Application of industrial filter cloth and filter belts in pulp pressing in paper mills

—— A key role in the plate and frame filter press process

In modern papermaking, pulp dewatering is crucial for improving production efficiency and paper quality. Plate and frame filter presses are widely used in pulp pressing processes due to their stable dewatering effect and high solid content in the filter cake. Industrial filter cloths and filter belts, as the core media of the equipment operation, directly determine the filtration effect and the stability of the system operation.

Process characteristics of paper pulp dewatering

Pulp is a suspension of plant fibers produced by chemical or mechanical methods. The fibers are long, have high water content, and are loosely structured. Traditional mechanical dewatering is difficult to meet the dual requirements of efficient filtration and high-dryness filter cakes, so most paper mills use plate and frame filter presses for deep dewatering, significantly reducing subsequent drying energy consumption.

Working principle of plate and frame filter press

A plate and frame filter press consists of alternately arranged filter plates and frames to form filter chambers. Under pressure, the pulp enters the filter chambers, the liquid portion passes through the filter cloth and is discharged, and the solids accumulate on the surface of the filter cloth to form a filter cake. As the filtration cycle progresses, the filter cake thickness gradually increases, ultimately achieving pulp concentration and solid-liquid separation.

Application points of industrial filter cloth and belts

  1. Filtration precision and permeability
    Filter cloths used for pulp pressing in papermaking need to have good permeability to ensure rapid drainage, and also have an appropriate pore size to prevent fine fibers from being lost with the filtrate, ensuring the recovery rate.
  2. Compressive strength and wear resistance
    During the plate and frame filtration process, the filter cloth must withstand high-pressure squeezing and repeated tensioning, so it requires excellent tensile strength and wear resistance to extend its service life and reduce replacement frequency.
  3. Easy stripping and cleanability
    High-quality industrial filter cloth has good filter cake stripping properties for easy cake unloading, and supports various cleaning methods such as backwashing and spraying to improve maintenance efficiency.
  4. Adaptable structural design
    According to the pulp concentration and process requirements of different paper mills, Xiamen Citius (Xiamen Citius) can provide single-layer, double-layer, and composite woven structures, adapting to different specifications of filter presses.

Application advantages

  • Improved dewatering efficiency : High-quality filter cloth improves filtration speed and dryness, shortening the filtration cycle;
  • Stable system operation : Stable belt operation, controllable tension, reducing downtime;
  • Reduced operating costs : Durable materials extend the filter cloth replacement cycle, saving labor and maintenance costs;
  • Ensuring paper quality : Effectively controlling the leaching of impurities, improving pulp purity and paper consistency.
