Claims:A preliminary cooling of moulding sand by precooling setup
1. The pre cooling setup consists of a sand detector, Y- Type Valve, Sand Homogenizer and Temperature sensor mounted on it.
2. The setup as tendency to reduce the temperature of moulding sand to 37 oC.
3. According to claim 2, the setup is used to cool the sand, without affecting the properties.
4. According to claim 1, sand homogenizer has effective homogenize of hot sand towards the top.
5. According to Claim 4, if the sand temperature is greater than 70 oC, Y-type valve opens at stage 2 and sprinkle the water.
, Description:First the sand from the shakeout enters into stage 1, where sand detector will detect the presence of sand in the conveyor then Y- type opens and water will be sprinkled, then sand homogenizer will homogenise the sand so hot sand will be on top, temperature will be sensed in temperature is above 70-degree, Y – type valve opens and sprinkle water to it. So, the sand before enters to existing setup it will be in the optimal range.
