Abstract

The invention relates to the field of slime water treatment, in particular to a multi-stage sedimentation rake-free concentration device capable of uniformly distributing materials. The device comprises a feeding assembly, a flow guide assembly, a clean coal collecting assembly, the flow guide assembly comprises a central groove body, slime water and a chemical agent flow from the upper part of the central groove body to the inner side wall of the central groove body through the feeding assembly, and then flow to the middle of the central groove body through the flow guide assembly, bubbles after reaction carry fine coal slime to move upwards into the clean coal collecting assembly, the clean coal collecting assembly is located above an outlet of the flow guide assembly, and the clean coalcollecting assembly is sequentially provided with a central material collecting area, a bubble removing area and a flow guide settling area from middle to outside. The device has the advantages thatthe structure of a traditional multi-stage concentration tank is integrated, and the occupied area of the traditional multi-stage concentration tank is greatly reduced.

Embodiment Construction

[0047] The utility model relates to a multi-stage subsidence rakeless thickening device with uniform distribution, which includes a material feeding component, a diversion component, and a clean coal collecting component. The guide assembly includes a central tank 21 with a cylindrical portion at the upper end and a funnel at the lower end. The central tank 21 is a cavity structure, and the feeding assembly is arranged above the cavity of the central tank 21. The central tank The lower end of the body 21 is provided with a first discharge port 24 . The coarse coal slime gradually settles to the top of the first discharge port 24 of the central tank 21 and deposits to a certain amount, and is discharged through the first discharge port 24, and the material discharged from the first discharge port 24 is collected , used for medium coal blending or as building materials to increase economic income.
