Quick Opening Filter Press Equipment
High-Efficiency Solid-Liquid Separation Equipment for Industrial Applications

The Quick-Opening Filter Press is an advanced solid-liquid separation system that integrates mechanical dewatering, hydraulic compression, and intelligent control. This equipment is specially engineered to address critical challenges found in traditional filter presses, including slow discharge cycles, high filter cake moisture content, and frequent maintenance downtime.
Loway Quick Opening Filter Press is a cutting-edge filtration system designed for rapid separation of solids and liquids in industrial processes. Thanks to its modular filter plate design, high-strength frame, automated hydraulic system, and intelligent PLC control, the quick-opening filter press achieves a 40% reduction in cycle time and a 30% increase in filter cake dryness. This makes it the preferred solution for high-volume applications in mining, chemical processing, environmental engineering, and wastewater treatment.

Operation Workflow
The quick-opening filter press operates in five key stages, each managed through intelligent automation for speed and accuracy.
1. Plate Closing & Pre-Compression
The hydraulic system rapidly pushes the compression plate, closing the plate set in 30–60 seconds (traditional models take 3–5 minutes).
Precision sensors ensure closure accuracy within ±1 mm, preventing cloth misalignment and leakage.
2. Feed and Filtration
Slurry enters the filter chambers at 0.4–0.8 MPa.
Solids are captured by the filter cloth, forming a cake, while filtrate exits through drainage channels.
Dual-feed design reduces feed time by 30%, enhancing overall throughput.
3. Membrane Squeeze (Optional)
Inflatable membranes expand at 1.2–2.0 MPa to compress the cake further.
Especially useful for high-moisture materials like sludge, reducing final cake moisture from 35% to 18%.
4. Air Drying (Optional)
0.6–0.8 MPa compressed air penetrates the filter cake, boosting evaporation efficiency by 40%.
Helps reduce cake moisture by another 5–10%, enabling dry stacking or direct disposal.
5. Plate Opening & Cake Discharge
Intelligent pull mechanisms open the plates sequentially, allowing cakes to fall off via gravity or scraper.
Discharge success rate >98% (vs. 85% in traditional units).
The automatic cloth cleaning system activates post-discharge, using high-pressure water or air jets. Filter cloth service life extends up to 1500 hours (vs. 600 hours).
