rotary Drum Vacuum filter

Rotary vacuum drum filter (RVDF) by Ankita-Technologies is best suited for continuous separation of solids from slurries & suspensions. Ankita Technologies is a leading Rotary vacuum drum filter (RVDF) suppliers from India. Ankita Technologies is a global provider of high-quality Rotary vacuum drum filter (RVDF). The A-T Rotary Drum filter is capable of handling wide range of complex multi stage applications like filtration, cake washing, drying & extraction, normally used in liquid solids separation. Its unique, multi-cell design provides a very high filtration rates than a conventional discharging filter, with an efficient liquor extraction, all this under gas tight drum hood.

The slurry level is maintained in the trough during continuous drum filter operation. An agitator keeps the slurry in the suspended form. The drum is partially submerged in the slurry to be filtered. As the drum rotates, rotary drum vacuum draws the liquor through the suitable filter media causing the solids to deposit on the filter medium, thus forming a cake of uniform thickness.

Drum RPM can be controlled using a variable frequency drive. As the drum rotates, the filter cakes are washed, dried & finally discharged. The cake discharge can be done in a variety of ways; scraper discharge, roll discharge, precoated discharge, belt discharge & string discharge. The Drum vacuum filters discharge mechanism mainly depends upon the characteristics of cake. Filter cloth washing & blowback at the cake discharge can be provided as per process conditions.
The A-T Rotary vacuum filter performance depends on the following parameters – Solid concentration, the Particle size distribution of solids, Drum rotational speed, and Vacuum.

Rotary Vacuum Drum Filter (RVDF) has typical applications in high-volume filtration for continuous or batch mode of operation. The solid-liquid filtration is carried out using a continuous rotating drum kept under constant vacuum. The system facilitates efficient slurry filtration, cake-washing, dewatering and/or clarification.

Rotary filters are machines for separating a solid-liquid mixture. Rotary filters are ideal if your application requires robustness, minimal footprint, and uses solvents, Filtres systems are the best continuous vacuum filtration solutions on the market. It is on the drum that the separation takes place: it is partially submerged in the tank.

A Rotary Vacuum Filter Drum consists of a cylindrical filter membrane that is partly sub-merged in a slurry to be filtered. The inside of the drum is held lower than the ambient pressure. As the drum rotates through the slurry, the liquid is sucked through the membrane, leaving solids to cake on the membrane surface while the drum is submerged. A knife or blade is positioned to scrape the product from the surface.

As the Rotary Drum Vacuum Filter (RDVF) 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.

As the Rotary Drum Vacuum Filter / Filtration begins to rotate facing the ceiling, it enters the drying zone. The drum remains under vacuum, pulling air through the cake for more dewatering.

Rotary Drum Filters are perforated rotating drum of ample free area fitted with variety of filter media for the type of dust and waste. The material deposited on the filter media is sucked off with smooth sliding nozzles connected to a powerful suction blower through a cyclone and bag filters.

Rotary Filter / Filtration provides twice the amount of nozzles for efficient and faster collection of micro dust. The micro dust is continuously removed through Cyclone separator/compactor by Ventilator Fan. The higher size filters are provided with 2 Ventilator fans to improve cleaning efficiency.
