    • A stirring apparatus includes a container with a rotary stirring shaft therein. On the opposite sides of the rotary stirring shaft are mounted an upper vertical flat blade and first inclined flat blades opposite to each other. A first vertical flat blade has a sweptback blade associated therewith, and is mounted to the stirring shaft at a position under the first inclined flat blades, and a second inclined flat blade or blades and a second vertical flat blade having an associated sweptback blade are mounted to the stirring shaft at a position under the upper vertical flat blade. When the stirring shaft rotates, ascending flows of liquid to be processed along the inner wall within a vessel are generated by the upper vertical flat blade and the first and second vertical flat blades that are each associated with a sweptback blade. Descending flows of the liquid to be processed are generated by the inclined flat blades, thereby enhancing the mixing performance.
    • 搅拌装置包括在其中具有旋转搅拌轴的容器。 在旋转搅拌轴的相对侧上安装有上部垂直平面叶片和彼此相对的第一倾斜平面叶片。 第一垂直扁平叶片具有与之相关联的扫掠叶片,并且在第一倾斜扁平叶片下方的位置处安装到搅拌轴,并且安装具有相关联的扫掠叶片的第二倾斜扁平叶片或叶片和第二垂直平面叶片 在垂直平面叶片上方的位置处的搅拌轴。 当搅拌轴旋转时,通过上垂直扁平叶片和第一和第二垂直平面叶片产生沿着容器内的内部处理的液体的上升流,每个叶片与扫掠叶片相关联。 通过倾斜的扁平叶片产生待处理液体的下降流,从而提高混合性能。

    • A process for classifying plastic-containing wastes which comprises dissolving a mixture of plastics containing polyolefin-type plastics in a hydrocarbon solvent (preferably of a xylene type) at a temperature of not lower than 60.degree. C. (preferably not lower than 80.degree. C.), vacuum-evaporating the solvent of the solution to cause precipitation of the polyolefin-type plastics dissolved therein, separating and recovering the major portion of the precipitate, further dividing the resulting separated solution into the concentrated liquor of the precipitate yet remaining admixed in the separated solution and the phase of a solution hardly containing the precipitate, recycling the concentrated liquor and using again for dissolving the mixture of plastics, and removing the solvent from the phase of a solution hardly containing the precipitate so as to recover the polystyrene-type plastics. A process for classifying plastic-containing wastes by separating and recovering the precipitate of the polyolefin-type plastics from the mixture solution containing the same in the above-mentioned process, which comprises connecting in series a plurality of solid-liquid separating devices, sequentially disintegrating and dispersing the precipitate separated by the separating device at a preceding stage in the separated solution flowing out from the separating device at a subsequent stage and again separating the precipitate by the separating device at a still subsequent stage.
