JPS5653724A - Granular adsorbent material discharge device in packed type filter unit - Google Patents

Abstract

PURPOSE: To enable titled materials to be exhausted surely without going into the unit by inserting double pipes having valve action into a required number of conical granular adsorbent material exhaust chambers and providing a nozzle pipe in the position upper than the double pipes.

CONSTITUTION: A blower unit, a fine powder-capturing filter and a drum can for storage are connected to one end of an inner pipe 19 and the inner pipe 10 is rotated by remote operation to first communicate the charcoal exhaust port 22 of the inner pipe 19 to the charcoal exhaust port 20 of the outer pipe 18 in the charcoal exhaust chamber 12 of the 1st position from the right side. Then, the charcoal in the chamber 12 is exhausted through the inner pipe 19 from the exhaust ports 20, 22 by the adsorption force of the blower unit. Since the angle of inclination of the side wall 15 of the chamber 12 is larger than the angle of repose of the charcoal, the charcoal falls by gravity and is exhausted by suction. Next, the inner pipe 19 is rotated to communicate the exhaust port 22 of the inner pipe 19 to the exhaust port 20 of the outer pipe 18 of the next chamber 12, whereby the charcoal is exhausted. When the charcoal is wet, hot air is spouted from the injection ports 24 of a nozzle pipe 14, whereby the charcoal is dried and exhausted.
