Rake-free concentrator

The invention relates to the field of slime water treatment, in particular to a rake-free concentrator. The rake-free concentrator comprises a feeding assembly, a diversion assembly and a clean coal collecting assembly, the diversion assembly further comprises a central tank body, coal slime water passes through the feeding assembly, flows with a medicament from the upper part of the central tankbody to the middle part of the central tank body, and is diffused in all directions, after reaction, residual mineralized bubbles and fine coal slime float upwards to a bubble removing area in the clean coal collecting assembly, the coal slime water in the center tank body flows in the center tank body after being defoamed, along with continuous filling of the coal slime water, the coal slime water above the center tank body overflows out of the center tank body to a diversion settling area in the clean coal collecting assembly, and the diversion settling area is arranged on the outer side wall of the center tank body
