Abstract
Description
Technical Field
[0001] The present application relates to the field of sand and gravel processing equipment, and in particular to a strong cooling type cooling and mud removal integrated machine. Background Art
[0002] The used sand that has been processed in the casting production and basically restored its performance can be reused. In sand casting, 1 to 7 tons of used sand will be produced for every ton of castings produced. There are basically two ways to use used sand, namely, reuse of used sand and reuse of used sand after regeneration. After the casting mold is poured, if the binder in most of the molding sand has not undergone irreversible changes, the original performance of the molding sand can be restored by removing impurities, cooling after ash absorption and remixing. This treatment method is called reuse of used sand. Generally, only molding sand bonded with clay can be reused.
[0003] The high-temperature sand discharged from the roasting furnace generally needs to be sucked out before being cooled. The regenerated sand needs to be stirred during the ash suction process so that the dust on the regenerated sand can be lifted up and sucked away. Direct cold spray cooling will cause the dust on the high-temperature sand to scatter and escape into the air, resulting in a poor environment. The first solution requires additional power to suck out the dust and stir it before cooling, while the second solution directly cools down and raises dust to pollute the environment. Therefore, there is room for improvement. Utility Model Content
