Vacuum filters are a type of continuous solid-liquid separation equipment widely used in industrial separation processes. Its core principle is to use the negative pressure environment established inside the system to drive the suspension through a specific filter medium. During operation, the slurry is introduced into the device, and under the action of vacuum suction, the liquid phase components are sucked out through the filter layer, while the solid matter is trapped and gradually accumulates on the surface of the medium to form a filter cake.
The key feature of this type of device is that it can achieve continuous or semi-continuous automated operation of separation, washing, dehydration and unloading, and is particularly suitable for processing large-scale, continuously operating material systems. The rotating drum structure combined with a precise distribution valve is the basis of its typical working cycle, ensuring that the filtration process is repeated under set conditions. Vacuum filtration technology plays a vital role in many process industries due to its processing capacity, consistency of operation and adaptability to different materials.
