Rotary Vacuum Drum Belt Filter for Belt Discharge

Rotary vacuum drum belt filter is made to provide solid-liquid separation solution in vacuum (negative pressure) operation. It discharges the filter cake across the folding belt device and carries out cleaning and regeneration of filter cloth. It is widely used in industries of chemicals, pharmacy, environmental protection, etc.

Rotary vacuum drum belt filter discharges filter cakes by belt-fold device when achieving solid-liquid separation in vacuum operation.

There are some limits to the suspension to be filtered, and if your suspension is with one of the following situations, then it is not suited with rotary vacuum drum belt filter.

• Solid content is too low, and the filter cake formation is slow. (Rotary drum stays in the suspension for two minutes, and filter cake thickness is less than 5 mm).
• Suspension has large proportion of solid which leads to solid settling rate larger than 12 mm/s.
• Suspension has high viscosity of the solidify so that it easily blocks the filter cloth and makes the cloth difficult to regenerate.
• Suspension with heterogeneous solid particle size brings about filter cake with obvious condensability.
• Suspension with unstable chemical composition and properties.

Feature

• High-degree automation.
• Continuous operation.
• It makes for reclaiming of filter cloth.

Working principle
Filter cake discharging method and cloth regeneration way are the two differences between ordinary drum filter and rotary vacuum drum belt filter.
Rotary vacuum drum belt filter discharges the filter cake across the folding belt device (adjusting roller, rotating roller, guide roller), with filter cloth moving in the meanwhile (driven by the drum rotation). The filter cloth regenerates and goes into next operation cycle through the flushing pipe.
