DUY Vacuum Belt Squeeze Filter

Structure and working principles:

Structure:

      The equipment consists of a belt vacuum dewatering section, a crawler belt covered pressurizing section and a squeezing section. It is composed of feeding hopper, rubber belt, vacuum box, cake washing device, crawler belt cover pressing device, vacuum press roll device, filter cloth correction device, driving device, filter cloth cleaning device, frames and other components. It uses filter cloth as filter medium to make full use of slurry gravity and vacuum suction to achieve the effect of solid-liquid separation.

Working principle:

      The annular rubber belt is driven by a reducing motor run continuously on the vacuum box, and the filter cloth which laid on the rubber belt run with it synchronously. The slurry is evenly distributed on the filter cloth by the feeding hopper. When the vacuum box is connected to the vacuum system, vacuum area formed on the rubber belt, the filtrate penetrates the filter cloth and is collected by the transverse grooves on the rubber belt and flows into the vacuum box through the holes in the center of the rubber belt, while the solid part is intercepted and becomes cake on filter cloth.The washed filter cake moves forward with the filter cloth and enters the pressurized area covered by the crawler belt, and continues to be dewatered under the double action of the pressing force of the pressure rollers and the vacuum suction force.

      After the filter cake enters the pressing area, the filter cloth is driven by the reducing motor continues to run synchronously forward, the filter cake is wrapped in the upper and lower filter cloths. Under the triple action of pressing and shearing force, vacuum suction and rolling force, maximum remove water from the cake, finally the filter cake is discharged through the upper and lower discharge devices of the pressing drive roller. After the cake has been removed, the filter cloth is cleaned and renewed by the upper and lower flushing cleaning device, and then re-enters the filtration area after passing through a set of support rollers and corrective device, and then enters the next filtration cycle.V
