High Efficiency And Stability Belt Filter Press For Sludge Dewatering Compact Structure Smooth Operation

High Efficiency and Stability Belt Filter Press Compact Structure Smooth Operation

Brief Description

This belt filter press is specifically designed for industrial solid-liquid separation. The modular layout facilitates installation and maintenance. The equipment performs excellently in continuous operation, producing a low moisture content in the filter cake and ensuring smooth discharge. It is suitable for sludge dewatering in industries such as chemical, papermaking, and metallurgy, effectively improving production efficiency and reducing subsequent disposal costs. Its low operating noise and low energy consumption make it an ideal choice for modern factories to achieve green production.

Product Overview

The DNY belt filter press is an industrial solid–liquid separation machine independently designed and manufactured by our factory. Equipped with an S‑shaped filter belt path, it applies gradual, gentle pressure loading and unloading to sludge, delivering uniform dewatering and low cloth wear. It performs reliably for both organic hydrophilic materials and inorganic hydrophobic materials, and excels in sludge dewatering for chemical processing, mining, and water treatment facilities. Filtration relies on dual filter cloths and belts running through a precision roller system: fed with sludge or slurry, it continuously splits the stream into clear filtrate and high‑dryness solid cake. Thanks to its extended settling zone, this press series boasts proven performance and rich operational experience in dewatering diverse material streams.

Working Principle

DNY belt filter press integrated concentration and dehydration device can be divided into four basic stages : 
Sludge flocculation: sludge must go through the flocculation process before dewatering. Flocculation refers to the pretreatment of suspended solids with a flocculant. Flocculant and sludge are mixed by stirring, and the solid particles in the suspension system are bonded to produce agglomeration, so that the solid phase and the liquid phase are separated. At the same time, a small amount of coagulant aid is added to improve the coagulation effect.
Gravity dewatering: In order to reduce the fluidity of sludge more effectively before pressing, more free water must be removed. The filter belt has an upper inclination angle. The friction coefficient of sludge, free water and filter belt is different. The sludge moves up with the filter belt, and the free water is removed. The sludge is evacuated and evenly distributed on the surface of the filter belt to further enhance the dewatering effect.
Pressing dewatering: after gravity dewatering, with the movement of the filter belt into the wedge pressure section between the upper and lower filter belt, pre-dewatering, and then into the ' S-shaped pressing area, due to the shear force generated by the shear force of the sludge with the filter belt in the multi-silver phase bending, thus the internal free water. 
Filter belt cleaning: It is composed of a sprayer, a cleaning water receiving box and a cleaning cover. When the filter belt of the belt filter press travels, it continuously passes through the cleaning device, and is impacted by the pressure water ejected from the sprayer. The material remaining on the filter belt is separated from the filter belt under the action of pressure water, so that the filter belt is regenerated to prepare for the next dehydration process.
