DNY
Product Introduction
The DNY-type gravity belt filter press is designed for treating sludge that has not undergone thickening in a settling tank, such as A/O or SBR excess sludge. This equipment integrates both sludge thickening and dewatering into one process. Unlike the rotary drum thickening belt filter press, it relies on gravity drainage through the filter belt for moisture removal, making it suitable for applications that require higher treatment capacities.
Overall structure
The processes of sludge feeding, chemical dosing, mixing, and reaction are all completed within the dewatering unit itself. The subsequent stages—dewatering and discharge of the sludge cake—are carried out under laminar flow to ensure steady operation of the pipeline.
To guarantee reliable long-term performance, the dewatering equipment must be engineered and manufactured to withstand demanding working conditions, including elevated temperatures and environments with 100% humidity.
Once each component has passed inspection, the unit can be assembled. During operation, the dewatering machine should function smoothly without shocks, excessive vibration, or unusual noise.
Technical Parameter
| Material: SUS304/316 | Motor insulation level: F |
| Filter belt width (mm): 1000 | Power: 380V，50HZ，3 phrase |
| Capacity (m3/hr): 12.5~15 | Flushing pressure (MPa): 0.5Mpa |
| D.S. Dried Sludge （kg/h): 100~188 | Flushing quality (m3/hr): 6~8 |
| Press section filter belt speed (m/min): 1.0~5.0 | Weight (kg): 2000 |
| Thicken section filter belt spe (m/min): 3.5~17.5 | Feed moisture content (%): 98~99.5 |
| Motor main power (Kw): 1.49 | Sludge cake moisture content (%): 75~85 |
| Motor protection grade: IP55 | Speed control mode of driving mode:Frequency control |
Scope of application
The gravity belt filter press is a continuously operating system designed for efficient solid–liquid separation. It can be applied across a wide range of industries, including municipal wastewater, chemicals, metallurgy, mining, food processing, and papermaking. In municipal sewage treatment facilities in particular, it offers a straightforward process flow, strong adaptability to varying sludge conditions, stable continuous operation, and high overall handling efficiency.
Features
The system supports continuous operation with a high processing capacity, while maintaining low energy consumption and minimal noise, creating a cleaner and more comfortable working environment.
The main drive adopts a variable-frequency control system, allowing flexible speed adjustment to match different operating conditions.
With an optimized air circuit layout and premium pneumatic components, the equipment operates with greater stability, offers longer service life, and helps reduce routine maintenance expenditure.
The gravity drainage zone is equipped with adjustable sludge plow devices, providing extended drainage time. This setup breaks the sludge’s surface tension and significantly enhances gravity dewatering performance.
To ensure users achieve reliable process results, we can offer sludge testing, model selection guidance, system commissioning, and other supporting services based on customer requirements.
