cavity. It is ideal for mass production of plastic plates.
- Metal forming like deep drawing can shape sheets into plates of various profiles through stamping dies.
Stringent dimensional tolerances, sanitary welding standards, and consistent surface finishes must be maintained to get defect-free and long-lasting filter plates. The production expertise of the filter plate manufacturer is crucial.
Critical Quality Considerations For Filter Plates
Filter plates must adhere to high quality standards to prevent premature failures. Some key parameters are:
- Dimensions within tight tolerances for proper sealing and alignment.
- Smooth finishes without nicks or cracks that can trap contaminants.
- Non-brittle and non-deforming material that can withstand operating pressures.
- Non-reactive material that does not degrade or contaminate the filtered liquids.
- Durable plates that can withstand repetitive washing, soaking and drying cycles.
- Structural stability to support filter media throughout its service lifespan.
