Rotary drum filter

waterdiscvacuum

The rotary vacuum filter is composed of discs of individual sector. Each sector is a independent filter unit, A filter chamber is formed on the sector by a filter cloth. The filter disc is driven by a motor through the decelerator and the open gear drive. The filter disk turns clockwise in the slurry hopper, at adsorption area, the slurry in filter chamber will form to be the cake due to the effect of vacuum suction on the sectors. The Agitator rotates to prevent solid precipitation. While away from the slurry surface, the cake continue to dewater under vacuum suction. The filtrate pass through the filter cloth and tube, to discharge from the distribution. The cake is discharged from the discharge zone by the reverse blowing and discharged into the discharge hopper. The full operation process is continuously in circulation.
