PLANT FOR TREATING WORKPIECES WITH A PROCESS FLUID

摘要

An installation for treating workpieces (12) with a processing fluid (14) has a workpiece application zone (16). The installation (10) contains a pipe system (28) for circulation of the processing fluid (17) which is used in the workpiece application zone (16). In the installation (10) there is a cleaning device (30) for the processing fluid (14) circulated by means of the pipe system (28). According to the invention the cleaning device (30) includes a separating device (58) supplied with processing fluid (14) via an inlet opening (88) for particles of dirt (86) entrained in the processing fluid (14). By means of an overflow opening (90) connected to the workpiece application zone (16) via a pipe section (29) of the pipe system (28) the separating device (58) dispenses processing fluid (14) from which particles of dirt (86), in particular particles of dirt (86) having a grain size G which exceeds a characteristic value a Max, are removed. At an underflow opening (92) the separating device (58) provides processing fluid (14) which contains the particles of dirt (86) removed from the processing fluid (14) at the overflow.
