Abstract: Disclosed is a multi-stage sedimentation rake-free thickening device. The device includes a central tank. A diversion sedimentation zone is arranged on the outside of the center tank. The diversion sedimentation zone includes an annular diversion sedimentation screen and a concentrated magnetic shower. The annular diversion sedimentation screen includes an annular groove spirally arranged around a central groove body. The annular groove is sequentially arranged with second spoiler baffles along the length direction. The lower bottom plate of the annular groove is also provided with second underflow discharge port. Multiple second inclined plate diversion discharge pipe is arranged under the corresponding second underflow discharge ports. The outlets of all the second inclined plate guide discharge pipes are collected to the second underflow discharge pipe, and the settled water is discharged from the second overflow discharge pipe arranged at the end of the annular groove.

Abstract: Disclosed is a reverse flow multi-stage sedimentation rake-free thickening device relating to the field of slime water treatment. The device includes a feed assembly, a guide assembly, and a clean coal collection assembly. The guide assembly also includes a central tank body and coal slurry flows from the upper part of the central tank body to the inner side wall of the central tank body through the feed assembly and the medicament, and then flows to the middle of the central tank body through the guide assembly. After the reaction, the bubbles carry the fine coal slime and move up to the clean coal collection assembly. The clean coal collection assembly is located above the outlet of the guide assembly, and the clean coal collection assembly is sequentially provided with a central collection area, a defoaming area, and a diversion settlement area from the middle to the outside.
