Automatic Overhead Filter Press

Automatic Overhead Filter Press is a type of filtration equipment used in various industries to separate solids from liquids. This technology is widely employed in water treatment, mining, chemical, and food industries. Here is an explanation of the components and working principles of the Filter Press:

Main Components

1. Frame: The structure that supports the entire filter press components. It consists of two main parts: the fixed head and the moving head.
2. Platen: Plates that act as support and press the filter plates.
3. Filter Plate: Plates placed in a row between the fixed head and the moving head. The filter plate has chambers where the slurry (solid-liquid mixture) is placed and separated.
4. Filter Cloth: Fabric that covers the filter plate and serves as the filtration medium.
5. Hydraulic System: The hydraulic system moves the moving head to press and open the row of filter plates.
6. Overhead Beam: A structure that hangs above the filter plates and supports the automatic opening system.

Working Principles

1. Filling: Slurry is pumped into the filter press through the inlet. The liquid flows through the filter cloth, leaving solids that accumulate inside the filter plate chambers.
2. Filtration: As the pressure inside the chamber increases, the liquid passes through the filter cloth and exits through the outlet as clean filtrate. The remaining solids form a cake on the filter cloth.
3. Compression: After filtration, the hydraulic system presses the filter plates tighter to squeeze out any remaining liquid from the cake.
4. Cake Discharge: After the compression process, the moving head is retracted by the hydraulic system, opening the space between the filter plates. The automatic overhead beam system helps pull the filter plates one by one, allowing the cake to fall due to gravity or with the aid of a vibration system.
5. Washing: In some applications, the filter press is equipped with a washing system to clean the cake or filter cloth between cycles.

Advantages

1. Full Automation: Reduces the need for manual labor and increases operational efficiency.
2. Efficient Filtration: Can handle large volumes of slurry and produce cakes with low moisture content.
3. Easy Maintenance: Modular design allows for easy maintenance and component replacement.
4. Consistent Results: Provides consistent filtration results with minimal variation between cycles.

Applications

• Wastewater Treatment: Separates solids from water to produce cleaner water before disposal or reuse.
• Mining Industry: Processes tailings to separate valuable minerals from waste.
• Chemical Industry: Purifies products or raw materials from solid contaminants.
• Food and Beverage Industry: Separates solid particles from liquids to produce cleaner and purer products.
