Working Principle of Vacuum Disc Filter -

When the slurry enters the filter through the inlet chamber, it is equally distributed down the length of the vat. The pulp mat starts to form under the influence of gravity, ensuring optimal dewatering qualities. The filtrate is discharged into the corresponding filtrate channels in the central shaft through the open-grid type sectors. The spinning shaft is connected to the filtrate valve, which opens and shuts the channels to the vacuum created by the barometric legs. As the filtrate enters the valve, it can be switched between clear, cloudy and super-clear filtrate if necessary. Once the sectors have emerged from the suspension and have been drained, the pulp mat is dewatered under vacuum. The pulp mat is separated using a water iet employing the knock Off Shower nozzles above sectors, and it is then discharged through chutes inside the vat and sent in to a screw conveyor .An oscillating nozzle cleans the mesh of filter before commencing the filtering procedure.

Advantages of Aspire Disc Filter -

• CENTER SHAFT : Aspire Disc Filter has stable & sturdy center shaft that enables the disc filter to function smoothly
• EXCELLENT FILTRATION : It is easier to maintain clean filtrate when the filter is internal volumes are smaller. Disc Filter has small internal volumes in the shaft, filtrate valve, and sectors to offer the highest quality filtrate possible. The clear filtrate can be divided into clear and super clear filtrates, depending on the process requirements.
• SECTORS & FILTERING MEDIA : Each disc is composed of twenty open-grid type sectors that are connected to corresponding filtrate channels in the shaft. The design of the open-grid sector reduces the likelihood of pulp and debris accumulating inside it by providing over 90% open space. This design allows for a spray water iet to pass through the open sector and clean the filter media from both the inside and outside which enhances its effectiveness.
• FLEXIBLE INSTALLATION : The clockwise and counterclockwise rotations of the Disc Filter are both supported by its design. This gives planners more options when laying out the mill, for instance, if a series or parallel operation mode is required.
