Field of the Invention The present invention relates to a dust collecting apparatus for dust generated from a cooling tank, and more particularly, to a dust generated when quenching is performed by immersing a casting having a core therein in a cooling liquid. Suitable for collecting dust.

６２号公報参照）。2. Description of the Related Art Conventionally, for example, a cylinder head of an engine, a casting produced by a mold provided with a core made of resin sand is completely heat-treated after the core sand is completely removed in the sand removing step. (For example, solution treatment → quenching → aging)
However, from the viewpoint of improving the efficiency of sand removal and energy saving, recently, castings with core sand inside are sent to the heat treatment step, and the sand removal of core sand is also performed in the heat treatment step. (For example, Japanese Patent Publication No. 60-42
No. 62).

砂の除去を行うことができるというものである。That is, when a casting with core sand contained therein is introduced into a solution heating furnace and heated, in addition to the original solution treatment of the casting, the resin that solidifies the sand is vaporized and removed. When the casting is subsequently immersed in the cooling liquid in the cooling tank and rapidly cooled, in addition to the original quenching of the casting, the cooling liquid in contact with the casting suddenly vaporizes It is possible to remove the core sand from the surface of the casting to efficiently remove the core sand.

粉塵を捕集しないでそのまま外部に排気している。By the way, in the cooling tank for cooling the casting with the core sand therein as described above, the steam generated when the cooling liquid is vaporized causes an ascending air current to fly up the dust, so that the upper part of the cooling tank is cooled. The hood is covered with a hood and a duct is connected, and suction is performed with a suction blower to prevent dust from scattering around the cooling tank. However, since a large amount of water vapor is contained in the sucked air, when trying to separate dust from this, the filter will get wet with a normal dust collector (see, for example, No. Sho 62-1725). It cannot be used because it cannot be used, and it is forced to separate it using a wet dust collector or collect dust and exhaust it to the outside.
