DFX Series Scraping Self-cleaning Filter
Introduction
DFX series self-cleaning filter , is the high efficiency self-cleaning filter independently developed by LIVIC. Removing the impurities particles on the filter element outside by mechanical scraping, it continuously filters on-line.DFX filter is designed for fine and accurate filtration ranging from 50-500micron. It can avoid extruding and breaking the impurities and is capable of the filtration for water and liquids of viscosity up to 800000cps. DFX filter is designed and manufactured per LIVIC’s high performance, high quality and high reliability standard. It is a world-class quality filter.
The conventional filters get clogged frequently when filtering the viscous liquid and removing the soft impurities. The customers have to select larger filters and clean the filter manually and frequently, which means expensive investment, hard work, valuable liquid loss. DFX filter solves these kinds of problems by its advanced self-cleaning. It always keeps the filter element clean, discharges waste liquid with high impurity concentration, reduces the liquid loss. When filtering the viscous liquids such as dirty water, adhesives, resins, polymers and oil, DFX filter works more efficiently. DFX filter is taking place fo vibrating screen, bag filter, basket filter and some kind of back-flushing filter by its technical advantages and low running cost.
Working Principle
The liquid enters the filter from the inlet(1), flows through the filter element(6) from outside to inside. The filter element bottom is connected to the outlet(2), through which the liquid flows out. After the filter element captures the impurities, the cleaning action is triggered by the preset time or differential pressure value. The gear motor(4) drives the scraping blades(7) to rotate and remove the impurities on the filter element outside surface. The impurities moves off along the blades and falls down to the filter bottom. The rotating plates push the gravity impurities into the collection chamber(5). The impurities are collected at the filter bottom and in the collection chamber. The discharging valve opens per the preset time and purges the waste liquid with high impurity concentration through the drain outlet(3), the waste liquid can be reclaimed if necessary.
