Description

[0002] In the casting production process, foundry sand is widely used for making sand mould and sand core, and in the molding and core-making process, foundry sand needs to bear the action of high-temperature metal liquid, for example, when pouring molten iron, the temperature can be as high as 1300-1500 DEG C, and after contacting with high-temperature metal liquid, the temperature of foundry sand will rise sharply, which makes foundry sand in high-temperature state after completing a casting process, and if not cooled, the high-temperature foundry sand cannot be directly used for molding and core-making again, which will affect the quality and performance of sand mould and sand core, and further affect the quality of castings, casting is a continuous or batch production process, and needs to quickly turnover foundry sand, and in a large-scale casting workshop, the amount of foundry sand is extremely large, and if relying on natural cooling, the cooling time is too long, which will lead to low production efficiency, for example, an automatic casting production line can need to process several tons of foundry sand per hour, and if there is no effective cooling device, the supply speed of foundry sand cannot meet the production rhythm, which will cause the stagnation of the whole production line.

[0003] However, the structure design of part of the cooling device can cause uneven heat conduction of foundry sand in the cooling process, for example, in some drum-type cooling devices, foundry sand can accumulate in the drum, so that the internal foundry sand cannot fully contact with the cooling medium, leading to slow cooling speed and poor cooling effect, like a traditional sand drying drum, foundry sand in the drum body will accumulate in the lower half of the drum body under the action of gravity, and foundry sand far away from the outer wall of the drum body is difficult to contact with the outer wall of the drum body, causing uneven cooling, and affecting the overall cooling efficiency.

[0004] Therefore, we provide a foundry sand cooling device to solve the above problems. UTILITY MODEL CONTENTS
