Mixing prevention device installed in a mesh-bottom air chamber type wet gravity separator.

Abstract

The present invention provides a mixing prevention device to be installed in a mesh-bottom air-chamber type wet specific gravity separator that can efficiently recover the desired sorted material. [Solution] The mixing prevention device installed in a mesh-under-air-chamber type wet specific gravity separator having a sorting tank, a pulsating tank, an air chamber, a mesh, a light product discharge port located at the upper end of one side wall of the sorting tank, an intermediate product discharge port located below the light product discharge port on one side wall of the sorting tank, and a sorted material input port located above the light product discharge port on the other side of the sorting tank comprises a plate-like member, one end of which is rotatably attached to the upper end or vicinity of the opening of the intermediate product discharge port provided on one side wall of the sorting tank, the plate-like member being formed of a perforated plate extending substantially across the entire width of the sorting tank.

Claims

1. Mixing prevention device installed in a mesh-under-air-chamber type wet specific gravity separator having a sorting tank into which the material to be sorted is introduced, a pulsating tank filled with a sorting medium, an air chamber disposed within the pulsating tank, a mesh located between the sorting tank and the pulsating tank, a light product discharge port located at the upper end of one side wall of the sorting tank, an intermediate product discharge port located below the light product discharge port on the one side wall of the sorting tank, and a material to be sorted input port located above the light product discharge port on the other side of the sorting tank, The tank comprises a plate-shaped member, one end of which is rotatably attached to the upper end or vicinity of the opening of the intermediate material discharge port provided in the wall on one side of the sorting tank, The mixing prevention device is characterized in that the plate-like member is formed of a perforated plate that extends substantially across the entire width of the sorting tank.

2. The mixing prevention device according to claim 1, characterized in that the other end of the plate-like member is shaped to have a plurality of recesses and protrusions alternately within the plane of the plate-like member.

3. Mixing prevention device installed in a mesh-under-air-chamber type wet specific gravity separator having a sorting tank into which the material to be sorted is introduced, a pulsating tank filled with a sorting medium, an air chamber disposed within the pulsating tank, a mesh located between the sorting tank and the pulsating tank, a light product discharge port located at the upper end of one side wall of the sorting tank, an intermediate product discharge port located below the light product discharge port on the one side wall of the sorting tank, and a material to be sorted input port located above the light product discharge port on the other side of the sorting tank, A plate-shaped member, one end of which is rotatably attached to the upper end or vicinity of the opening of the intermediate material discharge port provided in the wall on one side of the sorting tank, The plate-shaped member comprises a sliding member disposed on the plate-shaped member so as to be slidable in a direction opposite to the one end of the plate-shaped member, A mixing prevention device characterized in that the plate-like member and the sliding member are formed from a perforated plate that extends substantially across the entire width of the sorting tank.

4. The mixing prevention device according to claim 3, characterized in that the other end of the slide member is shaped to have a plurality of recesses and protrusions alternately within the plane of the plate-shaped member.
