ABSTRACT:
A self-contained device for the pneumatic conveyance of incoherent solid materials by pneumatic pulse waves is disclosed, the improvement consisting in that a container for the material is provided with a feeding point for a pressurized gas, first and second valve means being also provided for alternately intercepting the flow of the material into the initial trunk of the conveyance line on the one hand, and the vent of the gaseous fluid and the flow of the solid material on the other hand. A second gas-feeding point is also provided to supply impulsive gas jets in alternate sequence with the pulses of said first-named feeding point. A dust takeup device is provided, having a reservoir placed in intermediate points of the conveying pipeline and functionally connected with valve means which act also as dust-collecting and dust-discharging means. The advantage of the device is that, especially for incoherent materials which are difficult to handle due to the high production of dust, the task of the filters is relieved and filter-clogging is efficiently prevented.
