Application
The DNT-type integrated belt sludge thickening and dewatering machine is designed for efficient treatment of surplus sludge and mixed sludge from biochemical processes in municipal wastewater treatment plants. It is also widely used for sludge dewatering across various industries, including manufacturing, leather, textile, chemical, and food processing.
Structure and Working Principle
The machine integrates a sludge thickener and dewatering unit, constructed with anti-clogging stainless steel flushing nozzles and specialized cleaning devices to ensure continuous and stable operation.
After chemical conditioning with a coagulant, the sludge is thoroughly blended in a mixer and directed to the gravity dewatering zone. Here, free water rapidly separates from the sludge through the filter belt gaps and is collected in the water collection tank.
The preliminarily thickened sludge then enters a wedge-shaped pre-pressure section, where it is evenly distributed and gently compressed to release further moisture. Subsequently, the sludge proceeds to the S-shaped multi-roller pressing section. Sandwiched between the upper and lower filter belts, it undergoes repeated shear forces and pressure from rollers of varying diameters, significantly enhancing dewatering efficiency and forming firm sludge cakes.
Finally, the dewatered cake is removed by a scraper and conveyed for disposal. The filter belts are automatically cleaned using high-pressure flushing nozzles to prevent clogging, ensuring consistent performance and longevity.
