Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the accompanying drawings.

[0021] like figure 1 As shown, a multi-product flotation column sorting device of the present invention includes a flotation column, and the flotation column includes a roughing column 9 and a refining column 2 sleeved on the outside of the roughing column 9 . The diameter ratio of the roughing column 9 and the refining column 2 can be adjusted according to the buoyancy of minerals, and the diameter ratio is 1:1.2-1:2.

[0022] The upper part of the roughing column 9 is provided with a feeding pipe 10 passing through the beneficiation column 2, the bottom of the roughing column 9 is provided with a tailings discharge pipe connected with the tailings box 15, and the lower part of the roughing column 9 is arranged sequentially from top to bottom. There are circulating ore pulp extraction pipe 4 and circulating ore pulp feeding pipe 8, wherein the circulating ore pulp fe...

Abstract

The invention discloses a multi-product flotation column sorting equipment and method. The equipment includes a roughing column and a selection column set outside the roughing column. The upper part of the roughing column is provided with a feeding pipe, and the bottom of the roughing column There is a tailings discharge pipe, and the lower part of the roughing column is equipped with a circulating pulp extraction pipe and a circulating pulp feeding pipe. The inside of the selection column is also equipped with a stabilizing plate and a conical cylinder. The stabilizing plate is located above the circulating pulp extraction pipe, and the conical cylinder is located between the circulating ore pulp extraction pipe and the circulating pulp feeding pipe. The top of the selection column is equipped with a foam concentrate collector. The bottom of the selection column is provided with a medium ore discharge pipe, and the inside of the selection column near the bottom is also provided with an air distribution pipe connected to the air pump. The invention has the advantages of simple structure, convenient operation, flexible adjustment of product structure, and effectively solves the problems of clean coal entrainment and tailing coal leakage existing in the existing multi-product flotation.

Description

technical field [0001] The invention relates to a multi-product flotation column sorting device and method, and is especially suitable for sorting fine-grained coal slime with a large content of high-ash fine mud. Background technique [0002] With the improvement of coal mining mechanization and the deepening of mining depth in my country, the quality of raw coal has deteriorated, and the content of primary and secondary fine-grained pulverized coal in raw coal is increasing. Therefore, the efficient separation of fine-grained pulverized coal is directly related to the selection Economic benefits of coal plants. [0003] Flotation is currently the most effective method for separating coal slime, and commonly used flotation equipment includes flotation machines and flotation columns. The flotation machine has the following defects: the flotation machine has multiple tanks connected in series, and the motor power, stirring intensity, and aeration volume from the first room to...
