Abstract
Изобретение относитс к пневматическому транспортированию сыпучих материалов. Цель изобретени - повышение надежности. Винтовой пневматический питатель содержит шнек с полым валом 6, подающий материал в смесительную камеру 3. Конец шнека закреплен у задней по направлению подачи материала стенки смесительной камеры 3 на подшипнике 12, который насажен на ось 11. В оси 11 выполнен центральный газоподвод щий 14 и радиальные каналы 15. На оси 11 и на внутренней поверхности шнека закреплены шайбы 16 и 17, образующие лабиринтный канал 18. При подаче в канал 14 газ через радиальные каналы 15 проходит в кольцевую полость 25, а затем через лабиринтный канал 18 и далее через кольцевой зазор между торцом шнека и фланцем 13 в смесительную камеру 3, предотвраща попадание сыпучего материала из камеры 3 к подшипнику 12. Надежность питател повышаетс за счет увеличени долговечности подшипника 12. 1 з.п. ф-лы, 2 ил.This invention relates to the pneumatic transportation of bulk materials. The purpose of the invention is to increase reliability. The pneumatic screw feeder contains a screw with a hollow shaft 6, the feed material into the mixing chamber 3. The end of the screw is fixed at the rear in the feed direction of the material of the wall of the mixing chamber 3 on the bearing 12, which is mounted on axis 11. The axial 11 has a central gas supply 14 and radial channels 15. The washers 16 and 17 are fixed on the axis 11 and on the inner surface of the screw, forming a labyrinth channel 18. When fed into the channel 14, the gas passes through the radial channels 15 into the annular cavity 25, and then through the labyrinth channel 18 and further through the annular the gap between the end of the screw and the flange 13 to the mixing chamber 3, preventing ingress of particulate material from the chamber 3 to the bearing 12. The feeder increases reliability by increasing the durability of the bearing 12. 1 ZP f-ly, 2 ill.
