Automatic Plate Pulling Electric Hydraulic Automatic Pressure Maintaining Filter Press

High-Efficiency Fully Automatic Solid-Liquid Separation Equipment

The Automatic Plate Pulling Electric Hydraulic Automatic Pressure Maintaining Filter Press is an advanced solid-liquid separation system designed for high-efficiency sludge dewatering and industrial filtration. It integrates electric hydraulic pressing, automatic plate pulling, and automatic pressure maintaining functions to ensure stable operation, high filtration efficiency, and reduced labor cost.

This equipment is widely used in wastewater treatment plants, chemical industries, mining operations, metallurgy, ceramics, food processing, pharmaceutical production, electroplating wastewater treatment, and environmental protection projects. It is especially suitable for applications requiring continuous operation, high dewatering efficiency, and stable filtration performance.

Working Principle

The filter press operates by feeding slurry into closed filter chambers formed by filter plates. Under the action of an electric hydraulic system, the plates are tightly compressed to form a sealed filtration space.

During the feeding stage, solid particles are retained inside the chambers while liquid passes through the filter cloth and is discharged as filtrate. As the pressure increases, the system maintains a stable pressure automatically through the hydraulic pressure-maintaining unit, ensuring consistent filtration efficiency throughout the process.

After filtration is completed, the automatic plate pulling system sequentially separates the filter plates, allowing the filter cakes to be discharged automatically. This significantly reduces manual labor and improves overall production efficiency.
