Hydraulic closing mechanical pressure holding filter press

Description

Hydraulic closing mechanical pressure holding filter press is a system used in filter presses to close and compress filter plates using hydraulic pressure and then maintain that pressure using a mechanical holding mechanism. This system is designed to ensure that the filtration pressure remains constant throughout the filtration process without requiring continuous hydraulic energy. Here is a detailed explanation of the components and working principles of this system:

Main Components

1. Hydraulic System: This system uses hydraulic fluid to generate the pressure needed to compress the filter plates together. It includes components such as a hydraulic pump, hydraulic cylinders, and controllers.
2. Mechanical Pressure Holding Mechanism: After the hydraulic pressure is applied and the filter plates are tightly pressed together, this mechanism locks the position of the filter plates to maintain the pressure without needing further hydraulic pressure. This typically consists of mechanical locks or other locking systems that can be engaged once the optimal pressure is reached.

Working Principles

1. Hydraulic Closing:
   • Initiation: The process begins with filling the slurry (solid-liquid mixture) into the chambers between the filter plates.
   • Compression: The hydraulic pump is activated to pump hydraulic fluid into the hydraulic cylinders. This pressure moves the moving head, pressing the filter plates together.
   • Achieving Pressure: Once the filter plates are tightly compressed and the desired pressure is reached, the hydraulic system maintains this pressure for a short period to ensure effective slurry filtration.
2. Mechanical Pressure Holding:
   • Mechanical Locking: After the desired hydraulic pressure is achieved, the mechanical pressure holding mechanism is engaged. This mechanism locks the filter plates in the compressed position.
   • Pressure Maintenance: With the mechanical mechanism holding the position, the pressure can be maintained without the need for continuous energy from the hydraulic system. This means the hydraulic pump can be turned off or reduced, saving energy.
   • Filtration Process: With the pressure maintained by the mechanical mechanism, the filtration process occurs. The liquid passes through the filter cloth and exits as clean filtrate, while solids remain in the chambers of the filter plates, forming a cake.

Advantages

1. Energy Efficiency: Using a mechanical mechanism to maintain pressure reduces the need for continuous hydraulic energy.
2. Pressure Stability: Ensures that the filtration pressure remains constant throughout the process, which is crucial for the quality of the filtration results.
3. Operational Reliability: The combination of hydraulic and mechanical systems provides reliable and durable operation.
4. Reduced Operational Costs: Lowers energy consumption and minimizes wear and tear on hydraulic components.
