Mechanical Self Cleaning Filter Vessel

Precision Filtration mechanically cleaned filter system designed to handle to filter 20 micron and larger in various industries where high particle contect, viscous and sticky liquid. The system contains a cylindrical filter screen, liquid flow through the screen and dirt retain on the inner surface of the screen (with define filtration opening). Clean disc moving up and down continuously to remove the dirt, and discharge from drain valve at periodical time. Clean disc made by special grade of Teflon disc has a doctoring and wiping edge, both edges are pressed tightly against the screen by mechanical loading. Precision Filtration Self Cleaning Filter Systems Operation Principle Raw liquid enters via the inlet and travels from the inside to the outside of the filter media, contaminants are retained on the inside, clean filtered liquid exits via the outlet. The cleaning disk travels down and then back up by the use of a pneumatic cylinder. The flow pattern concentrates contaminants at the bottom of the filter housing and the concentrated solids are periodically purged. Purging lasts less than one second, releasing only the volume of the collection chamber and avoiding process interruptions. Self Cleaning filters are ideal for continuous flow (and therefore batch) applications. In every case, these filters offer significant advantages over alternative filter designs.
