Old and useless dry core sand shell regeneration line

Technical Field

The utility model relates to the technical field of waste dry core sand shell recovery, in particular to a waste dry core sand shell regeneration line.

Background

And (3) coating sand, wherein the surface of sand grains is coated with a layer of molding sand or core sand of a solid resin film before molding. There are two film-coating processes of cold method and hot method: dissolving the resin with ethanol by a cold method, adding urotropine in the sand mixing process to coat the urotropine and the sand on the surface of sand grains, and volatilizing the ethanol to obtain precoated sand; the heat method is to preheat the sand to a certain temperature, add resin to melt the sand, stir the sand to coat the resin on the surface of the sand, add urotropine water solution and lubricant, cool, crush and screen the sand to obtain the precoated sand. The method is used for steel castings and iron castings.

At present, all units using precoated sand to make cores and shells have the problems of dry core damage, incomplete sand shells and incomplete poured partial sand shells which cannot be completely incinerated and utilized.
