ABSTRACT:
A thermal reclaimer apparatus (14) for thermally removing from the used foundry sand the organic matter that is present therein. The subject thermal reclaimer apparatus (14) includes chamber means (26) in which the used foundry sand is heated to a predetermined temperature for a preestablished period in order to accomplish the burning away of the organic matter that the used foundry sand contains. The chamber means (26) includes inlet means (32) provided at one end thereof and outlet means (50) provided at the other end thereof. Feed means (34) are cooperatively associated with the pipe means (36) and thereby with the inlet means (32) for feeding the used foundry sand through the inlet means (32) into the chamber means (26). The subject thermal reclaimer apparatus (14) further includes rotating means (44) operative for effecting the rotation of the chamber means (26) as the used foundry sand is being heated therein. The chamber means (26) has cooperatively associated therewith burner means (40) located at the same end thereof as the outlet means (50). The burner means (40) is operative to effect the heating of the used foundry sand to the desired temperature within the chamber means (26). Tumbling means (46, 48) are provided inside the chamber means (26) to ensure that the used foundry sand is constantly turned over, i.e., tumbled, and that the lumps therein are broken up as the chamber means (26) rotates. Lastly, the used foundry sand from which the organic matter has been removed leaves the chamber means (26) through the outlet means (50).
