Background
The tailings produced in the production process of a metal mine concentrating mill carry a large amount of water and need to be further concentrated, usually, the tailings are concentrated to 40-60% of mass concentration by using a high-efficiency thickener, and the concentrated tailings are discharged to a tailing pond or a filling workshop, and meanwhile, supernatant fluid overflows from the upper part of the high-efficiency thickener. The conventional feeding cylinder of the high-efficiency thickener is a cylinder, and no other structure is arranged in the feeding cylinder, so that the feeding cylinder has no barrier effect on tailings and moisture entering the high-efficiency thickener. Because the tailings produced by the concentrating mill have large flow and concentration, the tailings for concentrating have large kinetic energy, and therefore, the tailings can be disturbed after entering the thickener, the sedimentation of particles on a settled layer is influenced, and the supernatant is disturbed, so that the overflow supernatant is mixed. In addition, the conventional feeding cylinder can not isolate foreign matters mixed in the tailing of the ore dressing, so that the rake pressing accident of the thickener is frequently caused. In view of the above, there is a need for an improved feeding cylinder of an existing high-efficiency thickener.
