Abstract

The invention discloses a dry discharging device for tailings of a circular pipe through multiple force fields and a use method. The device comprises a drum (1), wherein a spiral separating mechanism (3) is arranged in the drum (1); one end of the spiral separating mechanism (3) is connected with a driving mechanism; the spiral separating mechanism (3) comprises a suction filtration pipe (4); air vents (5) are distributed on the suction filtration pipe (4); a filter screen (6) and a filter element frame (7) are successively arranged outward along the radial direction of the suction filtration pipe (4); and spiral blades (8) are distributed on the filter element frame (7). The dry discharging device has the characteristics of high separating efficiency, simple structure and process, low failure rate, low maintenance cost and equipment cost and good solid-liquid separating effect.

Description

technical field [0001] The invention relates to equipment and a use method for tailings pulp dry discharge treatment, in particular to a tailings pulp dry discharge device and a use method. Background technique [0002] Tailings dry discharge is to realize the solid-liquid separation of tailings slurry to obtain tailings with relatively low water content. The main technology used is to adopt methods such as concentration classification and filtration, flocculation and sedimentation classification according to the nature and state of the slurry, among which Concentration classification and filtration are mechanical methods. According to the properties and characteristics of different types of pulp, different dry discharge processes, methods, and mechanical equipment can be used for tailings dry discharge treatment. In the beneficiation process, if we want to realize tailings dry discharge, the main problem to be solved is to realize the separation of water and solids in the ...
