Abstract
1. Устройство для направленного сухого гранулирования шлака, причем устройство включает ротационный распылительный гранулятор, имеющий центральную линию оси вращения; устройство для подачи струи шлака, и регулятор положения, в котором точка падения струи шлака на ротационный гранулятор для шлака из устройства для подачи струи шлака смещена в сторону от центральной линии и неконцентрична относительно оси вращения ротационного гранулятора, причем ротационный гранулятор включает один компонент из стакана, диска или кольцеобразной детали, приспособленный для вращения вокруг осевой линии, и, причем устройство дополнительно включает датчики для определения прогнозируемой точки падения струи шлака; причем регулятор положения дополнительно включает сравнивающее устройство для сравнения определенной прогнозируемой точки падения струи шлака с предварительно заданным положением точки падения, и выходное устройство для подачи выходного сигнала на исполнительный механизм, чтобы переместить гранулятор в ответ на результат сравнения.2. Устройство по п. 1, причем устройство дополнительно включает исполнительный механизм для перемещения ротационного гранулятора относительно устройства для подачи струи шлака.3. Устройство по п. 2, в котором исполнительный механизм включает подвижную фурму.4. Устройство по п. 3, в котором фурма включает пустотелый воздуховод и сильную струю воздуха.5. Устройство по любому из пп. 1-4, в котором ротационный гранулятор смонтирован на станине.6. Устройство по п. 5, в котором станина дополнительно включает выходные отверстия для струи воздуха.7. Устройство по любому из пп. 1-4, причем устройст1. Device for directional dry granulation of slag, and the device includes a rotary spray granulator having a Central line of the axis of rotation; a device for feeding a slag stream, and a position regulator in which the point of incidence of the slag stream on the rotary granulator for the slag from the device for feeding the slag is offset from the center line and non-concentric with respect to the axis of rotation of the rotary granulator, and the rotary granulator includes one component from a glass, a disk or an annular part, adapted for rotation around an axial line, and, moreover, the device further includes sensors for determining the predicted point of incidence of the slag stream; moreover, the position controller further includes a comparison device for comparing a specific predicted point of incidence of the slag stream with a predetermined position of the point of incidence, and an output device for supplying an output signal to the actuator in order to move the granulator in response to the comparison result. The device according to claim 1, wherein the device further includes an actuator for moving the rotary granulator relative to the device for supplying a stream of slag. 3. The device according to claim 2, in which the actuator includes a movable lance. The device according to claim 3, in which the lance includes a hollow duct and a strong stream of air. The device according to any one of paragraphs. 1-4, in which the rotary granulator is mounted on a bed. 6. The device according to claim 5, wherein the bed further includes outlet openings for a stream of air. The device according to any one of paragraphs. 1-4, and the device
