FIELD: pneumotransport. ^ SUBSTANCE: invention relates to discharge of loose materials, such as alumina, cement or other aggressive dust forming materials from flexible container by means of compressed air. Proposed chamber feeder has intake chamber with cover, discharge pipeline with intake branch pipe, and discharge nozzle with knife device. Flexible container is placed in intake chamber. Intake branch pipe is installed for free travel along discharge pipeline being furnished with knife device to cut upper part of flexible container. Discharge pipeline is furnished with intake branch pipe travel stop. Intake branch pipe installed for movement in discharge pipeline at aeration of material in process of delivery of compressed air through discharge nozzle into intake chamber provides its lowering to into material layer to close to discharge nozzle. Such free travel of intake branch pipe provides maximum capacity of chamber feeder. ^ EFFECT: reduced power consumption for bringing material out of chamber feeder, increased reliability of its operation. ^ 5 dwg |
