Application
The DT belt dewatering machine is mainly used for the dewatering of
residual sludge or mixed sludge in the biochemical treatment of
municipal sewage to reduce its volume to facilitate further
landfill, incineration and other treatments. It can be applied to
water supply, drainage, papermaking, etc. Dewatering of sludge in
various industries such as foundry, leather, textile, chemical,
food, etc.
Structure and Working Principle
The equipment tensions the upper and lower filter belts through a
series of rollers and drums. The sludge sandwiched between the
filter belt shear force continuously squeezes the free water in the
sludge to complete the mud-water separation process. . The
dehydration process is generally divided into three stages: gravity
dehydration section, wedge pre-press section, medium and high shear
dehydration section.
Main Features
1. The stepless adjustment of the motor drive can adjust the
running speed at any time, and the adaptability is strong.
2. The special flushing nozzle and anti-clogging device make the
filter belt flush 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.
Packing and Delivery
1. Waterproof packing with the international export standard by
20ft, 40ft, 40hp container. Equipment Fittings, Electric Motor and
Power Cabinet will be packed in Wooden Case or Iron Box. Other
Equipment will be packed by Color-Stripes Plastic Cloth.
2. The whole plant machinery size are large as normal, so we will
use Waterproof cloth to pack all of them. The motor, gear box or
other easily damaged parts, we will put them into box. We have a
professional shipping department, they will try their best to save
your container quantity.
