The rotary drum vacuum filter is a continuous filter for solid-liquid separation in industrial production. The filter cloth, wrapped around the rotary drum, plays a crucial role in rotary drum vacuum filtration. The choice of filter media depends on the application, as different materials and weaves can affect the filtration efficiency and durability of the filter cloth. Our fabric technologies were developed to retain the finest particles together with having the highest possible throughput. The unique filter surface makes for good cake release and easy cleaning.
- Material: PP, PE.
- Weaving Methods: Plain, Twill, Satin.
- Cloth Codes Most Widely Used: ES-D-Pr, ES-D-St.
Description
Work Principle of Vacuum Rotary Drum Filter
The filtering surface vacuum drum filter through a continuous rotation of the drum, and connected to the drum room, the distribution of the rotating drum filter surface partition, when filtering surface operation to an area (suction), filtering operation can be performed.When it is transferred to another area (dry), can be carried out on the filter cake drying.Again to other area (washing,drying and discharging, filter cloth blanket), can be corresponding to the filter cake washing, secondary
drying, and through the discharging device of filter cake to discharge.Such as filtering slurry viscosity big, need to washing of filter cloth, after discharge, by installing the filter on both sides of the nozzle to washing of filter cloth, filter and then on to the next cycle.Drum rotation time, the cycle again.Complete the filtration, drying, washing, drying,unloading and regeneration of filter cloth and so on.In different regions at the same time, mechanical operation of the work, and form a continuous filtration.
Applications
- Mining and Mineral Processing: For separating solids from slurries.
- Wastewater Treatment: Used in the filtration of water, removing suspended solids and other impurities.
- Food and Beverage Processing: For filtering liquids like juices, oils, and broths.
- Chemical Industries: To separate solids from chemical slurries or solutions.
