ABSTRACT:
An amalgam solids collecting apparatus of the type for collecting an accumulation of a generally separable mixture of liquids and solids, including amalgam solids, and separating the solids from the liquids. The apparatus is connectable to a source of the mixture and is connectable to a vacuum source. The container has an interior area defining a collection portion therein and has an inlet port that communicates with the interior area of the container. The inlet port is couplable to the source of the mixture and the inlet port receives the mixture therethrough. The accumulation of the mixture is contained within the interior area with the headspace above the accumulation. The container has an outlet port with a second aperture therein that communicates with the interior area and that is located above the accumulation. An outflow tube extends through the outflow port, and the outflow tube has a first opening within the container and a second opening exterior of the container. The outflow tube is movable relative to the container between a raised position and a lowered position. In the raised position, the first opening is within the headspace above the accumulation of the mixture. In the lowered position, the first opening of the outflow tube is positioned within the accumulation and above solid particles that have settled from the accumulation to the bottom of the container. The outflow tube is connectable to a vacuum source to create a partial vacuum within the interior area of the container when the outflow tube is in the raised position and to withdraw the liquid from the container when the outflow tube is in the lowered position and when the solids are substantially separated from the liquid so the amalgam solids remain in the container.
