Introduction

The plate and frame filter press is a robust and versatile technology used for solid-liquid separation in various industries, including chemical, pharmaceutical, and food processing. This article provides a detailed understanding of its operation, components, and performance, alongside solutions offered by Jinrun Filter Press Company.

Basic Principles of Plate and Frame Filter Press

The core principle behind a plate and frame filter press is to apply pressure to a slurry, forcing the liquid through a filtration medium, leaving behind solids. The filtration is typically achieved through a series of plates and frames, creating chambers where the slurry is compressed.

Working Mechanism

Components

A typical plate and frame filter press consists of the following components:

  • Filter Plates and Frames: Alternating plates and frames hold the filter media and form the chambers.
  • Filter Cloth: Placed over each plate, it acts as a filtration medium.
  • Hydraulic System: Provides the pressure needed for the filtration process.
  • Piping and Valves: Control the flow of slurry and filtrate.

Operation Cycle

The operation cycle of a plate and frame filter press includes several stages:

  1. Slurry Feeding: The slurry is pumped into the press at a pressure ranging from 4 to 15 bar, typically. The specific pressure depends on the material being filtered.
  2. Filtration: As the slurry fills the chambers, the liquid passes through the filter cloth, while the solids accumulate on the plates. Filtration rates can achieve up to 1000 liters per hour per square meter of filter area.
  3. Plate Shaking or Washing (Optional): Ensures that any remaining solids are dislodged from the cloth, enhancing the efficiency of the process.
  4. Cake Discharge: Once filtration is complete, the hydraulic system releases the pressure, allowing the plates to separate for cake removal.
  5. Cleaning and Reassembly: The filter cloth and plates are cleaned before the press is reassembled for another cycle.

Performance Characteristics

The performance of a plate and frame filter press is influenced by several parameters:

  • Filtrate Clarity: Achieved through optimal selection of filter cloth and operating pressure, typically yielding clarity levels down to 5 microns.
  • Filter Cake Moisture Content: Generally ranges between 20% to 70%, depending on the material and operational parameters.
  • Throughput and Efficiency: High throughput is achieved with shorter cycle times due to efficient slurry handling and cake removal.
