Abstract

The invention discloses a fine-fraction high-concentration tailing filling and thickening device which comprises a tank body part, a wind-water slurry making system, an underflow conveying system, an electric control system, a flocculating agent preparing and adding system and the like. The wind-water slurry making system comprises an annular water pipe group and an annular gas pipe group; annular water pipes of all layers of the annular water pipe group and annular air pipes of all layers of the annular air pipe group are located at different height positions and distributed in an inverted cone shape, the annular water pipes and the annular air pipes of each layer are respectively connected with a plurality of high-pressure rubber water (air) spraying pipes, valves and external water (wind) slurry making nozzles; and the annular water pipes are connected with a water supply and drainage header pipe, and the annular air pipes are connected with an air supply and exhaust header pipe. By means of the fine-fraction high-concentration tailing filling and thickening device, the material storage capacity is large, the mining and filling circulation efficiency of a mine is improved, no power part exists, fault points are few, power consumption is low, and the operation cost is low; and long-time continuous steady-state slurry discharging is achieved, the stability of technological parameters and the working efficiency of filling operation are improved, the concentration capacity of the thickening device is improved, and the continuity of filling operation of the thickening device is guaranteed.

Description

technical field [0001] The invention relates to a fine-grained high-concentration tailings filling and thickening device, which belongs to the technical field of tailings treatment. Background technique [0002] The traditional mine filling process is to fill the coarse-grained tailings into the underground, and discharge the fine-grained tailings to the tailings pond. Tailings ponds occupy a large amount of land, and the existing tailings ponds are short of storage capacity. The construction and maintenance of tailings ponds also bring a certain economic burden to enterprises. It is difficult to implement new tailings ponds, and there are ecological and environmental protection problems. Although the traditional graded coarse tailings cemented filling can meet the current production needs, the discharge of fine tailings to the tailings pond has huge safety hazards, and an innovative filling process is urgently needed. Shandong Gold Group thoroughly implements the requireme...
