(54) СПОСОБ ВОЗДУШНОЙ СЕПАРАЦИИ СЫПУЧЕЙ СМЕСИ(54) METHOD FOR AIR SEPARATION OF BULK MIXTURE
ГR
Изобретение относитс к способам воздушной сепарации сцпучих материалов, например зерна, и может быть использовано в мукомольно-элеваторной, комбикормсгеой, химической и других отрасл х промышленности , а также в сельской хоз йстве.The invention relates to methods for air separation of sintering materials, such as grains, and can be used in milling, grain elevator, feed mill, chemical and other industries, as well as in rural households.
Известен способ воздушной сепарации сыпучей смеси, включаюш.ий подачу смеси на наклонную поверхность и воздействие на смесь воздушного потока 1 .There is a method of air separation of the bulk mixture, including the supply of the mixture on an inclined surface and the effect on the mixture of air flow 1.
Недостатком известного способа вл етс невысока производительность и низкое качество сепарации в результате недостаточной степени расслоени материала при прохождении его на наклонной поверхности и малой степени проницаемости смеси воздушным потоком.The disadvantage of this method is the low productivity and poor quality of separation as a result of insufficient separation of the material during its passage on an inclined surface and the low degree of permeability of the mixture by air flow.
Цель изобретени -повышение качества и производительности процесса сепарации .The purpose of the invention is to improve the quality and productivity of the separation process.
Цель достигаетс тем, что по способу воздушной сепарации сыпучей смеси, включающему подачу смеси на наклонную поверхность и воздействие на смесь воздушным потоком , смесь подают на наклонную поверхность а виде пучка с углом раскрыти The goal is achieved by the method of air separation of a granular mixture, which includes feeding the mixture to an inclined surface and exposing the mixture to airflow, feeding the mixture to an inclined surface and in the form of a beam with an angle of
15-20°, а воздушный поток направл ют вдоль этой поверхности снизу вверх.15-20 °, and the air flow is directed along this surface from bottom to top.
Проницаемость струи материала определ етс углом раскрыти tf. Чем, больше этот угол, тем больше проницаемость. Однако увеличение yглatf более определенного значени приводит к значительной неравномерности воздействи воздушного потока на однородные частицы материала и снижению эффекта сепарации.The permeability of the material stream is determined by the opening angle tf. The greater the angle, the greater the permeability. However, an increase in more than a certain value leads to a significant non-uniformity of the effect of the air flow on homogeneous particles of the material and to a decrease in the effect of separation.
Опытно установлены оптимальные пре10 делы угла раскрыти d 15-20°. Уменьшение угла ot меньше 15° или; увеличение его больше 20° снижает эффект сепарации. При этом если слой материала движетс по наклонной поверхности, то происходит ин15 тенсивное расслоение материала по плотност м его частиц. Легкие компоненты «всплывают на поверхность сло и сдуваютс потоком воздуха.The optimal range of the opening angle d 15-20 ° has been skillfully established. Reducing the angle ot is less than 15 ° or; increasing it more than 20 ° reduces the separation effect. Moreover, if a layer of material moves along an inclined surface, then an intensive separation of the material according to the density of its particles occurs. Light components "float to the surface of the bed and are blown away by the air flow.
Изобретение по сн етс схемой.The invention is illustrated by the scheme.
Предлагаемый способ может быть осу20 ществлен в устройстве, содержащем метатель исходной смеси, средство дл подачи воздушного потока (на чертеже не показаны ), а также наклонную поверхность 1 с лотком 2 дл отвода т желых частиц.The proposed method can be implemented in a device containing an initial mixture thrower, means for supplying an air stream (not shown), as well as an inclined surface 1 with tray 2 for draining heavy particles.
