Tailing slurry collection buffering feeding device and method

Abstract

The invention relates to a tailing slurry collection buffering feeding device and method. The device comprises a box, a flow guiding collection barrel, a mixed overflowing buffering barrel, a feeding pipe, a discharging pipe and a sieve, wherein the box is provided with a top plate and a base, the flow guiding collection barrel is fixed below the top plate of the box and extends downwards in the height direction of the box, the mixed overflowing buffering barrel is fixed above the base of the box and extends upwards in the height direction of the box, the feeding pipe is communicated with an inner cavity of the flow guiding collection barrel, the discharging pipe is arranged at the lower portion of the side wall of the box, and the sieve is arranged inside the flow guiding collection barrel. The upper edge of the mixed overflowing buffering barrel is not lower than the lower edge of the flow guiding collection barrel. The barrel diameter of the mixed overflowing buffering barrel is larger than that of the flow guiding collection barrel, and an annular overflowing opening is formed between the mixed overflowing buffering barrel and the flow guiding collection barrel. An annular buffering space is formed between the mixed overflowing buffering barrel and the side wall of the box. Collection, mixing, pressure reduction and energy dissipation of tailing slurry are achieved, so that the tailing slurry is stably and slowly fed to a tailing slurry concentration and storage facility for filling.

Description

technical field [0001] The invention relates to a mine mining and filling system, in particular to a tailing mortar collecting and buffering feeding device and method auxiliary for mine filling, which realizes tailing mortar collecting and mixing, decompression and energy dissipation, and stable and gentle feeding. Background technique [0002] The tailings feeding method of the current filling system is that the tailings slurry from the dressing plant is directly transported to the tailings slurry concentration and storage facility (sand bin or deep cone thickener) for filling, and mixed with flocculant to accelerate the tailings. Sedimentation and concentration. There are certain problems in this feeding method: there is a certain residual pressure in the tailings slurry conveyed from the bottom flow of the concentration tank of the concentrator, and it will generate a large impact force when directly entering the tailings slurry concentration and storage facilities, which...

AI Technical Summary

Problems solved by technology

There are certain problems in this feeding method: there is a certain residual pressure in the tailings slurry conveyed from the bottom flow of the concentration tank of the concentrator, and it will generate a large impact force when directly entering the tailings slurry concentration and storage facilities, which will interfere with the settlement and concentration of the tailings. Effect, increase the amount of flocculant added, increase operating costs, and affect the overflow water quality of tailings concentration and storage facilities
