The filter machine sector plate is a core component of filtration equipment (such as vacuum leaf filters and filter presses), used to support filter cloth, guide filtrate flow, and achieve solid-liquid separation. Its structure is a sector-shaped perforated plate, injection molded from high-density polyethylene (HDPE) or modified polypropylene (PP), with a smooth and corrosion-resistant surface. The plate surface is covered with trapezoidal or square filter holes (aperture 2–8mm), reinforced ribs are set at the edges to enhance rigidity, and a connection flange is installed at the top for easy installation. During operation, material permeates through the filter cloth to the plate holes, filtrate gathers radially to the central drainage pipe, and solid particles are retained on the filter cloth surface.
Product Applications
1. Chemical Industry: Titanium dioxide (TiO₂) filtration, sodium chloride crystallization separation, chemical waste residue treatment, suitable for strong acid/alkaline environments (pH 1–14).
2. Mining Sector: Tailings dewatering (e.g., iron concentrate), coal washing (coal slurry water treatment), wear resistance improved threefold compared to traditional metal plates.
3. Food Processing: Starch slurry solid-liquid separation, distiller's grains filtration, vegetable oil extraction, compliant with FDA food-grade material standards.
4. Environmental Engineering: Municipal sludge dewatering, electroplating wastewater treatment, paper white water recovery, anti-clogging design extends cleaning intervals by 30%.
Product Features
1. High-Efficiency Filtration: Trapezoidal hole structure reduces fluid resistance, filtrate penetration rate ≥25m³/(m²·h), 20% higher than traditional round hole plates.
2. Durable Design: Material is anti-aging (UV stabilizer added at 0.3%), service life >5 years (at room temperature).
3. Easy Cleaning and Maintenance: Low surface energy (water contact angle >105°), backwashing removes 95% of residues.
4. Lightweight Installation: Density only 0.95g/cm³ (1/8 of metal plates), operable by one person, reduces equipment load.
Product Functions
1. Filter Cloth Support: Provides a rigid base for the filter cloth to prevent collapse-induced filtration short circuits.
2. Fluid Guidance: Filter hole angles tilt 5° toward the center, accelerating filtrate collection and reducing filtration dead zones.
3. Uniform Feeding: Sector structure (central angle 120°) ensures even material distribution, avoiding local overload.
4. Online Monitoring: Reserved sensor interface (counterbore on flange side), can integrate differential pressure detection or temperature monitoring functions.
