Uniform Pressing Multi Stage Belt Filter Press For Sludge Smooth Operation Durable Filter Belt

Uniform Pressing Belt Filter Press Smooth Operation Durable Filter Belt

Brief Description

This belt press achieves uniform dewatering through multi-stage pressure rollers, resulting in consistent sludge cake thickness for easy subsequent processing. The machine operates smoothly with minimal vibration, making it suitable for sludge or residue reduction treatment in industries such as chemical, papermaking, and food processing, ensuring continuous production.

Product Overview

DNY belt filter press is an industrial machine, designed and manufactured by our factory. It has S-shaped filter belt, so the pressure of sludge is gradually increased and eased. It is suitable for the dewatering of organic hydrophilic materials and inorganic hydrophobic materials , particularly the dewatering of sludge in the chemical industry, mining and water treatment. The process of filtration is primarily obtained by passing a pair of filtering cloths and belts through a system of rollers. The system takes a sludge or slurry as a feed, and separates it into a filtrate and a solid cake.Due to lengthening the settling zone, this series of press filter has rich experience in filter pressing and dewatering of different types of materials.

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.
