Rotary vacuum filter drum

1.1 ROTARY VACUUM DRUM FILTERS The Rotary Vacuum Drum Filter belongs to the bottom feed group and is one of the oldest filters applied to the chemical process industry. Therefore rotary vacuum drum filters are certainly used in to the best part of solid liquid separation process. The Figure 1, shows the basic structure of the rotary vacuum drum.

Rotary Vacuum Drum Filters process slurry and discharge cake in a continuous process. RVDFs can be used in waste water treatment, sludge dewatering, chemical manufacturing, the pharmaceutical industry, cosmetics, mineral mining and refining, and the food processing industry. It is ideal for a slurry with variable cake thickness, moisture content, and stickiness.

Rotary Vacuum Filters

Slurry sits in a tank with a partially submerged drum. As the drum rotates into slurry, vacuum pulls the liquor through the industrial filter media, trapping the solid particles on its surface, forming a cake. As the drum continues to travel through slurry, the cake thickens.

As the drum emerges from the slurry tank, spray bars wash the cake, allowing air, water, and the remaining liquor to travel through the drum section into piping, through the valve, and into a vacuum receiver.

Rotary Vacuum Filter In Sugar Industry

As the rotary vacuum drum filter begins to rotate facing the ceiling, it enters the drying zone. The drum remains under vacuum, pulling air through the cake for more dewatering.

The drum then reaches its discharge zone as it roll to the position just over the slurry tank. Drum filters discharge in a variety of ways; scraper discharge, belt discharge, string discharge, roll discharge, and pre-coat discharge.
