Abstract
A coolant purification system for purifying and removing particles from the coolant used in machining operations. The system uses a rare earth magnetic separator in combination with bag-type filters and deep level filters that are arranged in sequences so that the filters that tend to clog more frequently due to the removal of small particles will not be clogged by particles that are easily removed by coarser filters of this system.
Claims20
A system for recovery and cleaning of foreign particles from a machining liquid coolant comprised of a coolant storage tank for storing coolant, a machining station wherein machining operation is performed, and a coolant circulating and purifying line for circulating coolant from said coolant storage tank to said machining station and back to said coolant storage tank, a rare earth magnetic filter for separating magnetic particles from said coolant and disposing of said separated magnetic particles to avoid reentry into the circulated coolant, and a mechanical filter for filtering said foreign particles from said coolant, said mechanical filter comprising at least one bag type filter and at least one deep level type filter, said coolant circuit and purifying line circulating coolant in a series relationship through said magnetic filter and said mechanical filter.
