Abstract

1. Способ сепарации сыпучей смеси в текучей среде, заключающийся в гравитационной подаче частиц, аэродинамическом монотонно растущем воздействии на них под острым углом к вертикали каскадом плоских струй и выводе готовых фракций, причем перед аэродинамическим воздействием на частицы смеси течение каждой струи переводят в режим развитой турбулентности путем расширения их по вертикали до слияния друг с другом со сбойной или близкой к ней формой течения и образованием в начале каждого межструйного пространства всех смежных струй двух циркуляционных зон, верхней и нижней, отличных по размерам, отличающийся тем, что перед формированием циркуляционных зон осуществляют резкое изменение направления течения струй из вертикального на почти горизонтальное с последующим их сжатием по вертикали. ! 2. Устройство для реализации способа сепарации сыпучей смеси в текучей среде по п.1, содержащее бункер с вибролотком, установленный под ним генератор с расположенными одна под другой и под острым углом к вертикали жесткими стенками, шаг и ширина расположения которых увеличивается сверху донизу, и связанный с источником подачи воздуха под давлением и охваченный боковыми стенками, а также сборники фракций, отличающееся тем, что конец каждой жесткой стенки по всей ее длине снабжен расположенной к ней под углом дополнительной стенкой, ширина которой меньше расстояния между смежной сверху жесткой стенкой, которые расположены со сдвигом по горизонтали, с образованием зазора относительно нижней жесткой стенки, и камеры поворота воздушного потока на входе в зазор, при этом камеры поворота и зазоры увеличиваются сверху книзу. 1. A method of separating a granular mixture in a fluid, which consists in the gravitational supply of particles, aerodynamic monotonically increasing exposure to them at an acute angle to the vertical by a cascade of flat jets and the withdrawal of finished fractions, and before the aerodynamic effects on the particles of the mixture, the flow of each jet is transferred to the developed turbulence mode by expanding them vertically to merge with each other with a faulty or close to it flow pattern and forming at the beginning of each inter-jet space all adjacent jets of two circuits different size zones of the upper and lower ones, characterized in that before the formation of the circulation zones, a sharp change in the direction of the stream of jets is carried out from vertical to almost horizontal, followed by their vertical compression. ! 2. A device for implementing the method of separating a granular mixture in a fluid according to claim 1, containing a hopper with a vibratory tray, a generator mounted under it with rigid walls located one below the other and at an acute angle to the vertical, the pitch and width of which increases from top to bottom, and connected to the air supply source under pressure and covered by the side walls, as well as fraction collectors, characterized in that the end of each rigid wall along its entire length is provided with an additional wall located to it at an angle, the width the distance is smaller than the distance between the horizontal wall adjacent to the top, which are horizontally shifted to form a gap relative to the lower rigid wall, and the air flow rotation chamber at the entrance to the gap, while the rotation chambers and gaps increase from top to bottom.
