Structure and Working Principle
The equipment is mainly composed of belt thickener and dewatering
machine. After adding coagulant, the sludge will flow into the
gravity dewatering section after being fully mixed in the sludge
mixer. Under the action of gravity, the sewage will flow into the
gravity dewatering section. A large amount of free water in the mud
flows out from the gap of the filter belt, enters the water
collection tank, and then is guided by the wedge-shaped
pre-compression section, so that the sludge is gradually leveled
and slightly squeezed for further dehydration, and then enters the
S-shaped multi-roller In the pressing section, the sludge is
sandwiched between the upper and lower filter cloths and repeatedly
squeezed by several spokes of different diameters. At this time,
the sludge is sheared and the sludge is further dewatered to form a
mud cake. Finally, the sludge is removed by a scraper. The cake is
scraped off and transported out, and the upper and lower filter
belts are washed and then reused.
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.
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.
