Automatic High Overhead Beam Filter Press for Sludge Dewatering | Mining Tailings Filter Press

Product Overview

The High Overhead Beam Filter Press is an upgraded heavy-duty solid-liquid separation equipment developed on the basis of traditional chamber and membrane filter presses. Characterized by an elevated main beam, top-suspended filter plates, and no through bottom beam, it is a fully automatic high-pressure dewatering unit ideal for industrial slurries with high solid content, high viscosity, and difficult dewatering properties.

Core Design Philosophy

1. Eliminates cake sticking & residue issues:

   Traditional bottom-beam models have dense bottom cross beams, where highly viscous mud cakes easily adhere and accumulate, requiring manual cleaning. The overhead design removes bottom obstructions, enabling pure gravity discharge.

2. Prevents uneven stress & plate warping/leakage:

   Conventional units use bottom roller supports for filter plates, leading to uneven stress, bottom deformation, and seal leakage under long-term high pressure. The top suspension design ensures uniform vertical stress on filter plates.

3. Reduces frame corrosion & extends service life:

   The main beam of ordinary models sits close to the ground, prone to rust from prolonged exposure to sewage, mud, and corrosive waste liquids. The elevated frame keeps components away from contaminated liquid levels.

4. Improves maintenance access & automation integration:

   Traditional equipment has a compact bottom structure, making cloth replacement and maintenance difficult, and incompatible with belt/spiral conveyors. The fully open bottom supports automated assembly line layouts.

Centered on suspended load-bearing + fully open bottom, it optimizes mechanical structure at the cost of increased height, delivering superior material adaptability, lower failure rates, and minimal manual intervention.

Main Structure & Key Technical Features

Main Modular Components

The press consists of six highly modular assemblies for easy disassembly, installation, and maintenance:

1. High Overhead Beam Frame Assembly: Dual elevated main beams, fixed end plate, and movable tail plate— the sole main load-bearing structure.
2. Filtering & Compression Unit: Top-suspended filter plates, filter cloths, lifting lugs, and sealed compression surfaces.
3. Hydraulic Compression System: Rear-mounted cylinder, hydraulic power unit, and pressure-holding valve group, providing high-pressure sealing force.
4. Elevated Plate Pulling System: Main beam rails, variable-frequency plate pulling trolley, and chain drive mechanism.
5. Intelligent Control System: PLC touchscreen, pressure sensors, limit switches, and automatic interlock protection.
6. Auxiliary Functional Unit: Filter cloth washing, membrane squeezing, air drying, flip plate liquid collection, and discharge conveyor interfaces.

Key Technical Advantages

1. Elevated Suspended Main Beam: Thickened box beam with increased ground clearance and no through bottom cross beams. High structural rigidity and deformation resistance ensure stable plate pulling without vibration.
2. Top-Suspended Filter Plate Stress Structure: Filter plates hang from main beam rails via high-strength lifting lugs (no bottom rollers). Consistent vertical suspension and aligned stress axes prevent distortion under high pressure.
3. Fully Open Bottom Space: No columns or cross beams beneath the unit, providing unobstructed vertical discharge space.
4. Elevated Rail Plate Pulling Mechanism: Plate pulling trolley mounted above the main beam, isolated from ground mud and water. Clean rails resist fouling/sedimentation, enabling smooth, stable, low-noise plate pulling.
5. Integrated Hydraulic Pressure-Holding System: Large-diameter rear cylinder delivers powerful, stable compression force, maintaining long-term high-pressure sealing and eliminating high-pressure feed slurry leakage.

Application Scenarios & Working Conditions

Ideal Working Conditions

Designed for heavy-duty, difficult dewatering applications, it is best suited for:

• Material Properties: High viscosity, fine particles, high mud content, adhesive slurries that conventional presses struggle to dewater.
• Environmental Conditions: Highly corrosive sewage, muddy floors, dusty/humid workshops.
• Production Requirements: Continuous mass production, high automation, and minimal manual cleaning.
• Dewatering Targets: Low filter cake moisture content, dry stacking/storage, and reduced transportation volume.

Key Application Industries

• Sand & Stone Mining: Washing tailings, stone powder mud, iron ore tailings dewatering.
• Wastewater Treatment: Municipal sludge, industrial wastewater, biochemical sludge solidification.
• Building Materials & Stone: Marble/granite cutting mud, ceramic slurry.
• Fine Chemicals: Dyes, resins, electroplating/pickling sludge, viscous chemical slurries.
• Metallurgy & Coal Chemicals: Coal slime, metallurgical slag slurry, heavy metal solid waste dry discharge.
