Slime water classification pool based on parabolic classification theory

Abstract

The invention belongs to the technical field of slime water processing, in particular relates to a slime water classification pool based on the parabolic classification theory. The invention conducts the classification principles based on the differences in the parabolic trajectories of the coal slime particles with different shapes, weights, and sizes in the liquid medium; the pool at least comprises a pool body, an adjustable vibration board device, and a drainage mud sluggish board structure; the adjustable vibration board device comprises a vibration board, a hinge chain, flexible shock vibration pieces and an ultrasonic regulation device, and is arranged in the middle of each grading room, and the effect of speeding up the grading of coal mud particles and settlement can be achieved; the drainage mud sluggish board structure comprises an oblique board, a bracket, an axle, a bearing, and a manual rotating valve, the pool body is divided into five grading rooms and is connected with the pool bodies at the same time, the angle of the oblique board can be adjusted 360 degrees to achieve the full guidance of the coal mud particle classifications. The invention has the characteristics of being simple in structure, low in construction cost, small in maintenance workload and obvious in effect, and the like.

Description

Technical field [0001] The invention belongs to the technical field of slime water treatment, and specifically relates to a slime water classification pool based on the parabolic classification theory. Background technique [0002] With the scarcity of coal resources in our country and the improvement of coal mining mechanization, the deterioration of coal geological conditions has caused the grade of gross coal mined from underground mines to decline. In the on-site production process, the phenomenon of slime sludge is serious, and the difficulty of slime treatment is increased. In particular, the operating pressure of the flotation process is increased. In order to change the current situation, try new methods and new processes, and accelerate the development and research of new coal preparation equipment, which has become the top priority of the "13th Five-Year Period". [0003] The slime is rich in clay minerals, such as kaolinite, illite, montmorillonite, etc., which makes t...

Problems solved by technology

[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 the slime water and increases the dosage of chemicals in the flotation process
