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.

Main Features
1. The motor drive can be adjusted steplessly, and the operating
speed can be adjusted at any time, with strong adaptability.
2. Special flushing nozzle and anti-clogging device make the filter
belt clean.
3. The dewatering head roller adopts T-shaped drain groove, and the
squeezed water flows out quickly.
4. The gravity dewatering section is inclined, and the static head
of the sludge is enlarged, which can enhance the dewatering effect
and make the sludge fully thickened before pressing.
5. The whole machine has a compact structure, automatic correction
of the filter belt, low operating noise, low power consumption, low
dosage, good dehydration effect, and low operating cost.
