Abstract

PURPOSE: To dry damp sand efficiently while circulating with heated air, by combining a vessel main body shaped in inverted conical form in the lower part with an elevatable pipe to blow up sand by sending in hot air.
CONSTITUTION: A hot air feed pipe 8 provided with a plug body 9 of inverted conical form in the lower end part and a hot air blow-out hole 12 is elevatably installed in a vessel main body 1 shaped in cylindrical form in the upper part and inverted conical form in the lower part. Large-diameter sand blow-up pipes 13 having multiple holes 16 are coaxially fitted to the pipe 8 at intervals 18. By lowering the hot air feed pipe 8, a sand take-out port 3 in the vessel main body 1 is closed with the plug body 9, and sand 22 is introduced from a take-in port 2 to fill up the vessel 1. Then, hot air is sent into the pipe 8 and is injected from the blow- out hole 12, thereby blowing up the sand 22 in the neighborhood through the pipes 13. After heating and drying the sand 22 while circulating as shown by the arrows, the plug body 9 is lifted together with the pipe 8, and the take-out port 3 is opened, then the sand 22 is taken out on a hopper 21.
