Abstract

PURPOSE:To adjust mechanically and automatically moisture with good accuracy by feeding out continuously at a constant rate the recovered sand which is temporarily stored in a hopper, measuring the temp. and the moisture content thereof and spraying successively a required amt. of water to the sand fed out in accordance with the result of said measurement. CONSTITUTION:An unfixed amt. of recovered sand S is charged from a conveyor 1 into a hopper 2, and the level of sand S is detected with sensors 5-7. A conveyor 3 is driven by a control device 11 to feed out continuously the sand S at a constant rate from a gate mechanism 4. The temp. and moisture content of the fed-out sand S are respectively continuously measured with sensors 15, 16, and the results thereof are fed to a control device 19 which calculates the required amt. of the water to be sprayed to the sand S. On the other hand, the presence of the sand S is detected by a sensor 13, and a stop valve 29 is opened. Stop valves 26-28 are adequately opened in accordance with the result of the above- mentioned calculation for the amt. of the water to be sprayed to spray water from nozzles 20-22 to the sand S. The accuracy in the moisture adjustment is thus considerably improved and the control device is made simple.

In order to generate ES, it is necessary to lower the temperature of the recovered sand and supply moisture to the recovered sand. Therefore, it is necessary to spray water on the recovered sand to cool it with the heat of vaporization and increase the moisture content. However, in general, recovered sand after demolding is transported in an indefinite amount, and the temperature and moisture content vary greatly depending on the electric resistance welding and shape of the cast product. amount of water mechanically and automatically.
Frequent spraying was difficult for non-'1:9.

The level sensor (6) J'f! of the collected sand (S) is in the middle level. When the height rises above point J, the belt conveyor (3) is driven and the recovered sand (
The height and width of S) are defined, and quantitative cutting is performed continuously. Feeding of the recovered sand (F3) into the hopper (2) continues until the level of the recovered sand (8) reaches the point of the L novel sensor (5), and when the level reaches the level sensor (5), the recovered sand The input of (8) should be stopped to prevent overflow. Therefore, when the presence of the recovered sand (S) that has been cut out is detected by the sensor (13), the on-off valve (29) is activated.
