2. Description of the Related Art A conventional drum shaker watering method is shown in FIG.
As shown in, a thermocouple 42 is attached to the inlet side of the drum shaker 41 to convert the temperature of the sand 49 in the drum shaker 41 into a voltage, which is connected to the temperature controller 43 via the compensating lead wire 44.
When the sprinkling start temperature is set by the temperature controller 43 and becomes higher than the set temperature, the solenoid valve 4 of the sprinkling pipe 45 mounted in the drum shaker 41 by the sequencer 48.
6 is opened, cooling water is made to flow to the water sprinkling pipe 45, and water is sprinkled from the water sprinkling nozzle 47 attached to the water sprinkling pipe 45. The supply of the cooling water to the sprinkling pipe 45 is divided into several stages according to the temperature of the sand 49, and in a certain temperature range T1 to T2, water is supplied to one sprinkling pipe 45 at 15 liters / dispersed water, and the higher temperature range T2 to T3. In the higher temperature range T3 to T4, water is supplied to the two water spray pipes 45 and 30 liters / dispersed water is supplied, and in the higher temperature range T3 to T4, water is supplied to the three water spray pipes 45 and 45 liters / dispersed water. Table 1 shows such a relationship that the number of sprinkling pipes 45 for supplying water increases as the temperature rises.

However, in the drum shaker 41, the hot casting 48 and the sand 49 that have been unframed from the sand mold are mixed, and the thermocouple 42 directly contacts the casting 48, so the temperature is measured as a temperature higher than the actual temperature of the sand 49. Sprinkle more water than necessary,
The thermocouple 42 may break. Further, since the temperature of the sand 49 is measured at the inlet side of the drum shaker 41 and the temperature of the recovered sand 50 discharged to the outlet is not measured, this state continues for a long time even when the above-mentioned abnormality occurs. Clogging or dust occurs.
