Description

Sludge Dewatering Belt Filter Press is a common type of mechanical dewatering equipment. Which is widely used for efficient dewatering of sludge from municipal, industrial, mining and aggregaes wastewater treatment plants. Especially suitable for dewatering of tailings mud such as iron ore, copper ore, lead-zinc ore, fluorite ore, bauxite or rare earth ore; Dewatering operations such as ore dressing wastewater, sand washing mud or wash plant sludge.
The slurry is sandwiched between two tensioned porous belts, by passing those belts through a serpentine of decreasing diameter rollers. Water is then removed from the slurry and a solid material is produced.

Working Principle

1. Thickener dehydration: chemical pretreatment stage
The belt filter press has higher requirements for flocculation effect. This machine uses a unique dosing mixer to achieve rapid flocculation and achieve the best flocculation effect.
2. Gravity dehydration: gravity concentration dehydration stage
The sludge is evenly fed into the mesh belt through the cloth bucket. The sludge runs forward with the filter belt. The free water flows into the water tank through the filter belt under the action of its own weight. The main function is to remove the free water in the sludge, so that the fluidity of the sludge is reduced and ready for further extrusion.
3. Low/medium pressure dewatering: wedge preloading dewatering stage
After gravity dewatering, it is still difficult to meet the sludge flowability requirements of the press dewatering section. After this stage of slight extrusion dewatering, the sludge is smoothly pressed and dewatered.
4. High pressure dehydration: the depressurization stage of the clamp press
The filter cake is repeatedly pressed and sheared around the press roll by the upper and lower filter belts. A large amount of capillary action water is removed to gradually reduce the moisture of the filter cake.

Belt Press Applications

Belt filter presses are designed for dewatering applications where sludge is particulate, include various types of industrial wastewater sludge, such as sand-making mud, washed sand mud, mine tailings, piling mud, river silt, etc. They are pumped to the deep cone thickener, the flocculant is added to the thickener tank, and the concentration of the sludge in the thickener is increased by 60%-70% under flocculation and gravity precipitation. Then sent to the belt filter presses, under the action of a gravity zone, a wedge zone, and a pressure zone , the sludge cake with water content of less than 20% is formed and the overflow clean water will be re-processing.
