Abstract:
PURPOSE: To spread feed water to an entire water tank even if a quantity of the water is little and to easily collect scale by uniformly providing many pores at a bottom of a doughnutlike cylindrical water tank, and annularly arranging a plurality of water discharge ports for supplying circulating water for sprinkling to the tank at a suitable interval at inner or outer peripheral side of the tank.
CONSTITUTION: A sprinkling tank 5' is formed by solidly laying 12 sprinkling plates 32 having pores 35 regularly opened in a circumferential direction at a bottom in a doughnutlike cylinder made of an otter frame 31. Water supply tubes 34a-34e raised and branched from a lower pump 7' are distributed in an inner cylinder of an inner frame 30, allowed to protrude to an intermediate part in a water tank via holes formed substantially at an intermediate level in the frame 30, and water discharge jigs 33a-33f are mounted at its end. A feed water port in which water is discharged is directed from above obliquely forward down. Accordingly, even when a quantity of the water is little, the water is immediately circulated to an outer peripheral side of the tank, arrived at an outer peripheral side of the tank and sprinkling is started through the pores at the bottom around the tube.
