What is the Function of the Filter Press?

آپریل 16, 2025

A filter press plate is a machine that is primarily responsible for filtering solids from liquids. Filter presses and their plates are used in the industrial sector to separate solids from liquids. Filter presses and their plates are the main drivers of the solid-liquid separation process, thereby helping users improve efficiency and obtain higher quality products that are much needed in various industries. This article will discuss the filter plates, their structure, and how they enhance efficient filtration processes.

The role of filter press plates

Filter press plates are the main structural components of the filtration equipment, which provide space for the filter cloth and form chambers for the filtration process. These plates absorb liquid and help the filter cloth effectively retain solid particles. The liquid can be discharged through the outlet, while the particles are trapped in the channel. This process is widely used in the mining of precious minerals, the production of chemicals, sewage treatment, and the production of food.

The main functions of filter press plates

1. Solid-liquid separation: This function is performed by the filter plates that forcefully seal the filter chamber to ensure that there will be no leakage during operation. This ensures efficient formation of the solid cake and high recovery of the main material.

2. Robustness: Made from strong materials such as cast iron, stainless steel and polypropylene, the filter plates are able to withstand high pressures and harsh environments.

3. Precision Engineering: The surface of the filter press filter plates is specially designed to achieve the most effective seal when compressed. This seal is very tight and ensures rapid drainage of liquids while minimizing the risk of contamination.

4. Flexible Design: Various applications require different types of filter plates. Choices include recessed chamber filter plates, membrane filter plates and plate and frame designs. Each design has its own unique advantages.

Types of filter plates

1. PP filter plates

PP filter plates are made of polypropylene, which is very flexible. Its filter surface is designed with special flow channels to prevent clogging, ensuring smooth operation. These plates are CNC machined to maintain a flatness of less than 25 µm, ensuring excellent sealing and no leaks due to machine failure during production.

2. Chamber plates

Chamber plates are available in a variety of materials such as cast iron and stainless steel. Typically, they can handle a maximum feed pressure of 3 MPa. These plates are ideal for high temperature and high pressure areas due to their excellent airtightness and corrosion resistance. The plates are designed to provide short filtration cycles and low cake moisture content, resulting in high efficiency.

3. Membrane plates

Membrane plates take membrane filtration to the next level in terms of solid content management. In a two-stage process, different pressures can be applied for filtration and a final press. This setup not only increases cake dryness, but also significantly reduces energy consumption, making it the most efficient choice in the industrial sector.

Choosing the right filter plate

Undoubtedly, the most important thing for achieving the best filtration results is the choice of filter plate. Here are the things that anyone considering choosing a filter plate should pay attention to:

1. Slurry composition: Understand the nature of the slurry being filtered. Acidic or abrasive slurries may require specific materials that can withstand the harsh conditions.

2. Filtration capacity: The filtration volume and required pressure should match the plate design and material. This will ensure that the solid-liquid separation is not only smooth and efficient, but also that performance is not compromised.

3. Membrane plates Membrane plates take filtration to a new level by providing superior solid content control. They allow for a two-step process: low-pressure filtration and high-pressure extrusion. This approach improves cake dryness and reduces energy consumption, making it an excellent choice for industries seeking efficiency.
