(54) УСТРОЙСТВО ДЛЯ СЕПАРАЦИИ И КЛАССИФИКАЦИИ СЫПУЧИХ А АТЕРИАЛОВ певое сопло 12 генератора 13 третьего потока с каналом 14 дл  поовода рабочей среды. Генераторы 9 и 13 закреплены на поовижном корпусе 15 с крот тейном 16, св занным с корпусом 1 с помощыо направп юшей трубы 17 и винтового механизма 18. В зоне сопла 10 генератора 9 смонтирован кольцевой криволинейный коллектор 19 с каналом 20 дл  подвода рабочей среды н каналом 21 дл  отвода частиц материала. Корпус 1 включает также канал 22 дл  отвода частиц материала. Сыпучий материал, подаваемый через воронку 5 и канал 6, засасываетс  рабоче средой, выход щей и сопла 3, и направл етс  по каналу 7 Рабоча  среда, выход  ша  из сопла 10, образует текучий барьер, обтекающий поверхность торца 8, В этом месте наиболее легкие частицы материала подхватываютс  текучим барьером рабочей среды, выхрд щей из сопла 10, и направл ютс  по кольцевому пространству между корпусом 1 и генератором 2 в канал 22. Более т желые частицы материала проникают сквозь текучий барьер и попадают в зону коллектора 19, где под действием потока рабочей среды, поступающей по каналу 20, происходит втора  стади  отделени  частиц материала, которые отвод тс  по Каналу 21. Самые т желые частицы материала, про шедшие через коллектор 19, подхватываютс потоком рабочей среды, выход щей из сопл 12, и отвод тс  по кольцевому пространств между генератором 13 и корпусом 15. С помощыо винтового механизма 18 мо но перемещать корпус 15 относительно кор пуса I, регулиру  тем самым положение сопла 1О относителыю торца. 8 канала 7. П J . « Е3 Формула изобретени . 1.Устройство дл  сепарации и классификации сыпучих материалов, содержащее корпус, генератор н направл ющий канал основного потока, генератор второго потока, расположенный вблизи выхода канала и образующий текучий барьер, пересекающий основной поток, каналы дл  подвода и отвода рабочей среды и материала, о т л и ч а ющ е е с   тем, что, с целью повышени  точности классификации, генераторы потоков выполнены в виде кольцевых эжектпзрных сопел, а выходной торед канала основного потока имеет криволинейную поверхность, обтекаемую текучим барьером. 2.Устройство по п. 1, о т л и ч а KJ- щ е е с   тем, что сопло второго потока установлено с возможностью регулир вани  его положени  относительно выходного торца канала основного потока. 3.Устройство по п. 1, о т л и ч а ю щ е е с   тем, что на корпусе в зоне второго сопла монтирован кольцевой криволинейный коллектор дл  подвода дополнительной рабочей среды и промежуточного отвода частиц материала. 4.Устройство по п. 1, о т л и ч а torn е е с   тем. Что за соплом второго потока установлено сопло третьего отвод щего потока, совпадающего на направлению с основным потоком. Источники информации, прин тые во внимание при экспертизе: 1.

(54) DEVICE FOR SEPARATION AND CLASSIFICATION OF BULK AND ATERIALS; first nozzle 12 of the generator 13 of the third stream with channel 14 for conveying the working medium. The generators 9 and 13 are mounted on the rear housing 15 with a mole 16 that is connected to the housing 1 by means of a guide pipe 17 and a screw mechanism 18. In the area of the nozzle 10 of the generator 9, an annular curvilinear collector 19 is mounted with a channel 20 to supply the working medium to the channel 21 for removal of particles of material. The housing 1 also includes a channel 22 for removal of particles of material. Bulk material supplied through the funnel 5 and channel 6 is sucked in by the working medium coming out of the nozzle 3 and guided along channel 7 the working medium, the outlet of the nozzle 10, forms a fluid barrier flowing around the surface of the end 8, At this point the lightest the material particles are picked up by the fluid barrier of the working medium ejected from the nozzle 10, and directed through the annular space between the housing 1 and the generator 2 into the channel 22. The heavier material particles penetrate the fluid barrier and enter the collector zone 19, where under the action of flowIn the working medium entering through channel 20, a second stage of separation of material particles takes place, which are discharged through Channel 21. The heaviest material particles passing through the collector 19 are picked up by the flow of working medium leaving the nozzles 12 and discharged through the annular spaces between the generator 13 and the housing 15. With the help of the screw mechanism 18, the housing 15 can be moved relative to the housing I, thereby adjusting the position of the nozzle 1O relative to the end face. 8 channel 7. P J. E3 Claims of Invention. 1. A device for separating and classifying bulk materials, comprising a housing, a generator and a main flow channel, a second flow generator located near the channel exit and forming a fluid barrier crossing the main flow, channels for supplying and discharging working medium and material, This is due to the fact that, in order to improve the classification accuracy, the flow generators are made in the form of annular ejector nozzles, and the output torque of the main flow channel has a curvilinear surface streamlined by a fluid barrier rum. 2. The device according to claim 1, which is KJ-ee so that the nozzle of the second flow is installed with the possibility of adjusting its position relative to the output end of the main flow channel. 3. The device according to claim 1, which is such that an annular curvilinear collector is mounted on the body in the area of the second nozzle to supply additional working medium and intermediate removal of material particles. 4. The device according to claim 1, of tl and h a torn e e so. That behind the nozzle of the second flow is installed the nozzle of the third diverting flow, which coincides in the direction with the main flow.
