grid for vacuum drum filter
The grid for vacuum drum filters, also known as a plastic mesh pad, is made of specialized plastic materials (e.g., polypropylene, polyethylene). Processed into a regular grid structure, its dimensions and performance parameters are tailored to the filtration process. As a key component of vacuum drum filter equipment, it functions to support the filter medium, channel the filtrate, and assist in filter cake discharge—ensuring efficient solid-liquid separation operations.
Plastic Mesh Pad Specifications
Our grid for vacuum drum filters is crafted from high – density polyethylene or polypropylene. With mesh sizes from 2 – 10 mm, thicknesses of 2 – 10 mm, and customizable dimensions, it suits diverse filtration needs.
| Parameter Category | Specific Parameters | Description/Remarks |
| Basic Material | Polypropylene (PP), Polyethylene (PE), PVDF, etc. | – PP: Good chemical resistance, cost – effective- PE: Excellent low – temperature resistance- PVDF: High – end, with strong corrosion and high – temperature resistance |
| Dimensional Specifications | Length: Customizable (e.g., 500mm – 2000mm typical) | Matches the circumference of the vacuum drum filter |
| Width: Customizable (e.g., 300mm – 1000mm typical) | Aligns with the width of the filter drum | |
| Thickness: 2mm – 10mm (common range) | Thicker for higher load – bearing; thinner for lower filtration resistance | |
| Structural Parameters | Mesh Shape: Square, Hexagonal, etc. | Square: Easy to manufacture; Hexagonal: Better force distribution |
| Mesh Size: 2mm – 10mm (side length for squares) | Smaller mesh for finer filtration; larger for higher flow rates | |
| Open Area Ratio: 30% – 70% | Higher ratio means better filtrate flow but lower structural strength | |
| Performance Parameters | Compressive Strength: 0.1MPa – 1MPa | Ensures no deformation under vacuum and filtrate load |
| Temperature Resistance Range | – PP: – 10°C to 100°C- PE: – 70°C to 90°C- PVDF: – 40°C to 150°C | |
| Chemical Resistance | Resistant to acids, alkalis, and organic solvents (varies by material) |
Structure Design
Our grid for vacuum drum filters is crafted from high – density polyethylene or polypropylene. With mesh sizes from 2 – 10 mm, thicknesses of 2 – 10 mm, and customizable dimensions, it suits diverse filtration needs.
Our designed Plastic Mesh Pad: tailored grid, secure edges, ideal thickness enhance filtration.
Mesh Structure: Features a regular grid pattern (such as the neat square layout shown in the image). The mesh size and spacing are engineered to match filtration processes, enabling smooth filtrate flow while effectively retaining filter residues. The edges typically have regular protrusions, locking grooves, or flat designs for precise fitting with drum equipment, ensuring secure attachment during drum rotation and other operational conditions.
Thickness and Strength: Boasts an optimal thickness that maintains structural stability and resists deformation under vacuum suction and filter cake accumulation pressure. This ensures the mesh pad’s integrity throughout the filtration process while keeping filtration channels unobstructed.
Easily install our plastic mesh pad: align edges with drum grooves, secure, fits tightly for stable vacuum filtration.
Plastic Mesh pad featuers
Plastic Mesh pad features: corrosion resistance, lightweight, smooth surface, precise grid, durable, easy cleaning, fits Rotary Vacuum Drum Filter well.
Corrosion Resistance
Exhibits excellent tolerance to various filtrates (acids, alkalis, solvents, etc.), resisting chemical erosion to extend service life, suitable for filtering media in diverse industries like chemical and pharmaceutical.
Lightweight
Lighter than metal mesh pads, reducing drum equipment’s operational load to facilitate energy efficiency and stable operation. Plastic materials are also easy to process and mold, enabling precise manufacturing of complex, regular grid structures.
Surface Smoothness
Minimizes filter residue adhesion on the pad surface, facilitating cake detachment and pad cleaning after filtration, improving filtration efficiency and reuse rate.
Plastic Mesh pad Application
Plastic Mesh Pad applies to Vacuum Drum Filters in chemical, pharmaceutical, food industries for efficient solid-liquid separation.
Filtration Support
Acts as a supporting structure for filter media (such as filter cloths, screens), providing stable support to the filter layer under vacuum suction. Prevents excessive deformation or damage of filter media due to pressure, ensuring filtration precision and efficiency.
Filtrate Diversion
Grid channels guide filtrate to flow quickly to the vacuum adsorption area, enabling gas-liquid separation and accelerating the filtration process. Meanwhile, rational grid design allows even distribution of filtrate, avoiding local slurry that affects filtration results.
Filter Residue Stripping Assistance
The mesh pad structure, in conjunction with drum operation and discharge mechanisms, facilitates smooth stripping of filter residues from the filter media. Ensures continuous filtration operations, reduces manual cleaning costs, and enhances production continuity.
