Automatic Filter Press for Recycling and Recovery of Useful Materials

Core Components

Frame part:This includes the thrust plate, compression plate, and main beam, which form the basic structure of the equipment.

Filtering section: Composed of multiple filter plates, filter cloth and feed inlet, it is the core unit for achieving solid-liquid separation.

Hydraulic system: Composed of the hydraulic station, cylinders, oil pumps and control valves, it provides power.

Automatic plate-lifting system: It consists of a plate-lifting trolley, a transmission device, a variable-frequency motor and photoelectric sensors, which is responsible for

precisely and orderly lifting each filter plate.

Electrical control system: Utilizes PLC and touch screen, which is used for setting parameters, controlling processes and displaying faults.

Auxiliary devices (optional): liquid receiving tray, collecting tank, filter cloth cleaning device, belt conveyor, etc.

Key Product Advantages

High degree of automation, saving manpower: Full PLC control, simple and convenient.

High production efficiency: Automatic cycle operation, suitable for large-scale continuous or batch production.

Good filtration effect: Low moisture content of filter cake, stable and reliable filtration quality.

Safe and reliable operation: Equipped with multiple safety protection devices, smooth operation, low failure rate.

Customized products: Can be customized according to the material filtration situation.

Closed operation: Optional fully enclosed design to prevent material leakage and comply with environmental protection requirements.

Working principle and process

Core principle: Through “compression” and “filtration”, the slurry mixture is transformed into dry mud cake and clean water.

Work Flow:

Compression into a chamber: The hydraulic cylinder pushes all the filter plates tightly together, creating individual chambers (filter chambers) in the middle.

Pumping in filtration: Using a high-pressure pump, the slurry is pushed in. The water will flow out through the small holes in the filter cloth (turning into clear water), while the solid particles are retained. They accumulate more and more in the filter chamber, gradually compressing into thick “sludge cakes”.

Automatic unloading: After the filtration process is completed, the hydraulic cylinder releases, and an automatic mechanical hand (pulling plate device) will sequentially pull each filter plate apart. Once the filter plates are separated, the dry sludge cake inside will automatically fall down due to its own weight, completing the unloading.

The entire process is automatically controlled by PLC, which is equivalent to a “fully automatic giant sandwich cookie mold”. It squeezes out the moisture from the filling (mud water), and finally automatically opens to let the dry “cookies” (mud cake) fall out.

How to choose the right model?

1. What is the liquid that needs filtering?
   2. What is the flow rate?
   3. Temperature/PH value?
   4. What are the main solid impurities that need to be filtered from the liquid? What is their content?
