Description
I. Overview
The VFS filtration system, produced with imported technology, is a new type of filtration equipment designed for the automatic continuous
filtration and continuous slag discharge of viscous petrochemical pulps. Widely used in pharmaceuticals, petroleum, chemicals, and food
industries for the treatment of high-viscosity liquids, this filter is an essential piece of equipment.
II. Working Principle
Untreated liquid is pumped into the filter cylinder from the top, and solid particles are intercepted by the wedge-shaped mesh. When the
filter cake reaches a certain thickness, the system starts the cleaning device. The cleaned filter residue is pushed to the bottom of the tank's
residue compartment. When the residue reaches the set position, the discharge valve opens to discharge the residue. The structure ensures
that the residue (with lower density than the unfiltrated liquid) does not suspend due to gravity, liquid level pressure, and filtration pressure. The
moisture content of the tank residue can reach 80% due to the combined action of gravity, liquid level pressure, and filtration pressure. When
the set residue amount is reached, the discharge valve opens for residue discharge (opening time: 1-2 seconds, or set as timed), and then the
residue is sent to a sealed storage tank by a screw feeder (optional).
