DEVICE FOR PNEUMATIC TRANSPORT OF POWDER-LIKE MEDIUM FROM BINS OF ASH-CATCHERS Russian patent published in 2009 - IPC B65G53/16 B65G53/40 

FIELD: machine building.

SUBSTANCE: in the device for pneumatic transport of powder-like medium, containing source of air excess pressure communicated to receiver, sectional transmission pipe-line with feed pipe of air to its butt, distributive pipe, pipelines for air, electromagnetic valve with control pulse generator, for each bin of ash-catcher there are installed inlet branch pipe with located vertically saddle at outlet port, choke with air feed pipe to choke, located in casing. Bottom cavity of casing is communicated through the reducing sleeve with located horizontally saddle at outlet port, cavity of the second casing - to sectional transport pipeline. In cavity of the second casing there are located the second choke with feed pipe of air to choke. Each pipeline for air by its outlet end is communicated to inlet ends of feed pipes of air to chokes of two casings of each section, and by inlet - to distributional tube. At each choke, at surface adjacent to pipe of air feed it is fixed pressure tube with ability of enveloping by external surface of outlet end of air feed tube to choke at its mixing.

EFFECT: reliability enhancement.
