DEVICE FOR STACKING METALLIC PIGS INTO A PACKET Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: pneumatic feeder has a horizontal cylindrical housing with a bunker, feed, wind and mixing chambers and a worm. A forked vibration cultivator whose rod interacts with the worm loops is hung on the horizontal springs in the bunker and in the mixing chamber. A rotatory paddle wheel is mounted on the floor of the mixing chamber in order to stir up the material coming into the chamber. The worm has an initial impermeable section with loops having a step aerating section with blades and a terminal impermeable section with loops having a step decreasing in the direction of the exhaust window of the housing. The transported material is thickened before the aerating zone. After that it is stirred up by the indicated blades. Hot air from the wind chamber passes through the given material, holes, a netted ring and goes to the diversion branch pipe. After that the dried off material is thickened as loops in the terminal zone, unloaded into the mixing chamber onto the paddle wheel and is transported into the stand pipeline by the air flow coming through the bottom of the mixing chamber. EFFECT: enhanced reliability and effectiveness of feeders during the pneumatic transportation of moistened loose materials. 1 cl, 7 dwg
