Background

The thickener is solid-liquid separation equipment based on gravity sedimentation, and is usually a cylindrical shallow groove with a cone bottom formed by taking concrete, wood or metal welding plates as structural materials. The ore pulp with the solid weight of 10-20% can be concentrated into the underflow ore pulp with the solid content of 45-55% by gravity sedimentation, and the thickened underflow ore pulp is discharged from a bottom flow port at the bottom of the thickener under the action of a rake which is arranged in the thickener and runs slowly. The upper part of the thickener produces cleaner clarified liquid (overflow) which is discharged from the annular chute at the top.

After the overflow is discharged, the existing clarified liquid still carries ore sand with lower solid content, and if the clarified liquid is directly discharged, a large amount of solid ore sand can still be lost due to larger discharge amount.

Based on the above, the utility model designs a recycling device for the return water of the mineral separation thickener to solve the problems.
