Durable, High-Performance FRP Filter Presses
$8,500.00
Our high-performance diaphragm filter press is a top-tier solid-liquid separation solution for global industries. Integrating mechanical, electrical and hydraulic technologies, it features PLC automatic control for seamless operation from pressing to discharging, enabling unmanned monitoring.
Crafted with reinforced polypropylene filter plates and premium elastic diaphragms, it achieves deep dehydration through secondary high-pressure squeezing, reducing cake moisture content to as low as 15%. The equipment boasts excellent corrosion resistance (pH 2-12) and energy efficiency, saving 30%-50% water in washing processes.
描述
Durable, High-Performance FRP Filter Presses for Industrial Sludge Treatment
A diaphragm filter press is a type of filter press equipped with elastic diaphragms installed between the filter plates and the filter cloths. During operation, once the feeding process is completed, high-pressure fluid or gas can be injected into the diaphragm plates. This causes the entire diaphragm to expand and compress the filter cake, thereby achieving further dewatering—a process commonly referred to as squeeze filtration.
A diaphragm filter press is a solid-liquid separation device that utilizes an elastic diaphragm to perform secondary squeezing of the filter cake, primarily used in industries such as chemical, environmental protection, pharmaceutical, and food processing. By incorporating diaphragm technology into the filter plates, it significantly enhances the solid dryness. Compared to traditional filtration processes, it achieves the lowest residual moisture content in the filter cake, making it one of the most robust and widely applied systems. Special materials such as PVDF are also available for specific requirements.
The working principle involves adding an elastic membrane between the filter plates and the filter cloth of a standard filter press. After the filter chamber completes feeding, high-pressure fluid or gas is injected into the diaphragm, causing it to expand and compress the filter cake. This further squeezes liquid out of the filter cake, significantly reducing its moisture content.

Features
1. Unmatched Cycle Efficiency: Achieves a complete “feed-discharge-wash” cycle in just 30 minutes — significantly faster than conventional presses. This is enabled by one-step automatic plate pulling for faster discharge and a fully integrated one-time cloth washing system.
2. Superior Cake Dryness (Optional): Equip with a membrane expression system powered by high-pressure air. This ensures exceptional sealing and higher expression pressure, resulting in significantly lower residual cake moisture content.
3. Modular & Service-Friendly Design: Built with a modular structure, allowing for easy disassembly and reassembly. This simplifies maintenance, part replacement, and potential future upgrades.
4. Integrated Mechatronic Design: Employs an advanced mechatronics-hydraulics-integrated modeling design. The frame and system configuration are optimally engineered based on the number of filter plates, offering tailored filter areas and chamber volumes.
5. Comprehensive Automation: The system fully automates the entire process cycle: starting/stopping the feed pump, pressing, feeding, pressurizing, expressing, cake blowing, plate pulling, pausing, and cake discharge with conveyor control. Note: This sequence is fully customizable to your specific process requirements.

Advantages of diaphragm filter press
1.High Solid-Liquid Separation Efficiency: Through secondary pressing, the moisture content of the filter cake is significantly reduced, resulting in improved separation effectiveness.
2.High Level of Automation: Many units are equipped with programmable control systems, enabling fully automated operations including feeding, filtration, pressing, and cake discharge.
3.Flexible Operation: The degree of compression can be adjusted by controlling the pressure and duration of diaphragm inflation to suit different material requirements.
4.Wide Range of Applications: Widely utilized in industries requiring efficient solid-liquid separation and low filter cake moisture, such as chemical processing, metallurgy, mining, food processing, and wastewater treatment.
5.Customization options are available to tailor the filter press to meet specific process requirements.
