Automatic Quick-Opening Filter Press
An automatic quick-opening filter press is a highly efficient and intelligent solid-liquid separation device, widely used in mining, chemical, metallurgical, papermaking, and environmental protection industries. Compared with traditional filter presses, this type of equipment has significant advantages in filtration efficiency, degree of automation, and maintenance costs.
What is an Automatic Quick-Opening Filter Press?
An automatic quick-opening filter press, as the name suggests, has two core features: “automation” and “rapid plate opening.” Its design aims to shorten the non-working time of each filtration cycle (such as plate opening, unloading, and plate closing), significantly improving the equipment’s processing capacity.
Core Structure and Working Principle
Filter plate system
Typically employs a combined linkage structure or plate chain linkage structure, allowing the filter plates to be quickly opened and closed by the plate shifter, completing the unloading action of multiple filter chambers in one operation.
Hydraulic system
Controls the clamping and loosening of the filter plates, using high pressure to compact the filter cake and improve the dewatering effect.
Control system
Equipped with a PLC automatic control cabinet, it offers one-touch start, automatic cycle, and fault alarm functions.
Discharging system
The filter plates are quickly pulled apart one by one, and the filter cake automatically falls off due to its own weight or vibration, significantly reducing manual intervention.
Advantages of Quick-Opening Filter Presses
- High-Efficiency Production: Fast unloading speed, saving an average of 3-5 minutes per cycle, suitable for large-scale continuous operation.
- Fully Automated Operation: From pressing, feeding, pressure holding, unloading to cleaning, the entire process can be automated.
- Reduced Labor Costs: Operators only need to perform routine inspections, significantly reducing manual labor intensity.
- Low filter cake moisture content: Optimized feed pressure and filtration time improve solid-liquid separation efficiency.
- High operational stability: Modular design facilitates maintenance and reduces failure rate.
Application Scenarios
- Mineral processing plants: Used for tailings dry discharge and concentrate dewatering.
- Coal chemical industry: Used for coal slime dewatering via pressure filtration, reducing the burden on subsequent drying processes.
- Municipal wastewater treatment: Achieves high-dryness dewatering of sludge, facilitating transportation and treatment.
- Chemical industry: Used in solid-liquid separation processes such as treating reaction precipitates and catalyst recovery.
Maintenance and Upkeep
Daily maintenance
- Check the hydraulic oil level and pressure
- Clean the filter cloth and filter plates
- Inspect seals
- Lubricate transmission components
Regular maintenance
- Change hydraulic oil (every six months)
- Inspect the electrical system
- Replace worn filter cloth (every 3-6 months)
- Inspect quick-opening mechanism (monthly)
Common Faults
- Lack of pressure: Check the hydraulic system and seals.
- Leakage: Replace the filter cloth and adjust the pressure.
- Slow opening and closing: Check the hydraulic pump and clean the guide rails.
- Filter cake does not fall off: Adjust the air-drying time and clean the filter plates.
