Abstract

Изобретение относитс к классификации трнкоизмельченных материалов Ьри сухом помоле и м.б. использовано b металлургической, энергетической и Ь;ругих отрасл х промышленности. Цель Изобретени - повышение эффективности разделени за счет осуществлени перечистки крупного продукта внутреннего конуса (к) 2 сепаратора в противо- точном движении газового потока. Сепаратор включает коаксиально расположенные основани ми вверх наружный К 1 и внутренний К 2. На выходе из полости между К I и 2 в полости К 2 уста (ОThe invention relates to the classification of crushed materials by dry grinding and m. used in the metallurgical, energy, and b industries; The purpose of the Invention is to increase the separation efficiency due to the re-cleaning of a large product of the internal cone (k) 2 separators in the opposite flow of the gas flow. The separator includes coaxially located upwardly external K 1 and internal K 2 at the base. At the exit from the cavity between K I and 2 in the cavity K 2 mouth (O

Description

132132

новлены поворотшш лопатки 3. В нижней части К 1 и 2 установлены соответственно патрубки (П) 7 и 6 вывода крупного продукта. Система перечистки крупного продукта внутреннего К 2 выполнена в виде П 8.подачи вторичного газа. Выходной торец П 8 расположен в П 6 в плоскости, перпендикул рной оси П 6, и направлен в сторону, противолежащую К 2, Материал в потоке воздуха поступает через П 4 в нижнюю часть К 1, Здесь сечение пылевоз- душного потока расшир етс , скоростьThe rotates of the blades are updated. In the lower part of K 1 and 2, the nozzles (P) 7 and 6 of the outlet of a large product are installed, respectively. The system of cleaning out a large product of domestic K 2 is made in the form of P 8. supply of secondary gas. The output end of П 8 is located in П 6 in a plane, perpendicular to the axis of П 6, and is directed in the direction opposite to К 2, the Material enters the air flow through П 4 in the lower part of К 1, Here the cross section of the air-dust flow expands

Claims

1. Separator for separating powdered materials, including outer and inner cones arranged coaxially with their bases upward, turning blades mounted at the outlet of the cavity between the cones

into the cavity of the inner cone, the inlet of the air suspension into the lower part of the outer cone, the elbows of the large product from the lower parts of the cones, the suction nozzle in the upper edge of the outer cone and the cleaning system of the large inner cone, so as to improve separation due to the re-cleaning of a large product of the inner cone in the opposite direction of the gas flow, the re-cleaning system of a large product of the inner cone is made in the inlet of the supply nozzle secondary gas, the output end of which is located in the nozzle of the large product from the inner cone in the plane perpendicular to the axis of the E. THAT nozzle.

2, the Separator according to claim 1, the discharge pipe of the secondary gas supply pipe is directed in the direction opposite to the inner cone.
