FTB Series Rotary Drum Sludge Dewatering Machinge (for High Concentration)

  • SFC


Working principle

1: Machine was composed of rotary drum and belt press dewatering.The processing flow is : sludge inlet, polymerdosing, mixing,reaction,thickening and dewatering under steady flow conditions to remove the water from sludge.

2: The sludge and flocculants are added to the conditioning tank together and after proper stirring and retention time will get a good gel plume is formed.

3:The sludge plume overflows into the drum by gravity, rotates and thickens through relative motion, increasing the speed of free water separation and sludge concentration to form a solid sludge mass.

4:The sludge falls into the gravity dewatering zone of the upper belt filter to get the second stage gravity dehydration. At the same time,the sludge equalizer is positioned and adjusted to force the sludge to be uniform in thickness and width.

5:The evenly divided sludge dropped to the gravity dehydration zone of the lower belt filter to get the third stage of gravity dehydration.At this time, the sludge solids concentration can reach over 8-10%.

6:The sludge begins to enter into the initial pressure wedge-shaped throat, initial pressure → low pressure → medium pressure→ high pressure, and squeezes and dewaters in a horizontal wave-shaped motion track.

7:The sludge cake attached to the belt filter is derived, and peeled off by a scraper and dropped into the next stage processing unit.

8:Sludge cake solid content can reach to 15-22%.

Technical character

Belt press dewatering machine with high dehydration efficiency,large sludge treatment capacity, automatic continuous operation, low energy consumption, low noise, simple structure, semi-closed structure, and easy

maintenance.It is easy to operate, understand, and learn, and you can master the entire operation process in a short time.
