Apparatus for separating off amalgam particles

摘要

An apparatus for separating off amalgam particles from the waste waters produced in a dental practice contains a vertical amalgam separation cyclone (24) and an air separation cyclone (22) connected upstream of this. A circulation pump (40) continuously circulates a base water stream through both these cyclones. Via a free-jet nozzle (36), amalgam particle-containing waste water is fed to this base stream. An overflow (58) or a magnetically operated valve (400), controlled in a level-dependent manner, serves for taking off a corresponding amount of purified water from the circulation. On the amalgam separation cyclone (24) is mounted an amalgam collecting vessel (26) which receives water highly enriched with amalgam particles and, after sedimentation of these particles, feeds back purified water to the amalgam separation cyclone (24). For this purpose, the amalgam collecting vessel (26) is equipped with a special deflector piece (76).
