Residue sluice for filter devices, in particular for coating paint filters

摘要

The sluice for exfiltration of residue in a coating color filter plant for the recognition of a degree of pollution of an individual filter mechanism during parallel connection of the two individual filter mechanisms in a filtering unit for the filtration of coating media for fibrous material webs, comprises inlet and outlet controllable over inlet and outlet valve mechanisms, and a ventilation arrangement (30) having a ventilation opening (32) in a residue chamber (25). The ventilation opening is vertically arranged in mounting position above a connection for a flushing arrangement. The sluice for exfiltration of residue in a coating color filter plant for the recognition of a degree of pollution of an individual filter mechanism during parallel connection of the two individual filter mechanisms in a filtering unit for the filtration of coating media for fibrous material webs, comprises inlet and outlet controllable over inlet and outlet valve mechanisms, and a ventilation arrangement (30) having a ventilation opening (32) in a residue chamber (25). The ventilation opening is vertically arranged in mounting position above a connection for a flushing arrangement and is coupled with a shut-off ventilation line (33), which is connected with a throw-off- or discharge system. The ventilation line is coupled with a pipeline coupled with a catching unit (21) for the residue behind the outlet valve mechanism. The ventilation opening is arranged in the outlet valve arrangement, which is horizontally arranged in the mounting position with its through-flow direction. Independent claims are included for: (1) a coating color filter unit; (2) procedure for exfiltration of residue in coating color filter plant; and (3) procedure for recognition of a degree of pollution of an individual filter mechanism during parallel connection of the two individual filter mechanisms in a filtering unit.
