Product Description

For over 10 years, Doyen commits in the design and manufacturing all types of environmentally-friendly belt filter press for many customers from different industries all over the world.

Characteristics of DOYEN type of belt press:

One-time investment, long-term use; Prompt, reliable and good service guarantee.

Customized design and high quality parts ensure a stable running and low maintenance cost (Belt lifetime can as long as 6-9 months)

Larger filtration area contributes to a larger capacity and lower solid content of filter cake!

Humanized operation (with PLC control), Low labor cost.

Unique design can save water consumption and electricity cost.

 

WORKING PRINCIPLE

For sludge dewatering which need a pre-floculation: After mixing with the prepared flocculation in the dynamic and static mixer, the small particles solids in the concentrated sludge would form bigger size of flocculated sludge and the free water is separated. Flocculated sludge is conveyed to the belt then it further goes to the gravity dewateugh the decreasing diameter rolls. Under the extrusion and shearing force, the solid and liquid is separated. Finally filter cake with expected low moisture content is discharged.ring area. Under the gravity, free water would fall on the tray, and the rest sludge would be nipped between two belts. Then it would further goes to the wedge zone for pre-filtration, and then to low pressure zone and high pressure zone thro

For wet pulp dewatering:  After collecting the wet pulp, the pulp are conveyed to the feeding tray of belt press, then the wet pulp would be nipped between the two belts and run through 3 sets of dewatering roller. Finally the filter cake with low moisture content would be discharged.
