US 7,410,569 B1 · Filtration system for metalworking fluids

Abstract

A filtration system for metalworking fluids has panel filter elements arranged in cells in which the filter frames and panels are approximately parallel to one another. The filter frames are disposed such that the filter surfaces are oriented at an acute angle with respect to the longitudinal axis of the drag-out tank within which they are installed. The filter elements are constructed by affixing a microscreen filter to a wire mesh support structure. The wire mesh structure provides as much support as the perforated plates of the prior art, while featuring significant gains in effective filter area when compared with perforated plate constructions.

Dependent claims

A filtration system for metalworking fluids, comprising:

a drag-out, coolant cleaning tank having a longitudinal axis;
a mechanical conveyor system for removing solid contaminants from the tank, with said conveyor system being oriented for motion along said longitudinal axis of the tank;
a pump system for removing clean coolant from the tank and for backflushing a filter system housed within said tank;
and
a filter system mounted within said tank, with said filter system having a plurality of panel filters for receiving dirty coolant from said tank and for providing clean coolant to said pump system, with said plurality of panel filters being generally parallel to each other and oriented at an acute angle to said longitudinal axis.
