High Efficiency Industrial Rotary Disc Vacuum Filter for Iron & Non-Ferrous Ore Mineral Concentrate Dewatering Equipment

Description

The Yuwei disc vacuum filter is a high-efficiency continuous solid-liquid separation equipment powered by vacuum negative pressure. Optimized for high-density and fast-settling slurry conditions of iron concentrate, non-ferrous metal concentrates and other mineral materials, it is widely applied in non-metallic minerals, coal washing, chemical industry and environmental sludge dewatering scenarios, serving as the preferred core equipment for large-scale mineral dewatering processing.

Targeting the common drawbacks of traditional filters including low efficiency, high cake moisture and high operation & maintenance costs, this equipment features outstanding optimized advantages:

1. High Production Capacity for Large-Scale Production:

Adopting a modular multi-disc layout with 4-8 filter discs per unit, it achieves a unit area processing capacity of 1.2t/h·㎡ and a maximum daily output of 2000 tons. The processing efficiency is over 30% higher than traditional filters, fully meeting the continuous production demands of large-scale mineral processing plants.

2. Superior Dewatering Performance:

Equipped with a zoned continuous dewatering process, it stably reduces the moisture content of conventional mineral filter cakes to below 12%, and as low as 9.8% for coarse-grained iron concentrates. It effectively improves concentrate grade and cuts costs for transportation and smelting energy consumption.

3. Wide Working Condition Adaptability & Low Operation Cost:

Core components are made of wear-resistant and anti-corrosion materials for extended service life. The optimized sealing structure reduces vacuum leakage rate and energy consumption. It is compatible with various slurries with a pH value of 2-12, solid concentration of 20%-65% and particle size of 200-400 mesh, delivering excellent working condition compatibility.

4. High Automation Level:

It integrates a fully closed-loop automatic process including feeding, filtering, dewatering, cake discharging and cloth cleaning, supporting remote management and greatly reducing manual intervention and operational errors.

5. Compact Structure & Space-Saving:

The vertical modular layout reduces floor space by 40% compared with traditional filter presses under the same processing capacity, saving infrastructure and site costs.

Core Component Structure

Designed with modularization, high wear resistance and easy maintenance, all core components are specially optimized to adapt to the high-wear and continuous operation conditions of mines, ensuring high stability and long service life.

1. Filter Disc

Assembled with multiple high-strength engineering plastic fan-shaped filter segments, the filter disc features high structural strength, large porosity and excellent filtrate permeability, with a service life 1-1.5 times longer than traditional products. Equipped with high-smoothness polyester/nylon filter cloth, it delivers reliable particle interception, anti-clogging performance and high cake discharge rate. The filter cloth can be replaced according to material characteristics to adapt to diverse working conditions. The integral modular assembly enables convenient disassembly, replacement and maintenance.

2. Main Shaft & Air Distribution Device

• Main Shaft Assembly: Adopting a thick-walled seamless steel pipe main body, the shaft features high rigidity and anti-torsion deformation capacity with a design service life of over 10 years. Ceramic composite wear-resistant filtrate pipes are evenly arranged circumferentially, extending the service life 2-3 times compared with traditional steel pipes. The flange-free integral welding structure eliminates 90% of potential air leakage points and ensures excellent vacuum tightness. The high-precision wear-resistant cast iron friction disc at the end adapts to long-term rotary sealing operation.
• Air Distribution Head: Symmetrically arranged on the left and right sides with a high-precision end face sealing structure, the distributor features internally divided independent zones. It automatically switches vacuum, back-blow and cleaning circuits to avoid air and liquid cross leakage, ensuring accurate, continuous and stable filtration operation.

3. Guidance & Discharging Device

Equipped with a precise guidance structure, it controls the filter disc deflection within 2mm to ensure stable operation. Adopting the combined discharging mode of air back-blowing + flexible scraper assistance, it achieves thorough cake removal. Compared with pure mechanical scraping, this design greatly reduces filter cloth wear and prolongs accessory service life. The integrated automatic high-pressure cloth cleaning system realizes on-line filter cloth regeneration for long-term efficient operation.

4. Auxiliary Core Systems

• Tank Assembly: Welded with high-quality steel plates, the tank features high rigidity and tightness. Equipped with overflow, sewage discharge and cake discharge ports, it stably controls slurry liquid level and facilitates daily cleaning and maintenance.
• Frequency Conversion Stirring Device: Driven by an independent variable-speed system with two-speed automatic shifting, it adapts to fast-settling minerals. Uniform stirring eliminates slurry sedimentation and stratification to ensure regular filter cake formation. The shaft-end water seal structure prevents leakage and blockage for stable operation.
• Automatic Centralized Lubrication System: The programmable intelligent system provides timed and quantitative lubrication for all core transmission and friction points. It realizes automatic equipment maintenance, reduces mechanical wear and manual maintenance costs, and guarantees long-term stable operation.
• Electric Control System: Integrates main shaft speed regulation, stirring speed regulation and automatic lubrication control. Featuring high automation and simple operation, it adapts to intelligent continuous production of modern factories.
