ABSTRACT:
A compact cyclonic filter assembly used for separating unwanted debris from a fluid. The cyclonic filter assembly uses the centrifugal forces to separate large pieces of debris from the fluid and a filter to separate the remaining unwanted debris from the fluid. The present invention can be contained in a compact single housing which may be disassembled for easy cleaning and replacement of parts. The cyclonic filter assembly of the present invention has a vertically oriented cylindrical tube which receives a tangential injection of the debris laden fluid. The tangential injection causes the fluid to circulate around a cylindrical vortex finder which is inside of and coaxial with the tube. The centrifugal forces acting on the debris causes the debris to move outward away from the center of the vortex. The vortex finder has an opening which pulls in the relatively clean fluid near the center of the vortex while the debris laden fluid settles into a collection chamber below the cylindrical tube. The vortex finder carries the relatively clean fluid to a filtration chamber which preferably encircles the cylindrical tube. The filtration chamber houses a filter element which is used to extract the remaining unwanted debris from the fluid before it exits the cyclonic filter assembly. The filter element used in the present invention is a standard filter bag that not only acts as a filter element in the filtration chamber, but also extends into the collection chamber to act as a debris collection bag.
