The rotary drum thickening belt filter press sludge dewatering machine has two functions, concentration is processed in the rotary drum and dewatering is completed in the belt filter press part. It is often used in urban sewage treatment.
ZDY Rotary drum belt filter press, it is mainly used for processing the sludge which is not concentrated in the thickening pool (such as A/O residual sludge), the sludge can be pre-dewatered by the rotary drum concentration, thus, this machine has two functions: concentraion and dewatering, its capacity is higher than the other dewatering devices which with simple filter pressing.
Structure & Working Principle
The main machine is composed of conditioning tank, concentrating shrink drum and belt filter, when the flocculated sludge feeds into the rotating thickening drum, the moving water flows from the rotary drum gap, washing device is set on the top of the rotary drum, which is to wash the drum. After thickening and dewatering, the sludge is distributed and feed onto the filter belt thoroughly. After pressed by the gravity dewatering zone, wedge compression zone, pre-pressing dewatering zone, low pressure dewatering zone, middle pressure dewatering zone, high pressure shear dewatering zone etc, the presser is put onto the sludge along the belt forwarding direction consistently, and the sludge cake will be output at the outlet port.

1. Adopting advanced technical design ideas, combined with years of design experience and integrated design, Belt Filter Press can run stably, no shock, no vibration and no noise.
2. The surface has been treated as anticorrosion and painted with beautiful appearance. The structure is strong and durable.
3. Belt position correcting system: automatic continuous detection, extend belt’s life.
4. Press roller: SUS304, reinforced welding, machined by fine processing, enough strength.
5. Air pressure control device: the filter cloth tensioned by cylinder runs in its scope stably without leakage, high security.
6. Belt cloth: GKD, good durability and excellent corrosion resistance.
7. Control panel: Omron or Schneider. PLC adopts Siemens, easy operation and maintenance.
9. Flocculator tank: Adopts different layout with different sludge inlet concentration, to mix the polymer and sludge thoroughly.
