Abstract
An improved coolant cleaning method, system, and apparatus, are provided through the use of a filter disk assembly that defines and is rotatable about an axis of rotation of the disk, for removing particulate matter from a fluid flowing through the filter disk assembly in a direction substantially parallel to the axis of rotation of the filter disk assembly. A coolant cleaning system includes such a filter disk assembly, connected in fluid communication with an apparatus for circulating a flow of fluid through the filter disk assembly in a direction substantially parallel to the axis of rotation of the filter disk assembly. An apparatus for circulating a flow of fluid may include a dirty fluid reservoir, a conveyor for removing chips and particulate matter from the dirty fluid reservoir, a clean fluid reservoir, with the filter disk assembly providing the sole fluid communication path between the dirty and clean fluid reservoirs, and a fluid supply system having a pump for circulating fluid from the clean fluid reservoir through the disk filter assembly. Several filter disk assemblies may feed into a single clean fluid reservoir to achieve high volume flow rates of clean fluid. Alt…
