Abstract: A digester for fluorescent tubes is formed of a container in the shape of a funnel having an open bottom adapted to be inserted in a bunghole in a storage drum. A tube for receiving fluorescent tubes opens into the container at one side. Within the container is a rotating blade which passes beneath the opening of the tube for breaking up fluorescent tubes, and similar materials. The axis of the tube is arranged in a plane tangential with respect to the axis of rotation of the blade and the tube slopes downwardly in the direction of rotation of the blade. The blade has a rearwardly and downwardly sloping surface for creating a downward draft of air within the funnel to prevent phosphorus and mercury vapors from escaping outward. A slightly downwardly sloping shelf is arranged beneath the tube and below the plane of rotation of the blade, by a distance at least substantially equal to the length of the terminal prongs of a fluorescent tube. The leading edge of the blade forms an acute angle with the radius drawn from the axis of rotation to the top of the leading edge.

Abstract translation: 用于荧光灯管的蒸煮器由具有开口底部的漏斗形状的容器形成，适于插入存储鼓中的孔中。 用于接收荧光管的管在一侧开口进入容器。 在容器内部是旋转的叶片，其通过用于破坏荧光管的管的开口下方和类似的材料。 管的轴线布置在相对于叶片的旋转轴线切向的平面中，并且管沿叶片的旋转方向向下倾斜。 叶片具有向后和向下倾斜的表面，用于在漏斗内产生向下的空气流，以防止磷和汞蒸气向外逸出。 稍微向下倾斜的搁架布置在管下方并且在叶片的旋转平面下方至少基本上等于荧光管的端子尖端的长度的距离。 叶片的前缘与从旋转轴线到前缘顶部的半径形成锐角。
