D-NTY series belt thickening and dewatering machine makes reference to the filter press machine’s structure produced by Germany LOGIC, and Japan Mitsubishi. To meet the technical demands of State Environmental Protection Administration, filter press machine which have three-dimensional rolls is designed through studying, absorbing, and promoting. (It initiated in the whole nation) this design make the machine more scientific and fashionable. The phenomenon that half of the rolls loose their function in the horizontal designed machine can not happen here. Based on other machines, many parts of this new machine are improved. Thickening and dewatering areas are increased. These entire characters make the new machine has the best performance index. This machine has good handling capacity and adaptive capacity for different sludge. The filter mess has high solid rate. It can work for 24-hours. In conclusion, our belt thickening and dewatering machine is the best.
It is proper for treatment of city live waste water, medicine, galvanization，paper making, leather, printing and dyeing textile, metallurgy, chemistry, slaughtering, food processing, brewing, and environment protection projects. It’s the most ideal equipment for environment protection and resource recycling.
Main designing features:
Proper structure design:
The structure is stable and easy to repair. It’s very neat, and the most common operating parts are in good poison. This kind of structure is really neat and beautiful.
Outstanding corrosion resistance:
All the parts that can touch water are stainless steels. The structure is stainless steel or hot galvanized. (Not hot painting) (Thickness of zinc inside and outside no less than 80μm) It is ensured that there’s no rust in 5 years.
Special design:
Tapering roll dewatering technology is used in the filter dewatering area. Sludge loosing from the sides can be avoided, so sludge handling capacity is improved.
Advanced filter screen washing technology:
Filter screen sludge remover is designed for the belt washing system. It can save much water. Self-washing sewage filter is also designed to take the water in Secondary sedimentation tank as the washing water. In this way water cost is reduced, and environment is protected.
Reliable running performance:
Air control valve links the air cylinder, this kind of correction system design makes it efficient. Both sides of the filter belt can be corrected at one time. Complete protection equipment if designed to ensure reliability. Unexpected damage can be avoided.
PCL control design:
PCL control can be designed according to high grade customers. Principle: to adjust sludge quantity, flocculants quantity automatically according to the working speed. In this way high production rate and dewatering rate can be achieved, and no operators are needed.
Developed application technology:
To achieve the best dewatering purpose, different filter belt, flocculants, and secondary equipments should be used for different kinds of sludge.
It is proper for sludge dewatering of city live waste water, printing and dyeing textile, paper making, food processing, medicine, chemistry, metallurgy, and oil.
