DEVICE FOR DRY GRANULATION OF LIQUID SLAG

The invention relates to metallurgy, and particularly to devices for processing of slags of ferrous and nonferrous metallurgy to granules. The technical result from the use of the propose invention consists in the increased efficiency of device operation due to guaranteed high-performance obtaining of drops-granules from the flow of molten slag, simplified design and enhanced reliability of the device operation on the whole. The device additionally included a slag flow divider (4) and a disperser-tray (5), a granulator of molten slag (2) with a cooling system is made in the form of at least three hollow drums (7) rotating in the opposite direction with water circulating inside the walls, whereas the drums are located one under another with an "S" gap between the walls of the rotating drums both in the vertical plane and with differently directed next but one displacement "m" in the horizontal plane so that any drop-granule of molten slag falling on the rotating surface of the downstream drum passes before its fall, together with the rotating surface of the upstream drum, passes a path with the length of no less than 1/3 of the perimeter of its circle; the disperser-tray (5) is made with the curvilinear guiding surface with streams-flutes located thereon in the form of divergent sheaf to the tray edge with the said disperser-tray turned with its internal curvilinear surface toward the flow of molten slag falling on it through the divider (4), whereas in the place of falling of slag drops-granules from the rotating drums, and scrapes (8) with cutting cutting edges are located towards rotation at a tangent to the external drum surface. Изобретение относится к металлургии, в частности к устройствам для переработки в гранулы шлаков чёрной и цветной металлургии. Технические результаты от использования предлагаемого изобретения заключаются в повышении эффективности работы устройства за счёт гарантированного высокопроизводительного получения капель-гранул из потока расплавленного шлака, в упрощении конструкции и в повышении надёжности работы устройства в целом. В состав устройства дополнительно включены делитель (4) потока шлака и лоток-диспергатор (5), гранулятор расплавленного шлака (2) с системой охлаждения выполнен в виде не менее трёх вращающихся во встречном направлении полых барабанов (7) с циркулирующей внутри стенок водой, при этом барабаны расположены один под другим с зазором "S" между стенками вращающихся барабанов как в вертикальной плоскости, так и с
