Abstract

The invention belongs to the technical field of slime water treatment and specifically relates to a parabolic grading concentration tank. The invention designs the grading principle according to the difference of parabolic tracks of coal slime particles in different shape, weight and size in a liquid medium. The parabolic grading concentration tank at least comprises a drug adding system, a feeding system, a concentration tank body, a first draining mud-lagging plate unit, a second draining mud-lagging plate unit, a first adjustable vibrating plate device and a second adjustable vibrating plate device; the quantitative addition of the drug can be realized in a manner of mixing the drug with the ore pulp once while passing by an annular drug disperser; the ore pulp after being mixed once can be added again according to the practical requirement by a secondary dosing pipe in the feeding system; a big horn-shaped drug dispersing port and a surrounding zigzag structure thereof can violently disperse the ore pulp flowing out of a small horn-shaped dispersing port; the slime water is deeply cleared by a free settling area formed by encircling of an annular separating plate in the concentration tank body. The parabolic grading concentration tank has the advantages of simple structure, low construction cost, low maintenance load, obvious effect, and the like.

Description

technical field [0001] The invention belongs to the technical field of coal slime water treatment, and in particular relates to a parabolic grading concentration pool. Background technique [0002] With the shortage of coal resources in my country and the improvement of coal mining mechanization, the deterioration of coal geological conditions has led to a decrease in the grade of raw coal mined from underground mines. During the on-site production process, the slime phenomenon is serious, and the slime treatment becomes more difficult. In particular, the operating pressure of the flotation link is increased. [0003] Coal slime is rich in a large amount of clay minerals, such as kaolinite, illite, montmorillonite, etc., which makes it more difficult to treat coal slime water. How to efficiently treat slime water is one of the research focuses of current scholars. To this end, design a device that can achieve high-efficiency slime concentration and clarification of circula...
