Polyester Mesh Belt for Belt Press Filter

Professional Mesh Belt Manufacturer for Belt Press Filter

Belt Press Filter


Belt filter press is widely used in industries such as environmental protection, municipal, mining, power, chemical, electronics, food, pharmaceuticals, textiles, etc. It is a solid-liquid separation equipment mainly used for sludge treatment and dewatering processes. It can separate sludge into sludge cake and clean water. The sludge cake can be directly transported, buried or used for other industrial purposes, while the clean water can be recycled.

Polyester Spiral Mesh Belt
Polyester Spiral Mesh Belt is a continuous mesh fabric woven around high-strength polyester monofilaments in a spiral pattern, seamlessly joined by a connecting ring and joint system. This design originated from the papermaking dewatering process and gradually developed into a key medium for solid-liquid separation and sludge dewatering.

-- High Strength and Stability The spiral mesh belt is made of high toughness polyester monofilament material. After precision heat setting treatment, it has extremely strong tensile and dimensional stability, and can withstand long-term compression tension and mechanical stress without deformation. --Good Permeability and Mud Discharge Performance Polyester spiral mesh belt has a continuous spiral opening structure with uniform pore size and low fluid resistance, which enables the water in the mud to be quickly discharged and forms a thick filter cake, helping to improve the dehydration rate and solid content of the mud cake. --Wear Resistant and Anti Clogging Design At the sand washing site, the filter cloth often comes into contact with high hardness particles (such as quartz sand and fine sand), which are prone to wear and tear. The smooth surface and monofilament structure of the polyester spiral mesh belt effectively reduce the risk of wear and blockage, while also being compatible with high-pressure cleaning systems to maintain the cleanliness of the mesh surface. -- Excellent Chemical and Thermal Stability Faced with flocculants, acidic and alkaline environments, or temperature fluctuations in the sand washing system, polyester spiral mesh can maintain good physical properties and filtration stability, extending its service life. -- Flexible Splicing and Convenient Maintenance Polyester spiral mesh belt can be connected with metal buckles or polyester joints, which facilitates on-site replacement and maintenance, shortens downtime, and improves the overall operational efficiency of the production line.

Double Woven Type Polyester Mesh Belt
The woven type polyester mesh belt is mainly have twill pattern and satin pattern for belt press filter machine.

Double Layer Woven Structure The outer layer is made of thicker supporting fibers, which provide tensile strength and dimensional stability; The inner layer is woven with fine fibers to optimize the water filtration channel, allowing the filtrate to pass quickly and fine particles to be more fully retained. High breathability and uniform water filtration performance.
By scientifically controlling the latitude and longitude density, the surface of the filter cloth is made smooth, ensuring even distribution of sludge and avoiding short circuits in water flow. Excellent Cake Stripping Properties The surface of the filter cloth undergoes special heat setting and surface modification treatment, allowing the mud cake to naturally peel off after pressing, reducing the number of manual cleaning times and extending the continuous operation time of the equipment. Tensile Resistance and Dimensional Stability In a belt press, the filter cloth is subjected to high tension and high friction for a long time. The tensile strength of high-quality filter cloth can reach ≥ 2000 N/5cm, the elongation at break is ≤ 10%, and it can maintain good tension under high load conditions. Acid Alkali and High Temperature Resistance Performance Sludge often contains acidic and alkaline chemicals, and filter cloth needs to withstand corrosive environments with pH 3-11. The temperature of some process sections can reach 80 ℃, so the filter cloth needs to have good thermal stability.
