Abstract

To provide an apparatus for reclaiming foundry sand that has a fluidized bed that prevents slits from being clogged. The apparatus comprises a tank (3) for reclaiming the foundry sand, a tank (4) for fluidization, an upper portion of which in an upstream side is connected to a bottom of the tank for reclaiming the foundry sand, the tank for fluidization transporting the reclaimed foundry sand and fine powder that drop from the tank for reclaiming the foundry sand, a dust hood (5), and a lower portion of which communicates with an upper portion of the tank for fluidization in a downstream side, the dust hood collecting the fine powder in the tank for fluidization, wherein a fluidized bed (6) in the tank for fluidization has a plurality of inverted V-shaped covering members (13) and a plurality of V-shaped flooring members (14), wherein the inverted V-shaped covering members and the V-shaped flooring members are horizontally and alternately provided so that the inverted V-shaped covering members are at any point above a vertically corresponding point of the V-shaped flooring members, and wherein gaps between end portions of the inverted V-shaped covering members and end portions of the V-shaped flooring members are formed as inclined slits (15) for supplying air.
