A deep-cone thickener for concentrating mine tailings slurry

By introducing a roller and cam-driven rotary disc design into the deep cone thickener, the problems of low separation efficiency and unstable concentration of high-viscosity tailings slurry are solved, achieving more efficient solid-liquid separation and stable water quality in the clarification zone, thus improving the overall efficiency of tailings treatment.

AI Technical Summary

Technical Problem

Existing deep cone thickeners have low solid-liquid separation efficiency and unstable concentration when processing high-viscosity tailings slurry, which affects the efficiency of tailings transportation and purification. In addition, the water in the clarification zone is polluted, leading to a decline in mineral processing indicators.

Method used

A deep cone thickener was designed. By installing rollers and cams on the drive shaft, the rotating disk inside the guide plate is driven to rotate, which breaks the contact surface between the flocs and the guide plate, thereby enhancing the floc separation effect. The separation effect is further enhanced by the reverse rotation of adjacent rotating disks. At the same time, rollers are set to roll on the inner wall of the cone to stabilize the rotation of the drive shaft and the rake frame, and to prevent flocs from floating up and contaminating the clarification zone.

Benefits of technology

It improved the concentration efficiency of tailings slurry, stabilized the underflow concentration, reduced water pollution in the clarification zone, and enhanced the mineral processing indicators and the treatment effect of subsequent treatment equipment.

Abstract

The application discloses a deep-cone thickener for concentrating mine tailings slurry and relates to the technical field of mine equipment. The top surface of the conical barrel is fixedly connected with a bridge, the top surface of the bridge is fixedly connected with a speed reducer, the output end of the speed reducer is transmissionally connected with a transmission shaft which is coincident with the axis of the conical barrel, the side surface of the transmission shaft is fixedly connected with multiple groups of cross frames, one end of the cross frame close to the inner wall of the conical barrel is fixedly connected with a mounting seat, and the adjacent two mounting seats which are vertically arranged are rotationally installed with a roller between them. In the application, when the transmission shaft drives the rake frame to slowly rotate, the roller which is tangent to the inner wall of the conical barrel makes the rotation of the rake frame more stable, and the concentricity of the rake frame and the transmission shaft is ensured; in addition, the rotation of the roller makes the rotating disc which is rotationally installed in the inner part of the guide plate reciprocatingly rotate through the cam, so that the contact surface between the floc attached to the guide plate and the rotating disc is damaged, and the floc is separated from the two guide plates.
