Feed channel comprising an expansion body for charging the separator electrode of a wet overspray separator device

摘要

The invention relates to a separator unit (1) that is intended for use in a separator device for overspray in an installation for coating objects , being known to comprise a panel- shaped separator electrode (3) on which at least one separator surface is formed for the overspray. A feed device (2) ensures that a separator liquid can be fed to the separator surface of said separator electrode (3). It comprises a channel (4) that can be filled with the separator liquid , as well as a removal device with which separator liquid can be removed from said channel (4). The latter comprises a shape -changing , flexible and/or elastic expansion element (7) arranged in said channel (4) , which at least partially delimits a closed cavity (30). A further component of the removal device is a pump device (9) with which a pressure medium can be pushed into the closed cavity (30). As a result of the volume expansion of the closed cavity (30) when "pumping up" said expansion element (7) , separator liquid is displaced over the edges of the channel (4) and from here it can be conducted onto the separator surface of the separator electrode (3) in a suitable manner.
