Release time:

2025-10-10

The spiral mesh belt is not only a filtration material—it’s also a carrier of green technology. It transforms manure management from an environmental burden into a valuable resource that fuels the circular agriculture model. As the nation’s “Dual Carbon” strategy and the green transformation of agriculture continue to advance, the combination of belt-type press filters and spiral mesh belts will increasingly demonstrate their significant value across sectors such as animal husbandry, biogas projects, and organic fertilizer production. Looking ahead, Xiamen Citius will remain committed to driving innovation, leveraging high-performance filtration materials and advanced equipment technologies to deliver even more reliable solutions for the sustainable development of global livestock farming.

In the wave of transformation sweeping through modern animal husbandry, “ Reduce pollution and carbon emissions, promote resource recycling ” It has become the dominant theme of development. As large-scale farming expands, the management of livestock and poultry manure is no longer just an environmental issue—it has evolved into a systematic project that affects farm productivity, ecological safety, and sustainable operations.
In this field, belt press filter machines ( Belt Press Filter has become the main equipment for sludge dewatering and solid-liquid separation, and one of its core components —— Helical Mesh Belt Spiral Filter Belt ） , is playing a crucial role.

I. The Realistic Challenges in Livestock Manure Management

Large-scale farming generates enormous amounts of manure; for instance, a single pig produces about 1.5 Tons. If discharged without proper treatment, it can lead to issues such as eutrophication of water bodies, soil acidification, and greenhouse gas emissions. Meanwhile, the key step in resource recovery from manure lies in “ Solid-liquid separation ”。

Traditional centrifugal dewatering or thickening methods often consume high energy, incur significant maintenance costs, and result in sludge with relatively high moisture content. In contrast, belt press filters… Continuous operation, low energy consumption, and stable dewatering performance Its features make it the preferred solution for medium- to large-scale farms.

In these types of equipment, the filter belt performance directly determines the separation efficiency, operational stability, and the subsequent composting utilization results.

II. Structure and Characteristics of the Spiral Mesh Belt

Helical Mesh Belt Spiral Filter Belt ) is a filter mesh belt made from polyester monofilament or multifilament yarns, joined together through a spiral interlocking process. Unlike traditional woven filter cloths, it employs Weftless yarn-splicing structure , relying on the interlocking of spiral links to form a stable whole, resulting in a smooth mesh surface with high strength and excellent permeability.

Its main features include:

  1. High strength, highly tensile-resistant
    Made from imported polyester monofilaments, it boasts high tensile strength and resistance to deformation, making it ideal for high-tension operation under continuous pressing conditions.
  2. Good water permeability and desliming performance
    The spiral-structured pores are uniformly distributed, ensuring smooth drainage and enabling efficient dewatering even at low pressure, thereby reducing the moisture content of the sludge cake.
  3. Not easily clogged, easy to clean
    The surface is smooth and even, making it difficult for residues to embed themselves into the fibers, and it can be combined with an online rinsing system to achieve self-cleaning.
  4. Seamlessly joined for strong durability and long service life
    Employing seamless splicing or steel-buckle connection methods, it offers excellent wear resistance and fatigue strength, significantly extending its lifespan compared to ordinary filter cloths. 30% That's all.
  5. Wide temperature range and excellent chemical resistance
    Capable of withstanding the corrosive environment posed by varying compositions of livestock and poultry manure, making it suitable for different types of farms, such as pig farms, cattle farms, and chicken farms.

III. Application Value in Belt Press Filters

In a belt press filter, the spiral mesh belt plays a crucial role throughout the entire separation process:

  1. Gravity Dewatering Zone
    The mesh belt features a smooth surface and high permeability, enabling rapid drainage of free water from the manure liquid and creating favorable conditions for subsequent pressing.
  2. Wedge-shaped Pre-compression Zone
    The helical structure imparts excellent flexibility to the mesh belt, enabling it to closely conform to the roller while achieving gradual pressing without compromising the filter cake's structure.
  3. High-pressure Dewatering Zone
    Due to the high tensile strength of the mesh belt, it can withstand repeated compression from multi-stage rollers without deformation, ensuring that the moisture content of the discharged mud can be as low as 70%-75% , significantly better than traditional filter cloths.
  4. Unloading and Cleaning Area
    The filter cake has excellent peelability, enabling automatic discharge while preventing residue from sticking easily. Combined with a high-pressure spray system, the mesh belt can operate continuously. 24 More than an hour without clogging.

IV. Spiral Mesh Belts Drive Green and Circular Practices in Animal Husbandry

At “ Turning waste into treasure ” In modern farming systems, the application of spiral mesh belts not only enhances processing efficiency but also promotes the re-resourcefulness of manure and waste.

  • Fecal residue portion After being pressed and dehydrated, the moisture content is reduced, allowing it to be directly composted or processed into organic fertilizer for agricultural reuse.
  • Filtrate portion After further sedimentation or biochemical treatment, it can be reused for agricultural irrigation or as recycled wash water.

With an average daily sewage volume 100 Taking a medium-sized pig farm of tons as an example, equipped with a belt-type press machine. + After the spiral mesh belt system, approximately per ton of manure can be reduced 50 The annual savings in treatment energy consumption from the evaporation load of kilograms of water can exceed 30% , operational and maintenance costs reduced by approximately 25%。

More importantly, this system has achieved the transition from “ Pollution source ” To “ Resource Source ” The transformation helps the farm move toward Clean production, ecological farming The new era.
