1、 Main functional features:

1The main dehydration section adopts a very advanced and reliable vertical system“S”The design of the roller filter press drainage structure greatly exceeds the dehydration effect and processing capacity of traditional machines, and the moisture content of the filter cake is lower than that of ordinary machines10-15%More processing capacity than ordinary machines30-60%.
2Low energy consumption and low-cost operation.
3Advanced structural design and wide applicability.
4The technology of the mesh belt speed regulation and correction control system is advanced, which can ensure long-term stable operation.
5The selection of the dewatering belt for this machine is based on experiments and practical experience. Its permeability, wear resistance, viscosity, and cake stripping properties are better selected according to the actual materials, ensuring good dewatering effect and lower solid content of the belt washing water.
6The transmission and electrical control system of this machine adopts well-known domestic brand products and components, which are very stable, reliable, durable, and have an extremely low failure rate.
7The host gravity free dehydration adopts a unique multi roll large arc surface arrangement dehydration device, greatly enhancing the pre dehydration effect of low concentration slag. The strong clamping and squeezing structure design of the main dehydration area is advanced, ensuring that the slag liquid separation runs in the opposite direction in the later stage without forming reverse osmosis.
8Select high-quality anti-corrosion materials and manufacture spare parts.
9The parts of this machine that come into contact with sludge or water are all made of304#High quality stainless steel material, the remaining carbon steel parts are anti-corrosion treated with hot-dip galvanizing (can be reheated and sprayed with plastic) or surface sandblasting and rust removal, followed by four layers of thickened fluorocarbon paint for high-strength anti-corrosion treatment. Its acid and alkali corrosion resistance and rust prevention ability can reach more than ten years.
10Fully automatic operation, easy to operate and maintain.

3、 Working principle and workflow:

1working principle

The dewatering process of belt filter press can be divided into four important stages: pretreatment, gravity dewatering, wedge-shaped zone preloading dewatering, and press dewatering.

1.1Preprocessing stage:

The flocculated material is gradually added to the filter belt, causing the free water outside the flocs to separate from the flocs under the action of gravity, gradually reducing the moisture content of the sludge flocs and decreasing their fluidity. Therefore, the dewatering efficiency of the gravity dewatering section depends on the properties of the filter medium (filter belt), the properties of the sludge, and the degree of flocculation of the sludge. The gravity dewatering section removes a significant amount of water from the sludge.

1.2Wedge preloading dehydration stage:

After gravity dewatering of sludge, the flowability significantly decreases, but it is still difficult to meet the requirements of the pressing dewatering section for sludge flowability. Therefore, a wedge-shaped pre pressing dewatering section is added between the pressing dewatering section and the gravity dewatering section of sludge. The sludge undergoes slight pressing dewatering in this section to remove free water on its surface, and its flowability is almost completely lost. This ensures that the sludge will not be squeezed out in the pressing dewatering section under normal circumstances, creating conditions for smooth pressing dewatering.
