Application of industrial filter cloth in belt press filter presses for pulp filtration in paper mills
In the papermaking industry, the dewatering process of pulp has a significant impact on the quality and production efficiency of the final paper. With increasing environmental protection and energy-saving requirements, Belt press filter press Due to its high efficiency, continuous operation, and energy-saving features, it is widely used in paper mills. And Industrial filter cloth As a key component of the equipment, its performance directly affects the operation of the entire pulp filtration system.
I. Basic Principles of Belt Press Filter Presses
A belt press filter press is a continuously operating solid-liquid separation device, mainly composed of two circulating filter belts, a pressing roller group, a tensioning device, a drive system, etc. After the pulp is evenly spread on the filter cloth by the cloth feeding device, it successively passes through the gravity dewatering zone, the wedge zone, and the high-pressure roller zone, achieving the gradual removal of free water to bound water, and finally forming a filter cake that is discharged.
This equipment operates stably, has a large processing capacity, and a high degree of automation, making it particularly suitable for pre-concentration or dewatering of pulp in large and medium-sized paper mills.
II. The Role of Industrial Filter Cloth in Pulp Filtration
In the belt press filtration process, the filter cloth is not only a conveying medium but also plays a multiple role in filtration, support, and dewatering. This is specifically reflected in the following aspects:
- Filtration performance High-quality filter cloth can effectively intercept fine fiber particles in the pulp, ensuring the passage of clear water while maintaining good air and water permeability.
- Mechanical properties The filter cloth must have good tensile strength and wear resistance to withstand continuous tension and roller pressure.
- Stability and adaptability The filter cloth should maintain dimensional stability during long-term operation, without deviation or wrinkling, and adapt to various machine structures.
III. Key Points for Filter Cloth Selection
For the pulp characteristics of paper mills (such as waste pulp, chemical pulp, mechanical pulp, etc.), filter cloth selection should focus on the following indicators:
- Pore size and permeability Select the appropriate filter cloth structure (such as single-layer, double-layer weaving) according to the pulp particle size and moisture content to ensure that it can effectively retain fibers while achieving rapid dewatering.
- Surface smoothness Ensure uniform pulp distribution during filter cloth operation, which is conducive to forming a filter cake with uniform thickness.
- Peelability The filter cake should detach from the filter cloth smoothly, reducing sticking and improving production line efficiency.
IV. Xiamen Citius (Xiamen Citius) Advantages of industrial filter cloth applications in the papermaking industry
