Maximize Throughput, Minimize Cycles: The Quick Opening Filter Press

Q: How much time can I actually save per cycle compared to a standard press?

A standard filter press shifts plates one by one, which can take 20-40 minutes for a large 1500mm machine. The Loway Quick Opening Press discharges the entire pack in 3-5 minutes. For a plant running 10 cycles a day, this saves over 4 hours of production time daily, essentially giving you half a shift of extra capacity.

Q: Does the fast-opening system consume more electricity?

While the hydraulic station motor is slightly more powerful to drive the rapid movement, the total energy cost per ton of sludge is actually lower. Because the machine spends less time idling and more time filtering, your overall plant efficiency increases.

Q: These machines are long. How are they shipped and installed?

Quick opening presses typically have longer beams. For export, we use a Split-Beam design with flange connections to fit inside standard 40HQ containers. We provide detailed re-assembly guides and video tutorials. The modular design ensures that on-site assembly is straightforward and structural integrity is not compromised.

Q: What is the maximum number of plates supported by the Quick Opening system?

To ensure mechanical stability, we typically limit the Quick Opening system to approximately 80-100 chambers depending on plate size. For larger filtration areas, we recommend using two medium-sized units instead of a single oversized press, or consulting our engineers for a custom multi-cylinder design.

Q: Does the fast-opening chain mechanism require frequent maintenance?

No. We use High-Tensile Alloy Steel Chains engineered for heavy loads. Combined with our automatic lubrication system, the mechanism requires minimal maintenance. Routine visual inspection is typically sufficient.

Q: Can this press handle sticky sludge that doesn't fall off easily?

Yes. This is exactly why the machine includes the Automatic Vibration System. The vibration energy breaks the bond between the cake and the cloth to ensure clean discharge even for sticky chemical or biological sludges.

Q: What is the difference between Group Opening and All Opening?

All Opening pulls all plates apart at once, which is ideal for smaller presses or very dry cakes. Group Opening pulls sets of 3-5 plates and is better for larger presses to manage hydraulic load. Our engineers will recommend the best method based on your press size.

Engineered for high-tonnage industries like Mining and Sand Washing. Loway’s proprietary Multi-Plate Opening System reduces discharge time by up to 75%, delivering continuous dewatering performance for large-scale operations.

Key Performance Indicators:

Cycle Efficiency: Discharges 3-6x faster than standard presses.
System Pressure: High-pressure feeding up to 2.5 MPa.
Automation: Fully unmanned PLC control with Cake Vibration assist.

Redefining Efficiency for Large-Scale Dewatering

In heavy industries like Mining Tailings and Municipal Wastewater, traditional filter presses create a bottleneck. Opening plates one by one wastes valuable production time.

The Loway Quick Opening Filter Press is the solution. By replacing the standard shifter with a robust Mechanical Linkage or Hydraulic Chain System, our machines open multiple plates (groups of 3, 5, or the entire pack) simultaneously. This innovation transforms a 30-minute discharge cycle into a 3-minute rapid operation, significantly boosting your daily solids handling capacity without increasing your footprint.

How the Quick Opening system optimizes your production cycle

The high-powered hydraulic cylinder extends, pushing the head plate to compress the plate pack tightly. The system creates a robust seal capable of withstanding feed pressures up to 2.5 MPa.

Slurry is pumped into the chambers. As the filtrate passes through the cloth, solids accumulate to form a compact cake.

Note: Our optimized chamber design ensures uniform cake formation even at high flow rates.

For maximum dryness, high-pressure water/air inflates the membrane plates to squeeze the cake, followed by an air blow cycle to remove residual moisture from the capillaries.

Here is where time is saved. Instead of shifting plates one by one, the Mechanical Linkage System pulls the plates open in groups (or all at once).

Result: The entire pack opens in seconds, not minutes.

As the plates open, the Eccentric Vibration Motors automatically activate. This shakes the filter cloth bars, ensuring even the stickiest cakes fall off immediately, clearing the chamber for the next cycle instantly.

Engineered for Speed and Reliability

Fast-Opening Mechanism (The Engine of Speed)

Design: Plates are connected via high-tensile steel chains or rigid linkage bars.
Action: A high-torque hydraulic cylinder pulls the plate pack apart in groups (e.g., 3-5 plates at a time) or all at once.
Benefit: Dramatically reduces non-operational downtime. Ideal for processes requiring short filtration cycles.

Automatic Cake Vibration System (The Solution for Sticky Sludge)

Design: Eccentric vibration motors are integrated into the opening beam.
Action: Once the plates open, the system vibrates the filter cloth bar.
Benefit: Ensures 100% cake discharge even for sticky or viscous sludges, eliminating the need for operators to manually poke or clean the plates.

Reinforced "Dynamic Load" Structure

Design: Fast movement creates kinetic stress. We use Q345B Solid Carbon Steel for the main beam and extra-thick side bars.
Benefit: Provides the structural rigidity needed to withstand rapid open/close cycles 24/7 without fatigue or deformation.

Intelligent Unmanned Operation

Controlled by a premium Siemens/Schneider PLC, the system manages the entire dewatering lifecycle:

Auto-Pressure: Maintains optimal hydraulic seal during high-pressure feeding.
Auto-Fast Open: Triggers the multi-plate opening sequence.
Auto-Vibration: Activates vibration sequences to clear cakes.
Auto-Cloth Washing: (Optional) High-pressure spray bars clean cloths between cycles.

Result: One operator can easily manage 4-5 Loway Quick Opening Presses from a central control room.
