Filtration is an important part of many industrial processes from chemical production to food and beverage manufacturing. Filter plates provide a versatile and economical method for liquid filtration.
What is a Filter Plate?
A filter plate is a flat plate with small holes or perforations in it. Multiple filter plates are stacked together with filter media in between to create a filter assembly. Filter plates help support the filter media and provide a direct path for liquid flow.
How Do Filter Plates Work?
Liquid enters the filter assembly through the inlet and passes through the holes in the first filter plate. It then encounters the filter media which traps particles and contaminants larger than its pore size. The filtered liquid flows through subsequent filter plates and exits through the outlet.
Main Benefits Of Filter Plates By China Filter Plate Supplier
- Plate hole or slot size determines the maximum particle size that can be filtered. Typical hole diameters range from 0.5 mm to 5 mm. Slot widths range from 0.5 to 3 mm.
- Hole spacing affects the flow rate and dirt holding capacity. Closer spacing provides more surface area but higher flow resistance.
- Filter plates need to be compatible with the chemicals and pH levels of the liquid being filtered to prevent corrosion and plate degradation.
- Plates can often be cleaned and reused, but may eventually need replacement due to damage or deterioration of the plate material.
Common Types of Filter Plates
- Perforated Plates: These have small holes punched through the plate material. They are low cost but provide lower dirt holding capacity.
- Screen Plates: Metal screen mesh is sometimes used as a filter plate material for specialty applications.
- Perforated Plates: These have small holes punched through the plate material. They are low cost but provide lower dirt holding capacity.
- China Filter Plate: Plates manufactured in China are increasingly common due to lower costs. Both perforated and slotted filter plates can be sourced from Chinese suppliers.
Leading China Filter Plate Supplier Tell Key Considerations
Factors to consider when choosing filter plates include plate material, hole or slot size, spacing between holes, and flow rates needed. Filter plate material typically matches the vessel material for compatibility.
