Products Description
The main unit is constructed from integrally welded national standard square tubes. The surface is high-pressure sandblasted to remove rust and scale, then coated with four layers of fluorocarbon paint, providing over ten years of resistance to acid and alkali corrosion.
Key components are made of high-performance stainless steel, including the main dewatering roller, fender, water collection trough, waterproof cover, and nozzle.
The bearing seat is made of high-quality cast iron with a fully sealed structure. The bearings are high-quality double-row roller bearings with a three-year warranty.
The squeeze rollers, drive rollers, and guide rollers are made of high-quality seamless steel pipes, covered with wear-resistant rubber, and come with a three-year warranty.
High-quality filter screens are used, offering high strength, excellent water permeability, resistance to clogging, ease of cleaning, and ease of assembly and disassembly. Different filter screens are selected based on the physical properties of the sludge.
The belt press for sludge dewatering is used for treating sludge that has not been concentrated in a concentration tank (such as residual sludge from the AO method and SBR method), and it also has dual functions of concentration and dewatering.
The belt press for sludge dewatering is effective in phosphorus removal. After chemical conditioning and modification, the material gradually aggregates into flocs. After initial precipitation, it enters the concentration and dewatering section. The water in the sludge flocs is separated from the flocs under the action of gravity. The wedge-shaped pre-pressing dewatering section slightly squeezes the material to shape it, ensuring that the sludge is not squeezed out in the pressing dewatering section. After entering the first press dewatering roller, the sludge is carried by two tensioned filter belts on the top and bottom. These belts repeatedly squeeze and shear the material around different press rollers, removing a large amount of capillary water and producing a sludge cake with high solid content, thereby achieving material dewatering.

Feature
Design: Integrated design for both concentration and dewatering functions, ensuring smooth operation without impact, vibration, or abnormal noise.
Structure: The appearance is coated with a topcoat, making it beautiful and elegant, as well as chemical-resistant. The structure is sturdy, exquisite, and durable.
Main Body: Fully automatic control with a high degree of automation, capable of both remote and on-site control, effectively reducing labor and operational intensity. The model has a compact structure, a beautiful appearance, and a small footprint, which helps save on construction costs. It also features low energy consumption and low noise, avoiding the disadvantages of high power consumption and high maintenance costs seen in centrifugal dewatering machines.
Technology: Effectively prevents filter cloth deviation, improving its service life and reducing maintenance costs. The sludge dewatering wedge zone adopts a 6-8 degree angle, and the length of the wedge zone is extended, which effectively controls the uniformity of the sludge cake before it enters the pressing zone. The free water on the surface of the sludge is further removed, and the sludge cake becomes uniform, achieving better results in the pressing zone.
Application
Small and Medium-Sized Urban Domestic Sewage Treatment Plants: Belt sludge dewatering machines are widely used in small and medium-sized urban domestic sewage treatment plants, effectively treating fine-grained inorganic sludge.
Water Treatment Plants: The belt-type concentration and dewatering integrated machine is suitable for use in water treatment plants, specifically for sludge dewatering in industrial wastewater treatment.
Urban Sewage Treatment Plants: This equipment is also commonly used in urban sewage treatment plants to process sludge generated from various industrial wastewater treatments.
Textile, Livestock, and Landfill Sites: Belt-type concentration and dewatering integrated machines are also utilized in industrial wastewater treatment at textile mills, livestock facilities, and landfill sites.
Pharmaceutical, Papermaking, Leather Industry, Brewing, Food Industry, Metallurgy, Chemical Industry: These industries also widely use belt-type concentration and dewatering integrated machines for sludge treatment.
