Plate And Frame Filter Press

• High Efficiency
  Plate and frame filter press can complete the filtration and solid-liquid separation process in a relatively short time, thereby improving production efficiency.
• Easy Operation
  Operating the plate and frame filter press is relatively simple, requiring only basic settings and controls to achieve automated filtration operations.
• Wide Applicability
  Plate and frame filter press is suitable for various solid-liquid separation processes and can handle different types of suspensions, such as wastewater treatment in chemical, food, pharmaceutical industries, and filtration of solid particles, etc.
• Good Filtration Effect
  Plate and frame filter press uses multiple layers of filter plates and filter cloths for filtration, resulting in a good filtration effect and achieving high solid-liquid separation efficiency.
• Energy Saving and Environmental Protection
  Compared to other solid-liquid separation equipment, plate and frame filter press consumes less energy during operation, reducing energy costs, and also reducing waste and pollutant emissions, meeting energy-saving and environmental protection requirements.
• Low Maintenance Cost
  Plate and frame filter press has relatively low maintenance costs, usually only requiring regular cleaning and replacement of consumable parts such as filter cloths, making maintenance relatively simple.
• High Operational Flexibility
  Plate and frame filter press can be adjusted and optimized according to different process requirements, with high operational flexibility to meet the needs of different production scenarios.

Plate and Frame Filter Press Structure

The plate and frame filter press is a kind of separation equipment widely used in industrial production. Its main structure and components are as follows:

• Filter Plates: These are the main components of the filter press. They are flat, rectangular plates with a central hole, often with filter cloths attached.
• Filter Frames: Frames surround the filter plates and provide support. They also have a central hole that aligns with the hole in the filter plates.
• Hydraulic System: Many modern plate and frame filter presses use a hydraulic system to apply pressure to the plates, squeezing the filter cake between them for better filtration.
• Feed Inlet: The slurry or suspension to be filtered is pumped into the filter press through a feed inlet.
• Filtrate Outlet: The liquid filtrate passes through the filter cloth and filter plates and exits the press through a filtrate outlet.
• Cake Discharge: Once the filtration process is complete, the solid cake formed between the plates is removed manually or using automated cake discharge systems.

Plate and Frame Filter Press Working Principle

The working principle of plate and frame filter press mainly includes the following steps:

1. Filling: The slurry or suspension is pumped into the filter press through the feed inlet. The filter press is initially open, allowing the slurry to flow into the space between the filter plates.
2. Filtration: Once the filter press is filled, it is closed by applying hydraulic pressure. This pressure pushes the filter plates and frames together, compressing the slurry and forcing the liquid component to pass through the filter cloth while retaining the solid particles as a cake.
3. Dewatering: As the filtrate passes through the filter cloth, the solid particles accumulate on the surface, forming a cake. The hydraulic pressure is maintained for a certain period to ensure thorough dewatering.
4. Cake Discharge: After dewatering, the filter press is opened, and the solid cake is removed from between the filter plates. This can be done manually or using automated systems, depending on the design of the filter press.
5. Rinse and Repeat: The process is repeated for the next slurry batch, with the filter press being cleaned if necessary between cycles.

Overall, the plate and frame filter press applies pressure to a slurry or suspension to separate the solid particles from the liquid component, resulting in a dewatered solid cake and a clarified liquid filtrate.
